1. I can see that you have issues with anger. Have you thought about
seeing a therapist?

2. So because other lists aren't doing it, this one shouldn't also? I
wonder, would you jump off a bridge if everyone else was doing it too?

3. I'm not talking about spam sir. I'm talking about the addresses that
are subscribed to this mailing list that when sent an email immediately
send back some sort of stupid response like our friend [EMAIL PROTECTED]
did. Either he's been removed from the list or he's cleaned his inbox so
that emails are being accepted again.

4. Also it wastes bandwidth for the list owners and the people
subscribed. It just adds bloat and confusion. Here's analogy:

When I was little kid I used to go camping with my grandparents about
once a year. One of my favorite things to do was gather as many dry
leaves as I could carry and dump them on the fire. If I could carry
enough leaves, the fire would be completely covered and look like it had
been put out. But after waiting a few seconds the fire would consume all
the leaves and end up burning a little bigger than before.

Instead of throwing as many leaves on the fire as we can we should
instead put the fire out with water or sand.

The comparison is that your solution does not stop or even lessen the
problem, it just masks it. That's not how problems get solved.

[PHP] functions/methods and what they should return

[Chris W. Parker]

Hi people.

I'm working on a large application right now (complete ecom store) and
I'd like to get some feedback on something.

Each product that is in the database can have at least one attribute to
it (i.e. color, size, etc.). Right now I've got a method in my Products
class called ShowAttributes($id). This method, based on the ID passed to
it, will query the db and ultimately return a string that makes up the
drop down box for a form.

Am I better off doing this sort of thing in a function or having the
function only return the records I need and let the calling page handle
the display of the records?


What do you think about this?


Thanks,
Chris.

Hmm.. Ok. So right now I've got this (psuedo code):

function displayAttributes($id)
{
// query db
// store results in array

// perform logic that builds HTML string

// return HTML string
}

But instead you think I should do this:

function GetAttributes($id)
{
// query db

// get records

// return record array
}

function BuildAttributes($id)
{
$attributes = GetAttributes($id);

// format $attributes

// return HTML string
}

Is that what you're suggesting?

I don't understand this exactly. What do you mean by "can't break the

Yes. But this depends on how your setup is. You could try filtering by
filetype. Don't accept files with a .pif extension. You could filter by
subject (this virus/worm is called SoBig.F). You can find a list of
subjects this virus uses by visiting any one of the anti-virus vendor
websites.

As far as filtering what comes through the list, some people think that
shouldn't happen and other's think it should. Regardless, no one seems
to know how to get in contact with the list owners anyway so probably
nothing is going to happen.

3. Try a completely different code design so that you don't have to

(You may very well already know of these two functions and already
thought of what I'm going to tell you but I thought I should share
anyway.)

In that case maybe these two functions will get you going:

www.php.net/checkdate
www.php.net/getdate

I'm thinking this:

1. you get the date from the user
2. validate it using checkdate()
3. get the current date
4. compare the two dates to see if the users date is later than todays
date
5. return true or return false

Sound good?

Hmm... that's a lot of code. What exactly am I supposed to do with it?


But anways... To do what google does you'll have to figure out how many
records there are in total first. (At least that is how I do it.)

It goes like this.

1. someone searches for something
2. you pull back a complete list of records
3. count them
4. store the number somewhere
5. display the first ten results along with page numbers
6. user clicks next page
7. pass the stored record count to the next page
8. use the LIMIT query to pull back only the next records
9. dislpay the next records, use the stored value (that you passed in
step 7) to create your page numbers
10. rinse repeat


Does that help?

[PHP] verifying sql INSERTs

[Chris W. Parker]

Hi!

(MySQL)

What's the best way to determine a sql INSERT statement has executed
successfully?

What I've got is a function whose sole purpose is to add new staff
members to an app. I've written. There's a basic form that the user
fills out (first name, last name, email address) and submits. Only one
record per email address is allowed.

Here is a pseudo code version of what I have right now.

function insertStaffer($fname, $lname, $email)
{
$sql = "SELECT table WHERE email = '$email'";

if(1 or more records are found)
{
return 0; // means email address is already used
}
else
{
$sql = "INSERT INTO table ...";

return 1; // assume record inserted correctly
}
}

Now for my question: Should I just assume the INSERT INTO has worked
correctly (like I'm currently doing) and return a 1? Or should I verify
that the INSERT worked correctly (by using the MySQL last_insert_id()
function)?

Alternatively... maybe the mysql_query() function returns a true/false
status based on what happens? Hmm... I should look into that.


I'd appreciate any advice you have to give.


Thanks,
Chris.

OOhhh... You know, I already HAVE done this, and I just came to the
realization that if I've already got a constraint on the email column
then why the heck am I checking to see if the value is already there?
That's just a waste of resources.

I should instead just try to perform the INSERT and then if it fails I
know I've already got a record. If it doesn't I know everything is cool.

Good idea!

In that case I hope you're also incrementing your own IDs and not
leaving that up to the db either. You might also do yourself a favor and
write down each transaction instead of hoping the computer will do it's
job correctly. ;)

But seriously, how likely is it for a db/table to just drop it's
constraint? And in what situations would/could that happen?

[PHP] php equivalent to asp's instr()

[Chris W. Parker]

Hi.

I don't know why but I've had the darndest time trying to find an easy
equivalent of asp's InStr() function in PHP. I know there is
preg_match(), strpos(), and strstr(), but none of them work like I want
them to.

In fact, except for maybe preg_match(), I can't get any of them to work
right.

I want a function that will return true if the string is found, and
false if it is not found.

Like this:*

$needle = "&";
$haystack = "Belle & Sebastian";

if(FoundInString($needle, $haystack))
{
echo "found!";
}
else
{
echo "not found!";
}


Anyone have a function to share?


Thanks,

To display the output like you've got in your post you'd do something
like this:

(pseudo code)

$arrayOfEntries = GetEntries();

$previousDate = "";
foreach($arrayOfEntries as $entry)
{
if($previousDate != $entry['date'])
{
// show date header
// show comment for this record
}
else
{
// show comment only
}

$previousDate = $entry['date'];
}


Let me know if this helps (and if it doesn't too).

Well you could use cookies also but those can be tampered with.

Sessions aren't hard to work with really. All you need to do is start
the session, write a variable to $_SESSION if they have authenticated
successfully and then check for the existence of that variable on every
page. If it doesn't exist they have not authenticated.

Those are the basics.

Sorry I don't have a resource for you, but passwords shouldn't use

Well fortunately for me I don't have a signature nor do I have a
disclaimer added on each email. But I can answer your question anyway. I
use my work email address because I'm not supposed to access any other
email addresses. I mean I can create all the aliases I want for my
account but I can't use a personal email address during work time.

So yeah, that's why.

1. (not positive on this point so correct me if I'm wrong) you shouldn't
compare with !==. Instead us !=.

2. What does the following do?

for ($i=1; $i<=$entries; $i++)
{
if(empty($_POST["resolutions".$i]))
{
echo "empty!";
}
else
{
echo "not empty!"
}
}


You might also like to try isset() along with empty().

Yes. Remove those first ten lines (assuming they are removable) from the
original file you had them in and then include them in the old file with
include_once().

Then in the file you want to only include the ten lines just include the
smaller file.


Example: (I'm changing your 10 line requirement to 2 lines.)

Original.php:

Line 1
Line 2
Line 3
Line 4
Line 5

Take out Line 1 and Line 2 and put them in 2lines.php.

2Lines.php:

Line 1
Line 2

Then Original.php becomes this:

include_once "2Lines.php";
Line 3
Line 4
Line 5

Then in your other file that you need the 2 lines you can do just this:

NewFile.php:

include_once "2Lines.php";



HTH!

I don't think you're going to be able to do this in the way that you
want (I've been wrong before).

I think your only option is to somehow rip the lines that you want into
another file before you do the include.

You could try using the the file system to copy only certain lines to
another temporary file and then include that temp file instead of the
whole thing.

Another option would be to tweak the logic so that it's not so bloated.

Not true. www.php.net/require_once

The way I understand it (maybe you know something I don't?)
require/include_once only prevent an included file from being included
MORE than one time, hence the character string _once tacked onto the end
of include() and require().

It does NOT however include a file only when it's needed, it merely
includes it once.


Please correct me if I'm wrong.

I have only dabbled in this so I don't know the proper terms and
technologies used, but I'll try to pass on what I've learned.

It requires a few things.

1. PHP needs to send the proper header. (At the top of each page.)



2. You also need to send the correct language info from within the page
itself. I suggest going to a japanese page and looking at the source.

3. You need an editor that can handle the japanese language. I stopped
trying to make japanese pages because I could not find a suitable editor
(granted I didn't try very hard and I wasn't about to buy something).



Hope this helps!

I've never done this but can you give the two buttons the same name but
different values? Assuming the value of the button that is clicked is
the only value you sent you can clean up the code a little.

$buttonPressed = $_POST['button'];

($HTTP_POST_VARS is deprecated [afaik])

(also notice i put single quotes around the index, you should too)

your code:

> if ($continue) {
>   //Do something - usually go to another page
> } elseif {
> ($cancel) {
>   // Do something - usually go to another page
> } else {
>   //Do something

my code:

if ($button == "value1")
{
// do this stuff
}
elseif($button == "value2")
{
// do this stuff instead
}
else
{
// do this instead
}

> Is this inefficient or is there a better way to do this?

Yes it is because your testing only for the existence of a value and not
a specific value. This could allow a malicious user to fudge around with
your form, submit their own values, and possibly have your code react in
a way you wouldn't want it to.


your code:
> echo(NL);
> echo('' . $date . "");
> echo(NL);
> echo('' . $place . "");
> echo(NL);
> echo('' . $est_amt .
> ""); echo(NL);
> echo('' . $card . "");
> echo(NL);
> echo('' . $ccn . "");
> echo(NL);
> echo('' . $state . "");
> echo(NL);

How about this instead? (btw, i've never used NL so i'm going to assume
it's the equivalent of \n)

echo "$date\n"
."$place\n"
."$est_amt\n"
."$card\n"
."$ccn\n"
."$state\n";

Isn't that so much easier to read???

You're doing it wrong then (I think).

1. You should always initialize your loop counters.

i.e.

$x = 0;

while($x < 100)
{
$x++;
}

2. Don't use the same counter name in all your loops.

This is bad:

for($x=0;$x<100;$x++)
{
for($x=0;$x<100;$x++)
{
echo "i'm going to go on forever!!";
}
}

This Is Good(tm):

for($x=0;$x<100;$x++)
{
for($x=0;$x<100;$x++)
{
echo "Me happy now!!";
}
}



Does that help?

No. I don't think there is that option in html-kit, but I think that

If you (a person) can save the file as the proper type there's probably
no reason to send the header() function, or for that matter there would

Yes this is how I would expect it to work but it ended up not working

[PHP] autocomplete not working all of a sudden

[Chris W. Parker]

Hi everyone.

Pardon the crosspost but I figure if I'm going to post the same question
to two lists anyway, why not get it over with in one shot?


Ok so in an attempt to lessen Windows2k pro memory footprint I just
turned off three services. (1) TCP/IP NetBIOS Helper Service, (2) IPSEC
Policy Agent, and (3) Distributed Link Tracking Client.

Now the autocomplete functionality of IE is not working. IE used to save
all the search terms for google, now they're not there. I'm also working
on a project that requires a simple login, all my test usernames used to
be stored with the form but now they are not there anymore either.

I have no idea if either of those services had anything to do with or
not (it seems very unlikely that they are related) but it's the only
connection I can see.

Here's what I've done so far:

1. Turned all those services back on and then tried both google and my
login form again. Didn't work.
2. Checked the IE settings for autocomplete. They are correct.


Any ideas on how to get it working again?


Thanks,
Chris.

p.s. IE's address bar is still working (must be a separate function).

As it should. You don't want to store password information in a cookie,
that's why yahoo requires you to reenter each time.

The only thing a site should keep in a cookie regarding username and
password is the username. yahoo (as well as many other sites) offer the
option of saving the username in a cookie so that when you get back to
the site your username is automatically filled in. it probably helps
relieve the "i forgot my username" emails.

Oh I should respond to this as well.

This is just a little better than storing a plain text password. Reason
being
that the next person that uses that computer can read the cookie and
steal the hash. They would then be able to reverse* it and get the
password so they could log in like a normal user.

I messed around with it for a few days just trying to add two fields to
the product table but it so difficult to find where all the mysql db
errors were being generated I just gave up and decided to write my own
cart from scratch. ;)

I should clarify a little. I gave up after only trying to add two fields
because the other features that I needed in a shopping cart were WAY
more complicated than the two fields and I reasoned that if it was that
difficult to add two fields it's going to be near impossible to add what
I wanted. So I decided my time would be better spent developing my own
cart (what learning experience it's been!!). I would be able to extend
my own cart much more quickly and efficiently than I could anyone elses
code.

[PHP] speaking of php editors

[Chris W. Parker]

Hey everyone.

I am looking for an editor that will highlight the string
"{$array['index']['index']}" within a string.

For example:

+- gray +
|   |
|  +-- red ---+ |
|  |  | |
$variable = "The amount is {$amount[0]}.";


Is there anything out there that does this?

If you need more than two levels of classification I would suggest you
use a method called Modified Preorder Tree Traversal. You can read about
it here. http://www.sitepoint.com/article/1105

It's a little complicated at first but once you grasp the idea it starts
to make a lot of sense.

[PHP] help with arrays

[Chris W. Parker]

Hey people.

I've got an array like this:


[0] => Array
(
[0] => j
[fname] => j
[1] => j
[lname] => j
[2] => jj
[state] => jj
[3] => [EMAIL PROTECTED]
[email] => [EMAIL PROTECTED]
[4] => 0
[newsletter] => 0
)

Some cells might be empty so i want to replace every empty cell with
" ". I can easily do this with just the numerical index but I can't
figure out how to do the textual indices also.

Someone have a clue?

It's failing because the ' before the %d is closing the string.

Here's how I work out SQL stuffs:

$sql = "SELECT username\n"
."  , password\n"
."  , DATE_FORMAT(timestamp, '%d%m%y')\n"
."FROM custlogon";

$query = ($sql);


Althought it looks like it takes a lot more time to write (which is
true) it looks great when you are debugging.

echo "$sql";


Alternatively you should be able to do this:

$query = ("SELECT username, password, DATE_FORMAT(timestamp, '%d%m%y')
FROM custlogon");

Firstly you should be putting double quotes around every value in your
HTML tags.

Revised: (watch wrap)

echo "";

I also changed

". $chkSessionF[$i] ."

into

{$chkSessionF[$i]}

.

You can do it either way. I prefer the latter.

If you're not sure what a value is use print_r() to determine it.

echo "";
print_r($chk);
echo "";

Quick side note on the above code:

You cannot write it like:

echo "".print_r($chk)."";

It will not work.

I think your problem may just be the quotes around the values in the
HTML. Give it a shot.

[PHP] storing japanese in mysql (or pgsql)

[Chris W. Parker]

(I posted this to another list yesterday without response, so if it
looks familiar, that's why.)

Hi.

I'm working on a small study aid for myself (and anyone else that wants
to use it) and I could really use the ability to store Japanese
characters in a MySQL or pgsql db. Right now I've created a very large
array.

What I'd like to do is have a form that will allow me to add new
characters whenever needed. So far my attempts at this have failed. It
always seems that the extended characters get turned into their html
entity equivalents before they are inserted into the db.

I'm using euc-jp as the character set.


I'm pretty much lost with this. Anyone have experience with this that
they'd like to share? (on or off list is fine.)


Thanks,
Chris.

Well heck, that makes things easier!

What's the difference between using , or . for concatenation? (I thought

Gives me:

I tried this, and I think the comma was just slightly faster than the
period. But then again I didn't always get consistent results because I
was trying this out on a machine that is not very fast so the speed at
which is processes something varies quite a bit.

My conclusion was that it's not fast enough to bother changing all my
code, or start writing in a new way.


Although during some testing I did find that writing loops in the
following way is faster than normal.

$counter = -1;
while(++$counter < $amount)
{
// do stuff
}

It made a big enough difference on my slow machine to merit me writing
as many loops in this way as I can. (I think.)

I just mean the characters that you can't type unless you do something

I added that line to the [mysqld] section but there was no [client]

[client]
default-character-set = ujis

Each line in the [mbstring] section was commented out. So I uncommented
them. I also uncommented the mbstring extension.


I'm just about to restart both servers, so we'll see what happens.

[PHP] your method for validating forms

[Chris W. Parker]

Hey people.

I'm trying to come up with an easy way to validate forms. I've got an
idea and I'd like your feedback as well as suggestions and/or your own
methods.

My idea is to have a multi-dimensional array with fields: data and type.

Let's say you have a form with three fields. First Name (fname), Last
Name (lname), and Phone Number (phone). It's sent to a processing script
via GET. On the processing script you have the basics:



What I'd like to do is get rid of all the if's and what not and throw
them into a function. What I thought of doing to replace all this is:



The validateFormDate() function would be defined something like this:

function validateFormData($input)
{
foreach($input as $field)
{
switch ($field['type'])
{
case 'name':
// do the magic
break;
case 'phonenumber':
// do the magic
break;
}
}
}


The validateFormData() function will return false if there are no errors
to report.

For a form that has a lot of fields to validate I think this can make
things pretty easy.


So... what do you think?

I went to an ecom site today that used js validation but in a very slick
way. There were no popups to be seen. Instead, when I tried to add a
product to my cart without specifying some attributes a little red
message magically appeared on the page that said "Please choose a
color".

A client-side validation class would be usable imo if it doesn't utilize
popups. Not being experienced with js I can imagine that not using
popups and still warning the customer of a mistake would be complicated.

I prefer server-side but that's mainly just because I don't like js.

Haha... ummm... I... uhh... don't have a link because I made a mistake.

What really happened was when I clicked on a product on the site a small
popup window appeared. This window had very little information on it and
so was very light. When I clicked Add to Cart it submitted and refreshed
so fast I didn't see a flicker, and therefore it looked like it was
using some kind of client-side validation.

I rechecked it just now and noticed the flicker so that's how I knew I
was wrong.

But still this sort of client-side validation is something that will go
onto my long term todo list. And it's like Curt described, instead of
popping a window you make a  or  or something like that
appear.

[PHP] method to prevent multiple logons of same account

[Chris W. Parker]

Hi.

Ok I've got the logging in of customer accounts settled but what I need
to work into the system is that of preventing more than one instance of
the same account.

If I logon right now as testuser1 on ComputerA and then go to ComputerB
and login as testuser1 it'll work just fine. What I want to do is one of
the following: (a) prevent the second instance of testuser1 from
succeeding, (b) logoff the first instance of testuser1 when the second
instance authenticates.

I know I'll have to keep a database and store the following: username
(or user id), session id, time of login, and/or time of last action.

Option A is very easy. I can easily look in the database and see if that
person is already logged in. If they are found in the db I just refuse
the second login attempt. Option B on the other hand seems a little more
difficult. As far as I've thought it out so far I'll have to check the
db on each page request to see if the user is still valid. That is to
say, if the second attempt is allowed to login I would have to change
the users session id from the first instance to the second instance.
Then when the first instance goes to a new page the application would
say "Hey wait a minute buddy! Your session id is different than the one
in the database. You've either timed out or someone else has logged in
with the same username."


Am I thinking this through correctly? Comments?
