How can I make php save the form data into a session before the user leaves the page without pressing the submit button? Some members leave the page and return afterwards wondering where their already entered data is. I hate to be a contrarian (not really), but there is a paradigm for using web forms. If you want the internet to save your data, you have to press the little button. If you don't, then it won't be saved. Not hard to figure out, not hard to do. If you have to go do something else while you're in the middle of a form, open a new tab/window and do it. When you come back to your original form, the data will still be there (but again, not *saved* until you hit the little button). Sorry, I just get cranky with people who won't follow the rules. There are rules and then there's stupidity based on tradition. The fact that websites previously threw away whatever work you had done because you automatically got logged out of your session after half an hour of typing does not mean you should call this a rule that should be adhere to. Google figured it out and did so well: backup automatically and let the user discard manually - not the other way round that leads to lost work. Apart from that, I note that the OP has seemingly managed to solve the problem and all these emails are rather pointless. Concur, and this is nothing to do with the web; http only constrains that the data should be POSTed or PUT; not /when/ a save action is triggered. Functionality is in the realm of the application, and if the client application (in this case the web page) determines that information should be iteratively saved, then that's what it should do. see google docs, gmail etc for real world examples. And a few BANK sites could do with considering waring people that they will time out before you have time to actually write in their message box for on-line emails which you have to use since they will not accept off-line ones. I had a complex message FROM them to answer - and save just told me the seesion had timed out! Bank solution - I should have copied their message to a word processor, and then copied the answer back later ... perhaps they should add that with a warning when trying to use their email page ;) -- Lester Caine - G8HFL - Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Array differences
I have the following scenario:
$array1 = array("12", "34", "56", "78", "90");
$array2 = array("12", "23", "56", "78", "89");
$result = array_diff($array1, $array2);
print_r($result);
This returns:
Array
(
[1] => 34
[4] => 90
)
However what I really want is a two-way comparison. I want elements that
don't exist in either to be returned:
34 and 90 because they don't exist in $array2, AND 23 and 89 because they
don't exist in $array1. So, is that a two step process of first doing an
array_diff($array1, $array2) then reverse it by doing array_diff($array2,
$array1) and merge/unique the results? Any caveats with that?
$array1 = array("12", "34", "56", "78", "90");
$array2 = array("12", "23", "56", "78", "89");
$diff1 = array_diff($array1, $array2);
$diff2 = array_diff($array2, $array1);
$result = array_unique(array_merge($diff1, $diff2));
print_r($result);

[PHP] would there be an interest in having htmlMicroscope include dygraphs?
htmlMicroscope (that i wrote and opensourced) can be used to look at very big arrays easilly in a browser. I fully intend to fix the final bugs and release a real 1.3.0 release, and not abandon that project.. In fact, i could use a simple project to work on atm, to re-focus myself on useful work and a useful day-night rythm (as made apparent by my recent off-topic and weird posts to this list).. I would like to include http://www.danvk.org/dygraphs/ into htmlMicroscope. Would you think it usefull? htmlMicroscope can be downloaded through the googlecode link in my signature.. Again, please excuse my recent off-topic posting to this list. My psychiateric out-patient help team has confirmed that they were informed by a member of this list of my recent [OFF-TOPIC] post in dutch (of which i cannot even be sure if "everyone got that mail"), but i do thank you people for reporting me to said psychiateric help team. My contact with them is good, they did not "invite me for a irl conversation". I'm allowed to stay at my parents and heal myself (from sleep-deprivation) under the guidance of my dear parents. Please people, just +1 or -1 this idea of adding dygraphs to htmlMicroscope. The coding should be simple, and i do promise to clean up the 1.3.0-beta-rc1 to a real 1.3.0 version that works properly for displaying arrays with unicode data, json-arrays-as-keys, etc, ranging 100-200mb in transport-to-browser-size.. Yes, i am a bit worried about being seen as the weird psycho on this forum. Psychotic i'm not, just sleep-deprived a bit, and i've slept very well in the past 72 hrs. Over 10hrs per 24hrs for the past 72hrs. So i'm healing, not degrading. And of course i'm taking (dutch brandname:) risperdal quicklets, as per my mum's orders (rather than a psych worker's "closed ward" orders).. I'll be doing house-cleanup in about a week, and will be spending nights at home in about 2 weeks, allowing me probably to put mediabeez.ws back up online for development versions of htmlMicroscope. Again, my apologies for poluting the list with what is considered too-off-topic Please do not inform the psych-services again of any posts of mine here mentioning telepathy. It was already reported to them, and they (Noortje) actually called me and we talked it over, that it shouldn't happen again, me posting private conversations onto some random list. My reasons for posting "[OFF-TOPIC] telepathy and psychiatery" to this list were simple; i was trying to alleviate the fears of other telepaths like me, to prevent _them_ from having to go through the hell of psychiateric closed wards...

Q: What is the result of $val > 0?
A: false.

Use an if statement for this kind of logic.
This is a fantastic example of false logic and an easy pitfall.
in fact this would make a great interview question!
to expand a little on the various scenarios (just for clarity, Rob is

$val = 1;

so no matter what value you set $val to; it's always true.
Fail on that last one. -1 is not equivalent to FALSE :B
well that's one job I'm not getting :p

Q: What is the result of $val > 0?
A: false.
Q: What is the value of $val?
A: 0
Q: Is 0 equivalent to false?
A: Yes!
Use an if statement for this kind of logic.
This is a fantastic example of false logic and an easy pitfall.
in fact this would make a great interview question!
to expand a little on the various scenarios (just for clarity, Rob is
right)
$val = 1;
1 > 0 equates to TRUE
is 1 equivalent to TRUE : YES
$val = 0;
0 > 0 equates to FALSE
is 0 equivalent to FALSE : YES
$val = -1;
-1 > 0 equates to FALSE
is -1 equivalent to FALSE: YES
so no matter what value you set $val to; it's always true.
Fail on that last one. -1 is not equivalent to FALSE :B
well that's one job I'm not getting :p
Well you DID get 66.7%. I've met "coders" that would stare at the answer
and still not understand :D

Concur, and this is nothing to do with the web; http only constrains that the data should be POSTed or PUT; not /when/ a save action is triggered. Functionality is in the realm of the application, and if the client application (in this case the web page) determines that information should be iteratively saved, then that's what it should do. see google docs, gmail etc for real world examples.

There are rules and then there's stupidity based on tradition. The fact that websites previously threw away whatever work you had done because you automatically got logged out of your session after half an hour of typing does not mean you should call this a rule that should be adhere to.

For each customer account we have a single Billing address but allow multiple service, technical, administrative, etc... contact entries. We must keep past entries for historical purposes too.

It was done this way because it is strictly a learning exercise. I had never created a DB with multiple tables, so I wanted to be able to contruct one using foreign keys, and be able to insert and retrieve from it. But the experiment continues. For whatever reason, scripts to query a DB that I have used for years are not working. I am thinking it has something to do with that I switched engines to innodb. So the lesson continues. Gary Gary: One of the concepts in OOP is identifying an object in terms of it's attributes and functions. The concept of defining tables is very similar. If you want to learn about foreign keys, then think of them as things that are foreign and not things that are similar. For example, a user has name, address, height, weight, color, language, etc. Those things can be listed in a single table. A item that can be purchased, like a chair has a title, description, weight, color, cost and such. Those things can also be listed in a single table. If a person buys a chair and the seller wants to create a record of the purchase, then all the seller needs to do is to record the buyer's and the chair's attributes. Now, the seller can either write down all the attributes for each buyer/chair sale OR reference them using foreign keys. User Table id = 123 name = tedd address = whatever Item Table id = 456 name = chair color = whatever Sales Table item sold = 456 buyer = 123 Done! Get the idea?

Re: [PHP] Solution
Tedd
I had four tables. name, (fname, lname) address(street, town, state, zip),
contact(phone, fax, email), comments (comments).
It was done this way because it is strictly a learning exercise. I had
never created a DB with multiple tables, so I wanted to be able to contruct
one using foreign keys, and be able to insert and retrieve from it.
But the experiment continues. For whatever reason, scripts to query a DB
that I have used for years are not working. I am thinking it has something
to do with that I switched engines to innodb.
So the lesson continues.

[PHP] Re: how to overload accessible methods
this is a class for corntab job, and the validation is very simple, just check if the status of user is active when cron job runs, if not, throws an exception, other developers won't want to overwrite this validation. which method of user class will be called is configurable via website backed page(we write the name of methods directly in to schedule table). Using private methods will solve the problem but since we write public methods for all the other cron classes, I just want to keep the style to make less confusion.

Some members leave the page and return afterwards wondering where their already entered data is. I hate to be a contrarian (not really), but there is a paradigm for using web forms. If you want the internet to save your data, you have to press the little button. If you don't, then it won't be saved. Not hard to figure out, not hard to do. If you have to go do something else while you're in the middle of a form, open a new tab/window and do it. When you come back to your original form, the data will still be there (but again, not *saved* until you hit the little button). Sorry, I just get cranky with people who won't follow the rules.

You arrive at the same place, but at what cost? In this case, I don't think the OP has provided us with enough information about his problem. If he is concerned that his users may return to a page and wants the fields filled with what the user previously entered, then that depends upon several different things, such as has the user shut down his browser, or has the user simply clicked the submit button and the page has been refreshed.

Change the first line of the switch to
switch(true)
and it will be functioning as you want. Normally, a switch has this
form:
switch($val)
{
case 1:
{
// statements
break;
}
case 10:
{
// statements
break;
}
default:
{
// statements
}
}
But PHP does allow you to use variable cases (as you have in your
example) if the value in the switch is a boolean (true or false). It can
be a little confusing if you're new to PHP (or programming in general)
but you'll get used to it after using it a few times.

Gary :
It not only looks redundant, but why two tables?
Why not "customers" or "users" or "subscribers" like so:
include(opendb.php);
$query="INSERT INTO users (first_name, last_name, street, town, state, zip)
VALUES('$first_name', '$last_name', $street', '$town', '$state', '$zip')";
$result=mysqli_query($dbc, $query) or die('Error querying database.');

I don't see any reason to separate the attributes of the person into
two different tables. Why do that?

That would mean that the class can only be extended as far as your
validation code allows, and the developers extending your class will
have little control over how anything is validated.

every method call so that they don't have to write more code and they
won't miss this validate?

why would you want to, is there a technical reason for wanting magic
functionality instead of "normal" functionality (+ wouldn't it make the
code much easier to maintain and debug if developers can see what is
called where, instead of just magic).
to answer though, you're best bet is probably to make an abstract class
with magic functionality and then extend with an implementing public class.
abstract class MagicUser
{
public function __call($name, $args)
{
//validate user
$this->_validate();
$this->_{$name}($args);
}
private function _validate()
{
//
}
private function _update($args)
{
//
}
}
class User extends MagicUser
{
public function update($args)
{
parent::update($args);
}
}

[PHP] how to overload accessible methods
As we all know, __call() can overload non-accessible methods,
eg.
Class User
{
public function __call($name, $args)
{
//validate user
$this->_validate();
$this->_{$name}($args);
}
private function _validate()
{
//
}
private function _update($args)
{
//
}
}
$user = new User();
$user->update() // will call _validate before _update automatically
BUT, if I want to make this update a public function, how can I call
the validate without call it inside update function explicitly?

If you want the internet to save your data, you have to press the little button. If you don't, then it won't be saved. Not hard to figure out, not hard to do. If you have to go do something else while you're in the middle of a form, open a new tab/window and do it. When you come back to your original form, the data will still be there (but again, not *saved* until you hit the little button). Sorry, I just get cranky with people who won't follow the rules.

You could use Ajax to grab the form data and send it to the server if you need though. However, I'm not really sure what your question is. Are people visiting your site, filling in a form, then pressing the back button to go somewhere else? If so, maybe they intended to not submit the form. Thanks, Ash http://www.ashleysheridan.co.uk

[PHP] Saving form data into session before leaving a page
Hello everybody, I have form where users enter data to be saved in a db. How can I make php save the form data into a session before the user leaves the page without pressing the submit button? Some members leave the page and return afterwards wondering where their already entered data is. Any ideas how to save into php session data before someone leaves the page?

I don't really know of any specific other examples as it's been a while since I've used Windows for anything now. The link you gave did say it was free though, so you don't really have anything to lose by installing it. Thanks, Ash http://www.ashleysheridan.co.uk

Two years ago when I first set up my own server with Linux and not Windows, I never had to deal with this. Perhaps the authentication has since then got stricter, but it should not be so much of a heck of a deal. I found this doc from ATT's website, http://helpme.att.net/pdf/uverse/uverse_hsi_qsg_english.pdf, so obviously the smtp server I provided earlier is probably not up to date. I think I will fiddle around with the php.ini file and see what else is there. Thanks. Alice _ Hotmail has tools for the New Busy.
