I am happy with my editor. It (BBedit) has good multi-file search-replace... and I can also generate that/a full list of where all is strtolower()..

Perhaps you should spend some time looking for a better text editor

Thanks a lot for taking a look Tommy,
I do have a decent text editor I use to code with... and had searched for
possible places where is the culprit strtolower() ... and so far no matter
which instances(s) I comment out, I cannot seem to turn off the behavior of the
library as a whole (either of them, or both) which is forcing the input CSS to
lowercase.
For example, I also just tried the exact place you suggested: this one:
[snip]htmlpurifier-4.4.0\library\HTMLPurifier\AttrDef\CSS\Font.php
...and changed line 45 to this:
//$lowercase_string = strtolower($string);//Govinda hack
$lowercase_string = $string;
but still no luck.

I hadn't posted on http://htmlpurifier.org/phorum because last time I did that
when I has also posted on stackoverlfow (SO), then the developer of
HTMLpurifier scolded me for the dupe ;-) .. and he has already posted a
comment on my (this new) SO post, saying just, "Hmm, that's silly of CSS Tidy.
Maybe we should change that default.". I assume he probably has a lot on his
plate, to the point that his answers are incredibly terse and not necessarily
very helpful.
I did see the message about CSStidy no longer being developed (if that is the
meaning behind "suspended"). Yet when i was researching it, many people were
still recommending it. No? Do you know/prefer something else for the purpose
of cleaning user-input CSS bound for an external style sheet?
Thanks

You need to get better tools. I found this with Notepad++ for Windows

I realize this had probably been covered countless times (best step

http://marc.info/?l=php-general&w=2&r=1&s=db+connect&q=b
and I am apparently missing something because when I input
"failed db connection"
at the top, in the search box, then it returns posts all over the
map, and also takes out the middle word in my search string (so now
it is just "failed db"). Why is that?
I also searched for "failed database connection" which does not
change my search input, but still the posts I found did not give me
enough clue to stop me from posting here now.

It's usually a simple thing since there are only 3 parameters so it's
something that you have likely mis-spelled or input in the wrong order.
It's not rocket science to figure it out, the docs are clear about how
it works.
But a likely guess maybe that you need to connect via localhost
instead of the full domain name.

Re: [PHP] Is there a way to un include a file
No. You could perhaps wipe out *EVERYTHING* in $_GLOBALS, which would be the included file and anything in the main file[s] that went before. If you need an environment that is that "pure" for testing or something, you can run a different PHP process on each file. Otherwise, you simply have to architect your application correctly. Some other solutions to this naming/scope problem include 'packages' which php doesn't have and 'namespaces' which php doesn't have and... There have been innumerable flame wars here and on Internals about the right way to add a new feature to do this, and I don't think there is any real concensus yet.

Re: [PHP] Is there a way to un include a file
AFAIK there's no function to un include a file, but i don't see a problem here, as when you include your second file, everything (all conflicting variables) will be overwritten. If you still have problems, you might want to use classes around your functions and variables.

Re: [PHP] Is there a way to get multiple values for a singleinput in a form submission?
Hi Mark,
Actually you can access this variable within Javascript in the following
manner:
function chgablacted() {
box = regs['myselect[]'];
value = box.options[box.selectedIndex].value;
if (value == 'some value') {
...
} else {
...
}
}
The name of the variable will include the brackets [].

The side effect that is -somewhat- undesirable is that it becomes

way to get around that problem though.

Re: [PHP] Is there a way to get multiple values for a single input in a form submission?
this is what I am trying to do:
On a web form I might have a select input with multiple selections
enabled, however I want to have access to the list within PHP after
submission.
1
2
so when this is submitted, I can see in the $HTTP_RAW_POST_DATA that
myselect is submitted twice...
...&myselect=1&myselect=2&...
However, the $_POST array only has the last value eg.
$_POST['myselect'] == '2'
This makes sense because the last value is assigned to the key 'myselect'.
Is there a function or alternate way that will get an array back
from the post-back without parsing through the $HTTP_RAW_POST_DATA
(which is not always available since the php.ini file can turn it
off)?
TIA
-MS
MS:
You're not asking for an array, but simply a return of what value
'myselect' is.
If your url is sending "&myselect=1&myselect=2&...", then something
else is wrong.
The following --
$what = $_POST('myselect');
echo($what);
-- should show you what's there.
Also, try print_r($_POST);
I have a very simple exampleof POST/GET at:

Re: [PHP] Is there a way to display data from database for Select Options in a form?
Jochem: Your method is long, probably takes more time to run, and is
therefore inefficient in this circumstance. There is a time and place
for a good solid reusable function, or even a class.
Of course things could go wrong when using mySQL connections, but
things can always go wrong.
Bringing people to use PHP on a higher standard? I am sorry, but that
is simply childish. There are plenty of kids that think their way in
programming is the best possible way, the only good way, and that
everyone else should try to imitate them. They also think that every
problem should be solved in the language they are strongest with.
Eventually one must learn that for every way of doing something, there
are at least 5 other ways. Higher standards? Or YOUR standards?
The situation determines the standards, not the programmer.

her original question:
"Is there a way to display data from database for Select Options in a form?"
the short answer is: 'yes'
but the way her original question was posted suggests that maybe she has
_absolutely_ no idea about how to use php... I mean google is able to
help her in theory:
http://www.google.com/search?num=100&q=generate+dynamic+select+box+PHP
either she has no idea what to search for or she was to lazy to try -
if the former then she should have not be ashamed to keep asking away, if
the latter then, well, who cares.
the reason I gave her what might be more than she can chew (the function)
was because:
a, her initial question was a bit vague (or rather broad)
b, to show that there can be a little more to generating dynamic elements
like select box.
c, to encourage generic code.
d, test her and she what her reaction is (hopefully she won't run away; instead
maybe she'll come back with a more specific question and DB data extraction)**

RE: [PHP] Is there a way to display data from database for SelectOptions in a form?
[snip]Let's look at it another way, why 70-80 lines of code when 4 will do it properly when done correctly?[/snip] I agree with this line of thinking especially for a new person to php. When I first read the solution that was so long I thought to myself "great and this person is new to php and now they are going to be scared of php." I really think one of the appeals of php is it's simplicity of getting things done and getting those things done quickly. Yes it's great having one function to output every select html form but is it really necessary?
Re: [PHP] Is there a way to display data from database for Select Options in a form?
the quickest solution and one that is easy to understand, I am no php
expert and have never claimed as such so why 'noob'?
Why is this such a poor method? if i type the HTML to be outputted
correctly then what validation is required? also I think Someone new
would run from your proposed solution

I am guessing that your php skills are not that hot. filling a select box
is php 101 here is function that generates a selectbox based on the given
'data' - now you have to go and figure out how to build the array $items
(which is passed as the first arg to this function) from the data in your table:
/** selectTag()
* generate an html select list using the given $items as options.
*
* @param array $items - list of items to display as options
* @param array $selected - value of select item in $items
* @param string $selectname - value of select tag's name attribute
* @param numeric $addnone- add a 'blank' option to the top of the list
*(different types depending on valuepassed)
* @param string $onchange - value of select tag's onchange attribute
* @param string $selectid - value of select tag's id attribute
* @param boolean $readonly - whether the select tag is readsonly or not
* @param array $readonly - whether the select tag is readsonly or not
* @param boolean $option_class_arr - optional CSS class names for
individual option tags
* @param string $selectHTMLattribs - passthru HTML (attributes for the
select tag)
*
* @return string
*/
function selectTag($items, $selected = '', $selectname = '',
$addnone = 0, $onchange = '', $selectid = '',
$readonly = 0, $option_class_arr = array(),
$selectHTMLattribs = '')
{
// must have an array of items
if (!is_array($items)) {
return '';
}
// determine the value of the selected item
$selected = strtolower(trim($selected));
// list of options we will generate
$opts = array();
// add item with value 0 ?
$add_none_value = 0;

case '1': // item display = 'none'
$zero_id_item = getStr('None');
break;
case '3': // item display = '0'
$zero_id_item = getStr('zero_digit');
break;
case '2': // item display = 'all'
case '4': // item display = 'all ' e.g. 'all 3'

} else {

$zero_id_item = $addnone;
}
}
break;
}
if (isset($zero_id_item)) {
$thisselected = ($selected > '') ? '' : ' selected="selected"';

$_SERVER['HTTP_USER_AGENT'] contains whatever the browser passes to the server to identify itself, which may be faked by certain browsers at the discretion of the user.

Actually it's not either...
Since you can't easily debug when generating XML, as malformed XML will STB,
I have this function which dumps out an array and recursively sub arrays.
It would be very useful to dump out the name of the variable as part of
this, as a lot of text is on the screen with all the tags and such.
It always annoyed me about print_r() that it doesn't tell you the variable
name either, so you have to always prefix it with an echo/print just above
the print_r.
/**

* @access public
* @paramstring $myArray the array to output in XML format
* @version 1.0

Well if you called someFunction('bar');
Function someFunction($myVar)
{
global $$myVar;
echo "the variable name is '$myVar' and has the value of ".$$myVar;
}
But that relies on the global and is also a bit messy in a recursive
situation.

There is no such function. Usually the person asking it is doing something very newbie-ish, and very wrong. I know, cuz I was that person, many many years ago. :-) I think what I needed that time was "variable variables"... The other thing that tends to bring up this question is somebody trying to write a custom error handler, not knowing about http://php.net/trigger_error and friends. Though that only gets you the line number and filename where the error occured, not a specific variable name. If for some reason one *NEEDS* to have "names" and variables and to know what a variable's "name" is, you *probably* want to use an associative array and use the "keys" as your names. Hopefully this is helpful to the Original Poster, or somebody some day.

RE: [PHP] Is there a way to get a variable name as a string?
That won't work. Then I will get what the VALUE of $bar is set to. I want
the actual text "bar". Basically everything after the "$" -- ie. The NAME of
the VARIABLE, not it's contents.
The closest I've come so far is to do this.
Function myname($foo)
{
echo "variable named $foo has the contents $$foo";
}
Myname('bar');
Which is pretty lame.

Maybe something like:

$return_value="the variable name passed in is ".$foo;
return $return_value;
}
echo myname($bar);
Just a guess.

This seems perfectly reasonable approach. Once you have assigned a file to 'robert' in the database, then you can let 'robert' download the file -- or even a zip file with all 200 files in it. The downloaded file will have the correct Windows extension -- or they will after 'robert' unzips them, and Windows will open the right software, if 'robert' has it installed and the machine is configured correctly. If it's not installed or the machine isn't configured correctly, there is nothing you can do about it from PHP. Then 'robert' can work on them, and, when they are finished, they can upload the edited files. You can track when 'robert' downloaded the files, and when 'robert' uploaded the files. If you want to do it one file at a time you could track each and every download/upload -- but it would be very painful for 'robert' to download every single file and upload every single file. Most likely, just knowing that 'robert' downloaded 200 files, took 43 minutes to work on them, and uploaded them again, is plenty of info to track productivity. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Chris Hayes wrote: It takes a lot more of users to tamper with POST data than with GET Not a lot more. Simply save the slightly modified form on a webserver you have access to (hidden field) -- or better create php code that generate the form OK, aunt Annie cant do that, but she wouldnt ever thougt about tampering with html forms ;-) check whether the referer is from your own site, that will also make it a lot harder. Be carefull, the refer(r)er is _not_ something reliable at all (I consider you can throw away many --20%?-- of them). 1. It can be faked (a little more difficult than simply creating custom html and using a std browser). 2. This can disallow clients from accessing your site. Because of some firewall, anonymiser, adaware-like tools, etc that remove the referer field, by example. More and more people do this to protect their privacy or for security reasons. I think this will become default behaviour in years to come. NB The referer is an OPTIONAL http field (see rfc2616) 3. It denies direct access to the page via bookmarks or typed-in uris (no referer generally sent in these cases) As many said, just dont rely on unchecked input data: check it with a 'white list' (use regex by example).

If by "after a page is submitted" you mean "after a page is requested", then you can already be assured that the user cannot tamper with data. Now, don't be mislead by this, but all it means is that if you have code such as: Then, regardless of whether register_globals is enabled or what the user may do, you can feel comfortable that this script will output "bar". Once your script begins execution, the user's request has been received, and the user cannot take any further action that will manipulate data. Of course, the user can try again on the next request. > I noticed when I use the hidden html input tag with hidden data in it > then when I click the submit button to submit the webpage, the hidden > data then show up in the URL address.

Yes, but both GET and POST are sent by the user.

Absolutely not. This requires that you validate all data from the client. This means GET data, POST data (which may include file uploads), and cookies are potentially dangerous. Hope that helps.

I wanted to know is is there a way to configure PHP to make it not be affected when the web user tamper with the values in the post string after a webpage is submitted or something. (Further explanation below) I noticed when I use the hidden html input tag with hidden data in it then when I click the submit button to submit the webpage, the hidden data then show up in the URL address. Fine, no problem. But I noticed one problem, I can changed the value in the URL toolbar of the web-browser and get different result on the webpage. I know it is where $_REQUEST[], $_GET, etc. come into play. So, is there a way to keep that $_REQUEST[], $_GET[] data unchanged? Does this require the php.ini configuration or what? I think when you change the FORM tag by adding method="POST" to it is so the form data are send as POST instead of GET. IN the next page you will then find the form element values in the $_POST array. It takes a lot more of users to tamper with POST data than with GET data. However you can never trust anything coming over the net and there are ways to fake POST data. In the post-form page check whether the referer is from your own site, that will also make it a lot harder.

I was only suggesting that rather than try to perfect your own parser, you'd be better off spending that time getting comfortable with something that already exists for this purpose. There is too much debugging, testing, optimization and research required to build one that is adequate, and many already exist that probably exceed any home-brew solution. I have not done too much XML parsing in PHP yet, but you might look to PEAR for help with this. I've briefly experimented with the various PEAR XML packages, like XML_Tree and XML_Parser. Take a look: http://pear.php.net/packages.php?catpid=22&catname=XML If you're dealing with poorly formed XML then you've got another problem if you're trying to actually parse it. To simply pull one or two values out of the file, a regex still might be the quickest/dirtiest.. If you do want to move forward testing parsers and stuff, make yourself a valid XML file to test with, so that is not the issue...worry about fixing malformed XML later with the provider or through an intermediate filter.. -- Kelly Hallman //Ultrafancy/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Is there a way to use the strpos() for next string...
Yea, the manual is clear but honestly, don't know what the offset really meant since there is no definition or explaination of how the offset work. All I know the definition of the offset is 'To balance each other out'. Like a weighting scale where one weight is more than other and I would need to add a bit of a weight to the lightest part to offset the other. So, I knew that is not what the manual meant so don't know how exactly does it work since there's no explanation or example of it. But now I understand when I saw your example, so I'll tweak the coding. I'll also have to customize the codes to check to see if the HTML's CDATA is returned or not as well as the XML's CDATA is returned or not. Oh boy!

And the return value of strpos() is also an offset within the string. So, assuming your CDATA segments are nested (which the above seems to imply), then: >$XML_Start = strpos($res_str, "", $HTML_Start); >$XML_End = strpos($res_str, "]]>", $HTML_End+3); If they're not nested, then the search order would need to be different (you need to look for substrings in the order in which they occur in the string as a whole) but the principle is exactly the same.

There isn't > detail information on the php.net website... "The optional offset parameter allows you to specify which character in haystack to start searching. The position returned is still relative to the the beginning of haystack." So if you are trying to find subsequent occurrences of the string, you'd need to make the offset be greater than the last character you checked, or you're going to keep getting the first occurrence. >$XML_Start = (strpos($res_str,"",1); >$XML_End = strpos($res_str,"]]>",2); If you're just trying to pull one bit of data out of a file, you might want to look into regex for this purpose. If you're actually trying to write a parser, I think you might do well to read up on how other parsers work (like, using a stack). Anyway, don't do that, use an existing XML parser.. unless you are on a learning quest.. then, by all means! -- Kelly Hallman //Ultrafancy/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Create a class specifically for that table and it's links.
for example
.yourtable {font-family: Verdana, Arial, Helvetica, sans-serif;font-size:
8pt; color: #ff;}
A.yourtable:link { text-decoration: underline; font-weight: normal; color:
#336699;}
A.yourtable:visited { text-decoration: underline; font-weight: normal;
color: #336699;}
A.yourtable:hover { text-decoration: underline; font-weight: normal; color:
#336699;}
A.yourtable:active { text-decoration: underline; font-weight: normal; color:
#336699;}

Re: [PHP] Is there a way to access all the variables in my script?

Daevid Vincent wrote:
Is there some global array or something that contains all the variable names

Here's the scenario. Like most of you, I do a lot of mySQL db work. So I
tend to use this:
if (mysql_num_rows($result) > 0) {
$row = mysql_fetch_array($result,MYSQL_ASSOC);
while(list($myVariableName,$sqlFieldName)=each($row))
{ $$myVariableName = $sqlFieldName; }
}
So now I have a bunch of variables all named say, $company_name,
$company_id, $company_phone, etc...
What I want to do is make a function that can step through all the $company_
variables and unset them all.
(I imagine I'll just string compare to "company_" and then prefix the result
with $$, then set = "", etc. you get the idea)
I suppose I could re-write all my code and use the $row['company_id'] method
instead then clear $row[] but it would be nice to know if there is a way to
do this 'my way' as well...

Re: [PHP] Is there a way to undo the md5() encryption??
I had it figured out!! Don't need to decrypt it. Instead, I can encrypt the account number by javascript. Grab the unencrypted account number. Put it into two variable, encrypt the first one with PHP and match it by Javascript. If accept then I use the 2nd variable to grab the data from the data and put it into the sessions.

Re: [PHP] Is there a way?
Ok so let me ask one last question..
Which it faster, to run my function and part of the function would be to get
data from a website and break it into variables then make all the html and
variables one new variable for printing
or
Get my data put into variables made global and then in my HTML page use tags
like .
The last one is easier to design with, but may slow things down each time it
has to parse out the PHP tag, no?
