globals not available in plugins?

[Foden]

Hi..

Is it not possible to use $_GET[] in plugins, in CMSMS? I have tried some different things now, and it gives me grey hairs..

Further to the above...

I found out that I can do the following :
echo $_GET["page"]; and get the page ID.

But if I try the following :

while (list ($key, $val) = each ($_GET)) {
echo "$key => $val";
}

I don't get any output from the same page..

Also, count($_GET) returns the correct number of parameters, yet.. Still no output for the while loop.

Any clues? Or am I trying the impossible here?

I'm not a coder for real but have you made a look at tag {get_template_vars}?

Maybe helps ...

In Smarty you can access a $_GET['foo'] variable with through the smarty variable:

Code: Select all

{$smarty.get.foo}

This doesn't help.. As I have an existing application written in php, that I'm trying to include into cms. So I can not use smarty tags.

What I need is to use the php super globals like $_GET[], and this is apparently not possible. Why I don't understand? Because the documentation available on php.net, is that it $_GET is ALWAYS available, in all scopes of the php code.

And as my example from before.. I can use $_GET['page'], but I can not use the function

while (list ($key, $val) = each ($_GET)) {
echo "$key => $val";
}


Which will list all the elements in the array $_GET[]

There is something in the array, and I can't figure out why.. Any supercoders?????

Done some more testing..

my user defined tag includes the following code :
include "twg15/index.php";

index.php includes some other files, for filefunctions etc.

at some point in time in index.php I do the following :

$basedir = $install_dir . $basedir;
$cachedir = $install_dir . $cachedir;
$counterdir = $install_dir . $counterdir;
$xmldir = $install_dir . $xmldir;
echo $basedir."".$cachedir."".$counterdir."";

if (!checkCacheDirs()) { // checks if all cache dir are here and set the right umask
    return;
}

The echo outputs dir's as expected.. No problems there, then in checkCacheDirs() I have :
function checkCacheDirs($create_anyway = false)
{
    global $basedir, $cachedir, $counterdir, $xmldir, $install_dir, $store_xml_in_picfolders;
echo $basedir."".$cachedir."".$counterdir."";
}

Now the globals $basedir etc. are empty..

I have googled, I have searched the smarty.php.net site, I have searched php.net I have searched the forum, documentation etc. for cms. But I can't find any indication as to how or why it does work like this!

I would expect that SOMEWHERE there would be a note, either saying "this is not possible" or "to do this, you have to blah blah..."

But NONE! I'm about to give up on this.. Throw in the towel, but I don't like it.. As this is one of the things that make me wonder!

Please, code gurus.. HEEEELP

Seems to work fine overhere (on cmsmadesimple-1.0.2)...
I tried both your while (list ($key, $val) = each ($_GET)) code and the following code in a UDT, both work as expected.

Code: Select all

foreach ($_GET as $index => $value)
{
 echo "$index => $value<br />";
}

Grtz,

And the include trick also works fine overhere...
I created a UDT (named test_tag) containing

Code: Select all

$test = 'test123';
include 'test/test.php';

Then a file 'test/test.php' in the webroot containing

Code: Select all

<?php
echo $test;
?>

Added the UDT to some new content using {test_tag} and voila... test123 on the screen.

So... no idea what's going wrong overthere, but it isn't you

Hmmm.. that is extremely weird / annoying.. 

Just tried the following in a UDT :
echo "test";
while (list ($key, $val) = each ($_GET)) {
echo "$key => $val";

It only prints the "test" part..

I'm also using CMS 1.02 here, and PHP 5.2.0, those of you that has it working, are you using php4? Could it be a setting problem in php?

New info: Tried php 4.4.2 / Apache2 same problem, tried php 4.4.2 / apache 1.3, SAME PROBLEM.. I have tried to mess arround with REGISTER_GLOBALS etc. hmm.. still a problem..

I have seen it working on friends website, running cms.. It must be something in the setup of the server. But I can't figure out where it could be..

more new info...

I have partly success now! At least I can make an UDT that lists the $_GET[] array! Started to mess arround with the php.ini, and copied the php.ini-recomended (recomended for production server) to the php.ini used.. Then it worked (but other sites didn't) I then went through all the settings that was changed from the default setup, and found out that "magic_quotes_gpc off" did the trick! It also messes up all other sites that I host. But now it partly work..

But still included files mess up in global variables...
