Basically...
if I look at the URL it looks like this:
quote:
http://webappdomainname/index.phtml?d=136435&preview=1&t=1259923523
However, if I run this code to show all variables
quote:
# <?php # print '<pre>' . htmlspecialchars(print_r(get_defined_vars(), true)) . '</pre>'; # ?>
I get this:
quote:
[QUERY_STRING] =>
domain=ZnZlcg%3D%3D&company_id=79&contact_id=7226&selected_contact_id=&document_id=136435&document_stack=a:1:{i:0;i:136435;}&u
ser_var_page_name=get+defined+variable&user_var_page_description=&user_var_page_published_date=4th+December+2009&user_var_page_modified_da
te=4th+December+2009&user_var_page_created_by=john+smith&user_var_page_modified_by=john+smith&user_var_custom_icon=&frame_id=244892
I need to get the "contact_id" value from that _server query string and use it in my program.... but I cant for the life of me figure out
how to get it..
The normal method of
quote:
1. <?php 2. 3. echo $_get['contact_id']; 4. 5. ?>
Does not work, because the "contact_id" is not actually in the URL for the $_get to look at....
Any ideas how I can get that variable from the query string rather than from the URL string?

Could it be in the session variables?
ie SESSION['contact_id']
Failing that, i found this example which should help (with a little mod):
quote:
After a fruitless attempt find a built-in function whic did this, I wrote this functions to find out all the variables (well, those I wanted)
in current scope and their values. I believe this is going to be handy in debugging.
<?php
/**
* @desc works out the variables in the current scope(from where function was called).
* Returns an array with variable name as key and vaiable value as value
* @param $varList: variables returned by get_defined_vars() in desired scope.
* $excludeList: variables to be excluded from the list.
* @return array
*/
function getDefinedVars($varList, $excludeList)
{
$temp1 = array_values(array_diff(array_keys($varList), $excludeList));
$temp2 = array();
while (list($key, $value) = each($temp1)) {
global $$value;
$temp2[$value] = $$value;
}
return $temp2;
}
/**
* @desc holds the variable that are to be excluded from the list.
* Add or drop new elements as per your preference.
* @var array
*/
$excludeList = array('GLOBALS', '_FILES', '_COOKIE', '_POST', '_GET',
'excludeList' ;
//some dummy variables; add your own or include a file.
$firstName = 'kailash';
$lastName = 'Badu';
$test = array('Pratistha', 'sanu', 'fuchhi';
//get all variables defined in current scope
$varList = get_defined_vars();
//Time to call the function
print "<pre>";
print_r(getDefinedVars($varList, $excludeList));
print "</pre>";
?>

Can you stick the long Query String through the parse_str() function to get it ?
I'll have a think about it when I get a spare minute.
Cheers,
Tim.

http://www.php.net/manual/en/function.parse-str.php

But im not sure what exactly to try... appreciate any thoughts

I would have expected all the arguments to be in the $argv array, but know there is some issue with having to set something in the php.ini.
if you do this what do you get :
foreach($_SERVER['argv'] as $k=>$v)
echo "$k -> $v \n";

If its a posted form you need to use $_POST["Contract_Id"]
