[SOLVED] Deleting Part of a Query String

[mlacy03]

I have code on my site that hides or shows a table based on what is passed to it through GET.  I haven't been able to completely work out the link to hide and show the table.  The query works, but I cannot get the link to update itself when more than one other variable is passed through GET at the same time:

This is what I have now:[code]

<?php if ($_GET[hide]==="side") {  // if it's supposed to be hidden, show link to show the <td>
?>
<td align="center">
<a href="<?php echo $_SERVER['PHP_SELF'].'?';

/* This is where I am having the most problems */
while (list($var, $val) = each($_GET)) { // I need to get rid of the [hide] variable in $_GET
print "$var=$val&amp;"; }
/*Everything below seems to work */?>  ">

<img src="core.402/img/max.PNG" width="11" height="11" border="0" alt="Maximize" />
</a></td>

<?php
} else { // Because if $_GET[hide] is not defined, it'll do the else, right?
?>
<td><div>
<a href="<?php echo $_SERVER['PATH_TRANSLATED']; 

if ($_SERVER['QUERY_STRING'] != ""){ //if there is a query string, add it on the end as &amp;hide=
echo '?'.$_SERVER['QUERY_STRING'].'&amp;hide=side'; }
else { // if there isn't, make a query string

echo '?hide=side'; } ?> ">
<img src="core.402/img/min.PNG" width="11" height="11" border="0" alt="Minimize" />
</a>

<!-- links go here -->

  </div></td>
<?php } ?>[/code]

Are you asking something like this?
[code]
<?php

$_GET['whatever'];
// use it

$_GET['whatever'] = false;
// cannot use it anymore

?>
[/code]

when [hide] is set, the <td> only shows a link to the original page. I have 2-3 variables being passed on some pages, so i need a way to get rid of the last one, [hide] so the user can see the menu again.  It's a bit like the code for the left nav on the phpfreaks homepage (with the [close_left] and the [open_left]), except I'm using a small image instead of a text link.

[code]
<?php

while (list($var, $val) = each($_GET))
{
if($var != "hide")
{
  print "$var=$val&amp;";
}
}

?>
[/code]
