[Resolved] Passing $_GET variables into an href

tomandhannah

I found the following function at the PHP Manual web site. It works great. It grabs the $_GET variables from the current page and prints it out. in the format of ?variable1=value&variable2=value

But I need to modify it to NOT include some variables. For instance, I have a variable called 'message' that I do not want this function to print. I also have a variable called 'action' that I'd like to change to a different name when printed.

Anyone have any ideas? I've messed around with it a bunch, but only end up making it way more complicated.

$variables = httpimplode(@$_GET);

function httpimplode($aryInput, $quma = true) {
    if (is_array($aryInput) && count($aryInput)>0) {
      if ($quma == true) {
         $result = '?';
      } else {
         $result = '';
      }
      foreach ($aryInput as $key=>$value) {
        if (strlen($result)>1) {
           $result .= '&';
        }
         $result .= urlencode($key) . '=' . urlencode($value);
      }
    } else {
       $result = '';
    }
    return $result;
   }

<?php
$variables = httpimplode(@$_GET,array('message'));

function httpimplode($aryInput,$ignores, $quma = true) {
    if (is_array($aryInput) && count($aryInput)>0) {
      if ($quma == true) {
         $result = '?';
      } else {
         $result = '';
      }
      foreach ($aryInput as $key=>$value) {
        if(!in_array($key,$ignores)) {
          if (strlen($result)>1) {
             $result .= '&';
          }
           $result .= urlencode($key) . '=' . urlencode($value);
         }
      }
    } else {
       $result = '';
    }
    return $result;
   }

Wow! I knew there'd be a simple solution. Thanks a bunch. But what about if I wanted it to change the $_GET variable 'action' to print as 'place'?

In other words, if the url has:
file.php?id=6&active=1&action=nothing$message=5

I want it to print as:
?id=6&active=1&place=nothing

Can be done without much difficulty but it will start getting messy if you go puting special cases in everwhere. You could have another parameter with an array of the form array('search key','replace key','replace var') then if you come across a var in the GET array with a key 'search key' you can replace it with an element 'replace key' with the value 'replace value' (you could have a special name for replace with the original value)
