    I’m trying to pass the href attributes of two links to php variable using $_GET.
    The code is quite simple, but it’s not working in wordpress:

    <a href="?link=time">Time</a>
<a href="?link=function">Function</a>
<?php
  $childof= 4;
  if(isset($_GET['link'])){
    $link=$_GET['link'];
    if ($link == 'function'){
         $childof= 9;
    }
    elseif ($link == 'time'){
        $childof= 4;
    }
}
?>

    I’ve already installed WordPress Registry plugin, but $_GET is still not working at all. Thanks!

  • I suggest you print out the $_GET array to see what is actually there:

    <a href="?link=time">Time</a>
<a href="?link=function">Function</a>
<?php
print_r('<pre>$_GET:');print_r($_GET);print_r('</pre>');

    That was a good idea! It returns an array:

    $_GET:Array
(
    [page_id] => 8/?link=function
)

    I modified my code like this, it’s working now:

    <?php
  $childof= 4;
  if(isset($_GET[page_id])){
    $link=$_GET[page_id];
    if ($link == '8/?link=function'){
         $childof= 9;
    }
    elseif ($link == '8/?link=time'){
        $childof= 4;
    }
}
?>

    Thank you!
