I can\'t get access to my WP (version3.4.2) admin. It says as mentioned above
Fatal error: Cannot re-assign auto-global variable _POST in /home/xxx/p
Since PHP 5.4, you cannot use a superglobal as the parameter to a function
$_POST is globally accessible. So you don't have to pass to your function.
http://php.net/manual/en/language.variables.superglobals.php#112184
This is how your function should look like
function rt_check_sidebar_array(){
if(is_array($_POST)){
$start_unset_count = 0;
foreach($_POST as $key => $value){
if(stristr($key, '_sidebar_name') == TRUE && $value=="") {
unset($_POST[$key]);
$start_unset_count = 1;
}
if($start_unset_count>0){
unset($_POST[$key]);
$start_unset_count++;
}
if($start_unset_count==6){
$start_unset_count = 0;
}
}
}
$newPost == $newPost ? $newPost : $_POST;
return $_POST;
}
