when i load a form, i'm taking posts from a previous form using the following code

foreach ($_POST as $id) {
      
   preg_match('/^(\d+)(\w)$/', $id, $m);
   $elems[$m[1]] = $m[2];
}



on the current for, i want it to call its self using php_self and validate that the user has entered in some textboxes, this seems to cause a conflict as when i put

while (list($name,$value) = each($_POST)){
$$name = $value;
if ($value == ""){
      
     $variableName = $name."error";
     $$variableName = true;
        $overallerror = true;
}
}

after the code the post array is empty, does anybody have any suggestions?

The internal pointer of the array advances as you loop through $_POST with the foreach function
The each() function does NOT reset the internal pointer
so after the foreach finishes you need to call

foreach ($_POST as $id) {
     
   preg_match('/^(\d+)(\w)$/', $id, $m);
   $elems[$m[1]] = $m[2];
}

reset($_POST);

or simply use foreach for your second loop that reset the pointer

foreach($_POST as $name=>$value) {
$$name = $value;
if ($value == ""){
     
     $variableName = $name."error";
     $$variableName = true;
        $overallerror = true;
}
}
