Form variables analizer [Help =P]

[Lautarox]

Im writting an "auto-check and correct form" in a function, but I have a really difficult problem i can't figure out how to do it, take a look.

 

      function validate ($method, $a_items) {
                if ($method == POST) {
                   foreach ($a_items as $value) {
                           $metodo = $_POST['"$value"'];
                           if ($metodo == "") {
                              echo('Faltan campos por rellenar');
                           }
                           else {
                           $metodo = addslashes(trim($metodo));
                           $_POST[''.$value.''] = $metodo;
                           }
                   }
                }
                else {
                  if ($method == GET) {
                    foreach ($a_items as $value) {
                            $metodo = '$_GET['.$value.']';
                            if ($metodo == "") {
                               die('Faltan campos por rellenar');
                            }
                            else {
                            $metodo = addslashes(trim($metodo));
                            }
                    }
                   }                                    
                 }
       }

 

The problem it's here

$metodo = $_POST['"$value"'];

and here too

$metodo = '$_GET['.$value.']';

how can i get $metodo to be the same post value as each post variable in the foreach?

Thanks =P

it sould be $_POST["$value"] or $_POST[$value]

both above cases would not generate error but it would not return the result you wanted.

I read about this in the php web, it treams the value as i want =P, but why does it assings the arrays values to value if key has already taken it?

And why key has two $?

 

<?php
  foreach ($_POST as $key => $value) {
    $$key = addslashes(trim($value));
  }
?>
