desibhupi · 08-25-2006, 04:41 AM

Hello every body

I want to filter all the $_POST variables thru a functiion and want to return the filtered keys along with their values.

below is the sinppet that what i need actually.

PHP Code:

  $field = $_POST;          // all the POST fields

 
$filtered = filter($field);

 
$field1 = $filtered['field1'];

$fieldn = $filtered['fieldn'];     // and so on

i want you guys to please give me hint for making the filter() function;

PHP Code:

  function filter($array){

     $search_for = "what you want to filter by";

     $i=1;

     $output = array();

 
     foreach($array as $array_value){

          if(eregi($search_for,$array_value)){

               $output['value'.$i] = $array_value;

          }

          $i++;

     }

     return $output;

}

havent tested it, but it should work.

I would probably tweak that code:

Code:

     foreach($array as $key => $array_value){
          if(eregi($search_for,$array_value)){
               $output[$key] = $array_value;
          }
     }

That way the returned filtered array has the same keys as the source.
