I have a multiple select box.

PHP Code:

<select name="domain[]" multiple="multiple" size="4" class="selectbox">

      <option value="1">Accounting</option>

      <option value="2">Engineering</option>

      <option value="3">Internet</option>

      <option value="4">Sales</option>

</select> 

The user need to select a domain name or more. In PHP I validate this select box as :

PHP Code:

$errormsg = ""



if ($_POST['domain'] == "")

{

    $errormsg .= "No domain name selected<br />";

    $domain    = "";

}

else 

{

    $domain = filterInput($_POST['domain']); // Stripslashes filtering enabled

}



if ($errormsg == "")

{

   foreach($domain as $value)

   {

      print $value;   // I don't receive the value.

   }

}

else

{

    print "error"

} 

I want to get the selected values, for example if someone select "Accounting" and "Engineering" I want to see 1 and 2.

What I need to do ?

Thanks !

It should work, try to use filterInput() not on an array. Use it in the loop instead.

PHP Code:

foreach($domain as $value)

{

     print filterInput($value);   // I don't receive the value.

} 

Edit, if you plan to receive only numeric values here, try using intval() instead.

Thanks Nico ! work great !
Exist a way to check how many domains the user select ?

For example if user select more than 5 domains I want to show an error message.

[Nico]

This should do it.

PHP Code:

if (is_array($domain) AND sizeof($domain) > 5)

{

    exit('You can not select more than 5 domains.');

}



foreach($domain as $value)

{

    print $value;   // I don't receive the value.

}
