PHP Generic check of URL values

[Lionelandre]

Hi,

I am looking to write a PHP function that would read the URL and verify that none of the values are blank. Now, granted, I could do this manually for each occurence, but I can have my usrl like this:

http://www.somesite.com/index.php3?var1=val1

or like so:

http://www.somesite.com/index.php3?R...t=Submit+Query

I'm sure a genius out there has written a function out there that I can reuse, right ? :)

Thanks a lot, guys.

Lionel

function check_blank($get)
{

  if(is_array($get))
     {
       foreach($get as $key=>$value)
        {
          if(!isset($value))
             {
                $error.=$key .' has no value
';
             }
        }
      }
   if($error)
     {
       $error =  'ERROR: an error has occured
'.$error;
       return $error;
      }
}

useage would be
echo get_blank($_GET);

or an array that you would want to check. Only thing is this will fail if the value they entered is 0

Very cool.

I figure I could use

if ($value != ""){
.....
}

in lieu of

if(!isset($value)) {
...
}

As you can tell, I'm just getting started and I'm learning as I'm doing!

Thanksmuch!

no problem.. glad I could help

i'd do this:

function blankChecker() {

if($_POST['name'] == '' ||
$_POST['address'] == '') {

return 'Error: Do not leave fields blank.'
}
}

Your suggestion is way cool. More efficient, I must say. :)
