Everybody! This is important. In a few days, these forums will be moving over to using the totally sweet Discourse platform. To ensure this migration happens smoothly with no loss of content, these forums are currently in a read-only mode. I do apologize for the inconvenience.

There is never a good time to turn the forums off for an extended period of time, but I promise the new forums will be a billion times better. I'm pretty sure of it.

See you all on the other side in a few days, and if you have any (non-technical) questions, please e-mail me at kirupa@kirupa.com. For technical questions, try to find a tutorial that corresponds to what you are looking for and post in the comments section of that page.

Cheers,

Thread: Error check for $_GET

    Error check for $_GET

    Hi

    I'm really new to PHP, so forgive my lack of proper terminology.

    Basically, I have a php script that is creating a few variables using $_GET. But I was wondering if there is a way to create a default variable when the parameter isn't in the URL to begin with.

    For example if the url was something like: "ww.somewebsite.com/form.php?name=john&surname=smith"

    And php script was something like this:

    Code:
    $name = $_GET['name'];
    $surname = $_GET['surname'];
    
    if ($_GET['company'] == DOESNT-EXIST){
      $company = "no company";
    } else {
      $company = $_GET['company'];
    }
    Any help would be greatly appreciated. Cheers.

    There happens to be a function just for that!

    http://www.php.net/isset

    The code would look like this:

    Code:
    $name = $_GET['name'];
    $surname = $_GET['surname'];
    
    if (!isset($_GET['company'])){
      $company = "no company";
    } else {
      $company = $_GET['company'];
    }

    Aha! Thank you. I eventually found the same answer on another forum.

    Cheers.
