    Useful variable testing function

    This is a function I use to test for POST variables which have been passed to my scripts.

    It can be modified easily to do the same for variable passed by the GET method, cookies and uploaded files.

    Its nothing exciting but saves on typing. Feel free to use.
    PHP Code:
    /* this function tests for the presence of HTTP post variables passed to the current script
       it takes a list containing a variable number of arguments pertaining to the variable name
       as set in the name attribute of the form input tags

       if all variables passed as arguments are set - the function returns true
       if any variables are not set the function returns false

       this function is very similar to the isset() function - but saves having to write $_POST
       for each variable you want to test
     */
    function posted () {
        
    $arglist func_get_args ();
        
        foreach (
    $arglist as $arg)
            if (! isset (
    $_POST[$arg])) return false;
            
        return 
    true;

    I can see how that can come in handy and I'll probably use it. Thanks for the idea, visualAd.
