Global variable problem

[n00854180t]

I have a functions script that I include into my main script. For some reason one of the global variables I have doesn't seem to hold a value.

If I were to echo $alphaErrMsg inside the function it would echo the value correctly, however if I were to echo it outside the function it would not work.

Here is the function:

global $formComplete;
         global $alphaErrMsg;
function checkFieldAlphaNum($arrOne, $arrTwo){    /* Function takes two arguments, both arrays ($arrTwo should be empty!)
This function checks all the strings in $arrOne and validates them using preg_match, then sets another array for error output. */
    $arrTwo = array();
        $arrayLength = count($arrOne);
            for ($i = 0; $i < $arrayLength; $i++){
                if($arrOne[$i] != "" && !preg_match("/[^a-zA-Z0-9\.\-\ß\ä\Ä\ü\Ü\ö\Ö ]+$/s",$arrOne[$i])){
                    $formComplete = TRUE;
                        $alphaErrMsg = "";
                                } else {
                        $arrTwo[$i] = $i;
                    $formComplete = FALSE;
                    $alphaErrMsg = "<img src='alphabullet.gif'><font face='verdana' size='2'><b>Please complete the fields marked with a red bullet using only alphabetic characters.</b></font>";
                echo "arrayName at[" . $i . "] is: [" . $arrTwo[$i] . "]<br>\n";

        }
    }
return $arrTwo;
}

this is not java... you do not declare you global variables global in the global space...

instead you do it in the fuction that will pull in values and push values out of the function.

move your global declarations inside the function and RTFM and you should be set.
