storing results of a function - previous result overwritten with new result

Posted on 16th Feb 2014 07:03 pm by admin

I have created a function to validate input.

function validate_dimension($value,$name) {

global $errors;
$errors = array();

......validation actions here - this all works fine - if I get an error it is captured like this . . .

$errors[] = "Dimension value missing";

This is all fine and the $error is returned correctly.

So that I can keep the error, I save it as a Session variable

$_SESSION['errors'] = $errors;

HOWEVER the next time I run the function (with the next dimension to be checked) , $_SESSION['errors'] is overwritten and the first error is lost.

I have solved the problem by creating a new array - $all_errors - and adding $errors to $all_errors each time the function is run - but this seems clumsy - I do not need the function as I could just as easily wite a separate line of code for each dimension to be checked.

Can anyone suggest a better way of doing this?
Please?
