Question

require_once('classes/class.validation.php');

$array = $_POST['array'];
$pass_profanity = false;
$validation = new Validation;
function check_for_profanity($input){
    if(is_array($input)){
        foreach($input as $row){
            if(is_array($row)){
                check_for_profanity($input);
            } else {
                $pass_profanity = $validation->check_for_profanity($row);
            }
        }
    } else {
        $pass_profanity = $validation->check_for_profanity($input);
        return;
    }
    return;
}
check_for_profanity($array);

But I get the error:

Notice: Undefined variable: validation in
/Library/WebServer/Documents/file.php on line 22

Fatal error: Call to a member function check_for_profanity() on a
non-object in /Library/WebServer/Documents/file.php
on line 2

I can’t figure it out, any thoughts???

Thanks in advance!

Answer 1

You can either gain access to the variable in your function with global:

function check_for_profanity($input){
    global $validation;
    ...
}

Or, the better way would be to retrieve it via a parameter:

function check_for_profanity($input, $validation){
    ...
}

check_for_profanity($array, $validation);
