Return False Blocking Multiple Messages

Maybe something like this:

PHP Code:

/**
 * Array to hold error information about multiple uploads.
 * You can check this later to see what errors there were,
 * and not return FALSE inside the upload method.
 */
public $error_stack = array();

public function upload($field = 'userfile') {

    $allowed_extension = explode('|', $this->allowed_types);

    if (empty($this->upload_path)) {
        $this->set_error('upload_path_not_set', 'upload_path_check');

        // Put something in $this->error_stack ...
    } 

    if (!realpath(FCPATH . $this->upload_path)) {
        $this->set_error('upload_path_in_correct', 'location_check');

        // Put something in $this->error_stack ...
    } 

    if (!empty($this->files[$field]['name'][0])){
        foreach ($this->files[$field]['name'] as $key => $value) {

            $this->file_name = $this->files[$field]['name'][$key];

            $get_file_extension = explode('.', $this->files[$field]['name'][$key]);
            $this->get_file_extension_end = strtolower(end($get_file_extension));
                
            $array_1 = array(
                $allowed_extension,
            );

            $array_2 = array(
                $get_file_extension[1],
            );
                
            if (!in_array($array_2, $array_1)) {
                    
                $this->set_error('file_extension_not_allowed', 'extension_check');

                // Put something in $this->error_stack ...
            }

        }

    }

} 


I need to use the return false. Not sure what I should

PHP Code:

$this->error_stack 


There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
