CakePhp上传验证

Question

I've been trying to get this to work for a bunch of hours, countless googling has not resulted in anything helpful.

I was wondering if there was a way to validate on the variables inside of a form fileinput. So like in a form "upload" I want to make sure that upload[name] is not empty. Could I do this at all with Cakephp's model validation?

Answer 1

There is no way in Cakephp to validate fileinput field.

You can do it by custom validation rules like below example

for view file

<?php
    echo $this->Form->file('image');
    echo $this->Form->error('image');
?>

For model file

<?php
    public $validate = array(
        'image' => array(
            'rule' => array('chkImageExtension'),
            'message' => 'Please Upload Valid Image.'
        )
    );



    public function chkImageExtension($data) {
       $return = true; 

       if($data['image']['name'] != ''){
            $fileData   = pathinfo($data['image']['name']);
            $ext        = $fileData['extension'];
            $allowExtension = array('gif', 'jpeg', 'png', 'jpg');

            if(in_array($ext, $allowExtension)) {
                $return = true; 
            } else {
                $return = false;
            }   
        } else {
            $return = false; 
        }   

        return $return;
    }   
?>
