问题描述

如何在Kohana 3.2中的验证对象上调用 trim 函数?我正在使用:

How can I call the trim function on a validation object in Kohana 3.2? I am using:

$post = Validation::factory($this->request->post());
$post->rule('Email', 'trim');

推荐答案

验证对象从3.2版本开始才可读.在创建Validation对象之前过滤输入，如下所示:

Validation objects are read only as of 3.2. Filter the input before creating the Validation object like so:

$post = array_map('trim', $this->request->post()); // $post[key] = expression; if it is for one specific value

$post = Validation::factory($post);

// set validation rules etc
