Codeigniter 2的自定义表单验证错误消息 [英] Custom form validation error message for Codeigniter 2

问题描述

我有一个名为business_id的下拉菜单。

I have a drop down named "business_id".

<select name="business_id"> 
    <option value="0">Select Business</option> More options... 
</select>

这里有验证规则，用户必须选择一个选项。

Here comes the validation rule, user must select an option.

$this->form_validation->set_rules('business_id', 'Business', 'greater_than[0]');

问题是错误消息说：业务字段必须包含大于0的数字。不是很直观！

Problem being the error message says: The Business field must contain a number greater than 0. Not very intuitive! I want it to say "You must select a business".

我试过：

$this->form_validation->set_message('Business', 'You must select a business');

但CI完成忽略此。

推荐答案

尝试不对默认选择...设置value属性...

Try not setting the value attribute on the default select...

<select name="business_id"> 
    <option value>Select Business</option> More options... 
</select>   

，然后只需使用您的表单验证规则...

and then just using required for your form validation rule...

$this->form_validation->set_rules('business_id', 'Business', 'required'); 

我想你可以尝试编辑你尝试设置消息的方式...

I suppose you could try editing the way that you're trying to set the message also...

$this->form_validation->set_message('business_id', 'You must select a business');
instead of
$this->form_validation->set_message('Business', 'You must select a business');

我不完全确定是否会做这个伎俩。

I'm not entirely sure if that will do the trick though.
