Codeigniter表单验证 - 是否有一种方法来定义多个不同的％s设置错误消息？ [英] Codeigniter Form Validation - Is there a way to define multiple different %s when setting error messages?

问题描述

根据文档，％s将被字段名称替换

Based on the documentation, %s will be replaced by field name when setting error messages.

如果在错误字符串中包含％s，它将替换为
human

If you include %s in your error string, it will be replaced with the "human" name you used for your field when you set your rules.

有一种方法可以在字符串中包含多个％s，并以不同的方式定义它们？

Is there a way to have multiple %s in the string and define them differently?

推荐答案

这是表单验证库中创建错误消息的行：

This is the line in the form validation library that creates the error message:

// Build the error message
$message = sprintf($line, $this->_translate_fieldname($row['label']), $param);

• $ line ：错误消息模板，例如％字段无效


• $ this-> _translate_fieldname（$ row ['label' code>：字段的标签


• $ param ：参数传递验证函数$ c> max_length [5] 会传递5


• $line: The error message template, for example "The % field is invalid"
• $this->_translate_fieldname($row['label']): The field's label
• $param: The parameter passed the the validation function, if any, max_length[5] would pass "5"

验证类为您。如果您需要更大的灵活性，则必须自行准备错误消息 ^{< - 可能有用}

So that's the extent of what the form validation class does for you. If you need more flexibility you'll have to prepare the error message yourself ^{<-- might be useful} beforehand with the extra variables already populated.

通过 core / MY_form_validation.php

It might be interesting to extend the form validation class via core/MY_form_validation.php and work this functionality in. Unfortunately this line is contained in the main function _execute which is very big and messy, and from looking at it now, you'd need to overload some other functions as well. I started to write an example but it actually looks like a chore. You might be better off using:

$this->form_validation->set_message('rule_name', 'Your custom message here');
