问题描述
根据，％s将被字段名称替换
Based on the documentation, %s will be replaced by field name when setting error messages.
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
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');
