Question

错误是致命错误：在第5行的C：\ xampp \ htdocs \ payroll \ application \ views \ dtr_timerecord_overtime.php中调用未定义的函数validation_errors（）。

我试图将错误消息发送到其他视图，这没关系，但是当我尝试原始视图时总是出错

查看

Answer 1

好的，这是我的解决方法：

首先，我在我的视图中有这个：

<?php
    echo validation_errors();
?>

它没有用。我一直收到致命错误：调用未定义的函数validation_errors（） ......

然后我这样做了：

<?php
    $this->load->library('form_validation');
    echo validation_errors();
?>

它有效！

Answer 2

您尚未在form_helper中加载application\config\autoload.php，请在自动加载文件中加载form帮助

或在控制器上

$this->load->helper("form");

validation_errors()函数是表单助手。

Answer 3

$this->load->library('form_validation');

在控制器的构造函数中写这个，或者更好地自动加载它。也许，在该方法中，您发布此表单，您不小心没有加载表单验证库

致命错误：调用未定义的函数validation_errors（）
