CodeIgniter的检查验证已运行且失败 [英] Check validation has run and failed with CodeIgniter

问题描述

如何检查表单验证已运行并失败？使用：

How can I check that form validation has run and failed? Using:

$this->form_validation->run() == FALSE

即使验证未运行，也将运行，即：首次加载表单时（空白状态）。我正在使用形式验证来显示单个错误。但是，我的表格很长，我想在表格顶部显示一条消息，内容如下：

Will run even if the validation hasn't run, ie: when the form is first loaded (blank state). I am using forma validation to show individual errors. However I have quite a long form and I'd like to also show a message at the top of the form, saying something like:

There were errors submitting the form, please check the individual errors below

以下的单个错误

推荐答案

这将执行以下操作：

if (validation_errors()) echo 'There have been errors...';
