在我的 Controller 中，我设置这样的规则
$this->form_validation->set_rules("contact_name[]","Contact Name","required|max_length[25]|xss_clean|htmlspecialchars");
$this->form_validation->set_rules("contact_title[]","Contact Title","required|max_length[25]|xss_clean|htmlspecialchars");
$this->form_validation->set_rules("contact_main[]","Contact Main Number","required|max_length[45]|xss_clean|htmlspecialchars");
$this->form_validation->set_rules("contact_direct[]","Contact Direct Number","required|max_length[45]|xss_clean|htmlspecialchars");
$this->form_validation->set_rules("contact_cell[]","Contact Cell Number","required|max_length[45]|xss_clean|htmlspecialchars");
$this->form_validation->set_rules("contact_primary","Primary","required|max_length[45]|xss_clean|htmlspecialchars");
$this->form_validation->set_rules("contact_fax[]","Fax","required|max_length[105]|xss_clean|htmlspecialchars");
$this->form_validation->set_rules("contact_email[]","Contact Email ID","required|max_length[105]|xss_clean|htmlspecialchars");
html 是 = >
<input type="text" name="contact_name[]" value="Dileep" class="t_contact_name">
//and some others too as name as array

但是当我运行表单验证时，我收到一些错误
A PHP Error was encountered
Severity: Warning
Message: mb_strlen() expects parameter 1 to be string, array given
Filename: libraries/Form_validation.php
Line Number: 1003
A PHP Error was encountered
Severity: Warning
Message: htmlspecialchars() expects parameter 1 to be string, array given
Filename: libraries/Form_validation.php
Line Number: 619
真正的问题是什么或者我做错了什么？
编辑
请检查输入名称是否为数组，有多个相同类型的值。因此我需要将字段名称用作数组。
根据 codeigniter 表单验证，我可以使用包含字段名称作为数组来验证表单。
最佳答案
您的输入由数组组成，而函数 max_length 和 htmlspecialchars 需要单个字符串。
当只有一个值时，使用这种类型的输入:
<input type="text" name="contact_name" value="Dileep" class="t_contact_name">
在必须使用数组的输入上，请勿使用上述函数。
