在我的控制器中，我正在设置这样的规则
$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");

但是当我运行表单验证时，我遇到了一些错误
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我做错了什么？
修改
请检查输入名称是否为数组，有多个相同的类型值。所以我需要使用字段名作为数组。
根据codeigniter表单验证，我可以使用包含字段名称作为数组验证表单。
答案 0 :(得分：2)
您的输入由数组组成，而函数max_length和htmlspecialchars需要一个字符串。
如果只有一个值，请使用此类输入：
<input type="text" name="contact_name" value="Dileep" class="t_contact_name">
在数组为a的输入上，必须不要使用上述功能。
