下拉列表不能在codeigniter中工作 [英] Dropdown required not working in codeigniter

问题描述

我想让邮件是必填字段，但不知何故它不起作用，我错过了什么？

I want to make the mail is field required, but somehow its not working, am i missing something?

<div class="col-md-5 ">
  <div class="control-group form-group">
    <label class="control-label">
      Escalation Email Ids
    </label>
    <div class="controls">
      <?php $options=a rray(); if(count($useridsoptions)){ foreach($useridsoptions as $key=>$val){ $options[$key]=$val; } } echo form_dropdown('esc_users[]', $options, explode(",",$row->esc_users),'id="esc_users" class="form-control function col-md-12 select2", reqired="required" multiple'); ?>
    </div>
  </div>
</div>

推荐答案

注意到代码中的几个问题。
必填& array 拼写错误而且在 form_dropdown（）函数

Noticed several issues in code. required & array spelling is wrong moreover wrong syntax used in last params in form_dropdown() function

试试这个

<div class="col-md-5 ">
  <div class="control-group form-group">
    <label class="control-label">
      Escalation Email Ids
    </label>
    <div class="controls">
      <?php $options=array(); if(count($useridsoptions)){ foreach($useridsoptions as $key=>$val){ $options[$key]=$val; } } echo form_dropdown('esc_users[]', $options, explode(",",$row->esc_users),'id="esc_users" class="form-control function col-md-12 select2" required="required" multiple'); ?>
    </div>
  </div>
</div>
