CodeIgniter Bootstrap form-horizo​​ntal in modal in not working

Question

我的 Web 应用程序使用 CodeIgniter 框架和 Bootstrap 3.0，我试图在我的模式中显示一个表单。我希望labels 与input fields 在同一行，但将form-horizontal 添加到form 或modal-body 似乎没有帮助。

下面的代码段：-

<!-- Add Customer Modal -->
<div class="modal fade" id="addCustomer" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h4 class="modal-title" id="myModalLabel">Add Customer</h4>
      </div>
      <div class="modal-body">
        <?php echo form_open('customer_data/add_customer', ['class'=>'form-horizontal']); ?>

        <?php echo form_label('Name: ', 'name'); ?>
        <?php echo form_input(['name'=>'name', 'id'=>'name', 'class'=>'form-control']); ?>

        <?php echo form_label('Mobile: ', 'mobileNum'); ?>
        <?php echo form_input(['name'=>'mobileNum', 'id'=>'mobileNum', 'class'=>'form-control']); ?>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-warning">Add Customer</button>
      </div>
      <?php echo form_close(); ?>
    </div>
  </div>
</div>

Answer 1

我认为你错过了一些功能

<?php echo form_close(); ?>

或者试试这个：

<!-- Button trigger modal -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#addCustomer">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="addCustomer" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        <!--form horizontal-->

        <?php echo form_open('customer_data/add_customer', array('class'=>'form-horizontal')); ?>

        <?php echo form_label('Name: ', 'name'); ?>
        <?php echo form_input(array('name'=>'name', 'id'=>'name', 'class'=>'form-control')); ?>

        <?php echo form_label('Mobile: ', 'mobileNum'); ?>
        <?php echo form_input(array('name'=>'mobileNum', 'id'=>'mobileNum', 'class'=>'form-control')); ?>
        <?php echo form_close();?>
        <!--end form-->
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>
