Codeigniter Flash数据模态窗口中的消息：已编辑

标签： php codeigniter bootstrap-modal

我有一个查看页面 company_view ，它显示了大学的所有信息，有自己的控制器 company.php ，可以通过模型从数据库中获取结果。< / p>

在此页面中添加了一个模态表单，用户输入其详细信息并将该数据发送到数据库。 换句话说，自定义注册表单。

http://startcodeigniter.blogspot.in/2015/12/create-simple-contact-form-in.html

但是上面的形式是在一个模态中。

插入过程成功但我希望成功消息显示在模态本身，它重定向到另一个页面=＆gt; （提交表单后，新的控制器页面 contactform / index ）。 通过一些解决方案来修复它，但似乎没有任何结果。

是否有任何AJAX方式将数据提交给控制器，以防止重定向？ 一直在寻找类似的AJAX例子，但仍然没有运气。

我在寻找的是当用户提交数据时，模态显示数据在没有重定向的情况下提交。

任何帮助/主管都会对我有所帮助！

更新了视图 - company_view.php

我使用过一种非正统的方法。

将你的模态放在你的html页面中，你的flashdata就像。

 <div class="modal fade" id="messageModal" role="dialog">
 <?php echo $this->session->flashdata('msg'); ?> 
</div>

然后在脚本标记中加载该模式，如果设置了flashdata 

<?php if(!empty($this->session->flashdata('msg')) { ?>
 <script>
    $(window).on('load',function(){
       $('#messageModal').modal('show');
    });
 </script>
 <?php } ?>

这可能不是最佳答案。但绝对是一种方法。 欢迎/欢迎所有建议或改进

@Zeehan Akhtar Mohammed在这里回答。当用户在表单中输入详细信息并单击提交时，数据将插入到数据库中，$this->session->set_flashdata()成功消息以模态显示。正如您所说

注意您可以在配置文件夹中的AUTOLOAD.PHP页面添加帮助和库，但是显示我添加__construct方法##
