【问题描述】：

我想在成功提交表单时打开模型，但是虽然表单正在提交，但没有弹出模式。

public function insert($data) 
    // Inserting into your table
    // Calling model
    $done = $this->db->insert('sign_up', $data);

    if($done) 
        echo "<script>$('#thankyouModal').modal('show')</script>";
        echo '<div class="modal fade" id="thankyouModal" tabindex="-1" role="dialog">
        <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">Thank you for pre-registering!</h4>
                </div>
                <div class="modal-body">
                    <p>Thanks for getting in touch!</p>                     
                </div>    
            </div>
        </div>
    </div>';
    

我正在尝试使用

在控制器中打开模型

   $data = array(
            'first_name' => $fname,
            'last_name' => $lname,
            'email' => $email,
            'password' => $password
        );
        $this->load->model('modal');
        $this->modal->insert($data);

【参考方案1】：

试试下面的代码；这会工作

public function insert($data) 
    // Inserting into your table
    // Calling model
    $done = $this->db->insert('sign_up', $data);

    // You can do something else here
    if($done) 
?>
        <script>$(document).ready(function()$('#thankyouModal').modal('show'));</script>
        <div class="modal fade" id="thankyouModal" tabindex="-1" role="dialog">
        <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">Thank you for pre-registering!</h4>
                </div>
                <div class="modal-body">
                    <p>Thanks for getting in touch!</p>                     
                </div>    
            </div>
        </div>
    </div>
<?php
    

【参考方案2】：

将modal的代码放在一个view文件中，这样我们就可以在view文件中方便的用javascript调用modal了。 并且你需要在flash data中设置一个变量，这样你就可以检查表单是否被成功插入的条件。 代码如下，希望对你有帮助：

控制器文件：

    public function insert($data) 
    // Inserting into your table
    // Calling model
    $done = $this->db->insert('sign_up', $data);
    // You can do something else here
    if($done) 
      //You can set the message and variable name as per your need.
      $this->session->set_flashdata('inserted','Yes');
      //Redirect to the desired view file
      redirect("controller/anotherfunction_where_view_file_is_loaded");
    

查看文件：

 <div class="modal fade" id="thankyouModal" tabindex="-1" role="dialog">
    <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">Thank you for pre-registering!</h4>
            </div>
            <div class="modal-body">
                <p>Thanks for getting in touch!</p>                     
            </div>    
        </div>
    </div>
</div>

<?php if((isset($this->session->flashdata('inserted'))) && $this->session->flashdata('inserted') != "")  ?>

<script type="text/javascript">

    $(document).ready(function()
      $('#thankyouModal').modal('show');
    );

</script>

<?php  ?>

【参考方案3】：

我得到了答案

控制器

public function insert() 
    $signup_email = $this->input->post('signup_email');
    $signup_password = $this->input->post('signup_password');
    // Checking if everything is there
    if ($fname && $signup_email && $signup_password) 
        $data = array(
              'email' => $signup_email,
              'password' => $signup_password
        );
        if($this->modal->insert($data)) 
             echo "SOME DATA TO BE DISPLAYED IN MODAL";
