使用codeigniter更新表行并将其保存到数据库中

Question

单击已填充的编辑图标，表格应打开并进行更新

控制器代码

    public function update_menus( $id ) {
    $data = array(
        'menu_title' => $this->input->post('menu_title'),
        'filepath' => $this->input->post('filepath'),
        'description' => $this->input->post('description'),
        'left_content' => $this->input->post('left_content'),
        'right_content' => $this->input->post('right_content'),
        'url_path' => $this->input->post('url_path'),
        'created_date' => date('Y-m-d H:i:s')
    );
    if ($this->login_database->update($id, $data) == TRUE) {
        $this->session->set_flashdata('flash_message', 'updated');
    } else {
        $this->session->set_flashdata('flash_message', 'not_updated');
    }
    $this->load->view('update_menus');
    $data = array();
    $data['menus'] = $this->login_database->get_menus_by_id($id);

    $this->load->view('menu_details', $data);
}

型号代码

public function update($id)
{   
    $data = array(

            'menu_title'=> $this->input->post('menu_title'),
            'filepath' => $this->input->post('filepath'),
            'description' => $this->input->post('description'),
            'left_content' => $this->input->post('left_content'),
            'right_content' => $this->input->post('right_content'),
            'url_path' => $this->input->post('url_path'),
            'created_date' =>date('Y-m-d H:i:s')
            );
    $this->db->where('id',$id);
    $menus = $this->db->update('menu_details', $data);
    return $menus->result();
}

查看代码

     <?php
echo form_open('user_authentication/update_menu_submit');
?><?php foreach ($menus->result() as $row) {
    ?>
    <div class="box-body">

        <div class="form-group">
            <label for="exampleInputEmail1">Menu Title</label>
            <input type="text" name="menu_title" class="form-control" id="exampleInputTitle" placeholder="Enter Menu Title">
        </div>
        <div class="form-group">
            <label for="exampleInputPassword1">Menu Url</label>
            <input type="text" name="url_path" class="form-control" id="exampleInputurl" placeholder="Enter File Path">
        </div>
        <div class="form-group">
            <label for="exampleInputFile">Upload Image</label>
            <input type="file" name="filepath" id="exampleInputFile">
        </div>
        <div class="form-group">
            <label for="exampleInputDesc">Description</label>
            <textarea id="editor4" name="description"  rows="10" cols="80" placeholder="Enter Description"></textarea>
        </div>
        <div class="form-group">
            <label for="exampleInputcontl">Left Content</label>
            <textarea id="editor5" name="left_content"  rows="10" cols="80" placeholder="Enter Left Content"></textarea>
        </div>
        <div class="form-group">
            <label for="exampleInputcontr">Right Content</label>
            <textarea id="editor3" name="right_content"  rows="10" cols="80" placeholder="Enter Right Content"></textarea>
        </div>
        <div class="box-footer">
            <button type="submit" class="btn btn-primary">Submit</button>
        </div>
    </div>
    <?php
}
echo form_close();
?>
</div>

一旦单击编辑操作，它应该重定向到查看页面并打开填写的表格，其显示错误如

您可以使用以下命令检查生成的查询吗： $ this- db- last_query（）;

$data = array(

        'menu_title'=> $this->input->post('menu_title'),
        'filepath' => $this->input->post('filepath'),
        'description' => $this->input->post('description'),
        'left_content' => $this->input->post('left_content'),
        'right_content' => $this->input->post('right_content'),
        'url_path' => $this->input->post('url_path'),
        'created_date' =>date('Y-m-d H:i:s')
        );
$this->db->where('id',$id);
$menus = $this->db->update('menu_details', $data);
$this->db->last_query();

在您的php admin中检查生成的查询。

返回$ menus-> result（）; 需要吗？
