删除确认短信 php codeigniter

Question

I am trying to get confirmation message before deleting the data, and also I would like to maintain my data in database while deleting them in frontend. here is my (project) index.php view

 <div class="main-sec-contant">
<div class="ProjectsDetails">
    <h2 class="heading">Projects Details</h2>
    <div class="row">
        <div class="col-md-12">
            <table id="table_id" class="display">
                <thead>
                    <tr>
                        <th>Project Name</th>
                        <th>Client Name</th>
                        <th>Company</th>
                        <th>Project Manager</th>
                        <th>Support Staff</th>
                        <th>Status</th>
                        <th>Actions</th>
                    </tr>
                </thead>
                <tbody>
                <?php
                foreach($project as $n)
                {
                    ?>
                    <tr>
                        <td><?php echo $n->project_name;?></td>
                        <td><?php echo $n->client_name;?></td>
                        <td><?php echo $n->company;?></td>
                        <td><a class="pro-circle"><img class="img-sm" src="<?php echo site_url('assets/image/man.png');?>"  data-toggle="tooltip" data-placement="bottom" title="<?php echo $n-> project_manager;?>" data-original-title="Click to deactivate the user"></a>&nbsp&nbsp </td>
                        <td><a class="pro-circle"><img class="img-sm" src="<?php echo site_url('assets/image/man.png');?>" data-toggle="tooltip" data-placement="bottom" title="<?php echo $n-> support_staff;?>" data-original-title="Click to deactivate the user"></a>&nbsp&nbsp 
                        <a class="pro-circle"><img class="img-sm" src="<?php echo site_url('assets/image/man.png');?>"></a>&nbsp&nbsp
                      <a class="pro-circle"><img class="img-sm" src="<?php echo site_url('assets/image/man.png');?>"></a></td>
                        <td><span class="icoact"></span> Active</td>
                        <td><a class="edit" href="<?php echo site_url('admin/project/edit/'.$n->id);?>"><i class="fa fa-pencil-square-o" ></i></a>&nbsp&nbsp<a class="delete"  href="<?php echo site_url('admin/project/delete/'.$n->id);?>"><i class="fa fa-trash-o"></i></a></td>
                    </tr>
                    <?php
                }
                ?>
                </tbody>
            </table>
        </div>
    </div>
</div>

Here is my Project.php controller

public function index ()
{
  $data['company_name'] = $this->project_model->getAllCompanyName();
  $data['project'] = $this->project_model->getProjectDetails();
  $this->load->view('admin/project/index',$data);

}
function delete($id)
 {
   $this->project_model->delete($id); 
   $this->session->set_flashdata ('success','Project Deleted Sucessfully');
   redirect('admin/project/index');

 }

And here is my Project_model.php, delete function

 function getProjectDetails()
 {
//table  (projects)

 $delete_flag=0;
 $data['project'] = $this->db->get_where('projects',array('delete_flag!='=>$delete_flag))->result_array();

}

function getById($id)
 {
   return $this->db->get_where('projects',array('id'=>$id))->row();

 }

function delete($id)
 {
  $delete_flag=0;
  $this->db->where('id',$id)->update('projects',array('delete_flag'=>$delete_flag));
    
 }

Right now I am able to delete the data successfully from both frontend and database, I would appreciate if you can help me how I can get the confirmation message, and also maintain my data in database while deleting them from frontend?

Here is the database table

Answer 1

Delete in Frontend only:

Add a boolean Column "delete_flag" to your project database table and update it to TRUE when delete is clicked in frontend.

Then change your load Method in Project model to only get Projects where delete_flag = 0

Delete Confirmation:

Search for Modal Dialog. You can easily set up a message and confirm button link with a modal Dialog. Maybe you are even using a Template which already provides it.

See an example here: https://www.w3schools.com/howto/howto_css_modals.asp

Answer 2

For Data Delete from Frontend only but not from database:-

You should add a Column name delete_flag int datatype to your project database table and update it to 0 , while deleting the record.

Data Delete Confirmation Alert Message:-

<td><a class="delete"  href="<?php echo site_url('admin/project/delete/'.$n->id);?>"  onclick="return confirm('Are you sure want to Delete this Record?')"><i class="fa fa-trash-o"></i></a></td>

controller Code Project.php:-

function delete($id)
{
   $this->project_model->delete($id); 
   $this->session->set_flashdata ('success','Project Deleted Sucessfully');
   redirect('admin/project/index');

}

Model Code Project_model.php:-

function getProjectDetails()
{
$delete_flag=0;
   $data['project'] = $this->db->get_where('projects',array('delete_flag!='=>$delete_flag))->result_array();
}


    function delete($id)
    {
          $delete_flag=0;
          $this->db->where('id',$id)->update('projects',array('delete_flag'=>$delete_flag));
        
    }

In Your View:-

Show Only records which have delete_flag!=0 by this query in your getProjectDetails()
