Delete confirmation message in php codeigniter - php

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()
