Creating a single delete method that can delete any number of data from any table dynamically is a great idea while working on backend application.
Generally, Laravel delete method works wonder but it makes your task much easier if you could add a single method that works universally.
In the example below, Users table is used for reference.
Create a method that'll store all the data from the users in a variable so that you can display them in your blade template when a route is requested.
// Route Example Route::get('users','adminController@users'); // Controller Method public function users(){ $data = Users::all(); return view ('allUsers',['data'=>$data]); }
Now, you can create a table in your blade template allUsers.blade.php in this example to display those data in a tabular format. Make sure you wrap them inside a <form> tag.
Here's an example.
<form method="post" action="{{url('multipleDelete')}}"> {{ csrf_field() }} <input type="hidden" name="tablename" value="{{encrypt('users')}}"> <input type="hidden" name="tableid" value="{{encrypt('id')}}"> <table class="table table-striped"> <thead> <tr> <th><input type="checkbox" id="select-all"> Username</th> <th>Email</th> <th>Role</th> </tr> </thead> <tbody> @if(count($data) > 0) @foreach ($data as $user) <tr> <td> <input type="checkbox" name="select-data[]" value="{{$user->id}}">{{$user->name}}</a> </td> <td>{{$user->email}}</td> <td>{{$user->role}}</td> </tr> @endforeach @else <tr> <td colspan="3">No Categories found !!!</td> </tr> @endif </tbody> </table> <button>Delete Users</button> </form>
Sending name and id of the table helps you delete data dynamically.
A checkbox with name select-data[ ] is added to each row so that any number desired data can be selected. A checkbox is added on the table head too which will make all the data selected at once.
Here's the javascript code that will force all the checkbox get selected on a single click on the checkbox on the table head.
<script> $('#select-all').click(function(event) { if(this.checked) { $(':checkbox').each(function() { this.checked = true; }); }else{ $(':checkbox').each(function() { this.checked = false; }); } }); </script>
Now, define the delete route in your web.php file and create the method in your controller.
Route::post('multipleDelete','adminController@multipleDelete');
Now, you can add the function as shown below or add your own logic wherever needed.
public function multipleDelete(){ // store all input data in $data except the values of csrf token $data = Input::except('_token'); // decrypt the tablename and columnname of data id and store in variables $tbl = decrypt($data['tablename']); $tblid = decrypt($data['tableid']); // check if the data is empty and return message to the user if(empty($data['select-data'])){ session::flash('message','Please Select the data you want to delete !'); return redirect()->back(); } // store all ids sent from the form as array in a variable $ids = $data['select-data']; // run foreach loop and delete each data one by one foreach ($ids as $id){ DB::table("$tbl")->where("$tblid",$id)->delete(); } // display success message to the user session::flash('message','Data deleted sucessfully !'); return redirect()->back(); }
In this way, you can easily create a method to delete any number of data from any table dynamically in Laravel.
Please let everybody know if you have an even better idea to do so.
