Php how to delete multiple rows through checkbox using ajax in laravel

First thing, we will need a table and i am creating products table for this example. So run the following query to create table.

CREATE TABLE `products` (
 `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
 `name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
 `description` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
 `created_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
 `updated_at` datetime DEFAULT NULL,

Next, we will need to insert some dummy records in this table that will be deleted.

INSERT INTO `products` (`name`, `description`) VALUES

('Test product 1', 'Product description example1'),

('Test product 2', 'Product description example2'),

('Test product 3', 'Product description example3'),

('Test product 4', 'Product description example4'),

('Test product 5', 'Product description example5');

Now we are redy to create a model corresponding to this products table. Here we will create Product model. So let’s create a model file Product.php file under app directory and put the code below.


namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
    protected $fillable = [

Step 2: Create Route

Now, in this second step we will create some routes to handle the request for this example. So opeen routes/web.php file and copy the routes as given below.


Route::get('product', 'ProductController@index');
Route::delete('product/{id}', ['as'=>'product.destroy','uses'=>'ProductController@destroy']);
Route::delete('delete-multiple-product', ['as'=>'product.multiple-delete','uses'=>'ProductController@deleteMultiple']);

5 Laravel’s Hidden Gems

1. Stop on first validation error

By default, Laravel will check for all validation rules and return a list of errors. But if you want to stop this process after first validation failure, that’s how you can achieve it

    'title' => 'bail|required|unique:posts|max:255',
    'body' => 'required',

2. Find many

Most of us developers have used Eloquent’s method find to search for one specific id, but do you know we can pass multiple ids to find which will return a collection.

// Will return Eloquent Model
$user = User::find(1);
// Will return Eloquent Collection
$users = User::find([1,2,3]);

3. Relationship but with condition

Some times we need to apply where on relationships, instead of calling relationship and then chaining where we can achieve it by following:

// app/Post.php model
public function comments()
    return $this->hasMany(Comment::class);
public function approved_comments()
    return $this->hasMany(Comment::class)->where('approved', 1);

4. Rename pivotal table

In pivot table, if you want to rename pivot to some thing else, this can be done by following code:

public function podcasts() {
return $this->belongsToMany('App\Podcast')
// Then somewhere in Controller...
$podcasts = $user->podcasts();
foreach ($podcasts as $podcast) {
// instead of $podcast->pivot->created_at ...
echo $podcast->subscription->created_at;

#laravel #php #find many laravel #prepare for validation laravel #relationship but with condition laravel #rename pivotal table laravel #stop on first validation error laravel
