Conditional Classes Blade Directives in Laravel - TechvBlogs

New in Laravel 8.51: @class Blade directive to add true/false conditions on whether some CSS class should be added.

 

The @class directive conditionally compiles a CSS class string. The directive accepts an array of classes where the array key contains the class or classes you wish to add, while the value is a boolean expression.

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,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci

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.

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    protected $fillable = [
        'name','description'
    ];
}

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.

routes/web.php

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

$request->validate([
    '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')
->as('subscription')
->withTimestamps();
}
// 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

[Lesson 15] Laravel Blade Foreach ✅ (Laravel 7: Posts Index & Show Views)

Laravel Blade Foreach ✅ Lesson 15

In this lesson, we will pass the posts we created in previous lessons to our posts.index view & our posts.show views.

Using Laravel's @foreach blade directive, we will iterate over each one of our posts and properly output the content for each.

Once we have completed our Posts index view, we will set up each post to on our index page to link to its individual "show" page -- by the end of this lesson we will have completed two of our resourceful routes for our posts we created in earlier lessons.

Dive in, as we check out the power of Laravel Blade Foreach Loops as well as everything else that happens to be incredible about Laravel.
