I created another row named article_tags because the relationship between the article and tags is belognsToMany so here is the article_tag code

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateArticleTagTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('article_tag', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('article_id');
            $table->integer('tag_id');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('article_tag');
    }
}

Okay here are the steps to follow.

  1. in edit function of controller get all the tags of particular article and pass them to view.

  2. In view check in your for loop of select if that id exists in tags array, if it exists use 'selected' attribute.

    @foreach ($tags as $tag)
              <option value="{{$tag->id}}" {{ in_array($tag->id,$selected_tags)?'selected':''}}> {{$tag->name}}</option>
     @endforeach

im soo late,but what is variable $selected_tags?

anuzpandey's avatar

@rrrr $selected_tags are the tags that a post has. To get $selected_tags:

$selected_tags = array();
foreach ($post->tags as $post_tag) {
     array_push($selected_tags, $post_tag->id);
}

Or the other solution is:

@foreach($tags as $tag)
    <option value="{{ $tag->id }}"
        {{ ($post->tags()->pluck('id')->contains($tag->id)) ? 'selected' : '' }}
    >{{ $tag->id . ' - ' . $tag->name }}</option>
@endforeach
