How to Set Max String Length in Laravel Migration?

Assume you going to create a blog and there is a field. So you need to set the max string length in your posts table for the body column. So in this example, I will show you how to set the max string length in laravel migration. I will show you laravel migration set string max length. Laravel provides many methods to do that like mediumText() longText() and text() type.

Now assume you need a medium text column then you can set:

<?php

use App\Models\User;
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->mediumText('column');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('posts');
    }
};

 

Now assume you need a simple text column then you can set:

<?php

use App\Models\User;
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->text('column');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('posts');
    }
};

 

Now assume you do not know how much text are you going to post for a single blog post. Then you can use longText():

<?php

use App\Models\User;
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->longText('column');
            $table->timestamps();
        });
    }

    public function down()
    {
        Schema::dropIfExists('posts');
    }
};
