Laravel Add a new column to existing table in a migration

I can't figure out how to add a new column to my existing database table using the Laravel framework.

I tried to edit the migration file using...

<?php

public function up()
{
    Schema::create('users', function ($table) {
        $table->integer("paid");
    });
}

In terminal, I execute php artisan migrate:install and migrate.

How do I add new columns?

It would be useful if you could include any errors you're getting; what do you expect to happen; and what actually happens?
Great question. There is a lot of migration documentation out there, and it shows you the API and how to create tables the FIRST TIME. Then it all fails as you develop your app more and need to modify your db structure.
You must use php artisan make:migration

To create a migration, you may use the migrate:make command on the Artisan CLI. Use a specific name to avoid clashing with existing models

for Laravel 5+:

php artisan make:migration add_paid_to_users_table --table=users

for Laravel 3:

php artisan migrate:make add_paid_to_users

You then need to use the Schema::table() method (as you're accessing an existing table, not creating a new one). And you can add a column like this:

public function up()
{
    Schema::table('users', function($table) {
        $table->integer('paid');
    });
}

and don't forget to add the rollback option:

public function down()
{
    Schema::table('users', function($table) {
        $table->dropColumn('paid');
    });
}

Then you can run your migrations:

php artisan migrate

This is all well covered in the documentation for both Laravel 4 / Laravel 5:

Schema Builder

Migrations

And for Laravel 3:

Schema Builder

Migrations

Edit:

use $table->integer('paid')->after('whichever_column'); to add this field after specific column.


Just php artisan migrate
Something is wrong. I make "db:make" to make a new migration file. And then i put the Schema::table('users', function($table) { $table->integer('paid'); }); into it. And run "php artisan migrate", but getting Fatal error: Cannot redeclare class Users in /Applications/XAMPP/xamppfiles/htdocs/adsense/application/migrations/2013_05_28_122527_users.php on line 3
Creating migrations is also covered in the documentation. You should give it a more specific name, like "add_paid_to_users", this way it will not clash with your model clash.
Seems like any Laravel 3 doc URL is redirecting to the Laravel 4 docs. Here are the links to the 3 doc for schema builder and migrations
As of Laravel 5, this command would now be php artisan make:migration add_paid_to_users

I'll add on to mike3875's answer for future readers using Laravel 5.1 and onward.

To make things quicker, you can use the flag "--table" like this:

php artisan make:migration add_paid_to_users --table="users"

This will add the up and down method content automatically:

/**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::table('users', function (Blueprint $table) {
        //
    });
}

Similarily, you can use the --create["table_name"] option when creating new migrations which will add more boilerplate to your migrations. Small point, but helpful when doing loads of them!


That was not the case in Laravel 5.0, Blueprint was added in Laravel 5.1. Just a point of clarification is all.
@PhillSparks You're right, thank you for catching my mistake. I've updated to clarify the version in which this can be used.

laravel 5.6 and above

in case you want to add new column as a FOREIGN KEY to an existing table.

Create a new migration by executing this command : make:migration

Example :

php artisan make:migration add_store_id_to_users_table --table=users

In database/migrations folder you have new migration file, something like :

2018_08_08_093431_add_store_id_to_users_table.php (see the comments)

<?php

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

class AddStoreIdToUsersTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::table('users', function (Blueprint $table) {

            // 1. Create new column
            // You probably want to make the new column nullable
            $table->integer('store_id')->unsigned()->nullable()->after('password');

            // 2. Create foreign key constraints
            $table->foreign('store_id')->references('id')->on('stores')->onDelete('SET NULL');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::table('users', function (Blueprint $table) {

            // 1. Drop foreign key constraints
            $table->dropForeign(['store_id']);

            // 2. Drop the column
            $table->dropColumn('store_id');
        });
    }
}

After that run the command :

php artisan migrate

In case you want to undo the last migration for any reason, run this command :

php artisan migrate:rollback

You can find more information about migrations in the docs


The rollback wont work like this. For rollback to work, $table->dropForeign('posts_store_id_foreign'); $table->dropColumn('store_id');

If you're using Laravel 5, the command would be;

php artisan make:migration add_paid_to_users

All of the commands for making things (controllers, models, migrations etc) have been moved under the make: command.

php artisan migrate is still the same though.

In Laravel 8

php artisan make:migration add_columnname_to_tablename_table --table=tablename

then after creating migration in

public function up()
    {
        Schema::table('users', function (Blueprint $table) {

            // 1. Create new column
            $table->datatype('column_name')->nullable();
        });
    }
public function down()
    {
        Schema::table('users', function (Blueprint $table) {

            // 1. Create new column
            $table->dropColumn('column_name');
        });
    }

then run

php artisan migrate

if you face error then rename the migration name with the date before the table created and then run again php artisan migrate


Can we create seeder for the new col?

You can add new columns within the initial Schema::create method like this:

Schema::create('users', function($table) {
    $table->integer("paied");
    $table->string("title");
    $table->text("description");
    $table->timestamps();
});

If you have already created a table you can add additional columns to that table by creating a new migration and using the Schema::table method:

Schema::table('users', function($table) {
    $table->string("title");
    $table->text("description");
    $table->timestamps();
});

The documentation is fairly thorough about this, and hasn't changed too much from version 3 to version 4.


Something is wrong. I make "db:make" to make a new migration file. And then i put the Schema::table('users', function($table) { $table->integer('paid'); }); into it. And run "php artisan migrate", but getting Fatal error: Cannot redeclare class Users in /Applications/XAMPP/xamppfiles/htdocs/adsense/application/migrations/2013_05_28_122527_users.php on line 3
You should name each of the migrations something unique when creating them. Typically the initial create I'll name create_users_table, then if I'm adding columns: add_email_password_columns_to_users.
yeah as evolve says, surely its better to stick with original laravel design philosophies and only use the "add_" verb at front of each file to keep track of changes. this way its easier to track changes for version control etc because a new add file is created for every iteration. If you just went and kept modifying the "create_" it would be hard to know that x employee, had messed something up by removing an index, or adding a new column etc etc. at least that makes sense in my head! :)

Laravel 7

Create a migration file using cli command: php artisan make:migration add_paid_to_users_table --table=users A file will be created in the migrations folder, open it in an editor. Add to the function up():

Schema::table('users', function (Blueprint $table) {
    // Create new column
    // You probably want to make the new column nullable
    $table->integer('paid')->nullable()->after('status');
}

Add to the function down(), this will run in case migration fails for some reasons: $table->dropColumn('paid'); Run migration using cli command: php artisan migrate

In case you want to add a column to the table to create a foreign key constraint:

In step 3 of the above process, you'll use the following code:

$table->bigInteger('address_id')->unsigned()->nullable()->after('tel_number');

$table->foreign('address_id')->references('id')->on('addresses')->onDelete('SET NULL');

In step 4 of the above process, you'll use the following code:

// 1. Drop foreign key constraints
$table->dropForeign(['address_id']);
// 2. Drop the column
$table->dropColumn('address_id');

I am very new to Laravel. It is supposed to make things easier and I can see that. However, why would I do all of the above if I want to add a column to my table? Why would I not just add it to the sql table directly via phpmyadmin or the mysql CLI? Again I am new. It appears that there will be a lot of one-time code created if I am interpreting these answers correctly.
@MichaelB Well, Laravel recommends to use Migrations to add new tables or fields to current tables or create relations. Why? Because at the time moving to 'Production Environment' (Live website) from 'Development Environment', you don't have to create all those tables and relations in database by your own. You just need to upload the files to server, update .env file and run the migration command. Laravel will create the tables with relations for you.

this things is worked on laravel 5.1.

first, on your terminal execute this code

php artisan make:migration add_paid_to_users --table=users

after that go to your project directory and expand directory database - migration and edit file add_paid_to_users.php, add this code

public function up()
{
    Schema::table('users', function (Blueprint $table) {
         $table->string('paid'); //just add this line
    });
}

after that go back to your terminal and execute this command

php artisan migrate

hope this help.

First rollback your previous migration

php artisan migrate:rollback

After that, you can modify your existing migration file (add new , rename or delete columns) then Re-Run your migration file

php artisan migrate

Llanilek

WARNING this is a destructive action. If you use this ensure you back up your database first

you can simply modify your existing migration file, for example adding a column in your table, and then in your terminal typing :

$ php artisan migrate:refresh

Refresh will empty the table
This is incredibly dangerous - if some people have the run the old version, some will have the new, and chaos will ensue. In Liquibase, if you edit a file, it will fail unless you explicitly put in exceptions to allow it, and you can only do this in very few cases. E.g. if you make a column not-null when some database already have null data in them, it will break.
It would be better, if you edit your answer and mention that it would empty your table, it would be better.
Note: This command will clean entire databases tables, if you want to use it, then backup your database first

Add column to your migration file and run this command.

php artisan migrate:refresh --path=/database/migrations/your_file_name.php

First you have to create a migration, you can use the migrate:make command on the laravel artisan CLI.Old laravel version like laravel 4 you may use this command for Laravel 4:

php artisan migrate:make add_paid_to_users

And for laravel 5 version

for Laravel 5+:

php artisan make:migration add_paid_to_users_table --table=users

Then you need to use the Schema::table() . And you have to add the column:

public function up()

{

    Schema::table('users', function($table) {

        $table->integer('paid');

    });

}

Although a migration file is best practice as others have mentioned, in a pinch you can also add a column with tinker.

$ php artisan tinker

Here's an example one-liner for the terminal:

Schema::table('users', function(\Illuminate\Database\Schema\Blueprint $table){ $table->integer('paid'); })

(Here it is formatted for readability)

Schema::table('users', function(\Illuminate\Database\Schema\Blueprint $table){ 
    $table->integer('paid'); 
});

If you don't want to split the blueprint(schema) into two migration file then the best thing you can do is drop the table from the database and then rename the migration file's last number and do

php artisan migrate

This helps you to protect the data of other tables.

Run this command: php artisan migrate:fresh --seed it will drop the table and re add it updating all the columns adding to the database


In a production environment, you don't want to refresh tables just to add a new column.
V
VANITA CHAUDHARI

What you can do is Like,

Schema::create('users', function ($table) { $table->integer("paid"); });

After Writing this write command php artisan migrate or php artisan refresh What i personally prefer is to refresh rather than fresh migration because if you do fresh migrate it will remove all the data refresh will not.

but only exception is if you do refresh and if you have any foreign key in table so it will not going to re-establish the relationship so you will get error like,

Cannot add foreign key constrain

If none of the solve worked, you might have recreated the migration file then added a new column and tried to run php artisan migrate to update the old table which will try to create that table but the table already exists so it gives an error. To solve that rename the migration file as previously named (started with a date), then add new column run php artisan migrate that will actually update the old one instead of create, solved my problem.
