Add a new column to existing table in a migration

I really can't figure out how to add a new column to my exiting table in my database using PHP laravel framework.

I tried edit the migration file to

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

$table->integer("paid");


});
}


and in terminal
php artisan migrate:install
and
migrate


How to add new columns?

Answer Source

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 3:

php artisan migrate:make add_paid_to_users

for Laravel 5+:

php artisan make:migration 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 3:

And for Laravel 4 / Laravel 5:

Edit:

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