Error setting multiple auth - undefined constant - laravel

Question

My code is:
public function up()
{
Schema::create('users', function (Blueprint $table)
{
$table->increments('id');
$table->string('name');
$table->string('email', 150)->unique();
$table->string('username', 150)->unique();
$table->timestamp('email_verified_at')->nullable();
$table->boolean(‘isAdmin’)->nullable();
$table->string('password', 150); $table->rememberToken();
$table->timestamps(); });
}
Error in cmd
Code / Migrations
Can someone help me?
I already tried to switch the nullable on admin to default(false) but that didn't work

Answer 1

First of all put your code here not image. Change the line to
$table->boolean('isAdmin')->nullable()
you must use quotation.

Answer 2

You are using the wrong quotation inside your code, Use single quotes ' instead of ` on isAdmin
public function up()
{
Schema::create('users', function (Blueprint $table)
{
$table->increments('id');
$table->string('name');
$table->string('email', 150)->unique();
$table->string('username', 150)->unique();
$table->timestamp('email_verified_at')->nullable();
$table->boolean(‘isAdmin’)->nullable();
$table->string('password', 150); $table->rememberToken();
$table->timestamps(); });
}
Change this line
$table->boolean(‘isAdmin’)->nullable();
to
$table->boolean('isAdmin')->nullable();

Answer 3

Please update your migration file like:
public function up() {
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email', 150)->unique();
$table->string('username', 150)->unique();
$table->timestamp('email_verified_at')->nullable();
$table->boolean('isAdmin')->nullable();
$table->string('password', 150);
$table->rememberToken();
$table->timestamps();
});
}
Updated Answer
public function up() {
Schema::create('users', function ($table) {
$table->increments('id');
$table->string('name');
$table->string('email', 150)->unique();
$table->string('username', 150)->unique();
$table->timestamp('email_verified_at')->nullable();
$table->boolean('isAdmin')->default(false);
$table->string('password', 150);
$table->rememberToken();
$table->timestamps();
});
}
Your function like:
public function index() {
return view('home');
}
public function admin() {
return view('admin');
}
Note: Mainly update isAdmin field in migration file
