unable to pass the value of the optional parameter in custom command.

protected $signature = 'addcolumn {table_name} {new_column} {column_type} {--default_value}';

i have tried you pass the optional parameter in different ways.

1.php artisan addColumn users new_column varchar(255) testColumn 2. php artisan addColumn users new_column varchar(255) --default_value=testColumn

but I'm getting error this is a error

thank you in advance.

You can try this.

Add = sign after the optional parameter in the code. Without an = sign it takes it as a switch option, which don't take any arguments. If the switch option is present, its value is equal to true and if not then its value is false.

add = sign to accept optional argument.

protected $signature = 'addcolumn {table_name} {new_column} {column_type} {--default_value=}';

In command line:

php artisan addColumn users new_column varchar(255) --default_value=testColumn
