Form with multiple rows/entity in Symfony

Question

I am using Symfony 6 and created an entity for global options and so the sql table has only 3 columns : name, label and value

In order to store global info about my app. Like this.

id	name	label	value
1	maintenance	Set the app in maintenance	0
2	allow_comments	Allow comments for products	1

How can I make a form which contains every elements of the table ?

I would like the result to be like this : Expected form result

Thanks

You are asking a very broad question and I even wonder how you have a web application at all to configure if you can't do a crud for such a simple entity. Despite being simple it involves too much stuff and you should learn from symfony doc and come back with more specific questions — Diego D

As you have a table (so it's an entity I guess) CollectionType is a way to go.

use Symfony\Component\Form\Extension\Core\Type\CollectionType;
use Symfony\Component\Form\Extension\Core\Type\EmailType;
// ...

$builder->add('emails', CollectionType::class, [
    // each entry in the array will be an "email" field
    'entry_type' => EmailType::class,
    // these options are passed to each "email" type
    'entry_options' => [
        'attr' => ['class' => 'email-box'],
    ],
]);

As the entry_type you can just pass EntityType.

Thanks for taking the time to read my question. Indeed I have an entity GlobalOption. I couldn't understand how I can apply your example to my needs though. I know this is a simple crud operation, but I am used to process only one row of the table.. Thanks anyway !

@lccsc as the entry_type you can pass EntityType:class. Then in the entry_options you can configure it. Ref: symfony.com/doc/current/reference/forms/types/entity.html
