Description
Hi guys, thanks for the great work you do on Symfony! Let me show you what brings me here.
My goal is to have a button outside the <form> and </form> tags (for various reasons I would not like to discuss here), html5 allows this if controls outside the tags point to a form with their form attribute. According to the documentation, there is an option called form_attr that You can also set this to true on a root form to automatically set the "form" attribute on all its children.
Nice! I tried, and it failed. The 'form_attr' => true option was set on root form, but it does not give a form="name" attribute for children rendered after the form_end.
EditorshipType:
$builder
->add('entity', EntityType::class, blah blah blah)
->add('request', SubmitType::class, blah blah blah); <-- Button will be outside the form tags
Controller:
$formName = 'form1';
// Set the name
$form = $formFactory->createNamed($formName, EditorshipType::class, $editorshipDecision, [
'attr' => [
// Set the id
'id' => $formName,
],
// Command sub fields to have form = name
'form_attr' => true,
]);
Template:
<tr>
<td>{{ form_start(form) }}{{ form_row(form.entity) }}{{ form_end(form, {'render_rest': false}) }}</td>
<td>{{ form_row(form.request) }}</td>
</tr>
Resulting html:
<tr>
<td>
<form id="form1" name="form1" method="post">
<select id="form1_entity" name="form1[entity]" form="form1" bla bla bla>
<option value="">Choose a seminar...</option>
<option value="3">Blah blah blah</option>
</select>
</form>
</td>
<td>
<button type="submit" id="form1_request" name="form1[request]">Request</button>
</td>
</tr>
Notice my button rendered after the </form> tag does not have the form="form1" attribute. The select rendered between <form> and </form> does.
Of course, as a workaround, I can put the form attribute on the button by its field options, so it's not blocking:
EditorshipType:
$builder
->add('entity', EntityType::class, blah blah blah)
->add('request', SubmitType::class, [
'attr' => ['form' => $builder->getName()],
]);
How to reproduce
See the code above, I made it easy to read.
