php - Symfony2 : Two forms in a same page

Question

I've got two forms in a same page.

My problem is when I tried to submit a form, it's like it tried to submit the second form below in the page as well.

As follow, you can find my 2 forms :

public function createSuiviForm() {

    return $form = $this->createFormBuilder(null)
            ->add('numero', 'text', array('label' => 'N° : ',
                'constraints' => array(
                    new AssertNotBlank(array('message' => 'XXXX')),
                    new AssertLength(array('min' => 19, 'max' => 19, 'exactMessage' => 'XXX {{ limit }} XXX')))))
            ->add('xxxx', 'submit')
            ->getForm();
}

public function createModificationForm() {

    return $form = $this->createFormBuilder(null)
            ->add('modification', 'submit', array('label' => 'XXXXXXXXXXXXXXXXXXXX'))
            ->getForm();
}

My second form as only a submit button.

I passed them to my render and display them by using :

<div class="well">
    <form method="post" action='' {{form_enctype(form)}} >
        {{ form_widget(form) }}
        <input type="submit" class="btn btn-primary"/>
    </form>
    <div class='errors'>
        {{ form_errors(form) }}
     </div>
</div>

'form' is the name of my variable to the first form and 'update' for my second form.

When I attempted to submit my second form, I need to click twice and finally I get :

"This form should not contain extra fields."
And all non valid input for the remainding form.

I tried to add validation_group to false but to no avail.

I don't understand why I got this error because my forms are not embedded at all

I hope you will understand...

Answer 1

You have to treat the forms separately:

if('POST' === $request->getMethod()) {
 
    if ($request->request->has('form1name')) {
        // handle the first form  
    }

    if ($request->request->has('form2name')) {
        // handle the second form  
    }
}

This is perfectly explained in Symfony2 Multiple Forms: Different From Embedded Forms (temporarily unavailable - see below)
