Get input's data from an invalid form?

Hello everyone,

Here is my login form :

{% form 'customer_login', novalidate: 'novalidate' %}

  
     
     
  

  {% if form.password_needed %}
     
       
       
     

  {% endif %}

{% endform %}

When the form is invalid, I would like to apply special treatment based on the email address which has been entered.

Problem : It seems I can’t access the form’s data.

I tried this, just to display the email address :

{% form 'customer_login', novalidate: 'novalidate' %}

...

{{ form.email | json }}

{% endform %}

But it displays null

Do you know where I could be wrong ?

Thank you for your time ! :wink:
