FOSUser Bundle Adding PlaceHolder to form element

问题

I understand that when you are overriding FOSUser Bundle Forms, you follow this structure;

{{ form_widget(form.plainPassword.first, { 'attr': {'class': 'myformclass'} }) }}

I also want to add PlaceHolder option to my form element.. How can i do that?

so it will look like something like this;

<input class="myformclass" placeholder="Password" type="password" id="password" name="_password" required="required" />

回答1:

{{ form_widget(form.plainPassword.first, { 'attr': {'class': 'myformclass', 'placeholder': 'Password', 'id': password'}}) }}

Field name depends on your form name

it will like be named this for fosuser bundle register form

fos_user_registration_form[plainPassword][password]

the id will be

fos_user_registration_form_plainPassword_password

You can override "id" like written in my example

Required and name options are defined in the form class

回答2:

You can use the placeholder attribute.

METHOD 1: Twig

{{ form_widget(form.plainPassword.first, { 'attr': {'placeholder': 'enter your password'} }) }}

METHOD 2: Form Builder

$builder
    ->add('plainPassword', null , array(
        'attr'=> 
            array('placeholder'=>'enter your password')
        )
    );
