Symfony 2 validation message

问题

In symfony 2 i have a name filed that i want to validate it and if it contains number I want to show a message. My code is:

//Entity/Product.php
 /**
     * @ORM\Column(name="`name`", type="string", length=255)
     * @Assert\NotBlank()
     * @Assert\NotNull()
     * @Assert\Regex(pattern="/[0-9]/",match=false,message="Your name cannot contain a number")
     */
    protected $name;

But when i write a number in field i see this message Please match the requested format because my field code is like below:

<input type="text" id="mzm_testbundle_category_name" name="mzm_testbundle_category[name]" required="required" maxlength="255" pattern="((?![0-9]).)*">

input tag has a pattern and error that i see is from HTML5. How can i resolsve this problem?

回答1:

The message you see is not coming from the Symfony validator directly. Form framework defines an html5 validation when possible, and the message is indeed coming from the client side validation.

Overriding the client side message

Constraint API's setCustomValidity() can be used to update the client side message.

You can either do it while defining a field:

$builder->add(
    'name',
    'text',
    [
        'attr' => [
            'oninvalid' => "setCustomValidity('Your name cannot contain a number')"
        ]
    ]
));

or in a twig template:

{{ form_row(
       form.name, 
       {
           'attr': {
               'oninvalid': "setCustomValidity('Your name cannot contain a number')"
           } 
       }
 ) }}

Disabling client side validation

You could also disable the html5 validation:

{{ form(form, {'attr': {'novalidate': 'novalidate'}}) }}
