Symfony validate telephone in form field

Question

I have Symfony 2.6 and form for Personal Information in form field telephone, like rhis

+38 (918) 280-1594

and if developer write "_" or more digits, space. How in action I check this ? Like developer write

+38 (918) 2 801_594

And I set in DB

+38(918)2801594

what are the processes and decisions or bundles to solve this problem?

->add('telephone', null, array('label' => 'Telephone', 'max_length' => 255, 'required' => false));

$builder->get('telephone')->addModelTransformer(new CallbackTransformer(
    // transform <br/> to \n so the textarea reads easier
    function ($originalDescription) {
        return preg_replace('/[^0-9()]+/', "", $originalDescription);
    },
    function ($submittedDescription) {
        // remove most HTML tags (but not br,p)
        $cleaned = strip_tags($submittedDescription, '<br><br/><p>');
        // transform any \n to real <br/>
        return str_replace("\n", '<br/>', $cleaned);
    }
));

But how it works? I write telephone 65454### and this "#" write in my DB this is wrong. Why I not Understand? And I need determine the number of digits (12 digits). Maybe Example please.

I post +30632666$$# and in DB set this +30632666$$# but in form visible this 30632666 this is exactly I need in my DB, I need set in database correct telephone and limit 13 chars - one "+" and 12 - digital

Answer 1

After installing the MisdPhoneNumberBundle , you can use the bundle's validator:

use Doctrine\ORM\Mapping as ORM;
use Misd\PhoneNumberBundle\Validator\Constraints as MisdAssert;

/**
 * @ORM\Entity
 * @ORM\Table
 */
class Entity
{

  // ...

  /**
   * @ORM\Column(type="string", length=50)
   * @MisdAssert\PhoneNumber()
   */
  private $phone;
}

您应该使用MisdPhoneNumberBundle ，它为您提供有关电话号码和Symfony的所有信息。

I do not understand by what mean you're trying to replace # by something else. If this is the preg_replace call, it is not amazing that it does not work, as you're looking for a string that looks like:

#<br, (optional spaces), (Maybe /), >#

If you want to replace <br/> by \\n like the comment says, you need to put this pattern:

/<br\s*\/?\s*>/i

Note the / at start and end to limit the pattern, and i at the end means any case match.

If you want to replace # , spaces and _ , I think that the best would be to replace any character which is not a number of ( , ) . In which case this regexp should work (not tested):

preg_replace('/[^0-9()]+/', "", $originalDescription);

Which means: replace any sequence of 1 or more character which NOT (because of '^') in 0-9 , ( or ) by an empty string.

您应该使用Symfony Data Transformers执行此任务。
