Validators

NotBlankIf

This validator checks if value is not blank like a standard NotBlank Symfony validator, but also allows define the condition when the NotBlank validation should be performed using Symfony Expression Language.

Example usage

use SecIT\ValidationBundle\Validator\Constraints as SecITAssert;

// ...

/**
 * @SecITAssert\NotBlankIf("this.isSuperUser")
 */

Parameters

Parameter Type Default Description
expression string empty array The expression that will be evaluated. If the expression evaluates to a false value (using ==, not ===), not blank validation won't be performed)
values array empty array The values of the custom variables used in the expression. Values can be of any type (numeric, boolean, strings, null, etc.)

FileExtension

This validator checks if file has valid file extension.

Example usage

use SecIT\ValidationBundle\Validator\Constraints as SecITAssert;

// ...

/**
 * @SecITAssert\FileExtension({"jpg", "jpeg", "png"})
 */
use SecIT\ValidationBundle\Validator\Constraints as SecITAssert;

// ...

/**
 * @SecITAssert\FileExtension(disallowedExtensions={"php", "exe", "com"})
 */

Parameters

Parameter Type Default Description
validExtensions array empty array Allowed/valid file extensions list
disallowedExtensions array empty array Disallowed/invalid file extensions list
matchCase bool false Enable/disable verifying the file extension case

Caution! It's highly recommended to use this validator together with native Symfony File/Image validator.

use SecIT\ValidationBundle\Validator\Constraints as SecITAssert;
use Symfony\Component\Validator\Constraints as Assert;

// ...

/**
 * @Assert\Image(
 *      maxSize="2M",
 *      mimeTypes={"image/jpg", "image/jpeg", "image/png"}
 * )
 *
 * @SecITAssert\FileExtension({"jpg", "jpeg", "png"})
 */
 private $file;

CollectionOfUniqueElements

Parameters

Parameter Type Default Description

customNormalizationFunction null or callable null Custom normalization function
use SecIT\ValidationBundle\Validator\Constraints as SecITAssert;

// ...

/**
 * @SecITAssert\CollectionOfUniqueElements()
 */

            'entry_type' => FileType::class,
            'allow_add' => true,
            'constraints' => [
