+``` + +### Password strength + +Use this validator to make sure that your user has a strong enough password. Set attributedata-validation-strength to 1, 2 or 3 depending on how strong password you require.
+
+If you want the strength of the password to be displayed while the user types you call displayPasswordStrength() in the end of the form.
+
+```
+
+
+
+
+
+```
+
+### Server side validation
+
+By using this validator you can validate the value given by the user on the server before the form gets submitted. The validation function will send a POST request to the URL declared in data-validation-url. The argument posted to the URL will have the same name as the input being validated.
+
+The form will get the class validating-server-side while the server is being requested.
+
+The response from the validation script must be a JSON formatted object, containing the properties "valid" and "message".
+
+```
+{
+ "valid" : true|false,
+ "message" : "String with text that should be displayed as error message"
+}
+```
+
+#### Form
+
+```
+
+```
+
+#### /validate-input.php
+
+```
+ false,
+ 'message' => 'Post argument "user" is missing.'
+);
+
+if( isset($_POST['user']) ) {
+ $userRepo = new UserRepository( DataStorage::instance() );
+ $user = $userRepo->loadUser( $_POST['user'] );
+
+ if( $user ) {
+ // User name is registered on another account
+ $response = array('valid' => false, 'message' => 'This user name is already registered.');
+ } else {
+ // User name is available
+ $response = array('valid' => true);
+ }
+}
+echo json_encode($response);
+```
+
+**Modifying the server request**
+
+The parameter containing the input value, sent to the server, will by default have the same name as the input. You can however set your own parameter name by using the attribute data-validation-param-name. You can also send along other parameters to the server by using the attribute data-validation-req-params.

+
+## File validators
+
+### File size
+
+This validation is only supported by Internet Explorer 10, Mozilla FireFox v >= 3.6 and any of the later versions of webkit based browsers.
+
+```
+
+
+
+
+
+```
+
+### File type
+
+This validation will fall back on checking the file extension in older browsers. In modern browsers the validation will check that any of the extensions in data-validation-allowing exists in the mime type declaration of the file. This means that data-validation-allowing="pdf" will work in both modern browsers (checking against "application/pdf") and older browsers (checking the file extension ".pdf").

+
+### Image dimension and ratio
+
+Use the validator dimension to check the dimension of an image (jpg, gif or png).
+
+```
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+```
+
+Use the attribute data-validation-ratio to validate that the uploaded image has a certain ratio
+
+```

+```
+
+## Logic
+
+### Validators depending on each other
+
+Use the attributes data-validation-depends-on to configure that an input is optional as long as another input is left without an answer.
+
+```
+
++ Contact me: + +
++ E-mail: + +
+``` + +``` + ++ Country: + +
+ ++ State: + +
+ +... + + + +``` + +### Require only one out of several inputs + +Use the attributedata-validation-optional-if-answered to tell the validator that only one, out of a group of inputs, requires an answer.
