We’ve arbitrarily called these two rules “signup” and “email”.You can name your rules anything you want: An alternate (and more automatic) method of calling a rule group is to name it according to the controller class/method you intend to use it with.Angular JS also holds information about whether they have been touched, or modified, or not.You can use standard HTML5 attributes to validate input, or you can make your own validation functions.In order to get around that problem, you can put such rules as the second element of an array, with the first one being the rule name: All of the native error messages are located in the following language file: system/language/english/form_validation_To set your own global custom message for a rule, you can either extend/override the language file by creating your own in application/language/english/form_validation_(read more about this in the Where rule corresponds to the name of a particular rule, and Error Message is the text you would like displayed.If you’d like to include a field’s “human” name, or the optional parameter some rules allow for (such as max_length), you can add the and tags to your message, respectively: A nice feature of the Form Validation class is that it permits you to store all your validation rules for your entire application in a config file. These groups can either be loaded automatically when a matching controller/method is called, or you can manually call each set as needed.CSS Angular JS Includes Angular JS Animations Angular JS Routing Angular JS Application Angular JS Examples Angular JS Reference Angular JS offers client-side form validation.Angular JS monitors the state of the form and input fields (input, textarea, select), and lets you notify the user about the current state.
``The run()`` method only returns TRUE if it has successfully applied your rules without any of them failing. This method initializes the validation class and loads the form helper and URL helper used by your view files. Based on whether the validation was successful it either presents the form or the success page.
If your callback returns anything other than a boolean TRUE/FALSE it is assumed that the data is your newly processed form data. This is just an example of course, and callbacks aren’t limited to models.
You can use any object/method that accepts the field value as its’ first parameter.
If you submit the form you should simply see the form reload.
That’s because you haven’t set up any validation rules yet.
As shown earlier, the validation array will have this prototype: In order to organize your rules into “sets” requires that you place them into “sub arrays”.
