How to bypass validation for required input in jQuery validate plugin

Question

How to bypass validation for required input in jQuery validate plugin

As an example, consider the

<input name="surname" id="surname" type="text">

. Sometimes I want to hide this input and make it non-required.

My current workaround is to set a value such as "some value" when hiding the input, and then remove this value with PHP when the form is submitted. This prevents storing the default value in the database.

However, this solution feels more like a workaround than a proper fix. Perhaps a better approach would be to dynamically toggle the required attribute on the field using jQuery validate plugin.

Answer №1

To begin, assign a specific class to the fields you wish to exclude.

$('inputfieldlist').addClass('excludeFields');

Next,

$("#formName").validate({
   ignore: ".excludeFields"
});

This will disregard all elements with the class excludeFields.

For more information, refer to Jquery Validate.

"Perhaps a better approach would be to make a field that is currently marked as required, not required initially, but also provide a solution to add the required validation back when needed."

This answer fulfills your request precisely. You have the flexibility to add and remove rules at your discretion using the .rules() method. (Please note: No changes to existing HTML markup or additional classes are necessary.)

To dynamically add the required rule to id="surname"…

$('#surname').rules('add', {
    required: true
});

To dynamically remove the required rule from id="surname"…

$('#surname').rules('remove', 'required');

Although it may seem unnecessary, as a default behavior, invisible fields are typically disregarded during validation.

Setting up is a breeze. Try it on Jsfiddle by changing 'required' to true to see how it works

rules:{
    optional: {
        required: false
    }
}
