Overview
You can validate forms on the site by adding some data-
attributes to various form fields.
Example form code without validation
Take the following form code as an example. Note: This isn't necessarily the standard format of all forms on the site. Some code has been modified simply to be more readable.
<form>
<label>
First Name: <span class="form__required">*</span>
</label>
<input type="text" name="first_name">
<label>
Last Name: <span class="form__required">*</span>
</label>
<input type="text" name="last_name">
<label>
Email: <span class="form__required">*</span>
</label>
<input type="email" name="email">

How to enable form validation
The custom form validation we use on the site will begin working on this form after doing the following:
- Adding
data-validate
to the<form>
tag. - Adding either HTML5/ParsleyJS validation rules to each input or using a valid selector found in the FormValidation.coffee file.
Custom validation rules

<!--
To validate a field group you must wrap the group with a fieldset and then
add the element below as the place where your error message will display.
Note: Only one field is required to have the "required" attribute because they
all share the same name.
-->
<fieldset>
<label><input type="radio" name="favorite_pizza_topping" value="Sausage" required> Sausage</label>
<label><input type="radio" name="favorite_pizza_topping" value="Pepperoni"> Pepperoni</label>
<label><input type="radio" name="favorite_pizza_topping" value="Cheese"> Cheese</label>
<div data-validate-errors></div>
</fieldset>
<label>
