Question

I have a form, where a user has to check at least one checkbox before submitting the form. Is there any plugin that can handle this or maybe jquery that can be applied to my form? Unfortunately I’m a total jquery rookie.

The jQuery Validation Plugin can provide this functionality. You can see a demo of how to implement it for requiring a checkbox here.

Basically, once you load the JavaScript file for the validation plugin on your page, you’ll need to initialize the validator for the form you want to validate. The JavaScript to do this will look something like:

$('#form1').validate();

The checkboxes will need to be wrapped in a <fieldset> tag. The validation of the fieldset can then be activated by adding a validate attribute to the input tag for the checkbox. For example:

    <input type="checkbox" validate="required:true" />

The validation will then be triggered when the form’s submit button(s) are clicked.
