Optional Form Fields - One field needs to be required and valid

Hi,

Im using jquery and jquery.validate to validate an online form i have made.
The client has requested that either the 'Home/Work' or 'Mobile' phone field has to be entered for the form to be valid. So both fields will be marked as a requirement to start with and the form becomes valid upon one of the fields being entered and valid, making the other field optional.

I hope that makes sense. Can someone please help with this one?

Please see below for my current HTML and JS.

<div class="user_bf_input">
<label for="cn_home">*Contact Number (Home/Work):</label>
<input name="cn_home" type="text" id="cn_home" size="15" />
</div>

<div class="user_bf_input">
<label for="cn_mobile">*Contact Number (Mobile):</label>
<input name="cn_mobile" type="text" id="cn_mobile" size="15" />
</div>

Open in new window


$(document).ready(function() {
&#9;$("#online_booking_form").validate({
&#9;&#9;rules: {
&#9;&#9;&#9;cn_home: {required: true, digits: true, minlength: 8},
&#9;&#9;&#9;cn_mobile: {required: true, digits: true, minlength: 10},
&#9;&#9;}
&#9;});
});

Change your script to group like:

<script>
$(document).ready(function() {
	  $('#online_booking_form').validate({ // initialize the plugin
        groups: {
            names: "cn_home cn_mobile"
        },
        rules: {
            cn_home: {
                require_from_group: [1, ".validateit"]
            },
            cn_mobile: {
                require_from_group: [1, ".validateit"]
            }
        },
        submitHandler: function (form) { // for demo
            alert('valid form submitted'); // for demo
            return false; // for demo
        }
    });

    jQuery.extend(jQuery.validator.messages, {
        require_from_group: jQuery.format("'Please enter either Home/Work or Mobile No fields.")
    });
});
</script>

Open in new window


Add Class to your input fields validateit like:

<div class="user_bf_input">
<label for="cn_home">*Contact Number (Home/Work):</label>
<input name="cn_home" type="text" id="cn_home" class="validateit" size="15" />
</div>

<div class="user_bf_input">
<label for="cn_mobile">*Contact Number (Mobile):</label>
<input name="cn_mobile" type="text" id="cn_mobile" size="15" class="validateit" />

Hi, I tried applying this to my code and it doesn't seem to be validating anything at all now, the form just submits. I have other rules for the form, will this make any difference in how it runs?

I would also like for the home and mobile phone fields to have min length and to be only digits too.

Please see below.

$(document).ready(function() {
$("#online_booking_form").validate({
		rules: {
			fname: {required: true, minlength: 3},
			lname: {required: true, minlength: 3},
			postcode: {required: true, minlength: 4},
			cn_home: {required: true, digits: true, minlength: 8},
			cn_mobile: {required: true, digits: true, minlength: 10},
			dob: "required",
			payment_method: "required",
			cc_type: "required",
			cc_number: {required: true, digits: true, minlength: 16, maxlength: 16},
			cvc_number: "required",
			other_source: "required",
			terms_of_booking: "required"
		}
	});
});

Click book now then try just submitting the form, the validation doesn't work anymore on the fields. The form just submits where as before the user was prompt to enter fields in.

I have the javascript in a seperate js file called booking-form.js if you look through a web inspector.

Ok, got it working, needed to include the file additional-methods.min.js

Only thing now, is that the other rules have stopped working.
cn_home and cn_mobile work but fname and lname don't!

Any chance you could update the jsfiddle with an example with other fields for name etc that need a required state with min character amount!

Many thanks!
