Should I worry about standards compliant code on dynamically

I am looking to create an address book type of application in (x)HTML/PHP/CSS/JavaScript (jQuery)/MySQL. I want to be able to allow for multiple inputs without originally coding for more than one. For instance, when a user navigates to the page, they may see the form initially with one phone number input. Since some people have home phones and mobile phones, I would like to be able to allow the user to create as many inputs as possible. The creation is not the problem, the validation is. I am a hardcore believer of standards compliant code. I will render the initial page as validated. The problem occurs when the user dynamically creates a new input field. Should I (a) not worry about validation as the code is client-side? (b) Number the initial id, use parseInt and increment any dynamically generated fields, essentially rendered standards compliant code? I am building the inputs with an array in the name attribute, i.e. name="phone_number[]".

Essentially, I am more or less looking for a professional opinion in this matter. My options are (a) don't worry about it, or (b) worry about it.

Also you may use the following code in the validation function:

if(isset($_POST['phone_number[$i]']){
// your validation here
}

I use ChronoEngine (ChronoForms) in Joomla. It uses LiveValidation for the fields.
Haven't used the php validation. LiveValidation is cool as it can validate as you type (prior to/prevent submit) and also with a delay, wait x-amount of time after you stop typing in the field - to validate/display msg.

This was a custom code for a phone-number field.

Code:

window.addEvent('load', function() {

  var phone_val = new LiveValidation('text_12', { wait: 1000 });
  phone_val.add(
    Validate.Format, {
      pattern: /^(?:(?:\+?1\s*(?:[.-]\s*)?)?(?:(\s*([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9])\s*)|([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9]))\s*(?:[.-]\s*)?)?([2-9]1[02-9]|[2-9][02-9]1|[2-9][02-9]{2})\s*(?:[.-]\s*)?([0-9]{4})$/i,
      failureMessage: 'Not a valid phone number.' });

  var fax_val = new LiveValidation('text_13', { wait: 1000 });
  fax_val.add(
    Validate.Format, {
      pattern: /^(?:(?:\+?1\s*(?:[.-]\s*)?)?(?:(\s*([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9])\s*)|([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9]))\s*(?:[.-]\s*)?)?([2-9]1[02-9]|[2-9][02-9]1|[2-9][02-9]{2})\s*(?:[.-]\s*)?([0-9]{4})$/i,
      failureMessage: 'Not a valid phone number.' });
});
