</label>

</div>

Answer 1

This should work
<form name="register_form" ng-submit="submitDetails(user)" novalidate="">
<div class="list">
<label class="item item-input item-floating-label" style="position:relative;">
<span class="input-label">First Name</span>
<input type="text" name="user_first_name" placeholder="First Name" ng-model="user.firstName" ng-required="true">
<p ng-show="register_form.user_first_name.$invalid && !register_form.user_first_name.$pristine" class="help-block">You name is required.</p>
</label>
<!--omitted-->
<input type="submit" class="button button-royal" value="register">
</div>
</form>
Form name is register_form,
<form name="register_form" ng-submit="submitDetails(user)" novalidate="">
Input name is user_first_name,
<input type="text" name="user_first_name" placeholder="First Name" ng-model="user.firstName" ng-required="true">
So validation must pass through those fields
<p ng-show="register_form.user_first_name.$invalid && !register_form.user_first_name.$pristine" class="help-block">You name is required.</p>
Model itself doesn't have $invalid or $pristine properties, so it doesn't make sense
For phone field
<input type="number" name="user_phone" placeholder="Phone No" ng-model="user.phone" ng-minlength="10" ng-maxlength="10" ng-required="true">
<span class="help-block" ng-show="register_form.user_phone.$error.required || register_form.user_phone.$error.number">Valid phone number is required</span>
<span class="help-block" ng-show="((register_form.user_phone.$error.minlength || register_form.user_phone.$error.maxlength) && register_form.user_phone.$dirty) ">phone number should be 10 digits</span>

Try this:
1) Give name attribute to your form
<form name="myForm" novalidate>
2) declare the request types inside of your scope like this:
$scope.requestType = [
{ code: "carPass", name: "Car Pass Ticket" },
{ code: "seminarPass", name: "Seminar Pass" },
{ code: "identityCard", name: "Identy Card"}
];
3) declare select box like this:
<select name="requestType" ng-model="request" required
ng-options="request.code as request.name for request in requestType" >
<option value="">--Please select--</option>
</select>
4) Inside submit method check for $valid attribute of form.
$scope.submit1 = function(description){
if($scope.myForm.$valid){
// Do your stuff
}else{
// Do your stuff
}
}
