Populate ng-model - Value not working AngularJS - php

Question

I have an AngularJS front end for a new internal web portal I am building. Using value={{data.Param}} I have successfully gotten my get and create requests to work via Slim PHP. Now however I am trying to create a PUT request and I am running into an issue.
This is the current code for my "Update /PUT" page.
request-edit.html
<div class="jumbotron text-center">
<form class="form-horizontal" role="form">
<div class="form-group">
<div class="text-center">
<h1>{{ header }}</h1>
<br/>
<h3>{{ request.Header }}</h3>
<br/>
</div>
</div>
<div class="form-group">
<label class="col-sm-3 control-label">Id:</label>
<div class="col-sm-3">
<input name="id" class="form-control" type="text" value="{{request.ID}}" disabled />
</div>
<label class="col-sm-3 control-label">Date:</label>
<div class="col-sm-3">
<input type="text" class="form-control" value="{{ request.Date_Submitted }}" disabled/>
</div>
</div>
<div class="form-group">
<label class="col-sm-3 control-label">Change Initiator:</label>
<div class="col-sm-3">
<input type="text" class="form-control" placeholder="{{request.Change_Initiator}}" ng-model="request.changeInitiator"/>
</div>
<label class="col-sm-3 control-label">Risk Level:</label>
<div class="col-sm-3">
<input type="text" class="form-control" placeholder="{{ request.Risk_Level }}" ng-model="request.riskLevel" />

<div class="col-sm-3">
<input type="text" class="form-control" placeholder="{{ request.Close_Date }}" ng-model="request.closeDate" />
</div>
</div>
<div class="form-group">
<label class="col-sm-3 control-label">Work to be Performed:</label>
<div class="col-sm-3">
<textarea name="request.description" ng-model="request.workToBePerformed" placeholder="{{ request.Work_to_be_performed }}" ></textarea>

<label class="col-sm-3 control-label">Backout Plan:</label>
<div class="col-sm-3">

My confusion in with ng-model, value and placeholders. Currently all my data populates in the form, but when the user goes to update the page they have to re-fill out every box or else blank data will be pushed. I understand the Placeholder does not actually fill in the data - however I have been un-able to use both ng-model and value on the same input field.
My top two fields populate using value just fine, but I do not want people to edit the date or ID. My other fields show the correct data in a temp form using placeholder but do not populate using ng-model. Additionally when my user goes to make the update the ng-model DOES function.
So in short my current issue is that ng-model does not display the original data- but does push it correctly. This causes my users to have to re-type all the data everytime or else the record will be updated with null values.
Below is the rest of my logic for review.
app.js
var app = angular.module('changeControlApp', [
'ngRoute',
'ngResource'
]);
//This configures the routes and associates each route with a view and a controller
app.config(function($routeProvider, $locationProvider) {
//$locationProvider.html5Mode(true);
$routeProvider
.when('/', {templateUrl: 'app/partials/request-list.html', controller: 'viewController' })
.when('/requests', {templateUrl: 'app/partials/request-list.html', controller: 'viewController' })
.when('/requests/create', {templateUrl: 'app/partials/request-create.html', controller: 'createRequestController' })
.when('/settings', {templateUrl: 'app/partials/settings.html', controller: 'settingsController'})
.when('/requests/:id', {templateUrl: 'app/partials/request-view.html', controller: 'viewRequestController' })
.when('/requests/edit/:id', {templateUrl: 'app/partials/request-edit.html', controller: 'editRequestController' })
.otherwise({ redirectTo: '/' });
});
app.controller('editRequestController', function($scope, $location, $route, $routeParams, $resource) {
$scope.header = 'Edit Change Request';
// Update User details
var request_Id = $routeParams.id;
if (request_Id) {
var Request = $resource(('http://pdgrosit02v/changeRequest/app/api/requests/'+ request_Id));
$scope.request = Request.get();
}
$scope.updateRequest = function() {
var RequestPut = $resource(('http://pdgrosit02v/changeRequest/app/api/requests/'+ request_Id), {}, { update: { method: 'PUT'}} );
RequestPut.update($scope.request, function() {
// success
$location.path('/requests');
}, function() {
// error
console.log(error);
});
}
});
And the Slim file
index.php
<?php
require 'Slim/Slim.php';
\Slim\Slim::registerAutoloader();
use Slim\Slim;
$app = new Slim();
//$paramValue = $app->request->params('paramName');
$app->get('/requests', 'getRequests');
$app->get('/requests/:id', 'getRequest');
$app->post('/requests/create', 'addRequest');
$app->put('/requests/:id', 'updateRequest');
$app->run();
function updateRequest($id) {
$request = Slim::getInstance()->request()->getBody();
$data = json_decode($request, true);
$sql = "UPDATE change_request SET Change_Initiator=:changeInitiator, Change_Initiator_id=:changeInitiatorId, Risk_Level=:riskLevel, Requestor=:requestor, Work_to_be_performed=:workToBePerformed, Backout_Plan=:backoutPlan, Backout_Time=:backoutTime, Implementation_Date=:implementationDate, Header=:title, Systems_Affected=:systemsAffected, Implemented_By=:implementationBy WHERE ID=$id";
//$sql = "UPDATE change_request SET Change_Initiator=:changeInitiator WHERE ID=$id";
try {
$db = getConnection();
$stmt = $db->prepare($sql);
$stmt->bindValue(":changeInitiator", $data['changeInitiator']);
$stmt->bindParam(":changeInitiatorId", $data['changeInitiatorId']);
$stmt->bindParam(":riskLevel", $data['riskLevel']);
$stmt->bindParam(":requestor", $data['requestor']);
$stmt->bindParam(":workToBePerformed", $data['workToBePerformed']);
$stmt->bindParam(":backoutPlan", $data['backoutPlan']);
$stmt->bindParam(":backoutTime", $data['backoutTime']);
$stmt->bindParam(":implementationDate", $data['implementationDate']);
$stmt->bindParam(":title", $data['title']);
$stmt->bindParam(":systemsAffected", $data['systemsAffected']);
$stmt->bindParam(":implementationBy", $data['implementationBy']);
$stmt->execute();
$db = null;
echo json_encode($data);
} catch(PDOException $e) {
echo '{"error":{"text":'. $e->getMessage() .'}}';
}
}

I figured out the issue, turns out Value and ng-model conflict and I had to modify my form to get the data correctly.
I removed all value commands and replaced them with ng-model="data.keyvalue". I was confused before as I thought you needed to use {{}} when referencing things off the scope.
I also added form validation for updating - new code below
request-edit.html
<div class="jumbotron text-center">
<form class="form-horizontal" role="form" name="requestEditForm" ng-submit="updateRequest()">
<div class="form-group">
<div class="text-center">

<br/>

<input name="title" id="title" class="form-control" type="text" ng-model="request.Header" />
<br/>

<div class="form-group">
