You're missing ng-model on every field of your form. Keep in mind when you mention ng-model on any form field at that time ng-model creates the extra objects inside form name object with that specific name attribute which then considered while form validation like $error, $valid, $invalid, etc.

As your form name is blgoPost, when angular compile this page,it internally creates the object inside the scope of the name of blgoPost. And the all the input fields which has name & ng-model assign to them gets added inside that blgoPost object. But if you don't mention ng-model to the form fields then it will never get added inside the blgoPost form object.

HTML

<form role='form' name='blgoPost' novalidate="">
    <input name="first" />
    <div class='form-group'>
        <label for='blgoTitle'>Title</label>
        <input name='title' type="title" class='form-control' ng-model="test1" placeholder='Technologies of the Future' required="">
        <br>
        <label for='blgoContent'>Content</label>
        <textarea name='content' rows='8' type="content" ng-model="test2" class='form-control' placeholder='The technical innovations of the future will be diverse and impactful on the individual......' required=""></textarea>
        <br>
        <label for='blgoPassCode'>PassCode</label>
        <input name='passcode' type="passcode" ng-model="test3" class='form-control' placeholder='&#8226;&#8226;&#8226' required="" />
        <br/>
        <button type="submit" class='btn btn-primary' ng-disabled="blgoPost.$invalid">Submit Post</button>
    </div>
</form>

I am trying to use the angular form validations in my form for a blog post, and more specifically a ng-disabled form. For reasons I cannot figure out the submit button is not disabled, where as it should be unless all three input fields are valid. Thanks for the help.

this is my blog template

 <div ng-controller='BlgoCtrl'>
  <div class='container'>
    <h1> Teewinot Blgo</h1>
    <div class="row">
      <div class='col-md-12'>
        <form role='form' name='blgoPost' novalidate>
          <div class='form-group'>
          <label for='blgoTitle'>Title</label>
          <input name='title' type="title" class='form-control'  placeholder='Technologies of the Future' required><br>
          <label for='blgoContent'>Content</label>
          <textarea name='content' rows='8' type="content" class='form-control' placeholder='The technical innovations of the future will be diverse and impactful on the individual......' required></textarea><br>
          <label for='blgoPassCode'>PassCode</label>
          <input name='passcode' type="passcode" class='form-control' placeholder='&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;&#8226;' required><br>
          <button type="submit" class='btn btn-primary' ng-disabled="blgoPost.$invalid">Submit Post</button>
          </div>
        </form>
      </div>
    </div>

Here is my index.html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Teewinot</title>

  <script src="bower_components/angular/angular.js"></script>

  <script src="bower_components/jquery/dist/jquery.js"></script>
  <script src="bower_components/bootstrap/dist/js/bootstrap.js"></script>
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <script src="bower_components/angular-route/angular-route.js"></script>
  <link href="bower_components/bootstrap/dist/css/bootstrap.css" rel="stylesheet">

</head>

<body ng-app="Teewinot">
<ng-include src="'app/templates/partials/navbar.html'"></ng-include>

<ng-view></ng-view> 
<!-- angular module defintion and reoutes -->
<script src="app/js/app.js"></script>
<script src="app/js/routes.js"></script>
<!-- controllers -->
<script src="app/js/controllers/blog.controller.js"></script>

</body>
</html>

This is my blog controller

angular.module('Teewinot').controller('BlgoCtrl', function($scope, $http) {
  'use strict'
});

And where is your code that sets the $invalid value ?

Instantiate the module as angular.module('Teewinot', []). Pass an empty array to the module function. And, also use ng-model for each input.
