In this tutorial, we will be creating a simple HTML5 application that will allow us to send data from a form to a back end server. This back end will be run on a separate server, and our goal is to make it as easy as possible for us to connect to it and work with the data that’s been collected.
We will be using the Form post feature of HTML5 to send data from our form to our back end, and we will also be using the JSON object feature of HTML5 to make sure that our data is properly formatted. We will also be using the localStorage feature of HTML5 to store any data that we collect from our form.

Introduction
In this blog article, we will create a simple HTML application that will use a Form post to access the back end. The application will have two main pages: one that displays a list of cities, and the other that allows users to input new city information.
To get started, create a new HTML document in your favorite editor and type the following code into it:
<!DOCTYPE html> <html lang=”en”> <head> <title>HTML Application with Form Post to Back End</title> </head> <body> <h1>HTML Application with Form Post to Back End</h1> <!– Include the necessary files –> <script src=”https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js”></script> <script src=”https://ajax.googleapis.com/ajax/libs/formidable/0.8rc3/formidable-min.js”></script> <!– Include our form template –> <form action=”/mycitylist/” method=”post”> City Name:<input type=”text” name=”cityName”/> </form> <!– Display the list of cities –> <ul id=”citiesList”> </ul> <!– Get the value of the “cityName” field from our form submission –> var cityName = $(‘.
Requirements
In this HTML application with Form post to back end tutorial, you will learn how to create a simple online form using HTML and CSS. Once the form is created, you will use a PHP script to send the data collected from the form to a back end system. The final result of this tutorial will be a working online form that you can use for your own projects.
Required skills:
-Basic knowledge of HTML and CSS
-Knowledge of PHP scripting
-A basic understanding of databases (e.g., MySQL)
Application Overview
A HTML application with a Form post to the back end is an easy way to create a basic online form. The code required is minimal and can be found in most web development frameworks.
There are three main sections to this article: setting up the HTML, creating the Form, and submitting the Form data.
First we need some simple HTML to display our form:
<form action=”/submit” method=”post”> <input type=”text” name=”email” placeholder=”Email address” /> <input type=”text” name=”name” placeholder=”First name” /> <input type=”submit”> </form>
Next we need a form element that will house our input elements:
<div> <form action=”/submit” method=”post”> <input type=”text” name=”email” placeholder= “Email address”></form> <input type=”text” name= “name” placeholder= “First name”></form> </div>
Finally, we’ll need some CSS to style our form:
div { position: relative; padding-left: 20px; padding-right: 20px; } form { margin-bottom: 10px; width: 900px; } input[type=”text”], input[type=”password”], textarea { width: 100%; }
Now let’s take a look at the code that creates and submits our Form.
var form = document.getElementById(“form”); // create the form element form.addEventListener(“submit”, function(e) { e.preventDefault(); // process the ‘submit’ event }); // add an event listener to handle submit events
form.onsubmit = function() { // submit the form };
In this code, we first get hold of our form element using the document.getElementById() method. We then add an event listener for the submit event, which will be triggered when the user clicks on the form’s submit button. Finally, we handle the submission event by calling e.preventDefault() , which will prevent the browser from submitting the form on behalf of the user.
HTML5 Basics
HTML5 is the latest revision of the HTML language and defines a new way to create web pages. With HTML5, you can create more dynamic and interactive websites by using tags to define the structure of your document, including input fields, buttons, and forms.
To create a form with HTML5, you first need to include the form tag in your document. The form tag provides all the basic information about your form, such as its name and id attribute. You then need to add individual tags for each field in your form. For example, if you want to add a text field for user input, you would use the <input> tag. To specify the type of input field (e.g., text or number), use the type attribute.
Once you have added all of your fields, you need to specify a button that will trigger submission of the form data. To do this, use the submit() tag and provide a value for its action attribute. Similarly, you can add other tags to define other elements in your form (e.g., label tags for labeling fields). When your page is loaded into a browser, users will be able to enter data into these fields and submit them via buttons or Form submissions buttons on your website’s front end.
Form post Basics
HTML application with Form post to back end
Form posts can be used as a simple, yet powerful way to communicate with a back end. By using form posts, you can easily create applications that require authentication or submission of data. In this tutorial, we will create a simple HTML application that uses form posts to submit data to a backend server.
First, we will create our HTML skeleton and include the necessary form tags. Next, we will add our JavaScript code to initialize and handle the form submissions. Finally, we will attach our form data to the DOM element and display it onscreen.
HTML Application with Form post to back end
In this article, we will develop an HTML application using Form post to back end. The purpose of this application is to capture the age of a user and save it in a database. We will be using PHP as our back end language and MySQL as our database platform.
First, we need to create a FORM file that handles the POST activity. The FORM file should have the following structure:
Fieldset 1
<input type=”text” name=”age” id=”age”/>
Fieldset 2
<button type=”submit”>Submit</button>
We will also need to create a controller class that handles the POST action on our form. The controller class should have the following structure:
<?php //controller class definition /** * Handle POST form data */ function handlePost($data) { //validate data $valid = checkAge($data); //save data if ( !$valid ) { echo “Invalid Age!”; } else { //create record in database } } ?>
Now that we have created our form and controller, we can start coding our HTML application. In order to render our form, we will use the following code:
<!DOCTYPE html> <html lang=”en”> <head> <meta charset=”utf-8″> <title>HTML Application with Form Post</title> </head> < form action=”post.php” method=”POST”> <fieldset> <legend>AGE</legend> <input type=”text” name=”age” id=”age”/> </fieldset>
<div class=”submit”>Submit</div> </form>
We will also need to include the following code in our post.php file to handle the POST activity:
Now that we have coded our HTML application, we can start testing it by submitting the form. We can do this by running the following command in the terminal:
php post.php
If everything goes well, we should be able to see the age entered into our form reflected in the output window.
