HTML tags formatting is an essential element of web development. It allows developers to structure and organize content on a webpage, making it more user-friendly and visually appealing. One of the most useful applications of HTML tags formatting is obtaining the URL hash from the server side. In this article, we will explore what URL hash is and how to obtain it from the server side using HTML tags formatting.
First, let's understand what a URL hash is. A URL hash, also known as a fragment identifier, is a string of characters that appears at the end of a URL. It is preceded by a # symbol and is used to identify a specific portion of a webpage. For example, in the URL https://www.example.com/about#history, the hash is "history," which indicates that the webpage is about the history of the company.
Now, let's dive into the process of obtaining the URL hash from the server side. Before we begin, it is essential to note that this process involves using server-side scripting languages like PHP or ASP, so some knowledge of these languages is necessary.
Step 1: Create the HTML form
The first step is to create an HTML form on the webpage where the URL hash needs to be obtained. The form will contain a field for the user to enter the URL and a submit button. The code for the form will look like this:
<form action="get_hash.php" method="post">
<label for="url">Enter URL:</label>
<input type="text" name="url" id="url">
<input type="submit" value="Get URL Hash">
</form>
Step 2: Create the server-side script
Next, we need to create a server-side script that will process the form data and extract the URL hash. For this example, we will use PHP. The code for the server-side script will look like this:
<?php
// Get the URL from the form
$url = $_POST['url'];
// Use the parse_url function to extract the hash
$hash = parse_url($url, PHP_URL_FRAGMENT);
// Echo the hash
echo "The URL hash is: " . $hash;
?>
Step 3: Test the code
Save the HTML form and the server-side script in the same directory and open the HTML form in a web browser. Enter a URL with a hash in the form field and click on the submit button. The server-side script will extract the hash and display it on the webpage.
Congratulations, you have successfully obtained the URL hash from the server side using HTML tags formatting!
In conclusion, HTML tags formatting is a powerful tool that allows developers to manipulate and extract data from webpages. In this article, we have learned about URL hash and how to obtain it from the server side using HTML tags formatting. This technique can be helpful in various scenarios, such as creating dynamic content or tracking user interactions on a webpage. With some basic knowledge of server-side scripting, you can easily implement this feature on your website and enhance the user experience.
