Textarea is a crucial HTML element that plays a significant role in the development of web applications. It is used to receive inputs from the user and then sending that input to the server to process. PHP is one of the most widely used server-side programming languages that enables developers to write server-side scripts for web applications. In this article, we will discuss how to get value of textarea in PHP with code examples.
Getting Value of Textarea in PHP
In PHP, you can easily obtain the value of textarea using the $_POST or $_GET global variables. These variables are used to retrieve values that are submitted through a form, which is then sent to the server for processing. In this tutorial, we will use the $_POST variable to retrieve the value of textarea.
Code Example 1: HTML Form with Textarea
To retrieve the value of the textarea, we need to create an HTML form with a textarea element in it. Here is an example of how to create a form with the textarea element:
<title>Get Textarea Value in PHP</title>
<form method="POST" action="">
<input type="submit" name="submit_button" value="Submit">
In this code, we have created an HTML form that contains a textarea element with the name attribute "input_text". The form has a submit button that will submit the form data to the server.
Code Example 2: PHP Script to Retrieve Value of Textarea
Now, we will write a PHP script to retrieve the value of the textarea. The script will check whether the form has been submitted or not. If the form has been submitted, it will retrieve the value of the textarea using $_POST global variable. Here is the code:
$input_text = $_POST['input_text'];
In this code, we are using the isset() function to check whether the form has been submitted or not. If the form has been submitted, it will retrieve the value of the textarea using the $_POST['input_text'] global variable and store it in a variable called $input_text. Finally, we are echoing out the value of $input_text.
In this article, we have discussed how to get value of textarea in PHP with code examples. We have seen that it is quite easy to retrieve the value of the textarea using the $_POST global variable. We have provided you with a code example of an HTML form and a PHP script that shows how to retrieve the value of the textarea. We hope that this tutorial was helpful to you.
