PHP Working with Forms
Creating and Handling HTML Forms
Introduction
Forms play an important role in web development as they allow users to
interact with websites by submitting data such as names, emails, passwords,
and feedback. In PHP, forms are commonly used to collect user input and
process it on the server side.
Definition Of Forms
Forms are the basic interface between user and server. Form handling is the basic and important feature of PHP.
Creating Forms In PHP Using HTML
1. HTML Form Setup
❖ Being by setting up on html form using element.
❖ Specify the action attribute to indicate the URL that will process the form
submission.
Example :
2.Form Elements :
❖ Inside the tag add various form elements such as text fields ,checkboxes
,radio buttons and text areas.
3.PHP Script :
● In the form php file process the form data submitted by the user. We can access the
form values using $ _post[‘fieldname’].
🧩Example -
tag
➢ The array name is declared to handle multiple selection options and each
tag represents a distinct group.
➢ The values selected are submitted as an array when the form is processed and the backend ,such as in php,can access and handle these selected groups.
Form Data Submitted:"; echo "Name: ". $name. "
"; echo "Gender: ". $gender. "
";
if(!empty($_POST['skills'])) { echo "Skills: "; foreach($_POST['skills'] as $skill) { echo $skill. " "; } echo "
"; }
echo "Comments: ". $comments; } ?>
