Detailed explanation of PHP form submission and processing of form data
This article introduces you to some knowledge points about forms, and then introduces how PHP receives form data and how to process form data. The article uses a form example for sending emails to explain form submission and how PHP processes form data. Need Friends can refer to
and first take a look at the source code of the html form:
<html> <head> <title>Feedback Form</title> </head> <body> <form action="feedback.php" method="post"> Name:<input type="text" name="username" size="30"> <br><br> Email:<input type="text" name="useraddr" size="30"> <br><br> <textarea name="comments" cols="30" rows="5"> </textarea><br> <input type="submit" value="Send Form"> </form> </body> </html>
The form starts with
End.action indicates which file the form should be submitted to for processing data. Here it is submitted to the feedback.php file for processing form data.
method indicates how to submit the form. There are generally two ways to submit the form, post method and get method. If you submit a form in the get method, the data will be displayed on the URL link. If you submit the form in the post method, the data will be hidden and will not be displayed on the URL link.
In this example, there are many html input tags, which are all form elements.
The code for php to process form data is as follows:
<?php $username = $_POST['username']; $useraddr = $_POST['useraddr']; $comments = $_POST['comments']; $to = "php@h.com"; $re = "Website Feedback"; $msg = $comments; $headers = "MIME-Version: 1.0\r\n"; $headers .= "Content-type: text/html; charset=iso-8859-1\r\n"; $headers .= "From: $useraddr \r\n"; $headers .= "Cc: another@hotmail.com \r\n"; mail( $to, $re, $msg, $headers ); ?>
Because the form is submitted in post mode, $_POST is used to obtain the form. data.
