First copy this code then make a file name grade_submit.php. POST method are applied for this form.

<?php if(($_SERVER['REQUEST_METHOD'] === 'POST') ){ $mark = $_POST['mark']; if( !empty($_POST['mark'])){ if(preg_match("/[A-Z a-z]$/", $_POST['mark'])){ //to make form validation for alpha as it supports only the numeric echo "alpha value is not valid"; } else if($mark>100 || $mark<0) echo "Invalid"; else if($mark>=80) echo "A+"; else if($mark>=75) echo "A"; else if($mark>=70) echo "A-"; else if($mark>=65) echo "B+"; else if($mark>=60) echo "B"; else if($mark>=55) echo "B-"; else if($mark>=50) echo "C+"; else if($mark>=45) echo "C"; else if($mark>=40) echo "D"; else if($mark <40) echo "Failed"; } else echo "mark field is blank"; } ?>

Then make a form with simple html mark up like this and save this as a php file. action name must be as the php file name. Or you can put the both file as a same file.

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Mark Submission Form</title> </head> <body> <form action="grade_submit.php" method="post"> <input type="text" name="mark" /> <input type="submit" value="Submit"> </form> </body> </html>
