scriptham Posted December 26, 2007 Share Posted December 26, 2007 Hi I am struggling to get the following script to work. As you can probably guess it is from a book. I am working towards a modest website and this is my starting point. The basic idea is that the user guesses the num_to_guess entering their guess in the html form and submitting it. The php then checks it against the preset value and displays a higher, direct hit or lower type message. When run the form appears but in use the message does not change, can anyone spot the error please. I am using the Abyss webserver in winXP it is set up to run php and some basic php has already worked so I believe the set up is correct. <?php $num_to_guess = 42; if (!isset($_Post[guess])) { $message= "Welcome to the guessing machine"; } else if ($_Post[guess] > $_num_to_guess) { $message= "$_Post[guess] is too large. Try a smaller number."; } else if ($_Post[guess] < $_num_to_guess) { $message= "$_Post[guess] is too small. Try a larger number."; } else { $message= "Well Done"; } //unset ($_Post[guess]); ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title>Page title</title> </head> <body> <form action="<?php echo $_SERVER[php_SELF] ?>" method="POST"> <p>Type your guess here: <input type="text" name="guess"/></p> <p><input type="submit" value="submit your guess"/></p> </form> <?php <h1> echo $message </h1> ?> </body> </html> I look forward to hearing from you.
