guayaquil Posted August 18, 2006 Share Posted August 18, 2006 I recently bought [i]PHP 5/MySQL Programming for the absolute beginner,[/i] because I am. I have installed PHP 5.1.4 on my Mac OS X running Apache 1.3 and it works. When I call the info, the info page shows up. However, when I try any of the scripts from the book, they don't work. So is there a version conflct? or something about the author's syntax that's wrong? Here is the code as I use it:<html><head><title>Hi User</title></head><body><h1>Hi User</h1><?if (empty($username)) { print <<<HERE <form> Please enter your name: <input type = "text" name = "username"><br> <input type = "submit"> </form>HERE;} else { print "<h3>Hi there, $username!</h3>";} //end?></body></html>If it is really apparent to you, then I apologize. But I am only beginning and it's frustrating if I can't even use the code in a book for beginners. help. This is what I get:[img]http://www.el-cordovez.com/result.gif[/img] Link to comment https://forums.phpfreaks.com/topic/17927-scripts-from-my-book-dont-work-why/ Share on other sites More sharing options...
Cook Posted August 18, 2006 Share Posted August 18, 2006 That's because the script in your book relies on REGISTER_GLOBALS being turned on, when very likely your csetup has it off (default setting of PHP nowadays).Use $_REQUEST['username'] instead of just $username and it should work better.I used $_REQUEST because I don't remember if the default method for a form is GET or POST, so $_REQUEST will work either way. But better would be to specify the method in the <form> tag:print <<<HERE<form name="myform" method="post" action="$_SERVER['PHP_SELF']">(...)Then you can use $_POST['username'].

guayaquil Posted August 18, 2006 Author Share Posted August 18, 2006 Thanks cook, but since I am going to be using so many scripts from this book, shouldn't I just turn on Register_Globals?

Register_globals is set as default OFF for very good reasons.

Sounds like an old book with a new cover and a few php5 functions thrown in.

guayaquil Posted August 18, 2006 Author Share Posted August 18, 2006 NOOOOO! don't tell me I wasted €31 on an outdated book. So it's the difinitely the REGISTER_GLOBALS? the issue? Bummer. This is not very encouraging. Who knows what else would be outdated in the book. Is there a reference for updated tags/comands, etc. for PHP 5?

.josh Posted August 27, 2006 Share Posted August 27, 2006 ... and this is why I went for Php in easy steps, instead of some really thick book. it cost me 10 bucks, showed me the basics, and from there, it was the online manual.
