  1. On page 92, Chapter 3, making sticky forms: In this chapter a form is created with PHP used to create a text field for inputting distance. Code then validates the content to make sure it is present and a number. The form remembers what was entered so that if an error is thrown the previous input is still there. The following code is used to remember the distance entered by the user. <?php if (isset($_POST['distance'])) { echo $_POST['distance']; } ?> The book then remarks that this can be condensed onto one line, i.e. <?php if (isset($_POST['distance'])) echo $_POST['
  2. Greetings to all (and especially you Larry) I'm having difficulties getting the CSS to show and I think there is something wrong with my path to CSS. I like to have things tidy and pretty so I created a subfolder in my www root called "myCMS". FileStructure = myCMS(folder) index.php assets(folder) css(folder) style.css img(folder) logo.png includes(folder) header.html footer.html I get the includes to work and they show when rendering index.html but there is no styling... In header.html I have <link href="assets/css/style.css" rel="stylesheet"> Bu
  3. Hi guys, I've been going over chapter 3 today, script 3.10 calculator.php #5 and unless I'm being stupid (most likely) is their an error on line 30 ?

  4. I get the following error when I run the sessions.php script which includes the session handler functions line 37 is the call to session_write_close(); What does this mean exactly and how do I rectify it? Incidentally there is a session text file being saved in the tmp directory referred to - its full of data that I don't understand.
  5. Hi, Obviously I'm new here, and fairly new to PHP - so far this book has been very helpful and usually easy to follow. I got the 3rd edition from the library and got through Chapter 10 before ordering the 4th edition when it came out. So now I'm just skimming back through the early chapters to see what's different. The calculator script is quite different, and I was wondering about the method of checking if the form has been submitted. The earlier version used a hidden form input and checked if the value was set, the new one checks if $_SERVER['REQUEST_METHOD'] is POST. What's the differ
