hello every body, i am continuously having problem with chaptar 11
register.php. i am using iis in xp. i can connect with my mysql
database named "sample_db". user name "phpuser" and password "phppass"
though i have copied all files from chapter11 source folder to wwwroot.
 i can open the file register.php without having any problem. but when i give some input and press submit, nothing have happened. no error message or confirmation of creating the user. i also submit the page without filling any input field. thus a error page should be displayed. but nothing happens. what can i do now? could any body please help me?
please. i am looking forward to someone's help. please help me.

My solution at your problem is to add, before the last "switch" code, this:

else $_POST['action'] = "register";

Infact this specify another condition of "action".

With this code I have resolved this problem, that It was been my problem too.

Bye

stefanocinfo has overcome the problem by changing the way the switch works. He's saying if there is $_POST['action'] then it must be "register". That's OK in this case but in a more general case there could be more than one value for $_POST['action'] so more than one case within the switch.

The real cause of the problem is on page 436 - two lines from the bottom:
<input type="hidden" name="action">
this sets $_POST['action'] but leaves the value NULL
it should be
<input type="hidden" name="action" value="register">

Me too... I have a problem here in Chapter 11 in Beginning PHP5. Every I execute the sample code of the chapter it will appear an error message, states that there was an error in this code.:

<?php
for($i=0; $i < count($position_array); $i++){
   if(!isset($userposition) && $i == 0){
     echo "<OPTION SELECTED VALUE=\"". $position_array[$i] . "\">" . $position_array[$i] . "</OPTION>\n";
   }else if($position == $cposition_array[$i]){
     echo "<OPTION SELECTED VALUE=\"". $position_array[$i] . "\">" . $position_array[$i] . "</OPTION>\n";
   }else{
     echo "<OPTION VALUE=\"". $position_array[$i] . "\">" . $position_array[$i] . "</OPTION>\n";
   }
}
?>
