Here is the code in one html file I run first

<HTML>
<HEAD></HEAD>
<BODY>
<FORM method="get" action="text.php">
WHo is your favourite authors?
<input type=submit>
<br>
<input name="choice1" type="checkbox" value="111" checked >
<input name="choice2" type="checkbox" value="222" checked >
<input name="choice3" type="checkbox" value="333" checked >

</FORM>
</BODY>
</HTML>

then here is the code of text.php
<HTML>
<HEAD></HEAD>
<BODY>
Your favorite author is:
<?php
echo $aaa;
echo $choice1;
echo $choice2;
echo $choice3;
?>
</BODY>
</HTML>

when I just check some of the checkboxes and then press submit.
The wrong message show up as following:

Notice: Undefined variable: choice3 in c:\inetpub\wwwroot\text.php on line 9

but in the book, it only mentioned that the the checkbox not ticked will not be transfer to PHP engint and will not show its value. so is there any configuration in PHP to delete this Notice information?

Thanks!

Thanks!

You need to set the Error handling in your php ini file to how you want errors displayed.

The book was written before the PHP group had decided to change the default value of error_reporting in php.ini. The best way to adapt your code is the write this equivelent: (You should also be using the $_GET[""] super global array)

<?php
if (isset($_GET["aaa"])) {echo $_GET["aaa"];}
if (isset($_GET["choice1"])) {echo $_GET["choice1"];}
if (isset($_GET["choice2"])) {echo $_GET["choice2"];}
if (isset($_GET["choice3"])) {echo $_GET["choice3"];}
?>

This code works with both of the new defaults set in php.ini, error reporting E_ALL and register_globals = off.

There are a multitude of reasons for adapting your code to work with these new standards!

See Nik's register globals FAQ:

And see this topic on error reporting:

When I run the sample code by richard.york, I get no errors. Actually, the i.e. screen goes blank.Ã Ã What could be causing this. I have errors set to E_ALL and register_globals = off I am using PHP5
