Problems with the editor example in ch 10

arne · August 21st, 2004, 07:42 AM

Hello !

Most of the scipts in the book works ok, but I can not get the editor.php script in ch 10 to work.

The editor menu comes up. Its possible to edit on the screen, but the save function does not work. The only thing that is happening is that the text fields are blanked out. No text are stored. There are no error messages.

I have checked the security and privat tabs on IE. They are on normal.

To be sure it has nothing to do with user rights on the server, I made chmod 777 on all files.

Server Fedora core 2, in my home.

I have some other PHP applications that uploads files to the web server. No problems with them.

I have checked the php.ini file. Cant see any problems.

Still the editor.php scripts in ch 10 is not able to store or upload any text to the web server.

Any ideas or suggestions ?

Best reg Arne.

This line has an empty action field. Is this right ??

<FORM NAME="edit_form" METHOD="POST" action="">

When trying to run it, the webeditor.php scripts also say: "You can't edit me".

From the script:

if($filename == basename($PHP_SELF)) error_message("You can't edit me!");

Some incorrect configuration ?

Problem solved via danish discussion group eksperten.dk

Problem apeared to be that the php.ini file of Fedora Core 2 has register_globals set to off. After changing this to on, the scripts vere working.

From the php.ini file:

; You should do your best to write your scripts so that they do not require
; register_globals to be on; Using form variables as globals can easily lead
; to possible security problems, if the code is not very well thought of.
register_globals = On

Well .. the book is prited in year 2000 and 4 year is a boit of time.
