login page: MX/PHP? Any thoughts ?

**rikmg** · May 21, 2003, 13:58

Using Dreamweaver MX, Iam attempting to create a login page/register page in PHP, its adding users to the mysql database, but when i add a username that already exists its supposed to divert to another page called taken.php, & also an error page when the login fails,however its still taking me to the welcome page ! whatever i do ? any thoughts ?

the login page comes back with various errors too, am i missing some important values ? the code for the login is below...

this is my first attempt, be kind !

this is the error i get back from the login.php page,

Warning: open(/tmp\sess_61267ce9f0e04fa7dcd729aaad604a4c, O_RDWR) failed: m (2) in C:\apache\htdocs\login.php on line 4

and:

Warning: open(/tmp\sess_61267ce9f0e04fa7dcd729aaad604a4c, O_RDWR) failed: m (2) in Unknown on line 0

Warning: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0

Cheers !!

Richard.

Create a "temp" dir off of your root. ie: C:\temp

**rikmg** · May 21, 2003, 14:03

running on localhost with phpmyadmin apache,mysql all combined, what would the Session variable look like from session_start(); where would is my php.ini stored ?

**rikmg** · May 21, 2003, 14:04

so would i create the temp folder in the apache folder or in htdocs ?

**PHP John** · May 21, 2003, 14:05

Do a search for "php.ini". In it you will find a line like this:

; Argument passed to save_handler. In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP's session functions.
session.save_path = /tmp

This would be the server root.

**rikmg** · May 21, 2003, 14:05

i tried to add another user to the db, via kevins method and now i get submission error again without changing anything previously...

**rikmg** · May 21, 2003, 14:06

i created a directory in the apache folder, i'll slow down in my excitement that you may e able to help..

**rikmg** · May 21, 2003, 14:12

i've found the file, now i have the temp folder in the apache folder is this my server root, sorry if i sound dumb...

**rikmg** · May 21, 2003, 14:19

i changed it to this;

; Argument passed to save_handler. In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP's session functions.
session.save_path = C:/apache/temp

still no joy....

**Hartmann** · May 21, 2003, 14:28

Have you tried

session.save_path = C:\apache\temp

??

**rikmg** · May 21, 2003, 14:29

is it really that fussy ?

It may or may not be... I am not 100% sure.

Also, make sure that after you make changes to the ini file, you restart Apache.

**rikmg** · May 21, 2003, 14:31

still getting databse error occured in your script iam using the tutorial from kevins PHP sessions/mysql user login tut.

**rikmg** · May 21, 2003, 14:33

it worked once and added a user to the db then stopped and i changed nothing, did something time out ?

**rikmg** · May 21, 2003, 14:43

I would have thought this would have been relatively easy to sort out, why is it so fussy ? why add one then fail ? looks like Access/ASP or coldfusion is calling !! More expensive yep, but more reliable ? i refuse to give up on this though !!

I don't think it is a question of reliability, maybe just customization.

Try downloading phpdev from http://www.firepages.com.au

You can program your site in MX and just run them from the web browser. Everything works out of box with the phpdev setup. Just read the directions and run the install file.
