Still lost in a session!??

Anon

Can someone please send me a "working" code example of how to pass a user selected variable (form a drop down box) to several pages and then upon return to original page allow user to re-select a new selected variable (say for a TableName?). I have tried for a week or more and am still no closer to completing this task? I appreciate any help. If you want I am willing to take a "walk" through with you as I really really need/want to know this well. Thanks again.

Marcel.

Just want to know if I understand it all correctly...is this the correct logic?

Start session--->register session---->assign session var---->pass session var.

Did you read the manual section about sessions and the most common mistakes people make?

The correct sequence is

start session
put variables in
print url to next script, including SID
exit

Then on the next page:

start session (the session ID is taken from the url)
use variables
exit

Something like this should work:

script1.php:
session_start()
$HTTP_SESSION_VARS["myvar"]="hello";
print "<a href=script2.php?".SID.">click me</a>";
exit;

script2.php:
session_start();
print $HTTP_SESSION_VARS["myvar"];
exit;

I have read and re-read the manual pertaiing to sessions however, I didn't see nor have I found a section on common mistakes. Do you have a link I can follow? I am in the process of applying your code example to my script, I'll let you know of my success...if any 🙂. Thanks for the help.

Tried the code snippet you provided but with no luck. As a side note though, I also tried to create a user authentication script but keep getting an empty string in $PHP_AUTH_USER? Is there an option during install to allow for this? My isp probably has this turned off....so I'll have to do it the longer way. 🙂

Did you make sure your php and browser all use cookies?

Show us the code you use to test the cookies, maybe we can find a problem.

Yeah...both use them. But I did discover that I can't use the $PHP_AUTH_USER etc. for authenticating a user. I think it's 'cause my host installed php using the cgi method rather than the apache module. Still looking into it.

That wouldn't affect sessions though would it? Doesn't seem logical to. Anyway I'll get that code together, clean it up and post it....I tried so many things I trashed it. I sort of cheated and removed the option I needed the sessions for...🙂 temporarily, just to get it up and running.

OK, it's running, now I will go back and figure out how to add the functionality, of allowing a user to select a database table from a drop down and then passing this selection to my add script, modify script, delete script and update script as needed. I think I'll try a simple test first to make sure it even works! Before I trash my code again!

Thanks again for your help, I really appreciate it.
