SESSION Traffic

deezzer

Hi.

This registration page uses the GD library and there are 3 files (as i number them off #):
#1 - register.php which calls the html template named -
#2- register.html and which calls the GD image file named -
#3- image.php

When i set session values in #1 and echo them in #2: works.
Problem: when i set session values in #1 and pass it through #2 - (works), but from #2 to call the GD image file #3, doesn't work.
When i set sessions in #3 and pass it over to #2, doesn't work.

I'm starting a session_start in both #1 and #3, still nothing.

I have reason to believe it's not the GD lib that's the prob, but the flow of my sessions and could be some cofig problem in php.ini or apache's httpd.conf file.

Could you give me some light?

2 is a html page. Php runs in php pages.

if image.php is used to return an image, you can;t do a session_start as it will start header flowing and break the image.
It shouldn't matter that #3 is html, so long as no script is required inside the page itself.

Well, you all know that i can do my html like this:

</body>

So that's what i'm doing...

This has worked with my other server but is not operating right with my new local server...

Still in dim light...

unless PHP has been configured to process .html files, they will be html only.

.php goes through the php pre-processor, then the resultant html dumped by the web server whereas .html is just read and dumped. If the server is configured to process .html as php scripts, then all scripts will be run through the php engine before being output, which adds load on the server as it double-handles each page request.

Ok, i have reason to believe, you cannot use GD image functions with Sessions...

Hi Chris, you said >>.php goes through the php pre-processor, then the resultant html dumped by the web server whereas .html is just read and dumped. If the server is configured to process .html as php scripts, then all scripts will be run through the php engine before being output, which adds load on the server as it double-handles each page request.

How then would one have a nice template web design while implementing php? the way i am doing it is the traditional way i believe which is the main php page in root, and from the root calling html templates inside the templates folder...
in those html templates are $_POST variables that need to break out into php...

your insights please...

crazychris

so long as the page called is a php page, it can include php, html, whatever as it builds. If the initial page is html, then it isn't using php so won't be able to do anything.

a method like index.php?page=xxx where xxx is a page code to load the style/content and display it works, whereas index.html?page=xxx doesn't (or shouldn't)

re: "k, i have reason to believe, you cannot use GD image functions with Sessions..."

yep, as I said, do not do a session_start() as this will break the image script.

Hey thanks for having a flashlight in my dim hour...
