Need code to find last page, and help passing all form variables

HexKrak

I need to be able to make some sort of php function to pull up the last page viewed so I can pass form varaibles to it etc, so the javascript function go.history(-1) wont work for this situation. After diving thru the php function dictionary for hours on end I'm at a loss for where to look, or what to look for.

Also I was wondering if anyone knew an easy way to pass all form variables on to the next page rather than forwarding each manualy. This isn't all that important, but would make the code more efficiant.

I believe $_SERVER['HTTP_REFERRER'] does this no?

From the manual:

'HTTP_REFERER'

The address of the page (if any) which referred the user agent to the current page. This is set by the user agent. Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted.

As to pass the variables from a form, you can loop through the POST global variable since it stores the data into an array.

That should do it, thx much, I dunno why I didnt see that in the manual myself, I was searching $SESSION, and $SERVER variables extensivly.

Also is there a way to submit a form using php? I can't seem to find a funtion for that either.

Well, you submit the contents of the form by <form method="POST" action="whatever.php"></form>

I meant like the javascript function document.form.submit() only for php, something I can execute in my script to submit form data.

the only way to autosubmit a form is to use javascript. php is server side and has no control over anything the client browser does once the page loads.

I dont need it to be done clientside, I just need to have a script that will pass on form variables and thus header("location") wont work for my purposes. Right now I'm using onload='document.form.submit', but I was hoping there was a way to do this using php, if there isnt I'll just continue using the jscript.

correct, there is no way to have php automatically submit a form. js is the only way to have the form submit. you can use php to formulate an http post and submit the data using sockets or curl and then read back the response, all while the user sits there with all of it happening behind the scenes.
