Session variables apparently not doing what I want.

[stockton]

Within a intranet system I am building I have a PHP script(let us call it A) which generates a web page which on user input calls an Ajax script(we will call this B) to update the server based database with the values entered by the user. The update of the server based database is done via a PHP script(we will call this C) with no HTML. To make life a bit better I am using session variables to store data between calls to the database update script C.

This works perfectly the 1st time through but after the 2nd time around I find that certain session variables values have reverted to the values they contained before any processing was done. The scenario follows:-

Web page A is created via PHP containing data.

On user input Ajax B is "called" which calls C which returns to B which updates Web page A.

As follows B->C->B->update A->B->C->B->update A

I have been through my code a number of times and cannot see where this code could be reverting the data other than where I want it to.

Am I missing something?

I am on purpose not sending or including any code in case I am misunderstanding session variables or something equally silly.

Without seeing your code, it's hard to say.

 

But session variables should hold just fine from all your pages as long as you have session_start() as your first line.

[stockton]

I do have session_start() in both PHP scripts.

I do not mind sharing the source code.

Would you like me to send you the Javascript & database update PHP?

I do not believe that the PHP script that creates the page is in any way involved other than to create the page.

[aschk]

What you need to provide is

1) The original PHP page that display intial values and sets $_SESSION variables

2) The Javascript (Ajax) in your HTML file.

3) The PHP script that the Ajax is calling.

 

Post those here and we'll do our darnedest to help you out.

[revraz]

Or to do a quick test, just create 2-3 new .php pages.

 

Put $_SESSION_START(); at the top of all three and then just do

$_SESSION["test"] = "Hi";

 

Then on your other page do

 

echo $_SESSION["test"];

 

And see if you get "Hi" on your other two pages.  If so, then at least you have verified Sessions work properly on your webhost.

 

[stockton]

It is reasonably large but you did ask for it........:-)

The code that creates the page

I hope that the above all makes sense.

Without going through all that. Make sure ALL pages using sessions have a call to session_start() at the top.

well AJAX does have a caching problem at times so make sure your urls are different otherwise its will pick up cached data

rajivgonsalves, I have been under the impression that caching only came into play when a page was reloaded.

With Ajax reloading pages is redundant, or so I thought.

Please tell me if you feel that the code that I posted above might possibly have a caching problem and how I should fix it.

[rajivgonsalves]

well this is what I used

 

 

today = new Date();
cur_time=today.getYear()+""+today.getMonth()+""+today.getDate()+""+today.getHours()+""+today.getMinutes()+""+today.getSeconds();

if(xmlhttp.readyState==0 || xmlhttp.readyState==4)
{
	xmlhttp.open("GET", "index.php?module=Ajax&function=getCat&date="+cur_time+"&strCat="+strCat,false);
	xmlhttp.onreadystatechange = function handleResponse()

rajivgonsalves, I do not understand how your suggestion helps.

Please explain.
