Hello everybody,
I found paging code from www.plus2net.com, but when I implemented there is a problem with $this variable and the error is:
"Fatal error: Cannot re-assign $this in C:\wamp\www\Paging\php_paging.php on line 33"

This is the code:

It's because $this is a reserved word used with classes to reference the current object. For example

class TestClass
{
    var $blah;    
    function setBlah($input)
    {
        $this->blah = $input;
    }
}

thnx for that,
so what should I do? How should I do paging withing PHP, if possible plz descibe me more...

Thaks for the code,
There is no error on the code now, but when I click on the link navigation (1 2 3 4 next) nothing happen, doesnot go to the page I want...

hi.
1. First I open it, I just see the Link Navigation the even numbers mean (0 2 4 6 8 Next Next8)
2. When I click on any of the navigation link, I see the address bar like below:
php_pagin.php?start=2&p_f=0
php_pagin.php?start=4&p_f=0
php_pagin.php?start=6&p_f=0
php_pagin.php?start=8&p_f=0

means just in the address bar the number changes, nothing else happens in the page

i looked over the entire code line by line and really didn't see anything wrong. i took out all of the comments and stuff so i could read it better, made a few changes. i think it might work.

if it doesn't work i will probably make my own script that does work.

Really thanks for ur reply,
I used the code, but the system is not able to load the navigation part...I mean it is trying to load something in the page but not able...

If possible plz send me your own script, with comments coz I want to get fimiliar too, that would be very kind of you... Thanks

i set up a database to check the code and i think i fixed the problem.

yes, that is exactly what I want, but if there is first and last , that would be very nice...
Thanks much for ur accompany and helping...

first, thanks much for replying and helping again asn again, then everything seems to be work, but unfortunately when I click the navigatio link the address bar changes correctly, but the data not changed, means the data is the same in all pages...

first, thanks much for replying and helping again asn again, then everything seems to be work, but unfortunately when I click the navigatio link the address bar changes correctly, but the data not changed, means the data is the same in all pages...

i will solve it as fast a possible but more information on exactly what going on would be nice. maybe you could give me a link to the file on your server so i can see it for myself.

unfortunately, I am using Apachi on my own home pc, but ur code is working, means when I click on the links, the address bar changes, but the data on the page remains the same

yeah it is working on the link u sent me, but I did the same thing on my on pc, all is right, but the data not changed on page when clicking on the link...

so pretty much when you click a number the same 2 records are shown even though the url changes. i have no idea what would cause this. did you change anything in the code?
