Hi friends............

I want to paginate my page but it not works properly.

It displays first 2 rows but on clicking "Next" nothing happens.

It displays error also "Notice: Undefined variable: PHP_SELF in C:\wamp\www\NGOProject\Elite Brigade\pagination.php on line 112" and "Notice: Undefined index: page_test.php in C:\wamp\www\NGOProject\Elite Brigade\pagination.php on line 124".........

I don't know what to do??????

Plz help me anyone???????

Work on your semantic errors before the logic errors (if any).

 

The first error tell you that you don't have a variable called "PHP_SELF" defined. You probably want $_SERVER['PHP_SELF'].

 

The second error tells you that $_SERVER['page_test.php'] does not exist, although $_SERVER definitely does.

 

To see the valid keys for the $_SERVER predefined variable, read through the documentation here: http://www.php.net/manual/en/reserved.variables.server.php

Boss I remove the syntax errors........but by commenting the PHP_SELF variable.

But logical errors remain still same.........

[seanlim]

the logic seems correct. check the links (view-source), make sure that they are properly formatted and links you back to the same script.

 

and please don't say it doesn't work without giving any description of your errors. what logic errors are you getting? page not showing? links not showing? when do they happen? after clicking which link?

[ankit.pandeyc012]

It displays first page well but the problem is on click "Next" or "Last" button nothing happens which I also mentioned in my quote............

Plz help............

what about that? are the links okay? i would help if you follow the suggestions provided and then provide your feedback on what happens when you try them. in this case, it would help if you tell me whether the links aren't malformed and whether there are any errors generated in the links.

[ankit.pandeyc012]

Dear I am not sure what you want to say???

On click any link same page refresh instead of showing next page.....

I think it is very little mistake which we not able to find......

Plz see the code and suggest something.............

[seanlim]

as i've said, your script looks logical. and there isn't anything wrong with it, assuming you've correctly fixed the previously mentioned errors.

 

okay, i'll make this really simple

 

1. LOAD the page

2. VIEW-source

3. LOOK at all the href attributes of the links i.e. <a> elements.

 

what do you see? is it "your_script_name.php?pagenum=2"?
