$_server[php_self]
You can do it without writing.

$_server[php_self]
Do not write can also be the two lines inside the $php_self? I deleted the next page after clicking on the "Can't find this page" ...

I waited until yesterday to wait until today.

You should at least post the modified code!

You should at least post the modified code! The main problem is I will not modify it ~ ~

Since you're not going to change, where's the "Can't find this page"

Well, I lost to you. I just put 71, 79 lines of $php_self? deleted and then run.

Since you're not going to change, what's the "can't find this page"? How did it become a line? I re-stick

You should at least post the modified code! By the way, I need to explain that my $list_num has been defined in advance.

You can do it.
Print ("next page");
Say it's $php _self can not
But you
Print "Previous page";}
Even? And no more.

Then I'm going to change it to print "previous page";} and print ("next page");
After the addition, to is no error, but the next page is the first page of content AH ~ ~ ~

I do not know who taught you to use error_reporting (e_all ^ e_notice); Avoid the contradiction
This is irresponsible!
Where does your $offset assign value?
Since you do not have $offset = $_get[' offset ';
So how can the target offset be passed in?
Since can not pass, that page how to achieve?

Now that you have extract ($_request);
Then $offset = $_get[' offset '); No need, let alone if it is a post form submission, there is no $_get[' offset '

You are under PHP5 to debug a project that is written according to PHP4 General work environment, then there are certain problems.
But you don't actually have the ability to modify the code, which can be seen from the problem of not resolving undefined variables.

In your first few posts, I have clearly told you: at the beginning of the program to add extract ($_request); You can do it.
The purpose of this is to: in the absence of magic variables, using the PHP4 project

As for the $php _self problem of this round, obviously you made it yourself!
If it is the original, then it is $PHP _self rather than $php _self (note: PHP variable name is case-sensitive)

You will not only look at the code, but also look at people, but also you bother to write such a large section to teach me. I, I, I really was too touched!!!

Since you already have extract ($_request);
Then $offset = $_get[' offset '); no need, let alone if it is a post form submission, there is no $_get[' offset '

in your first few posts, I have explicitly told you: Add extract at the beginning of the program ($_request); it's fine.

As for this round of $php _self problem, obviously you made it!
If it is the original, then it is $PHP _self instead of $php _self (note: PHP variable name is case-sensitive) moderator, because of my level and grade problem, again and again very annoying every day in the forum to ask some mentally retarded questions, this is my graduation design, Was forced to have no way, around the classmate also did not PHP, in June 2 good defense before, the young woman may also bother you many times, hope you forgive me!
