[RESOLVED] PHP Help - I must be over looking something

jdk · 07-30-2007, 12:56 PM

I have been staring at this since last night and for some reason I must be overlooking something. I have had no problems in the past but for some reason this one is has me stumped.

Code removed b/c project has not officially been released I am working on.

Replace this line

PHP Code:

                                      $pageprev = $page=$page-1;

With this

PHP Code:

                                      $pageprev = $page-1; 

????: NamePros.com http://www.namepros.com/programming/355881-php-help-i-must-over-looking.html

and

PHP Code:

                                      $pagenext = $page=$page+1;

With this

PHP Code:

                                      $pagenext = $page+1; 

????: NamePros.com http://www.namepros.com/showthread.php?t=355881

In both cases you're inadvertently setting $page in the code along with $pageprev and $pagenext.

Note that the second case ($pagenext) doesn't manifest an error for you because you no longer access the $page variable after that code. But it's a logic error nonetheless, and one day you might just need to access $page somewhere after creating the prev/next links.

Thanks I also had to remove the

PHP Code:

  $page++;

I must have added in there.

Ah yeah. I commented that out in the test code as well and forgot to mention it.
