I'm afraid I still don't understand. I think you are seeing something
that I don't see. What do you mean by link in the present context... are
you talking about some snippet of code equaling each page or every page
in the db? This is an ever growing db.
Anyway, I finally found the error of my ways (at least in this code). It
may look sloppy, but then I haven't looked that hard for other examples.
Some I found were too simple, others too bloated.
At least, this one works for what I need and does exactly what I wanted.
:-)
Here's the final fixed code; some obvious (I hope) variables are left
out and precede the code:
echo (($page !=1)?"<a href='".build_url("books.php", "page",
1)."'>first</a>":"first")." ... ";
echo (($page>1)?"<a href='".build_url("books.php", "page",
$page-1)."'>prev</a>":"prev")." | ";
for($i=$page; $i<=($page+$records_per_page-2)+1; $i++){
if ($i>ceil($count/$records_per_page))
continue;
elseif ($i!=$page)
echo "<a href='".build_url("books.php", "page", $i)."'>$i</a>", " | ";
else
echo $i, " | ";
}
echo " ... ".(($page<ceil($count/$records_per_page))?"<a
href='".build_url("books.php", "page", $page+1)."'>next</a>":"next");
if ($page==ceil($count/$records_per_page))
echo " ... last";
elseif ($i!=ceil($count/$records_per_page)) echo " ...
".(($page<ceil($count/$records_per_page)+$records_per_page)?"<a
href='".build_url("books.php", "page",
ceil($count/$records_per_page))."'>last</a>":"last");
else echo " ... ".(($page<$count)?"<a href='".build_url("books.php",
"page", ceil($count/$records_per_page))."'>last</a>":"last");
echo "<br>Ordered alphabetically by book title : ";
echo $dir=="ASC"?"Ascending":"<a href='".build_url("books.php", "dir",
"asc")."'>Ascending</a>";
echo " | ";
echo $dir=="DESC"?"Descending":"<a href='".build_url("books.php", "dir",
"desc")."'>Descending</a>";
If there is a way to simplify things, please do let me know (with an
example, please)
