Here is the problem:
// at this time $s= 0, $limit=10, $pages=0.
// if(!((0+10)/10)==0 && 0 != 1) .... this mean that there is another
page...
if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {
$news=$s+$limit;
echo " <a href=\"$PHP_SELF?s=$news&search=$var\">Next
>></a>";
}
You should test if there's any results, if there's none then just skip all
other operations that are needed only if a match was found. Learn to use
if/else to avoid testing things you already know.
---------------
Your have useless code from the very begin:
if (!isset($var))
{
echo "<p>We dont seem to have a search parameter!</p>";
exit;
}
$var will always be set, you set it yourself, @$var = $_GET['search']
even if $_GET['search'] is not a valid array element.
Anyway it looks useless to me to tell visitors they don't entered nothing.
Take a look at google, just hit the search button without feeding it
anything ... it does nothing.
Basic Logic:
if(something was passed to search for){
do your search
if(there is result){
process them
}else{
no result;
}
}else{
nothing was entered ... no big deal, assume they just arrives.
}
I send a small rewrite of your code that solve your problem by applying
this logic. Anyway I didn't rewrite it scratch but only change things that
were broken.
