Hello Chris,
I am inserting complete script for you to have a look at and was using
$s = $pages
// Get the search variable from URL
$var = @$_GET['q'] ;
$trimmed = trim($var); //trim whitespace from the stored variable
// rows to return
$limit=10;
// check for an empty string and display a message.
if ($trimmed == "")
{
echo "<p>Please enter a search...</p>";
exit;
}
// check for a search parameter
if (!isset($var))
{
echo "<p>We dont seem to have a search parameter!</p>";
exit;
}
//connect to your database **
mysql_connect("localhost","username","password"); //(host, username,
password)
//specify database **
mysql_select_db("_database") or die("Unable to select database"); //select
which database we're using
// Build SQL Query
$query = "select * from mytable where massage like '%".$trimmed."%' order by
id";
// EDIT HERE and specify your table and field names for the SQL query
$numresults=mysql_query($query);
$numrows=mysql_num_rows($numresults);
// If we have no results, offer a google search as an alternative
if ($numrows == 0)
{
echo "<h4>Results</h4>";
echo "<p>Sorry, your search: "" . $trimmed . "" returned zero
results</p>";
}
// next determine if s has been passed to script, if not use 0
if (empty($s)) {
$s=0;
}
// get results
$query .= " limit $s,$limit";
$result = mysql_query($query) or die("Couldn't execute query");
// display what the person searched for
echo "<p>You searched for :<font color=blue size=+2> "" . $var .
""</font>";
// begin to show results set
echo " found $numrows results <p>";
$count = 1 + $s;
// now you can display the results returned
while ($row= mysql_fetch_array($result)) {
$title = $row["sname"];
$url = $row["url"];
$message = $row["massage"];
// <a href=\"$row['url']\">"$row['sname']</a><br />
$row['massage']<br><hr>'\
echo "$count.) ";
echo "<b><a href=\"$url\" target=\"_blank\">$title</a></b>";
echo "<br>";
echo "$message<br><hr height=12 color=lightblue><br>";
$count++;
}
$currPage = (($s/$limit) + 1);
//break before paging
echo "<br />";
// next we need to do the links to other results <<
if ($s>=1) { // bypass PREV link if s is 0
$prevs=($s-$limit);
print " <a href='{$_SERVER['PHP_SELF']}?s=$prevs&q=$var'> <<<
Prev 10</a>  ";
}
// calculate number of pages needing links
// $s=intval($numrows/$limit);
$s=ceil($numrows/$limit);
// $s now contains int of pages needed unless there is a remainder from
division
if ($numrows%$limit) {
// has remainder so add one page
$s++;
}
// check to see if last page
if (!((($s+$limit)/$limit)==$s) && $s!=1) {
// not last page so give NEXT link $PHP_SELF >>
$news="$s+$limit";
echo " <a href='{$_SERVER['PHP_SELF']}?s=$news&q=$var'>Next 10 >>>
</a>";
}
$a = $s+$limit;
if ($a > $numrows) { $a = $numrows; }
$b = $s+1;
echo "<p>Showing results $b to $a of $numrows</p>";
include ('footer.inc');
