I am having trouble with a search engine I am making in PHP. I have a script that uses pagination to display 10 results per page and creates a next link to the next page of results. The problem is, is that there is no ranking that done it just puts whats in the first row of the table first and whats in the second row of the table second and so on and so forth. I tried using the LIKE operator withe my script that uses pagination but it does not work. Can some one please tell me how to rank the results and use pagination. Here is the search form
<form name="search" method="post" action="pagsearch.php">
<input name="q" type="text" id="q" size="35" maxlength="100">
<input type="submit" name="submit" value="Search">
</form>
and here is the PHP script
<?php
// Connects to your Database
mysql_connect("", "", "") or die(mysql_error());
mysql_select_db("") or die(mysql_error());
//This checks to see if there is a page number. If not, it will set it to page 1
if (!(isset($pagenum)))
{
$pagenum = 1;
}
//Here we count the number of results
//Edit $data to be your query
$q = mysql_query("SELECT * FROM `pages` WHERE (`description`) LIKE'%$q%';") or die(mysql_error());
$rows = mysql_num_rows($q);
//This is the number of results displayed per page
$page_rows = 10;
//This tells us the page number of our last page
$last = ceil($rows/$page_rows);
//this makes sure the page number isn't below one, or more than our maximum pages
if ($pagenum < 1)
{
$pagenum = 1;
}
elseif ($pagenum > $last)
{
$pagenum = $last;
}
//This sets the range to display in our query
$max = 'limit ' .($pagenum - 1) * $page_rows .',' .$page_rows;
//This is your query again, the same one... the only difference is we add $max into it
$q_p = mysql_query("SELECT * FROM `pages` WHERE (`description`) LIKE'%$q%' $max;") or die(mysql_error());
//This is where you display your query results
while($info = mysql_fetch_array( $q_p ))
{
echo "<br>";
echo "<span style=\"color:#0000CC; font-size:16px;\">";
Print $info['title'];
echo "</span>";
echo "<br>";
echo "<span style=\"color:#000000; font-size:14px;\">";
Print $info['description'];
echo "</span>";
echo "<br>";
echo "<span style=\"color:#00AA00; font-size:12px;\">";
Print $info['displayurl'];
echo "</span>";
echo "<br>";
echo "<br>";
}
echo "<p>";
// This shows the user what page they are on, and the total number of pages
echo " Page $pagenum of $last <p>";
// First we check if we are on page one. If we are then we don't need a link to the previous page or the first page so we do nothing. If we aren't then we generate links to the first page, and to the previous page.
if ($pagenum == 1)
{
}
else
{
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=1'><< First</a> ";
echo " ";
$previous = $pagenum-1;
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$previous'>< Previous</a> ";
}
//just a spacer
echo " ";
//This does the same as above, only checking if we are on the last page, and then generating the Next and Last links
if ($pagenum == $last)
{
}
else {
$next = $pagenum+1;
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$next'>Next ></a> ";
echo " ";
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$last'>Last >></a> ";
}
?>
NOTE:I took the host, username,password,database out of the script for security reasons.
