MYSQL search

[besly98]

Hi All, i used this script for a search function.. .except the pagination doesnt work. Can anybody help me? what do i need to change?

 

<?php

 

  // 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 ** EDIT REQUIRED HERE **

mysql_connect("localhost","username","password"); //(host, username, password)

 

//specify database ** EDIT REQUIRED HERE **

mysql_select_db("database") or die("Unable to select database"); //select which database we're using

 

// Build SQL Query 

$query = "select * from the_table where 1st_field like \"%$trimmed%\" 

  order by 1st_field"; // 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>";

 

// google

echo "<p><a href=\"http://www.google.com/search?q="

  . $trimmed . "\" target=\"_blank\" title=\"Look up

  " . $trimmed . " on Google\">Click here</a> to try the

  search on google</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: "" . $var . ""</p>";

 

// begin to show results set

echo "Results";

$count = 1 + $s ;

 

// now you can display the results returned

  while ($row= mysql_fetch_array($result)) {

  $title = $row["1st_field"];

 

  echo "$count.) $title" ;

  $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=\"$PHP_SELF?s=$prevs&q=$var\"><<

  Prev 10</a>&nbsp ";

  }

 

// calculate number of pages needing links

  $pages=intval($numrows/$limit);

 

// $pages now contains int of pages needed unless there is a remainder from division

 

  if ($numrows%$limit) {

  // has remainder so add one page

  $pages++;

  }

 

// check to see if last page

  if (!((($s+$limit)/$limit)==$pages) && $pages!=1) {

 

  // not last page so give NEXT link

  $news=$s+$limit;

 

  echo " <a href=\"$PHP_SELF?s=$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>";

 

?>

whaqt i mean is that the pagination doesnt work. so you click fo rth enext 10 or 20 results.. but only refreshed the same page.. no extra pages...
