  1. It works other then the fact it won't go to another page to see results.

     

    <?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");

    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>";
    
    ?>
