    I believe that noone can answer you this question. Even with lots of experience in php/mysql programming one would need to analyze your script and database data to see why the script doesn't return any results.
    Try a step by step debugging: insert a series of echo... / exit; in various parts of your script to be able to see the flow and check if the cortect parameters / variables are passed through all parts of the script.

    Sometimes, even a white space by mistake added to the databased stored info, could be enough to create such problems.

    index.php
    File Type: PHP script text

    This is the php page: www.onitshabusinessdirectory.com/searchproduct.This is the script after succefull connection to the database and the databatable:

    //specify how many results to display per page
    $limit = 10;
    // Get the search variable from URL
    $var = @$_GET['q'] ;
    //trim whitespace from the stored variable
    $trimmed = trim($var);
    //separate key-phrases into keywords
    $trimmed_array = explode(" ",$trimmed);
    // check for an empty string and display a message.
    if ($trimmed == "") {
    $resultmsg = "<p>Search Error</p><p>Please enter a search...</p>" ;
    }
    // check for a search parameter
    if (!isset($var)){
    $resultmsg = "<p>Search Error</p><p>We don't seem to have a search parameter! </p>" ;
    }
    // Build SQL Query for each keyword entered
    foreach ($trimmed_array as $trimm){
    // EDIT HERE and specify your table and field names for the SQL query
    $query = "SELECT * FROM onitsha_product_directory WHERE business_location LIKE '%$trimm%' OR type_of_location like '%$trimm%' OR type_of_business like '%$trimm%' ORDER BY id DESC" ;
    // Execute the query to get number of rows that contain search keywords
    $numresults=mysql_query ($query);
    $row_num_links_main = mysql_num_rows ($numresults);
    // next determine if 's' has been passed to script, if not use 0.
    // 's' is a variable that gets set as we navigate the search result pages.
    if (empty($s)) {
    $s=0;
    }
    // now let's get results.
    $query .= " LIMIT $s,$limit" ;

    $row= mysql_fetch_array ($numresults);
    //store record id of every item that contains the keyword in the array we need to do this to avoid display of duplicate search result.
    do{
