PHP MySQL search not returning results

Question

I've created a php search script to search a MySQL database but no search is returning results.

Form Code

<form method="post" action="search.php">
<input type="text" value="Search..." name="query" />
<input type="submit" value="Find" name="completedsearch" />
</form>

PHP Script

<?php
                    if(isset($_POST['completedsearch']))
                    {
                            $term = $_POST['query'];
                            $mysql = mysql_connect("localhost","searchuser","password");
                            mysql_select_db("hcsd");
                            $qu = mysql_query("SELECT * FROM your_table WHERE COMPANY LIKE '%{$term}%' OR LOCATION LIKE '%{$term}%' OR KEYWORDS LIKE '%{$term}%' OR PRODUCTSSERVICES LIKE '%{$term}%' ");
                            echo "
                                            <th>Name</th>
                                            <th>Location</th>
                                            <th>Products/Services</th>
                                            ";
                            while($row = mysql_fetch_array($qu))
                                       {

                                            echo "<tr><td>";  
                                            echo $row['COMPANY'];
                                            echo "</td>";
                                            echo "<td>";
                                            echo $row['LOCATION'];
                                            echo "</td>";
                                            echo "<td>";
                                            echo $row['PRODUCTSSERVICES'];
                                            echo "</tr></td>";
                            }
                    }
            ?>

The MySQL database has 4 columns, headed COMPANY, LOCATION, KEYWORDS & PRODUCTSSERVICES, and this script should be searching any of the columns for the search term and then displaying COMPANY, LOCATION and PRODUCTSSERVICES for any matching rows in a table, yet even using search terms I know 100% are in the MySQL table, I'm still receiving no results.

Answer 1

I'm not sure the curly braces are helping here...

Replace

 $qu = mysql_query("SELECT * FROM your_table WHERE COMPANY LIKE '%{$term}%' OR LOCATION LIKE '%{$term}%' OR KEYWORDS LIKE '%{$term}%' OR PRODUCTSSERVICES LIKE '%{$term}%' ");

With

 $qu = mysql_query("SELECT * FROM your_table WHERE COMPANY LIKE '%".$term."%' OR LOCATION LIKE '%".$term."%' OR KEYWORDS LIKE '%".$term."%' OR PRODUCTSSERVICES LIKE '%".$term."%'");

You should escape the input as well

 $qu = mysql_query("SELECT * FROM your_table WHERE COMPANY LIKE '%".mysql_real_escape_string($term)."%' OR LOCATION LIKE '%".mysql_real_escape_string($term)."%' OR KEYWORDS LIKE '%".mysql_real_escape_string($term)."%' OR PRODUCTSSERVICES LIKE '%".mysql_real_escape_string($term)."%'");

Also consider using the more recent mysqli_ functions

Answer 2

What is the name of your table ?

You should try your request in phpmyadmin or anything software you use for manage your DB and see the results. If not result, there is probably an error in your request.
