Simple Sql Query Not Working

I am trying to get my search bar to search three fields from one table and if one of the fields from the three is matched, display the applicable field. I have the following code which should work.

$query_searchbar = "SELECT producttype, manufacturer, modelnumber FROM tblproduct WHERE producttype AND manufacturer AND modelnumber='$_POST[search]'";

This is my form which is running the code.

<form id="search" name="search" method="post" action="searchresults.php">   <input type="text" name="search" id="search" />   </form>

As the searchbar is in the header, I do not want a submit button, it runs by pressing enter.This is the entire page for the results page which is currently not displaying anything.

Write your conditionals out completely, and use OR instead of AND. All 3 of your fields won't be equal to your search term at the same time, right?$item = $_POST['search'];$query_searchbar = "SELECT producttype, manufacturer, modelnumber FROM tblproduct WHERE producttype='$item' OR manufacture='$item' OR modelnumber='$item'";I have not looked at the rest of your code. It might be a good idea to test your queries in a separate file that is as simple as possible.
