Returning Specific Results after Search

SparkleD · August 30, 2007

Hi All,

I'm new to PHP. I have a properties database (MYSQL). When I click on a specific link, the results show all the properties in the database, however what I need the results to show is not all the properties but ones that meet a certain criteria. I want it to show the ones that are listed as "Rentals" only.

Any help is appreciated.

Well, without any code or database structure, its going to be hard to help you. However, if i assume that you have a field in your table(which im going to assume is called properties) called 'type', then its a relatively simply case of modifying your query to something along the lines of:

$sql = "SELECT * FROM properties WHERE type='rentals'";
$result = mysql_query($sql) or die(mysql_error());

sorry about that (and yes there is a property type field)...here is the code:
