Hello coding legends,

Hopefully you can help me… I am trying to get my head around PHP and MySQL… I’m a bit of a beginner at all this.

I have constructed a MySQL database of musical artists who have achieved number one positions since records began in the UK.

The data is formatted as follows (quick example)

artist : Title : date : month : year
Rihanna featuring Calvin Harris : We Found Love : 18 : November : 2011

What I am hoping to do is have some code that can search my database when I submit a specific date (set in three parts day:month:year). I am aiming for the code to then bring back what artist/title of song was at number one on the queried date.

I seem to have ‘semi got there’ however when I select a date, it just brings every entry on the entire database back. It doesn’t filter it down to just the specific date I’m querying.

What I have done wrong/missed out/messed up? Your thoughts and help would be very much appreciated.



Code as follows…


if (!isset($_POST['Submit'])) {
// form not submitted

<form action="<?=$_SERVER['php_SELF']?>" method="post">

$query = "SELECT * FROM Top40 WHERE '$date $month $year=$search'" or die (mysql_error());

Is what you have wrong. Since each field is seperated, you'll have to do something like:

$query = "SELECT * FROM Top40 Where `date` = '$date' AND `month` = '$month' AND `year` = '$year'"

And I have no clue where the variable $search came from. hehe
