I started teaching myself PHP/mySQL a while back but then because of work and other obligations I had to take time off. I managed to create a form where martial artists register to compete in an event. The data collected by the form is then emailed to me and also stored in a mySQL database. I then made a page that displays the info from the database. The 1st page displays basic information on each martial artist (Full Name, Weight, Birthdate, Fight Record) then if you want to see all of the information that person filled out, you can click their name and it will open a page displaying everything that person filled out pulling that info from the database.

Here is the main page:


Here is what you see after clicking a name:


I want to create an admin page so I can edit the database and delete fighters if I need to...

Can anyone help or can you suggest any sites that may be able to help me?

I will throw this out and wait for yor questions:
To edit you need to pull the DB contents into a text box where you can edit it and write the result back to the DB.

Delete is a simple delete from where something (usually ID) = query.
Load a list of the fighters and have a script or routine to delete by id, name or whatever.

EDIT: Here is a sample delete routine where the category was selected from a drop down list:

$category=$_POST[category];
//echo $category; // debug only for the echo
$cmscategory="DELETE FROM cms_category WHERE category='$category'";
mysql_query($cmscategory);
