Dealing With The Database: DELETE

In this block of code, we will delete a name from the table.

02. Our form is setup to have a "delete" link next to each name. You simply click on the link and the name is deleted. Since it's a link, we pass the name through the url via the GET method. So the first thing we do is check to see if that variable exists. If it does...

04. Once again we sanitize the variable.

06. We build the query string, inserting the name in the string with $name.

07. We send the string off to the database to be executed. Again, no reason to really assign the result to $result in this example.

We're using ODBC-connect, ODBC_exec, etc. How do I create a new record using ODBC? I don't imagine I can do it with mysql commands?

Well I don't really know anything about ODBC but they do have their own database handling functions in PHP that are very similar to all of the mysql_xxx counterparts. Here is a link to the functions php offers for ODBC: PHP ODBC functions

A kind of skimmed over the functions and it looks like all you really need to do is switch out the mysql_xxx functions with their ODBC_xxx counterparts.

All the code for the form and receiving info from the user etc.. would not need to be altered.

I knew that how to handle the database through PHP, but after reading this tutorial i think it's more than i think. It's really good. Thanks!

I've just started to learn how to use PHP with MySQL so this tutorial has been *very* useful!

I had already put together scripts and an html form to accomplish similar things to those shown in the tutorial but with the scripts in several seperate .php files. Having everything in one file makes much more sense!

Many thanks
