Instead of creating a whole new database just create a table in the existing WordPress database. Then all you will need is a customized page template with the drop down and the technique discussed in the article will work like a charm.

I am currently running a website for my athletic club and I have created a separate database which will hold results. I wiuld like to go to a webpage and from a drop down box select the race and the results will be populated below on the same page. You dont need to be logged on as i want this available to everyone..

Its driving me crazy at the minute so I would appreciate any help

thanks

@Green C – all you have to do is include the core Wordpres files

include_once(‘wp-config.php’);
include_once(‘wp-load.php’);
include_once(‘wp-includes/wp-db.php’);

at the top of your external script and then declare Global $wpdb and off you go. I didn’t ultimately use this technique, as mentioned in the aticle, so I can’t vouch for it.

To see if it will work set up a php script, include the WordPress core files, and then see if you can access $wpdb by echoing a property to the page. Eg.

echo $wpdb->prefix

I am in the similar situation as you. I want to use $WPDB class outside WordPress context in an external Ajax handling script. I need to transfer, using ajax, back and forth data as Json.Can you make your post more detailed, maybe give an example.Thx.

I’m not sure I understand the question. To implement new ajax functionality you will have to write some code and hook it to Wordpres. The plugin mechanism is the way to do that.

Ajax is simply a technique of getting or sending data from or to the server without reloading the page. WordPress itself is chock full of ajax functionality.

The only way I am aware to add custom functionality to WordPress, ajax or otherwise, is by modifying a theme or writing a plugin.

Is there any way to do ajax in wp without building a plugin (which seems kinda redundant)?
