dynamic check of email address?

[wmguk]

Hi,

I'm looking for a AJAX dynamic checker that I can use to query a database for an email address.

I want to check if an email address is already in use, and I wanted to try it live... Does anyone have any starting points? I've googled dynamic checking etc, but couldnt find anything relevant.

Thanks

you would need to write a php script that did the checking then with the Javascript in the file reference the php page and return whether it (email address) was present in the database.


So you would need to create php page that connected to the database in question
performed a query to select the email address in question
then return true or false depending on whether the query was present
create some type of output page that parsed html onto the screen
create a javascript function that performed the check and outputted the results
