dynamically check field for value in mysql dbase

[tonynoriega]

i kind of touched on this before, but wasnt sure where to start.

i have a form that my agents fill out to enter new leads.

they want to be able to check if a record has been entered already by the leads last name...

so for instance, as they type in the last name, and either they tab out of the field or click out, it would query the dbase looking for that last name and display an alert....

is there a php snippet for this?

This is something you are going to need AJAX for. For a quick and simple example with php, refer to the following link as it is a very good start to understanding the concepts of AJAX:
