Question

I am trying to create gravatar auto load while user is writing his e-mail in a form field. Now, I’ve got php function, that will generate gravatar url with required paramaters and it work all over the website.

Now, when user types valid e-mail I should call jQuery:

image.attr("src", "<?=$this->Gravatar(" + input.attr('value') + ");?>");

But is this possible to pass this parameter to PHP function?

Answer 1

if I understood well you would like to do the following:

• User enters a vaild email
• Get the Gravatar from the PHP function without making an extrat request

You can’t really perform this without any request to the server, but you can make an easier way

prepare a gateway script to call your PHP function and send it a param with get
should look something like:

http://YOUR-FULL-URL/getgravatar?email=[e-mail]

than when the user enters an email you can get it this way

image.attr("src", "http://YOUR-FULL-URL/getgravatar?email=" + input.val() );

and like that you avoid using Ajax with a straight AJAX call
