IF logged in, can add notes to images, ELSE can't. (?)

in Using jQuery • 11 years ago

I'm looking at some jQuery plugins/scripts that allow a person to add notes to images, but the downside is that anybody viewing the site can add a note that is vulgar or meaningless.

It seems like there is probably an easy way to combine jQuery with PHP to recognize if the Administrator is logged in and, if so, allow him to annotate images.

Can anyone help me figure out how to begin?

Thanks!

(This is my first post here and my first attempt at modifying jQuery plugins to do what I want)

You would do this on the server-side in your PHP. Only include the annotation functionality if the user is the administrator.

Thanks, I was thinking it was that. Unfortunately, I'm just getting started with both PHP and jQuery. I know a little more about PHP, but not enough to figure this out on my own.

I'm going to guess that Wordpress, for instance, has some php in there that says IF logged in then some value = 1 (for true) and then in your jQuery you'd somehow go check it that variable was 1 (true) or not.

Makes sense, right? I think I got the thinking figured out, just not the coding. I was hoping someone else must have already done this and could show me an example of how it's done.

Thank you for clarifying it for me to the extent you did!

No, what you need to do is determine if the user is admin in the php, and if so add the jquery.

As you mention wordpress, here is a specific wordpress example:

<?php
if( current_user_can( 'manage_options' ) ) {

// Do something, for admins only,
// eg add your jquery plugin reference

}
?>

You could place this in your header.php file.
What it does is check the current users capabilities (a wp function - follow the link for more info), and if they can 'manage_options' (only something an admin can do) then it exectues whatever you put in the curly braces.

So for example you could reference the necessary jquery file there.
