Hook reference with args

[lwoods]

What am I missing?  The Filter Reference in the Tutorials spells out the argument requirements but the Hook Reference does not.  Do I have to dig through the code to find what the requirements are for the hooks?
Thanks

Hi,
That's because there are any standard argument requirements for hooks. To me, a hook an area that developers have kindly provided for me to stick stuff into somewhere in the theme. That's an over-simplification, but is one way to look at it. So you set up a function that will do something "inside" that hook, and it could be just about anything.

Here's an example. The first thing may be useful, using the "genesis_before_loop" hook to pop the Featured Image above Post or Page content. And then just do demonstrate that this isn't strict, I put something asinine right after that. 🙂

add_action('genesis_before_loop', 'dc_put_in_featured');
function dc_put_in_featured() {
    if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it.
      the_post_thumbnail();
    }
    echo "Here's My Wonderful Sales Catchphrase!";
}

Duh!  Of course (I am just learning---obviously)!
Thanks for responding so quickly and clarifying.

Larry,
That's not a bad question at all - I didn't know how they worked at first. Just the fact that you want to use them puts you way ahead of many Genesis users, and you'll benefit for it.

I always like seeing example code, and then I'm on my way. I enjoy using this little beauty for knowing where the hooks are. And no, it's not Genesis 2 (soon to arrive), but understanding that will give you a leg up.

Brian's code will give many examples of hook in use, including some Genesis 2 stuff. WordPress has loads of standard hooks, too, and if you get that far, reading those in their documentation can be very helpful.

Have fun with the system! Dave

Thanks for the "little beauty."  I am using the "Genesis Visual Hooks" plugin and that helps a lot.  And, I have already used some of Brian's code in order to clean up some post meta.

Thanks, again.
