I am looking for a way to write a condition for a subpage...in other words

if we're on the subpage "duck" then do something...if not do something else.

I found some code I thought would work, but it shows up on all of the pages under a given parent page, not just on its individual page...I'm only trying to target the individual page.

This goes in functions:

// Subpage Shortcode
function is_child($page_id_or_slug) {
    global $post;
    if(!is_int($page_id_or_slug)) {
        $page = get_page_by_path($page_id_or_slug);
        $page_id_or_slug = $page->ID;
    }
    if(is_page() && $post->post_parent == $page_id_or_slug ) {
        return true;
    } else {
        return false;
    }
}

This is my if:

if (is_child("Youth")) {
    echo "duck";
} else {
    echo "something else";
}

Thanks,
Josh

Hmm, I'll take a crack at this. There's a few ways to go about this. Check to see if page is a direct child, check if it is an ancestor.

Something like below might work for you

if (283 == $post->post_parent) {
echo 'this post has a parent of 283 so do this';
}else {
    echo "or do something else";
}

Alex, I have more than one child page...which is why the current code doesn't work...is there any way to make your code work for multiple subpages? –  Josh Rodgers Jan 30 '13 at 22:13
    
To make sure my understanding is correct. You want to "do something" on all children of a specific Parent Page. Right? If so then this should work if(is_page() && $ancestor == $pid) { "do this"; }else{ echo "do this instead"; } That should fire off if you're on a page and that page is an ancestor of $pid where it's the page id –  Alex V.

Alex, I have a main page called "People" then I have subpages or child pages called "Oscar", "Billy", and "Tim"...right now my code displays on all three subpages "Oscar", "Billy", and "Tim". I would like it to display on "Billy" only, if that's possible :) sorry for the confusion. –  Josh Rodgers Jan 30 '13 at 23:58
    
This code would only run on a page with a post named 'Billy' 'if (is_page('Billy')) { echo "do this"; }else{ echo "do this instead"; }' –  Alex V. Jan 31 '13 at 0:30
    
Alex, I don't have a post named "billy", I have a child page named "billy" :-( –  Josh Rodgers Feb 1 '13 at 20:52

I don't know what I was thinking earlier...I guess somehow I was thinking that is_page wouldn't work for my child page, but I was over-thinking...this is my final code:

<?php if (is_page("duck")) { 
    echo "do something";
} else { 
    echo "something else";
} ?>

I know, I know it's so simple, but it works - guess I was just having a brain fart.

Thanks,
Josh
