Um, have you tried $_POST[‘new_field’] yet?

(Don’t forget to sanitize the user input before you run ANY query. See $wpdb->prepare here: https://codex.www.ads-software.com/WordPress_Coding_Standards.)

Do a bit of basic debugging…

$postKey = get_post_custom_values('RotatingPostCover', $post->ID);
and

echo "ID=[". $post->ID . "]";
var_dump($postKey);

will tell you what is stored there, what the ID was that you though you had, and why you’re getting nothing. Sometimes it’s caused by some other code that ran earlier, changing your $post. Or maybe the first instance of your custom field is blank.

src=’Array’ means $postKey is an array.

Sometimes the output is an array. If you want a list, use the foreach loop:

https://codex.www.ads-software.com/Function_Reference/get_post_custom_values

Or if you just want the first, use the older function:
$postKey = get_post_meta('RotatingPostCover', $post->ID, true);

@marcomail, we’re talking about a posts query. comments.php is only supposed to display comments, not posts. Look in single.php. That page typically includes comments.php, so on a single post page, it uses the $wp_query->comments list to display the comments for the related post.

If you’re writing a custom query (like the posters above), then we’re explaining that you need to restore the default $wp_query global variable, otherwise your comments_template() function call will use the most recent query data, and display the wrong comments or none at all.

I hope that’s why you asked your question.

BTW there is a have_comments() loop, but for comments.php customization you should stick with the default comments.php and just use CSS, or make a custom Walker class if you like to dig into PHP.

@anoopu: I see you’ve made several posts (which is good, since this thread is not the right place for a new topic), none answered… (which suggests you need to provide more – a lot more – detail). You may want to try searching, or provide more detail in the thread you started under “Plugins and Hacks”.

For that suburbview.com (and similar sites), all it needs to do is read the syndication feeds (ie Trulia or Zillow) from a Great-Real-Estate enabled site. Both feeds are similar. (Google base is a bit different, but another option too).

You’ll need to trace back the order of execution; you’re right, it certainly does matter, at least in WordPress. (Sorry, there are enough “I pasted this stuff together why doesn’t it work” questions lately… seems nobody wants to go and read the PHP man pages)

For tracing the sequence of events, aside from the php files themselves, this resource might be helpful: https://adambrown.info/p/wp_hooks/version/2.7. There can be many reasons leading up to a particular action or filter being triggered… enough that I tend to favor the “go back and collect the data when it’s needed” method – even if it means an extra db query or two – instead of the “I just published a new post so let’s increment counter X” approach. Good luck.

@lakong – please don’t bump

Did you ever declare this variable outside of the scope of a function?

Sounds like a php issue. The answer here: https://us2.php.net/global

Try this:
https://www.ads-software.com/support/topic/183165

At some point that global needs to have something assigned TO it. Did you simplify that out?

Shouldn’t be an issue, as long as your server is properly configured. Try loading archive.php directly using the path (ie /wp-content/themes/foo/archive.php) and then view source. You should either get an error, or not much of any use. Only someone with login access to your machine would see them.

If you want to make it more complex, and you know their user ids or logins, you could use that instead of user_email.

@southbound…

Two tips for digging into WordPress core:

1) Google “wordpress functionname” and look for a phpxref site. Usually these cross-references will show which core file the function is in (then it’s a simple matter of opening the file up from your site) and all the calling files (to see how it’s used) and then a link to source code. (You seem to have already perused the get_categories() code)

2) When writing code, if it’s hard to work out what WordPress is giving you in a function return (because there are many levels of functions, etc) add print_r($result); to your code and look in your browser for a dump of the array or object.

So try

$whoknows = get_categories();
print_r($whoknows);

to see what you get. Hopefully it’s useful.

Unfortunately the Taxonomy stuff is fairly complex.

@modelcitizen – no search options yet. It’s more designed (in the current version) for listing agents to showcase a handful of listings.

You should find some filter docs (and the actual source code) here:
https://adambrown.info/p/wp_hooks/version/2.7

https://codex.www.ads-software.com/Function_Reference/wp_get_current_user

then use (after you set up $current_user per the example)

<?php
$message_users = array('[email protected]','[email protected]');
if (in_array($current_user->user_email, $message_users)) {
?>
   <h2>Hi Folks!</h2> ... etcetera
<?php
}
?>

Keep in mind that codex doc is incomplete, there are some defined functions that are easier to use in templates, such as is_user_logged_in() and if you’re going to use this a lot you might want to create a function such as is_user_email($email_list) and put it in your theme’s functions.php file so your templates are cleaner.

function is_user_email( $email_list ) {
    global $current_user;
    get_currentuserinfo();
    if ( !is_array( $email_list ) ) {
        $email_list = array( $email_list );
    }

    return in_array( $current_user->user_email, $email_list );
}

This function will also handle a single email, such as
if ( is_user_email('[email protected]') ) { ...

If you prefer, you can test against user_login instead of user_email.
