Odd functions.php issue in Wordpress

Question

I'm using More Fields plugin, and when I use my functions.php to embed the custom field, I get an odd issue. The field value is followed by a "1"

I use this code:

//Address
add_action( 'woo_post_inside_before', 'my_address' );
function my_address() {
    global $post;
if ( is_single() && in_category('listings') ) { 
        echo more_fields('address', '<h1>','</h1>');
       }
}

But, if I use the following code - their is no "1"

//Address
add_action( 'woo_post_inside_before', 'my_address' );
function my_address() {
    global $post;
if ( is_single() && in_category('listings') ) { 
        echo meta('address');
       }
}

How do I style the above using the echo meta? Or has anyone ever seen the "1" issue?

Answer 1

There is no WordPress function called meta(). Try using get_post_custom() (Codex ref) instead. For example:

//Address
add_action( 'woo_post_inside_before', 'my_address' );
function my_address() {
    if ( is_single() && in_category('listings') ) { 
        global $post;
        $meta = get_post_custom();
        echo '<h1>' . $meta['address'] . '</h1>';
    }
}

Note: I'm not sure you need to call global $post; in this context?

EDIT: updated to add HTML tags.

more_fields() already echos the output for you, you don't have to do this yourself. It returns a boolean indicating whether it could output anything, which is converted to 1 when you echo it.

So just call more_fields(), not echo more_fields() to get the output you want.

This is a hunch because I do not know that plugin, your adding styling tags into the parameters of that function, I doubt that is possible (it might be though).

What happens when you use echo more_fields('address')

What about echo "<h1>" . more_fields('address') . "</h1>";

Or even better:

<h1> <?php more_fields('address'); ?> </h1>
