If your code is in the loop, code like this should work:
$custom = get_post_meta($post->ID,'my custom field',true);
if ( is_user_logged_in() && isset($custom) && strlen($custom) ) {
echo "your html table goes here";
}
If not in the Loop, put in the correct post ID.
Thanks.
I am not sure if this is overkill or bloated code, but I ended up going with this code.
I search for the current user, check to see if they are logged in, then return their i, then check to see if their custom field exists. if empty, I echo no html, if it does exist, I echo desired html.
global $current_user;
get_currentuserinfo();
$author_id = $current_user->ID;
$film_custom_field = get_field(‘film_1’, ‘user_’ . $author_id );
if ( is_user_logged_in() && empty( $film_custom_field ) ) {
echo ‘ ‘;
} else {
echo ‘html goes here’;
}
Your code may be perfectly correct, but I cannot vouch for that.
The get_field() function is part of the Advanced Custom Fields plugin. With the second parameter, the documentation says that it adds the field to the user. I am not certain what that means and what the return value will be.
I am guessing that this should work (without the need to get the current user info):
$film_custom_field = get_field('film_1');
if ( is_user_logged_in() && empty( $film_custom_field ) ) {
echo ' ';
} else {
echo 'html goes here';
}
Note that this will fail if the custom field ever contains only a zero or an empty string, because empty() returns ‘true’ for those values.
