Hi Long,

I am struggling with groups again. I have tried to use the documentation on this page. I am getting a fatal error with the following. What am I doing wrong?

add_action( 'transition_post_status', 'invite_email_sent_to_coauthor', 10, 3);
function invite_email_sent_to_coauthor( $new_status, $old_status, $post ) {

$co_author_group = rwmb_meta( 'academicadd_co_author' ) ?: []; //this is the group field id
foreach ( $co_author_groups as $co_author_group ) {
$send_email_y = $co_author_group ['academicco-author_lead_yn'] ?? '';  //this is the id of a field within the group field
$coauthor_email = $co_author_group ['academicco-author_email']  ?? ''; //was I supposed to include this part: ?? '' or replace it with something? 
$academic_name = $co_author_group ['academicco-author_full_name']  ?? '';
};

if (( $new_status == 'publish') && ($old_status !== 'publish') && (get_post_type( $post ) == 'research') && (!empty($coauthor_email)) && ($send_email_y == 'y')));
{.... }

Hi,

Can you please share the fatal error message? You can pass the post ID to the helper function to get the field value. For example

$co_author_group = rwmb_meta( 'academicadd_co_author', '', $post->ID );

And I just tried $co_author_group = rwmb_meta( 'academicadd_co_author', '', $post->ID ); but got the same error too!

A follow up question - in my IF statement, where I want to check a custom fields value is equal to 'y'. Have I done this correctly? I have another piece of code and it works when I don't query against the value of a custom field, but when I try to query that it equals a custom field value it returns and does not execute my code (even though I checked and the value is definitely correct)

Hi,

It looks like there is an issue with your custom code, not with the helper function rwmb_meta(). If you want to do a customization job with an extra fee, please contact us via this form https://metabox.io/contact/, our plugin will help you to do that.

Ok Long, thank you for the clarification.

And my second question - how do you add custom fields to if statements?

Can I do it like:
```
$co_author_email = rwmb_meta( 'academicadd_co_author', '', $post->ID )

If ($co_author_email == 'y')
```
This is for something else, and the code works perfectly if no custom field conditions in the if statement, but then adding custom field conditions into if statements stops it from executing, even though the value is definitely there

Hi,

Which is the field type add_co_author? If it is a simple text or select field, you can check the field value as well. And please correct the if statement, i should be in lowercase.
```
$co_author_email = rwmb_meta( 'academicadd_co_author', '', $post->ID );

if ( $co_author_email == 'y' ) {
    echo "Yes";
}
```

Hey long, the field I am actually having issues with is a radio field with the values 0 and 1.

I was trying with rwmb_meta in exactly the format you share, however I thought maybe I should be using a different filter

```
$checked_box = rwmb_get_value('hidden_published_already', '', $post->ID );
if (( $new_status == 'publish') && ($old_status != 'publish') && (get_post_type( $post ) == 'research') && (($checked_box == 'Not published') || ($checked_box == 0))){ ..}// 0 is the value of unpublished
```
This is what I have. It either works, or it doesn't work. It doesn't work if I use === 0, but it does work if I use ==0. The issue is, using == 0 also means it fires when the value is 1

Sorry in above it just shows the different filters I tried. Also tried:
```
$checked_box = rwmb_meta('hidden_published_already', '', $post->ID );
if (( $new_status == 'publish') && ($old_status != 'publish') && (get_post_type( $post ) == 'research') && ($checked_box == 0)){
```

Oh I think I worked it out - the above was my first attempt using the label, not the value - and I think that is what was wrong!
