Meta Box

It works!!!!
I sincerely thank you and appreciate your patience, Long.
Have a nice night!

Hi Long,
It's me again and sorry for disturbing you too much.
I would like to ask could I use this way for a multiple select inside 2 levels of groups?

I have fields like this:

group1 (cloneable)
    |__group2 (cloneable)
        |__language (multiple select)

(language is inside group2, group2 is inside group1)

I used your hint

echo "<pre>";
print_r( $group_settings );
echo "</pre>";

and saw that I have to take out 2 'fields' of groups settings.

So I tried this code

$group1 = rwmb_meta( 'group1', ['storage_type' => 'custom_table', 'table' => 'custom'] );
$group1_settings = rwmb_get_field_settings( 'group1' );

foreach ( $group1 as $group1_value ) {
    $group2 = $group1_value['group2'];
    
    foreach ( $group2 as $group2_value ) {
        $multi_select = $group2_value['language'];
        foreach ( $multi_select as $select_value ) {
            foreach ( $group1_settings['fields'] as $group1_field_settings ) {
                foreach ( $group1_field_settings['fields'] as $field_settings ) {
                    foreach ( $field_settings as $setting_key => $setting_value ) {
                        if ( $setting_key == 'options' ) {
                            echo $setting_value[$select_value];
                        }
                    }
                }
            }
        }
    }
}

Unlucky me, I got error on the line
foreach ( $group1_field_settings['fields'] as $field_settings ) {

I'm so sorry, I'm bad at PHP. Please take a look a help me to solve this issue.

Many many thanks!

Hi Long,
Sorry for opening this topic again.

I have other select fields that are in a group field in a custom table. I edited your code to work in a custom table and a group field but I got some error warning and it didn't work

$group = rwmb_meta( 'group', ['storage_type' => 'custom_table', 'table' => 'custom'] );
$multi_select = isset( $group['language'] ) ? $group['language'] : '';
$select_settings = rwmb_get_field_settings( $group['language'] );
foreach ( $multi_select as $select_value ) {
    foreach ( $select_settings as $setting_key => $setting_value ) {
        if ( $setting_key == 'options' ) {
            echo $setting_value[$select_value];
        }
    }
}

I think I make something wrong on the line
$select_settings = rwmb_get_field_settings( $group['language'] );

But I really don't know what wrong. Please help!

Thank you!

Many thanks for your help, Long!

Hi Long,
Many thanks for your help!

I tried rwmb_the_value() and it worked great. Easy and fast. (Thanks again)

But for the fields with multiple choices, rwmb_the_value() always renders with HTML (which I don't want). So I tried the code rwmb_get_field_settings you gave me above:

$select = rwmb_meta( 'select_id' );
$select_settings = rwmb_get_field_settings( 'select_id' );
foreach ( $select_settings as $key => $value ) {
    if ( $key == 'options' ) {
        echo $value[$select];
    }
}

It works well with single choice select fields but seems like it doesn't work with multiple choice select fields.
I used the same code, only changed the field setting to multiple choices and it stopped working, with no "echo" info on the front-end.
If I change the field setting back to single choice, it works well as before.

So could you please give me a solution for a field with multiple choices!

Thank you!!

Many thanks for your clear explanation, Long!
Have a nice day!

Hi, thank you for your link. I read it but it is for showing all the posts and using a template which not what I need.

I need many views to show separate posts depend on many conditions. In this case, they are location and types of attractions (at least).

I use these views as a part in many pages and posts, not for a page with template layout. So I need shortcode of Views to put them in places I want.

For ex: I have attractions in Madrid, Paris, Rome... With the query above, I can show attractions for each city, not all attractions on one page. And I would like to have a map for each city as well.

Thanks
