Hi,

I need to update group cloneable meta fields programmatically. So, that I can loop through an array and update the post meta fields.

Thanks in advance

Hi Manoj,

To update a cloneable group field, please use this snippet:

$values = [];
$values[] = [ 'sub_field_1' => 'value1', 'sub_field_2' => 'value2' ]; // Value of clone 1
$values[] = [ 'sub_field_1' => 'value1', 'sub_field_2' => 'value2' ]; // Value of clone 2

update_post_meta( $post_id, 'group_id', $values );

How do i Update just 1 field in a clonealbe group ?

Right now i use this code ud output data after submission:

$group_values = rwmb_meta( 'group_tapgyiu2mz', '', $post_id );
            if ( ! empty( $group_values ) ) {
                foreach ( $group_values as $group_value ) {
                 $rank = isset( $group_value[ 'ticket_rank' ] ) ? $group_value[ 'ticket_rank' ] : '';
                 echo $rank; // Display sub-field value  
                }
            }

            die();

That works fine

but then I want also to update a group field at the same time in the group.

add_action( 'init', function() {
    $post_id = 123;
    $field_id = 'group_tapgyiu2mz';
    $value = [
        [
            'hidden_field' => '1234',
        ],
    ];
    rwmb_set_meta( $post_id, $field_id, $value );
}, 99 );

Hi vacdk,

You need to get the group value first, access the element, and assign another value for this.

    $post_id = 123;
    $value = rwmb_meta( 'group_tapgyiu2mz', '', $post_id );
    $value[0]['hidden_field'] = '1234';
    rwmb_set_meta( $post_id, $field_id, $value );

Is this the same if it's a cloneable group ? as I can't get it to work. :/
where is it that I target the specified group field row in the foreach ?


add_action("rwmb_frontend_after_process", function ($config, $post_id) {
        if ("ticket-addon" === $config["id"]) {

        $group_values = rwmb_meta( 'group_tapgyiu2mz', '', $post_id );
            if ( ! empty( $group_values ) ) {
                foreach ( $group_values as $group_value ) {
                 $rank = isset( $group_value[ 'ticket_rank' ] ) ? $group_value[ 'ticket_rank' ] : '';
                 echo $rank; // Display sub-field value  

                 //$post_id = 123; <-- getting post ID from the add_action
                 $value = rwmb_meta( 'group_tapgyiu2mz', '', $post_id );
                 $value[0]['ticket_row_id'] = '1234';
                 rwmb_set_meta( $post_id, $field_id, $value );
                }
            }

            die();
        }
    },
    10,
    2
);

Hi,

If you get the group value above with this code

$group_values = rwmb_meta( 'group_tapgyiu2mz', '', $post_id );

please remove itself from the loop

add_action("rwmb_frontend_after_process", function ($config, $post_id) {
        if ("ticket-addon" === $config["id"]) {

        $group_values = rwmb_meta( 'group_tapgyiu2mz', '', $post_id );
            if ( ! empty( $group_values ) ) {
                foreach ( $group_values as $key => $group_value ) {
                 $rank = isset( $group_value[ 'ticket_rank' ] ) ? $group_value[ 'ticket_rank' ] : '';
                 echo $rank; // Display sub-field value  

                 //$post_id = 123; <-- getting post ID from the add_action
                 //$value = rwmb_meta( 'group_tapgyiu2mz', '', $post_id ); <--remove the duplicate code to get group value here
                 if( $key == 0 ) $group_values[$key]['ticket_row_id'] = '1234'; //update field ticket_row_id for the first clone group only, for example
                 
                }
            }
            rwmb_set_meta( $post_id, 'group_tapgyiu2mz', $value ); //move this code outside the loop because we need to update the group field with ID

            die();
        }
    },
    10,
    2
);
