Meta Box

I think the best way to do that is via CSS. You can install a plugin like Add admin CSS. The CSS to make each label display in ins own line is quite simple:

.rwmb-radio-wrapper .rwmb-input > label {
  display: block;
}

If you don't want to use a plugin, you can enqueue a CSS file on Add new/Edit page with the same snippet above.

This way you also can add more margin to label for a better look.

But if you have to use PHP to output line break after each label tag, please use rwmb_radio_html filter, like this:

add_filter( 'rwmb_radio_html', function html( $output, $field, $meta )
{
	$html = array();
	$tpl  = '<label><input type="radio" class="rwmb-radio" name="%s" value="%s"%s> %s</label>';

	foreach ( $field['options'] as $value => $label )
	{
		$html[] = sprintf(
			$tpl,
			$field['field_name'],
			$value,
			checked( $value, $meta, false ),
			$label
		);
	}

	return implode( '<br>', $html );
}, 10, 3 );

Hi Jon,

Sorry for late reply, I just back again and wonder to see that you can fix your code easily, brilliant.

I can see you set 'column' => 4 for some 'hidden' fields, it's not necessary as these fields are hidden and some repeated code can be rewrite to cleaner 😉

All foreach like so:

...
foreach ( $_POST as $key => $value )
{
	if ( strpos( $key, 'p52_quote_phone_' ) )
		unset( $_POST[$key] );
}
...

Can be combine and rewrite to 1 foreach like so:

foreach ( $_POST as $key => $value )
{
	if ( strpos( $key, 'p52_quote_phone_' ) || strpos( $key, 'p52_quote_company_' ) || strpos( $key, 'p52_quote_delivery_address' ) ... ) // Replace ... with all fake fields you've set
	unset( $_POST[$key] );
}

For cloned group, I firstly designed for 1 product only and if we switch to cloned groups, it's time consuming because it's related to populate custom data and out of our scope, we're sorry about that.

Best Regards

Tan

Hi Jon, it's really weird if it return empty value even though customer phone has set. Can you please give me credentials to your website to check? Include FTP and WP-Admin? Can you send me via my email to check it faster? My email is: [email protected]

Oh, sorry, remove the square bracket and keep it $meta_box because I have assign $meta_boxes[] = $meta_box later 😉

Hi Jon, I found another problem on your code:

// start customer
$meta_boxes[] = array(

You can remove [], it just $meta_box.

On step value, can you please change to full value contains zero sign, 0.01 instead of 'step' => .01?

If you still get error, try to comment out some other Meta Box (I though is Groups), to check what meta boxes generate error 🙂

Hi carassius

To explain it more clearly, I've basically created two fields, as defined in this array:

'fields' => array(
			array(
				'name' => 'Name',
				'id' => $prefix . 'name',
				'type' => 'post',
				'post_type' => 'customer',
				'placeholder' => 'Select a Customer'
			),
			// Real field
			array(
				'name' 		=> 'Phone',
				'id' 		=> $prefix . 'phone',
				'type' 		=> 'hidden'
			)
		)

There're two fields called p52_quote_name which type is is post and p52_quote_phone which is hidden field, this field will hold the real value. ($prefix = 'p52_quote_' as you defined)

I've also created a bunch of input text fields, each field has ID: p52_quote_phone_$customer_id which customer ID is the post ID, and the default value is the customer phone, as this snippet:

foreach ( $customers as $customer )
	{
		// Show this phone field if match name.
		$meta_box['fields'][] = array(
			'name' 		=> 'Phone',
			'id' 		=> $prefix . 'phone_' . $customer->ID,
			'type' 		=> 'text',
			'std' 		=> get_post_meta( $customer->ID, 'p52_quote_phone', true ),
			'visible' 	=> array( $prefix . 'name', $customer->ID )
		);
	}

You can see

'visible' 	=> array( $prefix . 'name', $customer->ID )

That means, visible this field, when the select customer name is equal to customer ID, that means if we have two persons with phones, for example called:

ID 1: Jim : 0123456789
ID 2: Kane: 0139401451

So, if Jim, ID 1 (p52_quote_name) is selected, the field, p52_quote_phone_1 will visible with default value defined in std is: 0123456789

This snippet wich you've asked is to remove all faked text fields defined above, and store visible field (p52_quote_phone_1) to p52_quote_phone field 🙂

// Save data to phone field
add_action('rwmb_before_save_post', function($post_id)
{
	// Get person ID to save from "Select a Customer" field
	$person_to_save = intval( $_POST['p52_quote_name'] );
	// Save related field to phone field
	$_POST['p52_quote_phone'] = $_POST['p52_quote_phone_' . $person_to_save];
	// Unset all hidden fields
	foreach ( $_POST as $key => $value )
	{
		if ( strpos( $key, 'p52_quote_phone_' ) )
			unset( $_POST[$key] );
	}
} );

If you still have problem, can you give me your site information to debug?

Hi Maurice,

If you want to display meta value in a template file like single.php, please open that file (not functions.php) and insert the following code at the place you want to show the value:

echo rwmb_meta( 'FIELD_ID', 'type=FIELD_TYPE' );

Don't forget to change FIELD_ID and FIELD_TYPE to your specific field ID and field type.
