Display element based on 'post'

Hi carassius,

Yes, you're right about using Conditional Logic extension. It's made exactly for this purpose. Please try it and let us know if it works for you.

Thanks.

Hi carassius,

Thanks for using Conditional Logic

As your requested, I've created a snippet with comments so you can see and use in your project. Basically, I use a 'post' field to display all customers and create a phone field which store customer phone and a set of phone fields equal to num of customers which has default value inside, when user post data, the visible phone field will replace default phone field. Have fun 🙂

Can you show me that error?

Ok man, sorry, in my demo, I use 'customer' as post type but in your site, you're using 'p52-contact' as post type so $customer variable return empty, can you please change 'customer' to 'p52-contact'?

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?
