Embedding Ultimate Fields into Custom Plugin

Hi Dragon Heart,

this is not the correct way to do it, because in the plugin, I am not checking if the constant is already defined or not, which means that you will be getting a PHP notice. If you enable the WP_DEBUG constant, which you should definitely do, you will see it.

Checking the code in https://plugins.trac.wordpress.org/browser/ultimate-fields/trunk/common/startup.php , the plugin should automatically work even when within another plugin, but right now I don’t have the time to check what the bug is.

However, as you see in the uf_start() function, there is a filter called “uf_startup_vars”. You can use it in the following way, assuming that you apply the filter in your root plugin file:

<?php
add_filter( 'uf_startup_vars', 'my_plugin_uf_startup_vars' );
function my_plugin_uf_startup_vars( $vars ) {
	$vars[ 'url' ] = plugins_url( 'includes/ultimate-fields/', __FILE__ );
	return $vars;
}

For the tabs: Note taken. I had this fixed somewhere, but I’ve obviously broken it again 🙂

And lastly, the answer to the PS:
The plugin is under constant development, but not in the version you see here. I am nearly ready with version 2 (at least functionality-wise, there could be a few bugs) and am working on the website and documentation for it.

If you really like the plugin and are determined to use it within yours, I strongly suggest that you try the beta, which you can find at https://github.com/RadoslavGeorgiev/ultimate-fields . As this would pretty much be beta testing, I would be glad to help you with any issues/bugs, arising during your work, as fast as I can.

Best regards,
Rado

Hi again,

currently this cannot be achieved neither through Ultimate Fields 1, nor 2. At least not without, as you said, hacking the plugin, which of course is not recommended.

To achieve this you would need:

1. A custom field type, although technically you’d be able to achieve it through hacking of the select field
2. Some additional JavaScript because currently fields live within an enclosure, which does not allow them to know what other fields exist nor their values.

However, you got me interested, so I will check if I can figure out something sleek within the next day and share it with you, as I have the feeling that this functionality will be requested for many situations.

In this particular case, I feel the need for some core functionality that’s why I am giving it a try. Otherwise you would have to create the field on your own, which will include some code and if the sole purpose of including UF within your plugin is to have those two fields, it would simply be too much overhead.

I am not aware if you need this for a post type or as an options page, so I cannot immediately point you in a particular direction, but if you share some more details, I would be glad to.

Bye for now,
Rado
