Problem including ACF Pro in custom plugin

Following this giude: http://www.advancedcustomfields.com/resources/including-acf-in-a-plugin-theme/

I’ve got a plugin that is calling a script. It checks if the class “acf” exists. If it does not exist, it includes ACF Pro from the plugin files. This should let you use ACF Pro as a plugin if you want to keep it updated.

So I’ve got it figured out, with the help of a couple global vars to transmit the paths:

function limelight_include_acf_files( $acf_path, $acf_url, $hide_menu = false ) {
	global $ld_acf_paths;

	$ld_acf_paths = array(
		'path' => $acf_path,
		'url' => $acf_url,
	);

	// 1. customize ACF path
	add_filter('acf/settings/path', 'limelight_acf_settings_path');

	// 2. customize ACF dir
	add_filter('acf/settings/dir', 'limelight_acf_settings_dir');

	// 3. Hide ACF field group menu item
	if ( $hide_menu ) add_filter('acf/settings/show_admin', '__return_false');

	// 4. Include ACF
	include_once( $acf_path . 'acf.php' );

	var_dump($ld_acf_paths);
	var_dump($acf_path . 'acf.php');
	var_dump(acf()->settings);
}

function limelight_acf_settings_path( $path ) {
	global $ld_acf_paths;
	return $ld_acf_paths['path'];
}

function limelight_acf_settings_dir( $dir ) {
	global $ld_acf_paths;
	return $ld_acf_paths['url'];
}

See the var_dumps at the end of “limelight_include_acf_files”? They report the following:

  'path' => string 'G:\Web Development\Wamp Server\www\sports\wp-content\plugins\limelight-ezad-replacement\acf/advanced-custom-fields-pro/' (length=119)
  'url' => string 'http://localhost/sports/wp-content/plugins/limelight-ezad-replacement/acf/advanced-custom-fields-pro/' (length=101)

string 'G:\Web Development\Wamp Server\www\sports\wp-content\plugins\limelight-ezad-replacement\acf/advanced-custom-fields-pro/acf.php' (length=126)

array (size=21)
  'name' => string 'Advanced Custom Fields PRO' (length=26)
  'version' => string '5.3.2.2' (length=7)
  'basename' => string 'limelight-ezad-replacement/acf/advanced-custom-fields-pro/acf.php' (length=65)
  'path' => string 'G:\Web Development\Wamp Server\www\sports\wp-content\plugins\limelight-ezad-replacement\acf\advanced-custom-fields-pro/' (length=119)
  'dir' => string 'http://localhost/sports/wp-content/plugins/limelight-ezad-replacement/acf/advanced-custom-fields-pro/' (length=101)
  'show_admin' => boolean true
......
  'pro' => boolean true
}

This all looks good. The directory and URLs are correct (barring the backslash/forward slash mixup, but PHP doesn’t mind that). The ACF function is pulling in the settings properly, as we can see at the end.

All is well so far, but I get a ton of errors on the admin.

( ! ) Notice: Trying to get property of non-object in G:\Web Development\Wamp Server\www\sports\wp-content\plugins\limelight-ezad-replacement\acf\advanced-custom-fields-pro\api\api-helpers.php on line 19

Line 19: $settings = acf()->settings;

( ! ) Warning: Attempt to modify property of non-object in G:\Web Development\Wamp Server\www\sports\wp-content\plugins\limelight-ezad-replacement\acf\advanced-custom-fields-pro\api\api-helpers.php on line 72

Line 72: acf()->settings[ $name ] = $value;

It’s as if acf() isn’t available anymore.

Any ideas?

Here is a copy of the plugin so far. Which is almost nothing. I removed ACF Pro itself from the “acf” folder so you’ll need to put that in t here yourself.

No, unfortunately. I’ve tried a few things to get it to work but in the end I had given up.

Hi

Ive succeeded to solve this issue at least in my end

Heres the code:

// 1. customize ACF path
add_filter('acf/settings/path', 'my_acf_settings_path');

function my_acf_settings_path( $path ) {

// update path
$path = dirname( __FILE__ ) .  '/libs/acf/';

// return
return $path;

}

// 2. customize ACF dir
add_filter('acf/settings/dir', 'my_acf_settings_dir');

function my_acf_settings_dir( $dir ) {

// update path
$dir = plugin_dir_url( __FILE__ ) . 'libs/acf/';

// return
return $dir;

}

// 3. Hide ACF field group menu item
//add_filter('acf/settings/show_admin', '__return_false');

// 4. Include ACF
include_once( 'libs/acf/acf.php' );
