Hey there!

i am using the code below to change my Blogtitle by a custom field in the option tree via the functions php:

	$value = get_field('blogtitle', 'option');		
	if ($value) {
		update_option('blogname', $value);
	} else {
    	update_option( 'blogname', '' );	
	}

if i update or deactivate the acf plugin i get an error for the variable $value. How can i check if acf is existing/activated?

Thank you in avance!

The following code checks if the ACF Pro or ACF plugins are not activated.

/* Checks to see if "is_plugin_active" function exists and if not load the php file that includes that function */
if ( ! function_exists( 'is_plugin_active' ) ) {
	include_once( ABSPATH . 'wp-admin/includes/plugin.php' ); 
}

/* Checks to see if the acf pro plugin is not activated  */
if ( !is_plugin_active('advanced-custom-fields-pro/acf.php') )  {
 /* Do something when not active */
}

/* Checks to see if the acf plugin is not activated  */
if ( !is_plugin_active('advanced-custom-fields/acf.php') )  {
  /* Do something when not active */
}

Thank you!

I just missed to write

if ( ! function_exists( 'is_plugin_active' ) ) {
	include_once( ABSPATH . 'wp-admin/includes/plugin.php' ); 
}

while i was calling:

if ( is_plugin_active('advanced-custom-fields-pro/acf.php') )  {
    /* My code goes here */
}

in my previous attempts.

Solved, Thank you very much!
