How do i locate wordpress plugin directory?

Question

I am trying to add a function from plugin 1(wp job manager) to plugin 2(woocommerce).

I have decided to do this by including the php file from plugin 1, however I am unable to locate the file directory. I have used:

 include( plugin_dir_path( __FILE__ ) . 'wp-job-manager/includes/class-wp-job-manager-applications.php');

but it returns the following error:

Warning: include(/home/content/p3pnexwpnas05_data02/78/2394078/html/wp-content/themes/listify-child/wp-job-manager/includes/class-wp-job-manager-applications.php): failed to open stream: No such file or directory in /home/content/p3pnexwpnas05_data02/78/2394078/html/wp-content/themes/listify-child/functions.php on line 77

Please advise me as I've been stuck on this issue for really long... Thanks!!!

Answer 1

Wordpress setups have a constant ABSPATH defined (look at the bottom lines of wp_config.php) which points to the full and absolute path of the Wordpress setup, so in your case echo ABSPATH; would return /home/content/p3pnexwpnas05_data02/78/2394078/html/.

For most installations, appending wp-content/plugins/ to that string would point you to your plugins directory.

However, in a Wordpress configuration one can also customize the wp-content and or plugins directory to their own preference, so building plugins on ABSPATH.'wp-content/plugins/ is not recommended. Unfortunately Wordpress simply doesn't have a get_absolute_pluginspath() function or something available. A trick would be to fetch the plugins-URL, and remove the site-URL from it, so the remaining data is wp-content/plugins/ (or whatever the user has made of it). In code:

$plugins_directory = ABSPATH.str_replace(site_url()."/","",plugins_url())."/";

Which in your case would return: /home/content/p3pnexwpnas05_data02/78/2394078/html/wp-content/plugins/
