Title: Custom Hooks Last modified: August 30, 2016 --- # Custom Hooks * Resolved [eupalinos](https://wordpress.org/support/users/eupalinos/) * (@eupalinos) * [10 years, 8 months ago](https://wordpress.org/support/topic/custom-hooks-1/) * Hi, Eventualo. How’re you doing? I hope everything is fine. * At the moment, I’m sending out two attachments for every newsletter subscriber using the function snippet below, inside the mu-plugin folder. * I was wondering how I could tweak it to send out either two attachments in Italian or two attachments in English, depending on the selection the subscriber makes for the newsletter language (Italian / English.) * If you could help me yourself, or direct me to some site that has some information. * PS.: When the email field is empty, your plugin gives the message: “The e-email address is not correct”, but should be: “The e-mail address is not correct” e- mail, not e-email. * Thanks! * Marco. * ————————————– custom hooks function snippet * function custom_easymail_subscriber_activated ( $email ) { // uncomment next lines to send a welcome message to just-activated subscribers add_filter(‘wp_mail_content_type’, create_function(”, ‘return “text/html”; ‘)); $attachments = array(); $subscriber = alo_em_get_subscriber( $email ); $subject = “Welcome to the Newsletter!”; $ body = file_get_contents(WP_CONTENT_DIR . ‘/uploads/email_text.php’); array_push( $attachments, WP_CONTENT_DIR . ‘/profile-pics/attachment1.epub’ ); array_push( $attachments, WP_CONTENT_DIR . ‘/profile-pics/attachment2.mobi’ ); wp_mail( $ email, $subject, $body, false, $attachments); } —————————————————— * [https://wordpress.org/plugins/alo-easymail/](https://wordpress.org/plugins/alo-easymail/) Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [eventualo](https://wordpress.org/support/users/eventualo/) * (@eventualo) * [10 years, 8 months ago](https://wordpress.org/support/topic/custom-hooks-1/#post-6486470) * You can get the 2-chars-language-code using `alo_em_get_language` function, then you can attach the right files depending on the language. A quick sample: * ``` $lang = alo_em_get_language(); if ( $lang == 'en' ) { // The English attachs array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment1_EN.epub'; // ... } else if ( $lang == 'it' ) { // The Italian attachs array_push($attachments, WP_CONTENT_DIR .

Or an Italian-based user may want to receive the English Newsletter. * Moreover, I got a lot of subscribers with an empty Language tab in the Alo Easy Mail Subscribers panel. * That’s why attachments based on subscription list-IDs would be more to the point IMHO, because subscribers would choose the list, hence what they’d like to be sent. Just think of a subscription policy based on book genres (romance, sci- fi, thriller, etc.) that gives away samples on subscription. In this case, language would be irrelevant. * Can’t it be done using list IDs? * Thank you for yor time. * Again, don’t forget to change the “e-email” to “e-mail” in the messages printed out by your plugin. * Marco. * Thread Starter [eupalinos](https://wordpress.org/support/users/eupalinos/) * (@eupalinos) * [10 years, 8 months ago](https://wordpress.org/support/topic/custom-hooks-1/#post-6486478) * Hello. * I tried this, but nothing is sent after the activation, ergo that’s not the right way to retrieve the $list_id parameter: * ``` $attachments = array(); $subscriber = alo_em_get_subscriber( $email ); if ( $list_id == 2 ) { // The English attachs $subject = "Welcome to the Newsletter!"; $body = file_get_contents(WP_CONTENT_DIR . '/uploads/eng.php'); array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment1_eng.epub' ); array_push($attachments, WP_CONTENT_DIR .

About the subscriber mailing list you can use `alo_em_get_user_mailinglists` that returns an array of list IDs, e.g.: * ``` $attachments = array(); $subscriber = alo_em_get_subscriber( $email ); $lists = alo_em_get_user_mailinglists( $subscriber->ID ); foreach ( $lists as $list ) { if ( $list == 1 ) { // the list ID array_push($attachments, WP_CONTENT_DIR . '/profile-pics//attachment_list_1.mobi' ); } /* else if list == 2 .... etc */ } ``` * About my first snippet, it’s wrong about subscriber language. You can get it with `alo_em_get_subscriber`, e.g.: * ``` $subscriber = alo_em_get_subscriber( $email ); if ( $subscriber->lang == 'it' ) { // ... } // else ... ``` * Thread Starter [eupalinos](https://wordpress.org/support/users/eupalinos/) * (@eupalinos) * [10 years, 8 months ago](https://wordpress.org/support/topic/custom-hooks-1/#post-6486486) * Hey, that works! * Also: * ``` // if two checkboxes are pressed: elseif ( $list == 6 && $list == 2 ) {...} ``` * One last question, I swear — what if no checkbox is pressed? I tried with: * $list == 0 * or * $list == 1 * or * $list == NULL * but none worked. * In both cases, the final ELSE condition in the FOREACH loop doesn’t send anything. * M. * Plugin Author [eventualo](https://wordpress.org/support/users/eventualo/) * (@eventualo) * [10 years, 8 months ago](https://wordpress.org/support/topic/custom-hooks-1/#post-6486487) * Remind that `$lists` can be: an array of list IDs and the `$list` inside foreach is the ID of each list, or false if subscriber didn’t check any lists. Before the foreach you should check if subscriber checked at least a list, so the updated code can be: * ``` $attachments = array(); $subscriber = alo_em_get_subscriber( $email ); $lists = alo_em_get_user_mailinglists( $subscriber->ID ); if ( is_array( $lists ) ) { foreach ( $lists as $list ) { if ( $list == 1 ) { // the list ID array_push($attachments, WP_CONTENT_DIR . '/profile-pics//attachment_list_1.mobi' ); } /* else if list == 2 .... etc */ } } else { // No lists selected by subscriber } ``` * Thread Starter [eupalinos](https://wordpress.org/support/users/eupalinos/) * (@eupalinos) * [10 years, 8 months ago](https://wordpress.org/support/topic/custom-hooks-1/#post-6486488) * Thanks a lot, Alessandro! * Please, mark the thread as solved. * Marco. * Thread Starter [eupalinos](https://wordpress.org/support/users/eupalinos/) * (@eupalinos) * [10 years, 8 months ago](https://wordpress.org/support/topic/custom-hooks-1/#post-6486492) * For completion, I’m adding another way to do it, using the in_array php function: * ``` $attachments = array(); $subscriber = alo_em_get_subscriber( $email ); $lists = alo_em_get_user_mailinglists( $subscriber->ID ); // I have two subscription lists: ID 2 (English Newsletter) and ID 6 (Italian Newsletter) // Each list has its own separate check button in the submission form. // Checking if no selection is made if ( is_array( $lists ) ) { // Checking array $lists whether double selection is made: if(in_array('2',$lists) && in_array('6',$lists)){ $subject = "Welcome to the Newsletter!"; $body = file_get_contents(WP_CONTENT_DIR . '/uploads/html_eng.php'); array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment1_eng.epub' ); array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment2_eng.mobi' ); array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment1_ita.epub' ); array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment2_ita.mobi' ); } // Checking if only the English Newsletter is selected (ID 2) elseif(in_array('2',$lists)){ $subject = "Welcome to the Newsletter!"; $body = file_get_contents(WP_CONTENT_DIR . '/uploads/html_eng.php'); array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment1_eng.epub' ); array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment2_eng.mobi' ); } // Checking if only the Italian Newsletter is selected (ID 6) elseif(in_array('6',$lists)){ $subject = "Benvenuto alla Newsletter!"; $body = file_get_contents(WP_CONTENT_DIR . '/uploads/html_ita.php'); array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment1_ita.epub' ); array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment2_ita.mobi' ); } // If none of the above: else { $subject = "Welcome to the Newsletter!"; $body = file_get_contents(WP_CONTENT_DIR . '/uploads/html_eng.php'); array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment1_eng.epub' ); array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment2_eng.mobi' ); } } // Closing ELSE of the "no selection is made" check above. else { $subject = "Welcome to the Newsletter!"; $body = file_get_contents(WP_CONTENT_DIR . '/uploads/html_eng.php'); array_push($attachments, WP_CONTENT_DIR . '/profile-pics/attachment1_eng.epub' ); array_push($attachments, WP_CONTENT_DIR .
