Shortcode-Attribute
‚category_in‘ – Use this attribute if you only want one or several categories to be available for subscription. Value to be entered is the name of the category. Note that only level 0 (no parent) values can be entered.
‚category_id_in‘ – The difference to above is to use the category ID instead of category name.
‚category_not_in‘ – Use this attribute if you want to exclude categories to be available for subscription. Value to be entered is the name of any category.
‚category_id_not_in‘ – The difference to above is to use the category ID instead of category name.
For the above attributes you can use a comma sign to separate multiple categories, like [stc-subscribe category_in=“news, article“].
‚hide_unsubscribe‘ – hide_unsubscribe=“true“ disables the unsubscribe feature but only if the shortcode attribute is also enabled at the admin setting
‚treeview_folded‘ – treeview_folded=“false“ unfolds the category / taxonomy tree view by default
‚treeview_enabled‘ – treeview_enabled=“false“ displays the categories / taxonomies as one list ignoring hierarchy. Please note that only the selected categories are in or out
‚keyword_search‘ – keyword_search=“on“ enables the search for keywords in new or updated selected post types. Default is keyword_search=“off“
’subscriber_notification‘ – subscriber_notification=“true“ enables email notification on an individual per subscriber basis. Default is subscriber_notification=“false“
‚mobile_phone‘ – mobile_phone=“on“ enables the SMS Notification function. This will send SMS Notifications just like the the E-mail notifications for new or updated posts.

Optional, aber empfohlen
Da WordPress Cron davon abhängt, dass du Besuche auf deiner Website hast, solltest du einen Cronjob auf deinem Server einrichten, der in regelmäßigen Abständen auf http://yourdomain.com/wp-cron.php zugreift, um sicherzustellen, dass WP Cron wie erwartet läuft. In der aktuellen Version von Subscribe to Category läuft der WP Cron einmal stündlich, das könnte eine Option sein, die in zukünftigen Versionen geändert werden kann.
Daher könnte ein vorgeschlagenes Intervall für deinen Server Cron einmal alle 5 Minuten sein.
FAQ
-
Kann STC zusätzlichen HTML-Inhalt in die Benachrichtigungs-E-Mail einfügen
-
Ja, indem man die verfügbaren Hooks benutzt, um (an 6 Stellen) HTML-Inhalte in die Benachrichtigungs-E-Mail einzufügen. Aber es erfordert Programmierkenntnisse, um sich an STC anzuschließen. Seit Version 2.4.9 ist dies auf eine viel ausgeklügeltere Weise möglich. Siehe für die Stellen, an denen du HTML-Screenshot-10.jpg einfügen kannst
Für einen Neuanfang ist der einfachste Weg, alle HTML-E-Mail-Templates (veröffentlicht und verworfen) zu löschen. Dann wird STC automatisch ein bearbeitbares STC-Demo-E-Mail-Template wie in Screenshot-11 erstellen. Vergiss nicht, diese Vorlage unter STC Subscribe -> Einstellungen zu aktivieren.
Or follow the 3 steps below.
step 1: STC Subscribe->Notifications->Add New notification to create a new e-mail notification template.
Step 2: Edit the post best in block-editor using a single html block. All styling must be within each HTML element. Remember not all email providers handle all HTML styles. Use the placeholders like {{post_title}},{{post_content}},{{justify}} and {{unsubscribe}}. For more details look in Chapter 5 of STC’s User Manual
step 3: Enable the required post template in the STC admin settings. -
Kann das STC-Widget mit Attributen umgehen
-
Ja, ab Version 2.4.16 hat der Einstellungsbereich des Widgets ein Feld zum Hinzufügen von Attributen. Das Format ist das gleiche wie in der Shortcode.
-
Kann STC mit individuellen Inhaltstypen umgehen
-
Ja, ab Version 2.4.1 ist es möglich, STC mit individuellen öffentlichen Inhaltstypen zu verlinken. Du kannst die indiuviduelle Inhaltstypen auf der STC-Admin-Einstellungsseite auswählen
-
Kann STC individuelle Taxonomien verarbeiten
-
Ja, ab Version 2.3.1 ist es möglich, STC mit individuellen Taxonomien zu verknüpfen. Du kannst diese innerhalb von STC auf der STC-Admin-Einstellungsseite aktivieren.
-
Warum kann ich nur Kategorien/Taxonomien der Stufe 0 für die „Kategorie in Filtern“ haben
-
Das liegt daran, dass, wenn du eine untergeordnete Kategorie zum Filtern auswählst, die Baumansicht nicht mitten im Nirgendwo beginnen kann. Wenn das Attribut ‚treeview_enabled=“false“ aktiv ist, ist es jedoch möglich, eine untergeordnete ohne übergeordnete Kategorie auszuwählen, da diese als eine einzige Kategorie/Taxonomie aufgelistet sind.
-
Wie kann ich die Kategorien und Taxonomien anstelle der Baumansicht auflisten lassen
-
Du kannst eine Kategorie/Taxonomie als Liste haben, indem du das Shortcode-Attribut treeview_enabled=“false“ hinzufügst. Bitte beachte, dass bei aktiviertem Attribut die Kategorie/Taxonomie „in Filtern“ die Hierarchie ignoriert, was dazu führt, dass die Liste genau der Liste entspricht, die im Attribut „in Filter“ angegeben ist.
-
Wie sollte das Format für den Import von Abonnenten aussehen?
-
STC kann nur mit Tab-getrennten Dateien umgehen, da die Kategorien mit Kommas voneinander getrennt sind.↵
(Unter anderem) Excel gibt dir die Möglichkeit, das Arbeitsblatt als Tab-getrennte TXT-Datei zu exportieren.
