Ich habe einen JSON-Feed von Drittanbietern http://feeds.artlogic.net/artworks/artlogiconline/json/ , den ich zum Importieren von Daten in WordPress als benutzerdefinierten Beitragstyp namens "Grafik" verwenden muss.
Gibt es handliche Plugins, die diese Daten abbilden könnten? Oder gibt es eine praktische API, die das Codieren erleichtert? Ich bin neu in der WordPress-Entwicklung.
Antworten:
Wenn Sie die DIY-Route wollen ...
Der Beitragstyp in diesem Beispiel ist auf "Beitrag" eingestellt, aber Sie können sehen, wo er geändert werden muss. Hier ist ein Arbeitsbeispiel zum Abrufen der Daten (erste Seite in diesem Beispiel), zum Analysieren der Antwort, zum Erstellen einer Klasse für die sauberen (er) Daten, zum Generieren von Posts aus diesen Daten und zum Aktualisieren des Post-Metas für bestimmte Attribute.
Sie möchten anpassen, was den Anruf auslöst, aber dies erzeugt 5 Beiträge, wenn Sie das Front-End erreichen. Sie überprüfen und stellen sicher, dass der Titel und der Slug noch nicht vorhanden sind, bevor sie generiert werden.
Der Inhalt wird nur aus der Artwork_html festgelegt. + Ich habe dort die IMG-URL hinzugefügt. Sie möchten dieses Bild wahrscheinlich mit in Ihre Datenbank abrufen media_sideload_image.
