Modal Confirm Box in Codeigniter PHP

Ich habe eine Ansicht in meinem Projekt (PHP codeigniter), wo der Benutzer einen bestimmten Datensatz aus der Tabelle der angezeigten Daten bestätigen oder entfernen kann. Wenn der Benutzer entscheidet, einen Datensatz zu bestätigen, erscheint ein modales Popup-Fenster, das die Bestätigung bestätigt. Durch Klicken auf die Schaltfläche Confirm in diesem Modal wird eine Controller-Methode aufgerufen, um die DB-Tabelle über einen entsprechenden Modellmethodenaufruf entsprechend zu aktualisieren. Dasselbe gilt für die Remove-Funktionalität in der Ansicht. Ich habe alle entsprechenden Methoden implementiert und aufgerufen, aber das scheint keine Auswirkungen zu haben.Modal Confirm Box in Codeigniter PHP
