Wie man einen bool Wert in prestashop ändert 1.6 back end by icon klicken

Question

Ich möchte meinen Druckstatus ändern, ich kann das Symbol platzieren, um den Status zu ändern, aber die Änderung tritt nicht auf, wenn ich auf das Druckstatus-Symbol klicke Im Bild habe ich den Callback als changePrintStatus

der Code erreicht initProcess(), wenn das Change-Status-Symbol geklickt wird, Aber danach was genau muss passieren ?? Oder muss ich eine andere Funktion/override-Funktion aufrufen ? (Ich habe das gleiche wie in Kundenliste machen wollen, wo wir aktiv Status der Kunden ändern, in ähnlicher Weise möchte ich hier für meine benutzerdefinierten Modul tun)

Answer 1

ich die Prozessfunktion fehlt:

** Beachten Sie aber, dass $ this-> action = 'change_print_val'; und Name f der Prozess muss in meinem Fall ähnlich sein processChangePrintVal

Also, wenn Aktion ist $ this-> action = 'change_printStatus_val'; dann müssen Prozessname processChangePrintStatusVal **

sein I Below-Funktion hinzugefügt

/** 
* Toggle the Eticket Print Status flag- Here the update action occurs 
*/ 
public function processChangePrintVal() 
{ 
$eticket = new Eticket($this->id_object); 
if (!Validate::isLoadedObject($eticket)) { 
$this->errors[] = Tools::displayError('An error occurred while updating Eticket Print Status information.'); 
} 
$eticket->print_status = $eticket->print_status ? 0 : 1; 
if (!$eticket->update()) { 
$this->errors[] = Tools::displayError('An error occurred while Eticket Print Status customer information.'); 
} 
Tools::redirectAdmin(self::$currentIndex.'&token='.$this->token); 
}
