Undefinierte Variable: Lagerkategorie in Laravel

Question

Ich habe versucht, eine Drop-Kategorie-Option aus der Datenbank zu erstellen, so dass der Administrator in der Lage sein kann, die Produktkategorie aus der Select-Option auszuwählen. Aber nachdem ich aus der Datenbank in meinem DashboardController ausgewählt und versucht habe, es in meine Auswahloption in der Form aufzunehmen, erschien ein Fehler auf der Formularseite. Hier

ist der Fehler, der angezeigt wurde, wurde:

Error in 73cd6543c61fa0a342e4d528a9bc24bd5c4c4cbe.php Linie 29: Undefined variable: stockcategory (Ansicht: C: \ wamp \ www \ Pumpe \ core \ resources \ Ansichten \ dashboard \ Lager-create.blade.php)

Was genau mache ich falsch?

Answer 1

Sie verwenden $stockcategory aus Ihrer Sicht, aber Sie müssen es aus dem Controller in dem Verfahren von createStockCategory() ersten senden! Versuchen Sie Folgendes:

public function createStockCategory() 
{ 
    $data['site_title'] = $this->site_title; 
    $data['page_title'] = "Create Stock Category"; 

    return view('dashboard.stockcategory-create', ['stockcategory' => $data]); 
} 

Verweisen Sie auf Docs!

Hoffe das hilft dir !!

Answer 2

Hier in der diese Funktion Pass $data als stockcategory

public function createStockCategory() 
{ 
    $data['site_title'] = $this->site_title; 
    $data['page_title'] = "Create Stock Category"; 

    return view('dashboard.stockcategory-create',['stockcategory' => $data]); 
}
