Wie wird die Warenkorbmenge in CodeIgniter aktualisiert?

Question

Ich möchte die Menge eines Einkaufswagens aktualisieren. Ich habe es viel google aber konnte es nicht tun.

Maximale Seiten zeigen, was ich nicht will. Genaue Lösung bekomme ich nicht. Hoffentlich komme ich hierher. Bitte hilf mir, es zu tun. Hier ist meine Ansicht Seite.

**<table class="table table-hover table-bordered table-striped snipcart-details "> <thead> 
       <tr> 
        <th style="color:#FF0033; font-weight:bolder; text-align:center;" >Delete Cart</th> 
        <th style="color:#FF0033; font-weight:bolder; text-align:center;" >Product Name</th> 
        <th style="color:#FF0033; font-weight:bolder; text-align:center;" >Image</th>

       <tbody>     
       <?php foreach ($this->cart->contents() as $items) { ?> 
       <tr>

    $this->cart->insert($data2);   
    redirect('cart'); 
} 

public function deleteCartItem() { 
    $row_id    = $this->input->post('row_id'); 
    $data = array(
     'rowid' => $row_id, 
     'qty'  => 0 
    ); 
    $this->cart->update($data); 
} 

Bitte helfen Sie mir, die Warenkorbmenge zu aktualisieren. Danke im Voraus.

Answer 1

Zum Warenkorb Artikel aktualisieren:

function updateCartItem(){ 
     $data=array(
      'rowid'=>$this->input->post('rowid',TRUE), 
      'qty'=> $this->input->post('quantity',TRUE) 
      ); 

       if ($this->cart->update($data)) { 
       echo "Success";   
       }else{ 
        echo "Faliure"; 
       } 

} 

den Artikel aus dem Warenkorb zu entfernen:

function deleteCartItem(){ 
$row_id = $this->input->post('row_id',TRUE); 
    if ($rowid) { 
      return $this->cart->remove($rowid); 
     } 
}
