我想我只是在查看它，但我无法将变量显示在我的 View 中。
在同一个 Controller 中，我调用一个函数，从那里我返回一个包含变量(也是数组)的数组。在我最初启动的函数中，我将变量发送到 View 。
但是，在 View 中我收到一条错误，指出变量未定义。
我需要的信息在数组 $items 和数组 $trans 中。这些需要进入功能确认并最终出现在确认 View 中。
这两个函数(我尝试删除大多数与问题无关的代码):
public function confirmation($order_id){
$order = Orders::findOrFail($order_id);
if(isset($order->transaction_id)){
$data = [];
$data['order_id'] = $order->order_reference;
$data['trans'] = $order->dat['tr'];
$data['items'] = $order->dat['it'];
return view('confirmation', $data);
}else{
//Nothing relevant
}
}
public function sendpicqer($order_id){
$order = Orders::with(['orderDetails', 'orderAddress', 'customer'])->where('order_id', $order_id)->first();
$order_details = OrderDetails::where('order_id', $order_id)->get();
$error = $order_id;
$result = $this->picqer->addCustomer($customer);
if(!isset($result['data'])){
$error = $result;
if(is_array($result)){
$error = json_encode($result);
}
return redirect()->route('cancel');
}
$orderData = [
'idcustomer' => $result['data']['idcustomer']
];
$orderData['products'] = [];
$items = [];
foreach($order_details as $od){
$pid = $od->product_id;
switch ($pid) {
case 1:
$pid = 2399983;
break;
case 2:
$pid = 2399990;
break;
}
$orderData['products'][] = [
'idproduct' => $pid,
'amount' => $od->quantity
];
$items[] = [
'sku' => $pid,
'name' => $od->product_id->product_name,
'price' => $od->product_id->product_price,
'quantity' => $od->quantity
];
}
$result = $this->picqer->addOrder($orderData);
if(isset($result['data'])){
//Succeeded!
$idorder = $result['data']['idorder'];
$orderid = $result['data']['orderid'];
$trans = array('id' => $orderid, 'affiliation' => 'Matt Sleeps', 'revenue' => $order->total_price);
$dat = [];
$dat['tr'] = $trans;
$dat['it'] = $items;
return $dat;
$result2 = $this->picqer->sendRequest('/orders/'.$idorder.'/process', null, 'POST');
if(!isset($result2['data'])){
$error = $result2;
if(is_array($result2)){
$error = json_encode($result2);
}
return redirect()->route('cancel');
}
}else{
$error = $result;
if(is_array($result)){
$error = json_encode($result);
}
return redirect()->route('cancel');
}
//Order is successfully confirmed and send to Picqer!
$error = '(Both to the customer and with Picqer)';
}
这是我需要访问变量的 View 部分:
<?php
var_dump($order_id);
var_dump($trans);
var_dump($items);
// Function to return the JavaScript representation of a TransactionData object.
function getTransactionJs(&$trans) {
return <<<HTML
ga('ecommerce:addTransaction', {
'id': '{$trans['id']}',
'affiliation': '{$trans['affiliation']}',
'revenue': '{$trans['revenue']}'
});
HTML;
}
// Function to return the JavaScript representation of an ItemData object.
function getItemJs(&$transId, &$item) {
return <<<HTML
ga('ecommerce:addItem', {
'id': '$transId',
'name': '{$item['name']}',
'sku' : '{$item['sku']}',
'price': '{$item['price']}',
'quantity': '{$item['quantity']}'
});
HTML;
}
?>
<script>
<?php
echo getTransactionJs($trans);
foreach ($items as &$item) {
echo getItemJs($trans['id'], $item);
}
?>
ga('ecommerce:send');
</script>
最佳答案
您必须将变量发送到 View 。您可以将代码更改为如下所示:
//Return the view via confirmation function.
public function sendpicqer($order_id){
...
return $this->confirmation($order_id, $items, $trans);
}
public function confirmation($order_id, $items, $trans){
$order = Orders::findOrFail($order_id);
if(isset($order->transaction_id)){
$data = [];
$data['order_id'] = $order->order_reference;
$data['trans'] = $trans;
$data['items'] = $items;
//Send the variables to the view
return view('confirmation', $data);
}else{
return redirect()->route('cancel');
}
}
希望这有帮助...
