【中文标题】如何在控制器的 laravel 存储功能中进行保存和打印？【英文标题】：How can I do a save and print in laravel store function in controller? 【发布时间】：2021-10-23 02:09:54 【问题描述】：我有一个执行保存和打印的按钮。我已经可以在store() 函数中保存，但不能打印。当我的意思是打印时，它意味着打开传递数据的打印对话框。
这是我的按钮：
<button type="button" id="save-and-print" name="action_create" value="save_and_print">Save and print</button>
<button type="submit" name="action_create" value="save">Save</button>
ReceiveItemsController.php
public function index()
return view('receive-items.index', ['has_id' => false]);
public function indexWithId($product_id)
return view('receive-items.index', ['product_id' => $product_id, 'has_id' => true]);
public function create()
return view('receive-items.index');
public function store(Request $request)
$allow_print = true;
$product_ids = array_map('intval', $request->product_id);
$qty_per_item = array_map('intval', $request->qty);
ReceiveItems::create([
'created_at' => Carbon::now()->timestamp,
'type' => 'Receiving',
'product_id' => $product_ids,
'no_of_items' => $request->no_of_items,
'qty_per_item' => $qty_per_item,
'total' => $request->total,
'payment' => 'Already paid'
]);
$print_notification = array(
'message' => 'Saved successfully! Printing now...',
'alert-type' => 'success'
);
$success_notification = array(
'message' => 'New products has been added successfully!',
'alert-type' => 'success'
);
$receive_items = $this->printVoucher($product_ids, $qty_per_item);
if ($request->post('action_create') == 'save_and_print')
return view('receive-items.voucher', ['receive_items' => $receive_items,'allow_print' => $allow_print]);
elseif ($request->get('action_create') == 'save')
return redirect()->route('receive-items.index')->with($success_notification);
public function printVoucher($product_ids, $qty_per_item)
$items = [];
foreach($product_ids as $product_item_no => $product_id)
$products = Product::where('id', '=', $product_id);
$voucher_cost = $products->value('cost');
$items[] = array(
'product_item_no' => $product_item_no + 1,
'product_id' => $product_id,
'product_name' => $products->value('name'),
'size' => $products->value('size'),
'qty_addend' => $qty_per_item[$product_item_no],
'voucher_cost' => $voucher_cost,
'ext_cost' => number_format($voucher_cost * $qty_per_item[$product_item_no], 2),
);
return $items;
路线：
Route::post('/print/voucher', function() return view('receive-items.voucher'); );

此代码仅打开带有$received_items 数据的voucher.blade.php，但不会打开打印对话框。可能路线有问题？
非常感谢任何帮助。
【问题讨论】：
【参考方案1】：您似乎正在使用两个刀片文件。所以只需将window.print() 添加到receive-items.voucher.blade.php 中，如下所示
<script>
(function()
window.print()
)();
</script>
这样一旦加载了 dom，打印窗口就会打开。
其他信息
你也可以在下面短你的喜欢
if ($request->post('action_create') == 'save_and_print')
return view('receive-items.voucher', ['receive_items' => $receive_items]);
return redirect()->route('receive-items.index');
更新
由于要求打印在index.blade.php
将额外变量传递给 index.blade 以便您可以使用 print 选项。类似下面的东西
public function index()
$allowPrint = true; // Your logic goes here
return view('receive-items.index', ['receive_items' => $receive_items,'allowPrint' => $allowPrint]);
index.blade.php
@if($allowPrint)
<script>
(function()
window.print()
)();
</script>
@endif
【讨论】：
它现在可以工作了。谢谢@Nipun Tharuksha。我怎样才能让它像它不会打开凭证.blade.php 并且只保留在 index.blade.php 页面上，但仍会打开打印对话框？ 如果有效希望你能接受我的回答谢谢 我已经更新了通过 index.blade.php 打印的答案 谢谢@Nipun Tharuksha。我的意思是我仍然希望它在 store() 函数中保存数据，但仍会显示索引页面。我该怎么做？ 所以它会显示索引并且应该能够打印以上是关于如何在控制器的 laravel 存储功能中进行保存和打印？的主要内容，如果未能解决你的问题，请参考以下文章
