问题描述
我正在创建一个网站.在这个网站上,我创建了一个注册表.因此,我创建了一个名为saveInvoice的函数以将所有数据插入数据库.之后,我创建了另一个名为sendemail的函数.我已经从saveInvoice传递了2个参数到sendmail函数,像这样-
I am creating a web site. In this web site, I have created a registration form. So , I have created a function called saveInvoice to insert all the data into the database. After that I created another function called sendemail. I have passed 2 arguments to sendmail function from saveInvoice like this -
$this->sendemail($request, $total);
但是,当我单击提交"按钮时,它给了我这个错误-
But , when I click Submit button, it gives me this error -
Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_RECOVERABLE_ERROR)
Type error: Too few arguments to function App\Http\Controllers\InvoicesController::sendemail(), 1 passed and exactly 2 expected
如何解决此问题?
这是saveInvoice函数.
Here is saveInvoice function.
public function saveInvoice(Request $request)
{
if (Auth::user()) {
$settings = Setting::find(1);
$invoiceNo = $settings->invoiceprefix . '' . str_pad($settings->invoiceno, $settings->invoicepadding, 0, STR_PAD_LEFT);
$Qty = $request->input('Qty');
$price = $request->input('price');
$total = $Qty * $price;
$invoice = new Invoice();
$invoice->invoicereference = $invoiceNo;
$invoice->firstname = $request->fname;
$invoice->save();
if ($invoice == null) {
return redirect()->back()->with('msg', 'invalid request');
} else {
$this->sendemail($request, $total);
return redirect()->route('invoice.preview', $invoiceNo);
}
}
}
这是sendemail功能.
Here is sendemail function.
public function sendemail(Request $request, $total)
{
$invoiceNo = $request->input('invoiceNo');
$fname = $request->input('fname');
$sendemail = $request->input('email');
$data = [];
$data['invoiceNo'] = $invoiceNo;
$data['fname'] = $fname;
$data['total'] = $total;
$data['sendemail'] = $sendemail;
Mail::send(['html' => 'mail'], $data, function ($message) use ($data) {
$message->to($data["sendemail"], 'TicketBooker')->subject
('CheapEfares Order Invoice');
$message->from('[email protected]', 'CheapEfares');
});
return Redirect::back();
}
路线.
Route::Post('invoice/addinvoice', [
'uses' => 'InvoicesController@saveInvoice',
'as' => 'invoice.save'
]);
Route::get('sendemail','InvoicesController@sendemail')->name('sendemail');
推荐答案
从路由调用函数sendemail()
时.它仅向其传递一个参数,例如:
As you are calling function sendemail()
from route. It's passing only one parameter to it like:
sendemail($request);
也$total
变量根本不在功能sendemail()
中使用.因此,将其删除或使其变为可选,例如:
Also $total
variable not being used in function sendemail()
at all. So remove it or make it optional like:
public function sendemail(Request $request, $total = "") {
$invoiceNo = $request->input('invoiceNo');
$fname = $request->input('fname');
$sendemail = $request->input('email');
$data = [];
$data['invoiceNo'] = $invoiceNo;
$data['fname'] = $fname;
$data['total'] = empty($total) ? 0 : $total;
$data['sendemail'] = $sendemail;
Mail::send(['html' => 'mail'], $data, function ($message) use ($data) {
$message->to($data["sendemail"], 'TicketBooker')->subject
('CheapEfares Order Invoice');
$message->from('[email protected]', 'CheapEfares');
});
return Redirect::back();
}
您还可以通过路径传递总变量.
Also you can pass total variable through routes as well.
Route::get('sendemail/{total}','InvoicesController@sendemail')->name('sendemail');
