Laravel:将视图中的变量传递给控制器
Laravel:将视图中的变量传递给控制器
提问于 2016-07-31 14:24:33
我想将视图中的表单中的两个变量传递给我的控制器，并在那里使用它们.
怎么做？
shop.blade.php：
<div class="mcitem">
<img src="/images/shop/Stein.png" alt="Stein">
<div class="mcunits">
{{ Form::open(array('action' => 'ShopController@add', $itemid, $bprice)) }}
{{ Form::number('units', '0') }}
</div>
<div class="mcbuy">
$itemid = 1;
$bprice = 3;
{{ Form::submit('3,00 Coins', array('name' => 'buybtn')) }}
</div>
<div class="mcsell">
{{ Form::submit('1,00 Coin', array('name' => 'sellbtn', $itemid='1', $sprice=1)) }}
{{ Form::close() }}
</div>
</div>ShopController：
public function add(Request $request){
$this->validate($request, [
'units' => 'required|min:1',
]);
if(Input::Get('buybtn')) {
$this->Buy(); //if Buy Button is pushed
} elseif(Input::Get('sellbtn')) {
$this->Sell(); //if Sell Button is pushed
}
}
public function Buy(){
$username = Auth::user()->name;
$units = Input::Get('units');
if((DB::table('users')->where('name', $username)->value('kontostand')) >= ($bprice*$units)){
$check_entry = DB::table($username)->where('Item', '=', $itemid)->first();
if(is_null($check_entry)){
$hunits = DB::table($username)->where('Item', $itemid)->select('units')->get();
DB::table($username)->where('Item', $itemid)->update([$itemid => $hunits + $units]);
}
else{
DB::table($username)->where('Item', $itemid)->insert(
[$itemid => $units]
);
}
}
else{
echo "Zu wenig Geld auf dem Kontostand!";
}

使用隐藏字段
<div class="mcitem">
<img src="/images/shop/Stein.png" alt="Stein">
{!! Form::open(array('action' => 'ShopController@add')) !!}
<div class="mcunits">
{!! Form::number('units', '0') !!}
</div>
<div class="mcbuy">
{!! Form::hidden('itemid', '1') !!}
{!! Form::hidden('bprice', '3') !!}
{!! Form::submit('3,00 Coins', array('name' => 'buybtn')) !!}
</div>
<div class="mcsell">
{!! Form::submit('1,00 Coin', array('name' => 'sellbtn')) !!}
</div>
{!! Form::close() !!}
</div>控制器
$request->get('itemid);...

<div class="mcunits">
{{ Form::open(array('action' => 'ShopController@add')) }}
{{ Form::number('units', '0') }}
{{ Form::hidden('itemid', 1) }}
{{ Form::hidden('bprice', 3) }}
</div>
<div class="mcbuy">
{{ Form::submit('3,00 Coins', array('name' => 'buybtn')) }}
</div>
$itemid = Input::Get('itemid');
$bprice = Input::Get('bprice');解决以下错误:不支持的操作数类型

ShopController：

$this->validate($request, [
'units' => 'required|min:1',
]);
if(Input::Get('buybtn')) {
$this->Buy(); //if Buy Button is pushed
} elseif(Input::Get('sellbtn')) {
$this->Sell(); //if Sell Button is pushed
}
return view('shop');
}
public function Buy(){
$username = Auth::user()->name;
$units = Input::Get('units');
$itemid = Input::Get('itemid');
$bprice = Input::Get('bprice');
if((DB::table('users')->where('name', $username)->value('kontostand')) >= ($bprice*$units)){
$check_entry = DB::table($username)->where('Item', '=', $itemid)->first();
if(is_null($check_entry)){
//$hunits = DB::table($username)->where('Item', $itemid)->select('units')->first();
//$hunits=(is_null($hunits))?0:$hunits->units;
//DB::table($username)->where('Item', $itemid)->update(['units' => (int)$hunits + $units]);
$hunits = DB::table($username)->where('Item', $itemid)->select('units')->get();
DB::table($username)->where('Item', $itemid)->update(['units' => (int)$hunits + $units]);
