语法:: parameterize()必须为数组类型 [英] Grammar::parameterize() must be of the type array

问题描述

我收到此错误

传递给Illuminate \ Database \ Grammar :: parameterize()的参数1必须为数组类型，给出字符串，

Argument 1 passed to Illuminate\Database\Grammar::parameterize() must be of the type array, string given,

当我尝试使用选择表单在视图中添加array[]时.但是，当我删除它时，我没有得到任何错误.我只是想在我的选择列表中输入多个值.我需要为此使用foreach吗?

when I tried add array[] in my View using select form. But when I removed it I didn't get any error. I'm just trying to input a multiple value in my select list. Do I need to use foreach for this?

查看

<div class = "form-group {{ $errors->has('approver') ? ' has-error' : '' }}">

    <label for = "approver" class = "control-label">Approver:</label>

    <select name = "approver[]" multiple class = "form-control select2-multi">

        @foreach ($approver as $list)
            <option value = "{{ $list->id }}">{{ $list->username }}</option>
        @endforeach

    </select>

    @if ($errors->has('approver'))
        <span class = "help-block">{{ $errors->first('approver') }}</span>
    @endif

</div>

控制器

public function getDocuments()
{
   $approver = DB::table('users')->where('id', '!=', Auth::id())->get();

   return view ('document.create')->with('approver', $approver);
}

public function postDocuments(Request $request)
{

    $this->validate($request,
    [
        'title' => 'required|regex:/(^[A-Za-z0-9 ]+$)+/|max:255',
        'content' => 'required',
        'category' => 'required',
        'recipient' => 'required',
        'approver' => 'required',
    ]);     


    $document = new Document();
    $approve = new Approve();
    $user = Auth::user();
                                //Request in the form
    $document->title = $request->title;
    $document->content = $request->content;
    $document->category_id = $request->category;
    $approve->approver_id = $request->approver;

    $approve->save();

    $document->save();

    $document->sentToApprovers()->sync([$approve->id],false);

}

更新

我死掉并转储了$approver变量，并给出了一个值数组.

I die and dump the $approver variable and gives a array of value.

也死掉并丢弃$request正如您在此处看到的那样，我在选择列表中输入了 4 和 5 的ID.

Also die and dump the $request As you can see here I input the id of 4 and 5 in my select list.

推荐答案

好吧，您的问题是您试图将数组另存为单数，而需要在其上遍历批准者.

Ok, your issue is that you're trying to save an array as a singular value where you need to iterate over the approvers instead.

将控制器逻辑更改为此:

Change your controller logic around to this:

foreach ($request->approver as $approver) {
    $approve              = new Approve();
    $approve->approver_id = $approver;
    $approve->save();

    $document->sentToApprovers()->sync([$approve->id],false);
}
