InvalidArgumentException 空号无效 laravel omnipay paypal 集成

问题描述

使用 omnipay 将 paypal 集成到我的 Web 应用程序，我遇到此错误 invalidargumentexception Empty number is invalid 当我尝试将 project_id 保存在付款表中时出现错误。 下面是我的代码。对于 paypal 正在使用的两个函数。请任何人帮助我一直坚持使用此代码一周，我想将 project_id 保存在付款表中，以便我可以使用它来创建之间的关系两个表既是付款表又是项目表 这是我的 PaymentController 当我在 payment_success 函数中添加这部分 'items' => array( array( 'project_id' => $project->project_id ),), 时，出现上述错误。

    public function charge(Request $request,$id)
    {
        $project = Project::findOrFail($request->id);
        if($request->input('submit'))
        {
            //$project = new Project();
            $project = Project::findOrFail($request->id);
            $project->update(['user_name' => (Auth::user()->name)]);
            $project->update(['invoice_id' => (null)]);
            $project->update(['payment_status' => ('initialised')]);
            $project->save();
