拉拉维尔的表格请求

Question

1.如何处理拉拉维尔表单请求中的问号？

2.我应该为每个输入标签设置默认值吗？

债券控制器.php

public function store(Request $request)

Answer 1

可以为空，但是您的 字段中的字段不能为空。因此，您可以使用验证程序来检查字段。或者在此字段中设置默认值。request('investment')investmentbonds使用验证器：尝试像这样使用验证器：public function store(Request $request)&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; $this->validate($request, [&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 'investment' => 'required',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ...&nbsp; &nbsp; &nbsp; ]);&nbsp; &nbsp; &nbsp; $bond = Bond::create([&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ....}设置默认值：$bond = Bond::create([&nbsp; &nbsp;'investment' => $request->input('invenstment', 'your_default_value');&nbsp; &nbsp;...]);将字段更改为空：$table->string('investment')->nullable();
