【问题描述】：
)
我一直在为我的 Laravel 应用程序设计一个表单...... 我有 3 个字段是复选框，因此作为数组发布，然后我有一个 textarea 字段，有时 3 个复选框输入中的一个会被来自 textarea 输入字段的数据淹没......这很奇怪，只会在某个时候发生因此我在数据库中得到一个长截断错误的数据...
但是我在 $request 级别添加了输入，并且可以看到复选框中的数组已经被来自 textarea 字段的数据淹没了......我无法理解为什么会这样，因为它只是有时... 而且我什至可以得到错误并返回浏览器中的页面并再次提交所有相同的数据，然后它就可以工作了.. 什么会导致这种奇怪的行为
这是我的表单所在的 Laravel 刀片
