如何在Laravel中的表中针对json编码数组检查字符串？
我在Laravel项目中遇到问题。我有一些计算机规格复选框，我想对照我称为tech_specs的数据库字段进行检查。 tech_specs字段包含该特定产品可用的所有tech_specs的序列化数组。我只想列出具有特定规格的产品。还有一件事情，我将产品分为3个等级类别，目前所有产品都位于3级等级中。我正在尝试根据url参数检查特定三级类别的规格。请让我知道如何进行。

我不确定我是否理解正确，但似乎您的数据库中有一个字段，我们称其为“ tech_specs”，其中包含“ serialize array”，当有人检查您的规格时，您想对其进行检查前端。
好吧，您不能使用简单的“ LIKE”来进行检查吗？
类似的东西：
$user_input_spec = $request->input('spec');
$result = Model::where('tech_specs', 'LIKE', '%'.$user_input_spec.'%')->get();
那不行吗？
