如何在数组列表中使用 Laravel Eloquent 和 LIKE 语句?
How to use Laravel Eloquent with LIKE statement in array list?
我在数组中有一些条件,例如
$category = Input::get('category');
$cuisine = Input::get('cuisine');
$veg = Input::get('veg');
$trending = Input::get('trending');
$time = Input::get('time');
if($category) $conditions['category'] = $category;
if($cuisine) $conditions['cuisine'] = $cuisine;
if($veg) $conditions['veg'] = $veg;
if($trending) $conditions['trending'] = $trending;
我怎样才能
$list = Data::where($conditions)->where('cuisine','LIKE','%'.$cuisine.'%')->get();
是否可以在此语句中输入 LIKE %
if($cuisine) $conditions['cuisine'] = $cuisine;
问题是如果我想添加这个 where('cuisine','LIKE','%'.$cuisine.'%') 几个区域需要更新。在某些情况下,如果没有美食,则无法获取所有内容
我只想对美食数据执行 LIKE 语句。
嗯,你可以分几个部分来做:
$query = Data::where($conditions);
if($cuisine) {
$query->where('cuisine','LIKE','%'.$cuisine.'%');
}
$list = $query->get();
当然,您可以通过创建 an array with this format:
[['column1', 'like', '%' . $filter1 . '%'], ['column2', 'like', '%' . $filter2 . '%']]
例如:
$fields = ['category', 'cuisine', 'veg', 'trending', 'time'];
foreach ($fields as $field) {
if ($request->get($field)) {
$conditions[] = [$field, 'like', '%' . $request->get($field) . '%'];
}
}
$list = Data::where($conditions)->get();
文档中的另一个示例:
You may also pass an array of conditions to the where function:
$users = DB::table('users')->where([
['status', '=', '1'],
['subscribed', '<>', '1'],
])->get();

更新
您刚刚更新了您的问题并表示您只想对 $cuisine
使用 like
。在这种情况下,您可以使用闭包:
->where(function($q) use($request) {
if ($request->cuisine) {
$q->where('cuisine', 'like', '%' . $request->cuisine . '%');
}
})
或者您可以使用 when()
:
->when($request->cuisine, function ($q) use ($cuisine) {
return $q->where('cuisine', 'like', '%' . $request->cuisine . '%');
})
你可以这样做,
$query = DB::table('data');
$category = Input::get('category');
$cuisine = Input::get('cuisine');
$veg = Input::get('veg');
$trending = Input::get('trending');
$time = Input::get('time');
if($category) {
$query->where('category','LIKE','%'.$category.'%');
}
if($cuisine) {
$query->where('cuisine','LIKE','%'.$cuisine.'%');
}
if($veg) {
$query->where('veg','LIKE','%'.$veg.'%');
}
if($trending) {
$query->where('trending','LIKE','%'.$trending.'%');
}
if($time) {
$query->where('time','LIKE','%'.$time.'%');
}
$list = $query->get();
希望您能理解。
为什么不将默认值指定为空值,因为它会在所有情况下传入 LIKE
$conditions['cuisine']= (isset($cuisine)&&$cuisine)) ? $cuisine : '';
嗯,您必须将查询分配给某个变量:
$query = Data::where($conditions);
if($cuisine) {
$query = $query->where('cuisine','LIKE','%'.$cuisine.'%');
}
$list = $query->get();
