如何在laravel中返回唯一值
如何在laravel中返回唯一值
提问于 2020-07-17 05:42:02
这里我有这个样本数据，它基于类别产品返回，我需要限制重复的值。

您可以看到，我的每个产品都有相同的数据字段，其中一些是相同的，例如，在options中，两个产品都有Color，或者在variations中都有cpu或brand，两者都是相同的，在最后的结果中，我只需要有一个Color、一个cpu和一个品牌，因为它们是相同的。
代码
以上代码就是这样返回的。
$data = [];
foreach($products as $i => $product) {
$data[$i]['brand'] = $product->brand;
$data[$i]['rating'] = $product->rating;
$data[$i]['variations'] = $product->variations;
$data[$i]['options'] = $product->options;
$data[$i]['tags'] = $product->tags;
}注意:最后的结果是将
merge of all products data转换为single array，但是唯一的值。这就是我要找的。
有什么想法吗？

获取数据的子数据
选项和变化都有孩子(即Cpu => [Core i7, Core i3])或color => ['red', 'black']，所以我需要收集这些孩子的孩子，并把他们放在父母的数据下。
Option model
public function options()
{
return $this->hasMany(Option::class);
}
public function children() {
return $this->hasMany(Option::class,'parent_id','id') ;
}
public function parent()
{
return $this->belongsTo(Option::class,'parent_id');
}
public function isParent()
{
return !$this->parent_id ? true : false; // if parent_id is null => is a Parent Option
}Variant model
public function variants()
{
return $this->hasMany(Variant::class);
}
public function children() {
return $this->hasMany(Variant::class,'parent_id','id') ;
}
public function parent()
{
return $this->belongsTo(Variant::class,'parent_id');
}
public function isParent()
{
return !$this->parent_id ? true : false; // if parent_id is null => is a Parent Variant
}注意:正如您可能理解的，父级和子级之间的关系由
parent_id列定义。

您可以在数据的一次迭代中实现您想要的结果，可以使用如下方法：
$variations = [];
$result = array_reduce($filters, function ($result, $filter) use ($variations) {
$filter['brand']['name'] = strtolower($filter['brand']['name']);
if ($result['brands']->where('name', $filter['brand']['name'])->isEmpty()) {
$result['brands']->push($filter['brand']);
}
foreach ($filter['options'] as $option) {
$option['name'] = strtolower($option['name']);
if ($result['options']->where('name', $option['name'])->isEmpty()) {
$result['options']->push($option);
}
}
if (isset($filter['rating']['id'])) {
if ($result['ratings']->where('id', $filter['rating']['id'])->isEmpty()) {
$result['ratings']->push($filter['rating']);
}
}
