说明
如您所见,我的每个产品都有相同的数据字段,而其中一些字段是相同的,例如,在 options
中,两个产品都具有 Color
或>变体
都具有 cpu
或 brand
都是相同的,最终结果中我只需要具有1个 Color
和1个 cpu
和1个相同的品牌.
Explanation
As you can see each of my products has same fields of data and some of them are the same, for instance in options
both products have Color
or in variations
both have cpu
or brand
of both is the same, in final results I need to have only 1 Color
and 1 cpu
and 1 brand as they are the same.
这是上面的代码返回的方式
This is how code above returns
$data = [];
foreach($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:最终结果是将所有产品数据合并到
单个数组
中,但唯一值.这就是我想要的.
Note: the final result is a
merge of all products data
intosingle array
, but unique values. That's what I'm looking for.
有什么想法吗?
最终结果样本将是这样
finalResult: [{,…}, {,…}]
0: {,…}
brand: {id: "fe877b45-8620-453a-8805-63f0cbd80752", name: "No Brand", slug: "no-brand", description: null,…}
0: {id: "fe877b45-8620-453a-8805-63f0cbd80752", name: "No Brand", slug: "no-brand", description: null,…},…] // it was same in both products
options: [{id: "324af955-1aa9-42ea-be6e-bb4e5623a97a", parent_id: null, name: "Need Insurance?",…},…]
0: {id: "324af955-1aa9-42ea-be6e-bb4e5623a97a", parent_id: null, name: "Need Insurance?",…}

更新2
获取数据子级
选项和变体都有子代(即 Cpu => [Core i7,Core i3]
)或 color =>['red','black']
,所以我需要收集这些孩子并将其放在其父母数据下.
Options and Variations both have children (i.e Cpu => [Core i7, Core i3]
) or color => ['red', 'black']
so I need to collect this children's and put them under their parents data.
选项模型
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
}
变量模型
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:您可能了解到,父母与子女之间的关系是由
parent_id
列定义的.

您可以使用reduce这样在一次迭代中实现所需的数据:
You can achieve what you want in one iteration over the data using reduce like so:
$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']);
}
}
foreach ($filter['tags'] as $tag) {
$tag['name'] = strtolower($tag['name']);
if ($result['tags']->where('name', $tag['name'])->isEmpty()) {
$result['tags']->push($tag);
}
}
foreach ($filter['variations'] as $variation) {
$variation['name'] = strtolower($variation['name']);
$variationName = $variation['name'];
$children = collect($variation['children'])->pluck('name');
if ($result['variations']->where('name', $variation['name'])->isEmpty()) {
$result['variations']->push($variation);
$variations[$variationName] = $children;
} else {
$different = $variations[$variationName]->diff($children);
if ($different->isNotEmpty()) {
$result['variations']->push($variation);
foreach ($different as $childName) {
$variations[$variationName]->push($childName);
}
}
}
}
return $result;
}, collect([
'brands' => collect(),
'options' => collect(),
'ratings' => collect(),
'tags' => collect(),
'variations' => collect()
]));
如果需要将结果作为数组,则可以使用集合的toArray方法:
If you need the result as an array, you can use the collection's toArray method:
$result->toArray();
