按子键对 Laravel jsonb 进行排序

Question

我有一个巨大的 jsonb 对象，我想按

order

对每个子部分进行排序

以

section_

开头的每个部分都有一个

order

键。

这是我在资源中尝试过的，但无法对其进行排序

class FieldSettingResource extends JsonResource
{
public function toArray(Request $request): array
{
    $fieldData = $this->field_data;

    $sections = [];

    foreach ($fieldData as $key => $value) {
        if (strpos($key, 'section_') === 0) {
            $sections[$key] = $value;
        }
    }

    // Sort the sections based on the 'order' attribute
    uasort($sections, function ($a, $b) {
        return $a['order'] <=> $b['order'];
    });

    // Overwrite original sections with sorted sections in the fieldData
    foreach ($sections as $key => $value) {
        $fieldData[$key] = $value;
    }

    return [
        'id'         => (string)$this->id,
        'name'       => $this->name,
        'field_data' => $fieldData,
    ];
}
}

这是对象的示例

Answer 1

我添加了一个嵌套的

uasort

函数来根据“order”属性对每个部分中的字段进行排序，因此它将确保您的部分和每个部分中的字段都正确排序，并且还要注意

toArray 

方法不需要接受

Request

对象作为参数，您可以简单地使用

$request

代替！

class FieldSettingResource extends JsonResource
{
    public function toArray($request)
    {
        $fieldData = $this->field_data;

        $sections = [];

        foreach ($fieldData as $key => $value) {
            if (strpos($key, 'section_') === 0) {
                $sections[$key] = $value;
            }
        }

        // Sort the sections based on the 'order' attribute
        uasort($sections, function ($a, $b) {
            return $a['order'] - $b['order'];
        });

        // Sort the fields within each section based on the 'order' attribute
        foreach ($sections as $key => $value) {
            uasort($sections[$key]['fields'], function ($a, $b) {
                return $a['order'] - $b['order'];
            });
        }

        // Overwrite original sections with sorted sections in the fieldData
        foreach ($sections as $key => $value) {
            $fieldData[$key] = $value;
        }

        return [
            'id' => (string) $this->id,
            'name' => $this->name,
            'field_data' => $fieldData,
        ];
    }
}
