数据库中遇到的操作

查询字段是json的某个值

 //获取数据库中某个字段是json中得某个值，进行查询，goods是表中字段，brand_id是json中要查詢的字段。
 //数据类型一定要对应要不然查询不出来。
 $map['json_extract(goods, "$.brand_id")'] = (int)$params['brand_id'];

查询结果进行遍历操作：

db('product_plant')->where($map)
	->order('id', 'desc')
	->paginate($limit)
	->each(function ($item, $key) use ($store_id) {
		//代码逻辑
	｝

多级下拉

if (isset($params['cat']) && !empty($params['cat'])) {
     if (count($params['cat']) == 1) {
         $shop_cat_array = model('store_category')->where(['pid'=>$params['cat'][0], 'store_id'=>$this->auth->id])->column('id');
         $cat = model('store_category')->where('pid', 'in', $shop_cat_array)->where('store_id', $this->auth->id)->column('id');
         $map['shop_cat'] = ['in', $cat];
     }
     else if (count($params['cat']) == 2) {
         $cat = model('store_category')->where(['pid'=>$params['cat'][1], 'store_id'=>$this->auth->id])->column('id');
         $map['shop_cat'] = ['in', $cat];
     }
     else {
         $map['shop_cat'] = $params['cat'][2];
     }
 }


$field = 'p.id';
$sql = db('product')->alias('p')->field($field)->where($where)->union(function ($query) use ($where,$field) {
	$query->name('store_product')->alias('p')->field($field)->where($where);
}, true)->buildSql();
$model = Db::table($sql . ' as a');
$productIds = $model->column('id');
$map['product_id'] = ['in', $productIds];




$this->request->domain()


$bill_money = db('store_bill')->where(array_merge(['comein'=>1],$w))->sum('price')
            -db('store_bill')->where(array_merge(['comein'=>0],$w))->sum('price');

查看数据库中json字段不符合json结构的：

SELECT *
FROM hzqc_product_plant
WHERE JSON_VALID(goods) = 0;
不符合json结构不能使用json_container()
mysql相关函数：json_valid()
php密码设置
$params[‘salt’] = Random::alnum();
$p a r am s [^{'} p a ss w or d^{'}] = m d 5 (m d 5 ($ params[‘password’]) . $params[‘salt’]);

SELECT * FROM hzqc_product_plant WHERE store_id = 91000003 AND json_extract(goods, " $brand_id") = 6074 SELECT * FROM `hzqc_product_plant` WHERE `store_id` = 91000003 AND goods->'$ .“brand_id”’ = 6074;

常用的一些东西可以放到commom.php中，在使用的时候直接调用

if (!function_exists('cdnurl')) {
    /**
     * 获取上传资源的CDN的地址
     * @param string $url 资源相对地址
     * @return string
     */
    function cdnurl($url) {
        return preg_match("/^https?:\/\/(.*)/i", $url) ? $url : think\Config::get('upload.cdnurl') . $url;
    }
}

//常用常量参数也可以放到common中
if (!function_exists('mall_payment_type')) {
    function mall_payment_type($code = '9') {
        $result = ['wechat'=>'微信支付', 'alipay'=>'支付宝', 'credit'=>'信用支付', 'transfer'=>'对公转账', 'deposit'=>'预付款', 'zero'=>'零元领取礼包', 'mixed'=>'混合支付'];
        return ($code == '9') ? $result : $result[$code]??"";
    }
}

//随机获取一个IP
if (!function_exists('rand_id')) {
    function rand_id(){
        $data = array(
            119.120.'.'.rand(1,255).'.'.rand(1,255),
            124.174.'.'.rand(1,255).'.'.rand(1,255),
            116.249.'.'.rand(1,255).'.'.rand(1,255),
            118.125.'.'.rand(1,255).'.'.rand(1,255),
            42.175.'.'.rand(1,255).'.'.rand(1,255),
            124.162.'.'.rand(1,255).'.'.rand(1,255),
            211.167.'.'.rand(1,255).'.'.rand(1,255),
            58.206.'.'.rand(1,255).'.'.rand(1,255),
            117.24.'.'.rand(1,255).'.'.rand(1,255),
            203.93.'.'.rand(1,255).'.'.rand(1,255),
        );
        //随机获取一个IP地址
        $ip = $data[array_rand($data)];
        return $ip;
    }
}
