循环内带有AND OR条件的cakephp分页

Question

我正在使用 cakephp 分页我正在使用 2 组复选框来过滤 ma​​terialtype 和 occasion 所以我编写了以下代码

public function index($category) {

if(!empty($this->params['url']['data']['filter']['materialtype']))
{
foreach ($this->params['url']['data']['filter']['materialtype'] as $v){
$conditions1[] ="(Product.materialtype LIKE '%$v%')";
}
$conditions[] = implode(' OR ', $conditions1);
}

if(!empty($this->params['url']['data']['filter']['occasion']))
{
foreach ($this->params['url']['data']['filter']['occasion'] as $v){
$conditions2[] ="`Product`.`occasion` LIKE '%$v%'";
}
$conditions[] = implode(' OR ', $conditions2);
}

}

我的以下代码正在生成这个 sql 查询

SELECT `Product`.`id`, `Product`.`category`, `Product`.`name`, FROM mydb`.`products` AS `Product` WHERE `Product`.`category` = 'Necklace' AND (`Product`.`materialtype` LIKE '%Yellow Gold%') OR (`Product`.`materialtype` LIKE '%White Gold%') AND (`Product`.`occasion` LIKE '%Traditional%') OR (`Product`.`occasion` LIKE '%Modern%')

但我正在寻找这个输出。

SELECT `Product`.`id`, `Product`.`category`, `Product`.`name`, FROM mydb`.`products` AS `Product` WHERE `Product`.`category` = 'Necklace' AND ((`Product`.`materialtype` LIKE '%Yellow Gold%') OR (`Product`.`materialtype` LIKE '%White Gold%')) AND ((`Product`.`occasion` LIKE '%Traditional%') OR (`Product`.`occasion` LIKE '%Modern%'))

Answer 1

您需要从 foreach 内的内部语句中删除内括号。并将其添加到外部，如下所示。

if(!empty($this->params['url']['data']['filter']['materialtype']))
{
       foreach ($this->params['url']['data']['filter']['materialtype'] as $v){
            $conditions1[] = "Product.materialtype LIKE '%$v%'";
       }
       $str_cond = implode(' OR ', $conditions1);
       $conditions[] = '(' . $str_cond . ')';
}

if(!empty($this->params['url']['data']['filter']['occasion']))
{
    foreach ($this->params['url']['data']['filter']['occasion'] as $v){
        $conditions2[] = "Product.occasion LIKE '%$v%'";
    }
    $str_cond = implode(' OR ', $conditions2);
    $conditions[] = '(' . $str_cond . ')';
}
