Question

我正在为opencart开发一个carousel扩展，它包含Item ID，Item Name，Link，Image，Sort Order。旋转木马有问题，保存它会更改项目ID，所以我不得不修改代码以获取查询到DB的固定ID，但现在我得到了1062错误。

注意：错误：重复输入＆＃39; 1＆＃39;关键＆＃39; PRIMARY＆＃39;错误号码：1062 INSERT INTO crousal SET crousal_id =＆＃39; 1＆＃39;，name =＆＃39; Baby＆amp;玩具＆＃39;，link = ＆＃39; /index.php？route = product / product＆amp; product_id = 7570＆＃39;，image = ＆＃39; data / carousel / banner2.jpg＆＃39;，sort_order =＆＃39; 0＆＃39;在第49行/home/user/public_html/system/database/mysql.php

分享model / carousel.php editCarousel函数

public function editCrousal($crousal_image) {

    $crousal_id = $this->db->getLastId();

    $this->db->query("DELETE FROM " . DB_PREFIX . "mobiapp_crousal WHERE crousal_id = '" . (int)$crousal_id . "'");

    if (isset($crousal_image['crousal_image'])) {
        foreach ($crousal_image['crousal_image'] as $crousal_image) {

            $this->db->query("INSERT INTO " . DB_PREFIX . "mobiapp_crousal SET  crousal_id = '" . (int)$crousal_id . "', name = '" .  $this->db->escape($crousal_image['name']) . "', link = '" .  $this->db->escape($crousal_image['link']) . "', image = '" .  $this->db->escape($crousal_image['image']) . "', sort_order = '" . (int)$crousal_image['sort_order'] . "'");

            $crousal_id = $this->db->getLastId();

        }
    }
}

任何建议我为什么会收到此错误以及如何解决此问题，谢谢您提前。

P.S。：Opencart 1.5.x

编辑：DB结构＆amp;模块信息

    $this->db->query("

我确实对此模块进行了审核。好像这个模块有完全错误的结构。正如您在方法addCrousal foreach-statement中看到的那样，插入数据库。但是在这个插入carousal_id中，表中没有递增的将是不唯一carousal_id的记录。所以这个专栏不能是主要的。我建议你用两个表重写模块＆＃34; Slides＆＃34;与关系（有很多）＆＃34;图像＆＃34;。或者您可以删除PRIMARY索引并且操作将通过，但它不是真正的解决方案。
