解决Emlog文章删除后ID不连续的方法教程

EMLOG在删除文章后ID就会断掉，现在只需要简单修改一下代码，后面新增文章的时候就会优先选择断掉的文章ID。

修改步骤
1、找到路径下的include/model/log_model.php文件，将原始代码如下：

 /**
    * 添加文章、页面
    *
    * @param array $logData
    * @return int
    */
    function addlog($logData) {
        $kItem = array();
        $dItem = array();
        foreach ($logData as $key => $data) {
            $kItem[] = $key;
            $dItem[] = $data;
        }
        $field = implode(',', $kItem);
        $values = "'" . implode("','", $dItem) . "'";
        $this->db->query("INSERT INTO " . DB_PREFIX . "blog ($field) VALUES ($values)");
        $logid = $this->db->insert_id();
        return $logid;
    }

2、修改为以下代码：

 /**
        * 添加文章、页面
        *
        * @param array $logData
        * @return int
        */
        function addlog($logData) {
            $kItem = array();
            $dItem = array();
            foreach ($logData as $key => $data) {
                $kItem[] = $key;
                $dItem[] = $data;
            }
            $field = implode(',', $kItem);
            $values = "'" . implode("','", $dItem) . "'";
            $gidarr[0]='0';
            $res = $this->db->query("SELECT gid From  " . DB_PREFIX . "blog ORDER BY gid ASC");
            while ($row = $this->db->fetch_array($res)) {
                $gidarr[] = $row['gid'];
            }
            foreach($gidarr as $key=>$val){
                if($key!=$val){
                    $field = 'gid,'.$field;
                    $values = "'".$key."',".$values;
                    break;
                }
            }
            $this->db->query("INSERT INTO " . DB_PREFIX . "blog ($field) VALUES ($values)");
            $logid = $this->db->insert_id();
            return $logid;
        }
