emlog强迫症福利让文章ID连续起来

emlog的朋友多多少少遇到过已发布文章ID不连续的问题，因为我们删除的文章导致ID不能连续起来，这会让强迫症患者有点难受。

目录：include/model/log_model.php。

找到代码如下：

替换为：

/**
	 * 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;
}
