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，将原始代码替换如下:

/**
* 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;
}
