轻松解决Emlog文章删除后ID不连续的方法

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;
  }
