我不想说太多,这是我的代码(我知道它不是PDO,但一旦它可以工作)。几乎一切都在运作!!!
现在我正在做日志而且我被困住了! - 更新感谢迈克尔的一些已修复!
$statresult=mysql_query($statsql, $actconn) or die(mysql_error());
也优化功能。这不适用于多个DB某些原因......
许可不想是正确的我看了几个小时,我无法理解。一切都很美妙。
代码从真实数据库中读取一些行并将它们移动到backupDB。但我想要一个cron作业和电子邮件警报,所以我做了一个简单的日志(进入一个表),但它不想工作...我甚至看不到任何错误日志。好吧:PHP警告:mysql_query():提供的参数不是第34行/home/sites/stcticketing.org/public_html/back/asu1.php中有效的MySQL-Link资源

请先修复它然后评论任何PDO,除非解决方案本身:)任何帮助将不胜感激!
答案 0 :(得分:2)
在失败的函数内部(在其他函数db_rows()
中正确完成),您的数据库资源链接变量超出范围。将它们作为参数传递给函数:
例如,在$connection
传递一个:
function test($sqls, $states, $connection){
if ($sqls=1){
$resflag=1;
}
else {
$resflag=0;
}
$statsql="INSERT INTO `web151-tevenyal`.`tex_bcklog` (`what`,`how`,`when`) VALUES ('$states',$resflag,CURDATE());";
echo "<p>".$sqls."<br/>".$statsql."</p>";
$statresult=mysql_query($statsql, $connection) or die(mysql_error());
echo "<p>".$states." - ".$resflag."</p>";
$emaltext=$emailtext.$sqls;
}
然后使用正确的连接调用函数,如:
test($permsql, "grant", $actconn);
