php 开发过程中remark

1,

if (!mysqli_query($con, $createTableSql))
{
    $msg .= "table create fail:".mysqli_error($con);
}

一直报错：

"table create fail:You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'CREATE TABLE `config_os` (`id` int(11) unsigned not null AUTO_INCREMENT, `projec' at line 1"

原因：mysqli_query要把多条语句分开执行才行．

 

2, js 报错：TypeError: $(...).autocomplete is not a function

原因是jquery加载了多次，　且最后一次后面没有再加载

jquery-ui.js
