所以我创建了一个表单,可以将地点,类别和图片添加到我的数据库中。这一切都在我的localhost上工作正常,并将数据正确插入我的数据库。但是,当我在我的网站上放置表单时,我只是得到了“错误查询数据库”。消息。
我已经更改了连接文件,因此他们也拥有关于我的服务器,数据库名称,用户名和密码的正确信息。
我以两种不同的方式连接到我的数据库。一个使用mysqli:
<?php
$dbc = mysqli_connect("localhost","root","","ssdb") or die (mysqli_connect_error() );
mysqli_set_charset($dbc, 'utf8');
?>
另一个使用mysql:
<?php
$con=mysql_connect("localhost","root","");
mysql_select_db("ssdb",$con);
?>
在我的表单上,我正在使用mysqli函数连接到我的数据库以检索您可以选择的类别,以便一个应该正常工作?
我已经读过mysql在php版本7+上不起作用,但我的网站目前正在运行php 5.6..something。
我的表单预览可以在这里看到:http://stephanolsen.dk/imageupload/upload.php
我不知道它是否有帮助,但我的代码可以在下面看到:
我的表格:

除非您有VM,否则您可能需要使用托管公司提供给您的代码(IP地址,用户名等)连接到您的SQL数据库。
