Php 尝试将映像存储到数据库时发生sql错误（已更新）
Php 尝试将映像存储到数据库时发生sql错误（已更新）,php,sql,database,upload,Php,Sql,Database,Upload,UPDATED:根据评论部分的建议，我已经更新了我的代码，现在正在使用PDO。我仍然有同样的错误。 我正在尝试将多个图像存储到数据库（phpmyadmin）。当我试图上传时，它给出了一个错误error:SQLSTATE[42S22]：未找到列：1054“field list”中的未知列“file.png” 我的数据库： 我有一个名为image_upload的数据库，其中有一个名为car_details的表，该表有一个id（int11）、car_名称（varchar 255）和imageOfcar
UPDATED:error:SQLSTATE[42S22]：未找到列：1054“field list”中的未知列“file.png”Array
(
[0] => Array
(
[name] => file.png
[type] => image/png
[tmp_name] => /opt/lampp/temp/phpJYyrQn
[error] => 0
[size] => 77776
)
[1] => Array
(
[name] => files.png
[type] => image/png
[tmp_name] => /opt/lampp/temp/phpXOLvzL
[error] => 0
[size] => 84710
)
)
试验
如何修复我提到的显示在顶部的错误？如评论部分所述。我首先将代码更改为PDO，并没有在没有任何反勾号或“”的情况下插入数据库，而是按照注释部分中的建议，在将图像插入数据库时添加了反勾号和“”
$conn->exec（“插入到（，）值（“$carname'，“$imagename”）
现在我可以将图像插入到我的数据库中。我也在这里更新了我的代码
我的代码：
试验
您没有将相应的查询插入car\u details…
。但是，我希望您不要在生产中使用roor访问（没有密码）system@B001ᛦ 抱歉，我在代码中编辑了一些内容，但在将其发布到此处之前忘记将其更改回原处。我再次编辑了代码。现在我正在使用无密码（只是为了练习）当我在现实生活中的某个地方实际使用代码时，我会添加一个密码。multi_query
与您的SQL注入问题有关，这是一个大问题。另外，修复SQL注入将修复当前的问题。这是否回答了您的问题。。。或者一个重复，但这只是把问题推向了更进一步的道路。
