我有一个表单和php处理来将文本和图像存储到服务器。我的问题是，当我提交表单时，即使我在输入框中输入值，也会将检查值存储为null
php处理：

我复制了你的代码（包括SQL），在我的机器上测试了它，除了你不记得创建的Thumbnail文件夹外，一切都很好。因此，为了创建这个目录，我在定义后添加了以下内容：
if ( is_dir( $thumb_directory ) == false) {
mkdir("$thumb_directory", 0700); // Create directory if it does not exist
}
我想问题出在环境上。首先看看你的文件是否真的被提交了。在最顶部执行此操作（exit（）是在转储$_FILES数组后终止脚本）：
var_dump( $_FILES['files'] );
exit();
这将在屏幕上打印上传文件的数组。如果文件提交正确，你应该会看到类似的东西
array(5) { ["name"]=> array(5) { [0]=> string(23) "Computer ICE Africa.JPG" [1]=> string(24) "Computer ICE Africa2.jpg" [2]=> string(27) "Computer ICE AfricaLogo.png" [3]=> string(17) "Guest - SLAB4.jpg" [4]=> string(17) "Guest - SLAB5.jpg" } ["type"]=> array(5) { [0]=> string(10) "image/jpeg" [1]=> string(10) "image/jpeg" [2]=> string(9) "image/png" [3]=> string(10) "image/jpeg" [4]=> string(10) "image/jpeg" } ["tmp_name"]=> array(5) { [0]=> string(24) "C:'xampp'tmp'php3630.tmp" [1]=> string(24) "C:'xampp'tmp'php3641.tmp" [2]=> string(24) "C:'xampp'tmp'php3642.tmp" [3]=> string(24) "C:'xampp'tmp'php3643.tmp" [4]=> string(24) "C:'xampp'tmp'php3653.tmp" } ["error"]=> array(5) { [0]=> int(0) [1]=> int(0) [2]=> int(0) [3]=> int(0) [4]=> int(0) } ["size"]=> array(5) { [0]=> int(103834) [1]=> int(95387) [2]=> int(12901) [3]=> int(204380) [4]=> int(179149) } }
如果您看到以上内容（文件名和大小会有所不同），请检查大小数组：
["size"]=> array(5) { [0]=> int(103834) [1]=> int(95387) [2]=> int(12901) [3]=> int(204380) [4]=> int(179149)
确保每个文件上传几kb。从一开始，这些文件的总数将小于1MB。试试这一切，让我们看看进展如何。
您应该检查查询错误。
我想你的问题与有关
'image1' => $file1,
'image2' => $file2,
'image3' => $file3,
'image4' => $file4,
'image5' => $file5,
应该是：
':image1' => $file1,
':image2' => $file2,
':image3' => $file3,
':image4' => $file4,
':image5' => $file5,
此外，如果您想检查查询的错误：
PDO准备语句的错误检查
去掉filter_input()函数中的第四个参数怎么样？
尝试清除数据库中的NULL默认值。然后，当您尝试插入值时，它应该会给您错误。
