在PHP表单处理之后，SQL表中的所有值都为空

I have a form and php processing to store text and image to server my problem is when I submit form and check values are stored as null even if I enter values in input box

php processing:

I copied your codes ( including the SQL ) tested it on my machine and with the exception of Thumbnail folder, which you did not remember to create, things worked fine. So to create this directory, I added the following after the definition:

if ( is_dir( $thumb_directory ) == false) { mkdir("$thumb_directory", 0700); // Create directory if it does not exist }

I guess the problem is with the environment. First find out if your files are actually being submitted. Do this at the very top ( the exit() is to terminate the script after dumping the $_FILES array):

var_dump( $_FILES['files'] ); exit();

This will print array of uploaded files on the screen. If the files are properly submitted, you should see something like

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) } }

If you see the above ( file names and sizes will differ), then inspect the size array:

["size"]=> array(5) { [0]=> int(103834) [1]=> int(95387) [2]=> int(12901) [3]=> int(204380) [4]=> int(179149)

Make sure you upload files of a few kb each. The total of those will be less than 1 MB to start with. Try all this and let's see how it goes.
