Multiple files uploading in multidimensional array

Question

I have a php form with unknown number of rows where user can upload files. For this purpose I use two dimensional array.

Answer 1

There were some changes to be made, in addition to the ones in the comments. Major issues are:

1. You were trying to get both files and post data into one single array, when both $_POST and $_FILES are, in PHP nature, totally separated entities. So you're ending up trying to access a single array row when there is actually two row arrays inside both these superglobals.
2. Your $target_file was never declared, and your $target_dir has too many slashes.
3. The item 1 made you access $val the wrong way.

These are the final corrections I came up with, keeping the logic for your own environment. The explanation to each part is commented inside the code.

HTML form

	
            

	
                

			

				 File:
			
			

				
			
		
	
	    
	    
	

PHP Post Script

 900000000) { // using the proper index reference for file
            die("Sorry, your file is too large."); //die if error
        }

        // Check if there are error msg in $_FILES
        if ($_FILES['row']['error'][$val] != 0) {
            die("Sorry, your file was not uploaded."); // die if error
            // if everything is ok, try to upload file
        } else {
            // point your move_files with the final name of the actual file to be moved
            if (move_uploaded_file($_FILES['row']['tmp_name'][$val], $target_dir.'/'.$_FILES['row']['name'][$val])) {
                echo "The file ". basename($_FILES['row']['name'][$val]). " has been uploaded.
";
            } else {
                die("Sorry, there was an error uploading your file.");
            }
        }
    }

Final Output (after uploading two dummy files)

        (
            [0] => 0
            [1] => 1
        )

    [submit] => Upload
)

                    [0] => dummyfile1.docx
                    [1] => dummyfile2.mpp
                )

            [type] => Array

                    [1] => C:\Windows\Temp\php73DB.tmp
                )

            [error] => Array
                (

                    [1] => 0
                )

            [size] => Array
                (
                    [0] => 0
                    [1] => 180224
                )

        )
