For loop only inserts one filename

for($i = 0; $i < $uploadsNeeded; $i++){ 

 $file_name = $_FILES['uploadFile'. $i]['name']; 
 $file_name = stripslashes($file_name); 
 $file_name = str_replace("'","",$file_name);
 $uploaddir = "media/files/".$_FILES['uploadFile'. $i]['name']; 
 $copy = move_uploaded_file($_FILES['uplo开发者_如何学JAVAadFile'. $i]['tmp_name'], $uploaddir); 
 if($copy){ 
      $res = db_res("INSERT INTO `atest` SET `filename`='$file_name', `article`='$ArticleUri'");
  } 
}

For some reason thing only uploading one of the selected files and inserting only one filename in the database. If there a better way to go through this loop to catch all of them?

There are 3 comments above, including mine: basically they are all saying the same thing. You haven't provided enough information for us to help you diagnose the problem. So I'd recommend taking a first step to debugging:

Check the values of your variables

You can do this with either print_r for variables like $_FILES (to see what files your server is getting info on) and simple echo statements to check what directory files are being saved to. Try adding a echo $uploaddir; after you define the variable to make sure its what you expect.

Also, check the $uploadsNeeded varible; you don't show how or where you're defining it, if its not the number you expect, that could be your problem right there.

From the little information you gave us, my guess is that your problem lies within the following code:

$_FILES['uploadFile' . $i]

Try this instead and see if it works:

$filesUploaded = Upload('uploadFile', './media/files/');

foreach ($filesUploaded as $fileUploaded)
{
    $res = db_res("INSERT INTO `atest` SET `filename` = '" . $fileUploaded . "', `article` = '$ArticleUri';");
}

Here is the Upload() function you're gonna need:

function Upload($source, $destination)
{
    $result = array();

    if (array_key_exists($source, $_FILES) === true)
    {
        if (is_array($_FILES[$source]['error']) === true)
        {
            foreach ($_FILES[$source]['error'] as $key => $value)
            {
                if ($value == UPLOAD_ERR_OK)
                {
                    $filename = str_replace("'", '', stripslashes(basename($_FILES[$source]['name'][$key])));

                    if (move_uploaded_file($_FILES[$source]['tmp_name'][$key], $destination . $filename) === true)
                    {
                        $result[] = $destination . $filename;
                    }
                }
            }
        }

        else
        {
            $filename = str_replace("'", '', stripslashes(basename($_FILES[$source]['name'])));

            if (move_uploaded_file($_FILES[$source]['tmp_name'], $destination . $filename) === true)
            {
                $result[] = $destination . $filename;
            }
        }
    }

    return $result;
}

Printing the $_FILES array would be very useful for us to find possible bugs in your code:

echo '<pre>';
print_r($_FILES);
echo '</pre>';
