uploading pictures to Mysql with PHP.

[Grimmerson]

I have a piece of code that isn't working. I'm trying to upload a few pictures to my database code is as follows:

Upload Form:

<input type="hidden" name="supplier_number" value="<? echo ''.$_REQUEST["supplier_name"].'' ?>" />
<tr>
<td>Picture 1:
<td><input type="file" name="image1[]" />
<tr>
<td>Picture 2:
<td><input type="file" name="image2[]" />
<tr>
<td>Picture 3:
<td><input type="file" name="image3[]" />
<tr>
<td>Picture 4:
<td><input type="file" name="image4[]" />
<tr>
<td colspan="2"><center><input type="submit" value="Add Pictures" name="submit" /></center>

And the code to process it is:

	$image1 = chunk_split(base64_encode(file_get_contents($_FILES["image1"]['tmp_name'])));
	$image2 = chunk_split(base64_encode(file_get_contents($_FILES["image2"]['tmp_name'])));
	$image3 = chunk_split(base64_encode(file_get_contents($_FILES["image3"]['tmp_name'])));
	$image4 = chunk_split(base64_encode(file_get_contents($_FILES["image4"]['tmp_name'])));
	$query = "UPDATE producthold SET image1 = '$image1', image2 = '$image2', image3 = '$image3', image4 = '$image4' WHERE supplier_number = $_REQUEST[supplier_name]";
	$result = mysql_query($query);

Everytime I try and use the code I get the error:

Warning: file_get_conten ts() [function.file-get-contents]: Filename cannot be empty

I'm sure its a minor mistake but I just can't figure it out (still a touch new at writing PHP).

you define the input fields as array, so the access would be $_FILES["image1"][0]['tmp_name'].

besides that, you can save the images as binary data in MySQL.
