Uploading Images - Single and/or Multiple

[HSKrustofsky]

I am building a basic ecommerce site for someone where they may, or may not, need to upload multiple images for what they are doing. I have my code working where it will upload multiple files, but the issue lies when they only add 1 image, or no image at all. For example, at the moment I have 3 inputs and when uploaded the image filename is saved in my database. Like I said, everything is okay when all 3 images are uploaded, but if they were to only add an image to one, the database adds empty rows for the other two.

 

For the image, the user is to put the item number of the product, and upload the image(s). Here is my code:

 

<?php
if(isset($_POST['submit'])) {
$num = $_POST['item_num'];

if(isset($_FILES['images'])) {
foreach($_FILES['images']['tmp_name'] as $i => $tmp_name){
$file_name = $_FILES['images']['name'][$i];
move_uploaded_file($tmp_name, "./images/".$_FILES['images']['name'][$i]);

mysql_query("insert into item_images (item_num, item_image) value ($num, '$file_name')");
}
}
}
?>
<form action="<?php $_SERVER['PHP_SELF']; ?>" method="post" enctype="multipart/form-data">
<label for="item_num">Enter Item#: </label>
<input type="text" name="item_num" /><br />
<input type="file" name="images[]" /><br />
<input type="file" name="images[]" /><br />
<input type="file" name="images[]" /><br />
<input type="submit" name="submit" value="Submit" />
</form>

 

Any suggestions? Thank you in advanced for any help.

you can check empty value for any image field before insert to your database

and this is the best practice
