Notice: Undefined Index...image & Caption Upload

[tunedin]

Ok so I have been adding an image upload form with a seperate upload thumbnail, that works great. The problem is now that I have added captions to the images I am receiving this error.

 

[caption1] => Caption Text Test [caption2] => [caption3] => [caption4] => [caption5] => [caption6] => [caption7] => [insert] => Insert Article )
[b]Notice[/b]: Undefined index: caption8 in [b]images_upload.php[/b] on line [b]9[/b]

 

Here is the images_upload.php is line 9.

 

<?php
$uploader = new Zend_File_Transfer_Adapter_Http();
$uploader->setDestination($destination);
$uploader->setOptions(array('ignoreNoFile' => TRUE));
$files = $uploader->getFileInfo();
$filenum = 1;
foreach ($files as $file => $info) {
$file = "photo{$filenum}";
$caption = $_POST["caption{$filenum}"];
if (isset($_POST["article_id{$filenum}"])) {
$article_id = $_POST["article_id{$filenum}"];
} else {
$article_id = NULL;
}

 

And here is the insert_images.php form I am using to insert the data. The thumbnails use a different script which resembles the images, with variables changed. It workes great, especially before I added captions to the mix, and inserts all data accordingly. I am just puzzled as to why I am getting this error.

 

<?php for ($e = 1; $e <= $thumbfields; $e++) { ?>
<p>
<label for="thumbnail<?php echo $e; ?>">Thumbnail:</label>
<input type="file" name="thumbnail<?php echo $e; ?>" id="thumbnail<?php echo $e; ?>" />
</p>
<?php } ?>
<?php for ($i = 1; $i <= $photofields; $i++) { ?>
<p>
<label for="photo<?php echo $i; ?>">Photo <?php echo $i; ?>:</label>
<input type="file" name="photo<?php echo $i; ?>" id="photo<?php echo $i; ?>" />
</p>
<p>
<label for="caption<?php echo $i; ?>">Caption for photo <?php echo $i; ?>:</label>
<input value="<?php if ($_POST && $errors) {
echo htmlentities($_POST["caption{$i}"], ENT_COMPAT, 'UTF-8');
}?>" type="text" name="caption<?php echo $i; ?>" id="caption<?php echo $i; ?>" />
</p>
<?php } ?>
