Renaming Picture files and Thumbs

I first started storing picture files, and such into blobs in the database. Reading the pros, and cons of doing such a thing. I tried to store my data files into folders which the database pointed to. I followed the help examples. I did have trouble with file permissions, but have seem to corrected them.

I want to take a file in, and rename the file, and/or the thumbnail, as well as the usrName.

I can get pdf's to upload, rename, store into the database correctly, for later web retrieval. The code to do the same thing refuses to work. The file is rename but the database field won't fill. I tracked it down to my_json_encode not working. (At least I think I have.
Here is the working code, loading pdf forms, and renaming them.

============================================================================================================

// get information about uploaded files

if ($values['W9Form']<> $oldvalues['W9Form']);

{

$fileArray = my_json_decode($values['W9Form']);

// rename files make sure your file permissions are set correctly

for($i = 0; $i < count($fileArray); $i++)

{

$fileName = $fileArray[$i]["name"];

$usrFileName = $fileArray[$i]["usrName"];

// new file names for user, file, thumb

$newFileName = "userfiles/w9/W9Form".$values["BusinessName"]."_".$i.date("m_d_Y").".pdf";

$newUsrFileName = "W9Form".$values["BusinessName"]."_".$i.date("m_d_Y").".pdf";

// rename files

rename($fileName, getabspath($newFileName));

chmod($newFileName, 0766);

// store New file names into array with correct JSON format

$fileArray[$i]["name"] = $newFileName;

$fileArray[$i]["usrName"] = $newUsrFileName;

}

// update values of the fields that stores file names

$values['W9Form'] = my_json_encode($fileArray);

}

if ($values['TaxResale']<> $oldvalues['TaxResale']);

{

$fileArray = my_jsondecode($values['TaxResale']);

// rename files

for($i = 0; $i < count($fileArray); $i++)

{

$fileName = $fileArray[$i]["name"];

$usrFileName = $fileArray[$i]["usrName"];

// new file names for user, file, thumb

$newFileName = "userfiles/tax/SalesTax".$values["BusinessName"]."_".$i.date("m_dY").".pdf";

$newUsrFileName = "SalesTax".$values["BusinessName"]."_".$i.date("m_d_Y").".pdf";

// rename files

rename($fileName, getabspath($newFileName));

chmod($newFileName, 0766);

// store New file names into array with correct JSON format

$fileArray[$i]["name"] = $newFileName;

$fileArray[$i]["usrName"] = $newUsrFileName;

}

// update values of the fields that stores file names

$values['TaxResale'] = my_json_encode($fileArray);

}
return true;

This code should be the same, but it uploads .jpg's, renames them, but won't store the data into the field that points to the folder.
===================================================================================================
if ($values['Picture1']<> $oldvalues['Picture1']);

{

$fileArray = my_jsondecode($values['Picture1']);

// rename files

for($i = 0; $i < count($fileArray); $i++)

{

$fileName = $fileArray[$i]["name"];

$thumbName = $fileArray[$i]["thumbnail"];

$usrFileName = $fileArray[$i]["usrName"];

// new file names for user, file, thumb

$newFileName = "userfiles/pictures1/PN".$values["PartNo"]."".$i."_1.jpg";

$newUsrFileName = "PN".$values["PartNo"].$i."1.jpg";

$newThumbName = "userfiles/pictures1/PN".$values["PartNo"]."".$i."_1_tbn.jpg";

// rename files

rename($fileName, getabspath($newFileName));

rename($thumbName, getabspath($newThumbName));

chmod($newFileName, 0766);

chmod($newThumbName, 0766);

// store New file names into array with correct JSON format

$fileArray[$i]["name"] = $newFileName;

$fileArray[$i]["usrName"] = $newUsrFileName;

$fileArray[$i]["thumbnail"] = $newThumbName;

}

// update values of the fields that stores file names

$values['Picture1'] = my_json_encode($fileArray);

}

return true;

Why did I miss?
Thanks,
