use only lowercase filenames for uploaded images

use only lowercase filenames for uploaded images

So, this one has been driving me nuts forever. I run into this problem with Data Assist File Upload on almost all my projects and have come up with all kinds of different ways of fixing this. But I have no 100% fix. Please let me know how to ensure that any file uploaded will be lower case.

So IMG1023.jpg becomes img1023.jpg

I've had limited success with strtolower() here.

<?php
WA_DFP_SetupUploadStatusStruct("WA_UploadResult1");
if(isset($_POST["Update"])){
WA_DFP_UploadFiles("WA_UploadResult1", "newimg", "2", "".strtolower(((isset($_FILES["newimg"]))?$_FILES["newimg"]["name"]:"")) ."", "JPG:80", $WA_UploadResult1_Params);
}
?>

Also, if you can suggest something to remove whitespace from file names, that would be a help too. So that "IMG the Boat.jpg" become "img-the-boat.jpg" or something.

This, by the way, works when the same image is re-uploaded. So the first time the image is uploaded, the file name remains uppercase. But the second time the same image is uploaded again, the filename is made lowercase.

I can't figure out how to use stringtolower() in the second part of this operation so that the blasted filename is made lowercase in either operation.

Yep, frustrated.

Ive got filename changing working when I update the database with the new filename so that it replaces whitespace with - and it changes all to lowercase:

"".strtolower (str_replace(" ", "-", ($WA_DFP_UploadStatus["WA_UploadResult1"]["serverFileName"]))) ."" . $WA_AB_Split . "1";

ok I have adapted the code im using to do what you wanted (strip white space AND make lowercase): Here is my code for you to compare to yours:

$WA_UploadResult1_Params["WA_UploadResult1_1"] = array(
'UploadFolder' => "../../images/banner/",
'FileName' => "".strtolower(str_replace(" ", "-", (((isset($_FILES["fileupload"])))? preg_replace('/.[^.]*$/', '', $_FILES["fileupload"]["name"]) :""))) ."",
'DefaultFileName' => "",
'ResizeType' => "0",
'ResizeWidth' => "120",
'ResizeHeight' => "120",
'ResizeFillColor' => "#FFFFFF" );
// WA_UploadResult1_1 End
// WA_UploadResult1 Params End
?>
<?php
WA_DFP_SetupUploadStatusStruct("WA_UploadResult1");
if(isset($_POST["Save"]) || isset($_POST["Save_x"])){
WA_DFP_UploadFiles("WA_UploadResult1", "fileupload", "0", "", "JPG:100", $WA_UploadResult1_Params);
}
?>

Thanks! It works. It will be nice to have this kind of change reflected in the next version of Data Assist.
