Your Demo Does Not Show Valid Sourcecode - Custom Fields

Thank you for this report. We will check our source codes for PHP and JS on the demo site. Sorry for the inconvenience.

As for submitting additional form. You should set additionalFormName property in the BeforeUpload event. Please look at my code snippets:

PHP Library

<script type="text/javascript">
function Uploader1_BeforeUpload(){
    value = "Folder1";
    $au.uploader("Uploader1").metadata().additionalFormName("name", value);
}
</script>


<?php
    $Uploader = new Uploader("Uploader1");
    //...other params...
    $Uploader->getClientEvents()->setBeforeUpload("Uploader1_BeforeUpload");
    //...other params...
    $Uploader->render();
?>

JavaScript

function Uploader1_BeforeUpload(){
    value = "Folder1";
    $au.uploader("Uploader1").metadata().additionalFormName("name", value);
}


$au.uploader({
    id: "Uploader1",	
    // ...other params...
    events: {
         beforeUpload: [Uploader1_BeforeUpload],
    //...other params...
    }
})

Also, you can download Image Uploader 7 SDK, where you will find complete source code for Auxiliary data upload demo sample. If PHP Library is used:

C:\Program Files (x86)\Aurigma\Image Uploader 7.0.37\PHP\Samples_ImageUploaderPHP\FileUploadDemo\AuxiliaryDataUploadDemo

or here for JavaScript:

C:\Program Files (x86)\Aurigma\Image Uploader 7.0.37\PHP\Samples_ImageUploaderJavaScript\FileUploadDemo\AuxiliaryDataUploadDemo

In case you have any additional questions or problems, please feel free to let me know.

Best regards,

Dmitry Obukhov
