XForm Upload

Hi,

Can we allow the xforms:upload to allow only image files.

<xforms:instance id="uploadinstance">

</upload>

</uploads>

</xforms:instance>

<xforms:upload ref="instance('uploadinstance')/upload/dataFile" class="upload">

<xforms:label>Upload File :</xforms:label>

<xforms:filename ref="@filename"/>

<xforms:mediatype ref="@mediatype"/>

</xforms:upload>

The above code I used. It accepts all files.But I have to accept only image files.

Thanks,

Prameela

Re: XForm Upload

Hi,

We did something similar with a bind with a constraint on the @mediatype, something like this for you:

<xforms:bind nodeset="upload/dataFile" constraint="@mediatype = 'image/gif'"/>

Note that this works only after a file has been uploaded and the @mediatype has been filled. We cannot prevent the picker from selecting files of the wrong type.

Exactly, and this is a constraint of the browser. I don't think there is anything we can do directly on the browser to stop someone from selecting a file which is not of a type you want.
