<apex:inputFile value="{!attachment.body}" fileName="{!attachment.name}" id="file" contentType="{!attachment.ContentType}" accept="image/*,application/pdf"/>

If I call this from my desktop browser, I'm only able to chose files that match the criteria of accept and the ContentType is for example set to image/jpeg. That's fine.

Called from my Nexus 5 via Salesforce1, I can select any other file type and the contentType is not correctly set. The ContentType is always set to application/octet-stream.

EDIT Controller Method:

public PageReference doAddAttachment() { 
    PageReference result;
    attachment.OwnerId = UserInfo.getUserId();
    attachment.ParentId = expense.Id;
    attachment.IsPrivate = true;
    if(attachment.body != null) {
        try {
            insert attachment;
            result = new PageReference('/apex/expenseViewMobile?id=' + expense.Id);
            result.setRedirect(true);
        } 
        catch (DMLException e) {
            ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR,'File upload failed.'));
        } 
        finally {
            attachment.body = null;
            attachment = new Attachment(); 
        }
    }
    else {
        ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR,'You need to select a file.'));
    }
    return result;
}
  • do you have controller code written ? – Mohith Shrivastava Jun 11 '14 at 15:14
  • sure, I added the controller method in my post – David Renz Jun 12 '14 at 7:37

Why not just use javascript and the ajax toolkit instead with a regular html5 input file that also has accept

note this will also allow you upload file up to 25mbs instead of 10mb with apex:inputfile

 <apex:form id="form_Upload">
 <apex:pageBlock >

  <apex:pageBlockSection columns="1">

    <apex:pageBlockSectionItem >

      <input type="file" id="myuploadbutton" accept="image/*,application/pdf"/>

    </apex:pageBlockSectionItem>

  </apex:pageBlockSection>
       <apex:pageBlockButtons location="bottom"> 


      <input type="button" id="uploadBtn" value="Attach File"/>
      <apex:commandButton action="{!back}" value="Cancel" /> 
      </apex:pageBlockButtons>
 </apex:pageBlock>
