Customize Validating FileExtension Attachment
Good day everyone,
I wonder if the attachment from the PEGA can be customize by file extension? From another reference post they said to OOTB Filepath or using pyFileAttachment.
I've already check the Control:FilePath and it used 2 parameters to implements a file browser.
SetEncodingNow - Set to truei if File encoding should be updated immediately and pySetValueFromFileName -- specifies an element to be updated with the selected filename via an onchange event if the element is empty.
So do I need to add another parameter for my input validate file extension or do I need to make Java activity to customize it?
Best Regards,
Jimmy

First this is mainly involved Java activity inside class Data-WorkAttach-File named pyUploadFile.
Beware if you not sure what do you want to change, don't change it.
ClipboardPage cpThread = tools.getThread().getThreadPage();
ClipboardPage cpRequestor = tools.getRequestor().getRequestorPage();
ClipboardPage cpProcess = tools.findPage("pxProcess");
String exPath= cpProcess.getString("pxServiceExportPath");
String hiddenFileName= tools.getParamValue("hiddenFileName");
String pyCategory="";java.util.StringTokenizer st = new java.util.StringTokenizer(hiddenFileName,";");
while (st.hasMoreTokens()) {String currentFile =(String)st.nextToken();
if("".equals(currentFile))
continue;
exPath= cpProcess.getString("pxServiceExportPath");
int indexOfSeparator = currentFile.lastIndexOf("\\");
if(indexOfSeparator > 0){
currentFile=currentFile.substring(indexOfSeparator +1);
}
else{
indexOfSeparator = currentFile.lastIndexOf("/");
currentFile=currentFile.substring(indexOfSeparator +1);
}
exPath+=currentFile;

In the Java Activity, Pega make Copies from the selected files into the clipboard as a page list. This will be used in pzMultiFile path control, which triggers this activity to copy the chosen files data as a page list into clipboard.
In my case, I need to make validate within the file attachment type, so in this line:
String filetype = file.substring(file.lastIndexOf('.') == -1 ? file.length() : file.lastIndexOf('.')+1,file.length());//String)(hmFileInfo.get("FileExtension"));
You got the file name also the file type of the extension, just add another validation before this line:
//This is yours validate code (For Example: if ( filetype == '.pdf ' || filetype == ',jpeg '){ )
filesList.add(FilePage);
This will prevent the action of 'attachment file'.
Hope it will help you guys!

Hi
Have a look at the control pyWordDocumentFilePath
Specially if you see this lines :
accept="application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document
So basically you have to use accept attribute.
So if you want to restrict user for some specific set of files then you have to create your own custom control and modify the accept attribute accordingly

I already to change pyWordDocumentFilePath as Save as
and change the line :
accept="image/jpeg,image/gif,image/png,application/pdf,image/x-eps"
but still same. If i attach a file .txt extension, there is no validation.
Any idea?
Best regards,,
