Thanks for the positive feedback on the plugin and for your question. I want to make sure I understand what you mean by “include an xls document in the library.”
Are you having trouble uploading these documents to the Media Library? By default, WordPress and MLA enable uploading xls, xlsb, xlsm and xlsx file types. If that’s not working, make sure they are listed as “active” in the Settings/Media Library Assistant Uploads tab submenu table.
Are you having trouble including these documents in an [mla_gallery] display? If so, you may need to add a MIME Type specification to your shortcode parameters. You can find the appropriate MIME Type values in the Settings/Media Library Assistant Uploads tab submenu table. For XLS documents the appropriate parameter would be:
post_mime_type=application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
I know that’s an eyeful, but that’s what WordPress specifies. Don’t forget to add post_parent=all to the shortcode to return all matching items in the Media Library, not just those attached to the current post/page.
I will leave this topic unresolved for now. Let me know if I have not understood the question. Any additional details you can provide will be helpful. Thanks for our interest in the plugin.
