Title: [Plugin: WP Document Revisions] Adding post thumbnail support Last modified: August 20, 2016 --- # [Plugin: WP Document Revisions] Adding post thumbnail support * Resolved [bigspring](https://wordpress.org/support/users/bigspring/) * (@bigspring) * [13 years, 7 months ago](https://wordpress.org/support/topic/plugin-wp-document-revisions-adding-post-thumbnail-support/) * Hi Ben, * We’ve been using this plugin a bit recently and it’s providing some excellent functionality. Many thanks! * I have a query / bug report. Adding post thumbnail support is causing some issues, as when you set the post thumbnail for a document, the thumbnail is treated as a new version of the document you’re adding it to. * Seems like someone else (Iain Porter) reported it hereL [http://ben.balter.com/2011/08/29/wp-document-revisions-document-management-version-control-wordpress/](http://ben.balter.com/2011/08/29/wp-document-revisions-document-management-version-control-wordpress/) * Do you know of a workaround / fix for the issue? I can’t work it out from your replies on that post I’m afraid. * [http://wordpress.org/extend/plugins/wp-document-revisions/](http://wordpress.org/extend/plugins/wp-document-revisions/) Viewing 5 replies - 1 through 5 (of 5 total) * Thread Starter [bigspring](https://wordpress.org/support/users/bigspring/) * (@bigspring) * [13 years, 7 months ago](https://wordpress.org/support/topic/plugin-wp-document-revisions-adding-post-thumbnail-support/#post-3090553) * I’ve found the solution by reading through some other comments on the thread posted above, so hopefully it’ll help someone else. * Whilst in the loop, you need to query the post for any attachments and then foreach through the attachments using wp_get_attachment_image to get the actual image itself. * It’s a workaround, but works well for me and I love the fact that the document manager automatically creates post thumbnails for uploaded images. * [shortster](https://wordpress.org/support/users/shortster/) * (@shortster) * [13 years, 6 months ago](https://wordpress.org/support/topic/plugin-wp-document-revisions-adding-post-thumbnail-support/#post-3090586) * The way you describe is for fetching the thumbnail, right? * However, upon uploading the thumbnail, the document still gets overwritten with the thumbnail as a new revision. So this is only ok when you use this plugin for managing images, which is what you probably do bigspring? * So, when using the plugin for documents (pdf’s in my case), the question remains, how do we add thumbnail support without it being hijacked by the document revisions? * Thread Starter [bigspring](https://wordpress.org/support/users/bigspring/) * (@bigspring) * [13 years, 6 months ago](https://wordpress.org/support/topic/plugin-wp-document-revisions-adding-post-thumbnail-support/#post-3090587) * That’s right, I was talking about fetching the image. * To summarise what I found about adding the post thumbnail – you can’t add post thumbnail support as it will overwrite the actual download file itself. * However, if the file you uploaded if a valid image type (jpg / gif / png) then a post thumbnail is actually created without you having to specifically set one. You can then use the wp_get_attachment_image function to return the post thumbnail that’s silently created. * Plugin Author [Ben Balter](https://wordpress.org/support/users/benbalter/) * (@benbalter) * [13 years, 5 months ago](https://wordpress.org/support/topic/plugin-wp-document-revisions-adding-post-thumbnail-support/#post-3090636) * Thumbnails are not fully supported right now. This is due to a limitation on how files are uploaded. Given the media upload experience, there’s no (easy) way to know when a user intends to upload a thumbnail for a document, and when they intent to upload a new version. The workaround would most likely to be some sort of “add thumbnail” button, etc., which would bipass the normal logic of uploading a new version. * If anyone would like to take a first pass at this, pull requests are always, more than welcome. I created an issue on GitHub to track the new feature ( [https://github.com/benbalter/WP-Document-Revisions/issues/33](https://github.com/benbalter/WP-Document-Revisions/issues/33)) and will close this support thread for the time being. * Thread Starter [bigspring](https://wordpress.org/support/users/bigspring/) * (@bigspring) * [13 years, 5 months ago](https://wordpress.org/support/topic/plugin-wp-document-revisions-adding-post-thumbnail-support/#post-3090637) * Thanks for letting me know. * Although it’s probably not intended, post thumbnail support (kind of) works if you’re uploading an actual image as the document, you just need to make sure you use wp_get_attachment_image rather than the_post_thumbnail. * Obviously doesn’t work if you’re uploading a non-browser compatible image (eg. TIF) or other file type (doc / xls / pdf / etc). * Might be worth mentioning that on the documentation somewhere. It’s not ideal, but will probably keep most people going until one of us has time to submit a pull request.
