With this tutorial, we will use a function that will allow you to duplicate a WordPress post without using a plugin. Admins can easily duplicate a draft to save time.<\/p>\n

It is important to understand that while duplicating is a time-saver, we have to be careful with the next post. We need to double-check the URL’s slug in the duplicated post because it will have the same URL with a -2 appended to it meaning you’ll need to tailor it based on the newest post.<\/p>\n

In our function if we do an isset get post<\/strong>, we’ll first validate if the user has admin rights. And then we fetch the previous post’s attributes and afterwards we use wp_insert_post<\/a> in order to recuperate taxonomy and category information. Finally, we validate and fetch all of the posts’ meta and add them into an SQL query. <\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

We noticed that once the requirements have been filled, we enable the filter where we need it. In this case, we have two filters: post_row_actions<\/a> and page_row_actions<\/a>. One for the post and the other for the pages meaning that duplication will be enabled for both types.
\nIf you want to do it for another post type such as Portfolio or testimonial, you’ll a filter similar to this: add_filter( \u2018nomdutypedepost<\/strong>_row_actions\u2019, \u2018themepress_duplicate_post_link\u2019, 10, 2 ); after the two other filters.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"With this tutorial, we will use a function that will allow you to duplicate a WordPress post without using a plugin.
