I have a WordPress site with a large collection of posts and need to replace all existing embed codes inside one custom field (the video field) in bulk. I moved some videos from one file host to another, so I need to update the embed code on every post. Each post has the movie ID at the beginning. Example : ABC-123 Movie Title I have a list with the new embed codes for each post. The movie ID is also included. The list looks like this: ABC-123 "<iframe width=""600"" height=""480"" src=""https://myvidplay.com/e/******"" scrolling=""no"" frameborder=""0"" allowfullscreen=""true""></iframe>" With this project, I would like to try with few posts so I can do it myself later if I need to. Thank you.
