I want to change this sentence:
<iframe width="850" height="478" src="https://www.youtube.com/embed/4zH9Zca1vRM" frameborder="0" allowfullscreen></iframe>
To this:
https://www.youtu.be/4zH9Zca1vRM
I can do it for every iframe of youtube video in the database. What is the right sentence for do it? I gess something like this:
step 1. Replacing first part:
wp search-replace '<iframe width="*" height="*" src="https://www.youtube.com/embed/' 'https://www.youtu.be/' --regex
step 2. Replacing last part:
wp search-replace '" frameborder="0" allowfullscreen></iframe>' '' --regex
Is it right? I'm not sure about quotes and wildcards.
Thank you!
To update with regular expressions, be sure to escape all the forward slashes for the first argument:
$ wp search-replace '<iframe width="([0-9]+)" height="([0-9]+)" src="https:\/\/www.youtube.com\/embed\/([a-zA-Z0-9]+)" frameborder="0" allowfullscreen><\/iframe>' 'https://www.youtu.be/\3' --regex
Disregard the first two matched, since they're not important and use third match in the second (replacement) argument.
Also remember to:
$ wp cache flush
It's a good idea to do a --dry-run first to see if there are any tables affected that you might not intend to modify.
