Hi Jhon,
Thanks for your answer. I want to change field for several reasons but one of them is I need to create statistic and in this specific case I can’t use your solution because it’s will be very too long to edit and save all our old post.
For exemple I need to :
- Change text to select field : To made statistic I need to change text field to a select one because user never wrote value the same way. So I need to edit all the value by meta_key and depending on keywords.
I probabely can use your filter but did you know a solution to apply filter to all post (by PT for exemple) and save ? For exemple load mass change from a option page I create ?
Appart from this your function is very usefull and I probably can edit it to fit for many case.
