#292

Thanks for getting back to me @yairEO

This request was more about reading and writing to a tagified text area more than using a database.

Thanks to a comment from Dinosaur Burger, I managed to write data back to the tagify textarea using - var commentHtml= tagify.parseMixTags(replyVal); //turns tags back into html.

You can find my modifications here

What I notice however is that if the same tag is repeated, when it is written back into the textarea, the second second isn't displayed properly - it shows something like this instead : {"value":"lee","title":"lee"}

How can I get parseMixTags to work properly when duplicate tags are used?

Thanks again.

@lee-matthews you need to parse the value first (using JSON.parse):

commentHtml= tagify.parseMixTags(  JSON.parse(databaseField.value)  )
