Calling a script to trigger writing ID Tag to mp3

Dear Thomas,
I call the Create Sermons Automatically URL after copying mp3 files to the audio folder. Then I have written some programs to modify the field title, series_id values of sermon_sermons table. Now I want to trigger writing ID3 tag to that sermon so that the tag values and table values are synchronized, before I do further processing on the mp3 files.
How can I (Or, Would you implement ), so that I can make a call like this:
http://server/index.php?option=com_sermonspeaker&task=script.writeid3&sermon_id=999
to trigger writing ID3 to sermon_id=999?
Thank you for your help.

You can write your own little plugin which could do that. There is no need for me to implement some function which is only ever used by your script
You can use the GetID3 library that is shipped with SermonSpeaker to write the ID3 tags. For code examples you can have a look at how SermonSpeaker is doing it:
github.com/Bakual/SermonSpeaker/blob/mas.../tools.php#L275-L388
or
github.com/Bakual/SermonSpeaker/blob/mas...upload.php#L290-L421

Thank you. I implemented the needed function as per your advice.

Dear Thomas,

I notice that $TagData in tools.php has less fields than frontendupload.php, missing date and time fields. May I know if they are different on purpose or just bugs? Thanks.

Looks like an oversight to me. Can you try the attached version?

Dear Thomas,
I did not try your code. I just added the missing lines by myself. Thank you.
