So here is my question.
Image a table. There is a field. Name of field is ProductGroups
In this field i have coma separeted values. For example like 10,20,30,40,etc...
And i wanna delete one of this values. (Only 1 value) Lets say it is the value 20.
Now, i do send this value (the 20) with form via method post.
So what i need is, to delete the "20" there. of course i know this is not a real "delete" process. Cause i dont wanna delete whole row or field. Just the one value which i send. So this is more a "update" process.
How should i do that ? I mean how must be selection from the field, the split etc...
Shortly, the record which was 10,20,30,40 (same field and coma separeted)
must be updated to 10,30,40 in the end.
Thank you for help in advance.
