set_value () not re-populating
In CodeIgniter, I had faced the form validation problem .
Specifically , the problem is set_value () not re-populating.
I ‘ve found what was the problem to read some of the questions and answers of Stackoverflow.
I was in the wrong position to write a set_value ().
I had put the source code . Try to reference .
This article I look forward to helping with someone 🙂
