Tracing create new record problem

Hi,

I’ve done some modification of the _form.php of one of my model.

Now, when I tried to create a new record, I filled in all the required fields, click the Create button. But nothing happened. I still on the form page. No errors prompted. I tried to use the firebug, view the application.log and the web server log. Everything is normal.

How could I trace for this kind of problem?

Note: I also tried the not enter any value for the required field, the system will prompt me that field is required.

Thanks!

check <form> action and if this ok then print your post array in controller action (insert or update, depends wat you are doing) and you will see where your data is, it must be ‘ModelName[Value]’
