I am trying to debug a page which posts and just shows me a blank page after posting.

The point is that is that when the post is made there are quite a many php calls after which the output is
suppose to render.

I wish to find out where exactly the code fails during these php calls.
Hence, I used this "Debug Next post" from both IE and FF.
But I am not sure how it works, the debug session starts but I still see the blank page directly without any stepping through the code.
So I am unable to see how and where the code fails.

Has anyone used this feature?

I have used the "Debug Next post" feature often. It is supposed to work the way you expect. My guess is that you do not have a valid breakpoint in your script that accepts the POST, e.g. no breakpoint on executable lines. I suggest you enable the option to "Stop on the first line after run" (Tools / Settings / Run & Debug), and see if that triggers a debug session.

Thanks.

I tried the "Stop on the first line after run" setting, but still does not trigger the breakpoint or the debug session.
May be it starts the debug session, but I am not able to step through it.

I have even added the proper break point, but it was of no use.

It just shows the blank page directly.

Does debugging work on other pages in the project? If you are not sure of this, you should try the DBG Wizard to verify that your settings are correct. See new-dbg-wizard-can-help-you-setup-remote-debugging-t3116.html for details.

You could also try the following for more clues as to why the script is outputting a blank page:
* Edit your php.ini and set error_reporting = E_ALL, display_errors = On and log_errors = On. Doing this will make PHP log all errors, warnings and notices to screen and also to an error_log file in the same directory as the script.
* In PhpED, open Tools / Settings / Run & Debug and set the Error Level to 4 - All errors, warnings and notices. This will display the same messages as above, but in PhpED itself. This will (obviously) only work if you have set up your project's debugging correctly.

I hope this helps

First you need to make sure that debugger is intalled on the server where you post to. Otherwise toolbar commands are ignored.
