Re: Cannot run my if statement

Posted 05 July 2010 - 08:50 PM

I use php 4.3.1, mysql, and xampp
I have a database name dspi and table name tbllogin and it has a field Username and Department, I have a 10 departments including accounting, engineering, etc. Then i create a webpage for choosing what department they want to go. I use list value. I want that if they choose accounting and they click the submit button they automatically go to accounting webpage. I don't know how can i do that.

this is my code:
form.php

*Moved to PHP*

The 'Programmers' sub forums are for more 'discussion' oriented threads rather then 'help' threads.

Also, code tags are BBcode (i.e. they use brackets rather then html '<>')

I know from your other thread that you've been using IIS (though I don't recall waht version, or if you even mentioned the version). Have you checked to make sure PHP errors are being logged appropriately? It's quite common for PHP errors to be squelched by IIS by default as a security measure. there's a thread here that could be useful to you in making sure you're not encountering any errors.

You 1) submit the form to PHP, 2) have PHP fetch the option from the submitted form and execute a query against your database, and 3) print out any results or use header('Location: ...') to redirect.

Try it. See how far you get. Let us know if you have more targeted questions. (And keep in mind: we like code examples, preferably inside [code] tags; error messages; and detailed explanations.)

As I mentioned above, you could be getting an error and your web server's configuration could be preventing them from displaying (or even logging). Please check out the link I posted above as it is relevant to your problem (although the method for fixing it could be slightly different if you're using a different version of IIS than 7).

Are any PHP pages working at all on your server (I notice there are multiple reports of errors running PHP5 on IIS 5.1). Also, check php.ini to ensure the log_errors directive is set to On.

header() is the generally accepted way to do it. It just occurred to me something that I've overlooked, as well. You should ensure any script you're running that calls header() doesn't have any output (including whitespace such as spaces, tabs, or line breaks) before the header() call, as by then the headers will have already been sent, and so you cannot alter them or add any.

Yesterday, I use php4.3.10 and i run my webpage but now i used php 5.3.2 I encountered this problem. I don't know if I have a problem in my IIS and PHP installation.

This post made me think you were using PHP 5.3.2. The comments about header() and no output beforehand, and checking the log_errors directive still apply.

You can use meta refresh, but it's frowned upon because it can be disabled on the clients browser so it isn't a guaranteed way to assure a page move.
