PHP errors...?

PHP errors...?

I just added a "log in - secure" form to an existing page. After I upload all the files, and try to display the page with the form on it, I get:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at D:\WAMP\www\DavesSandbox\cssform\default.php:1) in D:\WAMP\www\WA_ValidationToolkit\WAVT_ValidatedForm_PHP.php on line 3

What am I doing wrong?

Not only that - but the forms that Form Builder inserts, always seem to break my page layout (I'm testing with the DW CS5 built in CSS fixed layout pages - and there is plenty of room for the form)

the headers already sent error means that there is pout put on the page before the Session is started.

where it is reporting the issue at line 1, it most likely means that the Include Unicode signature (BOM) option has been set on your page.

Go to Modify -> Page Properties. In the Title / Encoding Section uncheck the Include Unicode signature (BOM) option.

to be able to tell what is wrong with the layout, I would need to seer the issue in the browser.

Jason -

Thanks for the reply, no it's already unchecked....our public server does not support PHP, so I included 3 screenshots with this post, which show the details...

1 - shows what the browser is showing after the page loads (before submission)
2 - shows the code in the page from DW CS5
3 - shows the resulting HTML source code from the browser

The problem is happening no matter what form I use....

Thanks for any ideas of how to fix this....

the issue is caused by the use of the virtual function for including the validation toolkit files.

change the first 2 lines:

<?php virtual("/WA_ValidationToolkit/WAVT_Scripts_PHP.php"); ?>

<?php virtual
("/WA_ValidationToolkit/WAVT_ValidatedForm_PHP.php"); ?>


<?php require_once("WA_ValidationToolkit/WAVT_Scripts_PHP.php"); ?>

require_once("WA_ValidationToolkit/WAVT_ValidatedForm_PHP.php"); ?>

In your site definition go to the Local Info tab.

there is a setting here for "Create Links relative To;"

If you select Site, Dreamweaver will use the virtual function to include files.

If you select Document, Dreamweaver will use the require_once function.

the virtual() function is problematic. It is only supported in a very few servers, where it is supported, it cases output to be added to the header causing the headers already sent error.

you should change the "Create Links relative To" setting to document so that Dreamweaver will always use the more widely supported require_once function.
