devot:eeDevoted to ExpressionEngine

downloaded ProForm earlier this week and installed, all was well except notification templates weren’t rendering. saw the support post here and downloaded 1.05. updated, and my notifications are now rendering but I get the following php error after submitting the form.

Message: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/voltavolare/admin/expressionengine/third_party/proform/libraries/proform_notifications.php:257)

Filename: libraries/Functions.php

Line Number: 393

You probably just need to remove the debug=“yes” parameter from your template tags. This causes additional debug output to be provided - which is printed on the line noted in the error message you provided.

Can you prove the template code you are using which causes this?

It will also be helpful to know what version of PHP and ExpressionEngine you are using.

Okay I believe I have determined what the issue was that caused this. My test environments seem to have fairly high output buffering which allowed the user of a header after output - ordinarily this would stop the output with a fairly unfriendly message, which you’ve encountered. Most other users seem to have similarly high buffering settings since I haven’t gotten a report of this yet.

Removing debug=“yes” should definitely solve this issue for you.

Since I don’t really like relying on this buffering behavior, I’ve also uploaded a new build, 1.07, which will explicitly exit after printing debug output and will print a more friendly message that indicates that you should turn off debug=“yes” if you wish to run the form normally.

thanks, I’ll download 1.07 and give it a shot. fyi, I wasn’t getting any kind of debug message previously, even with debug on.

and thanks for your quick reply on a saturday morning! we’ve just launched a new site for a small airplane manufacturer and they’re getting a high degree of interest. the main channel right now for that interest is through a couple web forms, so this is a vital function for them.

yeah, something’s still up and I’m getting the debug notice below.

as I said, I wasn’t getting a debug notice at all in the previous version, even with debug on. I’ve turned debug off now, so my config looks like this.

$config[‘debug’] = “0”;
$config[‘template_debugging’] = ‘n’;

and here’s my stock notification template:

Yes, the version that you were using previously did not correctly print the entirety of the debug output without some other switches set elsewhere in the code, but it did attempt to do so - which caused the output to be flushed and prevented the redirect header from being used.

The new version forces the output to be flushed, and exits, so that you can view it (if needed) and also so you know to remove the debug parameter.

I may have been a bit unclear, sorry about that, the debug parmeter is part of your form template (you do not need to change anything in config.php or in your notification template). The sample templates in previous versions incorrectly included this parameter:

You need to remove the debug=“yes” part from your form tag in order to stop the debug output from being printed.

Hi dvn,

Just checking - were you able to resolve your issue by removing the debug parameter?

yes I was, thank you!

No problem, please post again if you have any questions!
