Conflict with WooCommerce plugin

Can I see the actual site?

Hi man,

I test on my localhost.
Just set up a new wordpress site. You install WooCommerce plugin and your Contact Form 7 plugin. You enable Debug in wp-config.php and you will see error as shown in my screenshot https://postimg.org/image/fjxzpcsj5/

Regards,

I tested the combination and confirmed it works with no error.

Did you enable Debug in wp-config.php file?
define(‘WP_DEBUG’, true);

I tested the combination and confirmed it works with no error.

I can reproduce it, with only WooCommerce 2.4.6 and CF7 4.3 loaded.

[21-Sep-2015 06:19:41 UTC] PHP Notice: get_cart was called incorrectly. Get cart should not be called before the wp_loaded action. Please see Debugging in WordPress for more information. (This message was added in version 2.3.) in /Users/jasonhendriks/Sites/wordpress/wp-includes/functions.php on line 3623

Don’t know if it helps, but here’s a backtrace:

I tried to trace where the Ajax call comes in but I could not find it. Submitting the form with Javascript disabled does not produce the warning message. It’s only triggered by the Ajax call.

I can reproduce it, with only WooCommerce 2.4.6 and CF7 4.3 loaded.

Same thing for me here.

Hmm… Still can’t reproduce it. Maybe something is different on my environment.

Anyway, can you test it with changing a line in Contact Form 7’s code?

In contact-form-7/includes/controller.php line #3

add_action( 'init', 'wpcf7_control_init', 11 );

to

add_action( 'wp_loaded', 'wpcf7_control_init' );

Do you still see the error with this change?

Maybe something is different on my environment.

Or a WooCommerce setting.

Do you still see the error with this change?

The error no longer occurs with this change.

FYI, the problem is triggered by the exit() call that is made by CF7 on the init hook. WooCommerce is probably not ready to be exited at this point hence the error. When I replace the contents with a simple return the error also goes away. Hooking on wp_load seem to be the right event at which to execute and die.

add_action( 'init', 'wpcf7_control_init', 11 );

function wpcf7_control_init() {
	return;
}

Hello there,

to be honest I do not understand the 90% of the topic discussed in this forum, therefore my question will look stupid but I don’t know anywhere else I could ask.

Is it possible to create a form that somehow it is carrying some information tag, id of the page where is coming from ?

Being more specific I need from a product page to compile a form that sends an email containing the reference of the product where the form has been compiled.

Does it make sense ?

Is it possibile and, if yes how ?

Thanks for the attention,

Roc

I had the same problem and Takayuki Miyoshi’s

sorry I do not realize I was writing on this topic.

Where can I find this comment ? Clicking on the link it bring me to the comment on this post that buzztone rightly pointed out is related to something different.

@194roc – teledirigido is contributing to the question asked by the OP (original poster). He is not answering your question. You probably find things simpler if you ignore further posts in this thread at this stage.

Thank you for testing. Maybe I’ll change the action hook to wp_loaded since it’s almost equivalent to init and seems to make no trouble with WooCommerce.

+1 for changing the action hook to wp_loaded – this could also help to avoid conflicts with the many plugins that hook to init in a way that causes problems for other plugins.
