Appreciate these instructions, and the comments, especially that from Christian Schenk. I was worried about mucking with the PHP files, but your instructions were clear.

One note: make sure the single quote marks in your PHP file are _not_ smart quotes, as they appear in the comment above.

Thanks Takayuki for your continued development and improvement.

Hi Takayuki,

Thanks very much for a great plugin.

I’m trying to disable the javascript and css with the lines below, in my wp-congif.php.

define (‘WPCF7_LOAD_JS’, false);
define (‘WPCF7_LOAD_CSS’, false);

Had a little stupid mistake, putting the lines right at the bottom of the config file. It has no effect unless you put it above the line below:

/* That’s all, stop editing! Happy blogging. */

Hope this helps anyone else wondering why its not working!

Thanks.

Agree. Thank you for discussing this with me.

Because there is no better way than this. Note that many users put thier contact forms in posts (they will be shown on index page and archive pages) and sidebar widgets. In such cases, setting post meta doesn’t work.

Don’t you think that this is something a lot of people might want to do? Why not build it into the plugin?

Or, you can write an extra helper plugin on your own which does once deregister the script and enqueue it again if the post has 'cf7' meta.

It has worked for me so far because I’ve always put my forms on a separate page. Anyway, I’d love to see something like this incorporated into the plugin – adding the code after every update is quite annoying.

Looks like a nice hack. If you show a form only on a singular page (I mean, non-archive pages), this should work. Thanks Christian.

Using the most recent version (2.0.7) of Contact Form 7 you can change a little portion of the plugin to make this more flexible using custom fields. Just open the file controller.php which is located in the plugin's directory under includes and add the following code right at the beginning of the functions wpcf7_enqueue_scripts and wpcf7_enqueue_styles, i.e. right after the curly brackets on a new line: global $post; if (get_post_meta($post->ID, 'cf7', true) != '1') return; This way only posts/pages containing a custom field cf7 with its value set to 1 will load the corresponding CSS/JavaScript. Regarding the example above you should add a custom field to the page "Contact" and the form will work on this particular page.
