At the moment I’ve CF7 installed locally.
In the web server still own cforms (deactivated), and now I’m experiencing with ‘Fast and Secure Contact Form’, but I prefer CF7, with better performance, but want less use of ressources.
I think is basic that plugin creators think about ressources consumption, because WP itself alone eats a lot of them.
It’s also basic that plugins delete all their garbage from database upon uninstalling, a very common problem (and it’s a good matter for a post, if someone finds a general method).

P.S. In my previous comment, ‘and suspect still loads in all the web pages’ means ‘and suspect scripts still loads in all the web pages’.

Thanks again

Yes correct, some things have changed again in CF7 v2.2, so the code above doesn’t work anymore right away. A few lines needs to be updated for it to work with v2.2. I’ll try to update the article soon with a version that works for the latest CF7.

Cheers,
Johan

This solution seems not to work for me.
I’ve updated that with your advice for CF7 version 2.x (mine is 2.2)
My wordpress theme is a magazine-style with a mootols/jquery gallery in the home page, theme created by JBJ (from catswhocode.com). I have no conflicts between mootools libraries and other jquery libraries.

One proof that it works or not, I think, is to remove or change the ‘contact’, or whichever it’s the name of the page where one has inserted the form. But making like that, the form loads equally!! So, I think, this solution don’t work, at least for me, and I’m sure styles still loads everywhere, and suspect still loads in all the web pages. Have you experimented with this? Or, what type of proof are you using?

Second question.
I have other two forms, not in pages but in posts inside their respective categories (this is motivated by the structure of the nav bar: I cannot put a page under a category). Is your code also useful for post’s forms, or must change code like ‘is_page’ for another expression?

P.S. In clickonf5.org there is a similar solution, using $_SERVER['REQUEST_URI'], but didn’t work either.

Thanks in advance for you attention

Joan

Great tip!
Thank you again.

Quote: In the event a child theme is being used, the parent theme directory URI will be returned, not the child theme directory URI (use get_stylesheet_directory_uri() instead)

ref.: http://codex.wordpress.org/Function_Reference/get_template_directory_uri

So, if you use a child theme, like I do, the code is this:


// Change the URL to the ajax-loader image
function change_wpcf7_ajax_loader($content) {
if ( is_page('contact') ) {
$string = $content;
$pattern = '/()/i';
$replacement = "$1". get_stylesheet_directory_uri()."/images/ajax-loader.gif$3";
$content = preg_replace($pattern, $replacement, $string);
}
return $content;
}
add_filter( 'the_content', 'change_wpcf7_ajax_loader', 100 );


Regarding the Ajax loader image, in my case, it does’t work. The path refers to the Thematic image folder instead of my child theme:
:-(

Now, for the stylesheet and the javascripts, I followed Justin Tadlock’s suggestions, and came up with this code:

`
/*
* Functions: Optimize Contact Form 7
*
*/

function deregister_cf7_js() {
if ( !is_page(‘contact’) ) {
wp_deregister_script( ‘contact-form-7′ );
}
}
add_action( ‘wp_print_scripts’, ‘deregister_cf7_js’, 100 );

function deregister_ct7_styles() {
wp_deregister_style( ‘contact-form-7′ );
}
add_action( ‘wp_print_styles’, ‘deregister_ct7_styles’, 100 );
`

Thanks for your help.

Now I need to figure out how to point to my child theme.
