[Plugin: Contact Form 7] no documentation for developers?

I finally got a working code:

function hiddenreferer_shortcode($tag) {

	if ( ! is_array( $tag ) )
		return '';

	$options = (array) $tag['options'];
	foreach ( $options as $option ) {
		if ( preg_match( '%^name:([-0-9a-zA-Z_]+)$%', $option, $matches ) ) {
			$name_att = $matches[1];
		}
	}

	 $pageURL = 'http';
	 if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
	 $pageURL .= "://";
	 if ($_SERVER["SERVER_PORT"] != "80") {
	  	$pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
	 } else {
	  	$pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
	 }

	 $value_att = $pageURL;
	 $html = '<input type="hidden" name="' . $name_att . '" value="'.$value_att.'" />';
	 return $html;
}
wpcf7_add_shortcode('hiddenreferer', 'hiddenreferer_shortcode', true);

usage:

//use [hiddenreferer referer name:referer] in the form
//and [referer] in the email template

Ir can probably be done better (less code, more poetry).
I don’t know why the duplicity of referer name:referer is needed but it works like this…

If someone comes up with a nicer code please share.

bazinga

you can get the name by $name_att = $tag['name'], them you don’t need name:referer option any more.

sorry for the poor documentation for add-on development, I’m writting it right now.

Neat. Thank you Takayuki. Good luck with the documentation, and thank you for your time and this nice plugin ??

Thank you for this referer & info
But which file edit for add this code ?

function hiddenreferer_shortcode($tag) {

    if ( ! is_array( $tag ) )
        return '';

    $options = (array) $tag['options'];
    foreach ( $options as $option ) {
        if ( preg_match( '%^name:([-0-9a-zA-Z_]+)$%', $option, $matches ) ) {
            $name_att = $matches[1];
        }
    }

     $pageURL = 'http';
     if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
     $pageURL .= "://";
     if ($_SERVER["SERVER_PORT"] != "80") {
          $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
     } else {
          $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
     }

     $value_att = $pageURL;
     $html = '<input type="hidden" name="' . $name_att . '" value="'.$value_att.'" />';
     return $html;
}
wpcf7_add_shortcode('hiddenreferer', 'hiddenreferer_shortcode', true);

This would go in your /wp-content/themes/theme-name/functions.php file, so when you update the plugin the code doesn’t disappear.

Never hack the code of plugins. Also I recommend using child themes before changing any code on a theme.

is there a way to get IP address and User Agent too? Can the following code be added somewhere to do achieve this?

<?php
$ipi = getenv(“REMOTE_ADDR”);
$httprefi = getenv (“HTTP_REFERER”);
$httpagenti = getenv (“HTTP_USER_AGENT”);
?>

<input type=”hidden” name=”ip” value=”<?php echo $ipi ?>” />
<input type=”hidden” name=”httpref” value=”<?php echo $httprefi ?>” />
<input type=”hidden” name=”httpagent” value=”<?php echo $httpagenti ?>” />

As far as I know:
Sender’s IP address: [wpcf7.remote_ip]

That is a built-in tag you put in the mail template (right box). Let’s hope Takayuki Miyoshi’s documentation reveals all the tags that are at our disposal!

See Special Mail Tags

Perfect thank you!

These mail tags are great – didn’t know they exist, really helpful, thanks.

Found a better solution here -> https://tonykwon.com/2010/09/can-we-capture-http-referer-information-upon-form-submission-using-contact-form-7/

1. Add a Text Field element with a css class referer-page
[text referer-page class:referer-page]

2. Add the following css to your styles.css
input.referer-page { display:none; }

3. Add the following code snippets to your functions.php?

function getRefererPage( $form_tag )
{
        if ( $form_tag['name'] == 'referer-page' ) {
                $form_tag['values'][] = $_SERVER['HTTP_REFERER'];
        }
        return $form_tag;
}
if ( !is_admin() ) {
        add_filter( 'wpcf7_form_tag', 'getRefererPage' );
}

4. Add the following to the Contact Form 7 Message body (under Mail)

Referer Page: [referer-page]

I am using the do_shortcode like this:

<?php echo do_shortcode( '[contact-form 1 "Contact form 1"]' ); ?>

How do I specify the subject from this, can I do that?

Hi,

I want to capture info about what keyword they searched a Google to find and fill the form. It would be really cool to also capture my AdWords data like Salesforce’s webforms do.

Does anyone know of a way to do this using CF7?

Well that hardly sounds like a CF7 extension to me.

In Google Analytics you can see the source and keywords used to get to a page (or form). You can also relate a page (and form) to a campaign.
I thank that is the place to look for such a solution.
And you can also connect AdWords to Analytics… and you can set a form page as a target …. all in Google.

Enjoy,
