Capturing Page URL from CF7

December 4th, 2012 Leave a comment Go to comments

This only applies if you are using Contact Form 7.

Situation: you have a form defined with Contact Form 7 and it appears on more than one page. You wish to capture the page URL in the form submission.

Solution (Experimental):

Using the technique described in Changing Form Data Before it is Saved create a filter like the following.

  • Assumes that your site addresses posts using “?p=postid” in the URLs.
  • Change the value of $urlBase in line 9 to be your site’s URL
  • Change ‘page’ in line 10 to be the name of the new field to contain the URL

function set_cf7_page_url($formData) {
    if ($formData && isset($formData->posted_data['_wpcf7_unit_tag'])) {
        // Parse out the post id from the _wpcf7_unit_tag field
        // example: [_wpcf7_unit_tag] => wpcf7-f590-p1533-o1
        // where the post id is "1533"
        $pieces = explode('-', $formData->posted_data['_wpcf7_unit_tag']);
        if (count($pieces) >= 3) {
            $piece = substr($pieces[2], 1);
            $urlBase = 'http://blog.michael-simpson.com/?p=';
            $formData->posted_data['page'] = $urlBase . $piece;
        }
    }
    return $formData;
}
add_filter('cfdb_form_data', 'set_cf7_page_url');

    Hi Michael! First of all, thank you for such a great and useful plugin :)
    I just tried your solution and it works perfectly!!!

    I was wondering if instead of parsing the wpcf7_unit_tag, is it possible to store the Page Title/Name? Like for example, using any of the CF7 Tags like these: http://contactform7.com/special-mail-tags/

    I suppose that [_post_name] or [_post_title] should work, but I tried replacing _wpcf7_unit_tag with those tags and it didn’t work. I’d be grateful with your help to discover what I’m doing wrong. Have a great day!

      I took a quick look at that. I put all those tags in the mail section of a default CF7 form. Then I took a look at the data structure that gets pushed to my plugin. Unfortunately, it lists those tags, but not their values.

      I did this using the debug technique described on the page about filtering data at the bottom (I just updated that w/more info), I have the data structure writing to a log file. I encourage you to do the same so you can see all the data that is available and its format.

    Hi Michael! Thanks for your answer :)
    I did this: I created a php.ini file inside the plugin directory, inside this file I only added the path: error_log=/home/interexp/error_log.txt
    The error_log is located at the same level than my public_html file.
    Then I added the function to my functions.php file and sent the email. The form is working correctly but nothing happened with the error_log, nothing was recorded. Maybe I should be doing something wrong.

    Is there any filer or tag like the _wpcf7_unit_tag that could be used to grab the ‘friendly-url’ instead of the page ID? Because it doesn’t need to be the Page Title, with the friendly URL everything would be solved :)

    Thanks for your help again Michael.

      Not sure what the problem is writing to the log file. Might try creating a blank file and ensuring write permission are set on it.

      Here is an example of what I got from a form post. That should give you an idea of the kind of metadata you get.
