Contact Form X

The plugin provides five form styles (themes): Default, Classic, Micro, Synthetic, and Dark.

The first three themes (Default, Classic, Micro) employ minimal, mostly structural styles. One of the benefits of using the minimal styles is that they allow your WordPress theme to set the form’s appearance. And that’s good because it helps keep your pages looking visually consistent across your site.

The last two themes (Synthetic, Dark) go much further with the stylings. The Synthetic and Dark styles will override any/most CSS applied via your WordPress theme. So if the contact form looks weird or whatever when trying Default, Classic, or Micro, try either Synthetic or Dark should do the trick.

And of course, there is an option to disable all plugin styles. So you can use your own custom CSS 🙂

By default, Contact Form X loads its assets (CSS and JavaScript) on every front-end page. So if you display a contact form in your sidebar, it will work on all pages.

Some sites prefer to have a “Contact” page, and then just display the contact form in one location. In this scenario, it doesn’t make sense to include plugin assets on every front-end page. So CFX provides a setting called “Targeted Loading” (under the Advanced tab). There you can enter the URL of the page that displays the contact form. That way, the plugin will know to load assets only on that page. This is an excellent way to help keep things optimized for performance and so forth.

In the plugin settings, visit the “Appearance” tab. There you will see the first option, “Form Style”. That tells you which styles are used for the form. So to change the button color, scroll down to locate the styles that you are using (e.g., Default, Classic, Micro, et al). To change the color of the submit button, add the following line to whichever styles you are using:

#cfx .cfx-button { background: red !important; }

Change the red to whatever color you want. Can use hex values, rgba, or any valid CSS properties. Save changes and done.

Visit the Advanced tab and enable “Extra Email Info” option. Save changes and done.

The recommended way to defer or async load JavaScript is to use a trusted plugin or custom script.

It is possible to set a maxlength attribute on the Message field, a textarea. To do so, add the following code via (child) theme or custom plugin:

function contactformx_textarea_maxlength($chars) { return 500; }
add_filter('contactformx_textarea_maxlength', 'contactformx_textarea_maxlength');

You can adjust the number of characters by changing 500 to any number.

Enable the Advanced option, “Widget Shortcodes”. Save changes and done.

By default, the Google reCaptcha field is displayed in English. To change that to some other language, first locate the two-digit abbreviation for your language here. Then add the following code to your theme (or child theme) functions.php, or add via simple custom plugin:

function contactformx_recaptcha_querystring($query) { return 'en'; }
add_filter('contactformx_recaptcha_querystring', 'contactformx_recaptcha_querystring');

Notice where it says en, that is the two-character language code you want to replace with your own. Then save changes and done.

According to Google docs, it’s fine to hide the reCaptcha badge (the little blue badge that displays in the corner of the page), as long as the official requirements are met. So if you’ve got the requirements covered, it’s fine to add the following CSS to hide the reCaptcha badge:

.grecaptcha-badge { visibility: hidden; }

You can append that bit of CSS to your chosen form styles under the Appearance tab, in the CFX settings. Save changes and done. Or alternately, you can add the CSS using a custom plugin, or via any other method.

Contact Form X (CFX) should be compatible with any SMTP plugin that uses WP APIs and standards, etc. For example, from user reports we know that:

• CFX is compatible with Easy WP SMTP out of the box
• CFX is compatible with SMTP Mailer when the setting “Email Address From” is the same as the email set up in SMTP Mailer settings

Thanks to @sixaxis for this information.

Please let us know if you have any information about CFX compatibility with SMTP plugins, thank you.

There are two ways to customize/set the Subject line:

First way is to simply disable the “Subject” field (under the “Form” tab), and then set the option “Default Subject” (under the “Customize” tab) to whatever you want.

Second way is to add this snippet of jQuery to your site:

<script>
jQuery(document).ready(function($) {
    $('.cfx-subject').hide();
    $('.cfx-submit').click(function() {
        $('#cfx-subject').val('Whatever you want');
    });
});
</script>

Make sure to change the “Whatever you want” to.. well, whatever you want to use for the Subject field in all sent messages. No other changes need made, save changes and done.

To change the message that is displayed at the beginning of all carbon copy emails, add the following slice of code to your WordPress site:

function contactformx_send_carbon_message($message) {
    return 'This message is displayed at the beginning of the carbon copy email.'. "\n\n";
}
add_filter('contactformx_send_carbon_message', 'contactformx_send_carbon_message');

Make sure to change the return message to whatever you would like. No other changes need made, save changes and done. Just fyi, here is a guide that explains some ways to add custom code to WordPress.
