Contact Form 7 – How to hide email field in source code / development tools properly?
As website owners and developers, we strive to protect our users' personal information and maintain their trust. One common challenge faced when using the popular WordPress plugin, Contact Form 7, is the visibility of the email field in the source code and development tools. This can be a concern for users who are wary of their email addresses being exposed.
In this article, we'll dive into the various techniques you can use to effectively hide the email field in the source code and development tools when working with Contact Form 7. We'll provide step-by-step instructions and real-world examples to ensure you can implement the right solution for your website.
Understanding the Problem
The Contact Form 7 plugin is widely used for creating and managing contact forms on WordPress websites. By default, the email field is often visible in the source code and development tools, such as browser's developer tools or network inspectors. This can be a concern for users who are conscious about their privacy and the potential misuse of their email addresses.
The visibility of the email field in the source code and development tools can lead to the following issues:
- Privacy Concerns: Users may feel that their personal information is being exposed, which can erode their trust in your website and brand.
- Potential Spam and Phishing Attacks: Malicious actors could potentially scrape the email addresses from the source code and use them for spam or phishing campaigns.
- Compliance and Regulatory Concerns: Depending on your industry and location, there may be regulations or guidelines that require you to protect your users' personal information, such as the General Data Protection Regulation (GDPR) in the European Union.
To address these concerns, it's essential to find a way to effectively hide the email field in the source code and development tools while still maintaining the functionality of your contact form.
Methods to Hide the Email Field
Here are the different methods you can use to hide the email field in the source code and development tools when using the Contact Form 7 plugin:
1. Using Custom CSS
One of the simplest ways to hide the email field is by using custom CSS. This method involves targeting the email field in the contact form and applying the necessary styles to make it invisible.
Here's an example of how you can hide the email field using CSS:
.wpcf7-form-control.wpcf7-email {
display: none;
}
This CSS code will hide the email field from the user interface, as well as from the source code and development tools.
Keep in mind that while this method effectively hides the email field, it does not completely remove it from the form. The field will still be present in the form's HTML structure, but it will not be visible to users or in the source code.
2. Utilizing the wpcf7_form_hidden_fields
filter
The Contact Form 7 plugin provides a handy filter called wpcf7_form_hidden_fields
that allows you to specify which form fields should be hidden from the source code and development tools.
Here's an example of how you can use this filter to hide the email field:
add_filter('wpcf7_form_hidden_fields', 'hide_email_field');
function hide_email_field($hidden_fields) {
$hidden_fields['your-email'] = '';
return $hidden_fields;
}
In this example, the hide_email_field
function is added as a callback to the wpcf7_form_hidden_fields
filter. Inside the function, the $hidden_fields
array is updated to include the email field ('your-email'
) as a hidden field.
By using this filter, the email field will be completely removed from the form's HTML structure, making it invisible in the source code and development tools.
3. Modifying the Contact Form 7 Template Files
Another approach to hiding the email field is by directly modifying the Contact Form 7 template files. This method involves editing the plugin's internal templates to remove or hide the email field.
Here's how you can do this:
- Locate the Contact Form 7 plugin directory in your WordPress installation, typically found at
wp-content/plugins/contact-form-7/
.
- Navigate to the
templates
directory within the plugin directory.
- Open the
form.php
file, which is the main template for the contact form.
- Locate the code block that generates the email field, which should look similar to the following:
<p class="wpcf7-form-control-wrap your-email">
<input type="email" name="your-email" value="" size="40" class="wpcf7-form-control wpcf7-text wpcf7-email wpcf7-validates-as-required wpcf7-validates-as-email" aria-required="true" aria-invalid="false" placeholder="Email*" />
</p>
- To hide the email field, you can either remove this entire code block or wrap it in a conditional statement that checks if the user is logged in or has a specific role. For example:
<?php if (!is_user_logged_in()) : ?>
<p class="wpcf7-form-control-wrap your-email">
<input type="email" name="your-email" value="" size="40" class="wpcf7-form-control wpcf7-text wpcf7-email wpcf7-validates-as-required wpcf7-validates-as-email" aria-required="true" aria-invalid="false" placeholder="Email*" />
</p>
<?php endif; ?>
This approach completely removes the email field from the form's HTML structure, ensuring it is not visible in the source code or development tools.
However, it's important to note that modifying the plugin's template files directly is not recommended, as it can cause issues with plugin updates. Instead, consider creating a child theme or using a plugin that allows you to safely override the template files without affecting the plugin's core functionality.

4. Utilizing a Custom Form Builder Plugin
If you're looking for a more robust and flexible solution, you can consider using a custom form builder plugin that offers better control over the form fields and their visibility.
One popular option is the Gravity Forms plugin, which allows you to easily create and manage contact forms with advanced features. Gravity Forms provides a settings option to hide specific form fields from the source code and development tools.
Here's how you can use Gravity Forms to hide the email field:
- Install and activate the Gravity Forms plugin on your WordPress website.
- Create a new form or edit an existing one.
- Locate the email field in the form builder.
- In the field settings, you'll find an option called "Admin Label". Set this to a value that does not contain the word "email" or any other sensitive information.
- Save the form, and the email field will now be hidden from the source code and development tools.
Gravity Forms uses the "Admin Label" to identify the field internally, while the actual field label and name are used in the front-end form. This allows you to hide the sensitive information from the source code and development tools without affecting the functionality of the form.
Verifying the Effectiveness of the Solution
After implementing one of the methods mentioned above, it's essential to verify that the email field is indeed hidden from the source code and development tools.
Here are the steps you can follow to test the effectiveness of your solution:
-
Inspect the Source Code: Open your website's source code (e.g., by right-clicking on the page and selecting "View Page Source" or "View Source") and search for the email field. Ensure that it is no longer visible or has been removed from the HTML structure.
-
Use Browser Developer Tools: Open your web browser's developer tools (e.g., by pressing F12 or right-clicking and selecting "Inspect") and navigate to the "Elements" or "Sources" panel. Verify that the email field is not visible in the HTML structure or network requests.
-
Test with Different Browsers: Repeat the source code and developer tools inspection process with multiple web browsers (e.g., Google Chrome, Mozilla Firefox, Microsoft Edge) to ensure the email field is consistently hidden across different platforms.
-
Perform a Network Capture: Use a tool like Wireshark or the browser's network inspector to capture the network traffic generated by your contact form submission. Ensure that the email address is not visible in the request or response data.
-
Check the Form Submission: Submit the contact form and verify that the email field is not visible in the form's submission data or any server-side logs.
By thoroughly testing the effectiveness of your chosen solution, you can ensure that the email field is properly hidden from the source code and development tools, protecting your users' privacy and reducing the risk of potential misuse.
