Title: Validation issue when checking checkbox fields Last modified: August 9, 2022 --- # Validation issue when checking checkbox fields * [lippiun](https://wordpress.org/support/users/lippiun/) * (@lippiun) * [3 years, 10 months ago](https://wordpress.org/support/topic/validation-issue-when-checking-checkbox-fields/) * Hello, * I am using Contact Form 7 v5.6.1 on my local WP 6.0.1 installation with the default Twenty Twenty Two theme. * I have noticed a bug when using checkbox fields on a contact form. The issue is when i toggle the checkbox on the frontend, it triggers a change event on the form causing all validation errors to appear. * This is not expected behaviour and the validation should only be triggered when a user has submitted the form. * If i remove the ‘change’ event handler from the WPCF form DOM element, it works as expected. * I’ve have captured a screen recording of the issue to help with your investigations. * [https://www.awesomescreenshot.com/video/10411987?key=e7b6af3dec2fce4a13f39454bbf51d60](https://www.awesomescreenshot.com/video/10411987?key=e7b6af3dec2fce4a13f39454bbf51d60) - This topic was modified 3 years, 10 months ago by [lippiun](https://wordpress.org/support/users/lippiun/).

You may have some other event handler involved, for example, but you’ll have to find it yourself or publish the site somewhere and share the public link. * Thread Starter [lippiun](https://wordpress.org/support/users/lippiun/) * (@lippiun) * [3 years, 10 months ago](https://wordpress.org/support/topic/validation-issue-when-checking-checkbox-fields/#post-15910390) * Hi Gal, * You can see the site [here](http://realbrandingtesting.co.uk/atsolutionsuk/trade-accounts/register-for-a-trade-account/) * [Gal Baras](https://wordpress.org/support/users/galbaras/) * (@galbaras) * [3 years, 10 months ago](https://wordpress.org/support/topic/validation-issue-when-checking-checkbox-fields/#post-15914582) * In your theme’s main.js, there’s a copy of [https://fellowtuts.com/wordpress/contact-form-7-radio-checkbox-bootstrap-4-style/](https://fellowtuts.com/wordpress/contact-form-7-radio-checkbox-bootstrap-4-style/), which could be the culprit. * Thread Starter [lippiun](https://wordpress.org/support/users/lippiun/) * (@lippiun) * [3 years, 9 months ago](https://wordpress.org/support/topic/validation-issue-when-checking-checkbox-fields/#post-15920401) * Hi, * The bootstrap styling script isn’t the problem as the issue still persists after removing it. * Even when i deactivate ALL plugins and switch to the default Twenty Twenty Two theme, the form is still validating after checking a checkbox. I can see the event handler for this is coming from your plugin. * Thread Starter [lippiun](https://wordpress.org/support/users/lippiun/) * (@lippiun) * [3 years, 9 months ago](https://wordpress.org/support/topic/validation-issue-when-checking-checkbox-fields/#post-15920427) * You can replicate this issue by creating a fresh WP install on the following environment: * WordPress v6.0.1 Web Server: nginx PHP Version: 7.4.1 * Theme: Twenty Twenty Two * Contact Form 7 Version: 5.6.2 * Then create a basic form with the following the fields: * ``` [checkbox checkbox-340 use_label_element "Test"] [submit "Submit"] ``` * Then, when you click on the checkbox you will the form validations appear. * [Gal Baras](https://wordpress.org/support/users/galbaras/) * (@galbaras) * [3 years, 9 months ago](https://wordpress.org/support/topic/validation-issue-when-checking-checkbox-fields/#post-15920501) * Time for [@takayukister](https://wordpress.org/support/users/takayukister/) to get involved, I guess. * Thread Starter [lippiun](https://wordpress.org/support/users/lippiun/) * (@lippiun) * [3 years, 9 months ago](https://wordpress.org/support/topic/validation-issue-when-checking-checkbox-fields/#post-15937767) * Hi, * Any update on this? * [Gal Baras](https://wordpress.org/support/users/galbaras/) * (@galbaras) * [3 years, 9 months ago](https://wordpress.org/support/topic/validation-issue-when-checking-checkbox-fields/#post-15937934) * I’ve tested it on one of my sites and the problem happens there too, so this is an issue with the plugin. I’ve even isolated it to the “change” event handler form.wpcf7-form.init in includes/js/index.js. * Unfortunately, that’s as far as I go. * [Try opening an issue for this on Github](https://github.com/takayukister/contact-form-7/issues/new/choose). * [andreaciocca](https://wordpress.org/support/users/andreaciocca/) * (@andreaciocca) * [3 years, 9 months ago](https://wordpress.org/support/topic/validation-issue-when-checking-checkbox-fields/#post-15986453) * Hi, any news on this? * I tried to open an issue request on github which has been categorized as invalid and consequently removed (you can find original post screenshot here [https://ibb.co/NKBdwRT](https://ibb.co/NKBdwRT)) * I wonder where I should ask for this then 🙂 * Thread Starter [lippiun](https://wordpress.org/support/users/lippiun/) * (@lippiun) * [3 years, 9 months ago](https://wordpress.org/support/topic/validation-issue-when-checking-checkbox-fields/#post-15986467) * Pretty crazy how I posted about this 4 weeks and the plugin developer still hasn’t answered.
