The Additional Setting “on_sent_ok” is used to assign a JavaScript code that will be executed when a form submission completes and mail has been sent successfully. It is often used for the purpose of tracking form submissions with web analytics services or redirecting to another page after a form submission.
The “on_sent_ok” and its sibling setting “on_submit” are deprecated and scheduled to be abolished by the end of 2017. It’s not that using those settings is unsafe, but it’s possible that enabling them will increase risk in case there are vulnerabilities in this plugin or in other components of your site. It’s time to replace them with a safer alternative.
Update: on_sent_ok and on_submit have been officially removed from Contact Form 7 5.0.
Contact Form 7 4.7 is now available. This release is mainly aimed at several internal refinements that are going to be important in the future evolution. Although it doesn’t include fixes for security issues or critical bugs, I recommend that all users upgrade as soon as possible.
Contact Form 7 4.6 is available. This release has been confirmed as compatible with the upcoming WordPress 4.7, and includes a lot of new features and improvements I’m sure you have been looking for.
The default contact form template has been modified for the first time in 8 years. The major change is the addition of label elements.
Using a label element to label a form control is recommended in accessibility guidelines. In earlier versions, the default template didn’t use label elements, so you had to add them on your own if you wanted to make your form accessible.
In the early versions released before 2008, label elements were used in their default template, but they were abandoned for a reason.
The last Sunday was WordPress Global Translation Day and we had a lot of contribution to the Contact Form 7 translation. Thank you everybody! Now we have 22 language packs available from translate.wordpress.org.
If you are using Contact Form 7 in those languages, after updating the plugin, don’t forget to go to the WordPress Updates page (Dashboard > Updates) and update translations. Enjoy Contact Form 7 in your language.
