Title: AJAX stops working Last modified: August 30, 2016 --- # AJAX stops working * Resolved [levonk](https://wordpress.org/support/users/levonk/) * (@levonk) * [10 years, 9 months ago](https://wordpress.org/support/topic/ajax-stops-working/) * Hi, * I am using CF7 4.2.2 for several forms. I installed PayPal Integration Add-on 1.3, but AJAX stopped working. Which not only means the page has to reload if there are fields not filled in, but also the acceptance field will not deactivate/ activate the submit button. * I tried to deactivate all plugins except CF7 and PayPal Integration Add-on with the same result. * [https://wordpress.org/plugins/contact-form-7-paypal-add-on/](https://wordpress.org/plugins/contact-form-7-paypal-add-on/) Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [Scott Paterson](https://wordpress.org/support/users/scottpaterson/) * (@scottpaterson) * [10 years, 9 months ago](https://wordpress.org/support/topic/ajax-stops-working/#post-6488885) * Hi levonk, * CF7 PayPal has to disable CF7’s JavaScript and Ajax. This is the only way to reliably get CF7 to redirect after the form has been submitted. * I am sorry about that. I spend about 2 weeks looking for an alternative solution, but I havn’t been able to find one. * Thanks, Scott * Thread Starter [levonk](https://wordpress.org/support/users/levonk/) * (@levonk) * [10 years, 9 months ago](https://wordpress.org/support/topic/ajax-stops-working/#post-6488907) * Thank you Scott. Unfortunately, this means I cannot use your plugin and I don’t know of any other plugin that will work. * When you find a solution I will happily get the pro plugin. * Plugin Author [Scott Paterson](https://wordpress.org/support/users/scottpaterson/) * (@scottpaterson) * [10 years, 9 months ago](https://wordpress.org/support/topic/ajax-stops-working/#post-6488913) * Hi levonk, * The acceptance checkbox should still work, just not disable or enable the submit button. If the user tries to submit the form without checking the checkbox they will be presented with an error. * Thanks, Scott * Thread Starter [levonk](https://wordpress.org/support/users/levonk/) * (@levonk) * [10 years, 9 months ago](https://wordpress.org/support/topic/ajax-stops-working/#post-6488914) * Hi Scott, * I was checking the CF7 docs and one of the tips defines how you can redirect to another page using the on_sent_ok hook. I have not looked into all the hooks available but I presume there could be a on_submit or on_validation_ok hook which you could use, then capture the form data somehow and then redirect to PayPal before sending the email. * Plugin Author [Scott Paterson](https://wordpress.org/support/users/scottpaterson/) * (@scottpaterson) * [10 years, 9 months ago](https://wordpress.org/support/topic/ajax-stops-working/#post-6488937) * Hi levonk, * You are correct, it would be possible to use the on_sent_ok javascript hook to redirect. However doing that still bring up a lot of other problems. * I will look into adding this perhaps as an secondary option which the user could enable. It just might be possible that I could push that hook in the array without writing it to the database… ill have to think about doing this and see if it is possible to get working without causing other problems. * Thanks, Scott * Thread Starter [levonk](https://wordpress.org/support/users/levonk/) * (@levonk) * [10 years, 9 months ago](https://wordpress.org/support/topic/ajax-stops-working/#post-6488941) * Hi Scott, * I don’t know how relation with the CF7 author is, but they seem to be friendly and take into consideration the requests. I am thinking of asking them to add more JS hooks especially a on_validate hook and possibly on_focus_out for the fields. * I still have a lot of work to do to figure out what I will need, but it seems for the PayPal integration add-on on_validate would be sufficient. * Another thought, how difficult would it be to validate the amount field through PayPal in a modal window and save the result (true, false) in a hidden field just in case other payment methods are also accepted? * Plugin Author [Scott Paterson](https://wordpress.org/support/users/scottpaterson/) * (@scottpaterson) * [10 years, 9 months ago](https://wordpress.org/support/topic/ajax-stops-working/#post-6488942) * Hi levonk, * A few questions: 1. What type of validation would happen to the amount? 2. What do you mean by modal window? 3. Do you mean a hidden input field in the CF7 form or in the CF7 PayPal form that is used in redirection? * Thanks, Scott * Thread Starter [levonk](https://wordpress.org/support/users/levonk/) * (@levonk) * [10 years, 9 months ago](https://wordpress.org/support/topic/ajax-stops-working/#post-6488949) * Hi Scott, 1. The validation would be true if paid false if not paid. I don’t know if that is the approach you have taken in the pro version. But if someone wants to allow other payment methods, like wire transfer, in addition to PayPal, then the validation should only record it in a hidden field that can be added to the email. 2. You can use the HTML5/CSS3 modal dialog or the Bootstrap JS Modal. call PayPal in an iFrame. 3. Whichever is easier to implement, as long as you can give the user an option to see the result of that field. * Plugin Author [Scott Paterson](https://wordpress.org/support/users/scottpaterson/) * (@scottpaterson) * [10 years, 9 months ago](https://wordpress.org/support/topic/ajax-stops-working/#post-6489048) * Hi levonk, * Thanks for explaining that, however I still don’t think I am understanding what you are trying to do. * The validation as you are taking about would be vary hard to accomplish for a few reasons. * 1. You can’t guarantee that the user will go back to your site. 2. PayPal doesn’t allow you to load their pages in iframes. 3. PayPal notifies your site of a completed payment via IPN. This is direct server to server and if PayPal’s servers are really busy, well I have seen it take a few hours for the IPN comes through. Even normally it can take a few minutes. Basically, there is no simple way to get a returned value from PayPal and pass it to a form. * To accomplish this, its going to take two things. * 1. A lot of custom coding. 2. I would recommending using the PayPal digital goods framework ([https://developer.paypal.com/docs/classic/express-checkout/digital-goods/IntroducingExpressCheckoutDG/](https://developer.paypal.com/docs/classic/express-checkout/digital-goods/IntroducingExpressCheckoutDG/)) this will allow you to have more of a one directional payment checkout instead of it being broken up. * Thanks, Scott * [Alessandro_77](https://wordpress.org/support/users/alessandro_77/) * (@alessandro_77) * [10 years, 8 months ago](https://wordpress.org/support/topic/ajax-stops-working/#post-6489244) * Yes, Ok Ajax does not work in pro (you should write when you sell it but it is fine, thank you anyway it is great plug-in). The issue for me now it is that I cannot use reCaptcha (i think because of it use Ajax or something). You can suggest some captcha that works with your plug-in? This is important * Thank you!
