Template cache and form submission problem

[Juergen]

Hello @all,

I have a problem by using the template cache on a template with a form.

On a page I have a contact form, and I have defined cache deactivating variables to prevent loading the page from cache after form submission.

I use query strings after the url: ?submit=success or ?submit=error (depending on the form validation).

If I push the submit button, the page will be reloaded always with the same query string (in my case ?submit=error, because this is my default query string after submission). After the page reload the template cache is disabled, but the form values will not be sent to my email address.

If I fill out the form once more (remember template cache is disabled at the moment) and I push the submit button everything works fine.

So it seems that the template cache prevents values from beeing submitted.

Does anyone have a working strategy to use template cache with forms?

Thanks in advance

Hi @Juergen

First of all, you have to be sure that your defined setting in cache disable variables is correct. 

To test it try to put * in GET or POST field in settings and try to submit the form.

Hi @Zeka

thanks for your response, but it is the same behavior independent if I add "submit" or "*" in the GET or/and POST field.

Not a solution but on form pages I disable template caching and opt for WireCache class for caching small bits of markup, like fetching pages and creating an <select> etc.

Thanks @abdus,

I know about this possibility, but I would prevent this. Another solution would be to load the forms via Ajax. For the moment I will leave the template cache disabled.
