CalcBuilder Forum

Hi,
we've checked your page and we do see the error at the console, when clicking the pdf button. In order to see the detailed error message, you can turn on for a while the joomla error reporting setting, that way you will get the specific origin of the issue and we'll let you know how to fix.

Thanks, best regards

Hi,
ok, then we'd need to introduce some logging at the code to try to print a more detailed message. If you can share an access to your site we'll debug and find the origin of the issue. You can share a temp access at the 'private data' section of this ticket.

Thanks, best regards

Hi,
ok, we've checked at your site and found out the error is thrown at the server, before even reaching the Joomla code. The server has a restriction about the lenght of the parameters it can receive, and due to the number of fields your form has, there is a very long parameter being sent to achieve the function 'store the last user input'. If you configure the setting 'show last calculator inputs' to 'None' at the 'preferences' menu you should see your form working properly.
We'll study for future versions how to reduce/compress this parameter for a better handling of big forms trying to avoid server restrictions, but you can also ask your server support about the possibility of increasing this limit and allow more information in the request in case you want to enable this 'last calculator inputs' option.

Hi,
yes, that's the configuration field we're refering to, you'd need to disable it (set it to 'none') and the long parameter won't be sent, thus avoiding the server limit. The max_input_vars is not the one affecting you, the server has a limit about the lenght a single parameter can contain, not the number of variables that you use (16000 is far enough). For enabling this function we suggest to wait to future release of the extension, where we'll introduce some improvements about the way to send this info that hopefully will overcome server limits for very big forms.

About your questions, there are no configuration options that will create those behaviors by default, but you can create all of them using the different js code sections
a) give visual feedback that the sending process is in progress and/or c) hide the calculate button You can use the tab JS->executed on loaded page' to show a section/hide the button info when the request is sent and hide section/show button once completed.

For ex, if you add a div with id="loading" at the end of your form, it could be something like

CB(document).on("ajaxSend", function(){
CB("#loading").show();
CB("input").hide();
}).on("ajaxComplete", function(){
CB("#loading").hide();
CB("input").show();
});


b) This is not included in any version, but if you had any method to achieve this in a previous calculator, you can use the same js or php code in order to pass/recover variables and it should work because all valid js/php is available in all versions.


-Add the email address from the form to cc:
This was formerly included at the main 'To' configuration parameter, but we think having this option at the cc/bcc fields is useful as well, so we have added it, you should see it working if you upgrade to latest version.

Hope this helps, regards
