precheck checkbox from link

If I have a banner that links to a form, that has checkboxes on it, is it possible to link to the form page, passing something in the url that would check the appropriate checkbox that I want checked when the page loads?

Thanks!!

HI jrthor2,

You can add a parameter to the banner URL like &bid=999. ChronoForms will automatically add that to the $form->data array in the form On Load event so you can then use it to set a checkbox value.

and how would I set it to checked then?? What is bid=999?

Thanks

Hi jrthor2,

&bid=99 is some parameter that you add to the banner URL = it could be anything that suits your needs.

In the form ON Load event $form->data['bid'] will be set to 999 so can then use PHP to set a value for the checkbox you want enabled.

So, I gather in the wizard editor, in the Event On Load section, I need to add a Custom Code Core Action? Any chance I could get some custom code help?? :-)

Thanks!

PS But it will be different if you have a checkbox group rather than single checkboxes. If you want useful code then you need to ask specific questions with information about your form.

Yup, you're right, and it is a checkbox group? :-(

Any help is greatly appreciated!!

Thanks
