I'll close this ticket. </p> https://legacy.forums.gravityhelp.com/topic/dynamic-calculations#post-167878 Mon, 11 Mar 2013 13:05:53 +0000 rcDev 167878@https://legacy.forums.gravityhelp.com/ <p>Hi, I am trying to do a calculation using other fields as parameters. </p> <p>I need FLOOR. So I can't use the simple BEDMAS formulas allowed in GF. </p> <p>I found several references to using hooks and JS to accomplish this, like this one:<br /> <a href="http://www.gravityhelp.com/forums/topic/calculation-issue-1#post-144801" rel="nofollow">http://www.gravityhelp.com/forums/topic/calculation-issue-1#post-144801</a></p> <p>However, I am coming up short on solving the problem. Currently, I am using a *Product Field* and the <code>gform_field_value_{parameter_name}</code> hook. I can change the price to something static but can't seem to access any other fields using <code>rgpost</code> or <code>rgget</code>.</p> <p>I can use <code>rggpost</code> during <code>gform_pre_render</code> to get these values but not in <code>gform_field_value_{parameter_name}</code>. Are we not meant to be able to obtain form information from this hook? </p> <p>That seems weird.</p> <p>I looked in <code>forms_model.php</code> and in the function <code>get_parameter_value</code>, they are using <code>rgget</code> to obtain the value to be filtered. And in the function that calls that, <code>get_input_value</code>, they are using <code>rgpost</code> to obtain values by the standard form <code>input_{field_ID}</code></p> <p>So it works before the filter gets called but not during? </p>
