This is exactly what I need, but I'm not sure what file this code needs to be added to. I know this is outside the realm of "standard" support, but this is incredibly helpful!

You can manipulate the total field with javascript all you want, but the submitted value is not used to determine the "real" total of the submission. That is why we use the product field set to user defined price. The value submitted through this field does impact the "real" total of the submission. So, with that said, here is an updated snippet that still uses the user defined price, but hides it with a little CSS, but also uses the total field to provide that information to the user.</p> <p><a href="http://pastie.org/1487231" rel="nofollow">http://pastie.org/1487231</a> </p> https://legacy.forums.gravityhelp.com/topic/dynamic-price-per-square-metre-calculation#post-16844 Sat, 22 Jan 2011 08:01:28 +0000 mrhoneyfoot 16844@https://legacy.forums.gravityhelp.com/ <p>Well that didn't work. Two more functions might be causing this. Either this one:<br /> <pre><code>function gformIsHidden(element){ return element.parents(&#39;.gfield&#39;).css(&quot;display&quot;) == &quot;none&quot;; }</code></pre> <p>or this part of the function gformCalculateProductPrice(formId, productFieldId){</p> <pre><code>if(!gformIsHidden(jQuery(this))) price += gformGetPrice(jQuery(this).val()); });</code></pre> <p>Alternatively <code>price = productField.val();</code> was not the answer. Anyone want to make a call? </p> https://legacy.forums.gravityhelp.com/topic/dynamic-price-per-square-metre-calculation#post-16842 Sat, 22 Jan 2011 07:37:49 +0000 mrhoneyfoot 16842@https://legacy.forums.gravityhelp.com/ <p>Think we might have found what's causing total price to remain at zero. </p> <p>Specifically, <code>function gformGetBasePrice(formId, productFieldId){</code> has two almost identical instances of the following inside price.js: </p> <pre><code>//If field is hidden by conditional logic, don&#39;t count it for the total if(gformIsHidden(productField)){ price = 0; }</code></pre> <p>and</p> <pre><code>//If field is hidden by conditional logic, don&#39;t count it for the total if(gformIsHidden(productField)) price = 0; }</code></pre> <p>Should <code>price = 0;</code> be changed to <code>price = productField.val();</code> Will that work?</p> <p>I know hacking price.js probably isn't the best solution due to upgrades. Would anyone know if this function can be overridden through functions.php? </p> https://legacy.forums.gravityhelp.com/topic/dynamic-price-per-square-metre-calculation#post-16784 Fri, 21 Jan 2011 14:06:31 +0000 mrhoneyfoot 16784@https://legacy.forums.gravityhelp.com/ <p>David Smith, I salute you. Really appreciate it mate. Works beautifully. Quick question though.</p> <p>A problem with a user defined field is that the user can type over it. Tried hiding the price field with conditional logic, hoping Total Price would step into the breach. However Total Price doesn't pick up the price field when it's hidden. David is there a way to get Total Price to pick up the hidden field? Given that Total Price works through javascript too, is it possible to adapt your snippet? </p> https://legacy.forums.gravityhelp.com/topic/dynamic-price-per-square-metre-calculation#post-16714 Thu, 20 Jan 2011 15:25:33 +0000 David Smith 16714@https://legacy.forums.gravityhelp.com/ <p>Ok... so I got a little carried away here... and I have to throw out the disclaimer that we can't really offer this level of support on every forum request, but here is a really solid start on this. You piqued my interest. :P</p> <p><a href="http://pastie.org/1481851" rel="nofollow">http://pastie.org/1481851</a></p> <p>There are five pieces of this you'll need to update for your form (there are notes in the code itself):</p> <ol> <li>The ID specified by the hook</li> <li>Height Input</li> <li>Width Input</li> <li>Price Input</li> <li>Price Per Meter</li> </ol> <p>I used number fields for the height and width and a price field set to the "user defined price" option for the price field.

Essentially to calculate price per square metre. Is this possible with gravity forms? Or with PHPurchase and gravity forms? Or has anyone heard of a solution out there?</p> <p>Cheers Guys. </p>
