It automatically checks to see if the requested index/key exists in the $_POST global before attempting to access that index/key to prevent undefined index notices. </p> https://legacy.forums.gravityhelp.com/topic/form-displays-calculation-results#post-33768 Mon, 29 Aug 2011 08:37:17 +0000 x2gravity 33768@https://legacy.forums.gravityhelp.com/ <p>Worked perfectly<br /> Thanks</p> <p>Can you tell me what rgpost does?<br /> Thanks again </p> https://legacy.forums.gravityhelp.com/topic/form-displays-calculation-results#post-33761 Mon, 29 Aug 2011 07:28:41 +0000 David Smith 33761@https://legacy.forums.gravityhelp.com/ <p>Hi x2gravity,</p> <p>Give this a shot:</p> <p><a href="http://pastie.org/2447989" rel="nofollow">http://pastie.org/2447989</a></p> <p>The issue was you were updating the $_POST after Gravity Forms has already processed the entry and retrieved all the values from the $_POST. By using the gform_pre_submission hook, we can add the $savings value to the "Savings" field $_POST before Gravity Forms processes the entry so the new value will be processed.</p> <p>You can access the saved value using the token; something like {Field Name:field_id} ~ {Savings:2}. You can get the actual token from the drop down on the confirmation message and add it anywhere in the message. </p> https://legacy.forums.gravityhelp.com/topic/form-displays-calculation-results#post-33753 Mon, 29 Aug 2011 05:36:31 +0000 x2gravity 33753@https://legacy.forums.gravityhelp.com/ <p>At the moment no value is returned. Thanks for the heads up regarding the use of "post_submission". What do you recommend I use?</p> <p>Yes I just want to use the number that the user submits, do some simple calculations based on that number and return the result to the user via the displayed confirmation message. I might not even save in the database as well. </p> https://legacy.forums.gravityhelp.com/topic/form-displays-calculation-results#post-33692 Sat, 27 Aug 2011 13:54:31 +0000 Chris Hajer 33692@https://legacy.forums.gravityhelp.com/ <p>What happens now when this runs? Does any value come back or is it always -100 or something?</p> <p>Also, I think you are going to run into problems because you are running this "post_submission" which is after the entry is created. So, you will not be able to insert this into input_2 since the entry is already created.</p> <p>Are you just trying to take a number they submit, and show them a savings of 100 in the confirmation text (not an email, just the displayed confirmation message)? </p> https://legacy.forums.gravityhelp.com/topic/form-displays-calculation-results#post-33631 Fri, 26 Aug 2011 08:12:16 +0000 x2gravity 33631@https://legacy.forums.gravityhelp.com/ <p>I have tried to use this example (<a href="http://www.gravityhelp.com/forums/topic/mathematics-to-gravity-forms" rel="nofollow">http://www.gravityhelp.com/forums/topic/mathematics-to-gravity-forms</a>) and create a form that basically does a small calculation but cannot get it to work.</p> <p>Here is my code<br /> <pre><code>[php] add_action(&quot;gform_post_submission_8&quot;, &quot;calculate_savings&quot;, 10, 2); function calculate_savings($entry, $form){ $savings = $entry[&#39;1&#39;] - 100; $_POST[&#39;input_2&#39;] = $savings; return $form; }</code></pre> <p>POST['input_2'] is a hidden field in the form which I then insert in the confirmation message for the user to see.</p> <p>$entry['1'] is basically a numeric field which I then use to calculate.</p> <p>Any help would be appreciated<br /> Thanks </p>
