I don't understand how your snippet can change the content dynamically. So how does it work? </p> https://legacy.forums.gravityhelp.com/topic/allow-html-block-to-be-dynamically-populated#post-17300 Mon, 31 Jan 2011 08:39:41 +0000 mrhoneyfoot 17300@https://legacy.forums.gravityhelp.com/ <p>Thanks to Alex Cancado for the snippet. As I understand it, the code isolates the specific form ID and then field ID. Anyone got any idea about the next step? How you set out the rules for dynamically changing the content based on other form field selections, in other words?</p> <p>Take the examples in the explanation above for colour and style. If there are 10 colours and 20 styles, that's 200 combinations that we want the HTML block to display. </p> <p>Anyone know what you should use to achieve this, and how? </p> https://legacy.forums.gravityhelp.com/topic/allow-html-block-to-be-dynamically-populated#post-17224 Sat, 29 Jan 2011 08:06:13 +0000 Alex Cancado 17224@https://legacy.forums.gravityhelp.com/ <p>Yes, you can use the Pre-render hook to dynamically change the HTML block content.<br /> Here is a code snippet to point you in the right direction. Place it in your theme's function.php file.</p> <pre><code>add_filter(&quot;gform_pre_render&quot;, &quot;populate_dropdown&quot;); function populate_dropdown($form){ //only applies to form id 124. Replace 124 with your actual form id if($form[&quot;id&quot;] != 124) return $form; //Modifying field id 1. Replace 1 with your actual field id. You can get the field id by looking at the input name in the markup. foreach($form[&quot;fields&quot;] as &amp;$field) if($field[&quot;id&quot;] == 1){ $field[&quot;content&quot;] = &quot;My HTML block content&quot;; } return $form; }</code></pre> https://legacy.forums.gravityhelp.com/topic/allow-html-block-to-be-dynamically-populated#post-17221 Sat, 29 Jan 2011 05:04:25 +0000 mrhoneyfoot 17221@https://legacy.forums.gravityhelp.com/ <p>My goal is to show a different image inside a html block based on cross-checking two multiple choice fields. Let's say they're called style and colour. Is it possible to dynamically populate a html block field to achieve this?</p> <p>My only other solution is to create a different html block with it's own image for every possible combination of style/colour (hundreds) and show/hide them where necessary using conditional logic. It will probably work but feels a bit clunky from a back-end point of view. Is there a smarter way?</p> <p>Out. </p>
