Happy to hear you got this working. </p> https://legacy.forums.gravityhelp.com/topic/gform_pre_render-are-post-variables-available#post-46501 Mon, 16 Jan 2012 17:08:51 +0000 dochara 46501@https://legacy.forums.gravityhelp.com/ <p>I got around it another way. I just made the field required, and the unset it if it was not needed. It was my bad function and not the absence of post data that was complicating things. :)</p> <p>In case it helps anyone else, this is what I was trying to do and what worked.</p> <p>Some products on this site require that the person purchasing declares that they have insurance. It should be clear what's happening here from that.</p> <pre><code>function sd_hide_or_require_insured($form){ $insuredfield = array(&#39;Insured&#39;); global $post; $needsinsurance = get_post_meta($post-&gt;ID,&#39;_sd_prod_insurance&#39;,true); if ($needsinsurance==0) { foreach($form[&#39;fields&#39;] as $key=&gt;$field) { if(in_array($field[&#39;label&#39;], $insuredfield)) { unset($form[&#39;fields&#39;][$key]); } } } return $form; }</code></pre> https://legacy.forums.gravityhelp.com/topic/gform_pre_render-are-post-variables-available#post-46490 Mon, 16 Jan 2012 15:56:47 +0000 David Smith 46490@https://legacy.forums.gravityhelp.com/ <p>Assuming you are displaying your Gravity Form on a post/page, the <strong>$post</strong> global should be available. Could you share the specific code you are using and perhaps a link to the page? </p> https://legacy.forums.gravityhelp.com/topic/gform_pre_render-are-post-variables-available#post-46474 Mon, 16 Jan 2012 11:58:29 +0000 dochara 46474@https://legacy.forums.gravityhelp.com/ <p>I've searched for this, and made several attempts to resolve it without sucess.</p> <p>Essentially, I am using a single form and populating fields dynamically with post meta from the post where the form is embedded. That's working fine.</p> <p>However there is one field I want to appear ONLY when a certain post meta value is set.</p> <p>I tried to use gform_pre_render to achieve this, but I am realising that post parameters (I used $global posts; in my function) are unavailable. Is this the case? If so, is there any later point at which a field could be unset if it's not needed?</p> <p>Thank you. </p>
