Using the sample code gets you started but its only really base64encoded. Searching around I came across this article - <a href="http://ideone.com/yQIAX" rel="nofollow">http://ideone.com/yQIAX</a> which used "mcrypt". </p> <p>So basically pop this code in - instead of the base64_encode... (note) you'll need the mcrypt extension for php enabled. </p> https://legacy.forums.gravityhelp.com/topic/need-help-on-how-to-use-gform_save_field_value#post-66618 Tue, 17 Jul 2012 04:52:31 +0000 ax10 66618@https://legacy.forums.gravityhelp.com/ <p>Hi Chris,<br /> Ok head is clearer this morning, I understand the '10,4' args in add_filter() now thanks. </p> <p>Also I'd blindly copied the code in the docs for gform_get_input_value example and there is an error in that the add_filter() is referencing a function called 'decode_field' but in sample code its called 'decrypt_field'... which gave me odd results. <a href="http://www.gravityhelp.com/documentation/page/Gform_get_input_value" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_get_input_value</a></p> <p>Ok with that out of the way; I presume that if I just (as per sample code)<br /> <pre><code>return base64_encode($value)</code></pre> <p>and<br /> <pre><code>return base64_decode($value)</code></pre> <p>in their respective functions every GF form and every field will get encoded/decoded right?</p> <p>Q1. Is this safe to use as is for advanced fields (name, address) and checkboxs/radio buttons? Do these need to be treated any differently?</p> <p>Q2.

Basically I'm trying to understand how to use the gform_save_field_value() and gform_get_input_value() filters to<br /> a) encode/encrypt an entire form or<br /> b) just a particular field in a form.</p> <p>In the docs - what is 10, 4? I thought it was in relation to the field and form ids?<br /> <pre><code>&lt;?php</code></pre> <pre><code>add_filter(&quot;gform_save_field_value&quot;, &quot;save_field_value&quot;, 10, 4);</code></pre> <pre><code>function save_field_value($value, $lead, $field, $form){</code></pre> <pre><code>return base64_encode($value);</code></pre> <p>}<br /> <pre><code></code></pre> <pre><code>add_filter(&quot;gform_get_input_value&quot;, &quot;decode_field&quot;, 10, 4);</code></pre> <pre><code>function decrypt_field($value, $lead, $field, $input_id){</code></pre> <pre><code>return base64_decode($value);</code></pre> <pre><code>}</code></pre> ?&gt;</p> <p>My form is at <a href="http://tinyurl.com/bvrcqh5" rel="nofollow">http://tinyurl.com/bvrcqh5</a></p> <p>My form ID is 2, and the 'Telephone' field is field ID 4. </p> <p>Thanks<br /> ax10 </p>
