If you want to populate a text area with just the value of that parameter in the query string, all you need to do is on the advanced tab of your form field, check the box "Allow field to be populated dynamically" then fill in the "parameter name" with "o" (no quotes) then use the URL as you have shown it, and the value of "o" will be placed in the value for the text area.</p> <p>Do either of those solutions help you?</p> <p>Here is more information about how you can pre-populate fields:<br /> <a href="http://www.gravityhelp.com/documentation/page/Using_Dynamic_Population" rel="nofollow">http://www.gravityhelp.com/documentation/page/Using_Dynamic_Population</a> </p> https://legacy.forums.gravityhelp.com/topic/complete-a-field-with-a-variable-value#post-46108 Wed, 11 Jan 2012 07:08:48 +0000 spiral 46108@https://legacy.forums.gravityhelp.com/ <p>I have a form with a textarea field and I would like to complete the textarea value with a variable, is it possible to do it with GF?</p> <p>In this case I will access the form with a URL like these: <a href="http://www.myweb.com/realizar-pedidos/?o=22" rel="nofollow">http://www.myweb.com/realizar-pedidos/?o=22</a><br /> Then, on my page I will request the o variable ($my_var = $_GET['o']) and then I would like to fill my textarea field with $my_var value.</p> <p>Thanks! </p>
