Multiform seems to be easier, so i changed to multiform:<br /> Examplepage: <a href="http://skintern.de/kunden/1-2/" rel="nofollow">http://skintern.de/kunden/1-2/</a> (Customer = Kunden)</p> <p>In functions.php i try something like that:<br /> <a href="http://pastie.org/2212213" rel="nofollow">http://pastie.org/2212213</a></p> <p>But i have no idea, how to post the result to kundenname (input name='input_36' id='input_2_36') </p> https://legacy.forums.gravityhelp.com/topic/validation-via-external-databasetable#post-29634 Mon, 11 Jul 2011 12:28:48 +0000 Carl Hancock 29634@https://legacy.forums.gravityhelp.com/ <p>This could only be done as a customization. You'd could use jQuery and AJAX so when the customer enters information in that field it executes jQuery, which then may execute some AJAX code. </p> <p>Another option would be to use a multi-page form and then use custom PHP to use the gform_validation hook. Have the customer number on the first page of the form, the gform_validation hook could then fire and validate the customer number and then pre-populate the appropriate fields.</p> <p>There is How To examples for both the gform_validation hook and dynamically populating fields in the How To section of the Documentation. </p> https://legacy.forums.gravityhelp.com/topic/validation-via-external-databasetable#post-29589 Mon, 11 Jul 2011 05:22:45 +0000 tca 29589@https://legacy.forums.gravityhelp.com/ <p>Hi there, </p> <p>is it possible to create a field e.g. "CustomerNumber" which is checking an external databasetable and outputs the customername from this one?</p> <p>External DB:<br /> CUSTOMERNUMBER | CUSTOMERNAME</p> <p>Gravity Form:<br /> Field "Customernumber" -&gt; AJAX read external DB and outputs the matching Customername</p> <p>Thank you </p>
