I've noted in the code what will need to be changed to update this for your setup.</p> <p><a href="http://pastie.org/1579958" rel="nofollow">http://pastie.org/1579958</a> </p> https://legacy.forums.gravityhelp.com/topic/verify-if-email-is-duplicate-before-submitting-the-form#post-18903 Fri, 18 Feb 2011 10:05:25 +0000 giorgiogu 18903@https://legacy.forums.gravityhelp.com/ <p>Hi Carl,</p> <p>Sorry again :(</p> <p>I'm trying to understand the function but can't get much out of it.</p> <p>My first issue is how to get the user email from wordpress?

There isn't a way to access it yourself from the forms_model code. You'd have to duplicate that function and repurpose it for your needs. </p> https://legacy.forums.gravityhelp.com/topic/verify-if-email-is-duplicate-before-submitting-the-form#post-18559 Tue, 15 Feb 2011 01:29:14 +0000 giorgiogu 18559@https://legacy.forums.gravityhelp.com/ <p>Thanks David, i'm going to have a look at it, is there any way to make that function visiable insidede the page i want to call it? do i need to create an hook in my page theme template?</p> <p>thanks Giorgio </p> https://legacy.forums.gravityhelp.com/topic/verify-if-email-is-duplicate-before-submitting-the-form#post-17483 Wed, 02 Feb 2011 14:05:34 +0000 David Smith 17483@https://legacy.forums.gravityhelp.com/ <p>You can theoretically use the same function that Gravity Forms uses to test for duplicate entry values. It's called <strong>is_duplicate()</strong> and you can find it in forms_model.php on line 1594. </p> https://legacy.forums.gravityhelp.com/topic/verify-if-email-is-duplicate-before-submitting-the-form#post-17446 Tue, 01 Feb 2011 20:23:43 +0000 giorgiogu 17446@https://legacy.forums.gravityhelp.com/ <p>Hello, </p> <p>From this page:</p> <p><a href="http://gm-studio.co.uk/model-contest/photo-contest/" rel="nofollow">http://gm-studio.co.uk/model-contest/photo-contest/</a></p> <p>if the user is logged in, there is a link to go to this page:</p> <p><a href="http://gm-studio.co.uk/model-contest/upload-your-pictures/" rel="nofollow">http://gm-studio.co.uk/model-contest/upload-your-pictures/</a></p> <p>Where (if the user is logged in) is possible to fill a form where the email field have to be unique, this is working well.</p> <p>I would like to know if there is a simple php code to add in the first page able to verify if there is already an entry in the database submitted bu the logged user, in that case the link to the form page doesn't appear?</p> <p>I have already added the php to verify if the user is logged in, but i don't know how verify that his email is already in one entry in the database.</p> <p>Thanks for your help</p> <p>Giorgio </p>
