Hello there,

I added a new field using gform_field_input. This field output a facebook LIKE box.

Everything works fine until the validation.

The LIKE box disappear and I would like it to stay on the page.

Could you please advice me on how I could fix this problem ?

Here is my code for adding the new field :

add_action("gform_field_input", "facebooklike_input", 10, 5);

function facebooklike_input($input, $field, $value, $lead_id, $form_id){

if($field["type"] == "facebook-like"){

$input = '';

if (sfc_is_fan()) { // Function developed by Simple Facebook Connect by Otto.

$input .= 'You LIKE us on Facebook, your chances are doubled.';

} else {

$input .= 'To double your chance to win, LIKE us on Facebook.';

}

}

return $input;

}

add_filter("gform_add_field_buttons", "add_facebooklike_field");

function add_facebooklike_field($field_groups){

foreach($field_groups as $group){

if($group["name"] == "advanced_fields"){

$group["fields"][] = array("class"=>"button", "value" => "Facebook Like it !", "onclick" => "StartAddField('facebook-like');");

break;

}

}

return $field_groups;

}

There was a small problem with your code when displaying the button in the admin. Following is the code with the fix:

As far as the field disappearing after validation, I could not replicate it. Following is a screenshot of my form after failing validation. Note the text from your field is still there.

Did I misunderstand the issue?

Hi Alex,

Thanks for your answer !

In fact, my custom field will display a Facebook Like Box like here :

http://www.tkwk.be/client/acea/www/contest-of-the-month/

My code for the custom field : http://pastie.org/2871065

The only problem is that after validation it seems that the Facebook Like Box which was containing an iFrame is now empty... I would like to understand why and find a way of fixing this issue.

Your support is much appreciated.

Cheers.

Update :

When I use HTML5 / JS integration it doesn't work :

[php]
$input = '<div class="fb-like-box" data-href="http://www.facebook.com/pages/Our-Future-Mobility-Now/172720562818982" data-width="292" data-height="150" data-show-faces="false" data-stream="false" data-header="false"></div>';

But when I use pure iframe the validation process does not remove the like box :

[php]
$input = '<iframe src="//www.facebook.com/plugins/likebox.php?href=http://www.facebook.com/pages/Our-Future-Mobility-Now/172720562818982&width=292&height=62&colorscheme=light&show_faces=false&border_color&stream=false&header=false&appId=215129495225503" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:292px; height:62px;" allowTransparency="true"></iframe>';

Any idea why ?

Thanks again for the support.

It looks like the problem is related to AJAX being enabled in your form. When AJAX is enabled, some scripts may need to be re-initialized when the page is submitted. The HTML5/javascript integration probably falls under that scenario.
What I recommend you do is simply disable AJAX for your form.

Hi Alex,

Me again ! Thanks again for the Pastie, it really helped me out.

I have still a question regarding this :

In the original pastie (http://pastie.org/2906268) the first $input variable is empty !

I can click my button "Facebook Like It !" in the admin and the custom field is displayed.

If I change the value of my $input into something like this : http://pastie.org/2906281

The button "Facebook Like It !" in the admin doesn't work anymore.

Do you have any idea why ?

If I need to use it, I have to add the field with the value $input = ''; in my code then change the value of $input once the field is already into the form.

Thanks again for your time and patience.

J.
