Problem:
Add a hidden honeypot "timer" field into CRED form
Solution:
Use CRED filter hook cred_form_validate to add such a custom validation, for example:
1) Add below codes into your theme/functions.php:

function loadtime_func($atts, $content) {
return time();
}
add_shortcode('loadtime', 'loadtime_func');

add_filter('cred_form_validate','honeypot_func',10,2);
function honeypot_func($field_data, $form_data)
{
list($fields,$errors)=$field_data;

if ($form_data['id']==123)
{
$loadtime = $_POST["loadtime"];
$totaltime = time() - $loadtime;

if($totaltime < 7) { $errors['loadtime'] = 'Please fill in the form before submitting!'; } } //return result return array($fields,$errors); }

Please replace 123 with the CRED form ID
2) modify your CRED form, add a hidden generic field:

[cred_generic_field field="loadtime" type="hidden" class="" urlparam=""]
{
"required":0,
"validate_format":0,
"persist":0,
"default":[loadtime]
}
[/cred_generic_field]

Problem:
One wordpress user can create one custom post with CRED form

Solution:
I suggest you try this:
Create a view to list posts created by current user,
a) if there is posts found, then display the link for CRED form edit post
b) if there isn't any post found, then display the CRED form for create new post.
