Dynamic Creating Conditional Logic

  1. I've created a drop list and populated it dynamically using it's Choices from a set of data we hold in our database. I have a couple of fields that I want to hide or show based on the drop down list values so I need to dynamically create conditional logic for this. Can you post a example of this in action please. I've used the conditional logic before using the form designer, but now i need to create that myself within the form.

  2. I worked it out and put it in a generic function to use.

    $rules = array();
    for($i = 0; $i<count($showarray); $i++)
    $value = $showarray[$i];
    $rules[] = array('fieldId' => $fieldid, 'operator' => 'is', 'value'=>$value);
    $field['conditionalLogic'] = array('actionType' => 'show','logicType' => 'any','rules' => $rules);

    Pretty basic, the $showarray holds an array of text items that the 'fieldId' ($fieldid) can be to show the field. I have written a similar function to hide as well, but I think there is an issue with GravityForms. I set the $field up with the property of being required and I expected this to be ignored when the field was hidden just as when you add conditional logic using the UI. However when I add the conditional logic dynamically as above the fields are hidden as expected but when the form is submitted it can't be because a hidden field from the conditional logic is halting the operation because of the required property of it.

    If this a bug, or is there another way of setting the conditional logic dynamically on required fields so it works correctly?

    Hi Ben.

    This is exactly what i am looking for.
    I´m a php and sql beginner, so is it possible for you to show me what you have done to achieve this - like how do the code you put in the function.php look like.
