Dynamic checkboxes

    Hi,

    i tried the following example:
    http://www.gravityhelp.com/forums/topic/dynamic-checkboxes (Posting 2)

    and it nearly works. My problem is that only the first value is returning. If i edit the field and put some empty "value rows" in, then there are more checkbox-values returning. But my problem is, that i don't know how much empty value rows i have to put in because i don't know how much values the database returns.

    Can you paste your code here so I can take a look at it? And do you have a URL you can include to the example form you are trying to build?

    that is the ulr for the form

    the code:

    function ess_cat($form){
        foreach($form['fields'] as &$field){
            if(strpos($field['cssClass'], 'preise') === false)
                continue;
            $categories= get_categories(array('child_of'=>'15','hide_empty'=>0));
            $choices = array();
    		$i=0;
            foreach($categories as $category){
                $choices[$i]['text'] = $category->name;
    			$choices[$i]['value'] = $category->slug;
    			$i++;
            }
    
            $inputs = array();
    		$i=0;
            foreach($categories as $category){
                $inputs[$i]['label'] = $category->slug;
    			$inputs[$i]['id'] = "7".$i;
    			//7 ist die Field Id
    			$i++;
            }		
    
    		$field["inputs"] = $inputs;
            $field['choices'] = $choices;
        }
        return $form;
    }

    i have to extended the value part with many empty rows

    I don't think you should wrap everything you are doing in a foreach because each subsequent nested foreach will be run multiple times, thus creating your issue with the arrays of values you are then trying to pass back to the fields.

  5. You shouldn't have to add any checkbox items to your checkbox field in the form editor in order to dynamically populate it using the code example you are using. It replaces the values entirely, the existing values don't act as placeholders.

    I just tested the example you are working from and implemented it on my own test site and it works fine. The example I am referring to is here:

    http://www.gravityhelp.com/forums/topic/dynamic-checkboxes#post-9476

    I implemented this code, exactly as is, on my test site and had no problem using it to dynamically populate the checkbox field. I am including screenshots of what I have done below.

    I created a new form and on that form I placed a Checkbox field that I want to dynamically populate. The field consists of only 1 choice, but it doesn't matter as all the choices will be replaced by my custom code. See this screenshot:

    http://dl.dropbox.com/u/185347/Slingshot/Pictures/Screen%20Shot%202012-04-30%20at%2011.36.52%20AM.png

    After creating the form with the checkbox I then implemented the example code to populate that field dynamically using the gform_pre_render hook by placing custom code in my themes functions.php file. See this screenshot:

    http://dl.dropbox.com/u/185347/Slingshot/Pictures/Screen%20Shot%202012-04-30%20at%2011.37.48%20AM.png

    Now when I preview my form, the checkbox field is dynamically populated with the items it's being populated with in the custom code that I implemented as opposed to the choices in the form editor itself. See this screenshot:

    http://dl.dropbox.com/u/185347/Slingshot/Pictures/Screen%20Shot%202012-04-30%20at%2011.38.25%20AM.png

    So the example code does indeed work. If it's not working in your implementation that means that it wasn't implemented properly or the custom code related to getting and returning the values you want to populate the field is not functioning correctly.

    I would start again from the beginning and implement the code exactly as it is found here:

    http://www.gravityhelp.com/forums/topic/dynamic-checkboxes#post-9476

    Then update it to suit your needs. The issue is happening on your end with how you are populating the array of choices and inputs. It sounds like if it's only passing the first value, that you aren't actually passing an array of values like you should be.

    Hi Carl, my output is okay too. But please try to choice the second Checkbox and look then into your database. I tried several times an the second (third, and so on) checkbox isn't publish to database (the visiual output is okay)

    So what is output to the database? When you do view source and look at the code being output for the list, what are the values associated with the choices?

  8. I do see what you are referring to. I am going to take a deeper look and see what is going on. I'll reply back shortly.
