drop down value different than content text

Hi guys,

Since I need to pass a country abbreviation (and not the country name) to a 3rd party script, I need to be able to modify the country values.
So instead of:
<option value='United States' >United States</option>
I need:
<option value='US' >United States</option>

Carl wrote 4 months ago: "Right now it is not possible to create a drop down with a value different than the content text. But we do plan on adding this feature in an upcoming release. "

Is it already possible? If not yet, how can I hack the values?

Thanks,
Erwin

That works like a charm.
Thanks (Dank je wel) Jan Egbert!

Cheers,

Sorry to say, but it didn't work :(

I have this to populate the drop down (this works)

add_filter( 'gform_pre_render_1', 'populate_dropdown' );
function populate_dropdown($form){
    $items = array();
    $items[] = array("text" => "Canada", "value" => "CA");
    $items[] = array("text" => "France", "value" => "FR");
    $items[] = array("text" => "Germany", "value" => "DE");
    $items[] = array("text" => "Netherlands", "value" => "NL");
    $items[] = array("text" => "United Kingdom", "value" => "GB");
    $items[] = array("text" => "United States", "value" => "US");

    foreach($form["fields"] as &$field)
        if($field["id"] == 6){
            $field["type"] = "select";
            $field["choices"] = $items;
        }
    return $form;
}

Now, to pre-select the drop down the following code SHOULD work, but it doesn't:

add_filter("gform_field_value_country", "populate_country");
function populate_country(){
$country_value = 'US'; // for testing purposes I hard-coded setting the value
return $country_value;
}

But what SHOULD NOT work, but did work is the following:

add_filter("gform_field_value_country", "populate_country");
function populate_country(){
$country_value = 'United States';  // for testing purposes I hard-coded setting the value
return $country_value;
}

Unfortunately I only have the real value (US, UK, NL, etc.) to select the correct one.

So here's what did work: I added the following after
$items[] = array("text" => "United States", "value" => "US");

foreach($items as &$country )
		if ($country["value"] == 'US' {
			$country = array("text" => $country["text"], "value" => $country["value"], "isSelected"=> true);
		}

Note: I'm not a PHP coder, I'm a code thief ;) so some copy-pasting and adding some common sense/logic takes me a long way. I did get the result I wanted BUT what I don't know is if the code will bring a heavy strain on the server or wreck my Gravity form in any way.

So can you please check if my code gets your OK?

Thanks,
Erwin

Hi Alex,

How do you mean 'technically you don't need the second loop to set the "isSelected" property. You can just set it along with the "text" and "value" when building the $items[] array'?
Wouldn't i need to check the country_id if it matches? Or do you mean that i could include the 'if' while filling the array, like this:
$items[] = array("text" => "Canada", "value" => "CA", if ($country["value"] == 'US') "isSelected"=> true);

Regarding the storage of the country in the database: it would be great if both the text and value of drop down could be accessed independently, like: {country(text):6}, {country(value):6} (just thinking out loud here ;) )

Thanks,
Erwin

Alex wrote you don't need the second loop to set the "isSelected" property, but you seem to do the same as I did two posts ago ;)
What's this different than the code that I came up with?

Thanks Jan, works like a charm!
