Hi Guys,
I'm trying to us the "gform_pre_render" filter to create a dropdown list for a product using the paypal addon.
If I use the filter, my option list displays correctly, but the paypal add-on no longer works.
Am I using the wrong filter to accomplish this?
Thanks
What exactly does not work? Does it trigger a validation error?
There aren't any errors at all. If I override the dropdown (which works fine), it seems to ignore that the form is associated with paypal, and the form will submit like a normal form.
Here is the function that I'm using....
add_filter('gform_pre_render_5', 'custom_event_tickets');
function custom_event_tickets($form_meta) {
global $sp_ecp;
$formId = $form_meta['id'];
$options = sp_get_events('100');
//print_r_html ($form_meta);
//Creating drop down item array.
$items = array();
//Adding initial blank value.
$items[] = array("text" => "Choose...", "value" => "Choose...", "isSelected" => "1", "price"=>'$0.00');
//Adding Available Events and prices to the items array
foreach ( $options as $option )
{
$cost = sp_get_cost($option->ID);
if ($cost == "Free") $cost = "$0";
$items[] = array("value" => $option->post_title . '... ' .$cost, "text" => $option->post_title . '... ' .$cost, "isSelected" => "", "price" => $cost . ".00" );
}
foreach($form_meta["fields"] as &$field) {
if($field["id"] == 1)
{
$field["type"] = "select";
$field["choices"] = $items;
}
}
//print_r_html ($form_meta);
return $form_meta;
}my choices array looks like this before I make the change (this works fine):
[choices] => Array
(
[0] => Array
(
[text] =>First Choice
[value] => First Choice
[isSelected] => 1
[price] => $10.00
)
[1] => Array
(
[text] => Second Choice
[value] => Second Choice
[isSelected] =>
[price] =>$12.00
)
[2] => Array
(
[text] => Third Choice
[value] => Third Choice
[isSelected] =>
[price] => $15.00
)
)I made sure that my dynamic array showed the same info, the same way, which looks like this:
[choices] => Array
(
[0] => Array
(
[text] => Choose...
[value] => Choose...
[isSelected] => 1
[price] => $0.00
)
[1] => Array
(
[value] => Nathan Angelo... $10
[text] => Nathan Angelo... $10
[isSelected] =>
[price] => $10.00
)
[2] => Array
(
[value] => Marvin & Leanda King... $0
[text] => Marvin & Leanda King... $0
[isSelected] =>
[price] => $0.00
)
[3] => Array
(
[value] => Parachute Musical / Mike Mains... $10
[text] => Parachute Musical / Mike Mains... $10
[isSelected] =>
[price] => $10.00
)I might easily be overlooking something. I appreciate the help.
It looks like this is an oversight from my part. When determining the fields to be sent to PayPal, a fresh version of the form meta is used without getting run through the gform_pre_render filter. Your new choices are probably getting save as an entry, but the PayPal add-on thinks there aren't any products selected and bypasses the PayPal checkout.
I will take a deeper look into this and see what I can do to fix it.
Meanwhile, you can use the gform_paypal_query (http://www.gravityhelp.com/documentation/page/Gform_paypal_query) to manually add your drop down values to the PayPal query. You may need to add a dummy value to your drop down so that the PayPal checkout does not get bypassed.
Very cool... thank you! It worked, and all I had to do was use the "gform_paypal_query" filter to update the default query string.
add_filter('gform_paypal_query_5', 'update_paypal_query');
function update_paypal_query($query_string) {
return $query_string;
}The js for the total field still does not update based on selection ( the js doesn't get called ), but I should hopefully be able to figure that out.
Thanks again for the help
Great! I am glad that worked for you. Is your drop down a product field or a regular drop down field? The Total calculation should get called if you are using a product field. If you don't figure it out, send a link to your form and I will take a look.
Thank you so much for your help... That was exactly my issue. My $field loop was incorrect, adding the type as "product" and the inputType as "select" fixed all the issues I was having. There is no longer the need to us the gform_paypal_query filter.
I'll paste the code, just in case this helps anyone else in the future.
foreach($form_meta["fields"] as &$field) {
if($field["id"] == 1)
{
$field["type"] = "product";
$field["inputType"] = "select";
$field["choices"] = $items;
//$field["enablePrice"] = 1;
//$field["basePrice"] = '$0.00';
}
}Thanks again!!!
