I am trying to update a sub field in a custom rest api endpoint.
Structure of my acf is as follows:
"fields": [
{
"key": "field_5faa2483959b9",
"label": "field group",
"name": "field_group",
"type": "group",
"instructions": "",
"required": 0,
"conditional_logic": [
[
{
"field": "field_5faa23d8959b8",
"operator": "==",
"value": "content"
}
]
],
"wrapper": {
"width": "",
"class": "",
"id": ""
},
"layout": "block",
"sub_fields": [
{
"key": "field_5fadbecbfcc8a",
"label": "field_1",
"name": "field_1",
"type": "post_object",
"instructions": "",
"required": 0,
"conditional_logic": 0,
"wrapper": {
"width": "",
"class": "",
"id": ""
},
"post_type": [
"writer"
],
"taxonomy": "",
"allow_null": 0,
"multiple": 0,
"return_format": "id",
"ui": 1
},
{
"key": "field_5fa0795d696df",
"label": "field_2",
"name": "field_2",
"type": "text",
"instructions": "",
"required": 0,
"conditional_logic": 0,
"wrapper": {
"width": "",
"class": "",
"id": ""
},
"default_value": "",
"placeholder": "",
"prepend": "",
"append": "",
"maxlength": ""
}
]
This is the callback I am running on the endpoint:
function assign_subfield_val( $request ) {
$parameters = $request->get_params();
$project = $parameters['project']; //number
$writer = $parameters['writer']; //number
if($writer != '' && $project != ''){
update_sub_field(array('field_5faa2483959b9', 1, 'field_5fadbecbfcc8a'), $writer, 2527);
return gettype($project);
}else{
return $parameters;
}
}
I have use update_field and update_sub_field, used both names and IDs, nothing is working.
If I try to update a top-level field this way it works, but having issues with the sub field. Please help!
