I am new to wordpress and am currently using WordPress Rest API to help automatically create custom posts using existing data. 1 of the fields needed is an array of image IDs so that images can be displayed. If a post is manually created on wordpress with the images, I know that the meta data would need to be in this format
"fave_property_images":["18339","18337","18321","17794","17793","17792","17791","17790","17789","17787"]
However, after posting through WordPress Rest API, the meta data automatically becomes serialized as such and no image is displayed.
"fave_property_images":["a:3:{i:0;s:5:\"18297\";i:1;s:5:\"18337\";i:2;s:5:\"17855\";}"]
Is there a way to prevent the auto serialization of my data?
Edited changed my getcallback function with reference from https://developer.wordpress.org/reference/functions/register_rest_field/
functions.php
function add_fave_property_images() {
register_rest_field('property',
'fave_property_images',
array(
'get_callback' => 'get_post_meta_for_api',
'update_callback' => 'rest_update_property_meta',
'schema' => array(
'type' => 'array',
'items' => array(
'type' => 'string',
),
),
)
);
}
function get_post_meta_for_api( $object ) {
//return the post meta
return get_post_meta( $object['id'], 'fave_property_images', false) ;
}
function rest_update_property_meta($value, $post, $field_name) {
// Update the field
return update_post_meta($post->ID, $field_name, $value);
}
I have also tried maybe_unserialize()
to no avail. I would appreciate any help thank you!
2nd Edit I am currently using postman to post just for testing purposes. This is a sample json that I am sending

3rd edit I have managed to display the array on fave_property_images
field, however the field in property_meta
remains a serialized array
And this is the resultant sample json from /wp-json/wp/v2/schools

However if I add images by editing the post on wordpress, the json would be as follows and the field fave_property_images
under property_meta
would just be an array.

get_post_meta_for_api()
function, both$post
and$field_name
are undefined. Also, the first parameter for the function is not an object and instead, it's an array. See the example here.fave_property_images
meta entries? If not, then you should callget_post_meta()
withtrue
being the third parameter.fave_property_images
, my sample post json is above. But i can assure you i have tried bothtrue
andfalse
parameters forget_most_meta()
and they both didnt work.
