[Plugin: JSON API] Creating post with a value for its custom_field

in the post.php file there is the function save($values = null). simply add the following code to the end of this file

foreach($values as $key => $value){
if(strlen(strstr($key,’id’))==0 &&
strlen(strstr($key,’type’))==0 &&
strlen(strstr($key,’status’))==0 &&
strlen(strstr($key,’title’))==0 &&
strlen(strstr($key,’content’))==0 &&
strlen(strstr($key,’author’))==0 &&
strlen(strstr($key,’categories’))==0 &&
strlen(strstr($key,’tags’))==0)//it must be a custom_field, so add it
update_post_meta($this->id,$key,$value);
}

$wp_post = get_post($this->id);
$this->import_wp_object($wp_post);

return $this->id;
}

after that you should be able to create a post with custom values.
According to your example simply call
https://localhost/public_html/website/?json=posts/create_post&dev=1&nonce=eaa7969ea5&categories=competitions,photos&title=hello%20world%204&content=”mycontent”&competition=summer&status=publish

to add the value “summer” to your field competition

Amazing! This is exactly what I needed thanks cohen!

Hello.

I solved this by adding the following in post.php in the save function:

// add custom fields
  if ( !empty($values["custom"]) ) {
    	foreach ($values["custom"] as $metakey => $metavalue) {
    		update_post_meta($this->id,$metakey,$metavalue);
    	}
 }

The query:

https://localhost/site/?json=posts/create_post&dev=1&nonce=xxx&title=Post%20title&status=publish&custom[custom_field_1]=value1&custom[custom_field_2]=value2

Query for listing the fields in the response:

https://localhost/site/?json=posts/create_post&dev=1&nonce=xxx&title=Post%20title&status=publish&custom[custom_field_1]=value1&custom[custom_field_2]=value2&custom_fields=custom_field_1,custom_field_2
