# Using update_post_meta inside of a function

 * I can’t seem to figure this one out. As a test, i’m using a single post ID, custom
   field key, and a value. Every time I use update_post_meta inside of a function
   it doesn’t work. If I use update_post_meta outside of a function it works fine.
 *     ```
       function article_init(){
       	update_post_meta( 10123, 'phone-number', '8885551234');
       }
       ```
   
 * My ultimate goal is to populate those three args using variables instead of constants.
   Which is the reason I’m trying to use this inside of a function. Any idea why
   this isn’t working for me?
 * Thanks,
    IYBITWC

 * How and where are you calling the article_init() function?

 * I have a class that has the function in it. Here is a shortened example.
 * **Setup:**
 *     ```
       class PostArticle {
   
       	public function article_init(){
       		update_post_meta( 10123, 'phone-number', '8885551234');
       	}
   
       }
       ```
   
 * **Use:**
 *     ```
       $Article = new PostArticle;
       $Article->article_init();
       ```

 * Seems I didn’t ask the right question, the code I provided appears to work fine.
