Wordpress get terms of specific category of each post and display it

What I want to do is get the terms of a specific category of each post and then display it in this post.

Should be simple that the code that I have written: 

function wodarchive_entry($post_id = null) {

  $post = get_post( $post_id );
  $termsArray = get_the_terms( $post->ID, "category" );
  //Get the terms for this particular item
  $termsString = ""; //initialize the string that will contain the terms

  foreach ( $termsArray as $term ) { // for each term 
    $termsString .= $term->name.' ';
    $category_id = $term->parent;//create a string that has all the slugs 
    if($category_id == '203'){
       echo $termsString;
    }
  }             
}

Btw, this is not working. Well, almost. It is giving me also values of other categories, probably because the if statement plays until finds the condition.

If you only want to get the matching terms in $termsString you should place the assignment inside the if-loop.

function wodarchive_entry($post_id = null) {
  $termsArray = get_the_terms( $post_id, "category" );
  //Get the terms for this particular item
  $termsString = ""; //initialize the string that will contain the terms

  foreach ( $termsArray as $term ) { // for each term 
    $category_id = $term->parent;//create a string that has all the slugs 
    if($category_id == '203'){
       $termsString .= $term->name.' ';
    }
  }
  echo $termsString;                
}
