json_encode()

 / Published in: PHP
 

I can\\'t this function to fire WordPress shortcodes or getmetadata:\r\n\r\nProblem 1. In the shortcode, if I remove \\'.$item.\\' and replace with it\\'s regular value that the post_meta holds (hard code it) this works just fine. Also the same with the $numb variable.\r\n\r\nHave any ideas why these variable aren\\'t working before they\\'re encoded?

  1. function discount() {
  2. 	global $post;
  3.  
  4. 	$item = get_post_meta( $post->ID, 'item_number_discount', true );
  5. 	$numb = str_replace( 'theme-', '', $item );	
  6.  
  7. 	$arr = array();
  8. 	$entry['code'] = "success";
  9. 	$entry['link'] = '<a class="purchase discount" href="javascript:{}" onclick="document.getElementById(\'cartButtonForm_'. $numb .'\').submit(); return false;">Purchase discount</a>';
  10. 	$entry['form'] = do_shortcode( '[cart-button item="'.$item.'" showprice="no" ]' );
  11.  
  12. 	$arr[] = $entry;
  13. 	header("Content-Type: application/json");
  14. 	echo json_encode($arr);
  15. 	exit();
  16.  
  17. }
  18. add_action( 'wp_ajax_add_discount', 'discount' ); //hook to ajax action
  19. add_action( 'wp_ajax_nopriv_add_discount', 'discount' ); //hook to ajax action
