Please verify my code :)

I have placed the following in the WP-ADMIN/POST.PHP file, just after line 145. The idea is to capture the post_ID, find out if there’s already text in Forum_Link field of that post, if not, run another query to another database (the insert_post function, that returns a value), then place that Returned Value into the Forum_Link field I added to the wp_post Table.

Don’t worry about the Insert_Post function, just pretend it returns “a value”. 🙂

Are there any glaring errors to be seen? I’m an extreme newbie, but like to think I’m very adaptable. Thank you for any comments/questions. Feel free to message me at middae !at hotmail -Dot- com for any add’l info.
/*Custom Coding for adding Forum Link to post*/
//grab $post_ID from WP procedures
$cstPostQuery = “SELECT forum_link FROM $wpdb->posts WHERE ID = $post_ID”;
$cstMKBH_result = “”;
$cstMKBH_result = $wpdb->query($cstPostQuery);
if $cstMKBH_result = “” {
$cstMKBH_WPpostID = $post_ID;
//insert Forum Topic with Post Info, may need to change $content string.
$cstMKBH_retval = $insert_post($content,$post_title, 1, 1, ‘baldeagle152′,’User attach Sig here’);
//add the Topic_ID and post_ID to the forum_link field in WP_POSTS
$cstPostQuery =”UPDATE $wpdb->posts SET forum_link = $cstMKBH_retval WHERE ID = $cstMKBH_WPpostID”;
$cstMKBH_result = “”;
$cstMKBH_result = $wpdb->query($cstPostQuery);
