basically, want if field empty, either ignored or not submitted or skipped.
thanks!
if (!empty($_post)) checks see if post array contains data @ all, means every insert statement trigger, if there one field set in post array. instead, need check each individual field see if set, , if has value you're interested in (ie, not empty string). or in other words:
change if (!empty($_post)) { if(isset($_post['username']) && $_post['username'] != '') {
for each of insert statements, , appropriate $_post key (username, description, etc)
for completeness
apparently, empty($_post['username']) work, opposed isset , subsequent check. comments
