However, my query fails with the following message, "Query Failed". Actually I have printed this message whenever the query fails but I am having hard time looking for the reason behind this failure. Unfortunately, I couldn't find it http://stackoverflow.com/questions/12227626/how-to-display-mysql-error-in-php because the error is not specified on the web page. My question is, is there any way to display the error message that caused the failure on the web page. Thank you. Here's my code, $from= "Findings"; $where=""; if($service!= null) { $from = $from . ", ServiceType_Lookup"; $where= "Findings.ServiceType_ID= ServiceType_Lookup.ServiceType_ID AND ServiceType_Name= ". $service; if($keyword!= null) $where= $where . " AND "; } if( $keyword != null) { $where= $where . "Finding_ID LIKE '%$keyword%' OR ServiceType_ID LIKE '%$keyword%' OR Title LIKE '%$keyword%' OR RootCause_ID LIKE '%$keyword%' OR RiskRating_ID LIKE '%$keyword%' OR Impact_ID LIKE '%$keyword%' OR Efforts_ID LIKE '%$keyword%' OR Likelihood_ID LIKE '%$keyword%' OR Finding LIKE '%$keyword%' OR Implication LIKE '%$keyword%' OR Recommendation LIKE '%$keyword%' OR Report_ID LIKE '%$keyword%'"; } $query = "SELECT Finding_ID, ServiceType_ID, Title, RootCause_ID, RiskRating_ID, Impact_ID, Efforts_ID, Likelihood_ID, Finding, Implication, Recommendation, Report_ID FROM ".$from .

I know there is mysql error msg something wrong, because when I write or die("ERROR"); It displays ERROR. So the problem must be with that line of code. When I write or die(mysql_error()); It shows up blank. Here is my code for the line that I think has the error: while ($rows = mysql_fetch_array($sql6) or die(mysql_error())) { Now here is the full code block: $sql6 = mysql_query("SELECT * FROM replies WHERE thread_id = $thread_id"); $numRows = mysql_num_rows($sql6); $replies = ''; if ($numRows < 1) { $replies = "There are no replies yet, you can make the first!"; } else { while ($rows = mysql_fetch_array($sql6) or die(mysql_error())) { $reply_content = $rows['5']; $reply_username = $rows['7']; $reply_date = $rows['8']; $reply_author_id = $rows['4']; $sql9 = mysql_query("SELECT * FROM users WHERE id = '$reply_author_id'"); $numRows = mysql_num_rows($sql9); if ($numRows < 1) { while ($rows = mysql_fetch_array($sql9)) { $reply_user_fn = $rows['first_name']; $reply_user_ln = $rows['last_name']; $reply_user_id = $rows['id']; $reply_user_pp = $rows['profile_pic']; $reply_user_lvl = $rows['user_level']; $reply_user_threads = $rows['threads'];Die(mysql_error())
