mac_gyver Posted November 15, 2013 Share Posted November 15, 2013 the code you have posted is not running the sql query statement at all, nor is it fetching and using the data from the query statement, so just exactly how did you expect your code to produce the expected output?

Barand Posted November 15, 2013 Share Posted November 15, 2013 (edited) mysql_query mysql_fetch_assoc mysql_fetch_row or, better, use the mysqli_ versions as mysql_ functions are deprecated Edited November 15, 2013 by Barand Quote Link to comment Share on other sites More sharing options...

Solution Barand Posted November 16, 2013 Solution Share Posted November 16, 2013 put in some checks $sql = "SELECT $dim FROM $tbl_name WHERE username='$myusername' and password='$mypassword'"; $takevalue=mysql_query($sql); // check for errors in query if (!$takevalue) { echo "$sql<br>" . mysql_error(); } else { // check if any records found if (mysql_num_rows($takevalue)==0) { echo "No matching records<br>"; } else { $array = mysql_fetch_array($takevalue); $mid=$array['MID']; echo $mid.'<br/>'; } } Quote Link to comment Share on other sites More sharing options...
