mrt003003 Posted May 9, 2011 Share Posted May 9, 2011 Hi there i have an array that catches all appropriate records from my database and selects a random row which is then outputted as a hyperlink. $colname_Class3 = "3"; $colname_Ships3 = "-1"; if (isset($_SESSION['MM_Username'])) { $colname_Ships3 = (get_magic_quotes_gpc()) ? $_SESSION['MM_Username'] : addslashes($_SESSION['MM_Username']); } mysql_select_db($database_swb, $swb); $query_Ships3 = sprintf("SELECT * FROM ships WHERE PlayerName = %s AND Class=%s AND Template='1'", GetSQLValueString($colname_Ships3, "text"), GetSQLValueString($colname_Class3, "int")); $Ships3 = mysql_query($query_Ships3, $swb) or die(mysql_error()); $totalRows_Ships3 = mysql_num_rows($Ships3); $count = 0; while ($row = mysql_fetch_assoc($Ships3)){ $array[$count]['ShipID'] = $row['ShipID']; $array[$count]['ShipName'] = $row['ShipName']; $array[$count]['Class'] = $row['Class']; $count++; } $total3 = count($array3); $random3 = rand(0,$total3 - 1); $random_ship3 = $array3[$random3]; $ShipID3 = $random_ship3['ShipID']; $url3 = '<a href="add_ship.php?recordID='.$ShipID3.'">Test3</a>'; echo '<span style="color: #009900">'; echo $url3;} This all worked fine until i added another similar query: $colname_Class4 = "4"; $colname_Ships4 = "-1"; if (isset($_SESSION['MM_Username'])) { $colname_Ships4 = (get_magic_quotes_gpc()) ? $_SESSION['MM_Username'] : addslashes($_SESSION['MM_Username']); } mysql_select_db($database_swb, $swb); $query_Ships4 = sprintf("SELECT * FROM ships WHERE PlayerName = %s AND Class=%s AND Template='1'", GetSQLValueString($colname_Ships4, "text"), GetSQLValueString($colname_Class4, "int")); $Ships4 = mysql_query($query_Ships4, $swb) or die(mysql_error()); $totalRows_Ships4 = mysql_num_rows($Ships4); $count = 0; while ($row = mysql_fetch_assoc($Ships4)){ $array[$count]['ShipID'] = $row['ShipID']; $array[$count]['ShipName'] = $row['ShipName']; $array[$count]['Class'] = $row['Class']; $count++; } $total4 = count($array4); $random4 = rand(0,$total4 - 1); $random_ship4 = $array4[$random4]; $ShipID4 = $random_ship4['ShipID']; $url4 = '<a href="add_ship.php?recordID='.$ShipID4.'">Test4</a>'; echo $url4;} On first look it seems fine, however once the page is refreshed the parsed recordID's both become the same number, e.g: Test3 recordID 8 Test4 recordID 24 then after refreshed: Test3 recordID 24 Test4 recordID 24 Is there anything wrong with my code??

If all you're doing is wanting to displaying a random row. Then there is no need to get all the rows from mysql and then choose a random row with PHP. MySQL can select a random row, example query. SELECT * FROM ships WHERE PlayerName = %s AND Class=%s AND Template='1' ORDER BY rand() LIMIT 1 Link to comment https://forums.phpfreaks.com/topic/235932-strange-results-from-an-array/#findComment-1212927 Share on other sites More sharing options...
