fxb9500 Posted June 4, 2010 Share Posted June 4, 2010 Hello, I am trying to get a page up where users can post a suggestion and other people can vote up it's popularity if they think it's a good idea. I have a column in the suggestion database called popularity (default of 1) that I am trying to change to it's current value + 1 when someone presses a button. I can not for the life of me figure out how this is done Here's my code: $editFormAction = $_SERVER['PHP_SELF']; if (isset($_SERVER['QUERY_STRING'])) { $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']); } if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) { $updateSQL = sprintf("UPDATE dbsuggestions SET popularity=%s WHERE `user`=%s", GetSQLValueString($_POST['voteup'], "text"), GetSQLValueString($_POST['voteup'], "text")); mysql_select_db($database_Database1, $Database1); $Result1 = mysql_query($updateSQL, $Database1) or die(mysql_error()); } $maxRows_dbsuggestions = 10; $pageNum_dbsuggestions = 0; if (isset($_GET['pageNum_dbsuggestions'])) { $pageNum_dbsuggestions = $_GET['pageNum_dbsuggestions']; } $startRow_dbsuggestions = $pageNum_dbsuggestions * $maxRows_dbsuggestions; mysql_select_db($database_Database1, $Database1); $query_dbsuggestions = "SELECT * FROM dbsuggestions"; $query_limit_dbsuggestions = sprintf("%s LIMIT %d, %d", $query_dbsuggestions, $startRow_dbsuggestions, $maxRows_dbsuggestions); $dbsuggestions = mysql_query($query_limit_dbsuggestions, $Database1) or die(mysql_error()); $row_dbsuggestions = mysql_fetch_assoc($dbsuggestions); if (isset($_GET['totalRows_dbsuggestions'])) { $totalRows_dbsuggestions = $_GET['totalRows_dbsuggestions']; } else { $all_dbsuggestions = mysql_query($query_dbsuggestions); $totalRows_dbsuggestions = mysql_num_rows($all_dbsuggestions); } $totalPages_dbsuggestions = ceil($totalRows_dbsuggestions/$maxRows_dbsuggestions)-1; ?> // and here's my actual form... <body class="Default"> <p>Here are some suggestions for new databases. If you like an idea, vote for it. </p> <p> </p> <?php do { ?> <table width="925" border="0"> <tr> <th width="137" height="36" scope="col"><?php echo $row_dbsuggestions['user']; ?></th> <th width="144" scope="col"><?php echo $row_dbsuggestions['email']; ?></th> <th width="298" scope="col"><?php echo $row_dbsuggestions['suggestion']; ?></th> <th width="177" scope="col"><?php echo $row_dbsuggestions['popularity']; ?></th> <th width="147" scope="col"><form name="form1" method="POST" action="<?php echo $editFormAction; ?>"> <input type="hidden" name="voteup" disabled="1" value="<?php echo $row_dbsuggestions['popularity']+1; ?>"> <input type="hidden" name="MM_update" value="form1"> <input name="submit" type="submit" class="Default" value="Good Idea"> </form></th> </tr> </table> That isn't the whole code... but thanks in advance for your help UPDATE: I realized I hadn't properly specified the primary key for the update, so I did that... and got a response from the server: column "popularity" can not be null Quote Link to comment Share on other sites More sharing options...
fxb9500 Posted June 4, 2010 Author Share Posted June 4, 2010 nevermind, I got it. the problem was the first GetSQLValueString here: if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) { $updateSQL = sprintf("UPDATE dbsuggestions SET popularity=%s WHERE `user`=%s", GetSQLValueString($_POST['voteup'], "text"), GetSQLValueString($_POST['voteup'], "text")); Quote Link to comment Share on other sites More sharing options...
