gwolff2005 Posted March 29, 2011 Share Posted March 29, 2011 Hi I have the file "pback.php" which displays a mysql table. One row allows me to update the data. If I press "update it leads me to update.php, but there I just get white fields instead of the data from the id requested. If I type anything in the field and press confirm it opens update_ac but just says error. What do I do wrong? Thanks! pback.php <?php $host="xxx"; // Host name $username="xxx"; // Mysql username $password="xxx"; // Mysql password $db_name="xxx"; // Database name $tbl_name="sp_users"; // Table name // Connect to server and select database. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); //$sql="SELECT * FROM $tbl_name ORDER BY user_id"; $sql="SELECT * from sp_users,sp_schools where sp_users.user_id=sp_schools.school_id ORDER BY school_name"; $result=mysql_query($sql); $num_rows=mysql_num_rows($result); ?> <style type="text/css"> <!-- .style2 {font-weight: bold} .style3 { font-family: Arial, Helvetica, sans-serif; color: #000000; } .style10 {font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 10px; color: #000000; } #Layer1 { position:absolute; left:803px; top:36px; width:65px; height:28px; z-index:1; } #Layer2 { position:absolute; left:707px; top:19px; width:143px; height:39px; z-index:1; } --> </style> <title>User overview</title> </html> <div id="Layer2"> <form action="<?= $_SERVER['PHP_SELF'] ?>" method="post"> <input type="hidden" name="foo" value="<?= $foo ?>" /> <input type="submit" name="submit" value="Refresh" /> </form></div> <table width="779" border="0" align="left" cellpadding="0" cellspacing="1" bgcolor="#996600"> <tr> <td width="777"> <div align="left"> <table width="779" border="1" cellspacing="0" cellpadding="3"> <tr> <td colspan="6" align="center"><div align="center" class="style1 style3"><strong>SchoolPorta.com Users / Total: <?php echo $num_rows ?></strong></div></td> </tr> <tr> <td width="342" align="center"><span class="style2">school</span></td> <td width="62" align="center"><span class="style2">Name</span></td> <td width="104" align="center"><span class="style2">Lastname</span></td> <td width="130" align="center"><span class="style2">Email</span></td> <td width="64" align="center"><span class="style2">Update</span></td> </tr> <?php while($rows=mysql_fetch_array($result)){ ?> <tr> <td><span class="style10"><?
