[SOLVED] Certain queries aren't working with my new host

[roflcaesar]

Hi, I recently changed hosts, and I noticed that certain mysql scripts weren't working on my new host. I'm not really sure why, but anything that contains a variable in a query does nothing. This is what I have:

 

mysql_query("UPDATE addinatorz SET points=points+50 WHERE id='$ref'")
or die(mysql_error()); 

 

and

 

$sql="SELECT * FROM $tbl_name";
$result=mysql_query($sql);

$count=mysql_num_rows($result);

?>
<table width="400" border="0" cellspacing="1" cellpadding="0">
<tr>
<td><form name="form1" method="post" action="">
<table width="400" border="0" cellpadding="3" cellspacing="1" bgcolor="#CCCCCC">
<tr>
<td bgcolor="#FFFFFF"> </td>
<td colspan="4" bgcolor="#FFFFFF"><strong>Delete multiple rows in mysql</strong> </td>
</tr>
<tr>
<td align="center" bgcolor="#FFFFFF">#</td>
<td align="center" bgcolor="#FFFFFF"><strong>Id</strong></td>
<td align="center" bgcolor="#FFFFFF"><strong>Point</strong></td>
</tr>
<?php
while($rows=mysql_fetch_array($result)){
?>
<tr>
<td align="center" bgcolor="#FFFFFF"><input name="checkbox[]" type="checkbox" id="checkbox[]" value="<? echo $rows['id']; ?>"></td>
<td bgcolor="#FFFFFF"><? echo $rows['id']; ?></td>
<td bgcolor="#FFFFFF"><? echo $rows['points']; ?></td>
</tr>
<?php
}
?>
<tr>
<td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit" id="delete" value="Delete"></td>
</tr>
<?
if($delete){
for($i=0;$i<$count;$i++){
$del_id = $checkbox[$i];
$sql = "DELETE FROM $tbl_name WHERE id='$del_id'";
$result = mysql_query($sql);
}

if($result){
echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete.php\">";
}
}
mysql_close();
?>

 

 

Does anyone have any idea why these don't work with my new host or what I should do to fix them? Because I don't lol

Your code is dependent on register_globals to 'magically' populate program variables from post/get/session/cookie variables by the same name. Unfortunately, register_globals was a huge blunder by php.net because they also allow hackers to set your session variables to anything they want, causing a huge number of web sites to be taken over. register_globals were turned off by default in php4.2 in April of the year 2002. No code, books, tutorials, web host, or programmers should have relied on register_globals in their code nor should they have enabled them in php.ini. This security problem has been known for 7 years. There is no excuse for any code to still rely on register_globals at this date. Register_globals have been completely removed in php6.

 

You will need to fix your code so that it uses the proper $_POST, $_GET, $_SESSION, or $_COOKIE variables where the actual data is coming from.
