remove register globals

[izlik]

Hey there.

 

im a beginner at php and started trying to make a tag script, and i got told i almost got it to work, i just need to make it so $pagenum and $tag wont register globals and i right now have no clue how to do that.

 

i wonder if anyone could help me make it so $pagenum and $tag wont register globals in the code bwllow?

 

<?php

$con = mysql_connect("localhost","asd","das") OR die('Could not connect: ' . mysql_error());
mysql_select_db("asd", $con);

//This checks to see if there is a page number. If not, it will set it to page 1
if (!(isset($pagenum)))
{
$pagenum = 1;
}

$result = mysql_query("
    SELECT *
    FROM `images`
    WHERE `tags`
    LIKE '%" . mysql_real_escape_string($_GET['tag']) . "%'
    ORDER BY views
    $max
")
OR die(mysql_error());
$rows = mysql_num_rows($result);

//This is the number of results displayed per page
$page_rows = 30;

$last = ceil($rows/$page_rows);

if ($pagenum < 1)
{
$pagenum = 1;
}
elseif ($pagenum > $last)
{
$pagenum = $last;
}

$max = 'limit ' .($pagenum - 1) * $page_rows .',' .$page_rows;

while($row = mysql_fetch_array($result))
{
    
    echo '<div style="float:left;width:25%"><a href="http://mydomain.net/show.php/' .$row['id'].'_' .$row['name'].'"><img src="http://www.mydomain.net/out.php/t' .$row['id'].'_' .$row['name'].'"></a></div>';
    echo "<br>\n";

}   

?>
<div style="clear:both"></div>
<?  

    echo " --Page $pagenum of $last-- <p>";
   
    if ($pagenum == 1)
{
}
else
{
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=1&tag={$_GET['tag']}'> <<-First</a> ";
echo " ";
$previous = $pagenum-1;
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$previous&tag={$_GET['tag']}'> <-Previous</a> ";
}

//just a spacer
echo " ---- ";

if ($pagenum == $last)
{
}
else {
$next = $pagenum+1;
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$next&tag={$_GET['tag']}'>Next -></a> ";
echo " ";
echo " <a href='{$_SERVER['PHP_SELF']}?pagenum=$last&tag={$_GET['tag']}'>Last ->></a> ";
}
?>

run your php info

<?php
phpinfo();
?>

and show a link or find registered globals

[PHP_PhREEEk]

$pagenum is coming from a URL using GET or POST. We can't tell without looking at the relevant code. At any rate, with register_globals ON, these values are automatically converted to $pagenum. With register_globals OFF, you have to access these values with $_GET['pagenum'] or $_POST['pagenum'], whichever is appropriate. You can convert them like so:

 

<?php
$pagenum = $_GET['pagenum'] // or $_POST if applicable
?>

 

Then you can use $pagenum as desired and turn OFF register_globals in php.ini
