Resizing Images

[bluewaves]

I need to add a function to a php script that calls on a mysql database and displays product images from a datafeed on a web page.

 

I have a variety of image sizes. For example, one image is 400 x 212. When I display it I want it to be a maximum width of 250, then I want the height to be whatever it needs to be to keep it in a similar proportion to the original.

 

Can someone tell me how I would write that into my php script?

 

Thanks.

Mainly

 

$destination_handle = imagecreatetruecolor( $thumbnail_width, $thumbnail_height );

ImageCopyResampled( $destination_handle, $source_handle, 0, 0, 0, 0, $thumbnail_width, $thumbnail_height, $size[0], $size[1] );

How can I get this to work with this code:

 

<?php

include('bbbb.php');

  $database = "cxxxxx";

  $cxn = mysql_connect($host,$user,$password)

         or die ("couldn't connect to server");

  mysql_select_db($database);
$conn = mysql_connect('localhost','x','x') or trigger_error("SQL", E_USER_ERROR);   
$db = mysql_select_db('coolchec_checks',$conn) or trigger_error("SQL", E_USER_ERROR); 

// find out how many rows are in the table 
$sql = "SELECT COUNT(*) FROM table WHERE Type='movie' ORDER BY ProductID DESC";
$result = mysql_query($sql, $cxn) or trigger_error("SQL", E_USER_ERROR);
$r = mysql_fetch_row($result);
$numrows = $r[0];

// number of rows to show per page
$rowsperpage = 30;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);

// get the current page or set a default
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
   // cast var as int
   $currentpage = (int) $_GET['currentpage'];
} else {
   // default page num
   $currentpage = 1;
} // end if

// if current page is greater than total pages...
if ($currentpage > $totalpages) {
   // set current page to last page
   $currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
   // set current page to first page
   $currentpage = 1;
} // end if

// the offset of the list, based on current page 
$offset = ($currentpage - 1) * $rowsperpage;

// get the info from the db 
$sql = "SELECT  BigImage, Thumbnail, Link, Name, Description, Price FROM table WHERE Type='Movie' ORDER BY ProductID DESC LIMIT $offset, $rowsperpage";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);

define ("NUMCOLS", 1);


$res = mysql_query("SELECT BigImage, Thumbnail, Link, Name, Description, Price FROM gobble WHERE Type='Movie' ORDER BY ProductID DESC");


$count = 0;

echo "<table cellpadding='10'>";

while ($list = mysql_fetch_assoc($result)) 

{



    if ($count % NUMCOLS == 0) echo "<tr>\n";  # new row



     echo "<td><a href='". $list['Link'] . "' rel='nofollow' title='" . $list['Name'] . "' target='_blank'>

     $count++;



    if ($count % NUMCOLS == 0) echo "</tr>\n";  # end row

}



# end row if not already ended



if ($count % NUMCOLS != 0) {

   while ($count++ % NUMCOLS) echo "<td> </td>";

   echo "</tr>\n";

}

echo "</table>";
