resize bredde og højde

Overvej at smid billederne igennem denne inden du gemmer det:
function resize( $filename, $newfilename, $maxw, $maxh )
{
    $result = false;
    $srcim = imagecreatefromjpeg( $filename );
    $ow = imagesx( $srcim );
    $oh = imagesy( $srcim );
    $wscale = $maxw / $ow;
    $hscale = $maxh / $oh;
    $scale = ( $hscale < $wscale ? $hscale : $wscale );
    $nw = round( $ow * $scale, 0 );
    $nh = round( $oh * $scale, 0 );
    $dstim = imagecreatetruecolor( $nw, $nh );
    imagecopyresampled( $dstim, $srcim, 0, 0, 0, 0, $nw, $nh, $ow, $oh );
    $result = imagejpeg( $dstim, $newfilename, 85 );
    imagedestroy( $dstim );
    imagedestroy( $srcim );
    return $result;
}

Hvordan vil du implementere det i den her :

<?php
include("../includes/config.inc.php");
$idaktuelt = $_REQUEST['idaktuelt'];
// Do this process if user has browse the file and click the submit button
if ($_FILES) {
  $image_types = Array ("image/bmp",
                        "image/jpeg",
                        "image/jpg",
                        "image/pjpeg",
                        "image/gif",
                        "image/x-png");

  $userfile  = addslashes (fread (fopen ($_FILES["userfile"]["tmp_name"], "r"), filesize ($_FILES["userfile"]["tmp_name"])));
  $file_name = $_FILES["userfile"]["name"];
  $file_size = $_FILES["userfile"]["size"];
  $file_type = $_FILES["userfile"]["type"];

  if (in_array (strtolower ($file_type), $image_types)) {
    $sql = "INSERT INTO image (image_type, image, image_size, image_name, idaktuelt) ";
    $sql.= "VALUES (";
    $sql.= "'{$file_type}', '{$userfile}', '{$file_size}', '{$file_name}','$idaktuelt')";
    @mysql_query ($sql);
    echo '<script>alert("Tilføjet");</script>';
    ?>
    <script>document.location.href="imagedit-aktuelt-show.php?idaktuelt=<?=$idaktuelt?>"</script>
    <?
    exit();
  }
}
?>

Du skal gøre det inden:
resize($_FILES["userfile"]["tmp_name"],"tmpFile.extension",800,800);
$userfile  = addslashes (fread (fopen ("tmpFile.extension", "r"), filesize ($_FILES["userfile"]["tmp_name"])));

Får denne  fejl:

Warning: fopen(tmpFile.extension) [function.fopen]: failed to open stream: No such file or directory in c:\websteder\admin\imagedit-aktuelt-ok.php on line 32

Warning: fread(): supplied argument is not a valid stream resource in c:\websteder\admin\imagedit-aktuelt-ok.php on line 32

min fejl, havde glemt at køre den igennem funktionen :)

Det virker kanon, lægger du et svar?

Svar!

Takker for point!
