rezise billederne ned til 125 x 190 px i upload

Du kan muligvis bruger funktionen resize i stedet for:
move_uploaded_file().

function resize( $filename, $newfilename, $maxw, $maxh )
{
    list($width, $height, $filetype, $attr) = getimagesize($filename);
    $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 );
    imagejpeg( $dstim, $newfilename, 85 );
    imagedestroy( $dstim );
    imagedestroy( $srcim );
    return file_exists($newfilename);
}

PS: Denne funktion virker kun på jpg/jpeg/jpe filer.

og hvordan skal dette så sættes ind i scriptet

Denne smider du øverst i dine kode:

function resize( $filename, $newfilename, $maxw, $maxh )
{
    list($width, $height, $filetype, $attr) = getimagesize($filename);
    $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 );
    imagejpeg( $dstim, $newfilename, 85 );
    imagedestroy( $dstim );
    imagedestroy( $srcim );
    return file_exists($newfilename);
}

og så retter du:
move_uploaded_file($_FILES['images']['tmp_name'],"images/".$newname);
til:
resize($_FILES['images']['tmp_name'],"images/".$newname,125,190);

sådan her

<?php

$id = $_SESSION['navn'];
include("access.php");
$maxfilesize = 81920;

function resize( $filename, $newfilename, $maxw, $maxh )
{
    list($width, $height, $filetype, $attr) = getimagesize($filename);
    $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 );
    imagejpeg( $dstim, $newfilename, 85 );
    imagedestroy( $dstim );
    imagedestroy( $srcim );
    return file_exists($newfilename);
}

// check if there was a file uploaded

// if it was, go ahead with other checks

        $error = "Dit Profil billed er for stort.<br />";
        unlink($_FILES['images']['tmp_name']);

            $error = "Dit profil billed er af forkert filtype.<br />";
            unlink($_FILES['images']['tmp_name']);
        // if it's there, an okay size and type, copy to server and update the photo value in SQL
        } else {
            if ($_SESSION['images'] != "nopic.jpg") {
                unlink("/images/".$_SESSION['images']);
            }
            $newname = $_SESSION['images'].$ext;
          resize($_FILES['images']['tmp_name'],"images/".$newname,125,190);
            mysql_query("UPDATE login SET images='$newname' WHERE user = '".$id."'"; or die (mysql_error());
            $_SESSION['images'] = $newname;

Det ser rigtigt ud ja...

sorry

det gale script denne her virker men mangler funktionen rezise

<?php

}

den skriver at filen er for stor

kan man bare fjerne dette $maxfilesize = 81920; samt i formen

  <form action="changephotoparse.php" method="post" enctype="multipart/form-data">
                    <strong>
<input type="hidden" name="MAX_FILE_SIZE" value="81920">
Profil billed:</strong>                   
                    <input type="file" name="file"><br /><br />
<input type="submit" name="submit" value="Upload Profil billed"></form>

jeg har fjernet begge $maxfilesize = 81920; men scriptet virker ikke fordi billedet er for stort

Du kunne evt øge size... både: value="81920 og $maxfilesize = 81920
Eller helt fjern tjekket:

if ($_FILES['file']['size'] > $maxfilesize) {
        $error = "Dit Profil billed er for stort.<br />";
        unlink($_FILES['file']['tmp_name']);
    } else

nu ser scriptet således ud men skræmen bliver bare hvid

nu for jeg en ny fejl

husk at vælge en fil der skal uploades

på scriptet

den skriver i mysql men der kommer igen fil ud i mappen "files" på serveren

har ændret den til ovennævte men nu skriver den ikke mere i db og den oploader heller ikke men der kommer igen fejl

den kommer kun med

Dit nye profil billed er blevet oploadet.  se din nye profil klik her

Den bør da komme med en tekst når du bare åbner siden med koden her over.

Kontakt mig lige på msn: jakobdo (at) hotmail [dot] com

Og et svar!

det færdig arbejde efter stor hjælp af Jakobdo så ser koden således ud
