Kombiner to scripts - De virker hver for sig
Jeg har to scripts - et som uploader billeder og et som resizer. Jeg har forgæves forsøgt at sætte dem sammen men det er ikke lykkedes. Kan nogen hjælpe?Målet er at billeder skal uploades, resizes og renames.
Resize-scriptet ser sådan her ud
<?php
function resize( $file_name, $newfilename, $maxw, $maxh, $quality=85 )
{
$ext = strtolower( pathinfo( $file_name, PATHINFO_EXTENSION ) );
switch($ext)
{
case 'jpeg':
case 'jpe':
case 'jpg':
$srcim = imagecreatefromjpeg( $file_name );
break;
case 'gif':
$srcim = imagecreatefromgif( $file_name );
break;
case 'png': $srcim = imagecreatefrompng( $file_name );
break;
default:
return false;
}
$ow = imagesx( $srcim );
$oh = imagesy( $srcim );
$wscale = $maxw / $ow;
$hscale = $maxh / $oh;
$scale = min( $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, $oh ); switch($ext)
{
case 'jpeg':
case 'jpe':
case 'jpg':
imagejpeg( $dstim, $newfilename, $quality );
break;
case 'gif':
imagegif( $dstim, $newfilename );
break;
case 'png': $png_q = floor( abs( $quality / 10 - 9.9 ) );
imagepng( $srcim, $newfilename, $png_q );
break;
default:
return false;
}
imagedestroy( $dstim );
imagedestroy( $srcim );
return file_exists($newfilename);
} // Slut function resize()
#--------------------------#
# Her resizes billederne #
#--------------------------# list($bredde, $hojde) = getimagesize("$file_name");
//Finder højden og bredden på det billede jeg vil resize
$forhold = $bredde/$hojde;
//Hvor stor er højden i forhold til bredden?
//Finder den nye og bredde
$bredde_ny = round($hojde_ny*$forhold);
// Her kører resize-funktionen
resize("$file_name", "$file_name", "$bredde_ny", "$hojde_ny");
#------------------------------------------------------------#
?>
Mit upload-script ser sadån her ud
<?php
//upload directory.
$upload_dir = "pictures/";

// Her sættes højden som billederne skal resizes til
$hojde_ny = 300;
