<?php

if (!$max_width)
$max_width = '500';
if (!$max_height)
$max_height = '500';

$size=GetImageSize($image);


$width=$size[0];
$height=$size[1];

$x_ratio=$max_width/$width;
$y_ratio=$max_height/$height;

if ( ($width <= $max_width) && ($height <= $max_height) ) {
$tn_width = $width;
$tn_height = $height;
}
else if (($x_ratio * $height) < $max_height) {
$tn_height = ceil($x_ratio * $height);
$tn_width = $max_width;
}
else {
$tn_width = ceil($y_ratio * $width);
$tn_height = $max_height;
}

switch ($size[2]) {
case 1: $src=imagecreatefromgif($image); break;
case 2: $src=imagecreatefromjpeg($image); break;
case 3: $src=imagecreatefrompng($image); break;
}

$dst=ImageCreateTrueColor($tn_width,$tn_height);
imagecopyresampled($dst, $src, 0, 0, 0, 0,$tn_width,$tn_height,$width,$height);
ImageJpeg($dst,null,-1);
ImageDestroy($src);
ImageDestroy($dst);

?>

ImageJpeg($dst,null,-1);

zmen na

ImageJpeg($dst,"obrazky/" . $meno_povodneho_suboru);

Moc diky jes se chci jeste zeptat jak z tohohle udelam funkci aby mi to fungovalo kdyz poslu pres formular (<input type="file"...) chtel udelat aby pokud nahravam obrazek tak aby to zmenilo velikost na 500 a ulozil obrazek ale nemuzu prijit na to jak to udelat diky moc

Petr:

HTML formular musi vypadat nejak takto:

<form method="post" enctype="multipart/form-data" action="upload.php">
<input type="file" name="uploaded_image">
<input type="submit" value="upload">
</form>

a kod v upload.php:

$type = $_FILES['uploaded_image']['type'];
$name = $_FILES['uploaded_image']['name'];
$tmp_name = $_FILES['uploaded_image']['tmp_name'];

if (eregi("image",$type)):

if (move_uploaded_file($tmp_name,"./$name")):

$image = "./$name";

// nyni prijde ten tvuj kod

else:

echo "nepodarilo se uploadovat";

endif;

else:

echo "Nespravny typ souboru";

endif;

Nejak tak, mozna jsou v tom chyby, dalsi me opravi :)
