For the uploading part, here's some basic code:
<?php
if(@$_POST['MAX_FILE_SIZE']){ // If it is actually uploading
something...
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
//SET YOUR OWN UPLOAD DIR (absolute)
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)){
echo "File was successfully uploaded!\n You can access the file at:
http://".ROOT_DOMAIN.$uploaddir.basename($_FILES['userfile']['name'])."\n";
} else {
echo "Error! File was not uploaded!\n";
};
};
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>?admin=<?php echo
ADMIN_PAGE; ?>" method="POST" enctype="multipart/form-data">
<input type="hidden" name="MAX_FILE_SIZE" value="300000" />
<input type="file" name="userfile" /><br />
<input type="submit" value="Upload" />
</form>
You can find a basic image resizing script @ php.net under GD2
functions -
<?php
function CreateThumb($file,$maxwdt,$maxhgt, $dest) {
list($owdt,$ohgt,$otype)=@getimagesize($file);
switch($otype) {
case 1: $newimg=imagecreatefromgif($file); break;
case 2: $newimg=imagecreatefromjpeg($file); break;
case 3: $newimg=imagecreatefrompng($file); break;
default: echo "Unkown filetype (file $file, typ $otype)"; return;
}
if($newimg) {
if($owdt>1500 || $ohgt>1200)
list($owdt, $ohgt) = Resample($newimg, $owdt, $ohgt,
1024,768,0);
Resample($newimg, $owdt, $ohgt, $maxwdt, $maxhgt);
if(!$dest) return $newimg;
if(!is_dir(dirname($dest)))
mkdir(dirname($dest));
switch($otype) {
case 1: imagegif($newimg,dest); break;
case 2: imagejpeg($newimg,$dest,90); break;
case 3: imagepng($newimg,$dest); break;
}
imagedestroy($newimg);
chmod($dest,0644);
}
}
function Resample(&$img, $owdt, $ohgt, $maxwdt, $maxhgt, $quality=1) {
if(!$maxwdt) $divwdt=0;
else $divwdt=Max(1,$owdt/$maxwdt);
if(!$maxhgt) $divhgt=0;
else $divhgt=Max(1,$ohgt/$maxhgt);
if($divwdt>=$divhgt) {
$newwdt=$maxwdt;
$newhgt=round($ohgt/$divwdt);
} else {
$newhgt=$maxhgt;
$newwdt=round($owdt/$divhgt);
}
$tn=imagecreatetruecolor($newwdt,$newhgt);
if($quality)
imagecopyresampled($tn,$img,0,0,0,0,$newwdt,$newhgt,$owdt,$ohgt);
else
imagecopyresized($tn,$img,0,0,0,0,$newwdt,$newhgt,$owdt,$ohgt);
imagedestroy($img);
$img = $tn;
return array($newwdt, $newhgt);
}
?>
just use the function create thumb to set the dimensions and the
destination file
*There is a script that will work out the % size for you on php.net, if
you need %s*
