Ich habe es geschafft das wenn ein User sein Bild (Avatar) Uploaden will, dass dieses dann verkleinert wird.
Der Code ist folgender:
// Filename to store image as
$FILENAME="test";
// Width to reszie image to
$RESIZEWIDTH=100;
// Width to reszie image to
$RESIZEHEIGHT=75;
function ResizeImage($im,$maxwidth,$maxheight,$name){
$width = imagesx($im);
$height = imagesy($im);
if(($maxwidth && $width > $maxwidth) || ($maxheight && $height > $maxheight)){
if($maxwidth && $width > $maxwidth){
$widthratio = $maxwidth/$width;
$RESIZEWIDTH=true;
}
if($maxheight && $height > $maxheight){
$heightratio = $maxheight/$height;
$RESIZEHEIGHT=true;
}
if($RESIZEWIDTH && $RESIZEHEIGHT){
if($widthratio < $heightratio){
$ratio = $widthratio;
}else{
$ratio = $heightratio;
}
}elseif($RESIZEWIDTH){
$ratio = $widthratio;
}elseif($RESIZEHEIGHT){
$ratio = $heightratio;
}
$newwidth = $width * $ratio;
$newheight = $height * $ratio;
if(function_exists("imagecopyresampled")){
$newim = imagecreatetruecolor($newwidth, $newheight);
imagecopyresampled($newim, $im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
}else{
$newim = imagecreate($newwidth, $newheight);
imagecopyresized($newim, $im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
}
ImageJpeg ($newim,$name . ".jpg");
ImageDestroy ($newim);
}else{
ImageJpeg ($im,$name . ".jpg");
}
}
if($_FILES['image']['size']){
if($_FILES['image']['type'] == "image/pjpeg" || $_FILES['image']['type'] == "image/jpeg"){
$im = imagecreatefromjpeg($_FILES['image']['tmp_name']);
}elseif($_FILES['image']['type'] == "image/x-png" || $_FILES['image']['type'] == "image/png"){
$im = imagecreatefrompng($_FILES['image']['tmp_name']);
}elseif($_FILES['image']['type'] == "image/gif"){
$im = imagecreatefromgif($_FILES['image']['tmp_name']);
}
if($im){
if(file_exists("data/avatars/$FILENAME.jpg")){
unlink("data/avatars/$FILENAME.jpg");
}
ResizeImage($im,$RESIZEWIDTH,$RESIZEHEIGHT,$FILENAME);
ImageDestroy ($im);
}
}
Ich habs zunächst in der member.php eingebaut!
Öffne: member.php
Suche:
$main_template = "member";
define('GET_CACHES', 1);
define('ROOT_PATH', './');
include(ROOT_PATH.'global.php');
require(ROOT_PATH.'includes/sessions.php');
$user_access = get_permission();
include(ROOT_PATH.'includes/page_header.php');
if ($action == "") {
$action = "lostpassword";
}
Danach einfügen:
// Filename to store image as
$FILENAME="test";
// Width to reszie image to
$RESIZEWIDTH=100;
// Width to reszie image to
$RESIZEHEIGHT=75;
function ResizeImage($im,$maxwidth,$maxheight,$name){
$width = imagesx($im);
$height = imagesy($im);
if(($maxwidth && $width > $maxwidth) || ($maxheight && $height > $maxheight)){
if($maxwidth && $width > $maxwidth){
$widthratio = $maxwidth/$width;
$RESIZEWIDTH=true;
}
if($maxheight && $height > $maxheight){
$heightratio = $maxheight/$height;
$RESIZEHEIGHT=true;
}
if($RESIZEWIDTH && $RESIZEHEIGHT){
if($widthratio < $heightratio){
$ratio = $widthratio;
}else{
$ratio = $heightratio;
}
}elseif($RESIZEWIDTH){
$ratio = $widthratio;
}elseif($RESIZEHEIGHT){
$ratio = $heightratio;
}
$newwidth = $width * $ratio;
$newheight = $height * $ratio;
if(function_exists("imagecopyresampled")){
$newim = imagecreatetruecolor($newwidth, $newheight);
imagecopyresampled($newim, $im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
}else{
$newim = imagecreate($newwidth, $newheight);
imagecopyresized($newim, $im, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
}
ImageJpeg ($newim,$name . ".jpg");
ImageDestroy ($newim);
}else{
ImageJpeg ($im,$name . ".jpg");
}
}
if($_FILES['image']['size']){
if($_FILES['image']['type'] == "image/pjpeg" || $_FILES['image']['type'] == "image/jpeg"){
$im = imagecreatefromjpeg($_FILES['image']['tmp_name']);
}elseif($_FILES['image']['type'] == "image/x-png" || $_FILES['image']['type'] == "image/png"){
$im = imagecreatefrompng($_FILES['image']['tmp_name']);
}elseif($_FILES['image']['type'] == "image/gif"){
$im = imagecreatefromgif($_FILES['image']['tmp_name']);
}
if($im){
if(file_exists("data/avatars/$FILENAME.jpg")){
unlink("data/avatars/$FILENAME.jpg");
}
ResizeImage($im,$RESIZEWIDTH,$RESIZEHEIGHT,$FILENAME);
ImageDestroy ($im);
}
}
Öffne: templates/dein template/members_editprofil.html
Suche:
{lang_upload}
<INPUT type="file" name="avatar_file" size="30" class="input" />
Ersetze mit:
Upload vom Computer:<br />
<input type="file" name="image" size="35" class="input"><br /><input type="submit" value="upload" class="button">
Man kann es auch extra zu dem normalen Upload hinzufügen!
Das klappt wunderbar.
Aber nun zu ein paar kleinen dingen die mich stören!
Wie bekomme ich das hin, dass ich in diesem code:
// Filename to store image as
$FILENAME="test";
Den Username als Filename nehmen kann? Also ich habe da z.B Test genommen, aber ich möchte sowas in der Art "user_name", also das dieses Bild dann quasi als "Phisker.jpg" erstellt wird. Ich habe keine Ahnung davon, das mit diesem Code war auch nur Zufall das es klappte.
Dann kommt nich eines, ich habe angegeben:
if(file_exists("data/avatars/$FILENAME.jpg")){
unlink("data/avatars/$FILENAME.jpg");
Aber das hochgeladene Bild wird nicht im data/avatars erstellt, sondern immer nur im root Verzeichnis!
Bitte um Hilfe!
Gruß
