Upload image with resize in php - php

Question

I have a problem with image uploading in php
I want uploading with resizing image to width=600px
ex, when I uploaded an image with width of 2000px it should be uploaded with width of 600px
and of course smaller size on disk...
php file is:
<?php
require_once("db.php");
$name = trim($_POST['name']);
$addr = trim($_POST['addr']);
$dist = trim($_POST['dist']);
$city = trim($_POST['city']);
$phone = trim($_POST['phone']);
$price = trim($_POST['price']);
$lati = trim($_POST['lati']);
$long = trim($_POST['long']);
$tid = trim($_POST['type']);
$img = "";
if($_FILES)
{
//var_dump($_FILES);
$random_str = md5(uniqid(mt_rand(), true));
$f_name = "tmp/".$random_str.".jpg";
move_uploaded_file($_FILES['placeimg']['tmp_name'], $f_name);
$img = 'http://'.$_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF'])."/".$f_name;
$uploadedfile = $_FILES['placeimg']['tmp_name'];
$size=filesize($_FILES['placeimg']['tmp_name']);
$uploadedfile =$_FILES['placeimg']['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);
list($width,$height)=getimagesize($_FILES['placeimg']['tmp_name']);
$newwidth=600;
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);
//$filename = "tmp/". $_FILES['file']['name'];
imagejpeg($tmp,$uploadedfile,75);
imagedestroy($src);
}
$sql = "INSERT INTO `Place`(`PName`, `PAddr`, `PDistrict`, `PCity`, `PImage`, `PPhone`, `PPrice`, `PLat`, `PLong`, `TID`, `PStatus`) VALUES ('{$name}', '{$addr}', '{$dist}', '{$city}', '{$img}', '{$phone}', '{$price}', '{$lati}', '{$long}', '{$tid}', '0')";
$status = 0;
$mess = "Err!";
if(mysql_query($sql))
{
$status = 1;
$mess = "Successful! Waiting approve";
}
$json['status'] = $status;
$json['message'] = $mess;
echo json_encode($json);
?>
the result is a big image without resizing
can you help?

try this:
function upload_resize($file,$newwidth,$resolution,$location,$prefix){
define ("MAX_SIZE","2048");
error_reporting(0);
$image =$file["name"];
$uploadedfile = $file['tmp_name'];
if ($image) {
$filename = stripslashes($file['name']);
$extension = getExtension($filename);
$extension = strtolower($extension);
if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) {
//Unknown Image extension
return 1;
}
else
{
$size=filesize($file['tmp_name']);
if ($size > MAX_SIZE*1024){
//You have exceeded the size limit
return 2;
}
if($extension=="jpg" || $extension=="jpeg" ) {
$uploadedfile = $file['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);
}
else if($extension=="png") {
$uploadedfile = $file['tmp_name'];
$src = imagecreatefrompng($uploadedfile);
}
else {
$src = imagecreatefromgif($uploadedfile);
}
list($width,$height)=getimagesize($uploadedfile);
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);
imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
$filename = $location.$prefix.$file['name'];
imagejpeg($tmp,$filename,$resolution);
imagedestroy($src);
imagedestroy($tmp);
}
}
return 0;
}
function getExtension($str) {
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
// get file from user and send to this function:
$res=upload_resize($_FILES["image"],600,100,'../images','');
switch ($res){
case 0 : echo 'images saved'; break;
case 1 : echo 'Unknown file type'; break;
case 2 : echo 'file size error'; break;
}
i use this function for upload and resize image.

Answer 2

// for outputting a jpeg image, Set the content type header - in this case image/jpeg
header('Content-Type: image/jpeg');
// Output the image
imagejpeg($tmp,$uploadedfile,75);
try this..

Answer 3

You create a new pattern file (using imagecreatetruecolor), but u didn't use a original picture.
Try use imagecopyresampled
like this:
<?php
require_once("db.php");
$name = trim($_POST['name']);
$addr = trim($_POST['addr']);
$dist = trim($_POST['dist']);
$city = trim($_POST['city']);
$phone = trim($_POST['phone']);
$price = trim($_POST['price']);
$lati = trim($_POST['lati']);
$long = trim($_POST['long']);
$tid = trim($_POST['type']);
$img = "";
if($_FILES)
{
//var_dump($_FILES);
$random_str = md5(uniqid(mt_rand(), true));
$f_name = "tmp/".$random_str.".jpg";
move_uploaded_file($_FILES['placeimg']['tmp_name'], $f_name);
$img = 'http://'.$_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF'])."/".$f_name;
$uploadedfile = $_FILES['placeimg']['tmp_name'];
$size=filesize($_FILES['placeimg']['tmp_name']);
$uploadedfile =$_FILES['placeimg']['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);
list($width,$height)=getimagesize($_FILES['placeimg']['tmp_name']);
$newwidth=600;
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);
$buff = imagecreatefromjpeg($uploadedfile);
imagecopyresampled($tmp, $b, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
//$filename = "tmp/". $_FILES['file']['name'];
imagejpeg($tmp,$uploadedfile,75);
imagedestroy($src);
}
$sql = "INSERT INTO `Place`(`PName`, `PAddr`, `PDistrict`, `PCity`, `PImage`, `PPhone`, `PPrice`, `PLat`, `PLong`, `TID`, `PStatus`) VALUES ('{$name}', '{$addr}', '{$dist}', '{$city}', '{$img}', '{$phone}', '{$price}', '{$lati}', '{$long}', '{$tid}', '0')";
$status = 0;
$mess = "Err!";
if(mysql_query($sql))
{
$status = 1;
$mess = "Successful! Waiting approve";
}
$json['status'] = $status;
$json['message'] = $mess;
echo json_encode($json);
?>
