Hey all i have seen alot of options on how to rotate the image before being uploaded but the issue i have is i am not pro and i do not understand how to implement it into my codes.
Anyone kind enough to help me out with this?
here is my function to resize image
function resize_image($oldimage_name, $new_image_name){
list($owidth,$oheight) = getimagesize($oldimage_name);
$width = 250; $height = 250;
$im = imagecreatetruecolor($width, $height);
$img_src = imagecreatefromjpeg($oldimage_name);
imagecopyresampled($im, $img_src, 0, 0, 0, 0, $width, $height, $owidth, $oheight);
imagejpeg($im, $new_image_name, 90);
imagedestroy($im);
unlink($oldimage_name);
return true;
}
Here is my upload part
if($_FILES['file']['name']!='')
{
$tmp_name = $_FILES["file"]["tmp_name"];
$namefile = $_FILES["file"]["name"];
$cname = str_replace(' ', '-', $candidate_name);
$ext = end(explode(".", $namefile));
$fileUpload = move_uploaded_file($tmp_name,"uploads/images/".$image_name);
$image_name= $cname.'-'.time().".".$ext;
resize_image($tmp_name,"uploads/images/".$image_name);
$img = ''.$image_name.'';
}
And here is link to a site which has the option but i do not know how to make it work with my code.

I would like to resize, rename and upload an image with PHP.
So my working script is the following:
$file_name = $_FILES['HOT_Logo']['name'];
$file_tmp_name = $_FILES['HOT_Logo']['tmp_name'];
$file_target = '../../images/hotel-logos/';
$file_size = $_FILES['HOT_Logo']['size'];
// Resize
$ratio = $width/$height;
if($ratio > 1) {
$new_width = 300;
$new_height = 300/$ratio;
}
else {
$new_width = 300*$ratio;
$new_height = 300;
}
$src = imagecreatefromstring(file_get_contents($file_tmp_name));
$dst = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($dst, $src, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
imagedestroy($src);
imagepng($dst, $file_target.$file_name);
imagedestroy($dst);
// Rename file
$temp = explode('.', $_FILES['HOT_Logo']['name']);
$newfilename = 'new_img_name.'.end($temp);
// Upload image
if(move_uploaded_file($_FILES['HOT_Logo']['tmp_name'], $file_target.$newfilename)) {
...
}
Problem with this script is it upload two image:
The renamed image but unresized.
The non renamed image but resized.
Why ?
You are creating a image, then moving the uploaded file, which is why it's creating two files. I believe your code is supposed to be:
$file_name = $_FILES['HOT_Logo']['name'];
$file_tmp_name = $_FILES['HOT_Logo']['tmp_name'];
$file_target = '../../images/hotel-logos/';
$file_size = $_FILES['HOT_Logo']['size'];
// Resize
$ratio = $width/$height;
if($ratio > 1) {
$new_width = 300;
$new_height = 300/$ratio;
}
else {
$new_width = 300*$ratio;
$new_height = 300;
}
// Rename file
$temp = explode('.', $file_name);
$newfilename = 'new_img_name.'.end($temp);
// Upload image
if(move_uploaded_file($file_tmp_name , $file_target.$newfilename)) {
$src = imagecreatefromstring(file_get_contents($file_target.$newfilename));
$dst = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($dst, $src, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
imagedestroy($src);
imagepng($dst, $file_target.$newfilename);
imagedestroy($dst);
....
}
I need to resize image to 150 x 150 px and then upload it to Amazon S3
Following is the code:
$image = $_FILES["userImage"]["name"];
$fileTempName = $_FILES['userImage']['tmp_name'];
$new_width = 150;
$new_height = 150;
$image_p = imagecreatetruecolor($new_width, $new_height);
$image = imagecreatefromstring(file_get_contents($fileTempName));
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, imagesx($image), imagesy($image));
$newFielName = tempnam(sys_get_temp_dir(), "tempfilename");
imagepng($image_p, $newFielName, 9);
$s3 = new S3(awsAccessKey, awsSecretKey);
//move the file
if ($s3->putObjectFile($fileTempName, "urimages", $newFielName, S3::ACL_PUBLIC_READ)) {
$image_link = 'https://s3-us-west-2.amazonaws.com/urimages/' . $newFielName . '';
$this->Product->saveField('image', $image_link);
}
Following is the link which i receive upon uploading : https://s3-us-west-2.amazonaws.com/urimages/C:/Users/LS/AppData/Local/Temp/9102.tmp
Could be you please help me debug the code
i think issue in path. Please create folder on s3 and make a valid
path according to that folder
https://s3-us-west-2.amazonaws.com/urimages/C:/Users/LS/AppData/Local/Temp/9102.tmp
Example :- Resampling an image proportionally
<?php
// The file
$filename = 'test.jpg';
// Set a maximum height and width
$width = 200;
$height = 200;
// Content type
header('Content-Type: image/jpeg');
// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);
$ratio_orig = $width_orig/$height_orig;
if ($width/$height > $ratio_orig) {
$width = $height*$ratio_orig;
} else {
$height = $width/$ratio_orig;
}
// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);
// Output
imagejpeg($image_p, null, 100);
?>
I have this code which uploads images with watermarks. The code works fine but the watermark function re-resizes all the images upload to small width and height. I want to retain the size after adding the watermark. I believe the problem is in function but I don't know how to fix it.
if(isset($_FILES)){
$file = $_FILES['image'];
$allowedExts = array('jpg','png','gif','jpeg');
$uploadsDirectory = "imgupload/";
$maxSize = 2000000;
for($i = 0; $i < count($file['name']); $i++){
$filetmpname = $file['tmp_name'][$i];
$errors = array();
$filename = $file['name'][$i];
$filetext = strtolower(end(explode('.',$filename)));
$filesize = $file['size'][$i];
$filetmpname = $file['tmp_name'][$i];
if(in_array($filetext, $allowedExts) === FALSE){
$errors[] = "Extension is not allowed";
}
if($filesize > $maxSize){
$errors[] = "File Size must be less than {$maxSize} KB";
}
if(empty($errors)){
$random = rand(0,199);
$destination = $file['name'][$i] = $uploadsDirectory. $random."_".date("d-m-Y") . "_" . $file['name'][$i];
$upload_status = move_uploaded_file($filetmpname, $destination);
if($upload_status){
$new_name = $uploadsDirectory.$random."_".date("d-m-Y") . "_" .".jpg";
if(watermark_image($destination, $new_name))
$demo_image = $new_name;
}
}
}
}
Watermark Function:
$image_path = "images/water.png";
function watermark_image($oldimage_name, $new_image_name)
{
global $image_path;
list($owidth,$oheight) = getimagesize($oldimage_name);
$width = $height = 300;
$im = imagecreatetruecolor($width, $height);
$img_src = imagecreatefromjpeg($oldimage_name);
imagecopyresampled($im, $img_src, 0, 0, 0, 0, $width, $height, $owidth, $oheight);
$watermark = imagecreatefrompng($image_path);
list($w_width, $w_height) = getimagesize($image_path);
$pos_x = $width - $w_width;
$pos_y = $height - $w_height;
imagecopy($im, $watermark, $pos_x, $pos_y, 0, 0, $w_width, $w_height);
imagejpeg($im, $new_image_name, 100);
imagedestroy($im);
unlink($oldimage_name);
return true;
}
You are getting the size of the existing image here:
list($owidth,$oheight) = getimagesize($oldimage_name);
$width = $height = 300;
This is where it is making the different size image:
imagecopyresampled($im, $img_src, 0, 0, 0, 0, $width, $height, $owidth, $oheight);
http://php.net/manual/en/function.imagecopyresampled.php
//Your Image
$imgSrc = $_GET['f'];
list($width, $height) = getimagesize($imgSrc);
list($root) = explode('httpdocs', __FILE__);
$root = $root.'httpdocs';
$savePath = $root.'/_m/chacheImages/';
$savePath = '../cacheImages/';
$imgName = basename($imgSrc);
list($imgName) = explode('.', $imgName);
$fileName = $savePath.$imgName.'.jpg';
if($width > 0 && $height > 0){
$thumbSize = 100;
$img_p = imagecreatetruecolor($width, $height);
$img = imagecreatefrompng($imgSrc);
imagecopyresampled($img_p, $img, -10, 0, 0, 10, $width+30, $height, ($width), ($height-20));
//header('Content-type: image/png');
imagejpeg($img_p, $fileName);
imagedestroy($img_p);
}
I can't seem to get this to work. If i delete $fileName at imagejpeg it shows the image correctly.
But it won't save the images. What am I doing wrong?
I have a bit of code that generates thumbnails from an uploaded image. The only problem is that it cuts portrait images off, rather than resizing the portrait image to fit the height of the thumbnail, landscape images are fine. I was wondering if anyone could help me out to change the code so it will place portrait images inside the thumbnail properly? (if that makes sense?)
Here's the code:
$setSize = 150;
$setHSize = 113;
$jpeg_quality = 75;
list($width, $height, $type, $attr) = getimagesize($origPath);
$newW = $setSize;
$newH = round( $height * ( $setSize / $width ) );
$img_r = imagecreatefromjpeg($origPath) or notfound();
$dst_r = ImageCreateTrueColor( $setSize, $setHSize );
$heightOffset = round( ($setHSize-$newH)/2 );
$white = imagecolorallocate($dst_r, 255, 255, 255);
imagefilledrectangle($dst_r, 0, 0, $setSize, $setHSize, $white);
imagecopyresampled($dst_r, $img_r, 0, $heightOffset, 0, 0, $newW, $newH, $width, $height);
header("Content-type: image/jpeg");
imagejpeg($dst_r, $thbPath, $jpeg_quality);
I just don't fully understand the way php creates images, so any help would be appreciated :)
The way you compute $newW and $newH is incorrect for what you want. You are giving preference to the width, so most landscape images will look okay, but portrait will be cut off. Try the following instead:
// assume landscape and see how things look
$newW = $setSize;
$newH = round( $height * ( $setSize / $width ) );
if ($newH > $setHSize) {
// portrait image
$newH = $setHSize;
$newW = round( $width * ( $setHSize / $height ) );
}
I hope this helps!
Hope this helps.
