PHP - Resizing Uploaded Image From Server

Hello. I'm using an Amazon S3 class to uploaded to S3. I have 2 upload boxes - The first uploads once and the second needs to upload twice - 1 full size, 1 thumb.

The issue i'm having is that the 2nd image (the thumb) seems to be failing, although if I don't save the first full sized image I am able to upload the thumb. So I think the issue is with using the temp file twice?

This is my code:

 //retreive post variables

$fileName = $randomString . "_" . $_FILES['theFile']['name'];

$fileTempName = $_FILES['theFile']['tmp_name'];

$fileName2 = $randomString . "_" . $_FILES['theFile2']['name'];

$fileTempName2 = $_FILES['theFile2']['tmp_name'];

    //move the file

if ($s3->putObjectFile($fileTempName, "containerhere", $fileName, S3::ACL_PUBLIC_READ)) {

echo "<strong>Uploaded Image</strong>";

}else{

echo "<strong>Something went wrong while uploading your file... sorry.</strong>";

}

//move the file

if ($s3->putObjectFile($fileTempName2, "containerhere", $fileName2, S3::ACL_PUBLIC_READ)) {

echo "<strong>Uploaded Image</strong>";

}else{

echo "<strong>Something went wrong while uploading your file... sorry.</strong>";

}

  include('simpleImage.php');

  $image = new SimpleImage();

  $image->load($_FILES['theFile2']['tmp_name']);

  $image->resizeToWidth(100);

  $image->save($_FILES['theFile2']['tmp_name']);

$fileName3 = $randomString . "_" . $_FILES['theFile2']['name'];

$fileTempName3 = $_FILES['theFile2']['tmp_name'];

//move the file

if ($s3->putObjectFile($fileTempName3, "containerhere", "thumbs/" . $fileName3, S3::ACL_PUBLIC_READ)) {

echo "<strong>Uploaded Image</strong>";

}else{

echo "<strong>Something went wrong while uploading your file... sorry.</strong>";

}

Can anyone offer any advice?

Thanks.

Hi everyone, I have a script below, which uplads an image, however, the image name always starts with a capital letter, I want all letters to be small, how to adjust this please, thank you

 

$target_dir = "";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$target_file = "$get_current_user.jpg";


$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));


// Check if image file is a actual image

if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo ""; /// was File is an image
        $uploadOk = 1;
    } else {
        echo "File is not an image<br>";
        $uploadOk = 0;
    }
}


// Check file size

if ($_FILES["fileToUpload"]["size"] > 10000000) {
    echo "Sorry, this image is too large, please resize using Paint<br>";
    $uploadOk = 0;
}

// Allow certain file formats

if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif" ) {
    echo "Only JPG, JPEG, PNG & GIF files are allowed<br>";
    $uploadOk = 0;
}


// Check if $uploadOk is set to 0 by an error

if ($uploadOk == 0) {

    echo "There was an error<br>";


} else {


    if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {

       echo "Uploaded successfully (You may need to clear Cache to see the new image)";
	   mysql_query("UPDATE user SET user_image = 'https://.../images/users/$get_current_user.jpg' WHERE user_name = '$get_current_user' ");

    } else {

        echo ""; /// was Select a suitable image, file not uploaded yet

    }

}

 

Hey guys!
I have the following php code that grabs variables (and the browsed image) from Flash.


//FLASH VARIABLES
$Name = $_POST['Name'];
$itemNumber = $_POST['itemNumber'];
$filename = $_FILES['Filedata']['name'];
$filetmpname = $_FILES['Filedata']['tmp_name'];
$fileType = $_FILES["Filedata"]["type"];
$fileSizeMB = ($_FILES["Filedata"]["size"] / 1024 / 1000);


list($filename, $extension) = explode('.', basename($_FILES['Filedata']['name']));
$filename = $Name;
$target = $filename . $itemNumber . "." . $extension;


// Place file on server, into the images folder
move_uploaded_file($_FILES['Filedata']['tmp_name'], "images/".$target);



This works perfect, but what I want to change is the width and height of the uploaded image.
Any ideas/suggestions on how this could be done?

Thanks in advance!!
Cheers!

OK,

When the user fills the info in the form out it goes in the DB fine.  I can then array them on the "showroom page" fine.

When they upload a picture it goes into the /images/ folder fine.

Problem is... On each array on the showroom page I need the image they uploaded to be displayed.

Cant work it out.

Help would be GREAT!!!!!

hi to all.Im currently displaying the images from my upload directory but the image does not display.please help thanks

Hi

Basically I've built a CMS where by my clients can upload a number of images. On the success page I want to display the images they uploaded by file name.

The issue is the number of images can vary. They may upload 2 or 10 or 50 etc.

So far I've come up with this:

Code: [Select]
// number of files
$UN = 3; //I've set this to 3 for now, but this is passed from the upload page!

// server directories and directory names
$dir = '../properties';

$images = glob($dir.'/*.{jpg}', GLOB_BRACE); //formats to look for

$num_of_files = $UN; //number of images to display from number of uploaded files

foreach($images as $image)
{
$num_of_files--;

$newest_mtime = 0;
$image = 'BROKEN';
if ($handle = @opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if (($file != '.') && ($file != '..')) {
$mtime = filemtime("$dir/$file");
if ($mtime > $newest_mtime) {
$newest_mtime = $mtime;
$image = "$file";
}
}
}
}

if($num_of_files > -1) //this made me laugh when I wrote it
echo $trimmed = ltrim($image, "../properties").'<br />'; //display images
else
break;
}
Without this piece of code:

Code: [Select]
$newest_mtime = 0;
$image = 'BROKEN';
if ($handle = @opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if (($file != '.') && ($file != '..')) {
$mtime = filemtime("$dir/$file");
if ($mtime > $newest_mtime) {
$newest_mtime = $mtime;
$image = "$file";
}
}
}
}
It shows the first 3 files alphabetically. I want to view the last number of images added.

With the above code it simply shows the last image added 3 times!

So I need to get the time each image was added and then order by the newest added and limit to the number of images uploaded. Any suggestions please?

Kindest regards
Glynn

Hey guys,

I am making a quotes siggy, code:
<?php

/**
 * @author Jragon
 * @copyright 2010
 */

$textfile = "quotes.txt";
$quotes = array();
if (file_exists($textfile)) {
    $quotes = explode("\n", file_get_contents($textfile));
    srand((float)microtime() * 10000000);
    $string = $quotes[array_rand($quotes)];
    $string = wordwrap($string, 100, "\n", true);
    text_to_image($string, 800);
} else {
    $string = "Sig file non-existant...";
}
function text_to_image($text, $image_width, $colour = array(0, 244, 34), $background =
    array(0, 0, 0))
{
    $font = 5;
    $line_height = 15;
    $padding = 2;
    $text = wordwrap($text, ($image_width/10));
    $lines = explode("\n", $text);
    $image = imagecreate($image_width, ((count($lines) * $line_height)) + ($padding *
        2));
    $background = imagecolorallocate($image, $background[48], $background[44], $background[44]);
    $colour = imagecolorallocate($image, $colour[0], $colour[1], $colour[2]);
    imagefill($image, 0, 0, $background);
    $i = $padding;
    foreach ($lines as $line) {
        imagestring($image, $font, $padding, $i, trim($line), $colour);
        $i += $line_height;
    }
    header("Content-type: image/jpeg");
    imagejpeg($image);
    imagedestroy($image);
    exit;
}
?>


What i want it to do is have the lines the same legnth, and when a quote is smaller the image to shrink.


Thanks

I need help making the uploaded image file name, that's chosen to be uploaded, be displayed on the html page with the path /upload/ added to the beginning of the displayed file name like so:
../upload/test.png
Any help/improvements will be appreciated.

<html>
 <head>
  <title>PHP Test</title>
 </head>
  <body>
 <?php
 if ($form_submitted == 'yes') {
 $allowedExts = array("gif", "jpeg", "jpg", "png");
 $temp = explode(".", $_FILES["file"]["name"]);
 $extension = strtolower( end($temp) );
 if (  $_FILES["file"]["size"] < 200000
       && in_array($extension, $allowedExts) )
 {
     if ($_FILES["file"]["error"]!= 0)
     {
         echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
     } else {
         $length = 20;
         move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $newfilename );
         $file_location = '<a href="http://../upload/' . $newfilename . '">' . $newfilename . '</a>';
     }
 } else {
   echo "Invalid upload file";
 }
?>
<label for="file">Filename:</label>
<input type="file" name="file" id="file">
</body>
</html>

Hey everyone. I have been trying to make a script that allows me to resize an image but I am having some trouble. I have got a script that takes  an image and resize's it:
Code: [Select]
<?php 
 $save = $_REQUEST['SavedAs'] ;
 $file = $_REQUEST['ImgAdd'] ;
 echo "Creating file: $save"; 
 $size = 0.45; 
 header('Content-type: image/jpeg') ; 
 list($width, $height) = getimagesize($file) ; 
 $modwidth = 240; 
 $modheight = 180; 
 $tn = imagecreatetruecolor($modwidth, $modheight) ; 
 $image = imagecreatefromjpeg($file) ; 
 imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width, $height) ; 
 
 imagejpeg($tn, $save, 100) ; 
 
 header ("Location: $save");
 ?>
But depending on the image, the aspect ratio looks wrong. Is there anyway to take an image, crop it, then resize it? Or something that makes it look decent?

Thanks

Sorry bit rusty but been trying this for hours I upload an image no errors are showing i upload a jpg file and it saves to the server fine but its saving the original size not the new resized image size any ideas??

Code: [Select]


if (isset ($_FILES['file'])) {

$tmp_name = $_FILES["file"]["tmp_name"];
                  $file_type = $_FILES["file"]["type"];
$fileatt_name = $_FILES["file"]["name"];

if ($file_type=="image/pjpeg" OR $file_type=="image/jpeg" OR $file_type=="image/jpg")
{
$src = imagecreatefromjpeg($tmp_name);
} // END if ($file_type=="image/pjpeg" OR $file_type=="image/jpeg" OR $file_type=="image/jpg")

if ($file_type=="image/png" OR $file_type=="image/x-png")
{
$src = imagecreatefrompng($tmp_name);
} // END if ($file_type=="image/png" OR $file_type=="image/x-png")

if ($file_type=="image/gif")
{
$src = imagecreatefromgif($tmp_name);
} // END if ($file_type=="image/gif")

list($width,$height)=getimagesize($tmp_name);
$width = $width;
$height = $height;
$newwidth = "200";
$newheight = "200";
$ratio='';

if($width==$height)
{
$newwidth = "200";
$newheight = "200";
}

if($width>$height)
{
$ratio=($height/$width);
$newwidth = "200";
$newheight = ($newwidth*$ratio);
}

if($width<$height)
{
$ratio=($width/$height);
$newheight = "200";
$newwidth = ($newheight*$ratio);
}

$tmp = imagecreatetruecolor($newwidth, $newheight);
$new=imagecopyresampled($tmp, $src,0,0,0,0,$newwidth,$newheight,$width,$height);
$filename = "./yxy/". $fileattt_name;
imagejpeg($tmp,$filename,100);   
imagedestroy($tmp);

}

As a point of curiosity, I am seeking some clarification.

I have developed code to resize an image, thus reducing the file size by a percentage of it's original.

My first question is, what exactly is being done to the file?

I understand that some data is being removed (or condenced) but how does this effect the image when compared with the original on a webpage?

Next, what should my expectation be if I wanted to reverse the process?

If I am 'shrinking' an image for a faster upload speed and reduced storage capacity, how successful will I be if I wanted to 'restore' the file size before printing a physical photograph?  Will this provide a 'better' end result?

 

Hello:

I have a photo uploader in my admin area. First time I tried this so it's new to me. The upload form sends it to the page below, and does the resizing and saving.

It seems to automatically resize the photos to make thumbnails, which is really nice.

However, I am trying to do 2 things and can't figure it out.

1 - I would like to resize the main photo and not the thumbnail (or just use the thumbnail as the main photo, whichever seems easier).
I would like it to be 690px wide but let it scale in proportion to what the height should be (not set a height as I think that's what it is doing now).

This is the area where it gets resized:
Code: [Select]
{
$thumbnail_width = 690;
$thumbnail_height = (int)(100 * $size[1] / $size[0]);
}
else
{
$thumbnail_width = (int)(690 * $size[0] / $size[1]);
$thumbnail_height = 100;
}


Also, the thumbnails are coming out very dark and de-colored. How can I set it so it retains all the color and clarity, but just resizes them?

Point I'm trying to do is just resize upon upload, as most of my clients do not and will not resize photos before uploading them, and that means each photo from a digital camera will be about 1.3 MBs, which starts to make a photo gallery page very heavy and clunky.

This is the full code, if it will help:
Code: [Select]
<?php
// initialization

Hi all

I am trying to write a piece of code that will resize and image to fit in a canvas 300 by 300 pixels and centre horizontally and vertically. Here's my code:

Code: [Select]
$imagelarge = $_FILES['image']['tmp_name'];
$imagelargemain = $_FILES['image']['name'];
$src = imagecreatefromjpeg($imagelarge);
list($width,$height)=getimagesize($imagelarge);
$newwidth=300;
$newheight=($height/$width)*$newwidth;
$center_x = 300/300;
$center_y = (300/2)-($newheight/2);
$tmp=imagecreatetruecolor(300,300);
$white = imagecolorallocate($tmp, 255, 255, 255);
imagefill($tmp, 0, 0, $white);
imagecopyresampled($tmp,$src,$center_x,$center_y,0,0,$newwidth,$newheight,$width,$height);

This works ok but if the user uploads a very thin and tall image it only shows the middle?

Please help!

Many thanks
Pete

i have a script that uses simple file function to upload images.. is der a way i can sumhow select multiple files and use them to upload.. or is there a way i can resize or reduced the size of the image as its being uploaded.. if yes please guide me through!

i use simple form to upload the file and use the following file to upload

move_uploaded_file($_FILES['img']['tmp_name'], "images/albums/{$_FILES['img']['name']}");

Having a nightmare here lol

$img->set_size(225);

That is resizing the image with a maximum width but i need to resize it to make it have a maximum height but can't figure out how to do it

Here's my full code if you want to see it:

Code: [Select]
<?php
include("class.imaging.php");

// The file
$dir = "upload/";
$file = $newfile;
$filename = $dir . $file;


$img = new imaging;
$img->set_img($filename);
$img->set_quality(120);

// Profile Picture
$img->set_size(225);
$img->save_img("upload/thumb/" . $file);

$img->clear_cache();
?>
