PHP - Resizing Uploaded Images

Hi everyone,

I am after a scrpit/function that will get information of an uploaded image, resize it, then display the manipulated image.

in my "upload" script, there will be a size limit and a file extension/type limit to:  600 x 200px / jpg, gif, jpeg... this is to keep the script i'm after more simple. As using vector images i'm told is such a complicated problem for me at this time.

So...

to get the size info/dimensions its like this:


Code: [Select]
<?php

list($width, $height, $type, $attr) = getimagesize("image_name.jpg");

echo "Image width " .$width;
echo "<BR>";
echo "Image height " .$height;
echo "<BR>";
echo "Image type " .$type;
echo "<BR>";
echo "Attribute " .$attr;

?>

and..... resize something like this:

Code: [Select]
function get_image_sizes($sourceImageFilePath,
  $maxResizeWidth, $maxResizeHeight) {

  // Get width and height of original image
  $size = getimagesize($sourceImageFilePath);
  if($size === FALSE) return FALSE; // Error
  $origWidth = $size[0];
  $origHeight = $size[1];

  // Change dimensions to fit maximum width and height
  $resizedWidth = $origWidth;
  $resizedHeight = $origHeight;
  if($resizedWidth > $maxResizeWidth) {
    $aspectRatio = $maxResizeWidth / $resizedWidth;
    $resizedWidth = round($aspectRatio * $resizedWidth);
    $resizedHeight = round($aspectRatio * $resizedHeight);
  }
  if($resizedHeight > $maxResizeHeight) {
    $aspectRatio = $maxResizeHeight / $resizedHeight;
    $resizedWidth = round($aspectRatio * $resizedWidth);
    $resizedHeight = round($aspectRatio * $resizedHeight);
  }
 
  // Return an array with the original and resized dimensions
  return array($origWidth, $origHeight, $resizedWidth,
    $resizedHeight);
}

// Get dimensions
$sizes = get_image_sizes($sourceImageFilePath, $maxResizeWidth,
  $maxResizeHeight);
$origWidth = $sizes[0];
$origHeight = $sizes[1];
$resizedWidth = $sizes[2];
$resizedHeight = $sizes[3];

// Create the resized image
$imageOutput = imagecreatetruecolor($resizedWidth,
    $resizedHeight);
if($imageOutput === FALSE) return FALSE; // Error condition

// Load the source image
$imageSource = imagecreatefromjpeg($sourceImageFilePath);
if($imageSource === FALSE) return FALSE; // Error condition

$result = imagecopyresampled($imageOutput, $imageSource,
    0, 0, 0, 0, $resizedWidth, $resizedHeight, $origWidth,
    $origHeight);
if($result === FALSE) return false; // Error condition

// Write out the JPEG file with the highest quality value
$result = imagejpeg($imageOutput, $outputPath, 100);
if($result === FALSE) return false; // Error condition




And.... display is this:

Code: [Select]
<?php 
$database="***"; 
mysql_connect ("***", "***", "***"); 
@mysql_select_db($database) or die( "Unable to select database"); 
$result = mysql_query( "SELECT company_name, location, postcode, basicpackage_description, premiumuser_description, upload FROM Companies" ) 
or die("SELECT Error: ".mysql_error()); 
$num_rows = mysql_num_rows($result); 
print "\n\n\nThere are $num_rows records.<P>"; 
echo "<table><tr><th>Comppany Name</th><th>Location</th><th>Postcode</th><th>Basic Members</th><th>Upgraded Users</th><th>Company Logo</th></tr><tr><td></td><td></td><td></td><td></td><td></td><td></td></tr>";// store the records into $row array and loop through 
while ( $row = mysql_fetch_array( 
$result, MYSQL_ASSOC ) ) {
// Print out the contents of the entry  
echo "<tr><td>{$row['company_name']}</td>";
echo "<td>{$row['location']}</td>"; 
echo "<td>{$row['postcode']}</td>"; 
echo "<td>{$row['basicpackage_description']}</td>"; 
echo "<td>{$row['premiumuser_description']}</td>"; 

echo "<td><img src=\"http://www.removalspace.com/images/COMPANIES{$row['upload']}\" alt=\"logo\" /></td></tr>";} 
echo "</table>";
?>



How will all these fit together in one script?  any help i'd love it! many thanks in advance

Hi all,

Could someone help me add a thumbnail script to the below that works on scaling it down to 200px x 133px.

I guess it is not that hard.


<?php
$destination='aircraft/'.$reg."1.jpg";
$temp_file = $_FILES['image']['tmp_name'];
move_uploaded_file($temp_file,$destination);
?>


Thanks

Upload images - Thumbnail sizes?

Hi all

I haven't used php for a while now and I'm really stuck on some code I wrote and now I can't work how to change it.

I have this function to upload images and create thumbnails. The thumbnails can be either landscape or portrait and I want them to have the same height. At the moment the portrait thumbnails height is equal to the landscape thumbnail width. The dimensions of the thumbnails are the same but the portrait images are portrait.

How can I size the thumbnails so they all have the same height. 

Thanks in advance for any help or advice on this.

Right now users log in and upload an image to the website.  I want every image that is uploaded to be watermarked with a particular logo.  Is this possible? Any hints or tips will be appreciated. Thank you.

Is it better to store uploaded images as 'content' in the database? (like he http://www.techsupportforum.com/forums/f49/tutorial-upload-files-to-database-176804.html).. Or just as a regular file which is referenced in the database..?

Hi, this is what I want to get working: each time I add an entry, it is displayed in a nice html table, and each entry listed in this html table has an UPDATE link that allows the user to update the Price and Description field of the corresponding table in my database. I have also included an upload element which whenever a user chooses an image, it will replace the default fileUploadIcon.jpg with this. Please see the index.php and bellUpdateForm.php below respectively

Hi, I have a pretty simple application that allows my users to upload images and i'm able to succesfull upload images to a new dir to be outputted.  But as to save on download time and server space is there a simple piece of code I can add to the below code that will resize every image on uploded to 460(w) x 300 (h) from my users

Code: [Select]
<?php
if ((($_FILES["article_image"]["type"] == "image/gif")
|| ($_FILES["article_image"]["type"] == "image/jpeg")
|| ($_FILES["article_image"]["type"] == "image/pjpeg"))
&& ($_FILES["article_image"]["size"] < 5000000))
  {

      move_uploaded_file($_FILES["article_image"]["tmp_name"],
      "images/" . $_FILES["article_image"]["name"]);
      }

?>

Thanks in advance for any help and suggestions

I am absolutley stumped with this:

im trying to have PHP get the size of an image that has been uploaded to mySQL, and return it to a certain size, lets say 200X200px.

The problems im having to finding an existing script to help me understand - and then fit it into a table?


All the help from google searches seem to suggest using software, but i would like to learn how to do this properly.


First off the upload script:

Code: [Select]
<?php 
 error_reporting(E_ALL);
 ini_set("display_errors", 1);
 echo '<pre>' . print_r($_FILES, true) . '</pre>';

 
 //This is the directory where images will be saved 
 $target = "/home/users/web/b109/ipg.removalspacecom/images/COMPANIES"; 
 $target = $target . basename( $_FILES['upload']['name']); 
 
 //This gets all the other information from the form 
 $company_name=$_POST['company_name']; 
 $basicpackage_description=$_POST['basicpackage_description']; 
 $location=$_POST['location']; 
 $postcode=$_POST['postcode'];
 $upload=($_FILES['upload']['name']); 
 
 // Connects to your Database 
 mysql_connect("server", "user", "password") or die(mysql_error()) ; 
 mysql_select_db("removalspacelogin") or die(mysql_error()) ; 
 
 //Writes the information to the database 
 mysql_query("INSERT INTO `Companies` (company_name, basicpackage_description, location, postcode,  upload) VALUES ('$company_name', '$basicpackage_description', '$location', '$postcode',  '$upload')") ; 
 echo mysql_error();
 
 //Writes the photo to the server 
 if(move_uploaded_file($_FILES['upload']['tmp_name'], $target)) 
 { 
 
 //Tells you if its all ok 
 echo "The file ". basename( $_FILES['upload']['name']). " has been uploaded, and your information has been added to the directory"; 
 } 
 else { 
 
 //Gives and error if its not 
 echo "Sorry, there was a problem uploading your file."; 
 } 
 ?>

this works great, it uploads the users pictures.

This displays them out:

Code: [Select]
<?php 
$database="removalspacelogin"; 
mysql_connect ("server", "user", "password"); 
@mysql_select_db($database) or die( "Unable to select database"); 
$result = mysql_query( "SELECT company_name, location, postcode, basicpackage_description, premiumuser_description, upload FROM Companies" ) 
or die("SELECT Error: ".mysql_error()); 
$num_rows = mysql_num_rows($result); 
print "\n\n\nThere are $num_rows records.<P>"; 
echo "<table><tr><th>Comppany Name</th><th>Location</th><th>Postcode</th><th>Basic Members</th><th>Upgraded Users</th><th>Company Logo</th></tr><tr><td></td><td></td><td></td><td></td><td></td><td></td></tr>";// store the records into $row array and loop through 
while ( $row = mysql_fetch_array( $result, MYSQL_ASSOC ) ) {
// Print out the contents of the entry  
echo "<tr><td>{$row['company_name']}</td>";
echo "<td>{$row['location']}</td>"; 
echo "<td>{$row['postcode']}</td>"; 
echo "<td>{$row['basicpackage_description']}</td>"; 
echo "<td>{$row['premiumuser_description']}</td>"; 

echo "<td><img src=\"http://www.removalspace.com/images/COMPANIES{$row['upload']}\" alt=\"logo\" /></td></tr>";} 
echo "</table>";
?>

Right now all the information in my table is fine except the image coloumn, the images are all the same size as they went in, i'd like them to all be one size so there in a uniformed fashion. But need all the rest of the mySQL table displayed, so how does it fit into my script to display the table? Many thanks!??? 

I am using Amazon's S3 service to allow users to upload images.   Since you have to pay for this service, my plan was to resize all uploaded images (maybe to a max of 200 pixels wide or something) immediately before sending them to Amazon.

I googled this and only thing I found said that "resizing on the fly is slow and expensive because disk space is cheaper than CPU."  Is this accurate?

Anyone have any thoughts on this?  I feel like I have to restrict the size of images some way because I don't wan't people uploading huge 2000x2000 images.

In case it matters, below is some code I have used below for resizing (albeit on my own server), so I imagine I'll use something similar for this new project which ultimately sends the image to Amazon.

Code: [Select]
// This is the temporary file created by PHP
$uploadedfile = $_FILES['userfile']['tmp_name'];

// Create an Image from it so we can do the resize
$src = imagecreatefromjpeg($uploadedfile);

// Capture the original size of the uploaded image
list($width,$height) = getimagesize($uploadedfile);

$newheight=70;
$newwidth= 70;

$tmp=imagecreatetruecolor($newwidth,$newheight);

// this line actually does the image resizing, copying from the original
// image into the $tmp image

imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);

// now write the resized image to disk. I have assumed that you want the
// resized, uploaded image file to reside in the ./images subdirectory.

$imagefolder = 'images/userimages/user' . $_SESSION['userid'] . '.jpg';
$filename = $imagefolder;
$_SESSION['filename'] = $filename;
if (imagejpeg($tmp,$imagefolder,100)) {
$imagemessage = "File is valid, and was successfully uploaded into FOLDER.\n";
$success="yes";
} else {
$imagemessage = "Possible file upload attack!\n";
$success="no";
}
imagedestroy($src);
imagedestroy($tmp); // NOTE: PHP will clean up the temp file it created when the request
// has completed.

}

Any help would be appreciated.

I am looking to resize images from a database and found this guide.  It looks relatively simple.  Is this the easiest method of resizing images.

Hi I'm trying to setup Pagination at the bottom of the page after showing 10 images in the following script but have no clue where to start and how to implement it into the script. 

I am trying to upload files to a user profile system.
here is the profile page

Code: [Select]
<?php

include('core/init.inc.php');

if (isset($_POST['email'], $_POST['location'], $_POST['about']))
{
$errors = array();

if(filter_var($_POST['email'], FILTER_VALIDATE_EMAIL) === false)

{
$errors[] = "The email address you entered is not valid";
}

if(preg_match('#^[a-z0-9 ]+$#i',$_POST['location'])===0)
{
$errors[] = 'Your location must only contain A-Z 0-9 and spaces.';
}

if (empty($_FILES['avatar']['tmp_name']) === false)
{
$file_ext = end(explode('.', $_FILES['avatar']['name']));

if(in_array(strtolower($file_ext), array('jpg', 'jpeg', 'gif', 'png')) === false)
{
$errors[] = 'Your avatar must be an image.';
}
}
if(empty($errors))
{
print_r($_FILES);
set_profile_info($_POST['email'],$_POST['location'],$_POST['about'], (empty($_FILES['avatar']['tmp_name'])) ? false : $_FILES['avatar']['tmp_name']);
}

$userinfo = array(
'email' => htmlentities($_POST['email']),
'location' => htmlentities($_POST['location']),
'about' => htmlentities($_POST['about'])
);

}

else
{
$userinfo = fetch_user_info($_SESSION['uid']);

                        WHERE `user_id` = {$_SESSION['uid']}";
       
        mysql_query($sql);
       
}

Below I have returned the array of files to check if its been uploaded correctly.
Array ( [avatar] => Array ( [name] => Sonic.jpg [type] => image/jpeg [tmp_name] => /var/tmp/php.waq8n [error] => 0 [size] => 48477 ) )

But I get this error message.
Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: '/var/tmp/php.waq8n' is not a valid JPEG file in /web/stud/u0963643/userprofilesection/finaluserprofile/core/inc/user.inc.php on line 71

If someone could point out where in this code I have made an error I would be very grateful

Thanks

Hello,

I have a form for uploading CV files into a CV database.

Once the files are uploaded to their directory (e.g. www.jobsboard.com/cvdatabase/) please could someone tell me how to restrict access to users?

e.g. once a user logs into their userpanel they should be able to click on a hyperlink to download a CV e.g. (www.jobsboard.com/cvdatabase/CV1.doc) but a user who isn't logged in shouldn't be able to access www.jobsboard.com/cvdatabase/CV1.doc

Please could you tell me whether this is possible?

Many thanks,

Stu
