PHP - Simple Image Upload And Resize

I am working on an uploader and slowly getting it working, I am uploading 3 images at once, and setting arrays for each one as keys, with an increment of ++1. I am wanting to resize the image before it gets copied to the thumbnail folder.

I have this code.

<?php

if (isset($_POST['addpart'])) {


    $image = $_FILES['images']['tmp_name'];

    $name  = $_POST['username'];

    $i     = 0;

    foreach ($image as $key) {


        $fileData   = pathinfo(basename($_FILES["images"]["name"][$i]));

        $fileName[] = $name . '_' . uniqid() . '.' . $fileData['extension'];

        move_uploaded_file($key, "image/" . end($fileName));


    //get uploaded file info before we proceed with resize

    $image_name = $_FILES['images']['name'][$i]; //file name

    $image_size = $_FILES['images']['size'][$i]; //file size

    $image_temp = $_FILES['images']['tmp_name'][$i]; //file temp

    $image_size_info    = getimagesize($image_temp); //gets image size info from valid image file



        copy("image/" . end($fileName), "image_thumbnail/" . end($fileName));

        $i++;

    }

    echo 'Uploaded<br>';

    echo 'Main Image - ' . $fileName[0] . '<br>';

    echo 'Extra Image 1 - ' . $fileName[1] . '<br>';

    echo 'Extra Image 2 - ' . $fileName[2] . '<br>';

    echo '<hr>';


}

?>

Everything works with it. As you see, I started on getting the file info, but after that I am totally stuck on what to do after to resize the image proportionally with a maximum width of xPX and height to match it without looking distorted.

Any help would be really appreciated. Thank You.

Okay, so I found this code on-line that uploads images via a form, inserts them in to MySQL and displays the images on the page.  It works great!  Problem is, I spent a long time hacking this script to make it work with my site just to realize it did not re-size the image after it uploaded (dumb me).  I have found other code that do this but I really do not want to start over at this point and my level of expertise with PHP are a step below what I need to figure this out.  I am attaching the "original" code.  If anyone knows how to add the necessary lines of code to make every image re-size (reduce) itself.  I would very much appreciate it.  Thanks

I have a working image upload script that uploads, renames the file and adds filename to the database.

is it possible to include some sort of image resize code? if so can anyone point me in the right direction or better still show some example code and explain how it works etc.

Many thanks to phpfreaks again.

Hi,

Im rather new to php and really unable to get the above to work. Everything works apart from the image being resized. File is uploaded, and the image name is printed into the SQL database. But i cant for the life of me get the image to go to 300x200? If you could help me i would be very grateful

My code for the form processing page is attached. Ive put a few line breaks into the code as to where i think is the issue. I just cant seem to resize the image. Does the image resize need to come before the part it writes the image to the server or can this be done afterwards? Please help.

P.S - Thanks in advance

I have code written for image uploading, but it doesn't allow multiple images on a single upload, and doesn't re-size.

Anyone willing to share a good upload script that will do the following?:
-Allow multiple image uploads (10+ per submission),
-Re-size images on upload, and
-Rename images.

Thanks
Brett

Hi Guys

I'm trying to get clients to:
1. upload an image
2. fill out details
3. submit image and details to me via email

1. Uploading the image is fine, they choose it and it displays on the next page
2. They fill in form details
3. then click submit to send to me - I get all details except the image

How do I keep the image variable around to insert it into the details form and email it?

The image appears to be displayed on the second page, then the variable disappears (is deleted) and isn't available in step 3 to submit as part of the email.

I'm sure it's a simple fix - I'm pretty new with php and I've started kicking things so I thought it was time to ask for help.

Upload-image-code

<?php if($_FILES)
{ 
$img = $_FILES['filename']['img'];

switch($_FILES['filename']['type'])
{
case 'image/jpeg' : $ext = 'jpg'; break;
case 'image/png' : $ext = 'png'; break;
default: $ext = ''; break;
}
if ($ext)
{
$n = "image.$ext";
move_uploaded_file($_FILES['filename']['tmp_name'], $n);
echo "<span class='uploaded-photo'>uploaded image '$img'  as '$n':</span> <br />";
echo "<img src='$n' />";
}
else echo "'$img' is not a supported image file";
}
//else echo "<span class='uploaded-photo'>No image has been uploaded</span>";

 ?>

$n is available to be displayed on page 2 and it works
Page 2 contains the rest of the form, but when I submit the form $n isn't available to be sent with the other data
(i have tried REQUEST $img as well.
Submit form code

<?php
$name = $_REQUEST['name'] ;
$email = $_REQUEST['email'] ;
$phone = $_REQUEST['phone'] ;

$pname = $_REQUEST['pname'] ;
$pdescription = $_REQUEST['pdescription'];

$purl = $_REQUEST['purl'] ;
$ponline = $_REQUEST['ponline'] ;
$n = $_REQUEST['n'];
$img = $_REQUEST['img'];


if (!isset($_REQUEST['email'])) {
    echo "we need your name and email address please" ;
  }

elseif (empty($name)){
echo "please enter your name";
}
elseif (empty($email)){
echo "please enter your email address";
}
elseif (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,6})", "$email")) {
echo"please check your email address - it doesn't appear to be a valid format";
}
else {
    mail( "eamail@address.com", "Subject",
     "$name\n $email\n $phone\n $address\n $pname\n $pdescription\n $plow\n $phigh\n $purl\n $ponline\n $n\n $img", "$email");
   
    header( "Location: ../index.php" );
  }


?>

Would really appreciate any help - if you need full code please let me know.

Thanks

Alright guys, i have been looking for a simple script for this online to try get my head around it. I need a script thats is going to take an image and save the orginal file along with two modified files (small and medium thumbnail). I really cant get my head around the ones i have already seen so i was wondering if anyone had any advice or a link they can post me to that can help me.

Hi!

I'm looking for a script that can do the following:

upload one or preferably fx. five image files(jpg)

resizes them to a specific size if they exceeds that size.

create a thumbnail

No files above 100kb can be uploaded.

uploaded and/or processed files must be renamed with a unique file name.

Work with php5


I have searched the internet for a script like that, but I can't find one that matches my needs. Also, the code must include good comments and nott be to hard to understand. So as basic code as possible.

I want to reduce a picture size from 600px * 500px to 60px * 50px size, then crop it become 50px *50px. I have two groups of codes, 1 is to reduce the size of image, other 1 is to crop the image. The problem is they works separately, how to combine this two groups of codes to make them work together? Below is my codes :

Code: [Select]
<?php
//codes of group A - Reduce the size of image from 600px * 500px to 60px * 50px   
    $save2 = "images/users/" . $image_name_2; //This is the new file you saving
    list($width2, $height2) = getimagesize($file) ; 
    $modwidth2 = 50; 
    $diff2 = $width2 / $modwidth2;
    $modheight2 = $height2 / $diff2; 
    $tn2 = imagecreatetruecolor($modwidth2, $modheight2) ; 
    $image2 = imagecreatefromjpeg($file) ; 
    imagecopyresampled($tn2, $image2, 0, 0, 0, 0, $modwidth2, $modheight2, $width2, $height2) ; 
    imagejpeg($tn2, $save2, 100) ; 

//codes of group B - Crop the image from 60px * 50px to 50px * 50px 
    $save3 = "images/users/" . $image_name_3;  
    list($width3, $height3) = getimagesize($file) ; 
    $modwidth3 = 60;  
    $diff3 = $width3 / $modwidth3;
    $modheight3 = $height3 / $diff3; 

    $left = 0; 
    $top = 0;

    $cropwidth = 50; //thumb size
    $cropheight = 50;

    $tn3 = imagecreatetruecolor($cropwidth, $cropheight) ; 
    $image3 = imagecreatefromjpeg($file) ; 
    imagecopyresampled($tn3, $image3, 0, 0, $left, $top, $cropwidth, $cropheight, $modwidth3, $modheight3) ; 
    imagejpeg($tn3, $save3, 100) ; //save the cropped image
?>
As you can see from 2 groups of codes above, 1st group resize the pic then save it to a folder. 2nd group of codes crop the pic then save it into the folder too. My question is ... After 1st group of codes resize the picture, is it necessary to save it into folder before I can crop it? If it is necessary, then I need to write new lines of codes to retrieve the resized pic from the folder for 2nd group of codes to crop it? If it is not necessary, after resizing the pic, how do I pass the pic to 2nd group of codes to crop it?
php image-resizing

The below code inserts image details to db and uploads pic to folder, can anyone show me how to resize it aswell. please

Code: [Select]
<?php
include("includes/connection.php");

I did a tutorial on uploading a profile pic and also did a tutorial on an image re-size class. The only thing is the tutorial on the re-size class is done without using a form which is pointless. Can someone help me integrate this into the profile pic tutorial? Here's a link to the re-size tutorial.

hello
I want download a file from another website and resize it to new size then reduce quality to 60% and save in on my host.
this is my code about download and reduce quality.
//images address
$images1 = textbetween('<a href="','"',$text0);
//save images
$im = imagecreatefromjpeg($images1); // original image
//reduce image quality
imagejpeg($im, "/public_html/static/images/book/".$imagename.".jpg" , 60); // save to new image, third value is quality (0-100) if not specified its the default (75)
can anyone help me to resize it?


thank you

I am looking for a script that can change the width and height of an image when it is uploaded to our web site through a web form. Any help would be great.
