PHP - Resize And Image Before Upload

I am VERY new to PHP, but I am trying to adapt code from http://www.4wordsystems.com/php_image_resize.php to work with multiple images.  Can any please help?

I know I need to place it in a loop of some kind, but I don't know how to write the code for that.  Here is the code:

HTML FORM CODE:
Code: [Select]
<form action="upload.php" method="post" enctype="multipart/form-data" >
<input type="file" name="uploadfile"/>
<input type="submit"/>
</form>
upload.php CODE:
Code: [Select]
<?php

// This is the temporary file created by PHP
$uploadedfile = $_FILES['uploadfile']['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);

// For our purposes, I have resized the image to be
// 600 pixels wide, and maintain the original aspect
// ratio. This prevents the image from being "stretched"
// or "squashed". If you prefer some max width other than
// 600, simply change the $newwidth variable
$newwidth=600;
$newheight=($height/$width)*600;
$tmp=imagecreatetruecolor($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.
$filename = "images/". $_FILES['uploadfile']['name'];
imagejpeg($tmp,$filename,100);

// For our purposes, I have resized the image to be
// 150 pixels high, and maintain the original aspect
// ratio. This prevents the image from being "stretched"
// or "squashed". If you prefer some max height other than
// 150, simply change the $newheight variable
$newheight=150;
$newwidth=($width/$height)*150;
$tmp=imagecreatetruecolor($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.
$filename = "images/thumb_". $_FILES['uploadfile']['name'];
imagejpeg($tmp,$filename,100);

imagedestroy($src);
imagedestroy($tmp); // NOTE: PHP will clean up the temp file it created when the request
// has completed.

echo "Successfully Uploaded: <img src='".$filename."'>";

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.

below is my working code:

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

When i use the following script to upload and resize an image, it throws out errors (see after script)
<?php 
$image = $_FILES['image']['name'];
 
    
    $uploaddir = "./images/$gender/";
    
    $pext = getExtension($image);
    $pext = strtolower($pext);
    if (($pext != "jpg")  && ($pext != "jpeg") && ($pext != "gif"))
    {
        print "<h1>ERROR</h1>Image Extension Unknown.<br>";
        print "<p>Please upload only an image with the extension .jpg or .jpeg or .gif ONLY<br><br>";
        print "The file you uploaded had the following extension: $pext</p>\n";

        unlink($imgfile);
        exit();
    }


    $imgsize = GetImageSize($image);

    /*== check size  0=width, 1=height ==*/
    if (($imgsize[0] > 460) || ($imgsize[1] > 345)) 
    {
        $tmpimg = tempnam("/tmp", "MKUP");

        system("djpeg $image >$tmpimg");
        
        system("pnmscale -xy 250 200 $tmpimg | cjpeg -smoo 10 -qual 50 >$imgfile");

        unlink($tmpimg);

    }

$rand = rand(0,9999999);
$date = DATE("d.m.y");
$image_name=$date.$id.$rand.'.'.$extension;
$final_filename = str_replace(" ", "_", $image_name);
$newfile = $uploaddir . "/$final_filename";
    
    if (is_uploaded_file($image))
    {

       if (!copy($imgfile,"$newfile")) 
       {
          print "Error Uploading File.";
          exit();
       }
     }
    unlink($image);

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?

Hi,

I'm having to look hard for the right way to do this.

Basically the image is sent to the database, and is called to be put in a table, but the images are all different sizes, i would like them all one size, whats the best way to do this with my existing 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("***", "***", "***") or die(mysql_error()) ; 
 mysql_select_db("***") 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."; 
 } 
 ?>

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.
