I am trying to simplify it to work I keep on getting errors and I don't know why?

 

Code is as follows

 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>

<body>
<form  method="post" action="upload.php" enctype="multipart/form-data">
    <input type="file" name="photos[]"><br />
    <input type="file" name="photos[]"><br />
    <input type="file" name="photos[]"><br />
    <input type="submit" value="Upload" />
</form>
</body>
</html>

 

upload.php

 

<?php

foreach ($_FILES[photos][name] as $key => $value) {
       $uploadfile = $uploaddir . basename($_FILES['photos']['name'][$key]);

// This is the temporary file created by PHP
$uploadedfile = $_FILES['photos']['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/". $_FILES['photos']['name'];
imagejpeg($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_". $_FILES['photos']['name'];
imagejpeg($tmp,$filename,100);

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

       //echo $uploadedfile;
       if (move_uploaded_file($_FILES['photos']['tmp_name'][$key], $uploadedfile)) { echo $value . ' uploaded<br>'; }
}

?>

 

 

Then  there are my errors

Try this, fixed an obvious issue, and added some checking to make sure that the getimgsize actually works.

 

foreach($_FILES['new_image'] as $image) {
              $imagename = $image['name'];
              $source = $image['tmp_name'];
              $target = "photos/".$imagename;
              move_uploaded_file($source, $target);

              $imagepath = $imagename;
              $save = "photos/" . $imagepath; //This is the new file you saving
              $file = "photos/" . $imagepath; //This is the original file

              $modheight = 350; 
              $imgsize = getimagesize($file);
              if ($imgsize !== false) { 
                      $width = $imgsize[0];
                      $height = $imgsize[1];
                      $diff = $height / $modheight;
                      $diff = ($diff) > 0 : $diff ? 1;                      
                      $modwidth = $width / $diff; 
                      $tn = imagecreatetruecolor($modwidth, $modheight) ; 
                      $image = imagecreatefromjpeg($file) ; 
                      imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width, $height) ; 
                      imagejpeg($tn, $save, 100) ;  
                      $save = "photos/thumbs/" . $imagepath; //This is the new file you saving
                      $file = "photos/" . $imagepath; //This is the original file
                      list($width, $height) = getimagesize($file) ; 

                      $modheight = 100;  
                      $diff = $height / $modheight;
                      $diff = ($diff) > 0 : $diff ? 1;        
                      $modwidth = $width / $diff; 
                      $tn = imagecreatetruecolor($modwidth, $modheight) ; 
                      $image = imagecreatefromjpeg($file) ; 
                       imagecopyresampled($tn, $image, 0, 0, 0, 0,$modwidth, $modheight, $width, $height) ; 

                       imagejpeg($tn, $save, 100) ; 
                       echo "Large image: 
"; 
                       echo "Thumbnail: ";
              } else {
                 echo "Unable to get image dimensions.";
              }   
}
?>

I am trying to make this to a multiple upload for those wondering....

        <button name="submitimg" type="submitimg" class="submitButton">Upload/Resize Image</button>
</form>
<?php
        if(isset($_POST['submitimg'])){
          if (isset ($_FILES['new_image'])){
              $imagename = $_FILES['new_image']['name'];
              $source = $_FILES['new_image']['tmp_name'];
              $target = "photos/".$imagename;
              move_uploaded_file($source, $target);

              $imagepath = $imagename;
              $save = "photos/" . $imagepath; //This is the new file you saving
              $file = "photos/" . $imagepath; //This is the original file

              list($width, $height) = getimagesize($file) ; 

              $modheight = 350; 

              $diff = $height / $modheight;

              $modwidth = $width / $diff; 
              $tn = imagecreatetruecolor($modwidth, $modheight) ; 
              $image = imagecreatefromjpeg($file) ; 
              imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width, $height) ; 

              imagejpeg($tn, $save, 100) ;
