PHP and image uploading

aarchaic

Hello Guys

i'm still on the images and uploading. and since not having worked on this before i'm really struggling.

i found this script:

PHP: Upload and resize image script ( http://www.theopensurgery.com/29/php-upload-and-resize-image-script/ )

<form action="<?php echo $_server['php-self'];  ?>" method="post" enctype="multipart/form-data" id="something" class="uniForm">
        <input name="new_image" id="new_image" size="30" type="file" class="fileUpload" />
        <button name="submit" type="submit" class="submitButton">Upload/Resize Image</button>
</form>
<?php
        if(isset($_POST['submit'])){
          if (isset ($_FILES['new_image'])){
              $imagename = $_FILES['new_image']['name'];
              $source = $_FILES['new_image']['tmp_name'];
              $target = "images/".$imagename;
              move_uploaded_file($source, $target);

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

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

          $modwidth = 150; 

          $diff = $width / $modwidth;

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

          imagejpeg($tn, $save, 100) ; 

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

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

          $modwidth = 80; 

          $diff = $width / $modwidth;

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

          imagejpeg($tn, $save, 100) ; 
        echo "Large image: <img src='images/".$imagepath."'><br>"; 
        echo "Thumbnail: <img src='images/sml_".$imagepath."'>"; 

      }
    }
?>

I've copied it and made an images directory in my root of my server and tried running it. and i got this whole list of errors.

Warning: getimagesize(images/_DSF8681johan.jpg) [function.getimagesize]: failed to open stream: No such file or directory in D:\wamp\www\alphaVer3\upload-size.php on line 17

Large image: ( Broken Image )
Thumbnail: ( Broken image )

I also want to make it so it will resize the photo in 3 versions. a big photo with a 500 pixel long side, a medium photo with a 195 pixel longside and a thumbnail with a 80 pixel long side.
and then read the image filename with the path into a database.

can someone please shed some light on this for me please!

Thanks

is it a defined variable? $server['php-self']
you've better use the $SERVER['PHP_SELF']

              $imagename = basename($_FILES['new_image']['name']);
              $source = $_FILES['new_image']['tmp_name'];
              $target = "images/".$imagename;
              move_uploaded_file($source, $target);

Thanks i did that here is the code now

<form action="<?php echo $_SERVER['PHP_SELF'];  ?>" method="post" enctype="multipart/form-data" id="something" class="uniForm">
        <input name="new_image" id="new_image" size="30" type="file" class="fileUpload" />
        <button name="submit" type="submit" class="submitButton">Upload/Resize Image</button>
</form>
<?php
        if(isset($_POST['submit'])){
          if (isset ($_FILES['new_image'])){
              $imagename = basename($_FILES['new_image']['name']);
              $source = $_FILES['new_image']['tmp_name'];
              $target = "images/".$imagename;
              move_uploaded_file($source, $target);

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

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

          $modwidth = 150; 

          $diff = $width / $modwidth;

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

          imagejpeg($tn, $save, 100) ; 

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

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

          $modwidth = 80; 

          $diff = $width / $modwidth;

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

          imagejpeg($tn, $save, 100) ; 
        echo "Large image: <img src='images/".$imagepath."'><br>"; 
        echo "Thumbnail: <img src='images/sml_".$imagepath."'>"; 

      }
    }
?>

But it still giving me the same errors...
