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.

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...

there is no images folder next to your .php file

or you did not set the 'write' permit.

          if (isset ($_FILES['new_image'])){
          if(!file_exists("images"))
          {
		  mkdir("images" , "0744") or die("Could not create images folder");
		  die("folder created!");
          }

ok i went and copied the file on my server in a subdomain. the file seems to be uploading to the website but then for some reason it doesnt get there in the end.

i made an images folder in the root and gave it full write permisions (777)

i then run the script where it was uploading the file ( could see the 5 meg traffic going through the router ) but then once again it gave me the same problem...

[its ok for me... did you repaired something ?

[aarchaic]

you know what i think its been limited with my config file i just used a 300kb file and it worked.

but thanks for your help! its uploading!

now back to the part that i need to make 3 images preferably with random names...

1. large image of 500 pixels on the long side
2. medium image of 195 pixels on the long side
3. the thumb of 80 pixels on the long side.

4 work in an image size checker...

thanks for your help djjjozsi

OK after a weekend of struggling i manage to work it out here the code is now.
