Opening Uploaded File

[vital101]

Hey everyone,

 

I'm having some difficulty opening an image file that has been uploaded from a form.  I upload the file (that works fine), but then when I go to open it, I have no luck.  I keep thinking that maybe my path to the image is wrong, but i don't think it is.  Any help would be awesome.  Thanks!

 

<?php
//Create SQL Connect, test for connectivity.
$con = mysql_connect("", "myuser", "mypass");
if (!$con) {
	die("An error has occurred connecting to the database.");
}
//Select the database to use.
mysql_select_db("mydb", $con);

//Construct the query
$query = "SELECT * FROM images";
$result = mysql_query($query);
$image_number = mysql_num_rows($result) + 1;
$id_number = mysql_num_rows($result) + 1;
$image_number = $image_number . ".jpg";

//Target is the path and filename where the image will be stored.
$target = "uploads/$image_number";
//$target = $target . basename( $_FILES['uploaded']['name']) ;
$ok=1;

//This is our limit file type condition
if ($uploaded_type =="text/php")
{
echo "No PHP files<br>";
$ok=0;
}

//Here we check that $ok was not set to 0 by an error
if ($ok==0)
{
echo "Sorry your file was not uploaded";
}

//If everything is ok we try to upload it
else
{
	move_uploaded_file($_FILES['uploaded']['tmp_name'], $target);
}

//Open the image stream.
$image = open_image('/www/facebook/morningAfter/images/$image_number');

//Check to make sure image stream opened.
       /*****  THIS IS WHERE IT BREAK!  *****/
if ($image === false) {
		die ('Unable to open image');
}

//Dynamically resize images down to a width of 125px or less
if($width > 125) {	
	$width = imagesx($image);
	$height = imagesy($image);
	$ratio = 125 / $width;
	$new_width = 125;
	$new_height = (int)($height * $ratio);

	// Resample
	$image_resized = imagecreatetruecolor($new_width, $new_height);
	imagecopyresampled($image_resized, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

	imagejpeg($image_resized, "/www/facebook/morningAfter/images/$image_number", 83);
	imagedestroy($image);
	imagedestroy($image_resized);
	echo "done!";
} else {
	imagejpeg($image, "/www/facebook/morningAfter/images/$image_number", 83);
	imagedestroy($image);
}

//Now, insert this new beauty into the database of images.  But first, get the timestamp.
$currentTime = time();
$formattedTime = gmdate("Y-m-d H:i:s", $currentTime);

$query = "INSERT INTO images (id, name, date_added, popularity) VALUES ($id_number, '$image_number', '$formattedTime', 0)";
mysql_query($query);

//Great! Forward the user on to selecting a friend.
header('Location: http://apps.facebook.com/morningafter/upload_complete_catcher.php?itemID=$id_number');

Oh, and my host is BlueHost, so I don't know if this problem is specific to them or not.

Your $target variable seems to be using a relative path rather then an absolute path like what you are using in your call to the 'open_image()' function.

 

Have you checked if the file at '/www/facebook/morningAfter/images/$image_number' even exists?

[vital101]

Yes, the file does exist.  That's why I can't figure out what's wrong.  When opening the file, I've tried using absolute paths, relative paths, and everything in between, with no luck.  My directory structure looks something like this:

 

-/home/theloobc/

  -/www

    -/facebook

      -/morningAfter

        -/images

        -/uploads

[dptr1988]

Well I you are sure that the file exists and PHP has read access to it, it must be the image opening functions.

 

Have you been ever able to use PHP's GD image functions on this server?

 

Have you checked the format of the image that you are trying to open?

 

 

 

[vital101]

Yes, GD is installed on the server.  Yes, the image format is correct.

[dptr1988]

Well, then I'm out of suggestions.

 

Here is what I would do if I were in a situation like that.

1. I would upload an image of a known quality/format to a location on the webserver.

2. Create a brand new script that trys to open the image

<?php
$path = '/path/to/your/image.jpg';
$result = imagecreatefromjpeg($path);
var_dump($result);
?>

3. Look at the output from this script and see if it works

 

 

Also I noticed that on your original script you are using the '@' char for error suppression. You should remove that while you are debugging.
