Problem with imagecreatefromjpeg();

[mjurmann]

Hello,

 

I'm trying to run this script on my site (it worked fine with GoDaddy and Dreamhost shared servers, but not my dedicated server I'm using now):

 

<?php if ($_FILES['uploaded2']['tmp_name'] == NULL) {

}

else {


// This is the temporary file created by PHP
$uploadedfile = $_FILES['uploaded2']['tmp_name'];

echo $uploadedfile;
echo "<br/>";
echo "<br/>";
// Create an Image from it so we can do the resize
$src = imagecreatefromjpeg($uploadedfile);

echo $src;

// 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=150;
$newheight=($height/$width)*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.
$filename = "games_images/thumbs/".$pictureNum."_".$_FILES['uploaded2']['name'];
imagejpeg($tmp,$filename,100);

echo $filename;

imagedestroy($src);
imagedestroy($tmp);

// NOTE: PHP will clean up the temp file it created when the request
// has completed.
}
?>

 

For some reason, when I run:

 

$src = imagecreatefromjpeg($uploadedfile);

 

echo $src;

 

Nothing is echoed back from $src. For some reason, imagecreatefromjpeg() is not returning any information to be assigned to the $src variable. However:

 

echo $uploadedfile;

 

Returns the temporary file name from the upload field from the previous page.

 

I recompiled Apache in WHM with GD selected, and GD shows up as enabled in my phpinfo() (viewable at http://www.gameargus.com/test.php), but this function still doesn't seem to be working.

 

As I said, it worked fine on Godaddy and Dreamhost, so there has to be something setup incorrectly here on the dedicated server.

Try running:

 

<?php

$src = imagecreatefromjpeg($uploadedfile);
var_dump($src);

?>

 

The information it will give might be helpful. Also turn error reporting to all by writing in the beginning:

error_reporting(E_ALL);

Maybe you will get a warning that will explain everything.

 

 

Orio.

Here is the information I get when I run those commands:

 

var_dump($src) returns: bool(false)

 

error_reporting(E_ALL) returns:

Well, it's pretty straight forward- It tells you the file doesn't exist. Try saving the file in a temporary folder and then open it from there.

 

Orio.

[mjurmann]

How do I go about coding that? I have no idea what I'm doing here...I'm taking a file I've uploaded and running a script to convert it to a thumbnail; however, it is basically telling me that the /tmp folder foesn't exist, even though it does.

[Orio]

Create a folder called tmp_imgs in the folder with the script and do it this way: (The part between the *** is my addition)

 

<?php if ($_FILES['uploaded2']['tmp_name'] == NULL) {

}

else {


// This is the temporary file created by PHP
$uploadedfile = $_FILES['uploaded2']['tmp_name'];

echo $uploadedfile;
echo "<br/>";
echo "<br/>";

//********************************************
//Move file to temp folder, using some random filename
$tmp_name = "tmp_imgs/".time().rand(0,1000).".jpg";
move_uploaded_file($_FILES['uploaded2']['tmp_name'], $tmp_name);
$uploadedfile = $tmp_name;
//*******************************************

// Create an Image from it so we can do the resize
$src = imagecreatefromjpeg($uploadedfile);
unlink($tmp_name); //*******I added this too***** Delete the tmp file

echo $src;

// 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=150;
$newheight=($height/$width)*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.
$filename = "games_images/thumbs/".$pictureNum."_".$_FILES['uploaded2']['name'];
imagejpeg($tmp,$filename,100);

echo $filename;

imagedestroy($src);
imagedestroy($tmp);

// NOTE: PHP will clean up the temp file it created when the request
// has completed.
}
?>

 

 

Orio.

Now I'm getting this:

 

 

tmp_imgs/1190757401460.jpg

Warning: imagecreatefromjpeg(tmp_imgs/1190757401460.jpg) [function.imagecreatefromjpeg]: failed to open stream: No such file or directory in /home/gameargu/public_html/cms/htms/admin-games-image-uploaded.php on line 322

bool(false)

Warning: getimagesize(tmp_imgs/1190757401460.jpg) [function.getimagesize]: failed to open stream: No such file or directory in /home/gameargu/public_html/cms/htms/admin-games-image-uploaded.php on line 326

 

I used the code you suggested and CHMOD 777 the tmg_imgs directory...

 

<?php if ($_FILES['uploaded2']['tmp_name'] == NULL) {

}

else {
error_reporting(E_ALL);

// This is the temporary file created by PHP
$uploadedfile = $_FILES['uploaded2']['tmp_name'];

echo "<br/>";
echo "<br/>";


//********************************************
//Move file to temp folder, using some random filename
$tmp_name = "tmp_imgs/".time().rand(0,1000).".jpg";
move_uploaded_file($_FILES['uploaded2']['tmp_name'], $tmp_name);
$uploadedfile = $tmp_name;
//*******************************************

echo $uploadedfile;

[Orio]

Are you sure you named the folder tmp_imgs? Try commenting the line with the unlink() and then upload a file and see if you can find it in the folder.

 

Orio.

[mjurmann]

How do you use unlink() ?

[Orio]

There's another line I marked with ****** with unlink(), it deletes the temp file.

 

Orio.

[mjurmann]

I can confirm that the directory exists and also that it is writable.

 

I used:

 

  <?php
$target = "tmp_imgs/";
$target = $target .$pictureNum."_banner_". basename( $_FILES['uploaded2']['name']) ;
$ok=1;




if ($uploaded_size > 350000)
{
echo "Your file is too large.<br>";
$ok=0;
}




if ($ok==0)
{
Echo "Sorry your file was not uploaded";
} 


else
{ 


if(move_uploaded_file($_FILES['uploaded2']['tmp_name'], $target))
{
chmod($target, 0777);

}
else {
echo "Sorry, there was a problem uploading your file.";
}


}



?>

 

and the file was correctly placed in this directory.

 

The only problem seems to be using the imagecreatefromjpeg function. I can save the files directly to the sever, but when I need to resize them using imagecreatefromjpeg its giving me these errors

[Orio]

Beats me. Seems to be a problem with GD or something.

 

Orio.

[mjurmann]

Well thanks anyways for your help Orio

[Orio]

No probs, good luck.

 

Orio.

[mjurmann]

Orio, if you're out there...

 

In my phpinfo it says:

 

--with-gd' '--with-jpeg-dir=/usr/local'

 

Do I need to specify somewhere that the directory to write the temporary file is /usr/local?

[mjurmann]

I beg someone to please help me. 15 hours of sitting at the computer and I still can't get this!
