//LOAD IMAGE TABLE

        $filename = $_FILES["file"]["name"];

        $image_info = getimagesize($filename);
        $image_width = $image_info[0];
        $image_height = $image_info[1];

        echo "filename1 : ".$_FILES["file"]["name"];
        echo "filename : ".$filename;
        echo "image info : ".$image_info[0];
        echo "image info : ".$image_info[1];
        echo "image width : ".$image_width;
        echo "image height : ".$image_height;

$_FILES["file"]["name"] as a file does not exist on the server, try the temp file instead:

$filename = $_FILES["file"]["tmp_name"];

You may want to move the file to a permanant location first using move_uploaded_file. The temp directory may have unusual permissions preventing you from reading the file, and these temp files are deleted very quickly as well. Without the rest of the context for your script it is hard to say if the file will still exist when you are running this.

This works for me:

if($_FILES)
{
    $tmp = $_FILES['file']['tmp_name'];
    $data = getimagesize($tmp); 
    print_r($data);
}
?>

<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
</head>

<body>
<form method="post" enctype="multipart/form-data">
    <input type="file" name="file" />
    <input type="submit" value="Upload" />
</form>
</body>
</html>

This is the output:

Array ( [0] => 480 [1] => 640 [2] => 2 [3] => width="480" height="640" [bits] => 8 [channels] => 3 [mime] => image/jpeg )

As suggested by Isaac_4 try moving your upload file to a new directory.

$upload_path = '/uploads/';
$file = $_FILES['file']['name'];

if(move_uploaded_file($_FILES['file']['tmp_name'],$upload_path.$file)){
    echo $file . ' has been uploaded';
}else{
    echo $file . ' has not been uploaded';
}

The same problem:

update_image2.php

//LOAD IMAGE TABLE

            $filename = $_FILES["file"]["tmp_name"];

            $image_info = getimagesize($filename);
            $image_width = $image_info[0];
            $image_height = $image_info[1];

            echo "filename1 : ".$_FILES["file"]["name"].'<br>';

            $image = $_FILES["file"]["tmp_name"];

line 267: $image_info = getimagesize($filename);

The thing is I have to figure out the file size before I copy it to a new location.

I have to limit the file size so that I wouldn't be too small or too large.

So I try this:

Warning: getimagesize(C:\xampp\tmp\php1263.tmp): failed to open stream: No such file or directory in C:\xampp\htdocs\SquprimeRevise\administrator\admin\update_image2.php on line 289

line 289:
$data = getimagesize($tmp);

Xampp version 3.2.1.

diafol · Answer 5 · 2014-10-15T10:56:44+00:00

Xampp seems to be version 1.8.3 at the moment - how can it be 3.2.1?

have you tried?

//Change the file size to whatever you need to be.
if( $_FILES['file'][size] > 98174 ){
    echo $_FILES['file'][error];
    exit;
}

davy_yg 2 Posting Whiz · Answer 8 · 2014-10-16T15:57:24+00:00

Well, that's the limit the file size (in MB) while I am trying to limit the file width and height (in pixels)

Here is a more complete picture of the codes:
