control size of image fail...

joeore · April 19th, 2004, 09:05 AM

hello, i have a problem. I wrote a simple php code that checks size of an image. The problmem is: if the image size is less then 1024 kbyte the check appear ok and the returned value is correct, but if the image size is greater then 1024 kbyte, the check return 0.

Php doesen't recognize values greater the 1024 kbyte? Where is the problem?

i use php 4.32 + server apache.

this is the check code:

<?php
if (isset($_POST['button'])) {

$file = $_FILES['ico']['name'];
$size = $_FILES['ico']['size'];

echo $file . " da " . $size . " byte";

}
?>
<html>
<head>
<title>Untitled</title>
</head>
<body>

<form action='<?php $_SERVER['PHP_SELF'] ?>' method='post' enctype='multipart/form-data'>
<input type="file" name='ico' class="border4">
<input type='submit' name='button' value='inserisci' class='border2'>

</form>

</body>
</html>

Hi Joeore,

Check the following php.ini directive, this may be set to 1M instead of the default value of 2M.

; Maximum allowed size for uploaded files.
upload_max_filesize = 2M

hth,
Rich

Also, you need to ECHO the value of PHP_SELF. Your code doesn't echo it to the screen, so I wouldn't be surprised if your form action was an empty string.

this might cause a problem with some browsers. most browsers will treat an empty or missing form action as "submit to the same page".

Take care,
