Strange thing with max image upload file size.

[scdogas321]

Hello every one, so i got this little problem. I have this code:

$limit_size=50000;

if($name >= $limit_size){
echo "Your file size is over limit";
}

So i guessing that 50 000 ~ 50Kb

And the weird part:
So when I'm trying to upload file with 500Kb size it's says that 'Your file size is over limit'
But when I'm trying to upload file with 2Mb size then everything is okay and file uploading fine...
Can anyone help me? Thanks 🙂

[scdogas321]

By the way.

500Kb gif file = Error (File size is too big.)
2mb png = Fine
130Kb png = Fine
199Kb Jpg = Error (File size is too big.)
40Kb Jpg = Fine

Can someone explain me and tell me how to fix it?

50,000 ... what? Red balloons? Sea turtles? Bytes? If it's the last one you meant, then you're close... 50,000 B is approximately 48.83 KB.

Can you show us more of the relevant code? For example, we have no idea how you've defined $name (or why that variable name apparently has nothing to do with what it represents).

[scdogas321]

if ($_POST['upload']) {
		require("./connect.php");

$name = $_FILES['image']['name'];
$tmp_name = $_FILE['image']['tmp_name'];

	if ($name) {

			$extensions = array('.png', '.gif', '.jpg', '.jpeg');  
			$extension = strrchr($_FILES['image']['name'], '.');  

			if(!in_array($extension, $extensions)){ 

				echo "<font color='red'>Blogas formatas.</font>";

			}

		else {

		$limit_size=50000;

			if($name >= $limit_size){
			echo "<font color='red'>J&#363;s&#371; failo dydis per didelis.</font>";
			}
			else {


			$location = "images/avatars/$name";
			$path = "images/avatars/".$HTTP_POST_FILES['image']['name'];
			rename($HTTP_POST_FILES['image']['tmp_name'], $path);


			$query = mysql_query("UPDATE user SET imageloc='$location' WHERE username='$username'");
			echo "<script type='text/javascript'>    
										window.location.reload('../index.php');    
										window.close();
										</script>   ";


			}
		}
	}
	else
		echo "<font color='red'>J&#363;s turite pasirinkti nuotrauk&#261;.</font>";


mysql_close();
}

echo "<form action='redaguoti_profili.php' method='post' enctype='multipart/form-data'>

			<center><input type='file' name='image'> <input type='submit' name='upload' value='&#302;kelti'></center>
			</form> <br />";			

And I want to make max size 800kb for jpg, jpeg, gif, png.

You'd have more success trying to see if the file's size is over the limit instead of trying to see if it's name is over the limit.

$_FILES['image']['size']

[scdogas321]

I added

$size = $_FILE['image']['size'];

And changed $name to $size in if, and i can upload all files even 2mb, 500kb... all. :/

I'd be all for testing [man]ini_set/man for this issue....

[scdogas321]

Okay, i added in php.ini: max_upload_filesize = 800K

And added in to my php: ini_set("upload_max_filesize")

And when im trying to upload 900Kb it's says:

Warning: ini_set() expects exactly 2 parameters, 1 given in /home/gameriai/domains/gameriai.us.lt/public_html/redaguoti_profili.php on line 562
Your file is too big.

And it's says like that for all my images... :/?

[dalecosp]

You need to tell ini_set not only which parameter you want to set, but also what the setting should be:

//Looky!  TWO parameters!
ini_set("upload_max_filesize",800000); // I think that's the right number.

But, since you've already modified your php.ini, you don't need to call ini_set() any longer --- just take it out and the error message will disappear.

[scdogas321]

Basically i downloaded default php.ini and insert in to my public_html. I tried your way:

ini_set("upload_max_filesize",800000); // I think that's the right number. 

Now there are no errors from bad coding but, there is this one error: Your Image is too big.
And it's for any image that I uploading.
When I'm trying to use ini_get(); Its doing nothing. With ini_get(); i can upload any size image.
Hmmm :/

[dalecosp]

Well, please read the manual. [man]ini_get/man returns the value for an ini setting, and [man]ini_set/man sets that value if it is settable by the user or script that makes the call.

"Your Image is too big" isn't an error. That's what you wanted ... a limit on the size of images to be uploaded, right?

Only problem is that wouldn't do anything; PHP has already made the decision whether or not to accept the upload before it even parses your code.

@: Try adding an echo statement that outputs the value of $size and let us know what it reports for the files that you claim should be rejected. Also show us a new copy of what your code looks like now.

[scdogas321]

Well my code is:

	if ($_POST['upload']) {
		require("./connect.php");

$name = $_FILES['image']['name'];
$tmp_name = $_FILE['image']['tmp_name'];
$size = $_FILE['image']['size'];
[COLOR="#FF0000"]echo "$size";[/COLOR]

	if ($name) {

			$extensions = array('.png', '.gif', '.jpg', '.jpeg');  
			$extension = strrchr($_FILES['image']['name'], '.');  

			if(!in_array($extension, $extensions)){ 

				echo "<center><font color='red'>Bad format.</font></center>";

			}

		else {

		$max_upload = ini_get("upload_max_filesize");



			if($FILES['size'] >= $max_upload){
			echo "<center><font color='red'>You image is too big.</font></center>";
			}
			else {

And that int_get doing nothing. :/ Sorry guys, it's night time in my country now and i think that I'm going to sleep, Good night 😃.
I'll replay you as soon as i can 🙂

Well that should be expected; if a file was larger than the upload_max_filesize directive, PHP would have already deleted/rejected the upload before it even began executing your script.
