PHP - Image Upload File Size Limit

Hi Guys

Probably a simple answer here that i'm missing.

I've got a simple upload script for an image uploader that does various checks for security sake.

One of the checks is on file size to make sure it doesn't exceed the upload limit set in php.ini . The limit is set at 2mb, so the script checks that the file doesn't exceed this limit.

The problem occurs when I try to upload a file that far exceeds the limit (the one below is 3.5mb). When i do this the upload gets passed my script because the $_FILES['picture1']['size'] gets set to no value. A print_r of the files array shows:

Code: [Select]
[picture1] => Array
        (
            [name] => DSC01468.JPG
            [type] =>
            [tmp_name] =>
            [error] => 1
            [size] => 0
        )

So what i wanted to know was whether this was normal?

And should i simply do a check to see if the size value is empty?

Any advice would be good!

Thanks Drongo

Hello! I have this validation script that seems to work great until I add the size validation. I'm ready to pull my hair out! Can someone tell me what I'm doing wrong?

Code: [Select]
if (isset($_POST['Submit'])) {
$user_id = $userdata[user_id];
    $number_of_file_fields = 0;
    $number_of_uploaded_files = 0;
    $number_of_moved_files = 0;
    $uploaded_files = array();
$max_filesize = 5242880; // Maximum filesize in BYTES (currently 5MB).
    $upload_directory = dirname(__file__) . '/'.$user_id.'/'; //set upload directory
if (!is_dir($upload_directory)) {
    mkdir($upload_directory, 0777, true);
}

    for ($i = 0; $i < count($_FILES['images']['name']); $i++) {
        $number_of_file_fields++;
        if ($_FILES['images']['name'][$i] != '') { //check if file field empty or not
            $number_of_uploaded_files++;
if($_FILES['images']['size'] > $max_filesize){
echo "<b class='red'>Max file size is 5MB.</b><br/>";
$sz = true;
}
$ext = validate_extension($_FILES['images']['name'][$i]);
if (($ext == true) && ($sz == true)){
$uploaded_files[] = $_FILES['images']['name'][$i];
if (move_uploaded_file($_FILES['images']['tmp_name'][$i], $upload_directory . $_FILES['images']['name'][$i])) {
$number_of_moved_files++;
            }
}else { echo "<b class='red'>File extention error. Only .doc, .pdf, .jpg and .gif files are allowed. </b><br/>";
}

        }

    }
if ($number_of_uploaded_files >= 1){
echo "Number of files submitted:<b class='red>".$number_of_uploaded_files."</b><br/>";
echo "Number of successfully uploaded files:<b class='red>".$number_of_moved_files."</b><br/><br/>";
echo "Uploaded File Name(s):<br/>" . implode('<br/>', $uploaded_files);
}


}
As of now it results in every uploaded file returning the error "Max file size is 5MB."

Unless buffer overflows or breaking out of code to perform a new command are problems that have been solved....

I am trying to figure out the proper PHP method for setting a boundary on a variable within a script. I have this variable $name which is fed a value from $_POST['name'] from a form field. Now this form field is limited in the HTML to accept only 20 characters, but someone could easily edit the form or outgoing post data. So I want to know how to limit the variable size in the script. In other languages it could be something like this: var name(20). So how do I do that in PHP?

how to put code for check file size before upload  in the if issertfile .the file is in format pdf or docs 

 $targetDirg= "folder/pda-semakan/gambar/";
 if(isset($_FILES['gambar'])){
     $fileNameg = $_FILES['gambar']['name'];
 $targetFilePathg = $targetDirg . $fileNameg;
 //$main_tmp1 = $_FILES['surat']['tmp_name'];
 $moveg =move_uploaded_file($_FILES["gambar"]["tmp_name"], $targetFilePathg);
 }  
         
 

 

I've got a basic form for users on the site to fill out a form and upload a single image which is resized and saved to a directory on the server. I've tried the form numerous times and with images usually under 1MB the form successfully submits, data is queried and the image uploaded is resized and saved. However, recently I tried uploading larger sized images (1.2mb, 2.4mb, 3mb) and the script would seem to break. It wouldn't query any information, save any images, etc.

If you check my code attached, I have errors ready to output at all levels and not even any errors show up. When I hit submit after attempting to upload a larger file usually over 1MB, the page refreshes back to PHP_SELF as if it submitted but returns absolutely no message, alert or error and the form which was on the page is now gone.

I checked my PHP.ini file and my max file size upload is set at 32mb. Is there anything else with file size restrictions that I could be missing that is allowing this script to crash without even sending me any errors?

Hi:

I have a site hosted (shared) on 1and1.com hosting, and they seem to have a file upload limit of 2MB.

Is there a way to overwrite this? I have been trying a .htaccess and php.ini file, but can't get it to work.

The folder with the upload form is called "admin," in the ROOT of the site.

Been trying (in both the ROOT and the "admin" folder):
php.ini
Code: [Select]
; Maximum size of POST data that PHP will accept.
post_max_size = 8M

; Maximum allowed size for uploaded files.
upload_max_filesize = 8M

ini_set('memory_limit','128M');

.htaccess (in both the ROOT and the "admin" folder):
Code: [Select]
php_value memory_limit 24M

That is all the code in each file - am I missing some code?

Can this be done?

Thank you.

Is there a way I can get the .jpg file in kilobytes from a remote url and check it to make sure it does not exceed 40 kilobytes before it saves the remote url into my database?

Hi,

I'm developing a code that uploads images. I need to verify if the image have the minimum size of 100*100 pixels before the upload. How can I do this?

Best Regards,

Sorry for my bad english.

Hey there so I'm using the below code to upload images/files to my server via ftp. The issue I've found is that anything bigger than 200KB either stalls out and partially uploads or doesn't upload at all.

I've set my php.ini file to have upload_max_filesize = 1000M and post_max_size = 1000M. And still anything bigger than 200KB won't upload right. Any help would be appreciated. I'm using php version 5.2.14 fyi. Thanks so much.


---CODE---
<?if(!isset($_POST["submit"])){?>

<!-- THE FORM ACTION IS ONTO ITSELF -->
<form action="index.php" method="POST" enctype="multipart/form-data">
<input name="userfile" type="file" size="40">
<input type="submit" name="submit" value="Upload image" />

</form>

<?
}
else
{

set_time_limit(30000);//i noticed that this had to be pretty big otherwise your upload was likely to stall out.

$paths='/yourfilepath/yourfilepath/';

$filep=$_FILES['userfile']['tmp_name'];

$ftp_server='ftp.yourdomain.com';

$ftp_user_name='your_user_name';

$ftp_user_pass='your_password';

$name=$_FILES['userfile']['name'];



$conn_id = ftp_connect($ftp_server);

$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

if ((!$conn_id) || (!$login_result)) {
echo "FTP connection has encountered an error!";
echo "Attempted to connect to $ftp_server for user $ftp_user_name....";
exit;
} else {
echo "";
}

$upload = ftp_put($conn_id, $paths.'/'.$name, $filep, FTP_BINARY);

if (!$upload) {
echo "FTP upload has encountered an error!";
} else {
echo "Uploaded file with name $name Succsessfully ";
}

ftp_close($conn_id);   

}
?>

(1) What does this actually do? (compress it?)

$image = imagecreatefromjpeg("image.jpg");
header('Content-Type: image/jpeg');
imagejpeg($image);

By using this rather than displaying by using www.site.com/image.jpg it reduces file size of an image from 2.5mb to 0.5mb !!

(2) ImageMagick can't get these results. Am I doing something wrong? If I change the pixel size of an image in ImageMagick then I can reduce its file size, but (1) above reduces file size regardless of changing pixel size.

hello
anyone can help me to reduce image file size(reduce quality of images) using php ?

I have a flash application that calls php script to do the image file upload and save the image in jpg format in thumbnail size. I swear it worked at one time, and then as I tried to figure out how to covert other image formats that are not currently built-in in php library (createimagefrom... functions), I played around with it a little bit, then it doesn't upload file any more!!! What I got, is that NONE of the image files is saved in my designated image folders, subsequently the flash application comes up with a broken image link.  PLEASE HELP! MANY THANKS!

Here's the relevant flash code:
Code: [Select]
private function uploadFiles():void
{
var curTime:Date = new Date();
timeStamp = curTime.valueOf().toString();
var variables:URLVariables = new URLVariables("timeStamp=" + timeStamp);

  var request:URLRequest = new URLRequest(ModelLocator.getInstance().serverPath+"uploadArtImages.php");
request.method = URLRequestMethod.POST;
request.data = variables;
file.upload(request);
  Application.application.showLoading();
}

Hi I am new to PHP...
I wanted to design a banner.. the require data should be entered by user like Name of a banner, Details as well as Image to display on it.

I think for this I may need to use file upload option.. I tried this but $Files not working for me... some times its shows diff errors on diff browsers, I am new to PHP I dont know what is the prob.

I dont have any code on this... if anyone have any tutorial on this, that will be the gr8 help as I am trying to solve this from last 1 and 1/2 week..

I used http://www.tizag.com/phpT/fileupload.php
its showing error msg There was an error uploading the file, please try again!

Thanks in adavnce

files that upload during insert/submit form was gone , only files upload during the update remain , is the way query for update multiple files is wrong ?

$targetDir1= "folder/pda-semakan/ic/";
if(isset($_FILES['ic'])){
     $fileName1 = $_FILES['ic']['name'];
 $targetFilePath1 = $targetDir1 . $fileName1;
 //$main_tmp2 = $_FILES['ic']['tmp_name'];
$move2 =move_uploaded_file($_FILES["ic"]["tmp_name"], $targetFilePath1);
}

$targetDir2= "folder/pda-semakan/sijil_lahir/";
if(isset($_FILES['sijilkelahiran'])){
     $fileName2 = $_FILES['sijilkelahiran']['name'];
 $targetFilePath2 = $targetDir2 . $fileName2;
$move3 =move_uploaded_file($_FILES["sijilkelahiran"]["tmp_name"], $targetFilePath2);
}

$targetDir3= "folder/pda-semakan/sijil_spm/";
if(isset($_FILES['sijilspm'])){
     $fileName3 = $_FILES['sijilspm']['name'];
 $targetFilePath3 = $targetDir3 . $fileName3;
$move4 =move_uploaded_file($_FILES["sijilspm"]["tmp_name"], $targetFilePath3);
}
