PHP - Problem Checking File Size If Else Statement

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."

Hi Guys,

I'm using the following code to write emails to a .txt file:



                // Write the email to file
                $leadsFile = "leads/emails.txt";
                $fh = fopen($leadsFile, 'a') or die ("can't open leads file!");
                $writeData = "$conEM\r\n";
                fwrite($fh, $writeData);
                fclose($fh); 


which works great, but i can't figure out how to NOT write an email to the .txt file if it's already on it, i'm not using a database for a change i'm stumped lol

thanks for any help guys

Hi,

I'm trying to figure out the best way to determine if a user is currently downloading a file from my website.
The way my site works, is the user waits 30 seconds and views an ad. After the timer is up the download becomes available.
I heard that I could probably use a timestamp or something of the sort. I've read up on it but not sure how I could go about this.

I've got a page that allows users to upload a file (pdf, jpg, gif png). The user must be logged in in order to upload something. I have a query that checks if the user has already uploaded a file with the same name as the name of the file they are trying to upload.
If they have not uploaded the file yet, the file uploads and they get a "Success" message. If the file has already been uploaded by the user, they will get the message, "You have already uploaded that file".
When the query goes through, the message that shows is, "You have already uploaded that file". I ensured the file was not already in the database, and it still shows this error. I tried changing the if statement to say:

if ($duplicate==0)

instead of:

if ($duplicate!=0)

but it always shows the same error. Any ideas of what could be wrong with my code?

my sql table looks like:

Field     Type      Null     
id    int(11)    No          
userid    int(11)    No          
artist    varchar(50)    No          
title    varchar(50)    No          
file    varchar(2083)    No          
uploaded    varchar(3)    No          

Code:

<?php
session_start();

if (isset($_SESSION['username'])){

$username = $_SESSION['username'];
$submit = $_POST['submit'];

include_once('inc/connect.php');

$uploadsql = mysql_query("SELECT * FROM `users` WHERE `username`='$username'"); 
$uploadrow = mysql_fetch_assoc($uploadsql); 

$userid = $uploadrow['id']; 
$folder = "sheets/fromusers/";

if (isset($submit)){

// Name of file
$name = $_FILES["location"]["name"];
// Type of file (video/avi) or image/jpg, etc
$type = $_FILES["location"]["type"];
//size of file
$size = $_FILES["location"]["size"];
//stores file in a temporary location
$temp = $_FILES["location"]["tmp_name"];
// if there is an error
$error = $_FILES["location"]["error"];

$artist = strtolower($_POST['artist']);
$title = strtolower($_POST['title']);

// Check if fields are filled in
if($artist&&$title){

if ($error > 0)

{

// Determine the extension of the file
// If file is This File.pdf
// Then $ext is now equal to pdf

$ext = strtolower(substr($name, strrpos($name, '.') + 1)); 

if ($ext=="pdf" || $ext=="gif" || $ext=="jpeg" || $ext=="jpg" || $ext=="png")
{
if ($size <= 26214400) // If size <= 25 megabytes

I have come across couple of similar answers for my question in this form, but could not solve my exact problem. Therefore I am posting this he

I have an xml file as shown below:

<?xml version="1.0" encoding="ISO-8859-1"?>
    <document>
        <user>
            <user_id>0121</user_id>
            <name>Tim</name>
            <file>0121.file</file>
        </user>

        <user>
            <user_id>0178</user_id>
            <name>Henry</name>
            <file>0178.file</file>
        </user>

        <user>
            <user_id>0786</user_id>
            <name>Martin</name>
            <file>0786.file</file>
        </user>

        <user>
            <user_id>1239</user_id>
            <name>Jan</name>
            <file>1239.file</file>
        </user>
    </document>
I ask the user to input his user_id and post this user_id and perform a check on the entire xml file to check whether the entered user_id exists in the xml file or not. If exists then I go further if not echo a error message. Can anybody pull me out of this?

Thanks

Hi Im trying to write info to a text file and it works perfectly with the following script, but it writes duplicate info, how can I change it so that no duplicate records are being added to my file and just ignore inserting it without giving a message?  

<?php
$myfile = fopen("users.csv", "a+") or die("Unable to open file!");
$mxituid = $_SERVER["HTTP_X_MXIT_USERID_R"];
$txt = "$mxituid\n";
fwrite($myfile, $txt);
fclose($myfile);
?>

Hello,
I'm using curl to grab a new solar image once an hour or so from the Solar Dynamics Observatory (example below). I'm trying to archive new images and am struggling with that.

If I download an image, the filetime() function returns the current time since I downloaded it and wrote it to a fresh file. The result is that the file is always "new", even if the image hasn't changed on the SDO website. Do you have an idea on how to check the last modified time of a file through curl or other means so that I'm not downloading duplicate images?

Thanks a ton!



//fetch image
$ch = curl_init("http://www.somewebsite.com/theimage.jpg");
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,1);
$file = "../images/latest/theimage.jpg";
$fp = fopen($file, "w");
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);

//this part is no good...
//get last modified date
if (file_exists($file)) {
$filetime = filemtime($file);
}

I need to check a file's size with php and ssh.  Everything I've seen online for remote files uses curl and port 80.  I'll be checking a LAN computer that isn't running a webserver, but is running an SSH server.

How can I do this?

I've tried this:

Code: [Select]
<?php
$tomorrow = date ('n-j-y');
echo system(ssh root@192.168.2.169 ls -lah "/MacRadio X/WMIS Logs/WMIS $tomorrow Log" | awk {print $5});
?>

but it didn't work.  I got a T_VARIAABLE error.  This was the same command I used right from the command line, and it worked.

I'll also need to add a check to the file size, and if it's less than 175K, send me an email...but I'll work on that after I have the first part working.

Thanks!

i want to display the size of a file but i round it off to the nearest kb.

I am using...

i am geting it return something like this....
1.0313243865967mb
and i want it to be more like
1.03mb

any idears???

What's the maximum file size I can upload through a regular form ? If it's server dependant, how do I find out my max ?

I tried to handle a 550MB file (on localhost) - I only wanted to show the filename, but it hung up for about 10secs, then returned nothing.

                                         $file="../myclients/clients/".$company_name."/Download/".$file_name;
                $size = filesize($path); // not working

i try with  function  also

       function formatbytes($file, $type) 
    { 
        switch($type){ 
            case "KB": 
                $filesize = filesize($file) * .0009765625; // bytes to KB 
            break; 
            case "MB": 
                $filesize = (filesize($file) * .0009765625) * .0009765625; // bytes to MB 
            break; 
            case "GB": 
                $filesize = ((filesize($file) * .0009765625) * .0009765625) * .0009765625; // bytes to GB 
            break; 
        } 
        if($filesize <= 0){ 
            return $filesize = 'unknown file size';} 
        else{return round($filesize, 2).' '.$type;} 
    } 

echo formatbytes($file, "KB");



uploaded file size is 488 kb   

but it showing   "unknown file size"

please help me.

Hi,

Hi Chaps,

I'm using readfile to force the download of a file:

set_time_limit(0);

$file = 'monkey.gif';

if (file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename='.basename($file));
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    ob_clean();
    flush();
    readfile($file);
    exit;
}
flush();


And this works fine, however, I do have some software installation files that could be downloaded (these are in excess of 280Mb).
I have checked php.ini:
Quote

memory_limit = 128M
post_max_size = 300M


But Internet Explorer hangs and then crashes.
Is there a way to allow big files to download using this method, or is there another way of forcing the download, without php 'reading' the file first?
I'm guessing that the problem lies with the memory_limit being smaller than the file size. Is it a good idea to increase the memory_limit to eg. 280Mb?
Cheers

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

hi,

whats the best way to print labels.
I have already tried the script from fpdf.de

but i can not get my dot matrix printer (dot matrix is needed for this purpose)
the correct layout.

Its continuous paper, with size 110 height x 62mm width (for each label).
I am not able to select a self-adjustable paper-size. so i hope to solve this
with PHP / PDF if possible.

anyone have experience with this?
cheerz!!
