PHP - Help In File Uploads.

Hi, I want to let users upload multiple images to my online picture book, so after they press submit, HOW do I count the total $_FILES[someName]['name'] uploaded. I want to allow users to type in html form the total uploads they want and this will then display that many desired upload forms.

I'm going to try count($_FILES[][]) and go from there first...

Any help much appreciated!

Hello.

My script is set to upload files upto 5GB large.

For that script I've currently set memory_limit to 5GB. Is it alright?

I mean what is the ideal value (for large upload scripts)

If you feel, 5GB is large. I can make script to upload 2GB files and set memory_limit accordingly.

Also, max_execution_time has been set by me to 86400 currently. Assuming, on a 500Kbps broadband, it would require upto 24 hours to upload a 3-5GB file.

Please suggest.

Thank you.

I've got a typical form with an input type="file" for users to upload photos to my site (2mb max to be exact). If you view my code below, you'll notice that I set a variable as the uploaded file's size, and a variable for the max file size I want in bytes. When making sure that the uploaded file's size is LESS than the limit size I set, it should push an error.

However, I've noticed that my variable $uploadSize that is supposed to grab the upload file size is only returning "0" (zero). I've tried var_dump($_FILES) to see what was going on and it shows the array with the proper name of the uploaded file, etc. but the file size returns 0.

So any file size I upload will bypass my test to see if the file size is less than the limit size. I've tested uploading images 2mb or less and the photos have successfully been queried, moved and resized. However, if I try and upload images LARGER than 2mb, the form still queries all the inputted data into the database but the image isn't successfully moved.

I've used this same form and approach on a previous project and I didn't have any trouble. Can I get your guys' eyes on this and see if I'm missing anything small?

Code: [Select]
<?php

if(isset($_POST['submit'])){

Awhile ago I wrote a simple form to except image specific uploads from users and chmoded the directory to 777... worked great...

Till there was a hack and then I found that chmod 777 is bad

So changed the folder to 775, but now the upload script won't work.

Can somebody point me to a post or article on how to give a file ownership or group permissions so it can safely run its uploads to the folder?

I have tried google but keep getting Linux and Window OS results.. its a tough question to google.

Any help is very much appreciated.

Hi

Have got my form working for all standard bits.  Just need to add the functionality for people to upload photos.  I copied and modified the form from a site and there is a section that I think is redundant it still works when I comment it out can you clarify for me:

Code: [Select]

    // validation expected data exists
 /*   if(!isset($_POST['first_name']) ||
        !isset($_POST['last_name']) ||
        !isset($_POST['email']) ||
        !isset($_POST['telephone']) ||
        !isset($_POST['comments'])) {
        died('We are sorry, but there appears to be a problem with the form you submitted.');       
    }
     */

Below is the full code for the form:

From what I've been reading you need to tell the php to put it to a temporary file from the submit.. then move it to the file name and then somehow include that file name in the php email back.  So maybe a url and its private or htaccess? or does it get included as attachment in the mail?

Im not sure if i should be using 'id' or 'name' in the html form etc and how to tie it together.

Any help or guides much appreciated.

Thanks

This upload code is used for uploading a video file from html page, after recording via html5 screen <video></video>, however, ther file doesn't arrive in the uploads/ folder:

 

<?php
foreach (array('video', 'audio') as $type) {
    if (isset($_FILES["${type}-blob"])) {

        $fileName = $_POST["${type}-filename"];
        $uploadDirectory = 'uploads/' .rand(5,500).$fileName;

        if (!move_uploaded_file($_FILES["${type}-blob"]["tmp_name"], $uploadDirectory)) {
            echo (" problem moving uploaded file");
        }
    }
}

when uploaded from iPhone. So, I don't know how to see errors on iPhone. Folder permission is 755. php.ini max file size is 2024M,

any ideas/solutions are appreciated.

 

 

I have a file upload script that will eventually process a ton of files.  I would like to upload them into sub-directories according to what year, month, and day they are uploaded.     A typical tree should look like this:   attachments/ --/2014 -----/January --------/01 --------/02 --------/03 , etc. -----/February --------/01 --------/04 --------/09 --------/18 --------/20, etc -----/March, etc --/2015, etc.   So a file called image.jpg uploaded on 10/31/2014 would have a URL of attachments/2014/October/31/image.jpg.  I understand that every time a file is uploaded, the script would have to detect through FTP whether or not folders for the year, month, and day exist, and if they don't create them.  My problem is that I have no idea what the logic of this script would be.  What order should I do things in?  Is there a way to use maybe foreach to detect/create the folders?  Any input would be appreciated.    

Stumped!  I have a client who has a form where they upload files to their server: title, two password fields, and the file They have been unable to upload anything over 10m   Small (under 10mb) files work. Larger doesn’t I’ve tracked it down, I think, that the processing page appears to be dropping the form values when the file takes a bit to upload.   I echo’ed the values that are grabbed from the form, and they return empty strings if it takes a while for the file to upload (a large file) - they pass fine if the file is smaller.   I think I've got the php info set correctly, but cannot for the life of me figure out how to adjust the timing out issue, or even where to troubleshoot.   Here's my phpinfo:   Max Requests Per Child: 750 - Keep Alive: off - Max Per Connection: 100 Timeouts Connection: 120 - Keep-Alive: 5     Directive Local Value Master Value allow_call_time_pass_reference Off Off allow_url_fopen On On allow_url_include Off Off always_populate_raw_post_data Off Off arg_separator.input & & arg_separator.output & & asp_tags Off Off auto_append_file no value no value auto_globals_jit On On auto_prepend_file no value no value browscap /etc/browscap.ini /etc/browscap.ini default_charset no value no value default_mimetype text/html text/html define_syslog_variables Off Off disable_classes no value no value disable_functions leak,posix_getpwuid,posix_getpwnam,posix_getgrid,posix_getgrnam,posix_getgroups leak,posix_getpwuid,posix_getpwnam,posix_getgrid,posix_getgrnam,posix_getgroups display_errors Off Off display_startup_errors Off Off doc_root no value no value docref_ext no value no value docref_root no value no value enable_dl Off Off error_append_string no value no value error_log /mnt/Target01/337846/945285/www.dermerrealestate.com/logs/php_errors.log no value error_prepend_string no value no value error_reporting 30711 30711 exit_on_timeout Off Off expose_php Off Off extension_dir /usr/lib64/php/modules /usr/lib64/php/modules file_uploads On On highlight.bg #FFFFFF #FFFFFF highlight.comment #FF8000 #FF8000 highlight.default #0000BB #0000BB highlight.html #000000 #000000 highlight.keyword #007700 #007700 highlight.string #DD0000 #DD0000 html_errors On On ignore_repeated_errors Off Off ignore_repeated_source Off Off ignore_user_abort Off Off implicit_flush Off Off include_path .:/usr/share/pear:/usr/share/php .:/usr/share/pear:/usr/share/php log_errors On On log_errors_max_len 1024 1024 magic_quotes_gpc On On magic_quotes_runtime Off Off magic_quotes_sybase Off Off mail.add_x_header On On mail.force_extra_parameters no value no value mail.log no value no value max_execution_time 30 30 max_file_uploads 20 20 max_input_nesting_level 64 64 max_input_time 60 60 max_input_vars 1000 1000 memory_limit 128M 128M open_basedir no value no value output_buffering no value no value output_handler no value no value post_max_size 8M 8M precision 14 14 realpath_cache_size 4M 4M realpath_cache_ttl 120 120 register_argc_argv On On register_globals Off Off register_long_arrays On On report_memleaks On On report_zend_debug On On request_order no value no value safe_mode Off Off safe_mode_exec_dir no value no value safe_mode_gid Off Off safe_mode_include_dir no value no value sendmail_from no value no value sendmail_path /usr/sbin/sendmail -t -i /usr/sbin/sendmail -t -i serialize_precision 100 100 short_open_tag On On SMTP localhost localhost smtp_port 25 25 sql.safe_mode Off Off track_errors Off Off unserialize_callback_func no value no value upload_max_filesize 8M 8M upload_tmp_dir /tmp /tmp user_dir no value no value user_ini.cache_ttl 300 300 user_ini.filename .user.ini .user.ini variables_order EGPCS EGPCS xmlrpc_error_number 0 0 xmlrpc_errors Off Off y2k_compliance On On zend.enable_gc On On  

I'm now having a problem with PHP uploads on the test site I'm working on.  There is a special page called "cart_import.php" that directs CSV files selected for uploading to the "files" directory in the same location as the the page mentioned, and from there works on updating the website's front end with the data in the CSV file.  But, when I try and upload the file, the page reports that it's failing to receive the upload entirely.  I've confirmed with the host that the php.ini file does allow uploads, the "files" directory is set to write access and upload size allowed is a little over 2MB.  Is there perhaps another thing I'm missing to allow uploads, something that I haven't found yet with Google?

Hello I am trying to make this a multiple file upload. It uploads a 1 file just fine. but I can't get it to upload several. I am a newbie at this. Can you please help me with this script. Thank you.
Code: [Select]
// My form
<form action="upload_file.php" method="post"

<input type="file" name="file" id="file" />
<label for="file">file3:</label>

I need some quick help with this, This is my file upload row loop,
I want to add the if <b>k = 4</b>, then you have reached the maximum upload.
Or something to that Effect.

PRetty much only allowing 4-upload per user, before stoping the upload feature..


row count
Code: [Select]

       <?php

$k = 4;
//$n=5;
for ($i=0, $n=count( $this->songs ); $i < $n; $i++)
//for ($i=0, $n=count( $this->songs ); $i < $n; $i++)
{
$song = &$this->songs[$i];
$checked  = JHTML::_('grid.id',   $i, $song->id );
$link_edit = JRoute::_( 'index.php?userid='.$this->xxx->user_id.'&layout=form&id=' . $song->id .'&from=xxx');
$tick = JHTML::image("images/tick.png",JText::_('Yes'));
$tick_file = JHTML::image("images/tick.png",JText::_('Yes'),array("title" => $xxx->filename));
$cross = JHTML::image("images/publish_x.png",JText::_('No'));
         ?>


End row count


Code: [Select]

<?php
$k = 1 - $k;

I have a form with 2 inputs specific to file uploads (where one day I may add more either through a dynamic layer of adding more than, or just might put 2 or 3 more fields). I can get a single file to upload without issue, but i seem to be having issues trying to get more than one at a time. What is the best way to handle this? I seem to be completely lost on this.

Hi Im building a file hosting script and need to do two things. I have two sets of users FREE and PAID. Both users can upload files to thier own folder, but free users can upload only 2gb of files and paid users can upload 10gb. Is there anyone who could give some pointers on how i can:
 
Allow different folder quotas/sizes for both users 
Stop both users exceeding their quota.
inform them when thier quota is full.

Hope someone can give me help on this

thanks
Lee

Heya guys

The other day i got the error:

[28-Jan-2011 12:07:40] PHP Warning:  POST Content-Length of 16970062 bytes exceeds the limit of 8388608 bytes in Unknown on line 0

Basically this means my server provider doesn't allow the total $_POST data on one page to be above 8MB, and being on shared hosting i cannot fix this   

So, whats the best way to get around this? Ajax?
Options and code samples please

I think this will help a lot of people as i haven't seen many answers after lots of research on the web.

Thanks
Danny.

This is my code

[Page where user uploads files -Edit-Page.php]
<?php
session_start();
if ($_SESSION['adminlogin'] == 1){
//Run
}
else {
header('Location: Log-In.php');
exit;
}
$url = $_POST['url'];

I've been surfing the web and reading various articles, and probably have more questions than answers, so any guidance or direction to resources will (hopefully) be useful.

I'm trying to connect the dots to more adequately understand the security issues within uploading image files.

From its inception, light hits a camera sensor and an image is created. Is it in binary form? ASCII? Other?

Now suppose additional code is added to the image. (For this example, let's say it's a simple script that says Hello - which I suppose would STILL be considered malicious).

If it's simply placed into the image code, how can I open the image (as the recipient) to see the code in its TEXT form?

(I'm assuming that the code would need to be activated either by clicking the script or calling the code in order to actual function)

And if the code is hidden or camouflaged by using an alternate character set, how would it be translated from the unnoticeable character set into something more meaningful in order to perform?
