I am writing a PHP script to upload and re-size 4 images.
I have opted to use the method of giving 4 inputs the same name (an array):
<input type="file" name = "userfile[]" id="file1" />
<input type="file" name = "userfile[]" id="file2" />
<input type="file" name = "userfile[]" id="file3" />
<input type="file" name = "userfile[]" id="file4" />
I have set max_upload_filesize in wamp to 50M.
I have verified the max_uploads is set to default (20).
I have restarted all services and run php_info to verify this php.ini file was loaded.
My form-receiver page only does one thing:
var_dump($_FILES["userfile"]);
This works well, until file size approaches 8MB.
When the size of the uploaded files approache 8MB I get the error
Notice: Undefined index: userfile in C:\wamp\www\uploader\file_upload.php on line 2
I have re-sized one image, pushing it up to 8MB size, and then tried ot upload 1 single file- this recreates the error. I am certain that an 8MB limit exists here.
Can anyone help me solve this?
Find post_max_size and increase it's value.
Also, it's upload_max_filesize, not max_upload_filesize.

I changed post_max_size = 100M, max_file_size was already 64M. Problem is when I run the code and upload more than 20kb then first time it gives error no. 3 (partial upload problem) and then stop working. I have to restart php to do other thing. Please help..
In your php.ini file, change this variable upload_max_filesize to whatever max_uploaded_size you wish to have.
But remember, to keep your post_max_size greater than or equal to upload_max_filesize.
For more info, see this answer.
PHP change the maximum upload file size
I've following HTML code to upload image file :
<form id="request_form" method="post" enctype="multipart/form-data" action="print.php">
<input type="file" name="student_image" id="student_image" accept="image/*" capture/>
<button type="submit">Submit</button>
</form>
PHP code is as follows :
<?php
print_r($_FILES);// Here I'm getting blank $_FILES array for few specific image files which are greater than 10 MB in size
?>
Following are the file upload setting from my php.ini file:
upload_max_filesize = 10M
post_max_size = 10M
I'm getting the blank array when I try to upload image files which are greater than 10 MB in size.
Please help me out from this issue.
You need to change your php.ini file and set greater value than 10M, it is config for Apache, and Apache doesn't let you to send big image and files before it
I'm coding a web application and I need to be able to upload a CV. I have done my homework and tried everything I can find but I keep getting the same issue. In my PHP Script the $_FILES array is completely empty and the CV field is being sent to the $_POST array. My form big so I will just post the important code.
<form enctype="multipart/form-data" action="exec/register_user.php" method="post">
<input type="file" name="cv" id="cv"/>
<input type='submit' value='Register' />
</form>
Then I don't think it will help you with anything by posting the PHP code. But if i var_dump($GLOBALS), it shows that the $_FILES array is empty but 'cv' shows as a string in the $_POST array.
Any help will be appreciated.
Thanks in advance!
This is normally caused by the uploaded file being too large and exceeding one of teh 2 defined upload limits. post_max_size or upload_max_filesize
You may be able to override these values in the .htaccess file if you have the right permissions to do so by adding teh following 2 lines.
php_value post_max_size 20M
php_value upload_max_filesize 20M
Would allow uploading of files upto 20 MB
You are missing the hidden field max_file_size, required by PHP.
<!-- MAX_FILE_SIZE must precede the file input field -->
<input type="hidden" name="MAX_FILE_SIZE" value="20000000" />
See the explanation here.
so I am the webmaster/in charge collecting the files for a music video contest. The problem is I only know HTML, CSS, limited PHP, and some Actionscript 2. I need to be able to allow people to upload large files to my server (the videos they are submitting) but I am unable to find a way to do that. I was wondering if anyone had any suggestions of an upload system that work work for me. I have tired PHP's ftp_put but the files seem to be too large for it to handle. Thanks
I'm not sure if this will work for very large files, but I do some image uploading using a form and file inputs like so:
HTML
<form method="post" action="upload.php">
<input type="file" name="file" />
</form>
PHP
move_uploaded_file($_FILES['file']['tmp_name'], $server_path . $new_file_name);
You can also upload multiple files like so:
HTML
<form method="post" enctype="multipart/form-data" action="upload.php">
<input type="file" name="files[]" />
<input type="file" name="files[]" />
<input type="file" name="files[]" />
</form>
PHP
for ($i = 0; $i < count($_FILES['images']['error']); $i++)
{
move_uploaded_file($_FILES['file']['tmp_name'][$i], $server_path . $new_file_name[$i]);
}
I know for example youtube, as well as facebook have a process that uploads the files by parts ... but I don't know how it happens.
Another way would be to create an ftp account for each user and then they can use a program like filezila.
The other way, I think it would be an application in Java.
large files can also be handled by ftp_put, check your settings for upload_max_filesize, post_max_size, max_execution_time, max_input_time, and memory_limit in your php.ini file. These could all affect your file uploading abilities.
The problem with PHP uploading is that typically there's a file size limit and there's a server timeout limit as well, as in if the script is running for so long, it will time out. This becomes a problem in uploading larger files. If you can modify these settings yourself on your server then I suggest you try SWFUpload
My HTML form is like
<input type="hidden" name="MAX_FILE_SIZE" value="20000" />
<input type="file" name="userfile" id="userfile" size="50" />
However, when I upload a file of 3mb, it gives error that:
Problem: File exceeded max_file_size"
Last I checked, MAX_FILE_SIZE was in bytes. 3MB is equal to either 3,000,000 or 3,145,728 (depending on unit convention), both of which are significantly higher than the 20,000 you specified.
edit the php.inihelp: http://www.cyberciti.biz/faq/linux-unix-apache-increase-php-upload-limit/
You may want to increase the value of the max file size.
<input type="hidden" name="MAX_FILE_SIZE" value="67108864" />
You will also need to update the php.ini file with the following values to allow up to 64MB files:
memory_limit = 96M
post_max_size = 64M
upload_max_filesize = 64M
