I have 3 inputs (2 text inputs and 1 file input). All inputs is required.
When I upload a zip file (13MB). I do not get any data from 3 inputs so the validation failed.
I try reduce the file size (6MB) then it's OK.
You need to set the value of upload_max_filesize and post_max_size in your php.ini :
; Maximum allowed size for uploaded files.
upload_max_filesize = 13M
; Must be greater than or equal to upload_max_filesize
post_max_size = 13M
Rather than 13M, I suggest you set it to a little bit bigger like 50 MB.
After modifying php.ini file(s), you need to restart your HTTP server to use new configuration.
If you can't change your php.ini, you're out of luck. You cannot change these values at run-time; uploads of file larger than the value specified in php.ini will have failed by the time execution reaches your call to ini_set.
See the Description of core php.ini directives.

i have simple script for upload files, if i upload file <500Kb everything is working fine, but when i upload bigger file $_FILES['upload']['error'] return me 1.
I know that mean file exceeds the upload_max_filesize, but i set in .htacces php_value post_max_size 999999M and check ini_get('post_max_size') return me 999999M.
But script still don't work with file ~4MB let alone bigger file.
At the end, sorry for my eng (is not main basic lang)
By default, the maximum upload file size for PHP scripts is set to 128 megabytes. However, you may want to change these limits. You can set a limit by changing the upload_max_filesize and post_max_size directives in your php.ini file.
To ensure that file uploads work correctly, the post_max_size directive should be a little larger than the upload_max_filesize. For example, the following settings demonstrate how to set a file upload limit to 20 megabytes:
upload_max_filesize = 20M
post_max_size = 21M
I got the problem with my web server.
I configured PHP to have max upload size 300MB. I changed 2 options in php.ini
php_value upload_max_filesize 300MB
php_value post_max_size 300MB
This works fine.
But recently i noticed very big file in /tmp folder (this is temp folder for PHP).
There were 3 files of a size 1.5GB and continue growing . file names were like temp php files /tmp/php** (** some random code).
And i checked that process writing to these files were my PHP script i created for uploading.
So my question is why PHP upload and post limit didn't affect on these files? What can be the reason? Maybe PHP saves all uploaded data to temp dir first and only after this calculates a size and check if it is good or not?
I appreciate any comments.
UPDATE. Can this be something like - http client sends a request without content-length heder so php can not use post_max_size to limit affect. And PHP writes everything to the disk because doesn't know what is the site of POST request and file in it?
You need to set the value of upload_max_filesize and post_max_size in your php.ini :
; Maximum allowed size for uploaded files.
upload_max_filesize = 300M
; Must be greater than or equal to upload_max_filesize
post_max_size = 300M
or in .htaccess
php_value upload_max_filesize 300M
php_value post_max_size 300M
Try to set a new tmp directory with larger space and no limit rather than the system default (/tmp). You can do so either by changing the default directory in the php.ini file:
upload_tmp_dir = /scratch/custom_temp
or overwrite inside the php script:
<?php
ini_set('upload_tmp_dir', '/scratch/custom_temp');
?>
I had uploaded three files to the server in php. Smaller files are uploaded correctly but
when uploading larger files I get an error.
How to upload large files in php?
If the smaller files are uploaded successfully but not the larger files, then most probably the problem is caused by the php.ini settings.
Did you check what is Maximum allowed size for uploaded files defined in your php.ini file? Find the following line in your php.ini file, there you can define the size. For example:
upload_max_filesize = 10M
You have to set your php.ini to accept larger file size: you are interested in two variables i think:
upload_max_filesize // the max size a file can have when uploaded
max_post_size //the max size of a POST call
Look here for reference
As Nicola points out, there are some variables in the php.ini you should look for:
For example, in php.ini:
memory_limit = 384M
post_max_size = 256M
upload_max_filesize = 200M
What Nicola didn't mention is that constraints may also be in place on your web server. If it's nginx for example, you need to make adjustments to the configuration of your virtual host to support larger files ...
For nginx:
client_max_body_size 150m;
For Apache:
The apache webserver has a LimitRequestBody configuration directive that restricts the size of all POST data regardless of the web scripting language in use. Some RPM installations sets limit request body to 512Kb. You will need to change this to a larger value or remove the entry altogether.
increase the memory limit with .htaccess or ini_set() function in php
I want to change the max upload file limit dynamically. means by not changing the php.ini file on server.
Whenever user had uploaded more then 2 mb then my upload limit should be change.
I want to do all this through php.
Thanks in advance.
The limits enforces by upload_max_filesize are enforced before the php script is run, so the setting cannot be changed dynamically with ini_set.
For more information on the file upload ini settings and where they can be changed, see:
- http://php.net/manual/en/ini.core.php#ini.sect.file-uploads
- http://php.net/manual/en/configuration.changes.modes.php
Assuming by "user" you mean a visitor to your site, there are really only two methods you can enforce such a limit without the file reaching its final destination:
1) Before the upload has occurred: On the client side. You could definitely do this using a java-based uploader. Whether you can get the filesize of the selected file using javascript, I don't know.
2) After the file is uploaded to the server, but before you move it to the final destination (before you run move_uploaded_file)
Try this:
ini_set('upload_max_filesize', your_value_here);
Make sure also that you have specified the correct acceptable settings for:
file_uploads
upload_max_filesize
max_input_time
memory_limit
max_execution_time
post_max_size
If you can't modify your php.ini, you might be able to do it with a .htaccess file:
php_value upload_max_filesize 50M
php_value post_max_size 50M
I can upload small size files with no problem,
but fail when the size is more than 1M.
What's the matter?
You probably need to configure the upload_max_filesize directive, in your php.ini file : PHP will not accept an upload of a file that is bigger than what this directive defines.
And note that you might also need to adjust post_max_size -- which defines the total size of data that can be POSTed (And files upload are sent via POST).
You can also take a look at the Handling file uploads section of the manual, which can give you a couple of useful informations about files upload.
Are you sure you have upload_max_filesize set correctly in php.ini?
Edit you php.ini file to allow for larger uploads.
HERE's some info
You can call echo phpinfo() and then verify your upload_max_filesize and other php environment settings. Its very possible that your script is dying because one of the max limits is being exceeded.
Depending on your environment you can either use ini_set() to change the necessary values at run-time or you can simply edit your php.ini file to set the value permanently. Please note that not all php.ini settings can be changed at run time and if you do edit php.ini, you will need to restart Apache.
As said by others check your php.in for upload_max_filesize and post_max_size settings. If they are okay and if you are using a 3rd party script for uploading, make sure the script is not limiting the max file size by doing something like:
if( $_FILES["file"]["size"] > (1024 * 1024) ) // disallow uploads > 1MB
{
// max size exceeded.
}
