PHP See Only 20 Uploading Files at a Time

Max file number can php upload at same time

This limit was added in PHP 5.3.1, to avoid a type of DOS attack: temporary files exhaustion.

Added "max_file_uploads" INI directive, which can be set to limit the number of file uploads per-request to 20 by default, to prevent possible DOS via temporary file exhaustion. (Ilia)

(changelog for PHP 5.3.1)

You can increase this limit by changing the max_file_uploads directive.

only 20 images are uploaded

Your php.ini is restricting to max 20 POST elements. Change max_file_uploads=20 to higher value.

Laravel Multiple Uploading Only Inserts 20 into DB

You might need to change your PHP settings to allow for larger uploads. PHP has limits on file upload size, POST size etc

Go to : /etc/php5/fpm/php.ini or /etc/php/7.0/fpm/php.ini or if you are using Apache /etc/php/7.0/apache2/php.iniand change these values.

post_max_size = 125M 

upload_max_filesize = 100M 

max_file_uploads = 20

to a higher value. where post_max_size is the maximum size of an entire POST upload_max_filesize is the max size of an individual size and max_file_uploads is the maximum limit of files you can upload at a time.

HTML Input: uploading multiple files maxes at 20

I'm a bit confused by the 'wont upload more than 20' part... what are you basing this on? You're getting an error either way it seems.

Change your for loop to check for isset($image['name'][$i]) instead, and you will no longer get an error.

for($i = 0; isset($image['name'][$i]); $i++)
{
    //code
}

As mentioned by yes123, you risk hitting the maximum POST size and should check php.ini.

Multiple file upload limit

In your php ini file, max_file_uploads shows maximum number of files allowed to be uploaded simultaneously. By default 20 files are allowed. Use below code to set maximum file upload limit.

ini_set('max_file_uploads',1000);
