Drupal 7 Set Separate File Upload Limits

The File module enables you lot to upload and adhere files to content and to manage these uploads if you take the appropriate permissions. This module is responsible for validating file content and managing uploaded files. It also provides options for displaying file content.

Every bit a site ambassador, y'all will exist able to control what type of files tin can be uploaded and their maximum size.

The File module provides its functionality past defining a File field type for the Field module. File attachments are defined at the content type level (or other entities). To learn how to define a field and add together it to a content type, see Working with Field UI.

Uses

Adding a file field to a content type

Navigate to the "Manage fields" tab of the content blazon to which you wish to add together the file field ( Administer > Construction > Content types , and the link manage fields for your specific content type).

Select the field type file, give the field a label and machine proper name, click-and-drag it to the place you desire to have it amongst your fields, and hitting the save button.

Equally when adding whatever new field, you are first required to set the field specific settings. These employ for all places where yous use the field. These cannot be changed per entity.

• When checked, the Enable Display field pick allows users to cull if a file should be shown when viewing the content.
• The Files displayed by default option makes the display file option checked by default, when users upload files to this field.
• The Upload destination by default only has the public files option bachelor – making the files bachelor correct from the server (without Drupal checking any access). If y'all want to use private files, you must first change some settings at the file system administration page (Administer > Configuration > Media: File system). Run across below for details.

The adjacent step is to set the field settings for this instance only. This can be changed between different content types (or other entities).

You can add validation options for the File field when yous configure the content type. You lot must list all of the file extensions that the last user will need to be able to upload. The optional file directory where the files will be uploaded is a sub-directory of the file system path defined in the file system administration page (Administer > Configuration > Media: File arrangement). Y'all may specify a maximum file size for each file uploaded.

Managing attachment display

One time a file has been attached to content, you can specify whether it will exist displayed in the list of attached files or non. Listed files are displayed automatically in a section at the bottom of the content; not-listed files tin for example be embedded in your content, but are not included in the list. (Embedding a file in your content means you copy the path of the file and manually embed it where yous desire, for example, to insert in the content as a link tag. Notation that the text format "Filtered HTML" past default refuses any image tags..)

Additional options for managing the display of the file list are bachelor in the "Manage display" tab of the specific content type'southward assistants page (Administrate > Structure > Content types and the link field display for your content type).

Managing file locations and access

When yous create a file field, you can specify the sub-directory of the site's file system where uploaded files for this content type will be stored. The site's file system paths are defined on the File system folio (Administer > Configuration > Media: File system).

Y'all can besides specify whether files are stored in a public directory or in a private file storage area. Files in the public directory tin be accessed straight through the spider web server; when public files are listed, direct links to the files are used and anyone who knows a file's URL can download the file. Files in the private directory are not accessible directly through the spider web server; when private files are listed, the links are Drupal path requests (for instance, "/arrangement/files/name-of-the-file.pdf"; hither, "system/files/" is not an actual binder in the filesystem whose contents are served by the web server, just instead is a virtual URL managed past Drupal through which the private files tin can be downloaded). This adds to server load and download time, since Drupal must resolve the path for each file download request, merely allows for access restrictions to be added.

The all-time practise for public files is to shop them in the multi-site directory like:

          sites/default/files                  

The default way to deeply add a private directory for your files is to use a directory that can not be accessed straight past your web server, but can be accessed by Drupal. Ideally this directory should be located outside of your Drupal root folder.

The unproblematic way to add together a private directory for your files is to create a sub-directory under the public directory like:

          sites/default/files/private                  

When you specify the private directory in admin/config/media/file-system it volition automatically create the sub-directory & create a simple .htaccess file with Deny from all. This stops Apache from serving files from this directory. Make sure that you examination this by adding a file to that directory and verifying that you tin't browse there directly. If this isn't working, all files in this directory volition be accessible to anyone who can guess the URL! Notation that not-Apache web servers may need additional configuration to secure private file directories.

Whenever possible it'south recommended that yous choose a directory located exterior of your Drupal root folder (or actually outside your spider web root), which may be tricky if you lot are on a shared host. If you do have admission though, y'all can choose a individual directory which will be on the aforementioned level as your web root directory (often called public_html or www or similar) using:

          ../private                  

Accessing Private Files

Information technology is important to empathize that just because a file field is configured to use the private file system, that does non mean Drupal will prevent anyone from viewing files uploaded via that field. The files volition be served by Drupal (via a URL like "/arrangement/files/proper name-of-the-file.pdf"), only Drupal will merely block users' access to download the file via that URL if there is a specific reason to do so.

For example: you take created a new content type with a file field which stores files in your site's private file directory. Next yous create a node from this new content type and adhere two new files. When the node is published links to both attached files are visible and anyone who tin can view the node may download the files. Now, if you unpublish the node so that your site'due south end users can no longer access it, all attached files get inaccessible for download by those users also, even if they use the direct link to the files that worked when the node was published.

For finer grained control of who can run across/download attached files yous will demand an additional admission control module. You lot may write a module yourself, or use a contributed module such every bit Content Access.

Private file arrangement settings in Drupal 8

In Drupal 8, you can no longer ready private file system via UI. You lot set it in your settings.php file. Search for this line in your settings.php:

          # $settings['file_private_path'] = '';                  

add the url path to your private directory. Information technology must exist outside of your spider web root directory and be an absolute path, for example /var/www/html/example.org/private with web root in/var/www/html/example.org/spider web or /home/username/example.org/private with spider web root in /home/username/example.org/web. And then it should look similar:

          $settings['file_private_path'] = $app_root . '/../individual';                  

Technical Details

PHP configuration

For file uploads to work, PHP must be configured properly. The following PHP configuration variables may need to be fix or configured, in your PHP php.ini file, .htaccess file, or settings.php files.

• file_uploads = On must be set to "On"
• upload_max_filesize = 24M can't exist larger than post_max_size
• max_input_time = 300 pocket-size values may crusade timeouts for large file uploads
• memory_limit = 64M modest values may cause out of memory errors for large file uploads
• max_execution_time = 180 small-scale values may cause timeouts for big file uploads
• post_max_size = 24M limits the size of input submitted to the website (including attached files)

Superlative Tip: Make sure you're editing the correct php.ini file by going to YOURSITE/admin/reports/status/php. This will brandish information about your current PHP setup which is existence used for Drupal (in essence it'due south running phpinfo()). Now look for the 'Loaded Configuration File' department, this volition list the php.ini file you need to edit.

Immigration the Cache

It is recommended y'all clear the enshroud after making these updates. If you don't, then Drupal is likely to complain that the private files area is not protected.
