/**
|
|
* This class handles the representation of a file on the filesystem within the framework.
|
|
* Most of the methods also handle the {@link Folder} subclass.
|
|
*
|
|
* Note: The files are stored in the assets/ directory, but sapphire
|
|
* looks at the db object to gather information about a file such as URL
|
|
* It then uses this for all processing functions (like image manipulation).
|
|
*
|
|
* <b>Security</b>
|
|
*
|
|
* Caution: It is recommended to disable any script execution in the "assets/"
|
|
* directory in the webserver configuration, to reduce the risk of exploits.
|
|
* See http://doc.silverstripe.org/secure-development#filesystem
|
|
*
|
|
* <b>Properties</b>
|
|
*
|
|
* - "Name": File name (including extension) or folder name.
|
|
* Should be the same as the actual filesystem.
|
|
* - "Title": Optional title of the file (for display purposes only).
|
|
* Defaults to "Name". Note that the Title field of Folder (subclass of File)
|
|
* is linked to Name, so Name and Title will always be the same.
|
|
* - "Filename": Path of the file or folder, relative to the webroot.
|
|
* Usually starts with the "assets/" directory, and has no trailing slash.
|
|
* Defaults to the "assets/" directory plus "Name" property if not set.
|
|
* Setting the "Filename" property will override the "Name" property.
|
|
* The value should be in sync with "ParentID".
|
|
* - "Content": Typically unused, but handy for a textual representation of
|
|
* files, e.g. for fulltext indexing of PDF documents.
|
|
* - "ParentID": Points to a {@link Folder} record. Should be in sync with
|
|
* "Filename". A ParentID=0 value points to the "assets/" folder, not the webroot.
|
|
*
|
|
* <b>Synchronization</b>
|
|
*
|
|
* Changes to a File database record can change the filesystem entry,
|
|
* but not the other way around. If the filesystem path is renamed outside
|
|
* of SilverStripe, there's no way for the database to recover this linkage.
|
|
* New physical files on the filesystem can be "discovered" via {@link Filesystem::sync()},
|
|
* the equivalent {@link File} and {@link Folder} records are automatically
|
|
* created by this method.
|
|
*
|
|
* Certain property changes within the File API that can cause a "delayed" filesystem change:
|
|
* The change is enforced in {@link onBeforeWrite()} later on.
|
|
* - setParentID()
|
|
* - setFilename()
|
|
* - setName()
|
|
* It is recommended that you use {@link write()} directly after setting any of these properties,
|
|
* otherwise getters like {@link getFullPath()} and {@link getRelativePath()}
|
|
* will result paths that are inconsistent with the filesystem.
|
|
*
|
|
* Caution: Calling {@link delete()} will also delete from the filesystem.
|
|
* Call {@link deleteDatabaseOnly()} if you want to avoid this.
|
|
*
|
|
* <b>Creating Files and Folders</b>
|
|
*
|
|
* Typically both files and folders should be created first on the filesystem,
|
|
* and then reflected in as database records. Folders can be created recursively
|
|
* from sapphire both in the database and filesystem through {@link Folder::findOrMake()}.
|
|
* Ensure that you always set a "Filename" property when writing to the database,
|
|
* leaving it out can lead to unexpected results.
|
|
*
