getAssetUrl() ​
Arguments ​
$bundle$asset$appendTimestamp
getCacheKeyForPathHash() ​
Get the cache key for a given asset hash
Arguments ​
$hash(string)
Returns ​
getPublishedUrl() ​
Returns the URL of a published file/directory path.
Arguments ​
$path(string) – Directory or file path being published$publish(boolean) – Whether the directory or file should be published, if not already$filePath(string, null) – A file path, relative to $sourcePath if $sourcePath is a directory, that should be appended to the returned URL.
Returns ​
string, false – The published URL for the file or directory, or false if $publish is false and the file or directory does not exist
publish() ​
Publishes a file or a directory.
This method will copy the specified file or directory to basePath so that it can be accessed via the Web server.
If the asset is a file, its file modification time will be checked to avoid unnecessary file copying.
If the asset is a directory, all files and subdirectories under it will be published recursively. Note, in case $forceCopy is false the method only checks the existence of the target directory to avoid repetitive copying (which is very expensive).
By default, when publishing a directory, subdirectories and files whose name starts with a dot "." will NOT be published. If you want to change this behavior, you may specify the "beforeCopy" option as explained in the $options parameter.
Note: On rare scenario, a race condition can develop that will lead to a one-time-manifestation of a non-critical problem in the creation of the directory that holds the published assets. This problem can be avoided altogether by 'requesting' in advance all the resources that are supposed to trigger a 'publish()' call, and doing that in the application deployment phase, before system goes live. See more in the following discussion: https://code.google.com/archive/p/yii/issues/2579
Arguments ​
$path(string) – The asset (file or directory) to be published$options(array) – The options to be applied when publishing a directory. The following options are supported:only: array, list of patterns that the file paths should match if they want to be copied.
except: array, list of patterns that the files or directories should match if they want to be excluded from being copied.
caseSensitive: boolean, whether patterns specified at "only" or "except" should be case sensitive. Defaults to true.
beforeCopy: callback, a PHP callback that is called before copying each sub-directory or file. This overrides beforeCopy if set.
afterCopy: callback, a PHP callback that is called after a sub-directory or file is successfully copied. This overrides afterCopy if set.
forceCopy: boolean, whether the directory being published should be copied even if it is found in the target directory. This option is used only when publishing a directory. This overrides forceCopy if set.
Returns ​
array – The path (directory or file path) and the URL that the asset is published as.
Throws ​
- yii\base\InvalidArgumentException
if the asset to be published does not exist. - yii\base\InvalidConfigException
if the target directory basePath is not writeable.
