# getAssetUrl()

View source (opens new window)

Arguments

  • $bundle
  • $asset
  • $appendTimestamp

# getCacheKeyForPathHash()

Get the cache key for a given asset hash

View source (opens new window)

Arguments

Returns

string (opens new window)

# getPublishedUrl()

Returns the URL of a published file/directory path.

View source (opens new window)

Arguments

Returns

string (opens new window), false (opens new window) – 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 (opens new window) 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 will NOT be published.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.

View source (opens new window)

Arguments

  • $path (string (opens new window)) – The asset (file or directory) to be published

  • $options (array (opens new window)) – 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 (opens new window) if set.

  • afterCopy: callback, a PHP callback that is called after a sub-directory or file is successfully copied. This overrides afterCopy (opens new window) 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 (opens new window) if set.

Returns

array (opens new window) – The path (directory or file path) and the URL that the asset is published as.

Throws
