<!-- Pod2Wiki=item_upload_archive --></div>
 +
===$success = $doc-&gt;upload_archive( $filehandle, $filename, $archive_format )===
 +
 
 +
Upload the contents of the given archive file. How to deal with the  archive format is configured in SystemSettings.
 +
 
 +
(In case the over-loading of the word "archive" is getting confusing,  in this context we mean ".zip" or ".tar.gz" archive.)
 +
 
 +

<!-- Pod2Wiki=item_add_archive --></div>
 +
===$success = $doc-&gt;add_archive( $file, $archive_format )===
 +
 
 +
$file is the full path to an archive file, eg. zip or .tar.gz
 +
 
 +
This function will add the contents of that archive to the document.
 +
 
 +

<!-- Pod2Wiki=item_add_directory --></div>
 +
===$success = $doc-&gt;add_directory( $directory )===
 +
 
 +
Upload the contents of $directory to this document. This will not set the main file.
 +
 
 +
This method expects $directory to have a trailing slash (/).
 +
 
 +
<div style='background-color: #eef; margin: 0.5em 0em 1em 0em; border: solid 1px #cce;  padding: 0em 1em 0em 1em; font-size: 80%; '>

<!-- Pod2Wiki=item_upload_url --></div>
 +
===$success = $doc-&gt;upload_url( $url )===
 +
 
 +
Attempt to grab stuff from the given URL. Grabbing HTML stuff this way is always problematic, so (by default): only relative links will  be followed and only links to files in the same directory or  subdirectory will be followed.
 +
 
 +
This (by default) uses wget. The details can be configured in SystemSettings.

DESCRIPTION

Document represents a single format of an EPrint (eg. PDF) - the actual file(s) rather than the metadata.

This class is a subclass of DataObj, with the following metadata fields:

User Comments


docid (text)

The unique ID of the document. This is a string of the format 123-02 where the first number is the eprint id and the second is the document number within that eprint.

This should probably have been and "int" but isn't. I later version of EPrints may change this.

User Comments


eprintid (itemref)

The id number of the eprint to which this document belongs.

User Comments


placement (int)

Placement of the document - the order documents should be shown in.

User Comments


format (namedset)

The format of this document. One of the types of the dataset "document".

User Comments


formatdesc (text)

An additional description of this document. For example the specific version of a format.

User Comments


language (namedset)

The ISO ID of the language of this document. The default configuration of EPrints does not set this.

User Comments


security (namedset)

The security type of this document - who can view it. One of the types of the namedset "security".

User Comments


content (namedset)

The type of content. Conceptual type, no format. ie. Supporting Material or published version. Values from namedset "content"

User Comments


license (namedset)

The type of license for the document. Such as GFDL or creative commons. Values from namedset "licenses"

User Comments


main (text)

The file which we should link to. For something like a PDF file this is the only file. For an HTML document with images it would be the name of the actual HTML file.

User Comments


documents (subobject, multiple)

A virtual field which represents the list of Documents which are part of this record.

METHODS

User Comments


$newdoc = $doc->clone( $eprint )

Attempt to clone this document. Both the document metadata and the actual files. The clone will be associated with the given EPrint.

User Comments


$eprint = $doc->get_eprint

Return the EPrint this document is associated with.

This is a synonym for get_parent().

User Comments


$boolean = $doc->is_public()

True if this document has no security set and is in the live archive.

User Comments


$url = $doc->get_url( [$file] )

Return the full URL of the document.

If file is not specified then the "main" file is used.

User Comments


$path = $doc->local_path

Return the full path of the directory where this document is stored in the filesystem.

User Comments


%files = $doc->files

Return a hash, the keys of which are all the files belonging to this document (relative to $doc->local_path). The values are the sizes of the files, in bytes.

User Comments


$success = $doc->remove_file( $filename )

Attempt to remove the given file. Give the filename as it is returned by get_files().

User Comments


$success = $doc->remove_all_files

Attempt to remove all files associated with this document.

User Comments


$doc->set_main( $main_file )

Sets the main file. Won't affect the database until a $doc->commit().

This checks the file exists, so is more than an alias for get_value.

User Comments


$success = $doc->upload( $filehandle, $filename [, $preserve_path [, $filesize ] ] )

Upload the contents of the given file handle into this document as the given filename.

If $preserve_path then make any subdirectories needed, otherwise place this in the top level.

User Comments


$success = $doc->add_file( $file, $filename, [$preserve_path] )

$file is the full path to a file to be added to the document, with name $filename.

If $preserve_path then keep the filename as is (including subdirs and spaces)

User Comments


$success = $doc->upload_archive( $filehandle, $filename, $archive_format )

Upload the contents of the given archive file. How to deal with the archive format is configured in SystemSettings.

(In case the over-loading of the word "archive" is getting confusing, in this context we mean ".zip" or ".tar.gz" archive.)

User Comments


$success = $doc->add_archive( $file, $archive_format )

$file is the full path to an archive file, eg. zip or .tar.gz

This function will add the contents of that archive to the document.

User Comments


$success = $doc->add_directory( $directory )

Upload the contents of $directory to this document. This will not set the main file.

This method expects $directory to have a trailing slash (/).

User Comments


$success = $doc->upload_url( $url )

Attempt to grab stuff from the given URL. Grabbing HTML stuff this way is always problematic, so (by default): only relative links will be followed and only links to files in the same directory or subdirectory will be followed.

This (by default) uses wget. The details can be configured in SystemSettings.

User Comments


new_window => 1

User Comments


preview => 1

User Comments

User Comments
