Member Function Documentation

close_output()

dataformat_pdf\writer::close_output

(

)

Write the end of the file.

Reimplemented from core\dataformat\base.

close_output_to_file()

dataformat_pdf\writer::close_output_to_file

(

)

Write data to disk.

Return values

bool

Reimplemented from core\dataformat\base.

close_sheet()

core\dataformat\base::close_sheet (   $columns )

inherited

Write the end of the sheet containing the data.

Parameters

array

$columns

Reimplemented in dataformat_html\writer, and dataformat_json\writer.

export_html_image_source()

dataformat_pdf\writer::export_html_image_source ( \stored_file  $file )

protected

When exporting images, we need to return their Base64 encoded content.

Otherwise TCPDF will create a HTTP request for them, which will lead to the login page (i.e. not the image it expects) and throw an exception

Note: ideally we would copy the file to a temp location and return it's path, but a bug in TCPDF currently prevents that

Parameters

stored_file

$file

Return values

string|null

Reimplemented from core\dataformat\base.

format_record()

core\dataformat\base::format_record (   $record )

protectedinherited

Apply formatting to the cells of a given record.

Parameters

array | stdClass

$record

Return values

array

get_extension()

core\dataformat\base::get_extension ( )

inherited

Get the file extension.

Return values

string

file extension

replace_pluginfile_images()

core\dataformat\base::replace_pluginfile_images ( ?string  $content )

protectedinherited

We need to locate all img tags within a given cell that match pluginfile URL's.

Partly so the exported file will show the image without requiring the user is logged in; and also to prevent some of the dataformats requesting the file themselves, which is likely to fail due to them not having an active session

Parameters

string | null

$content

Return values

string

send_http_headers()

dataformat_pdf\writer::send_http_headers

(

)

Output file headers to initialise the download of the file.
