Essentially the script takes three arguments; a site, a story id and an output format. I slurp the whole story into an associative array - using htmlpurifier as it's brought in - and output using the desired format.
For epub the .opf is created using this
PHP Code:
/******************************************************************************
CONTENT.OPF
******************************************************************************/
// create info for XML
$manifest = '';
$spine = '';
for ($i=1;$i<=$story['chapter_count'];$i++)
{
$id = sprintf('%03d', $i);
$manifest .= ' <item id="chapter-' . $id . '" href="chapter-' . $id . '.xhtml" media-type="application/xhtml+xml"/>' . "\n";
$spine .= ' <itemref idref="chapter-' . $id . '"/>' . "\n";
}
$story_title = $story['title'];
// add the OPF info
$opf = <<<EOM
<{$qm}xml version="1.0"{$qm}>
<package xmlns="http://www.idpf.org/2007/opf" unique-identifier="bookid" version="2.0">
<metadata xmlns:dc="http://purl.org/dc/elements/1.1/">

<manifest>
<item id="ncx" href="toc.ncx" media-type="application/x-dtbncx+xml"/>
<item id="cover" href="cover.xhtml" media-type="application/xhtml+xml"/>
{$manifest}
<item id="backcover" href="backcover.xhtml" media-type="application/xhtml+xml"/>
</manifest>
<spine toc="ncx">
<itemref idref="cover"/>
{$spine}
<itemref idref="backcover"/>
</spine>
</package>
EOM;
$epub->add_file($opf, 'OEBPS/content.opf', $tstamp);
and the toc is created using
PHP Code:
/******************************************************************************
TOC.NCX
******************************************************************************/
// create info for XML
$navpoint = '';
for ($i=1;$i<=$story['chapter_count'];$i++)
{
$id = sprintf('%03d', $i);
$iplus = $i + 1;
$chapter_title = $story['chapters'][$i]['title'];
$navpoint .= <<<EOM
<navPoint id="navpoint-{$iplus}" playOrder="{$iplus}">
<navLabel>
<text>{$chapter_title}</text>
</navLabel>
<content src="chapter-{$id}.xhtml"/>
</navPoint>
EOM;
}
$iplus = $i + 1;
//
$toc = <<<EOM

The .oeb script takes the same associative array and outputs the flat .oeb file with the mime wrapping, building the .opf part the same way. This .oeb script was intended to create files suitable for upload to the eBookwise personal content server.
