Expandable.php

<?

1. Converts expandable tables and trees

1. Insert a JS function into the page to be called when show/hide links are clicked

$article = preg_replace( '/(<\\/head\\s*>)/', '<script type="text/javascript"> function toggleExpandable(id) { var content = document.getElementById("expandable-"+id); if (content.style.display == "none") content.style.display = ""; else content.style.display = "none"; this.parent.focus(); } function toggleExpandableTreeItem(id) { var item = document.getElementById("expandable-"+id); if (item.style.display == "none") item.style.display = ""; else item.style.display = "none"; this.parent.focus(); } </script>', $article );

1. Callback function executed for rendering each expandable table

function expandableCallback($matches) { $i = ++$GLOBALS["expandable/tbl-count"]; $open = $matches[2] ?  : ' style="display:none;"'; # default to expanded in id present after title attribute

return '

<td$cs1 align=\"right\">$open<td$cs2>".$items[2][$row];

}

return '<table '.$matches[2].$tree.'

<a class=expandable-link href="javascript:toggleExpandable('.$i.')">► '.$matches[1].'</a>	<a href="'.$GLOBALS['xwScript'].'?title='.$matches[1].'&action=edit"></a>
'.$matches[3].' '; } Callback function executed for rendering each expandable table function expandableTreeCallback($matches) { $id = ++$GLOBALS["expandable/tbl-count"]; $tree = ; if (preg_match_all('/^(\\*+)\\s*(.+)\\s*$/m',$matches[3],$items)) { foreach ($items[1] as $row => $indent) { $depth = strlen($indent); $cs1 = $depth > 1 ? ' colspan="'.($depth-1).'"' : ; $cs2 = ' colspan='.(20-$depth); $open = strlen($items[1][$row+1]) > $depth ? '+' : ; $tree .= "
F

';

} return $matches[0]; }

1. Replace all the expandable tables with html containing CSS classes and the show/hide links

$article = preg_replace_callback(

'/

(.+?<\\/table\\s*?>)/s', 'expandableCallback', $article );

1. Replace all the expandable tree-views

$article = preg_replace_callback( '/(<div)\\s+(class=["\']?expandable-tree["\']?.+?\\s*>)(.+?)(<\\/div\\s*?>)/s', 'expandableTreeCallback', $article ); ?>
