I created a very simple Blog Action for my personal website.
Here is actions/blog.php:
<?php
if (!isset($name))
{
print "<span class='error'>You need to include \"name=\" when using the blog action.</span>";
}
else if ($pages = $this->LoadBlogEntries($name))
{
$curday = "";
if ($user = $this->GetUser()) {
$max = $user["changescount"];
} else {
$max = 50;
}
foreach ($pages as $i => $page)
{
if (($i < $max) || !$max)
{
// day header
list($day, $time) = explode(" ", $page["firsttime"]);
if ($day != $curday)
{
if ($curday) print("</span><br />\n");
print("<strong>$day:</strong><br />\n<span class=\"recentchanges\">");
$curday = $day;
}
// Begin entry
$pagetag = $page["tag"];
// Print Title. Strip "Blog" from page tag and add spaces.
print "<h1>".$this->BeautifyTitle($pagetag)."</h1><br />\n";
// I used Dreck Fehler's include action code here.
$pagename = strtolower($pagetag);
if (!$this->config["includes"]) $this->config["includes"][] = strtolower($this->tag);
if (!in_array($pagename, $this->config["includes"]) && $pagename != $this->tag) {
if ($this->HasAccess("read", $pagename)) {
$this->config["includes"][] = $pagename;
$blogpage = $this->LoadPage($pagename);
print $this->Format($blogpage["body"]);
}
} else print "<span class='error'>Circular reference detected</span>";
}
print "<br /><br />\n";
}
}
?>
if (!isset($name))
{
print "<span class='error'>You need to include \"name=\" when using the blog action.</span>";
}
else if ($pages = $this->LoadBlogEntries($name))
{
$curday = "";
if ($user = $this->GetUser()) {
$max = $user["changescount"];
} else {
$max = 50;
}
foreach ($pages as $i => $page)
{
if (($i < $max) || !$max)
{
// day header
list($day, $time) = explode(" ", $page["firsttime"]);
if ($day != $curday)
{
if ($curday) print("</span><br />\n");
print("<strong>$day:</strong><br />\n<span class=\"recentchanges\">");
$curday = $day;
}
// Begin entry
$pagetag = $page["tag"];
// Print Title. Strip "Blog" from page tag and add spaces.
print "<h1>".$this->BeautifyTitle($pagetag)."</h1><br />\n";
// I used Dreck Fehler's include action code here.
$pagename = strtolower($pagetag);
if (!$this->config["includes"]) $this->config["includes"][] = strtolower($this->tag);
if (!in_array($pagename, $this->config["includes"]) && $pagename != $this->tag) {
if ($this->HasAccess("read", $pagename)) {
$this->config["includes"][] = $pagename;
$blogpage = $this->LoadPage($pagename);
print $this->Format($blogpage["body"]);
}
} else print "<span class='error'>Circular reference detected</span>";
}
print "<br /><br />\n";
}
}
?>
Here are the changes I made to wikka.php:
function LoadPagesLinkingFrom($tag) { return $this->LoadAll("select to_tag as tag from ".$this->config["table_prefix"]."links where from_tag = '".mysql_real_escape_string($tag)."' order by tag"); }
function LoadBlogEntries($tag)
{
//Get pages linking to Blog entry list page and form part of query string
$blogPages = $this->LoadPagesLinkingFrom($tag);
if (count($blogPages) == 0)
{
return false;
}
$i = 0;
$queryString = "";
foreach ($blogPages as $blogPage)
{
$i++;
if ($i < count($blogPages))
{
$queryString .= "\"".$blogPage["tag"]."\", ";
}
else
{
$queryString .= "\"".$blogPage["tag"]."\"";
}
}
if ($pages = $this->LoadAll("select min(entry2.id) as firstid, min(entry2.time) as firsttime, entry1.* from ".$this->config["table_prefix"]."pages entry1, ".$this->config["table_prefix"]."pages entry2 where entry1.tag = entry2.tag and entry1.tag in (".$queryString.") and entry1.latest ='Y' group by entry1.tag order by firstid desc"))
{
foreach ($pages as $page)
{
$this->CachePage($page);
}
return $pages;
}
}
function BeautifyTitle($title)
{
/*
* I scarfed this function from John Greenway's JSPWiki page
* http://www.jspwiki.org/Wiki.jsp?page=JohnGreenaway
*/
$result = "";
for($i = 0; $i <= strlen($title); $i++)
{
if(ctype_upper($title[$i]) && ($i > 0))
{
if (($i < (strlen($title) - 1) && ctype_lower($title[$i+1])) || ctype_lower($title[$i-1])) {
$result.=' ';
}
}
$result.= $title[$i];
}
return $result;
}
