I created a very simple Blog Action for my personal website. To insert a Blog on a page, I insert {{blog name="EntryListPage"} where EntryListPage is a page containing A list of pages. Each wiki page on the entry page is included as an entry in the Blog. To edit an entry, you simply edit the page that corresponds to the entry.
I thought about making EntryListPage a Category, but I didn't want the Category wikiname appearing in the entries.
I also tried marking a page as a Blog entry if it's wikiname began with Blog. That restricted me to only one blog per wiki, though.
Maybe someone will find this useful. (Or maybe someone will find a better way to do it. Either way...) 8^)
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 additions I made to wikka.php:
<?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 $result;
}
?>
function LoadPagesLinkingFrom($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 = "";

{
$i++;

{

}

}
}

{
foreach ($pages as $page)
{
$this->CachePage($page);
}
return $pages;
}
}
function BeautifyTitle($title)
{
/*

*/
$result = "";
for($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;
}
?>
