Type: Feature Addition


PageDeleteHandler @ WakkaWiki

Added the ability for admin users to delete pages.

Create a file named "delete.php" with the following code and place it in your /handlers/page directory. You can access it by putting a "/delete" after any URL, provided you are the page owner.

This will permanently delete the current page, plus all comments on that page including those made by other users. It cannot be undone.

<div class="page">

if ($this->UserIsOwner())
    if ($_POST)
        $tag = $this->GetPageTag();
        //  delete the page
        // delete from wakka_pages where tag=
        // delete from wakka_links where from_tag =
        // delete from wakka_acls where page_tag =
        // delete from wakka_referrers where page_tag =
        $delResult = $this->LoadSingle("delete from ".$this->config["table_prefix"]."pages where tag = '".mysql_escape_string($tag)."'");
        $delResult = $this->LoadSingle("delete from ".$this->config["table_prefix"]."links where from_tag = '".mysql_escape_string($tag)."'");
        $delResult = $this->LoadSingle("delete from ".$this->config["table_prefix"]."acls where page_tag = '".mysql_escape_string($tag)."'");
        $delResult = $this->LoadSingle("delete from ".$this->config["table_prefix"]."referrers where page_tag = '".mysql_escape_string($tag)."'");

        // also delete comments from the page
        // this is messy, because comments have acls, so we have to find the comment names and delete those too

        // finds comments for this page
        $comments = $this->LoadComments($this->tag);

        //  delete the acls for each comment
        if ($comments)
            foreach ($comments as $comment)
                $delResult = $this->LoadSingle("delete from ".$this->config["table_prefix"]."acls where page_tag = '".mysql_escape_string($comment["tag"])."'");
        // finally delete the comments themselves
        // delete from wakka_pages where comment_on= the current page
        $delResult = $this->LoadSingle("delete from ".$this->config["table_prefix"]."pages where comment_on = '".mysql_escape_string($tag)."'");

        $message = "Page has been deleted ";

        // redirect back to main page
        // show form
        <h3>Delete <?php echo $this->Link($this->GetPageTag()) ?></h3>
        <br />
        <?php echo $this->FormOpen("delete") ?>
        <table border="0" cellspacing="0" cellpadding="0">
                <td>Completely delete this page, including all comments?</td>
                <td> <!-- nonsense input so form submission works with rewrite mode --><input type="hidden" value="" name="null"><input type="submit" value="Delete Page"  style="width: 120px"   />
                <input type="button" value="Cancel" onClick="history.back();" style="width: 120px" /></td>
    print("<em>You're not the owner of this page.</em>");

There are no comments on this page.
