<h2>Edit Permalink Structure</h2>
<p>WordPress offers you the ability to create a custom URI structure for your permalinks and archives. The following &#8220;tags&#8221; are available:</p>
<ul>
<li><code>%year%</code> --- The year of the post, 4 digits, for example <code>2004</code> </li>
<li><code>%monthnum%</code> --- Month of the year, for example <code>05</code></li>
<li><code>%day% </code>--- Day of the month, for example <code>28</code></li>
<li><code>%postname%</code> --- A sanitized version of the title of the post. So &quot;This Is A Great Post!&quot; becomes &quot;<code>this-is-a-great-post</code>&quot; in the URI </li>
<li><code>%post_id%</code> --- The unique ID # of the post, for example <code>423</code> <strong></strong></li>
</ul>
<p>So for example a value like </p>
<p><code>/archives/%year%/%monthnum%/%day%/%postname%/</code> </p>
<p>would give you a permalink like </p>
<p><code>/archives/2003/05/23/my-cheese-sandwich/</code> . </p>
<p> In general for this you must use mod_rewrite, however if you put a filename at the beginning WordPress will attempt to use that to pass the arguments, example:</p>
<p><code>/index.php/archives/%year%/%monthnum%/%day%/%postname%/</code> </p>
<p>If you use this option you can ignore the mod_rewrite rules. </p>
<form name="form" action="options-permalink.php" method="post">
<p>Use the template tags above to create a virtual site structure:</p>
<p>
<input name="permalink_structure" type="text" style="width: 100%;" value="<?php echo $permalink_structure; ?>" />
</p>
<p>
<input type="submit" name="Submit" value="Update">
</p>
</form>
<?php
if ($permalink_structure) {
?>
<p>Using the permalink structure value you currently have, <code><?php echo $permalink_structure; ?></code>, these are the mod_rewrite rules you should have in your <code>.htaccess</code> file.</p>
<?php
$site_root = str_replace('http://', '', trim(get_settings('siteurl')));
$site_root = preg_replace('|([^/]*)(.*)|i', '$2', $site_root);
if ('/' != substr($site_root, -1)) $site_root = $site_root . '/';
?>
<form action"">
<p>
<textarea rows="5" style="width: 100%;">RewriteEngine On
RewriteBase <?php echo $site_root; ?>
<?php
$rewrite = rewrite_rules('', $permalink_structure);
foreach ($rewrite as $match => $query) {
echo 'RewriteRule ^' . $match . ' ' . $site_root . $query . " [QSA]\n";
}
?>
</textarea>
</p>
<p>If your <code>.htaccess</code> file is writable by WordPress, you can <a href="templates.php?file=.htaccess">edit it through your template interface</a>.</p>
</form>

You are not currently using customized permalinks. No special mod_rewrite
rules are needed.
