One of the biggest wants with MT is to password protect individual entries. There are several hacks and bits of code that allow you to password protect entries but many of them are long winded and many involve separate categories. I wanted a simple way to selectively password protect entries no matter what the category, what blog etc.
So I created a new field on the entry screen (click screenshot for a larger view) that would contain the password. For this to work you will need to be using MT 3.1x, mySQL and PHP. To see this in action see the front page on my blog, enter the password "password" and you will be granted access for 10 days.
And yes I'm perfectly aware WordPress has this functionality built in!
]]> First off all run this query on your mysql database, all it does is add a new column called entrypassword to your mtentry table.Alter table mt_entry add column entry_password text
Next open up lib/MT/App/CMS.pm and find around line 656
$q->param($col) : $obj->$col();
}
if ($type eq 'entry') {
and add below it
$param{password} = $obj->password;
Save CMS.pm and open lib/MT/Entry.pm and right at the top you'll see the columns in the mt_entry table being defined. Find
'basename',
and replace it with
'basename','password',
Save Entry.pm. This next change we're going to make will create a new <MTEntryPassword> tag. Open up lib/MT/Template/Context.pm and search for
$ctx->register_handler(EntryMore => \&_hdlr_entry_more);
and add immediately underneath it
$ctx->register_handler(EntryPassword => \&_hdlr_entry_password);
Next find
sub _hdlr_entry_title {
and add immediately above it
sub _hdlr_entry_password {
my $e = $_[0]->stash('entry')
or return $_[0]->_no_entry_error('MTEntryPassword');
my $password = defined $e->password ? $e->password: '';
$password;
}
Save Context.pm and open edit_entry.tmpl, find
<TMPL_VAR NAME=CREATED_ON_FORMATTED ESCAPE=HTML>
</TMPL_IF>
and add underneath it
<br />
<label><MT_TRANS phrase="Entry Password"></label><br />
<input name="password" id="password" value="<TMPL_VAR NAME=PASSWORD>" />
Save edit_entry.tmpl and upload these files. Next you'll need to create a new static index template called mt-password.php. For the template body, copy the contents of this file. The file sets a cookie that lasts 10 days. To change the length it lasts, change 864000 to another time frame in seconds, for example a day would be 86400 etc.
Save and rebuild the template.
This next bit depends on whether you publish statically or dynamically. I'll walk you through both ways.
Static Publishing
At the top of all templates where you use <MTEntry> tags, add the following
<?php
include('<$MTCGIServerPath$>/php/mt.php');
$mt = new MT(<$MTBlogID$>, '<$MTCGIServerPath$>/mt.cfg');
$db = $mt->db(); ?>
This must be added right at the top, before the DocType declaration.
Next, just before the <MTEntryBody> tag, add this
<?
$pass = $db->get_var("select entry_password from mt_entry where entry_id = <MTEntryID>");
$cookie = 'mt-postpass_'.md5($pass);
if($pass == "" || isset($_REQUEST[$cookie]) ) { ?>
Finally just before the posted section add
<? } else { ?>
<form action="<MTBlogURL>mt-password.php" method="post">
<input name="entry_id" value="<MTEntryID>" type="hidden" />
<p>This post is password protected. To view it please enter your password below:</p>
<p><label>Password:</label> <input name="post_password" type="text" size="20" />
<input type="submit" name="Submit" value="Submit" /></p>
</form>
<? } ?>
For the RSS templates, you'll need to do something slightly different. Wherever you find an <MTEntryBody> tag, replace it with
<MTIfEqual a="[MTEntryPassword]" b=""><$MTEntryBody encode_xml="1"$></MTIfEqual><MTIfNotEqual a="[MTEntryPassword]" b="">This post is password protected.</MTIfNotEqual>
To make this work, you'll need to install the Compare plugin
Rebuild all the files. To password protect an entry, type in a password into the Entry Password field on the edit/new entry page and once the pages are rebuilt, readers will need to enter a password to be able to gain access to the entry.
Dynamic publishing
With dynamic publishing, things are slightly easier since we're already in a PHP environment. In all templates that call <MTEntry> tags, add this right above the <MTEntryBody> tag
<?php
$entry = $this->stash('entry');
$pass = $entry['entry_password'];
$cookie = 'mt-postpass_'.md5($pass);
if($pass == "" || isset($_REQUEST[$cookie]) ) { ?>
and add this right above the posted section
<?php } else { ?>
<form action="<MTBlogURL>test.php" method="post">
<input name="entry_id" value="<MTEntryID>" type="hidden" />
<p>This post is password protected. To view it please enter your password below:</p>
<p><label>Password:</label><input name="post_password" type="text" size="20" />
<input type="submit" name="Submit" value="Submit" /></p>
</form>
<?php } ?>
The RSS templates are slightly different. Replace the <MTEntryBody> tag with
<?php
$entry = $this->stash('entry');
$pass = $entry['entry_password'];
if($pass == "") { ?><$MTEntryBody encode_xml="1"$>
<?php } else { ?>
This post is password protected.
<?php } ?>
And now you're done. To password protect an entry, type in a password into the Entry Password field on the edit/new entry page now, readers will need to enter a password to be able to gain access to the entry.
