<p>This plugin allows you to place a shortcode in a post that passes encrypted logon information to Moodle, using the <a href="https://github.com/ppv1979/woo2moodle-moodle">Woo2Moodle authentication plugin</a> for Moodle 2.2+. The user will be created (if required) by Moodle and optionally enrolled in the specified Cohort(s), Course(s) and/or Group(s).</p>
<p>Use the Moodle button on the rich editor to insert the shortcode, or enter the details manually using the examples below as a guide.</p>
<p>Example: <code>[woo2moodle class='css-classname' group='group1' cohort='class1' target='_blank' authtext='Please log on']launch the course[/woo2moodle]</code>.</p>
<table class="woo2m-table">
    <thead><tr><th>Attribute</th><th>Purpose</th><th>Example</th></tr></thead>
    <tbody>
    <tr><td><code>class</code></td><td> optional, defaults to 'woo2moodle'; CSS class attribute of link</td></tr>
    <tr><td><code>cohort</code></td><td> optional, idnumber of the cohort in which to enrol a user at the moodle end. You can specify multiple values using comma seperated strings.</td><td><code>[woo2moodle cohort='business_cert3']enrol in Cert 3 Business[/woo2moodle]</code></td></tr>
    <tr><td><code>group</code></td><td> optional, idnumber of the group in which to enrol a user at the moodle end (typically you use group <i>or</i> cohort). You can specify multiple values using comma seperated strings.</td><td><code>[woo2moodle group='eng14_a,math14_b,hist13_c']Math, English & History[/woo2moodle]</code></td></tr>
    <tr><td><code>course</code></td><td> optional, idnumber of the course in which to enrol a user at the moodle end. You can use multiple ids</td><td>(as above)</td></tr>
    <tr><td><code>target</code></td><td> optional, defaults to '_self'; href target attribute of link</td><td><code>target="_blank"</code></td></tr>
    <tr><td><code>authtext</code></td><td> optional, defaults to content between shortcode tags; string to display if not yet logged on</td></tr>
    <tr><td><code>activity</code></td><td> optional, numerical index of the first activity to open (> 0) if auto-open is enabled in the Moodle plugin</td></tr>
    </tbody>

<p class="description">The <em>idnumber</em> mentioned above is not the same as the course id (which is a number); moodle has a special field called "idnumber" which is an alphanumeric value. If you mix them up, it won't work!</p>
<p class="description">The link that is generated is timestamped and will expire, so it cannot be bookmarked or hijacked. You must set the expiry time in the Moodle plugin. You should allow reading time of the page when considering a timeout value, since the link is generated when the page is loaded, not when the link is clicked. </p>

<?php if (class_exists('WooCommerce') || class_exists('MarketPress')) { ?>
<h3>MarketPress or WooCommerce?</h3>
<p>Selling with MarketPress or WooCommerce? Create a text file called "yourcourse-woo2moodle.txt" (actually, the name only has to <strong>end with</strong> <code>-woo2moodle.txt</code>; the name before that can be whatever you like) and write ay attributes (shown above) on their own lines into it, like this:</p>
<table class="woo2m-table">
    <tr><td>
        <code>group=maths102_sem2</code><br>
        <code>cohort=2015allCourses</code>
    </td></tr>
</table>
<?php } ?>
<p>Upload this file as your digital download for the product. Then, after a purchase instead of a download, they will redirect to your Moodle site with an authentication token just like a shortcode link. Pretty neat, huh?</p>
