Hey everyone,

I'm just wondering how the read more feature is achieved in PHP. It is like facebook where it displays a couple of lines then if you're interested in reading more about the status or article click 'read more link' which expands the box.

There are two options (Javasccript, not really PHP).

  1. Simplest: the full text is already in a div, but hidden, and clicking the link will just display that div.

  2. Clicking the link does an AJAX call to a server side script to get the full article, and replaces what's already there.

Is that an easy job? I mean a function or two in jquery becuase I'm designing the app for smart devices.

I get the second step. For the first one though, how could you determine the number of lines to display? is there an example you can refer me to?

Here is an example of a "Read More/Less" feature using jQuery.

<p id="mytext" style="width:260px;height:200px;overflow:hidden;">

<a href="#" id="readml">Read More</a>

<script type="text/javascript">
    $(document).ready(function () {
        var less = 200;
        var h = $('#mytext')[0].scrollHeight;
        $("#readml").toggle(function () {
            $('#mytext').animate({ height: h }, "slow");
            $(this).text("Read less");
        }, function () {
            $('#mytext').animate({ height: less }, "slow");
            $(this).text("
