A quick and easy shortcode to embed iframe’s that resize to the content of the remote site.
Auto iFrame shortcode is in the format of:
<pre><code>[auto-iframe link=xxx tag=xxx width=xxx height=xxx autosize=yes/no]
</code></pre>
Where:
<ul>
<li>link = the url of the source for the iFrame. REQUIRED.</li>
<li>tag = a unique identifier in case you want more than one iFrame on a page. Default = auto-iframe.</li>
<li>width = width of the iFrame (100% by default). Can be % or px. Default = 100%.</li>
<li>height = the initial height of the iframe (100% by default). Can be % or px. Default = 100%.</li>
<li>autosize = enable the auto sizing of the iFrame based on the content. The initial height of the iFrame will be set to “height” and then resized. Default = true.</li>
<li>fudge = a fudge factor to apply when changing the height (integer number, no “px”). Default = 50.</li>
<li>border = enable the border on the iFrame. Default = 0.</li>
<li>scroll = enable the scroll bar on the iFrame. Default = no.</li>
<li>query = pass the parent’s page query string to the iFrame. Default = no.</li>
</ul>
Note: Auto re-sizing of the iFrame for cross domain sites does not work, this is a security protection provided by the browser and there is no way around it.
Now supports (Shortcode UI)[https://github.com/fusioneng/Shortcake] (aka Shortcake)!
