This tool will scan links with the specified domains for the query string variables listed below and ensure that they are updated with the appropriate values. These valued can be defined by:
<ol>
<li>Post/Page settings</li>
<li>URL</li>
<li>Client Side Cookie</li>
<li>Server Session Cache</li>
<li>Defaults (in the global admin)</li>
</ol>
The list above indicates the order of override – in short, settings for a post/page will cause mismatching values set via url to be ignored. Note: This processing will only apply to material output via the_content() (this includes pages & posts).
For example – if the domain is www.wordpress.org and the query string variables defined are “affiliateID” and “trafficSource”, any links to www.wordpress.org would have the affiliateID & trafficSource query string variables appended. If they are already in the link’s url, it will update those variables to the correct values.
<h3>Requirements</h3>

This plugin requires <a href="https://www.appthemes.com/themes/classipress/?aid=26553" rel="nofollow ugc">Classipress</a> theme to be installed.
If you are an owner of a <a href="https://www.appthemes.com/themes/classipress/?aid=26553" rel="nofollow ugc">Classipress</a> site, then you might have created a custom field for storing and displaying seller’s phone number. But this field is no special field, it just shows information like any other.
After you install this plugin, field with a phone number will become a link you can click on and if you are using your phone you will be able to dial the number directly.
You can even add an icon on the left or right side of the number. There are 12 icons to choose from, and you can add your own if you like. Just copy them to plugin images folder.
