(EDITED)
Hello,
In the form below, the filed for <div class="urlfield"><input name="url" type="url" id="url" maxlength="
500"></div> fine when a URL is submitted that has a "http://" at the beginning of it.
However, it doesn't work if a URL is submitted with only a "www." in front of it, or with neither a "http://" nor a "www."
How can I make it work in all if the submitted URL has any or none of the following at the beginning of it:
http://
www.
http://www.
Thanks in advance,
John
