Hi Experts,<br />
<br />
I need to validate the value of a text box. &nbsp;The text box is for the customers phone number in the format 0123456789 (ie 10 numbers only)<br />
<br />
The data is sent to a page (validate.php) via a forms POST method.<br />
<br />
I want a function that will ONLY accept 10 numbers one after another, no letters or characters.<br />
<br />
Thanks in advance.
