POST BACK in PHP or JAVASCRIPT?
<p>how can I post back the data that are already in the text field?</p>

<p>example: 
if I miss one of the required field an error will prompt when i click the submit button.</p>

<p>How can I make an post back data in that form using php or javascript and make the cursor of the mouse directly located to the field that caused an error?</p>
