    Hold the form values in an array with blank values. Then if the page has been posted load those values into the placeholders in the array.

    PHP Code:
    $frm_vals = array(
        
    'name'=>'',
        
    'addy'=>'',
        
    'phone'=>''
    );

    if(
    $_POST){
        foreach(
    $frm_vals as $key=>$val){
          
    $frm_vals[$key] = $_POST[$key];
        }

    Now you have form values for the inputs...if the page has been posted then the values will be filled, or else they will be blank...you inputs would look like

    PHP Code:
    echo "<input name=\"name\" value=\"".$frm_vals['name']."\">"
    if using ajax you could do the same thing by returning the array values as JSON instead of hard-coding the form with PHP.
