Can I use the same PHP program to call itself?

[ExeByte]

Hi All,
May I write the following code in PHP?

echo '<ol><FORM NAME="HOUR" ACTION="TForm.php" METHOD="GET">'.
                '<input type="submit" name="subDisplay" value="DISPLAY">'.
                '<input type="submit" name="subThumbs" value="SLIDESHOW">'.
                '<input type="text" name="JCC" size="12" readonly value="'.$JCC.' images in ">'.
                '<input type="text" name="idir3" size="40" readonly value="'.$thour.'">'.
                '<input type="submit" name="subDelete" value="DELETE">'.
                '</form></ol>';    

Then can I receive this code in the same program with the following code

if (isset($_GET['subDisplay'])){        
    if(isset($_GET['idir3']));{
        $dirname=$_GET['idir3'];
        showimages($dirname);}}if (isset($_GET['subThumbs'])){    
    $ss = $_GET['idir3'];
    if($ss=='../KamImgs') {exit("Not authorized");};
    if(! is_dir($ss)) {exit("Not a valid directory");} ;if (isset($_GET['NEXT'])){print_r2 ("5NEXT");
    $timg=$_GET['$_SESSION'];
    $JCOUNT=$_GET['jcount'];$JCOUNT++;print_r2("5JCOUNT = $JCOUNT");
    $JTOT=$_GET['jtot'];print_r2("5jtot = $JTOT");

Why are you do this?
You wanna generate a html form?

Maybe you can try this:

<FORM NAME="HOUR" ACTION="TForm.php" METHOD="post">
<input type="submit" name="subDisplay" value="DISPLAY">
<input type="submit" name="subThumbs" value="SLIDESHOW">
<input type="text" name="JCC" size="12" readonly value="<?php echo $JCC; ?> images in ">
<input type="text" name="idir3" size="40" readonly value="<?php echo $thour; ?>">
<input type="submit" name="subDelete" value="DELETE" />
</form>
 

php code inside html code,
Hope to useful
