I have a simple form that echos a value on submit using form. I want this value to be written to a text file, I cant seem to figure out why my code is not working any ideas?
<?php
if (isset($_POST['button1'])) {
$txt=$_POST['button1'];
file_put_contents('status.txt',$txt,FILE_APPEND|LOCK_EX);
exit();
}
?>
<form method="post" action="<?php echo $PHP_SELF;?>">
Restaurant Open:
<input type="radio" name="button1" value="Open" onClick="submit();" <?php echo ($_POST['button1'] == 'Open') ? 'checked="checked"' : ''; ?> /> Open
<input type="radio" name="button1" value="Closed" onClick="submit();" <?php echo ($_POST['button1'] == 'Closed') ? 'checked="checked"' : ''; ?>/> Closed
</form>
<?php
if (isset($_POST['button1']) == 'Open')
echo "Open Today.";
else if (isset($_POST['button1']) == 'Closed')
echo "Closed Today.";
?>

Answer 1

The form disappears because you exit() before writing anything.

Answer 2

I suggest you to use this code.
on the radio button, I changed
<?php echo ($_POST['button1'] == 'Open') ? 'checked="checked"' : ''; ?>
into
if($_POST['button1'] == 'Open') echo "checked=checked"; ?>
which will avoid misunderstood.
<?php
if (!empty($_POST['button1'])) {
$txt=$_POST['button1'];
file_put_contents('status.txt',$txt,FILE_APPEND|LOCK_EX);
//removed exit
}
?>
<form method="post" action="">
Restaurant Open:
<input type="radio" name="button1" value="Open" onClick="submit();" <? if($_POST['button1'] == 'Open') echo "checked=checked"; ?> /> Open
<input type="radio" name="button1" value="Closed" onClick="submit();" <? if($_POST['button1'] == 'Closed') echo "checked=checked"; ?> /> Closed
</form>
<?php
if ($_POST['button1'] == 'Open')
echo "Open Today.";
elseif ($_POST['button1'] == 'Closed')
echo "Closed Today.";
else
echo "Choose a status.";
?>
