You need to specify the type of the element (type="text").

I did just that.. school_type_oth er is type="text", which in HTML is
never a requirement, in fact, before I tried that none of the other
HTML form element text field tags have type="text" and work just fine.
I added type="text", still no $_POST['school_type_ot her'] even though I
entered it!

Can you post the element after the values are parsed in it by PHP?

Just curious... why are you doing this when

if ($_POST['hasReviewedApp licant']) echo $_POST['school_type_ot her'];
else echo
htmlentities(st ripslashes($res ult[0]->school_type_ot her),ENT_QUOTES );

Does the same thing,

Please post the code for the whole form.

Also, when you first enter the processing script, what does:
<?php echo '<pre>' . print_r($_POST, true) . '</pre>'; ?>
display on the screen?

Even if I were allowed to do so - which I'm not as it is fed gov't
property and even posting code is considered a federal no-no, it's over
3,000 lines long, sorry :(

And if it gets weirder I can't duplicate the error, even after several
tries, $_POST['school_type_ot her'] now exists.

newbie question: can't make newline character work in echo

learning php here - I'm echoing some debug code, and I cannot seem to make
the newline character work.

For example, I tried this:

echo "supposedly , this will \nbe on \nmultiple lines.";

which, according to the php manual, should produce this:

supposedly, this will
be on
multiple lines.

But it doesn't work! It's all on the same line. What obvious thing am I
missing?

newbie question: what is simple way to open a new url from php?

Sorry for this really basic question, but assuming you have created a URL
string in your code, how do you cause a window to be opened with that url?

I've been searching the manual, but haven't found it yet.

I've seen reference to CURL libraries, but that seems a bit complicated for
the simple thing I'm trying at the moment. Thanks!

Display your html source. You'll see the newlines there.

This isn't a PHP problem - it's how HTML works. Newline characters are
ignored. Instead, you need to use <br> to start a new line.
See the nl2br() function.

Thanks - I didn't think of looking at the source instead of the screen
output. Makes total sense. I've got it doing what I want now.

That's not what I meant, sorry.

Maybe I don't have a clue yet, but I wrote a php function that you call from
a button. It takes a bunch of parameters, and assembles them into a URL
string.

Now that I have the URL string (inside my php function), how do I call that
URL and get that page to open up in a window?

I /think/ you'd probably have to use PHP to output some Javascript to do
that.

Thanks for the reply.

I've since discovered curl for at least getting the page to display:

$ch = curl_init();
curl_setopt($ch , CURLOPT_URL, "http://www.eample.com" );
curl_exec ($ch);
