Re: [PHP] Is there a "GoTo Page" Function?
Not without seeing some html code. If you haven't altered any of the other font/color settings I'd have thought they'd all be the same color, black. Look up some info on 'Cascaded Style Sheets',... then it'd be as simple as and all of the text/alignment, etc,.. takes the settings of whatever is defined in "blue". Jim.

Re: [PHP] Is there a "GoTo Page" Function?
Thanks Jim, Now that looks better. New problem: in one of the almost identical tables I've used it in, the title for each row is in black and not the color that the page text is set for. The other table is correctly set. Any idea what would cause the discrepancy?

You can name a function whatever you want -- they're arbitrary,
user-defined puppies. HOWEVER, the contents of a function need to do
what you want -- the function that I showed you creates a very specific
input, named "name" or something like that. So for each other input you
want to create within a function, you'd have to make sure that they
created unique inputs.
Personally, I put all of my inputs into one function, and the function
itself does both the error checking and the form-printing. This is
probably not the cleanest way to do it, but it works -- in this case,
the function is more of a subroutine than a proper function.
(Subroutines and functions are more or less the same thing in PHP,
there's no syntactic difference.)

If you get to a point where you feel comfortable with PHP, you might
consider investigating the Python language. It's got a very different
feel, for instance you don't use bucks to indicate variable names, and
there are braces around function definitions or if statements. Rather,
you use whitespace to keep code chunks organized. Some people believe
this is a more organized way to write code. Python is probably more apt
for writing standalone programs and scripts, whereas PHP is more apt for
writing web applications, but that's an opinion of mine and you can
really use either language for either of those. www.python.org for more
info.

Yes, a formatting/HTML question. I learned everything I needed to know
about HTML from Sams Teach Yourself HTML/XHTML in 24 hours or from the
web itself. That book was also super super easy. I'd say a little bit
too easy if you're already learning things like PHP, which are a more
advanced topic. I am not a very good designer, so I can't really answer
your question directly, but I find that forms lend themselves well to
being placed within HTML's tables.

";
?>
But when you see this in a web page, it is nicely formatted. Don't
forget to customize the way the table looks by declaring borders and
cell spacing in a style sheet.
Also, as an exercise, come up with a clever way to put this code into a
function.

Whack your text and input boxes in different cells of a table,.. use align (or nowadays an appropriate style setting) and that should get your things lined up :-) "Andre Dubuc" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED].; > Hugh, > > Food?

Re: [PHP] Is there a "GoTo Page" Function?
Andre,
Yes, the html page with your input form effectively ends with the
tag so any decision statements on that page past that tag would miss the
form input. So, put any decision statements on the php page where you've
put your database code. I'm sure someone will educate me on the above
statements, and I'll likely deserve it. When you eventually use the
$php_self call, you can put everything on one page above the form start.
You can have as many calls on an html page as is needed to complete
your tasks. However, I use php to do some rather complex math (it's complex
to me at least), so I got in the habit of using php throughout a page
without breaking out for html. For me it is more readable.
My $00.02 on books, I bought a Sams 24 hour book on php for $25, and it got
me off the ground. The online manuals for php and mysql have also been
invaluable. Save your money, buy food instead.
Hope this helps,
Hugh

Re: [PHP] Is there a "GoTo Page" Function?
Andre,
My note on decision lines was in anticipation of your next question/problem
of "How do I handle things if the user doesn't fill in his name, address,
whatever?" My solution is check to see if the cell is filled and if not
then quit the database storage and tell the person to fill in the info. I
first check to see if the data is set and if not, send a message. This
would come before wasting your time storing anything. There are many other
methods to check user input but I learned the if (!isset($something)) die()
method first, and to me it's the most straight forward.
Hope this helps,
Hugh

Hi Erik,
And thanks again!
I like the 'function print_name_form()' -- I gather you could do this for all
the NOT NULL variables that a form requires. Further, would you just change
the "print_name" to 'print_whatever-other-variable' that I would want to
check? Is there another way to consolidate the code at this point? Or would I
just duplicate the code for each not-null variable?
[Btw, I sometimes long for the old Paradox PAL code that seemed so difficult
at the time I learnt it -- PHP is very similar, but the syntax seems so much
more compact.]
While we're on the topic of fields ('input type=text") is there anyway to
include a non-printing space in the data entry, say for 'Name", that would
not be passed to the database? Thus, on the screen it would appear:
Name: [non-printing space]Andre but in the database entry: Name:Andre
This isn't a pressing question, and probably is a formatting question, but I
wonder if it's possible?
Tia,
Andre

Yep, the submit input tells the form "go do your thing", but the form
already knew where to go (because you specify where to go in the
'action' attribute). The form also knows how to go -- whether it should
be POST or GET. Without realizing it, you'll be learning more about the
HTTP protocol itself as you start writing scripts that take advantage of
its features.

Firstly, your browser is what determines how the form is sent -- but
usually, it's normal for the Enter key to act as the "Submit" button (a
nice keyboard shortcut that I take advantage myself). It should not act
in this fashion if you are typing into a textarea tag, because you might
want to enter newlines/cr's in the textarea, but for most other form
fields it's normal. If you want to jump from one field to the next with
a key press, use tab.
Secondly, you're wondering where to check for the presence of the data?
How about this:
";
}
if (!$_POST['name']) {
print "You need to fill in your name.";
print_name_form();
} else {
print "Thank you!";
}
?>
Why did I define a function in the beginning? Well, this way, if the
user didn't enter a name, they don't have to hit "back" in their
browser. The form just appears again. This is much more useful if you
have this same function accessible from each page/script you are
writing, so that you don't have to waste your time. Later, when you
learn how to check for errors in your user's input (such as if the user
entered a bunch of numbers instead of a name), this will come in handy
so that you can save the user's legitimate values but ask them to
re-enter their invalid values. That gets kind of technical, but it's
one of the sweet things about functions, that they are reuseable.

When the "submit" button is hit, the form executes the script located at the URL specified in the "action" attribute of the tag. So do this: $script_target = "./nameofscript.php"; print ". "; in your PHP. If you're new to this, don't worry about using PHP_SELF to call the same script, just make a new page with the code that handles the first page's data. But eventually you'll probably want to clean up your style and use switch() statements or if statements to keep it all in one page.
