Confusing POST behavior -- doing it twice?

(posted previously on comp.lang.php but no response received. Cross-posted
in the dreamweaver forum)

I am confused about what goes on with method POST. Here is an overview of a
my code, sketching it out:

<?php
if (isset($_POST['Submit']) && $_POST['Submit']=="Submit") {
---Do a bunch of stuff---
if (isset($_SESSION['Error'])) unset($_SESSION['Error']);
if (strcmp($A, "any") {
// Verify that a Zip code is numeric and is five digits
If (!is_numeric($_POST($zip)) strlen($_POST($zip)) != 5) then {
$_SESSION['Error'] = "an error description";
header("Location: thisSite.php:);
}
}
}
header("Location: anotherSite.php:);
?>

...... in the form description I have an
<?php if (isset(($_SESSION['Error'])) echo $_SESSION['Error']; ?>
(Note: The form is type POST).

So here is the problem:
1 - When I start, there is no error message.
2 - I deliberately put in a bad zip code and have a value other than "any"
in the A control and click to submit it.
3 - Instead of going back to thisSite.php and displaying the error message,
it goes to anotherSite.php.
4 - If I then hit the back arrow on the browser, it displays with the error
message on thisSite.php

It seems that
1 - on the submit it goes through the logic and sets the error.
2 - It then must be going through a second time, but this time taking on the
default setting of "any" for control A and so bypass the logic on the zip
code and so goes to anotherSite.php.

Please help me here.

Hi Shelly,

Please include an else:

// Verify that a Zip code is numeric and is five digits

if (!is_numeric($_POST($zip)) strlen($_POST($zip)) != 5) then {
$_SESSION['Error'] = "an error description";
header("Location: thisSite.php");
}else {
header("Location: anotherSite.php");
}

Let me know how you do.

Cheers,

Hi,

Shouldn't this be:
$_POST["zip"] instead of $_POST[$zip] ??

Are you expecting a posted name/value with 'zip' as name?

$_POST[$zip] will try to fetch WHATEVER $zip will be, probably nothing.

Yes, it is 'zip' and, yes, there is a "zip" control. I just typed wrong in
entering it here. I corrected it above and further corrected my typing of
this post to "[" instead of "(".

Here is the corrected post. I made about 5 errors in typing this post the
first time that are not in the actual (full) code.

I am confused about what goes on with method POST. Here is an overview of a

<?php

// Verify that a Zip code is numeric and is five digits
If (!is_numeric($_POST['zip']) || strlen($_POST['zip']) != 5) then
{
$_SESSION['Error'] = "an error description";
header("Location: thisSite.php");
}

header("Location: anotherSite.php");

There are several things that I am not crazy about in your code. And your
usenet post

0) looks like you have MULTI-posted, not CROSS-posted. There is an
important distinction.

1) you may want to consider using "and" instead of "&&". See:
http://www.php.net/manual/en/languag...ors.precedence
(minor issue)

2) Why use strcmp() when == will do? In any case, according to your step
number (2) what you do will not trigger true in "if (strcmp($A, "any") {"
so it will just skip all that stuff and drop out to the final Location
header -- anotherSite.php

3) "When I start, there is no error message" -- when you start what? You
mean, "$_SESSION['Error'] is unset before any of this stuff happens? What
is the error message that appears when you "If I then hit the back arrow
on the browser, it displays with the error"?

4) Your syntax is goofy on a couple of the if() statements.

if (isset($_SESSION['Error'])) unset($_SESSION['Error']);

Why is that whole thing in parens? Is the last paren just before the
semicolon a typo?

If (!is_numeric($_POST($zip)) strlen($_POST($zip)) != 5) then {

How about this one? It *looks* like it has a typo. I can't tell. It looks
like it is missing an "and" or "or" (or && or ||). Are you cutting and
pasting *actual* code into your Usenet post or is this hand typed?

5) The $_SESSION stuff will only show up on sites within the same base
URL. Are "thisSite.php" and "anotherSite.php" on the same server?

6) You are supposed to use absolute URLs when doing a
"header('Location:...')" redirection. Most browsers and servers and PHP
itself are flexible in this regard, but the "official" requirement is the
full URI including "http://".

7) You really should also include "exit;" as the very next line after any
header("Location:..."); -- unexpected results occur otherwise (I learned
the hard way).

8) A cleaner and simpler way (for me) to match five numeric digits is with
regular expressions -- e.g. preg_match(). With PHP's loose data typing, a
numeric thing might actually be a string. In any case, here is how:

preg_match("/\d\d\d\d\d/", $zip);

or

preg_match("/\d{5}/", $zip);

9) One last thing: It would be helpful to see your HTML form as well.

it in another forum.

1) you may want to consider using "and" instead of "&&". See:
http://www.php.net/manual/en/languag...ors.precedence

I'll look at it. I am so used to C and Java coding (new to the web coding
and PHP) that I used the ones I knew.

2) Why use strcmp() when == will do? In any case, according to your step
Force of habit (and it would be !=, not ==).. I use strcmp because of past
programming experience. To compare strings you use strcmp (or an
equivalent). An "==" compares the addresses of the two items and not the
values of the two items, since strings are arrays in these other languages.
number (2) what you do will not trigger true in "if (strcmp($A, "any") {"
so it will just skip all that stuff and drop out to the final Location
header -- anotherSite.php
The strcmp is correct. If $A is NOT equal to "any", then strcmp returns
other than zero and the code IS perfermed. That is what I want to happen.
3) "When I start, there is no error message" -- when you start what? You
mean, "$_SESSION['Error'] is unset before any of this stuff happens? What
Yes.
is the error message that appears when you "If I then hit the back arrow
on the browser, it displays with the error"?
The value that I set it to when the condition of a bad zip code is met.
4) Your syntax is goofy on a couple of the if() statements.

if (isset($_SESSION['Error'])) unset($_SESSION['Error']);

Why is that whole thing in parens? Is the last paren just before the
semicolon a typo?
It isn't all in parens, and it isn't a typo. Look again. The first left
paren opens the if. The second left paren opens the isset. These are both
closed before the unset. The next left paren opens the unset and the right
paren before the semicolon closes it. The syntax is correct.

If (!is_numeric($_POST($zip)) strlen($_POST($zip)) != 5) then {

How about this one? It *looks* like it has a typo. I can't tell. It looks
It is a type (along with MANY others that typed in wrong -- but are correct
in the code). I submitted corrected code in a later post.
like it is missing an "and" or "or" (or && or ||). Are you cutting and
pasting *actual* code into your Usenet post or is this hand typed?
By hand -- BIG mistake on my part. I won't do that again.
5) The $_SESSION stuff will only show up on sites within the same base
URL. Are "thisSite.php" and "anotherSite.php" on the same server?
Yes.
6) You are supposed to use absolute URLs when doing a
"header('Location:...')" redirection. Most browsers and servers and PHP
itself are flexible in this regard, but the "official" requirement is the
full URI including "http://".
Mine works with relative URLs.
7) You really should also include "exit;" as the very next line after any
header("Location:..."); -- unexpected results occur otherwise (I learned
the hard way).
That is how I actually just solved this problem. I was about to post that
message (that I solved my problem) when I read your post first. It works
now, but I don't understand why.

8) A cleaner and simpler way (for me) to match five numeric digits is with
regular expressions -- e.g. preg_match(). With PHP's loose data typing, a
numeric thing might actually be a string. In any case, here is how:

preg_match("/\d\d\d\d\d/", $zip);

or

preg_match("/\d{5}/", $zip);
Thanks. I'll implement that. However, I don't think I care here whether it
is a string or a number. Actually EVERY input from the screen as user input
is a string. I know that in Java you must convert all of these to numbers
with the appropriate parse_ method. Is there a pressing reason not to do it
the way I did?
9) One last thing: It would be helpful to see your HTML form as well.


I realize that now. I should have said that A is a control that is a list
box. One of the values is "any". I amd doing a distance match and if the
choice is "any" I don't care what the user's zip code is. I only care when
a distance is specified in the list box. (that is why the strcmp logic). I
also should have said that "zip" is the control for the zip code.

Thank you for your time and suggestions.

Just a remark: Why do you not always unset the error?
Or is this code in a more complex environment where you want to be able too
keep the custum-errormessage around?
(Not important, just curious)

if (strcmp($A, "any")) {
// Verify that a Zip code is numeric and is five digits
If (!is_numeric($_POST['zip']) || strlen($_POST['zip']) != 5) then
{
$_SESSION['Error'] = "an error description";
header("Location: thisSite.php");
Add
exit 0;

The header you set will just do that: set the header.
The program will run on from there.
Later on you will be able to give it another value (which you actually do).
So you have to force PHP to quit here.

}
}
}
header("Location: anotherSite.php");
Here you overwrite your previously set header. :-/

?>

..... in the form description I have an
<?php if (isset(($_SESSION['Error'])) echo $_SESSION['Error']; ?>

(Note: The form is type POST).

So here is the problem:
1 - When I start, there is no error message.
good.
2 - I deliberately put in a bad zip code and have a value other than "any"
in the A control and click to submit it.
Ok, and your code catches that just fine. :-)
3 - Instead of going back to thisSite.php and displaying the error
message, it goes to anotherSite.php.
Yes. Because you forgot the exit command.
4 - If I then hit the back arrow on the browser, it displays with the
error message on thisSite.php
Well...
The infamous BACK-button.
I hate that thing.

I have really nothing constructive to tell you on this point.

As far as my experience goes: It is implemented differently on different
browsers.
I have seen the following things (over many years):
Some just fetch the HTML from cache and display that.
Or maybe some even repost (if a form was used to produce the HTML) without
your knowledge.
Others warn you you are viewing possibly out-of-date html.
Or they warn you that you are reposting the form.

Of course you can modify their behavious with extra option in headers
concerning cache-control, document-expires, etc. etc.

Everything is possible and it gives me a headache.

I have no idea how the current mostly used browser behave.
Maybe things improved and they all do the same, but I doubt it.


It seems that
1 - on the submit it goes through the logic and sets the error.
Yes.
2 - It then must be going through a second time, but this time taking on
the default setting of "any" for control A and so bypass the logic on the

Because of the missing exit, but I told you that already. :-)

I hope I did.

Not really, no. With cross-posting, two useful things happen. Replies

No! They are significantly different from each other. Multi-posting
creates independent threads that cannot be (easily) tracked together;
cross-posting creates a cohesive thread spread across multiple groups.
If you keep multi-posting, you will hear other complaints. You have been
warned.

slightest chance of not being read correctly.
Sounds good. Personally, I hate even the shortcut of (for example):

if (1) do thing;

No curlies!

I much prefer
if (1){
do thing;
}

Even for one-line things.
<snip snip!> Is that 3 equals signs?


Yes.

You're welcome. I dated a Shelly once. Spelled "Shelley" though. I
think.


You wouldn't like my type :-). It is a gender thing. Besides, my wife of
42 years might object :-). The name on my birth certificate is Sheldon.

Shelly


Well, I *could* be gay.
