Re: [PHP] Switch Statement
Hello,
I suggest you put default in that switch statement and var_dump the
$_POST.That should be enough for a programmer to pin point what goes wrong.

Re: [PHP] Switch Statement
Ethan, can you do a var_dump instead of print_r. It might be that next_step
has spaces in it causing the switch to not match.

Re: [PHP] Switch statement Question
Hi,
I have a code snippet here as in the following:
//Switch statements between the four options
switch($string) {
case :
$string= NOT book.author='All';
break;
default:
$string= $string . AND NOT book.author='All';
break;
}
This code does work, but I am wondering if it is possible in the switch statement clauses for me to do something like case does not equal to a certain author name if I don't want $string with that content to be processed. or, do I always use default in this case?
Thanks in advance.

Well I will have to mention that switch becomes if after all internally
so you could always use the if statement.
I am a great fan of switch but since eclipse fail to format correctly
embedded switch statements I am starting to use the old all good if()
since it is the same thing. It is a matter of style actually although
switch is slightly slower (so slightly that you can't notice in any case).
I think there was a thread in this list for this comparison a few days ago.

It's a bit non-conventional, but the switch block can be used like so:
switch(true) {
case (x y):
dosomething();
break;
case (y == 0):
dosomethingelse();
break;
default:
somethingelseentirely();
break;
}
...this way, your case statements can be expressions themselves, and it
will always pick at least one of them to fire.

some people really don't like this kind of thing (hi Robbert :-)),
either way beware that the equality test is not strict, that is
to say autocasting occurs (variable type doesn't have to match)
an example:
switch (true) {
case 1:
echo did you expect this?\n; // -- this is output
break;
case true:
echo or this?\n;
break;
}

No. You can either echo/print with a heredoc (which is still
echoing/printing, but is a lot easier) or you can exit PHP. For example:
?php
switch($somevar){
case 'case1':
print END
some html
some html
some html
END;
break;
case 'case2':
print END
some html
some html
some html
END;
break;
}
?
Or:
?php
switch($somevar){
case 'case1':
?
some html
some html
some html
?php
break;
case 'case2':
?
some html
some html
some html
?php
break;
}

Re: [PHP] Switch statement || How to output html without using echo() or print()
That does the trick, although I'm not exactly sure why.
Shouldn't the html between the ?php case 1: ? and ?php break; }: ?
statements be executed regardless of whether or not case 1 matches the
switch variable?
In Cold Fusion anything outside of cfoutputcf code here/cfoutput is
ignored by the CF language processor; thus the ?php case 1? html here
?php break; }? would display the html for each case.
In any case thanks for workaround -- I would have echoed out all the html
otherwise..

Yes Virginia, there is a PHP function :^]. You can explode your $string_var

Alternatively Alexander,
take a look at the string functions eg strstr(), stristr(), and strpos() all

So you want to share the array across *requests*
That doesn't have *anything* to do with global.
Have a look at how HTTP works - each request is an isolated execution of
a PHP script. it doesn't have any idea of what other pages the user
already looked at. To archieve your stuff you need session management
(phpbuilder.com has a nice tutorial on this)

To archieve your stuff you need session management (phpbuilder.com has a nice tutorial on this) Indeed, this is something I only came to know yesterday when Henrik replied with an answer along the same line: every new instance of the script is isolated from earlier instances, and therefore does not recognize the array. I was confused though, because I thought it could be done as I succesfully transferred other variables. Turned out all those variables were transported inside a FORM, which does get recognized across multiple instances of the script. I'll have a look at documents on session management, thanks for the advice! -- Imar de Vries - [EMAIL PROTECTED] - ICQ 6972439 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
[PHP] switch-statement overrides use of global arrays?
Hi all,
a very frustrating problem. For some reason I am not able to pass on an
array between two functions, although I declare it global in both of
them. I suspect my use of a switch statement to control the flow of the
functions is causing some trouble, but I'm not sure. Changing the order
in which I declare the array global did not help, nor the use of
$GLOBALS.
This is a simple representation of what I do:
switch ($action) {
default:
main();
break;
case test_one:
test_one();
break;
}
// ---
function main() {
$array_test = array();
global $array_test;
$array_test[0] = First array, first element;
$array_test[1] = First array, second element;
print(Content of first array in the main function is now:br);
var_dump($array_test);
print (pform method=\post\ action=\arraytest.php\
enctype=\multipart/form-data\);
?
input type=hidden name=action value=test_one
input type=submit value=Test tabindex=6
/form
?
}
// ---
function test_one() {
global $array_test;
// This results in NULL
print(Content of first array in the first test function is now:br);
var_dump($array_test);
$array_test[2] = First array, third element;
$array_test[3] = First array, fourth element;
// This results in the third and fourth element being shown
print(pAfter addition, content of first array is:br);
var_dump($array_test);
}

Re: [PHP] switch-statement overrides use of global arrays?
Hey-
I would think you would need to define $array_test outside in a global
environment rather then inside the function since I think/thought it will
just stay scoped in there and that global was used to access variables
which weren't defined inside a functions scope and make it look outside.
In other words
//Define GLOBAL
$array_test = array();
switch(){
BLAH
BLAH
}
function main() {
global $array_test;
BLAH
BLAH
}
function test_one(){
global $array_test;
BLAH
BLAH
}
Hope that helps.
Henrik

Yes, the only way I could avoid errors that occurred when I tried to manipulate
the array, was to add a $array_test = array(); a few lines before the switch
statement. Alas, this also emptied the array each time I went from one function
to another via the switch statement.
I guess I am trying something that is just not possible (when I insist on using
the switch statement)?

Re: [PHP] switch-statement overrides use of global arrays?
Well, the switch statement will only run ONE of the functions, never both. The default runs and then you break out of the switch, also: shouldn't default be at the bottom of the switch? or is that just convention? Anyways, there is no way for main() to ever pass anything to test_one(), since only one or the other is called in the switch (unless your switch is in a loop and $action changes in that loop). Oh, your passing it back in via a form and then telling it to use: test_one. Oh, ummm, everytime you submit the code you are calling a new instance of the script. It will never remember variables between instances unless they are passed to the script via POST and hidden fields. At least as far as I know...but I might be missing something. I would try and do whatever you are trying to do without resorting to a resubmit or just pass the variable to the function inside main: test_one($array_global); Sorry I couldn't be of more help.

Re: [PHP] switch-statement overrides use of global arrays?
Imar,
The global array is being defined in the mainline, but not populated. What happens if
you set element 0 to some
value (to take up some storage space first) and then try the switched function calls?
When you say Alas, this also emptied the array each time I went from one function to
another via the switch
statement. do you mean that the array definition line is inside the same loop that
causes the switch statement
to be revisited?
(it shouldn't be - put it right at the beginning of the 'mainline' and ensure that it
is not re-executed (which
would indeed 'reset' the values))
Regards,
=dn

Dl Neil wrote: The global array is being defined in the mainline, but not populated. What happens if you set element 0 to some value (to take up some storage space first) and then try the switched function calls? This did not produce the desired result, unfortunately. The array is filled correctly within the first function, but is empty after we've passed the switch statement en route to the second function. When you say Alas, this also emptied the array each time I went from one function to another via the switch statement. do you mean that the array definition line is inside the same loop that causes the switch statement to be revisited? (it shouldn't be - put it right at the beginning of the 'mainline' and ensure that it is not re-executed (which would indeed 'reset' the values)) The array definition line was not inside the same loop as the switch, which it looked like of course because there was a reset at some point, it seemed. Henriks answer at 23:17 seems to have hit the nail in the head: each time the variable $action is changed (using a FORM), this causes the switch statement to run another function, but this also creates a new instance of the script, in which the variables from the older instance are not known. I'm now working on a solution that uses the same form to pass on some data I need. A bit complex maybe, but I'll leave the code cleaning for version 2.0 of my software :) -- Imar de Vries - [EMAIL PROTECTED] - ICQ 6972439 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

OK. Suppose the possible values for $submit are 'insert' and 'update'. [I
assume those are values _you_ can assign to a submit button]
Then
switch($submit) {
case 'insert':
// Your insert stuff here
break; //So it doesn't fall through to the next case
case 'update:
// Your update stuff here
break;
case default:
// The page has somehow been called without a value (or an
// inappropriate value) for submit
// Error handling or whatever here
}
Does that make it clearer? or muddier :-)
