[PHP] Lost variables
Perhaps. I always use the same phrase to open up an array.
foreach($myarray as $var=$val) { $$var= $val; }
You can also nest it into another foreach statement to extract from an
associative array.

[PHP] Lost Variables
First -- thank you for reading my post.
I am using the general strategy suggested by Jay (thanks, Jay) to process my
form in another procedure. It's listed below. In my processStuff.php
program, I use the following code:
$attributes = array();
$attributes = array_merge($attributes,$HTTP_POST_VARS, $HTTP_GET_VARS);
extract($attributes, EXTR_PREFIX_SAME, this);
I want to load my numerous post variables into regular memory variables (or
whatever the php nomenclature is) -- e.g. $_POST['action'] becomes $action.
It doesn't seem to working according to the manual. I list my
$HTTP_SESSION_VARS, there are none.
I would appreciate anyone taking the time to explain to me how this works.
Either it's stupid or I'm stupid. I'm figuring it's me.
Monique.
form method=post name=form1 action=processStuff.php
input type=submit name=action value=Add Record
input type=submit name=action value=Delete Record
In processStuff.php
?php
switch ($_POST['action']){
case Add Record:
...do stuff...
..redirect back to original page...
break;
case Delete Record:
...do stuff...
..redirect back to original page...
break;
}

Re: [PHP] Lost Variables
To turn $_POST[var1], $_POST[var2], $_POST[var3] into $var1, $var2,
$var3:
if(isset($_POST))
{ foreach($_POST as $key=$value)
{ $$key= $value; print($$key= $value; br /); }}
This should do it. The print statement is just to check the result.

Re: [PHP] Lost Variables
Thank you, Alberto. Do you know -- does the extract() function not work?

How is it not working? What does var_dump($attributes) show?
I list my $HTTP_SESSION_VARS, there are none.
Is this related to the above? $HTTP_SESSION_VARS would normally be empty
unless you start a session and register some session variables.
I would appreciate anyone taking the time to explain to me how this works.

1) Usually there is little point putting the request variables
($HTTP_POST_VARS, $HTTP_GET_VARS, $_GET, $_POST) into the local namespace.
Just use them directly as you have here:
switch ($_POST['action']){
case Add Record:
...do stuff...
2) If you really must do (1) then instead of:
extract($attributes, EXTR_PREFIX_SAME, this);
you should probably use this:
extract($attributes, EXTR_PREFIX_ALL, this);
that way you'll know that variables prefixed with 'this' came from
$HTTP_POST_VARS, $HTTP_GET_VARS. BTW why are you processing $HTTP_GET_VARS?
You're using POST for your form.
3) To save confusion use only the new superglobals ($_POST, $_GET etc) OR
only the old, deprecated request variables ($HTTP_POST_VARS, $HTTP_GET_VARS).
Do not mix the two in the same code. See manual for details.
