[PHP] Re: Recursion issue with Zend_Soap_AutoDiscovery.

Hi.
I'm in the process of building a web service which incorporates the
ability for the server to inform the client that a particular call has
been superseded by another.
So, cut down (I've removed all the other details), ...
class ServiceDetails
{
/**
* Superseded by
*
* Details of the replacement service that is now available.
*
* @var ServiceDetails
*/
public $SupersededBy = Null;
}
When I try to use Zend_Soap_AutoDiscover() against this class, I get ...
Infinite recursion, cannot nest 'ServiceDetails' into itsself. (sic)
There has to be recursion, as there could be many levels of
supersedence, each one providing the details of their own replacement.
The call to return the service details read the requested
services/class constants. If there is a superseded entry, it creates a
new request for service details on the new class (the recursion).
If the value is Null, then there is no recursion.
I'm using ...
new Zend_Soap_AutoDiscover('Zend_Soap_Wsdl_Strategy_ArrayOfTypeComplex');
as the strategy as the service has arrays of complex types in the output.
If I use @var string and then manually replace the type in the WSDL
file from ...
xsd:element name=SupersededBy type=xsd:string /
to
xsd:element name=SupersededBy type=tns:ServiceDetails /
and use wsdl2php against this, it all _SEEMS_ to work OK.
So. Is this my best option? Or is there a way to do this that I'm missing?
Any ideas really.
Is this even a bug in the Zend_Soap_AutoDiscover class?
Regards,
Richard Quadling.

I amended Zend_Soap_Wsdl_Strategy_ArrayOfTypeComplex::addComplexType().
Changing the (sic) ...
throw new Zend_Soap_Wsdl_Exception(Infinite recursion, cannot nest
'.$type.' into itsself.);
to ...
return tns:$type;
and all is working just fine.
Obviously, I may be breaking something here, but I've not come across
it yet. Early days !

Not yet! I'm on windows and I'm not confident enough to put extensions
I've built out on the live servers.
Also, it is using VC8 and I'm on 5.3 (VC9, x86, nts). So not tested.

Re: [PHP] Re: Recursion to sanitize user input
Hi M
I don't understand. I don't think I'm storing it anywhere. I have it
looping through all the POST variables. If it's not an array then the
sanitize function returns a sanitized value. If it's an array then the
sanitize function calls itself again and again until it finds a single
variable and returns it as a sanitized value.

[PHP] Re: recursion?????
Alex,
as a general rule of thumb, try to do as much checking as you can with
JavaScript. For those checks such as is the field a valid date, is
the field numeric and so on, it is much faster to check on the client,
than to send the data back to the server and check it there. Probably
the best way to do this is with an onSubmit clause on the form.
Something like:
form name='RegisterForm' action='register.php' method='post'
onSubmit='return checkRegisterScreen(this)'
Some things you cannot check on the client, for example does the value
of the field already exist in a data store on the server. There are
many ways in which you could check these fields. On of the easiest to
understand ways would be to name your submit field something like
Register, and use code something like the following in register.php:
switch ($_POST['submit']) {
case a;
processA();
break;
case b;
processB();
break;
case Register;
checkFormAndRedisplay();
break;
default;
processDefault();
break;
}
In the procedure checkFormAndRedisplay(), you can write code to check
your fields, and the relationships between them, and then redisplay the
form with appropriate error messages, and highlighting, to guide the end
user to correct his errors.
Hope this helps. . . Fred

Ok ... here is the sitituation... I am creating a registration form.
What I have so far works ... the user registers using this form and the
form calls another page that will check the validity of the data
(checking for username availability, etc...). If there is an error,
display the error and have the user GO BACK AND TRY AGAIN - This is
the problem I want to fix.
What I want to do is have the registration form, on submit, check the
data validity right then, if there is an error, redisplay the form with
an * next to the field that is incorrect. This way the user does not
have to go back and try again, it will be there in front of them.
Basically, have the form action call itself hince the recursion.
Any suggestion/examples?
Thanks,
-Alex

[PHP] Re: Recursion?????
Alex, and Michael,
here is a code fragment which I have cut and simplified from one of
my working scripts, that does some simple javascript checking of a form.
It should give you an idea of how to do it. There is a lot of
documentation, and examples of javascript on the web. Try a google
search. At this level it is relatively easy(well at least it is after
you have done it once). When you get into more complicated javascripts,
you have to take into account that because of different document object
models, some things are implemented differently in different browsers.
. . .
?
head
script LANGUAGE=JavaScript
!-- Hide from older browsers
var whitespace = \t\n\r;
function isEmpty(s) {
// +--+
// | Return true if the string s is empty |
// +--+
return ((s == null) || (s.length == 0))
}
function isWhitespace (s) {
// +---+
// | Return true if s is empty or contains only whitespace |
// +---+
var i;
if (isEmpty(s)) {
return true;
}
for (i = 0; i s.length; i++) {
var c = s.charAt(i);
if (whitespace.indexOf(c) == -1) return false;
}
return true;// must be whitespace
}
function checkRegisterScreen (form) {
// +---+
// | Return true if all fields on screen are valid |

if (isWhitespace(form.userid.value)) {
alert(Userid may not be blank);
form.userid.focus();
return false;
}
if (isWhitespace(form.username.value)) {
alert(User name may not be blank);

}
return true;
}
// End of hidden section --
/script
/head
body
form name='RegisterForm' action='Register.php' method=post
onSubmit='return checkRegisterScreen(this)'

. . .
The key thing to notice here, is that the submit will only happen if the
onSubmit returns true.
Hope this helps. . . Fred

Re: [PHP] Re: recursion?????
David, of course. You always should check in the server, even if javascript is working. You have to protect your data integrity. Sorry I did not make this clear. The benefit of checking in javascript(which I suspect is enabled in most browsers these days), is that the client gets an instant response for the out of line situation. Best regards. . .

Thank you so much! This eases my worries for next semester. Would happen to have an example script showing PHP using recursion? Thanks again! Martin wrote: Hi Andres, Yes, PHP support recoursion. That means, that you are calling a function again and again, but with new start-parameters. For example, if you want to search a harddisc for a file, you will call your function SearchFolder($path) with C:\. If the function itself detects subfolder, it will call itself, but with the parameters C:\Subfolder1, C:\Subfolder2 and so on. You have to watch out then, the the function terminated correctly, if the searched file is found.
