Re: [PHP] $_POST vs $_REQUEST
sry i gotta disagree. a function that queries $_POST/$_GET first and then $_COOKIE seems much wiser to me. it consolidates all logic in the script, and making that logic obvious by syntax, rather than relying on functionality being determined by php.ini, which could well cause a new developer to lose heaps of time if he/she has to work on it..

Also the behavior of cookies vs. get vs. post are different (cookies have length and expiration limits, get has length limits, post has server confgured limits) The cookie and post/get part is all mixed up now :) I use $_COOKIE when I want cookie information but I know that the data is not to be trusted and is easily fabricated. When reading get or post I just use $_REQUEST nowadays because I don't have to care how the submitting form is written. This makes my form handling data more portable. a. if your updating/inserting/storing data for the user you should require POST in order to mitigate CSRF et al - not to mention using a nonce in your forms. b. when you use $_REQUEST like you do you assume it's either GET or POST data, but it might be COOKIE data ... which will overwrite what is sent via GET or POST in the $_REQUEST array .. which creates a potential for a denial-of-service attack on the users of a site: imagine an 'id' parameter for displaying articles, then imagine a user was tricked into loading a cookie onto his machine for your domain with the name of 'id' and a value of 1 ... said user would only ever be able to see the article referred to be id=1 if you wrote code that took the 'id' parameter from the $_REQUEST var. ... I advocate not trusting any data *and* being explicit about the input vectors on which any particular piece of data is accepted in a given context. (GET, POST and COOKIE are 3 different vectors) Which becomes a moot point if you use the request_order ini setting to specify the ordering of the overriding of variables in $_REQUEST. I do see what you're getting at, and yes there are concerns to be had with one global array overriding another if you don't know to look out for such a caveat. The thing is, there are many times where $_REQUEST is just perfect. Imagine a stylesheet picker, that remembers the visitors choice in a cookie. You can utilise $_REQUEST to handle the whole thing very easily, and in a way that makes sense.

[PHP] obj in array?
Hi folks
I'm hacking on a SOAP2 solution towards Magento and have retrieved the
catalog in an array, but i'm having trouble accessing the values of the
array cause there's an object in it. This is a var_dump of $my_array:
array(14) {
[0]=
object(stdClass)#2 (2) {
[set_id]=
int(44)
[name]=
string(7) Cameras
}
[1]=
object(stdClass)#3 (2) {
[set_id]=
int(38)
[name]=
string(11) Cell Phones
}
how do I access for instance set_id in $my_array[0]? I tried declaring
an instance of $my_array[0] but that fails too: Fatal error: Cannot use
object of type stdClass as array

Kind regards

Re: [PHP] Fun with Streams
Basically... I built the stream encapsulation to do two things for me: 1. Keep track of the row I was on. 2. Keep track of the columns by name. So if I wrote columns Foo, Bar, Baz one time and Foo, Baz the next it would automatically keep the Baz in column three the second time. In other words, it makes it simple to just dump row after row of data into it for exports and simple reports.

This is true. But perhaps more importantly, check() is not a native PHP
function. Thus it comes from some other library or group of external
functions.

[PHP] Database design
Hi all. I know this is not strictly a PHP question but the code will be written in PHP, and I figure the folks here will be well versed in the questions I raise. Please feel free to contact me off the list if appropriate. I need some assistance with database design for a project I'm coding in PHP. I'm willing to pay for the advice, since I think it will be a bit complex. I plan to use MySQLi If anybody feels they can assist, or can point elsewhere please feel free to contact me off list, or reply to the list if you think appropriate. Thanks, Angus
Re: [PHP] PHP Syntax Help - Check?
OK... external function... that would explain why I could not locate it.
Let me get right to the problem I am having with this code as someone
may be able to help directly.
I have a link on a page that opens a contact form. The link is
mypage.php?my_id=5
So on mypage.php, I capture this value with:
$my_id=$_GET['my_id'];
I understand this much. But when the end user submits this contact
form they do so to formcheck.php and if formcheck.php sees a required
field is blank, it throws it back to mypage.php with an alert. BUT, I
lose the value of the variable $my_id. SO, I created a hidden field
on mypate.php with value=?php echo $my_id; ? and on
formcheck.php, I added $my_id = $_Post['my_id'];
However, when formcheck.php returns me to mypage.php, $my_id is still
blank.
Very frustrating.
Any help determining what I am doing wrong is greatly appreciated.
Thanks.

Either way, I'd design a wrapper class around whatever library you use, to simplify error trapping, make the interface simpler and more orthogonal, and improve portability. I've never understood why they didn't provide such an overall wrapper class for the PDO library. Having three separate PDO classes only complicates the interface to the library. Paul -- Paul M.

Re: [PHP] PHP Syntax Help - Check?
if you do the redirection with header('Location: /mypage.php'),
setting a variable on formcheck.php is not enough.
if you modify the header('Location: /mypage.php') to..
header('Location: /mypage.php?my_id=5')
it will take the variable to mypage.php as $_GET['my_id]
you can not expect a variable value set in to $_POST array to reflect
on a totally different page without making it a form post (aka use of
proper headers).
i guess, it's time to you to read about session_start() method and the
array $_SESSION available in php :)

Use the right varialble for the method you're using, so if you're posting, use $_POST, if you're getting use $_GET.. Going by your example, $_GET is what you should probably be using, this is usually the default method if no method is specified on the form tag.

Re: [PHP] PHP Syntax Help - Check?
Hmm. OK with the help below, I am closer.
The other fields on the page are getting passed via form fields that
look like this:
input type=text value=?php echo check('element9'); ?
name=form[element9] size=40 maxlength=255
so I added:
input type=text value=?php echo check('my_id'); ?
name=form[my_id] size=40 maxlength=255
and formcheck.php has:
?php
//start the session
session_start();
//array of fields in form. (In the format field_name = field_label)
$form_fields = array(
element0 = 'Your Name:',
element1 = 'Your Email:',
element4 = 'Item Number:',
.
);
and I added:
my_id = 'My ID Is:',
And this works!
So when I am on mypage.php and I enter a value into the form field
my_id it carries over and repopulates should the form fail validation.
But upon initial load of the page from my link of mypage.php?my_id=5
(so I am not getting there via a form submit) how do I get the value
into the form field?

I have a link on a page that opens a contact form. The link is
mypage.php?my_id=5
So on mypage.php, I capture this value with:
$my_id=$_GET['my_id'];
I understand this much. But when the end user submits this contact
form
they do so to formcheck.php and if formcheck.php sees a required
field is
blank, it throws it back to mypage.php with an alert. BUT, I lose
the value
of the variable $my_id. SO, I created a hidden field on mypate.php
with
value=?php echo $my_id; ? and on formcheck.php, I added $my_id =
$_Post['my_id'];
However, when formcheck.php returns me to mypage.php, $my_id is
still blank.
Very frustrating.
Any help determining what I am doing wrong is greatly appreciated.
Thanks.

Hello all.
I'm trying to learn PHP on the fly and I have a line of code that
contains syntax I can't find documented anywhere:
php echo check('element8');
In the above line, can someone tell me what check means?
In the above, check is a function. It is being called with
parameter
'element8'.
This is true. But perhaps more importantly, check() is not a
native PHP
function. Thus it comes from some other library or group of external
functions.
