[PHP] OpenCart

[HallMarc Websites]

I am wondering if anyone here can provide some hands-on feedback about this OS 
cart such as can it handle large catalogues of products and high amount of 
traffic? If you don't know about this cart or know of a better cart that is 
more closely suited to fulfill an enterprise level ecommerce need.


Thank you,
Marc Hall

The html, head and body elements are all there. They are
mandatory. The tags however, are optional.

Perhaps you haven't met a few good friends of mine.  Their names are

Right... you do realize that you validate the HTML output of the
executed PHP script, not the PHP script itself.  All you really did
was just show another way to skin the same cat.  Get over yourself.
As for your "more elaborate example", I'm sure that heredoc will
validate nicely.  It also wouldn't hurt to read a book on algorithms
and rethink your code so you aren't processing the same data over and
over again.  I "see this kind of slop all over."

[PHP] What is the best way to process live data?

[Paul Halliday]

For those of you that remember (not likely but anyway) I am working on
some code that splits CLF records and feeds them into a database.

What I need to do now is automate it.

So what I have is a program (urlsnarf) that redirects its output
(simple "cmd > file.txt") to a file. The script currently processes
this output line by line and does the SQL foo - i.e. script.php
/the/file.txt

Should I:

1) do away with redirecting the output from urlsnarf to a file and
have the script run the process and have some kind of handle on it;
foreach kinda thing?
2) keep outputting the info to a persistent file, reading any new
appends and periodically cull this file. Seems like a waste of I/O if
#1 is possible.
3) other options?

Any help/push in the right direction is appreciated.

Thanks.

[PHP] RE: starting session with AJAX

[John Pillion]

Nevermind.  It was a simple mistake - I had "session_start()" on the page
the ajax was calling from, but not at the beginning of the php script it was
calling to. 

[PHP] RE: starting session with AJAX

[John Pillion]

I found two small errors in the isLoggedIn(), which are corrected below.
They don't have any effect on the issue at hand though.  


**
function isLoggedIn($debug = 0){

global $COOKIE_NAME;

// if there is an active session.
if (isset($_SESSION) && $_SESSION['sessDBID'] != '' && $_SESSION['sessKey']
!= ""){

//. check the contents
return authenticate($_SESSION['sessDBID'], $_SESSION['sessKey']);

// or, check for (persistent) cookie.
}elseif (isset($_COOKIE[$COOKIE_NAME]) && $_COOKIE[$COOKIE_NAME] != ""){

$sessInfo = split('-', $_COOKIE[$COOKIE_NAME]);

// . and check the contents
if(authenticate($sessInfo[0], $sessInfo[1], $debug)){

// reset the cookie
return (mySessionStart(true, $sessInfo[0], $sessInfo[1], $debug));
}else{
// cookie authentication failed
return false;

[JP] 

I should say, the logic of a role is essentially the same as the logic
behind a group.  It just adds, as Phpster said, another layer of control

[JP] 

As described, a "role" appears to act essentially the same as a "group" - a
predefined set of permissions that can be assigned to multiple users (as
opposed to a set of permissions unique to the user).  Correct me if there's
a better way, but I think individual permissions can be set similarly -
except skip the role/group step and associate the binary permission string
directly with the user.

Thinking outloud:

In your case where you're dealing with both individual permissions as well
as groups, you could do both of the above, but have the individual
permissions override the group.  You'd have to figure out a "third bit"
though, to act as a "no change" bit.  Ie: 0 = deny, 1 = allow, 2 = NC.  But,
that wouldn't allow you to convert and store the bit string in decimal.

So if group1 had a permission string of 1010, and user Joe was a member of
group1, but you wanted to take away the first bit's permission, and grant
the second bit, you could assign him the individual permission string of
0122 (deny, allow, NC, NC), resulting in his permissions being 0110.

You'd check it by checking the individual permissions first, and if the bit
(or digit in this case) were 2, then you would move on to checking the group
permissions.

[PHP] starting session with AJAX

[John Pillion]

Ok, so I've got an authentication/login form that is "powered by" ajax.  The
user logs in, is authenticated, and the last step is to start a session and
save the necessary information in the $_SESSION vars.

For some reason, it appears (and almost of makes sense) that the session
that is started via the AJAX is lost once the ajax is complete. 

AJAX calls the php, passing username and password
Php executes all the necessary authentication, etc etc
If, login is valid, it calls mySessionStart() (see below)
Checks to make sure the session has been started using isLoggedIn() (below),
which returns true
AJAX closes, receiving a "successfully logged in" message.
AJAX turns around and makes a second call, calling isLoggedIn() again, and
the session is gone

What I'm *guessing* is that because the PHP is not running on the active
page, but "in the background" the session is not being set for the active
page.  Is there a way to pass the session back to the browser?

-   John


Debugging code has been removed for readability:
**

function mySessionStart($persist, $sessionID, $sessionKey, $debug=0){

session_start();

$_SESSION['sessDBID'] = $ sessionID;
$_SESSION['sessKey'] = $ sessionKey;
$_SESSION['persist'] = $persist;

// if persist, set cookie
if ($persist){
return myCreateCookie($persist, $ sessionID, $ sessionKey,
$debug);
}else{
return true;
}
}






function isLoggedIn($debug = 0){

global $COOKIE_NAME;

// if there is an active session.
if (isset($_SESSION) && $_SESSION['sessDBID'] != '' &&
$_SESSION['sessKey'] != ""){

//. check the contents
return authenticate($_SESSION['sessDBID'],
$_SESSION['sessKey']);

// or, check for (persistent) cookie.
}elseif (isset($_COOKIE[$COOKIE_NAME]) && $_COOKIE[$COOKIE_NAME] !=
""){

$sessInfo = split('-', $_COOKIE[$COOKIE_NAME]);

// . and check the contents
if(authenticate($sessInfo[1], $sessInfo[0], $debug)){

// reset the cookie
mySessionStart(true, $sessInfo[1], $sessInfo[0],
$debug);
}else{
// cookie authentication failed
return false;
}

}else{
// there is no session or cookie
return false;

Personally, I have a table for sessions - each time a user logs in, their
session is stored in the table, along with the session_id generated by
session_start(), the userID, the time the session was last active, and an
"active" flag.  I use these fields to keep track of the users activity.  If
at any point the "active" flag is changed to inactive, the user's session is
destroyed, and they are required to log in again.

What you would do in your case, to only allow the user to be logged in at
one location at any given time would be to automatically change the flag to
'inactive' on all the sessions in the table, associated with that users ID.
Thus, if there is an active session elsewhere, when a new session is
started, all other sessions associated with that ID will be "kicked out".

warren's test script above doesn't work so well with tedd's scheme for
naming radios & checkboxs. tedd uses name="option[]" in the markup so in
warren's script, when $nm is 'option', $val will be an array so it won't
convert to a string in ".$val.".

Checkboxes and radio buttons only send their value if the control is

You can have multiple submit buttons (type="submit") on a form, but you
should assign them different name parameters to recognize which one is
clicked (any one of them will cause the form to be submitted, but the only
one that will establish a $_POST entry named "submit" is the submit control
that is named "submit" (name="submit").


I would suggest NOT naming any field submit. There will come a time when 
you will want to do form.submit() in JavaScript and you will find it 
broken in one of the browsers. I'm not sure which, but one of them 
breaks if you have named a field "submit". As a result I always use 
"continue" instead :)

Also, did you browse it directly or through a secondary page ?
It should used on a second page.

i.e.

page1.php

download

download.php

You may also try put these line at top of page to avoid anythings sent before
your attachment headers

error_reporting(E_ALL);
ini_set('display_errors', 1);

Which browsers you used to test it and  their versions ?

There are more methods, I always use:

if($_SERVER["REQUEST_METHOD"] == "POST") {

do_something();

}

RE: [PHP] Re: Best way to test for form submission?

[Warren Vail]

To test a form I usually send the form contents to a php file that contains
the following;

foreach($_POST as $nm => $val) echo "_POST[".$nm."] [".$val."]";
foreach($_GET as $nm => $val) echo "_GET[".$nm."] [".$val."]";

Checkboxes and radio buttons only send their value if the control is
"checked".

You can have multiple submit buttons (type="submit") on a form, but you
should assign them different name parameters to recognize which one is
clicked (any one of them will cause the form to be submitted, but the only
one that will establish a $_POST entry named "submit" is the submit control
that is named "submit" (name="submit"). 

Pressing enter is not sensed by most controls.
Most browsers will look at the field the cursor is positioned on when enter
is pressed, and if it is not one of the controls that response to an enter,
it scans the DOM (list of controls), and will apply the enter to the first
control that responds to an enter, most common is the type="submit" control.


If a select control is between the text box and the submit button (in the
DOM list) the current entry for the select list will be selected and the
form will not be submitted unless the list includes a
onChange="this.form.submit(); " javascript entry.

Be careful designing forms that are dependent on some of these behaviors,
like positioning a submit button to the right of a text box to intentionally
receive the "enter", because different browsers will probably behave
differently.

Hope this helps a bit.

Subject: Re: [PHP] Re: Best way to test for form submission?

I've encountered issue with checking $_POST['submit']
if(isset($_POST['submit'])) {}

If the form consists of checkbox/radio and text field, some of my forms can 
be submitted by just press [ENTER] at the end of one of the text field. In 
this case, the $_POST['submit'] is set even the  submit button was not 
clicked.
However, in some of my forms, $_POST['submit'] will not be set if I submit 
the form by pressing [ENTER] in one of the text field.
So, if the later case happen, I need to remind the user to explicitly click 
the [Submit] button.
I don't know why or in what condition that pressing [ENTER] will not submit 
the whole form include the $_POST['submit'].

Try putting all of that inside of a headers_sent(){} block. If nothing
is displayed, it means that you've already sent something to the
browser, so the headers have already been sent and the extra ones you
are sending do nothing. This sort of thing is shown in your error log
also.

If you still get the tif displayed as text, then are you sure that the
tif is valid?

You should encode the url before printing as usual way
