Why not? I'm guessing because you need to the link to have the
JavaScript variable in it. If this is the case then the href target
should link to a page informing the user that they need to have
JavaScript installed. By doing so you inform them of why clicking on the
link is not having the desired outcome :)

Rob.

ALSO:
<a href="img.php?i=<?php echo($value);?>" onclick="window.location =
this.getAttribute( 'href' ) + '&s=' + s; return false;">
can be altered to be:
<a href="img.php?i=<?php echo($value);?>"
onclick="this.setAttribute(this.getAttribute( 'href') + '&s=' + s);">
What exactly do you need to do, anyways? Maybe there'll be some better
way to do this.

Hello--
I want to send email to 100+ recipients. Two choices I thought of:
1) once call mail() and use BCC, but the negative of this method is that
every recipient in BCC has header "To" same (so I used to put my email
in here - not email of one of the recipients).
2) several calls to mail() function with each recipient's emal
Thanks for ideas,
--Martin

Option 3) setup a dedicated program to handle the mail, such as
"mailman" and then send ONE email from PHP to the listserver which will
then dispatch the mail accordingly, properly, in batches.
http://www.gnu.org/software/mailman/index.html
(at least, that's how I do it currently)

I like #2, within a loop.
E.g.,
// variables defined:
$subject = 'My weekly newsletter';
$headers = [your mail headers here]
$message = "Blah blah \n" .
"and furthermore yada yada \n" .
"and finally so on";
while ( $record = mysql_query('SELECT email from clients etc') )
{
$to = $record[email];
mail($to, $subject, $message, $headers);
}

Hi,
Here's the mission, creating a movie DB, I need the results returned
from mySQL in an XML format for use with the FLASH Professional
DataGrid. Any tips on formating mySQL results would be grand. Here's
the structure of the DB, if needed.
DVD Table
*Title ID
*Title
*Genre
*Actor
*Director
*Producer
*Date Purchased
*Price
*Date Released
*Length
*Plot
*Review(*****)
*Rating
person table
*Producer ID
*First Name
*Last Name
*Director ID
*First Name
*Last Name
Actors_Link
actor_link_id just a primary auto-increment number
person_id
movie_id
role_id

you could easily just print the xml manually.
<dvd>
<titleID>foo</titleID>
<bar>etc</bar>
</dvd>
or, i believe mysql will return XML output but i'm not sure a PHP
function exists to do that.
no need to use fancy DOM functions, outputting XML is easy, parsing it
is when you need to use the special functions and such.

Here's the 'functions_xml.inc.php' file I use, it has served me well and
handles I believe all tag cases, personally I'm a big fan of using the
attributes as they're most easily parsed out in the PHP DOM functions:

header( "Content-type: text/xml" );
print "<?xml version=\"1.0\" encoding=\"utf-8\" ?>\n";

easier for the scripts to parse
//print xmltag('error', array('code'=>'TBD',
'string'=>$message));
print xmltag('error',null, 1);
print xmltag('code','TBD');
print xmltag('string',$message);
print xmltag('error',null, 2);
exit;
}

I made this at one point:
function array2xml($array, $complete = true) {
$xml = "<$array[NODE] ";
unset($array['NODE']);
ksort($array);
foreach(array_keys($array) as $key) {
$xml .= "$key=\"$array[$key]\" ";
}
if($complete) {
$xml .= "/";
}
$xml .= ">";
return $xml;
}
it takes an associative array with a key of "NODE" for the node name
and makes it a single xml node with all the content in attributes. it
even alphabetizes the attributes. special preparing of the data (like
htmlspecialchars()) might be needed to ensure XML compliance.
i made one to translate it into nodes, but i think at the time i read
that attribute parsing is quicker.
calling it looks like this:
$context['NODE'] = "context-info";
$context['current-datetime'] = format_time_xml(time(),"UTC");
$context['current-hostname'] = $_SERVER['HTTP_HOST'];
$context['current-page'] = $_SERVER['PHP_SELF'];
$xml = array2xml($context);

What about the reverse - converting the XML back to MySQL?
(I'm interested for an address book project,
but don't know too much of XML or mySQL!)

Hey,
I've made a nice video where you see ajax in combination with php. and
it works really well although really is misspelled "realy".
Here is the video:

Hi all,
I'm contemplating on a proper way of handling a counter for profile
views on my auto dealership website. I'm currently confused with the
type of algorithm to approach this with.
Say a user has a registered session, and views profile a). I can
increment the counter for that vehicle. The user can then surf
vehicles b,c,d....N etc and I'll increment the counter. However, if
the same session tries to visit profile a,b,c,d should I not increment
the counter? How would you all do it?
Any examples with code would be very insightful and appreciated.
Thank you kindly.

rob, here is tonys definition of encapsulation:
Encapsulation is the act of placing data and the
operations that perform on that data in the same class. The data does not
have to be private at all.
tony did not at any point say that encapsulation is about hiding
implementation details.
im the one who indicated encapsulation is about hiding implementation
details.
tonys definition is contrary to all the definitions i have pulled from books
on object oriented programming (see last post).
actually, its not contrary, but it is only part of the definition.
encapsulation is infact about hiding implementation details; its about
driving client code through a well defined interface, to get access to the
behavior the class supplies.
in order to implement this behavior there are often times variables *and*
methods that client code should not have access to.
i pointed out that classes that do not utilize ppp allow client code to
become dependent upon their implementation. because weve only been
stressing the hiding of member variables (i guess thats what data hiding
means) in this conversation i think we have glossed over the fact that it is
also important to be able to hide certain member functions as well.
this cannot be done in php4, and as i said can lead to systems where client
code is made dependent upon the implementation of other classes, which leads
to very delicate systems.
you guys are not the only php4 advocates ive run into; it just so happens i
have a good friend with a very strong php background who tells me
practically the same thing, ppp isnt that big of a deal. i disagree, why,
is it because ive had a classical education in oop, because ive worked with
a number of languages that dont allow you to create class members without
specifying an access level? for those reasons and because ive had the
misfortune of working in places that have tightly coupled code. im talking
about hundreds of thousands of lines of madness. ppp could have saved these
systems greatly.
Also, don't forget that abstraction, encapsulation, and information
> hiding all have a price.
>
if youre referring to performance i think the price of not using these tools
is also worth mention. namely code which is easily subject to tight
coupling, which as i said leads to systems that are difficult to maintain
and extend.
personally i value maintainability and extensibility over performance, but
thats merely a personal preference.
(tony)

programs

and what exactly does adequate mean? any oo php4 'program' is inherently
weak for the reasons i have sighted, namely the implementation can be
latched onto producing tightly coupled code.
dont worry tony, i can construe some pretty decent php4 code myself; i wrote
a date time package that ive ported to 3 projects including a conversion to
php5 in one of those. the point is that the other developers i work with
dont have a clue about object oriented concepts which in my experience
constitutes the vast majority of php developers. the even bigger point, on
the topic of this thread is that php4 is out the door, so there is yet
another possibly more important reason not to waste time learning oop
studying php4.
ive studied oop for years and worked with a number of oop languages; many of
the bad habits i had at one point or another have been removed. guess what
the first one was, not letting client code access member variables directly
:)
if you dont mind brittle oop code, php4 will suffice. if you want to tap
into real object oriented features, many of which i consider fundamental
(such as ppp [to name just one]) go for php5. truthfully i still think
there are some features missing; interface hierarchies being the main one,
perhaps well get lucky in php6...

Hi,
I'm looking to add some blogging functionality to a website.
I want:
- Articles in categories
- Wysiwyg and images
- Php/mysql/apache
- Readers can comment
- Admin interface
I don't want:
- Website builder / CMS
- To put my website in a blog, rather the other way around
Basically I want to integrate articles into existing pages, something like
<?php blog::getArticlesHTML($rule); ?>
<?php blog::getUserCommentEditHTML($article); ?>
Can anyone recommend a suitable blog script?
Thanks!
