So as you can see they're almost identical except that the OOP version
of fireman didn't need to redeclare functions. True you could have
skipped doing that if you just used the person functions, but then you
may introduce onconsistencies. Additionally, the class version ensures
that the methods applied are those bleong to the concept of fireman
whereas passing data structures around can easily get confusing,
especially if you choose to allow the person functions to be applied
to
the fireman. Going futher, using OOP let's you do all sorts of generic
Hi Rob,
Unfortunately, you still don't understand the problem I have. While it
takes a while to puzzle out the details, I don't have any trouble
reading, understanding or debugging code like this, even though you
skipped completely over several major components (*). I have even
modified existing methods and made minor adjustments to classes, _once
they have been written_.
What I can't do is take a problem description and turn it into classes
that will actually solve the problem. I can usually turn it into
procedures relatively quickly. I can and have built real-time,
multi-tasking and multi-threaded applications on a variety of kernels
and operating systems with no significant trouble. I have written device
drivers, interrupt service routines, message queues and I/O buffering
routines without spending a lot of time thinking about them.
Aaah, you're stuck in procedural mode. In my first year of university
they taught us both C and Smalltalk in different courses and during the
same semester (same semester for me anyways). As such, I didn't form a
bias. Unfortunately they taught us scheme the following year and while I
understand scheme, I have less of a liking for it :)
But defining objects and then figuring out how to create and use them
completely escapes me. My mind simply won't map a problem into objects,
it only sees procedures. Even when I look at classes, they resolve only
as loose groupings of functions and variables, not as unified
components.
And what is a library to you? And a library for which each function
requires on being passed a specific structure type? The structure is
merely the object, and the library routines are the methods. if you can
see libraries and structures, then you can see classes and methods.
If anyone knows how to fix that, please tell me. In the meantime, in my
continuing effort to eschew obfuscation, I will stick with procedural
programming.
It's not for people to tell you how to fix it... it for you to unwire
your head and learn it yourself :)
(*) For example, $this- suggests you have added an array of pointers.
Some are pointers to functions (aka methods) others are pointers to
variables (aka members). [--SNIPPITY--]
You also failed to explain what new does, or parent::__constructor.
What is the relationship between a class and an object? [--SNIPPITY--]
I wasn't teaching your OOP, I was showing that OOP and procedural are
merely different representations of the same thing, and that the
representations aren't all that different.
I get frustrated
because of the extra overhead required to instantiate an object with its
members before they can be referenced,
If you've done C programming then you know you have to instantiate a
pointer to a structure before you should access any of it's members.
Whether you zero out the memory or actually assign values... you are
still instantiating.
instead of simply being able to
use them at any time from anywhere in my code. Likewise, having to pass
a pointer for one object to another object before the second can call
the first is also counter-intuitive. They're all part of the same
application, why doesn't the compiler take care of those details like it
should?
I'm not sure what you mean in the above.
Obviously, I don't expect answers for these questions, but hopefully
this will give you a better understanding of the greater issues
involved. This is a far cry from the Fortran IV I was taught in college
40 years ago. B.M.
I'm sure that's a good thing :)
Cheers,
Rob.

Think it just like a class used for displaying the output (simply put). At least I've been doing this for some time now (the non-OOP part). I have a feeling that someone coming from the procedural way of programming would have problems probably with the templates instead of the development part. -- Thodoris

Can I learn enough this way to determine if a site can be converted from the current state (PHP and XHTML spaghetti) into templates and begin that transformation? Thank you, Bob McConnell HI Bob, Smarty templates are just html files with placholders or variables and simple constructs. This was made to allow web designers to work on a page without having to know PHP programming. Smarty is not an MVC. It is just a class that provides all the necessary functions to replace variables and execute constructs in html page. You just create an instance, set necessary config, do your PHP stuff, assign values to template variables, and finally display. It's just a matter of understanding how its functions or methods work. You don't have to learn OOP and it is not about OOP or MVC. It is just a convenient placeholder of functions necessary to run smarty templates. Spaghetti style programming can be very hard and really time consuming to follow and convert. Just take one step at a time. Maybe I could write a tutorial for this. Just need to find some spaghetti code for the example. Regards, Virgil http://www.jampmark.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP] Smarty Tips and Techniques
The following comment is not intended to be helpful *smacks head on desk repeatedly...* This comment is.. I would hazard to say that if you are unwilling or unable to grasp OOP, MVCs and any decent framework that is necessary then maybe stepping back and tackling only things you can grasp. I do not mean to come across condescending and I apologize if I have anyway; however, I do not see an alternative solution for you. Stick to what you are comfortable with and think about outsourcing the OOP to someone you can trust to write decent code. -Original Message- From: Bob McConnell [mailto:r...@cbord.com] Sent: Thursday, March 19, 2009 11:06 AM To: Virgilio Quilario Cc: php-general@lists.php.net Subject: RE: [PHP] Smarty Tips and Techniques From: Virgilio Quilario That looks nice, but how do I get to the point where I can understand how to use it?

to handle common tasks like DB interaction or filesystem processes.
Yes, I have to deal with both camps here as well. Of five developers
doing PHP at the moment, two are primarily using OOP. But I spent 3.5
years as part of a team developing MS-Windows services in C++. After all
that time, I was only able to write basic functions for others to
convert into methods or classes. I could eventually find my way around
in some of those classes, but it seemed that every time I figured out
what was where, somebody refactored a major component and I had to
start all over again. All I saw was a lot of unnecessary overhead and
obfuscation which made little sense in the long run and slowed down both
the development and the application. The result was a handful of DLLs
that are shared between several products, and each time anything is
changed in one of them, every product needs to be retested to make sure
nothing got broke and some have to be recertified for PCI-DSS as well.
So you are telling me that I can forget about trying to use templates.
Since I can not understand OOP, there is no chance I will be able to use
them.
Just knowing that will probably save me several weeks of frustration.
OOP for those having trouble:
?php
// Procedural:
function person_get_from_db( $personId )
{
// Load person data based on $personId
}
function person_get_name( $personData )
{
return $personData['name'];
}
function person_set_name( $personData, $name )
{
$personData['name'] = $name;
}
$person = person_get_from_db( 1234 );
person_set_name( $person, 'Bob' );
echo person_get_name( $person );
?
?php
// OOP
class DbPerson
{
private $name;
private $otherPersonData; // ...
function DbPerson( $id )
{
// Load person data based on $id
}
function getName()
{
return $this-name;
}
function setName( $name )
{
$this-name = $name;
}
}

It would be best if they also focused on procedural rather than object oriented code. When I started learning smarty, I spent most of my time doing research and that's really tiresome and it is so hard to find examples. Experimented a lot and listed those what's possible, then applied them to my projects. Now to make them handy I posted them to my site so i can have a look whenever and wherever. http://www.jampmark.com/php-programming/16-very-useful-smarty-scripting- tips-and-techniques-to-make-templates-smarter.html As a first step, maybe you should see the crash course at smarty http://www.smarty.net/crashcourse.php Hi Virgil, After your last post here, I looked at your site, then the Smarty site. That was what triggered this question. Templates are a black art to me. I don't even know where to begin to understand them. Every reference I have looked at so far assumes that I already understand the MVC pattern, which is also one of the dark arts. Let me put it simply. I can't grok OO. I tried to do OOP for several years, but it simply does not make any sense to me. As a direct result, I don't understand the concept nor application of patterns. So how do I figure out how to use templates without having to absorb those first? Can I learn enough this way to determine if a site can be converted from the current state (PHP and XHTML spaghetti) into templates and begin that transformation? You don't need OOP to use templates. Smarty is OOP. but there are some lighter faster template solutions, as well as just creating your own templates that you either parse and replace vars in or just use PHP code. As long as you keep the PHP in your templates display oriented and not business/app logic based then it should be a nice solution. You might also look at a framework (codeignitor, cakephp) and go through their tutorial, though these are undoubtedly MVC/OOP, it may make more sense once you start building something with it. Well, I installed CodeIgniter on one of my home servers last night, but have not yet started through the manual. That will be an interesting experiment. I am hoping to create a simple recipe management system there, similar to ReciPants, but in PHP. At work the problem is more basic; 162 files of interleaved database access, business logic and presentation, all written by a civil engineering student with no software training at all. He has moved on, but five of us working on three products are now dealing with the mess he left behind. Thank you, Bob McConnell -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php Just 162 files? I don't mean to sound condescending but if the code is that much trouble, chuck it out and start over. Build it properly by separating out the db interaction stuff ( and there are great patterns to use there as well like Active Record or work with an ORM layer like propel or doctrine ). Then separate out the presentation layer, and define a transport to that layer from the business logic layer. I like XML for this, passing it to XSLT for client side transformations into html. Then the DB passes to the business layer, which does its stuff and then passes the results to the presentation layer. And the same in reverse, the presentation layer never talks to the db layer directly. Creating that separation should make the whole maintenance issue better. Parts that need to be shared can be copied across to the other applications so that each app lives in isolation. If that is not possible, the consider breaking the shared bits into smaller pieces to limit the exposure to potential issues when you have to make changes. PCI is a pain in the ass and the rules that govern that make things very difficult, though I can see why it all needs to be there. The application I support (classic ASP) comprises 149 Mb of code in some 1500 + files scattered across some 50+ folders each with their own db access code. Nightmare isn't the word for it. It uses some 160+ DB tables as well. Rebuilding it is a task that I am looking forward to and am definitely using the MVC pattern with OOP to some extent. I am looking at codeigniter as the framework for this as its is one of the fastest and simplest of the frameworks to work on HTH -- Bastien Cat, the other other white meat
RE: [PHP] Smarty Tips and Techniques
From: Bastien Koert Just 162 files? I don't mean to sound condescending but if the code is that much trouble, chuck it out and start over. Not going to happen. There are too many other tasks in the backlog that are more important and will bring in real money as opposed to just making the developers' lives easier. In addition, the current application has already passed the PCI Level 1 audit, has been deployed and is now handling a thousand transactions per day. If I can slip the changes in piecemeal with those other tasks, fine, but starting over is not even an option. All three products combined are processing more than 10K transactions per day. That spells success as far as management is concerned. With a long list of client requested enhancements already assembled, code maintenance issues are not even open for discussion.

A bad experience with one teacher can hardly convey a trait to all teachers. Cheers, Rob. I'm not talking about a bad experience with a teacher. I'm talking about the use of vague analogies that can be applied to anything and really only get the point across to someone already familiar with the concept. It's a real problem in documentation, partly because the review, if any is done prior to publishing, is by someone else who already has at least a vague understanding of the concept. IBM Developer documentation and Apple developer documentation (IMHO) tend to be better about this than most, but even with them it still is a real problem. -=- Speaking of Car Analogies - in my auto shop class way back when, they used a horse and buggy analogy to show that front wheel drive was better, because horses pull a cart, they don't push it. I then asked where the power in a horse comes from - it's hind legs or it's front legs. The instructor was silent for a minute, then responded I never thought about that, but you are absolutely right That's a serious problem with analogies, they always have serious problems that you can only ignore if you already understand the concept being portrayed by the analogy, and that's why I personally hate them. They seem to be quite popular, however, which is a shame. Just document what the freakin' thing is - analogies just add confusion. In the case of front wheel drive, the issue actually is engine location - not any horse and buggy crap. With front engines, power is lost down the long drive train to the rear wheels. I bet the automobile concept of the a MVC has flaws just as big. A car isn't a MVC, it's a freakin' car, and other than the on-board computer that adds complexity and increases repair cost, programming method isn't part of the design. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit:

So as you can see they're almost identical except that the OOP version
of fireman didn't need to redeclare functions. True you could have
skipped doing that if you just used the person functions, but then you
may introduce onconsistencies. Additionally, the class version ensures
that the methods applied are those bleong to the concept of fireman
whereas passing data structures around can easily get confusing,
especially if you choose to allow the person functions to be applied
to
the fireman. Going futher, using OOP let's you do all sorts of generic
Hi Rob,
Unfortunately, you still don't understand the problem I have. While it
takes a while to puzzle out the details, I don't have any trouble
reading, understanding or debugging code like this, even though you
skipped completely over several major components (*). I have even
modified existing methods and made minor adjustments to classes, _once
they have been written_.
What I can't do is take a problem description and turn it into classes
that will actually solve the problem. I can usually turn it into
procedures relatively quickly. I can and have built real-time,
multi-tasking and multi-threaded applications on a variety of kernels
and operating systems with no significant trouble. I have written device
drivers, interrupt service routines, message queues and I/O buffering
routines without spending a lot of time thinking about them.
But defining objects and then figuring out how to create and use them
completely escapes me. My mind simply won't map a problem into objects,
it only sees procedures. Even when I look at classes, they resolve only
as loose groupings of functions and variables, not as unified
components.
If anyone knows how to fix that, please tell me. In the meantime, in my
continuing effort to eschew obfuscation, I will stick with procedural
programming.
Bob McConnell
(*) For example, $this- suggests you have added an array of pointers.
Some are pointers to functions (aka methods) others are pointers to
variables (aka members). But there is no indication where this array
came from, what it means, nor how it affects the code structure. From
experience I know that $this- is not always needed, but the C++ rules
for when it is or isn't are neither clear nor consistent. There are no
declarations nor assignments for it. It simply adds another level of
obfuscated dereferencing that needs to be done in my head to understand
what is going on.
You also failed to explain what new does, or parent::__constructor.
What is the relationship between a class and an object? I get frustrated
because of the extra overhead required to instantiate an object with its
members before they can be referenced, instead of simply being able to
use them at any time from anywhere in my code. Likewise, having to pass
a pointer for one object to another object before the second can call
the first is also counter-intuitive. They're all part of the same
application, why doesn't the compiler take care of those details like it
should?
Obviously, I don't expect answers for these questions, but hopefully
this will give you a better understanding of the greater issues
involved. This is a far cry from the Fortran IV I was taught in college

As an experienced programmer, please don't laugh too hard at my functions within my class - but maybe this will help you: http://www.clfsrpm.net/xss/cspfilter_class.phps Other than little piddly stuff (that is just as easily done as a function, first class I wrote. A simplified example of it's usage - http://www.clfsrpm.net/xss/index.phps What it does is operate on a DOMDocument object. I'm not really that fond of OO programming either, but in this case it made more sense to view the document to be filtered as objects (xml DOMDocument objects) because it made what the filter does much easier to program. Since I was to be operated on object it made sense (to me anyway) to do it as a class instead of procedure functions. However you will notice that all the class really is - is a bunch of variable definitions (some public, some private) and procedural functions. It's just that they operate only within the scope of the DOMDocument object they are told to operate on. One thing to note - if a function has the same name as the class, it is a constructor and will be run when a new instance of the class is initiated and it MUST be a public function (why I don't understand, I'd prefer it if I could make it private yet still called when a new instance of a class is created). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Smarty Tips and Techniques
That looks nice, but how do I get to the point where I can understand how to use it? I have also looked at the Smarty site http://www.smarty.net/, but their documents assume significant experience in building and using templates. Where can I find guidance or tutorials on how to do all of this, starting with only a rudimentary knowledge of HTML and PHP. It would be best if they also focused on procedural rather than object oriented code. Bob McConnell -Original Message- From: Virgilio Quilario [mailto:virgilio.quila...@gmail.com] Sent: Wednesday, March 18, 2009 10:36 AM To: php-general@lists.php.net Subject: [PHP] Smarty Tips and Techniques Hi list, Just wanna share my collection of Smarty scripting tips and techniques. Smarty is a template engine for PHP that you can use to separate data and logic from web design. This way programmers can work on the php scripts and designers can work on the templates for the same web site. Here is the link: http://www.jampmark.com/php-programming/16-very-useful-smarty-scripting- tips-and-techniques-to-make-templates-smarter.html Hope you find it useful. Virgil I have stared using smarty myself in a recent project I am still making and I'll have to say that it has its virtues. Look at a simple example in the smarty's site and use the manual for any questions. You will probably find some stuff by googling. The templates (simply put) are actually html-like that has some php variables inside you may assign before displaying the actual template. This way you customize the template to output what you need. Above that you may start using the statements to automatically build forms, tables etc I like the fact that there is a cache and that the templates get compiled which make them faster to process. Nevertheless you need time to get familiar with the smarty way of thinking as with all frameworks and template engines you need to use. -- Thodoris -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

So apply the stripping and replacements to the content you have saved, but don't modify the saved content itself. You can add another field to the same table containing the data called formatted_content and save it alongside the original. The tags are being inserted by Microsoft when you copy/paste from one medium to another. I do beleive MS detects you are pasting from a Word document to an HTML format and transparently performs the conversion for you.

Re: [PHP] PHP, Smarty, and Text
One way to balance the author's need to have nice-looking output, and your need to keep the content/html under control is to provide the authors with a variety of template layouts with varying number/placement/sizes of images and blocks of text. Build a half-dozen of them, allow only ASCII text input, let the author pick their poison, and Bob's yer uncle, for many clients/projects. Make them generic enough and re-use them forever. :-) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This way you can str_replace all that user enters in to watever class or text u want to to make it look pretty.

RE: [PHP] PHP smarty - nested queries and arrays
First I'll appologize for the cheuvanistic remark the other poster had. I
know he had good intentions...
So I don't know smarty, but it seems to me you're grabbing only one row
here:
$projects = $db-getAssoc()
Normally in straight PHP, I would do something like.
While ($row = $db-getAssoc($query, DB_FETCHMODE_ASSOC))
{
$projects[] = $row;
}
The [] just adds a new element to the array and is dumping in the entire
$row array to it.
Ala, multi-dimensional array.
Then I would do something like:
foreach ($projects as $key = $value)
{
echo [.$key.] has a name value of .$value['project_name'];
}
Remember that you have a multi-array in $projects, so that's why I split it
into the key/value pair where value is actually another array, and you
access the elements via it's hash key.
Hope this helps.

[PHP] PHP smarty - nested queries and arrays
Hello!
I'm using PHP and Smarty to try to build an array of arrays using the
results from nested queries. I am just learning about nested arrays,
and I'm not sure what I'm doing wrong.
I am hoping someone can give me a hint as to what I am doing wrong. I
looked on php.net, but still couldn't figure it out.
If I remove the PHP foreach loop, it works fine, except, of course, no

seeing it.
I get the following error with the code below:

You should check your Smarty`s template_dir. Put the templates into the
template_dir, then the Smarty will find them.
Like this:
$smarty = new Smarty();
$smarty-template_dir = '/home/mike/tpl/';
$smarty-display('test.tpl');
You should put the file 'test.tpl' into dir '/home/mike/tpl'.

Re: [PHP] SMarty and commercial php (a little 0t)
I'd recommand you to use the HTML_TEMPLATE_IT. It's a PEAR class for templating; I've personaly worked on it for building skinnable applications in which users and admins can change the look of the pages. Bottom line, it's a PEAR library/extension so no hastle since most of the hosts include it in their PHP installations. This template does alot of handy jobs such as nested blocks templating and rendering. However, it does not have the bells and the whistles of Smarty. Simply it does the job, it's efficient, and very elegant since your HTML templates would have only 2 extra stuff. One which is the HTML style comments to define and close blocks and the, Two which is the variable names to be placed whithin curly braces. So templating does not realy have a language in IT it's just a ditributed method of writing HTML and feeding data which forms another Tier in your application not another Application by itself. Benefits you'll get by using this PEAR library/extension is that you wouldnt need to tutor the designers on how to use a procedural markup templating language hence more flexibility and shorter learning curve. And plus it does not need no configuration and you could write your own nice wrapper classes to do special things for you, such as rendering pages templates, or blockwise template files with predefined variable to be inserted in the template files simple as that. e.g. you could write a function or a class method to route template files and then only pass them an array and the function would do the whole thing from rendering to displaying. especialy if you use the Web Standards and Semantic Design skinning would mean only switching CSSs and slight changes in your structural markup(template files). Note: If by any change your ISP/Host does not have the PEAR package installed you could just put it in a directory and simply append it to your include_dir directive so that you could include/require the class file (only 1 file is the whole package) directly w/o routing to its location. I'd honestly never implement Smarty for an application I'd work alone on and then give it up to designers I'd use Smarty while working with team mates of the same range of understanding of the Web Dev/ Design in a team environment for better performance and that's only if the application screens are more than 100 and the administration.

[PHP] SMarty and commercial php (a little 0t)
Hey, This may belong more on the smarty list, but I thought i'll ask it here because in another way I need your opinion more than smarty advise. Like a lot of people on this list, I use a templating system (Smarty and another... mostly Smarty) when I am working on a project for a client... Reason: when he wants to make a design change..I dont kill him...or his family :-) Now I am faced with another situatation, I have been assigned a project (working freelance) to make a pretty simple piece of software which also includes 2 admin panels (one for client and one for admin) He wants to be able to skin the admin panel at will, which means, easiest solution: Template the sod. I was wondering if its a good idea to template via smarty and include smarty with my code? also instructions to setup smarty when setting up the application i made? Searching google I found this very nice place discussing PHP templating (you might also want to read up on how many there are!) http://www.sitepoint.com/forums/showthread.php?t=123769page=1pp=25 but no discussion of including any of these with commercial software for the client to setup and their results.

[PHP] smarty and db
Ok, I am starting a new job and learning a new person's code, and trying
to learn Smarty at the same time.
This question is so basic, but I have no idea where to look for an answer.
ANyway, I need to change the code so that, when there are no row returned
by the database, a message is displayed saying, There are no events
scheduled. or what have you.
Now, the way I would have done this before using smarty would be to check
the number of records, and if there were none, I would display the
message, otherwise, I would loop through and display the results,
However, I know one of the points of smarty is to keep code out of the
presentation layer, so I don't want to go into the template and add an if
statement in there.
Any help directing me to an example or whatever would be helpful.
Here is what is going on right now in the code:
(in the PHP page)
$events = $db-getAll($sql_events, DB_FETCHMODE_ASSOC);
$tpl-assign(events,$events);
(in the template page)
{section name=id loop=$events}
tr
td class=event
b{$events[id].type}/b: a class=menulink
href={$url_prefix}/community/events/?id={$events[id].id}{$events[id].date|date_format:%B
%e, %Y}, {$events[id].speaker}/abr /
{$events[id].title}
/td
/tr
{/section}

by the database, a message is displayed saying, There are no events
scheduled. or what have you.
Now, the way I would have done this before using smarty would be to check
the number of records, and if there were none, I would display the
message, otherwise, I would loop through and display the results,
However, I know one of the points of smarty is to keep code out of the
presentation layer, so I don't want to go into the template and add an if
statement in there.
Any help directing me to an example or whatever would be helpful.
Here is what is going on right now in the code:
(in the PHP page)
$events = $db-getAll($sql_events, DB_FETCHMODE_ASSOC);
$tpl-assign(events,$events);
(in the template page)
{section name=id loop=$events}
tr
td class=event
b{$events[id].type}/b: a class=menulink
href={$url_prefix}/community/events/?id={$events[id].id}{$events[id].d
ate|date_format:%B %e, %Y}, {$events[id].speaker}/abr /
{$events[id].title}
/td
/tr
{/section}
Thanks,
Amanda
According to this page
http://smarty.php.net/manual/en/language.function.if.php you should be able
to do something like.
{ if is_array ( $events ) }
do smarty stuff
{ /if }

My solution to this would be to change the template. IMHO it's a
view funciton to display something different when there is no data.
However, if you're averse to that, I would suggest using a different template.

So there are alternatives to what Smarty offers, but I also said I just see them [template engines] as another tool. It's a tool; use it where it saves time, but it's not as if native PHP lacks most (if not all) of what Smarty offers, which is what I originally thought because I'd learned PHP by spaghetti coding.

Ugh that's not just fuckingly ugly, but a total doom to maintain over the

It maybe faster, it maybe a bit simpler since you only have to learn one

$result = mysql_query (SELECT * FROM users WHERE id = '.$_GET[id].');
$row_array = mysql_fetch_array ($result);
$page-assign(name,$row_array[name]);

$page-assign(state, $row_array[state]);
$page-display(template.tpl);
---
html
body
Name: {$name}br
Address: {$address}br
State: {$state}br

Better than this?

$result = mysql_query (SELECT * FROM users WHERE id = '.$_GET[id].');
$row_array = mysql_fetch_array ($result);
$name= $row_array[name];
$address = $row_array[address];
$state = $row_array[state];
$include(template.tpl);
---
html
body
Name: ?=$name;?br
Address: ?=$address;?br
State: ?=$state;?br

They both look about the same (well in the native PHP example I actually
wrote less code).
Perhaps you were looking at my spaghetti-code example, but take another
look, I posted 3 examples.

You'll raise an Error Warning without first passing it through some kind of test (or function). You assume that the PHP short-tags are enabled (? ?) for echoing variables and while most the time they are, you shouldn't bank on it in code (incidentally, you don't need the trailing ; on the short-tag echos). Sure - these things can be fixed easily, but then that isn't the point - if you think about it logically, anything Smarty can do, PHP can do too (well, duh! :) But what if you want to take your template and perform a bit more than just mere variable substitution on it? How about highlighting all words that match a search term, or applying logic to a display block based on a user status?

Re: [PHP] smarty
Kelly Hallman said: I don't recall anyone ever advancing the notion that Smarty turned PHP into something more than it was before. By definition it is merely a layer that makes your life as a developer easier. A tool! Yeah but in my ignorance that's what I thought, and I realized I probably was not alone. However, those of us who are seeing great benefit from the use of Smarty are not mere ignoramouses, and I feel that the implication being made is that we're not seeing what PHP can already do. This is false. OK but I was an ignoramous and I believe there *are* others out there like myself. The reason this is such a contentious issue, I think, is because the point being made--while correct, and note-worthy--is short-changing Smarty by calling it redundant. I feel that one's use of Smarty may indeed be redundant, that's easy to do. However, Smarty is not inherently redundant. Using Smarty redundantly does not make Smarty itself one bit redundant. I said it was mostly, not completely redundant. In the case of the cool built-in functions you've got some advantages. But I believe those could also be (perhaps more effectively) implimented with other libraries. It's just a tool. To make that claim, you're dropping a pretty heavy dis on a lot of people who have invested a great deal of time, effort, and subsequently realized great benefits from Smarty and it's templating brethren. Not to mention all those who have devoted great effort in the development of these tools. I believe it and most templating engines were written because many people didn't know they had an alternative. I could be wrong; if so, it is a heavy dis. Didn't mean it that way, so if I am wrong I humbly apologize. I'm seriously not trying to sound harsh here, but do you think that by realizing you could structure your PHP code in such a way to mimic a basic Smarty template, you've now single-handedly debunked the purpose for all of this effort by so many avid PHP programmers? Seriously, now...! Naww... I'd been using Smarty for several weeks now because I thought the only alternative to spaghetti code was Smarty, but recently I realized that it's not, and that simple example shows it. I didn't realize I had another alternative. It's like this: Does your mother know you're stupid? Either way you answer, you're stupid. If you don't realize you have another alternative you're stuck. I believe Smarty was written because people didn't realize they had the other alternative. If I am wrong, see above. Regardless of the merit of the point being made, I don't think that benefits anyone much. I'm sure when some guy came up with a metal knife, there was a dude there with a sharp rock saying, but this works too! Then the guy with the knife started using it to cut everything, while the rock required constant honing to remain sharp enough to do half the work. But the guy with the rock thought it was all he needed! I use a knife. I see what you mean, but my point is PHP already *is* the knife: it templates with about the same effort as Smarty. At times less effort (in which case I'd use native PHP), at times more (in which case I'd use Smarty).

Because you're injecting variables directly into your HTML, which some
of the time might be ok - but what if the $row_array doesn't contain
name ? You'll raise an Error Warning without first passing it
through some kind of test (or function).
Only if you have error_reporting() set high. If you have a PHP templating
solution, you'd turn error_reporting() down when you included the PHP
templates so you didn't get a warning.
You assume that the PHP short-tags are enabled (? ?) for
echoing variables and while most the time they are, you shouldn't bank

You're relying on web-server writable directories when you use Smarty. It's
all a trade-off.
But what if you want to take your template and perform a bit more than
just mere variable substitution on it? How about highlighting all
words that match a search term, or applying logic to a display block
based on a user status?
You can do this with output buffering and PHP functions. Smarty just
provides you a different interface.
?php start_highlight(); ?
Paragraph Text
?php end_highlight(); ?
vs.
{section type=highlight}
Paragraph Text
{/section}
Yeah, I know that's not quite the Smarty syntax, but you get the idea.
Smarty just provides an easy interface to a lot of these things. It's a
tool, like a lot of others have said. :)

1st. Clarity. It's much more clear to me to take a look at a template and
identify a subsituing variable when it's marked as something different like:
{$var} than the uglyness of ?=$var ? -and if you follo the recommended way:
?php=$var ?
2nd. As other users pointed, error handling.
3th. Lack of temptation. If I start putting pure php code on my templates it
wouldn't be long before half the application logic ends there, we'll know
what's to code under tight schedules. Smarty by separating my presentation
logic from my bussines logic helps me avoid spaghetti code.

You must be disciplined in any case. Smarty has loops and custom
functions and can even include real PHP. You just have to be disciplined.
Appart from the ton of small features that smarty gives you like caching,

Caching/popups/variable modifications can be easily added with native PHP
functions (that perhaps people aren't aware of) or with external
libraries/classes. Smarty has them all under one roof, making it an
excellent choice -- when it's needed.
My point is that it isn't always needed, as I thought it was. I'm sure
others believe it's their only choice.

Seems that Smarty is, for the most part, redundant (see my last post called PHP makes a great templating engine (Was: smarty)). I was not intending to pronounce Smarty redundant; on the contrary if anything - but thats not the point... but I think calling Smarty a template engine confuses the issue - it would be clearer call it something like 'Presentation Component' which encapsulates output caching, output string transformation, markup generation, presentation logic security seperation of (code possibly human) tasks. viewing it as a component means viewing it as a tool, tools are used when appropriate and according to their capabilities and the scope of the job at hand. in principle a sizeable proportion of all the. Tool. Look at it as just another tool. I was seeing it as a must have because I was somewhat ignorant of PHP's native capabilities. It adds complexity and does indeed slow down your program (the Smarty class must load on every page) so keep those in mind. On the other hand, you're the Smarty core is smaller than, for example, PEAR::QuickForm (if you use all the plugins its about 40% larger) - and PEAR::QuickForm is usually used with a Renderer (e.g. Smarty!!), think of it like this: how much do you charge per hour, what does an extra CPU cost how much, if any, time does Smarty save you. (besides which I think its quite easy to develop something in Smarty which does what QuickForm does but more transparently and with alot less hassle - IMHO). Code is code; it might not be perfect but it might scratch an itch. almost forced to separate business and presentation and you gain caching Smarty does force that at all; you have to make the distinction and apply liberal self-restraint. (though native PHP options or Zend are available). So it's a weighty decision. But it is a good tool. Realise that Smarty (usually) only re-compiles the template if it changes. The compiled template are full of generated PHP - there is little overhead in including that. if you use a native PHP option then: a, what is Smarty? (not important!) b, what are the chances that your output code/module/class/etc will not employ similar solutions to something like Smarty? because broadly speaking 3. 'Lock In' I believe Lock In is a big problem unless you document well. For instance, my supervisor is probably going to choose ASP.NET (don't ask why) for our next project. But all along, I plan to document it well in case we hit a stumbling block. With a bit of effort and the source code I can port it to PHP. I've even toyed with the idea of keeping a fully-functional copy written in PHP while he's working in ASP.NET ;-) But I've got better things to do. Limitations are often purely percieved rather than actual I believe that's why I chose Smarty for my last project. I thought PHP limited me to keeping business logic mixed with presentation logic, but it's hardly the case. and funnily enough Smarty is actually a pretty good example of a possible PHP based solution to the problem logic seperation. When you consider that it's just another tool in your box, it works well. It's not the only way to let designers design and programmers program (Jochem is a big believer in CSS for that).

Smarty, as you know, basically takes a Smarty template and writes PHP code similar to what you've done above, then writes out the .php file, and includes it when you render your template. So you'd get nearly the same effect by writing the PHP as a separate file and including it as your last step, and it acts as your display logic. That may be acceptable to you, as a PHP programmer. If you're the only one who ever needs to modify your templates then that's great, more power to you. I'm sure that you would have no problem having many levels of nesting all over the place and not screwing anything up. So be it. But that's you. I guarantee another person not as adept at PHP will screw that code up, and there is less potential for that with a Smarty template. If you know PHP as well as yourself, it should be plain to see how Smarty is just a wrapper over PHP that makes templates easier to build and maintain. For a designer or non-coder, Smarty will be easier to learn than PHP. Unless your needs never exceed the very basics like you have demonstrated above, you'll be hosed when another person needs to modify your template. Which goes back to a templating truism never in dispute: if this is all you want templating for, it's six of one, half a dozen of the other. However, there are practical limitations on what you can easily accomplish with this approach, and Smarty addresses those issues. And you're worse off if you invest a lot into building your sites this way, and then realize you need some better templating strategies later. You can still separate your logic from your presentation, template designers can still use quick, simple tags to include code, and the upside is that people familiar with PHP don't need to learn ANOTHER language (that's what Smarty is) -- they can dive straight in. You can consider it it's own language, but really it's more like PHP with different formatting. Which is why it's different than what you're doing above--it's designed to facilitate templating. Your method is just poking in variables and PHP into inline'd HTML. It works, but you're missing some of the power of Smarty if you think that's all it's good for. The question is, do you want to give your templater designers full access to the power of PHP, or not. In other words: are your template designers already good PHP programmers? It's not just hype, it solves real problems, even if you don't have them. Smarty is a bit of a hack too... why do I need to declare my templates within the PHP code? If I'm an HTML designer I'd like to create a new page, include templates, use some data that's been made available and have it all in the template. I sure as heck wouldn't want to have joe programmer edit the main page, add support for importing my template. This is the thing that bugs me about Smarty, its still got that hanging dependency. And it's still got to include all those templates within the source code. InterJinn is superior in this respect. You use XML tags to import other templates, you use XML tags to load modules and components, and you use XML tags to do almost any kind of expansion you want. Of course, you can go ahead and use something else, InterJinn provides the ability to plug in custom compilers. InterJinn compiles to PHP code, includes are INCLUDED at compile time not at run time. So given this scheme anyone working on the HTML is already familiar with the syntax... hard to go wrong with: jinn:template path=topnav.template/ Hell you can even overload HTML tags. Not only that but Interjinn allows recursive includes of templates and source files, and these includes can be relative to the outer nested template or source file. Furthermore, there's nothing forcing the use of the InterJinn application layer so InterJinn can be used entirely for it's templating features, in which case it provides a faster resulting PHP page than using PHP include().
