Yup. Doesn't work for me either.

I've been working on the md5 stuff recently. Give these files a try and
let me know how they go.

Note that I only have a Mac, so I'd appreciate it if people could try them
on different platforms!

http://mel01.juggernaut.com.au/phplib/crcloginform.ihtml
http://mel01.juggernaut.com.au/phplib/new_user_md5.txt

There are multiple bugs in new_user_md5 fixed, and the crcloginform works
well for me in Netscape 4.7, Explorer 4.5, Explorer 5.0 and Mozilla.

[Phplib-users] Challenge_Auth problem

[Guenther T. <th...@eq...>]

Hi,

I'm using the challenge_auth class to avoid sending passwords in clear
if the browser supports Javascript.
Now this seems not to work with the IE on the Mac.
Everything else seems to work (I tested Win, Linux and Mac-NN)
Is this a known bug?

I tried that, but I couldn't suppress an error message :-(
Actually I found that changing var $Halt_On_Error in db_mysql.inc to "no" 
cured the problem - however, this variable isn't implemented in the other 
database drivers, and I only have access to MySQL so cannot test it on the 
other databases at the present time :-(

Can you confirm how the other drivers react if there is no table present?

Thanks,
Peter.

You're right... at least it won't work on MSSql/ODBC:

Warning: SQL error: [Microsoft][ODBC SQL Server Driver][SQL Server]
Could not find stored procedure 'show'., SQL state 37000 in

Bummer!

I guess you just have to perform the query and see if you encounter
an error.

[Phplib-users] Template Class

[Abu H. <ab...@tr...>]

I saw there is no special variabel to select value, using template (IF), example:

{TMPL_IF VAR=1}
	do 1
{TMPL_ELSE}
	do 2
{/TMPL_IF}

how to do it on template class?

[Phplib-users] Question on subclassing

[Peter B. <re...@f2...>]

Hi,

I understand how to subclass the functions in a class, or add new 
functions.  My question is how do I subclass the var $varname ones?  I want 
to subclass the following:

   /* public: configuration parameters */
   var $Auto_Free     = 0;     ## Set to 1 for automatic mysql_free_result()
   var $Debug         = 0;     ## Set to 1 for debugging messages.
   var $Halt_On_Error = "no"; ## "yes" (halt with message), "no" (ignore 
errors quietly), "report" (ignore errror, but spit a warning)

to allow me to specify debug and Halt_On_Error without editing the real 
classes, which makes it much easier to upgrade PHPLib.

Thanks,
Peter.

[Phplib-users] Test whether db table exists using DB_SQL

[Peter B. <re...@f2...>]

Hi list,

I need to test whether a table exists in the database, showing data from it 
if it does, and showing a button telling the user to "Create the table" if 
it doesn't.  However, all SQL I've tried throws up the following error:

Database error: Invalid SQL: select count(*) as count from sendcard_stats
MySQL Error: 1146 (Table 'sendcarddb.sendcard_stats' doesn't exist)
Session halted.

There must be some way to do this... oh and did I say, it has to be 
cross-db compatible (work on as many of the db_xxx.inc drivers as possible)

Please can someone tell me how to do this?

Thanks,
Peter.

Thanks for the tip, but now I've got problems to get the table-class to
work together with the templates.
Let's say I've got $foo which is sent to the template to replace
{bar}.
How do I get the results e.g. of show_result() into $foo?
I tried $foo.=$table->show_result($db,$class="");
but this just prints out the results and doesn't put them into $foo.
Where is my mistake?

[Layne W. <la...@if...>]

You could do that if you wanted to regex all of the vars in the block. =
My
goal was to gratify my laziness with minimal overhead. I was tired of =
doing:
	$tpl->set_var(array("a_var" =3D> "", "another_var" =3D> "", "yet_again"
=3D> "", "ad_nauseum" =3D> ""));

be reassigned anyway

Look at the function again - that's why it takes a string _or an array_.
	$tpl->clear_var(array("a_var", "another_var", "yet_again",
"ad_nauseum"));

Don't worry, I'm not proposing this as the next best improvement for
template.inc; I simply wanted to show that even though this isn't Perl,
still there _is_ more than one way to do it.

Very precisely stated - In fact, I am vehemently against all attempts to
make templates intelligent (as some people would put it)

PHP itself is intelligent enough :-)

Re: [Phplib-users] templates and tables

[Jesse S. <ph...@sw...>]

You may want to look at the table class.  You pass it a SQL statement
already ran through the $db->query() command and it builds the table for you
from the data selected.  You can even tell it you want to have column
headers and it will pull them out of the select.

For what it is worth, I have extended my template class with a clear_var()
function (below). After parsing each loop, I call clear_var() with the
varname(s) that may be blank. For instance:

while($db->next_record()) {
	$tpl->set_var("some_var", $db->f("some_var"));
	if($db->f("optional_var")) $tpl->set_var("optional_var",
$db->f("optional_var"));
	$tpl->parse("some_block", "some_loop", true);
	$tpl->clear_var("optional_var");
}

I really appreciate it on large blocks with several optional variables.
Here's my function:

	/* public: clear_var(array $varnames)
	 * varnames: array of variable names to be cleared
	 *
	 * public: clear_var(string $varname)
	 * varname: name of a variable that is to be cleared
	 */
	function clear_var($varname) {
		if(is_array($varname)) {
			while(list(,$value) = each($varname)) {
				$this->set_var($value, "");
			}
		} else {
			$this->set_var($varname, "");
		}
	}

OK, I see the point.
Thank you all for the answers.
But there is yet another newbie question... ;-)

[Phplib-users] templates and tables

[Guenther T. <th...@eq...>]

Hi,

as promised here is another newbie question... ;-)
I hope my English is good enough to explain the problem.
I'm looking for an elegant way to get data from a database into a
table.
In this special case, I've got a lot of links which are ordered by a
certain subject. Now I want this links to be put in a table with three
coloumns which is defined as a template.
The template looks something like this:
<table>
{linktype1}
</table>
<table>
{linktype2}
</table>

It's no problem to replace {linktype1} by a couple of tablerows
existing of three coloums whith the links in it, although this doesn't
seem very elegant to me, especially if I (better: the designer) wants a
dot (gif-file) in front of every link. This dot is changing with the
template.

Anybody any hints?

Thanks for your patience.

[Phplib-users] My modifications to template.inc

OK, well here goes :-)

I have developed a way of using PHP in the template files.  Yes I know, the 
whole point of templates is to separate HTML and PHP.  However, in my case 
I had developed a postcard application (sendcard - 
http://www.sendcard.f2s.com/ ) which people were using in existing 
sites.  These sites were using included files for the design, and the 
people didn't want to keep a template with the design in as well, or 
rebuild the site using templates.  So don't flame please, I coded to suit 
my users' needs, which at the end of the day is what it is all about.

Credit for the code goes to Robin Vickery, who very kindly wrote the 
regular expression and function for me (I'm not that good with PCRE).  I'm 
sure my code could be made neater by putting the functions into the class 
as well, but I'm not experienced enough with classes to do so.  Just two 
notes before the code:
1.  It will only work with PHP 4.0.5 or greater.
2.  I subclassed template.inc and copied the whole function loadfile() and 
modified it.  I then stuck the external functions below in the file.


To add the code:
At the bottom of function loadfile(), just before $this->set_var($varname, 
$str); add the following line:

$str = preg_replace_callback('#<\?php(.+?)\?>#', 'evalTag', $str);

And the external function:
/*
  * This function replaces the PHP in the templates with the eval'd equivilent.
  *
  * @author      Robin Vickery <ro...@ec...>
  * @param       $match, the array of items matched using 
preg_replace_callback.
  * @return      The eval()'d version of $match.
  */
function evalTag( $match ) {
         ob_start();
         eval( $match[1] );
         $replacement = ob_get_contents();
         ob_end_clean();
         return $replacement;
}


One other extension I have found useful for template.inc, which I hope will 
be included in a future version, was written by R.B. Scholtus 
<reg...@dd...> and is very useful for deleting a block from a template.

         function del_block($container, $handle) {
                 $this->set_block($container, $handle);
                 $this->set_var($handle, "");
         }


I hope these are useful to some people.  The code is being used in sendcard 
3, which will be released in less than a week, so download it if you are 
interested and try it out!

Regards,
Peter.

Well, it's best to separate PHP and HTML completely if 
possible.  However... there are occasions when you have to have PHP in the 
templates, and I wrote some code which allows you to do so, providing you 
are using PHP 4.0.5 or greater.

Code will follow later...
Cheers,
Peter.

Because templates are meant to separate your code from design.

There are some templates available which allow some sort of meta language
in them but that defeats the purpose of templates.

Templates are typically used for large projects where the designers are a
separate groups and most often at loggerheads with the programmers.

So in a ideal world if you separate design from code then the work becomes
easier and things like changing the looks of the site can be done by the
designers alone.

The concept of templates is to separate the HTML from the logic.
If you start putting logic in the template (whether that's embedded
PHP code or some sort of IF tag) you're creating something *very*
complicated.

Much better (IMHO) to program the logic into the PHP script and
use the template to control the layout of the page.

I have seen one or two cases where if clauses and loops appeared to
be suitable in a template, but in each case I thought the overall
result was more complicated to maintain and configure than it would
have been with the logic all in the PHP application.

My rant isn't particularly relevant in your situation, as the job
you want done is perfectly suited to the existing template.inc :)
