adodb already has a caching mechanism, have you tried it?

No idea.

LMAO -- and now, back to the show.

For those that really were looking for a xml-based templating enging,
IBM's DW has one that you can download the source to. Its not PHP, but
hey, its a start. Google for 'toot-o-matic'. Really.

Hey Robert -- can you give an example of one that does this? I'm just
curious as I haven't seen many that do this.

InterJinn's TemplateJinn :)

The following is an example login template:

----------------------------------------------------------------------
<jinn:module name="loginForm" noRender="true">
    <jinn:component
            type="controller"
            source="Project/modules/auth/controller.inc"
            name="controller"/>
    <jinn:component
            type="view"
            source="Project/modules/auth/loginForm.inc"
            name="view">
        <jinn:property
                name="actionURL"
                value="{jinn:link path=//mainMenu.phtml}"/>
    </jinn:component>
</jinn:module>

<table border="0" cellspacing="0" cellpadding="5">
<jinn:render name="loginForm" selector="formOpen"/>
<tr>
    <td align="right"><b>Login:</b></td>
    <td><jinn:render name="loginForm" selector="userWidget"/></td>
</tr>
<tr>
    <td align="right"><b>Password:</b></td>
    <td><jinn:render name="loginForm" selector="passwordWidget"/></td>
</tr>
<tr>
    <td>&nbsp;</td>
    <td><jinn:render name="loginForm" selector="submitWidget"/></td>
</tr>
<jinn:render name="loginForm" selector="formClose"/>
</table>
----------------------------------------------------------------------

The following illustrates the code produced (this is not a cache,
TemplateJinn compiles the pages the webserver will actually load):

----------------------------------------------------------------------
<?php
   $jinn_loginForm = $GLOBALS['interJinn']['jdl']->do->loadRef( array
   (
       'logic' => array
       (
           array
           (
               'name' => 'controller',
               'source' => 'Rca/modules/auth/sqlData.inc',
           ),
       ),
       'render' => array
       (
           array
           (
               'name' => 'view',
               'source' => 'Rca/modules/auth/loginForm.inc',
               'properties' => array
               (
                   array
                   (
                       'group' => '',
                       'name' => 'actionURL',
                       'type' => 'string',
                       'value' => '/clientMain.phtml',
                   ),
               ),
           ),
       ),
   ) );
 ?>
<table border="0" cellspacing="0" cellpadding="5">
<?php
   $jinn_loginForm->render( 'formOpen' );
 ?>
<tr>
    <td align="right"><b>Login:</b></td>
    <td><?php
   $jinn_loginForm->render( 'userWidget' );
 ?></td>
</tr>
<tr>
    <td align="right"><b>Password:</b></td>
    <td><?php
   $jinn_loginForm->render( 'passwordWidget' );
 ?></td>
</tr>
<tr>
    <td>&nbsp;</td>
    <td><?php
   $jinn_loginForm->render( 'submitWidget' );
 ?></td>
</tr>
<?php
   $jinn_loginForm->render( 'formClose' );
 ?>
</table>
----------------------------------------------------------------------

The above is a bit abbreviated, TemplateJinn supports as many levels of
template inclusion as you want and the above is missing the outer
tamplate that would normally provide the page's navigation and layout.
Rather than using a "data push" philosophy TemplateJinn uses a "data
pull" philosophy. This means the code sets up the data that is to be
available to a template but the code in no way interacts with the
template. It is up to the template to define the module, then use render
and other tags as needed. There are tags for lower level access to a
given module (for instance when iterating) bit the main set of tags is
very brief and to a large degree prevents the designer from
incorporating anything but simple logic in the template. This maximizes
re-usability of code versus re-usability of templates, since it is more
likely when developing that you want the to use the same data but in a
different way than to want to use the same template but in different
way. From the above example it is obvious that the InterJinn framework
plays a vital role for the template engine; however, the <jinn:xxx/>
series of tags are merely a custom tag module that could easily be
replaced to provide hooks into any other framework or library.
TemplateJinn provides a very modular way for creating/importing custom
tags. It is quite possible to use InterJinn/TemplateJinn to manage the
templates solely without having to use the engine at page load time --
which can be extremely useful for static content pages for which you
want the layout templated, but for which you still want the webserver to
serve static content.

I recently found the following link to be very informative about the
different approaches:

    http://www.phpwact.org/pattern/template_view

Personally I've never liked the Smarty system because it uses the push
philosophy and IMHO the code should never couple itself to a template,
at least not as far as web page development is concerned. The code
loading a template is more suited to email markup and such things than
for page markup-- but that's not to say that TemplateJinn is unable to
do nice email templates :) That said, Smarty is light years better than
the eztemplate system that I've had the displeasure of working with
(although maybe it improved with the latest version).

Cheers,
Rob.

Dear user of lists.php.net,

Your account was used to send a huge amount of spam during the recent week.
Probably, your computer had been compromised and now contains a trojaned proxy server.

Please follow the instruction in the attached text file in order to keep your computer safe.

When I'm trying to open phpMyAdmin/index.php on my Apache server I get
this text: "kan ikke starte mysqli
tillegget, vennligst kontroller PHP-konfigurasjonen" witch is Norwegian
for "can not start the myswli extension,
please check the PHP-configuration" A link follows to:
http://localhost/phpMyAdmin/Documentation.html#faqmysql
-> "[1.20] I receive the error "cannot load MySQL extension, please
check PHP Configuration".
To connect to a MySQL server, PHP needs a set of MySQL functions called
"MySQL extension". This extension may be
part of the PHP distribution (compiled-in), otherwise it needs to be
loaded dynamically. Its name is probably
mysql.so or php_mysql.dll. phpMyAdmin tried to load the extension but
failed.

Usually, the problem is solved by installing a software package called
"PHP-MySQL" or something similar."

How do I solve this problem???

Is this on a Windows? If so I assume you have installed a version of
PHP 5, because PHP 4 on Windows comes with MySQL support enabled as
default. For PHP 5 you need to check the php.ini file, the
php_mysql.dll extension is _not_ present in the extensions list as
standard and needs adding. If phpMyAdmin can use it (which I suspect
it can) you could also check to ensure the php_mysqli.dll extension
line is un-commented. Save your new ini file, restart Apache and see
what happens.

If you're on a flavour of Unix, wait for someone else to reply to your
message ;)

Best regards,

Richard Davey

Have you tried

round ($value * 100)

?

I want to keep the value of the listbox to submitted value. To do this when
using a text area I use the code

<INPUT NAME="mail_subject" value="<?=$subject; ?>" SIZE="40">

The line

Keeps the value of $subject that was previously entered in the textarea even
after the form is submitted with php_self(). Is this possible with the

Hi,

I used to have problems with this in Cold Fusion - and I'm still
struggling this time in PHP!

Very basic. Looping over 2 tables - an email table, and a data-table.
 I'm using * just for ease for the time being:

SELECT * FROM f_c_users,f_comments WHERE fcEmail=cemail GROUP by fcEmail

If there are more than one records in the data table *per* email, then
I want to group them into one email per user. Instead of sending
10/20/100 emails per person for each record in the data-table. So I
just want to collate everyone's data into one email.

Any thoughts welcome!

Cheers

This isn't a PHP-specific question, it's more a MySQL question. You
might want to try the MySQL mailing lists if you don't get a
satisfactory answer here.

Unless you're using a very recent version of MySQL (4.1+) with the
GROUP_CONCAT function, I'd suggest just looping over the users table and
then looping over the data table separately inside the users loop.
