DISCLAIMER: use at your own risk!!
This is not optimal performance wise, since to use it, one should disable
viewcaching in your settings.
Quick installation instructions:
1) If it not exists, create the folder "extension/kernel/common" in the
base ezpublish directory
2) put the file "templateezenvoperator.php" in
"extension/kernel/common"
3) If you have already a file "eztemplateautoload.php" in
"extension/kernel/common",add the following lines
$eZTemplateOperatorArray[] = array( 'script' =>
'extension/kernel/common/templateezenvoperator.php',
'class' => 'TemplateEzenvOperator',
'operator_names' => array( 'ezenv' ) );
If you do not have this file, copy "eztemplateautoload.php" from the
zip archive there
4) Make sure you have the settings from in your
settings/override/site.ini.append[.php] for the AutoloadPath in
[TemplateSettings]
eg,:
AutoloadPath=lib/eztemplate/classes/;kernel/common/;extension/kernel/common/
Note: do not put spaces between the semicolons
Also DISABLE View aching in the [ContentSettings]:
ViewCaching=disabled
5) Clear the caches (including the ini caches)
6) Now you can define additional variables (form elements) in your
templates, for example:
.....




.....
My field contains: {"myfield"|ezenv|wash}
.....
7) You can also use GET style variables (append them to the current
URL)
8) Be careful not to nest constructs, especially for the
admin templates or user-side edit templates
9) As allways: Clear your caches before trying your edited
templates
PS: apparently, you do not have to define these as "ActiveExtensions"
(which is the case with full modules)
Enjoy!
