Tag Pack

Having had no answer, I'm coming up with a proposal. The attached patch enables the following syntax (for example to override the tag selector for the "pages" table):

$TCA['tx_tagpack_tags']['tagpack_options']['alternateTCA']['pages'] = array(...);

The array contains a TCA-column configuration. Note that the syntax itself is not standard TCA, but that causes no disturbance. I thought about using TYPO3_CONF_VARS first, but this causes problems with the loading order of the temp_CACHED_* files.

The attached patch changes class tx_tagpack_tceforms_addtags to make it aware of such configurations. It will first check for $TCA['tx_tagpack_tags']['tagpack_options']['alternateTCA']['*tablename*'] to override the settings for a specific table. It then checks for $TCA['tx_tagpack_tags']['tagpack_options']['alternateTCA']['*default*'] that will override settings for all tables. If none of these are found, it moves on to the normal field setup (group-type with wizard).

What do you think? I find it really useful to be able to have a different rendering for the tags selector in special cases (and indeed I have a client request for that).

For information I finished a first working version of my extension that would introduce a custom screen. You can find it at:

https://svn.typo3.org/TYPO3v4/Extensions/tagpack_altselector/trunk

if you want to test this issue. Attached a screenshot to give you an impression.

OK, moving ahead with the T3_VAR proposal.

Here's an updated version of my patch, using T3_VAR instead of the originally proposed pseudo-TCA.

Extension tagpack_altselector has been updated accordingly. For proper testing note that:

- the alternate tag selector is defined only for the pages table
- it expects tags to have categories. So if you have none, you'll probably end up with a very long list of checkboxes.

Thanks for the green light!

Committed to trunk in revision 27469.

Here's a short documentation for the record:

To override the default TCA configuration for the tag selection field, you can store an alternate TCA configuration in the global T3_VAR array. The full path is $T3_VAR['EXT']['tagpack']['TCA']['alternate_config'][table_name]. If tagpack detects such a configuration, it will use it instead of the default one for the given table.

It's also possible to define the path as $T3_VAR['EXT']['tagpack']['TCA']['alternate_config']['default'] which will override the default configuration for all tables.

Example taken from the tagpack_altselector extension (file ext_tables.php), which overrides the configuration for the "pages" table:

    // Include class for custom field
require_once(t3lib_extMgm::extPath('tagpack_altselector', 'class.tx_tagpackaltselector_tceforms.php'));

    // Define alternate TCA configuration for tag selector
$alternateConfiguration = array(
                                'label' => $TCA['tx_tagpack_tags']['ctrl']['title'],
                                'exclude' => 0,
                                'config' => array(
                                    'type' => 'user',
                                    'userFunc' => 'tx_tagpackaltselector_TCEForms->selectorField',
                                )
                            );

    // Set the alternate configuration for the pages table
$T3_VAR['EXT']['tagpack']['TCA']['alternate_config']['pages'] = $alternateConfiguration;

I'm reopening this issue, because my commit was actually overridden in r30104 when trunk way synchronized with TER version.

May I re-commit my patch to trunk?

And of course, the usual question: any release planned in the near future?
