[TYPO3-dev] Update database when saving plugin flexform configuration in BE?

[Gerhard Mehsel]

Hello,

I have a plugin which is configurable through flexform. I configure some 
values and press the save-button. In this moment I need to update a 
special table in the TYPO3 database. This is because an external 
webservice must read the configured values from the flexform.

While it is an external webservice which has no relation to TYPO3 I 
don't have the chance to access flexform values with
$this->pi_initPIflexForm();
$this->pi_getFFvalue($this->cObj->data['pi_flexform'], "val", "sheet");



I tried to achieve this with a <itemsProcFunc> class which updates the 
database but the problem is, that the <itemsProcFunc> is called before 
or while rendering the flexform and not afterwards.

itemsProcFunc -> render flexform -> configure value -> SAVE button -> 
itemsProcFunc -> render flexform

Database updated because of the second call to itemsProcFunc after 
saving the plugin. Ok.

But this way:
itemsProcFunc -> render flexform -> configure value -> SAVE-AND-CLOSE button

Database NOT updated because there is no second call to itemsProcFunc.


How can I do this?

Regards,
Gerd
