从控制器中的FlexForms获取TYPO3插件设置

Question

I have a FE Plugin which uses a FlexForm MyExtFlexForm which is used to set certain configurations like limit or SourcePage etc..

In my controller action list I get these settings using $this->settings. Works fine till now.

Now, I make AJAX calls to action update and I need to use the same settings which have been set earlier through the FlexForm for the FE plugin on this page. $this->settings does not show anything.

I checked $GLOBALS['TSFE']->tmpl->setup['plugin']['MyExt.']['settings.'] and none of the settings defined in FlexForm show here.

How do I solve this issue?

EDIT:

My sample Flexform looks like this:

<sheets>
        <sDEF>
            <ROOT>
                <TCEforms>
                    <sheetTitle>View Settings</sheetTitle>
                </TCEforms>
                <type>array</type>
                <el>
                    <switchableControllerActions>
                        <TCEforms>
                            <label>Select</label>
                            <config>
                                <type>select</type>
                                <items>
                                    <numIndex index="0">
                                        <numIndex index="0">MyFunction</numIndex>
                                        <numIndex index="1">MyExt->list</numIndex>
                                    </numIndex>
                                </items>
                            </config>
                        </TCEforms>
                    </switchableControllerActions>

                    <settings.flexform.limit>
                        <TCEforms>
                            <label>Number of items to be displayed</label>
                            <config>
                                <type>input</type>
                                <size>10</size>
                            </config>
                        </TCEforms>
                    </settings.flexform.limit>
                </el>
            </ROOT>
        </sDEF>
    </sheets>

Then I make an AJAX call to my controller action and print this $this->settings , shows no settings.

The easiest solution is proper naming fields in FlexForm ie, if your field will be prefixed with settings. it will be visible in $this->settings array:

<settings.myField>
    <TCEforms>
        <label>My very special setting</label>
        <config>
            <type>input</type>
        </config>
    </TCEforms>
</settings.myField>

Controller:

$mySetting = $this->settings['myField'];

On the other hand if you're planning to merge TS settings with FlexForm settings you can prefix it additionaly with some other word like: <settings.flexform.myField> and then access it:

$fromTypoScript = $this->settings['myField'];
$fromFlexform   = $this->settings['flexform']['myField'];

// or...
$myMergedSetting = (!$this->settings['flexform']['myField'])
                   ? $this->settings['myField']
                   : $this->settings['flexform']['myField'];
