The default controller for extension not found.

Some time we get the error like
“The default controller for extension “extname” and plugin “Calendar” can not be determined.
Please check for TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin() in your ext_localconf.php”.

Even we have all the correct configurations in ext_localconf.php and ext_tables.php

This is what we have in ext_localconf.php
\TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin(
‘Vendor.’ . $_EXTKEY,
‘Calendar’,
array(
‘Calendar’ => ‘list, show’,
),
array(
‘Calendar’ => ”,

)
);
?>

This is what we have in ext_tables.php
\TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerPlugin(
$_EXTKEY,
‘Calendar For Dates’,
‘Calendar’
);

All the configurations are perfect but still we get the error, why?

Yes there is the reason for it. Suppose we have more than one extension, or more that one plug in in the same extension.
Other extensions or plugins might have had flexforms, and we have added that plugin and configured the flexform.
Now for the same tt_content element we have selected the plugin “Calendar”, and when we select this plugin we dont see any flexform values of
previous plugins.
But in Databse the table tt_content still stores the flexform values of old plug in and this leades to error.

Solution :
1) Go to databse and delete the flexform values for the perticular tt_content element.
or
2) Delete the old content element and add the new tt_content element.

Color space in Typo3 4.7 with Image magic 6.7.5 or higher

If we are using the tyop3 version 4.7 or less and the Image magic is upgraded to the latest version (>= 6.7.5)
then we need to set the colorspace to sRGB in install tool and need to patch the core file to make it work properly.

Find the file ‘class.t3lib_stdgraphic.php‘ in t3lib.
add the following lines in order

add
protected $IMversion = 0; // ImageMagick Version
after the line
var $nativeCharset = ”; // Is set to the native character set of the input strings.

in similar way

add
else {
$cmd = t3lib_div::imageMagickCommand(‘identify’,’-version | grep Version:’);
$ret = explode(‘ ‘,t3lib_utility_Command::exec($cmd));
$ret = explode(‘.’,str_replace(‘-‘,’.’,$ret[2]));
$this->IMversion = $ret[0].str_pad($ret[1],4,’0′,STR_PAD_LEFT).str_pad($ret[2],4,’0′,STR_PAD_LEFT).str_pad($ret[3],4,’0′,STR_PAD_LEFT);
}
after
if (!$gfxConf[‘im’]) {
$this->NO_IMAGE_MAGICK = 1;
}

Replace the line
$this->cmds[‘jpg’] = $this->cmds[‘jpeg’] = ‘-colorspace RGB -sharpen 50 -quality ‘ . $this->jpegQuality;
after
$this->jpegQuality = t3lib_utility_Math::forceIntegerInRange($gfxConf[‘jpg_quality’], 10, 100, 75);
with
$this->cmds[‘jpg’] = $this->cmds[‘jpeg’] = ‘-colorspace ‘ . ( $this->IMversion >= 6000700050005 ? ‘s’ : ” ) . ‘RGB -sharpen 50 -quality ‘ . $this->jpegQuality;

Replace the line
$this->cmds[‘jpg’] = $this->cmds[‘jpeg’] = ‘-colorspace RGB -quality ‘ . $this->jpegQuality;
after
$this->NO_IM_EFFECTS = 1;
with
$this->cmds[‘jpg’] = $this->cmds[‘jpeg’] = ‘-colorspace ‘ . ( $this->IMversion >= 6000700050005 ? ‘s’ : ” ) . ‘RGB -quality ‘ . $this->jpegQuality;
Replace the line
$this->cmds[‘jpg’] = $this->cmds[‘jpeg’] = ‘-colorspace RGB -quality ‘ . intval($gfxConf[‘jpg_quality’]) . $this->v5_sharpen(10);
after
$this->V5_EFFECTS = 1;
if ($gfxConf[‘im_v5effects’] > 0) {
with
$this->cmds[‘jpg’] = $this->cmds[‘jpeg’] = ‘-colorspace ‘ . ( $this->IMversion >= 6000700050005 ? ‘s’ : ” ) . ‘RGB -quality ‘ . intval($gfxConf[‘jpg_quality’]) . $this->v5_sharpen(10);

TYPO3 fluid selectbox viewhelper.

In the below example, the selectbox options are coming from locallang.

‘hotelclass’ => array(
‘exclude’ => 1,
‘label’ => ‘LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_hotels.hotelclass’,
‘config’ => array(
‘type’ => ‘select’,
‘items’ => array(
array(‘LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_hotels.hotelclass.2star’, ‘2’),
array(‘LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_hotels.hotelclass.3star’, ‘3’),
array(‘LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_hotels.hotelclass.5star’, ‘5’),
array(‘LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_hotels.hotelclass.7star’, ‘7’),
),
‘size’ => 1,
‘maxitems’ => 1,
‘eval’ => ”
),
)

To display this select box in FE from, we can use the custom view helper.

To use the viewhelpler follow the following steps.

1. Create the file

myext/Classes/viewHelpers/TcaOptionsViewHelper.php

2. Add the below code

<?php
namespace TYPO3\Myext\ViewHelpers;

class TcaOptionsViewHelper extends \TYPO3\CMS\Fluid\Core\ViewHelper\AbstractViewHelper {

/**
* local cache for dataMaps
* @var array
*/
protected $dataMaps = array();

/**
* @var \TYPO3\CMS\Extbase\Persistence\Generic\Mapper\DataMapper
* @inject
*/
protected $dataMapper;

/**
* objectManager
*
* @var \TYPO3\CMS\Extbase\Object\ObjectManager
* @inject
*/
protected $objectManager;

/**
* Is returning select values for a property or propertyPath of a given object or className
* @param mixed $subject The object or className the property belongs to
* @param string $property The property itself
* @return array The select options as array
*/
public function render($subject = NULL, $property = ”) {
if (!is_object($subject) && is_string($subject) && class_exists($subject)) {
$subject= $this->objectManager->get($subject);
}
return self::getSelectOptions($property, $subject);
}

/**
* Is resolving the select values for a property or propertyPath of a given object or className
* @param string $propertyPath The property itself
* @param object $subject The object or className the property belongs to
* @return array The select options as array
*/
private function getSelectOptions($propertyPath, $subject) {
$selectOptions = array();

if (is_object($subject)) {
$propertyPathSegments = \TYPO3\CMS\Core\Utility\GeneralUtility::trimExplode(‘.’, $propertyPath);
$object = clone($subject);
$propertyName = $propertyPath;

// resolve a property path
if (count($propertyPathSegments) > 1) {
foreach($propertyPathSegments as $key => $propertyName) {
$propertyType = $this->dataMapper->getType(get_class($tempObject), $propertyName);
if (strpos($propertyType,’_’)) {
$object = $this->objectManager->create($propertyType);
} else {
break;
}
}
}

$dataMap = self::getDataMap($object);

if ($dataMap == NULL || !$dataMap->isPersistableProperty($propertyName)) {
return $selectOptions;
}

$tableName = $this->dataMapper->convertClassNameToTableName(get_class($object));
$columnName = $dataMap->getColumnMap($propertyName)->getColumnName();

// only convert select items which do not have a DB relation
$columnConfig = $GLOBALS[‘TCA’][$tableName][‘columns’][$columnName][‘config’];
if ($columnConfig[‘type’] == ‘select’ && count($columnConfig[‘items’]) && !$columnConfig[‘foreign_table’]) {
foreach ($columnConfig[‘items’] as $option) {
$selectOptions[$option[1]] = \TYPO3\CMS\Extbase\Utility\LocalizationUtility::translate($option[0], $this->controllerContext->getRequest()->getControllerExtensionName());
}
}
}
return $selectOptions;
}

/**
* Resolve the dataMap for the given object
* @param object $object The domain object to get the dataMap for
* @return Tx_Extbase_Persistence_Mapper_DataMap
*/
private function getDataMap($object) {
$class = is_object($object) ? get_class($object) : $object;
if (!isset($this->dataMaps[$class])) {
$this->dataMaps[$class] = $this->dataMapper->getDataMap($class);
}
return $this->dataMaps[$class];
}
}
?>

3. Add the below lines in fluid template, that is intended to show FE form

{namespace custom=TYPO3\Myext\ViewHelpers}

<f:form.select property=”hotelclass” options=”{custom:TcaOptions(property:’hotelclass’,subject:’TYPO3\\Myext\\Domain\\Model\\Hotels’)}” />

4. The output source will be like this.

<select name=”tx_myext_hotels[hotels][hotelclass]”>
<option value=”2″>2 Star</option>
<option value=”3″>3 Star</option>
<option value=”5″>5 Star</option>
<option value=”7″>7 Star</option>
</select>

TYPO3 Extbase call action through ajax.

Below are the steps to call controller action from ajax.

1. Add the following typoscript on extension setup.

plugin.tx_extname {}
#After this
actionname = PAGE
actionname {
typeNum = 1234
config {
disableAllHeaderCode = 1
additionalHeaders = Content-type:application/html|Cache-Control:no-cache, must-revalidate, max-age=0|Pragma:no-cache
xhtml_cleaning = 0
admPanel = 0
}

10 < tt_content.list.20.extname_controllername
}

3. In controller

/**
* action actionname
*
* @return void
*/
public function actionnameAction() {
return ‘test ajax content’;
}

2. In fluid template

<f:link.action action=”actionname” additionalParams=”{type:’1234′,no_cache:’1′}” noCacheHash=”1″ class=”test”>
Ajax click
</f:link.action>
<div id=”ajax_content”></div>
<script type=”text/javascript”>
$(document).ready(function(){
$(‘.test’).click(function() {
var href = $(this).attr(‘href’);
$.ajax({
url: href,
cache: false,
success: function(htmldata){
$(“#ajax_content”).html(htmldata);
}
});
return false;
});
});
</script>

If everything is correct, it should work.
