[TYPO3-dev] meet a problem when using a HTML template‏

[lm x]

Hello Everyone:

I'm just writing my first ext with a HTML template.  In the template there are two parts. The first part(###LISTVIEW###) has a form. when I submit the form, it shoud show me the second part(###DETAILVIEW###).

However it doesn't show the second part. and still show the first.  please Anyboby tell me what's wrong in my code. thank you!!!


the PHP part:

<?php

require_once(PATH_tslib.'class.tslib_pibase.php');

class tx_modulbuchtest_pi1 extends tslib_pibase {
    var $prefixId = 'tx_modulbuchtest_pi1';        // Same as class name
    var $scriptRelPath = 'pi1/class.tx_modulbuchtest_pi1.php';    // Path to this script relative to the extension dir.
    var $extKey = 'modulbuch_test';    // The extension key.
    var $pi_checkCHash = TRUE;

    function main($content,$conf)    {
        $this->conf=$conf;
        $this->pi_setPiVarDefaults();
        $this->pi_loadLL();
        
        #ein paar Vorbelegungen
        $this->id=$GLOBALS['TSFE']->id;
        $this->template=$this->cObj->fileResource('EXT:modulbuch_test/template.html');
        
        #welche Ansicht?
        if($this->piVars['item']) {
            $content = $this->detailView();
        } else {
            $content = $this->listView();
        }
    
        return $this->pi_wrapInBaseClass($content);
    }
    
    function listView() {
        $subpart=$this->cObj->getSubpart($this->template,'###LISTVIEW###'); 
        $singlerow=$this->cObj->getSubpart($subpart,'###ROW###'); 
        
        $markerArray['###ACTION_URI###'] = htmlspecialchars($this->pi_getPageLink($GLOBALS["TSFE"]->id));
    
        $res=$GLOBALS['TYPO3_DB']->exec_SELECTquery(
        '*',   #select
        'tx_modulbuchtest_module', #from 
        'hidden=0 and deleted=0 and pid='.$this->id,  #where
        $groupBy='',
        $orderBy='',
        $limit='');
        
        if($res) {
            $liste='';
            while($row=$GLOBALS['TYPO3_DB']->sql_fetch_assoc($res)) 
            {
                $markerArray['###PROTYPE###']='<option value="456">'.$row['sprache'].'</option>';
                $liste .= $this->cObj->substituteMarkerArrayCached($singlerow,$markerArray); 
            }
            
            $subpartArray['###ROW###']=$liste;
        } else {
            return $this->pi_getLL('nodata');
        }
        
        return $this->cObj->substituteMarkerArrayCached($subpart,$markerArray,$subpartArray,'');  
    }
    
    
    
    function detailView() {
         $subpart=$this->cObj->getSubpart($this->template,'###DETAILVIEW###'); 
       
         $markerArray['###VORNAME###']='content for firstname';
            
        return $this->cObj->substituteMarkerArrayCached($subpart,$markerArray,'','');
    }
    
}  
 

if
(defined('TYPO3_MODE') &&
$TYPO3_CONF_VARS[TYPO3_MODE]['XCLASS']['ext/modulbuch_test/pi1/class.tx_modulbuchtest_pi1.php'])  
 {
    include_once($TYPO3_CONF_VARS[TYPO3_MODE]['XCLASS']['ext/modulbuch_test/pi1/class.tx_modulbuchtest_pi1.php']);
}

?>
