Viel danke für deine bemüht um du mir zu helfe!

Wie deine Code jetzt ich habe,

[{php}]
 $hallo = array('205001', '205001-1', '205001-2', '205001-3');
 $this->assign(“hallo”, $hallo);
[{/php}]
[{if (in_array($oDetailsProduct->oxarticles__oxartnum->value, $hallo))}]
[{block name="lokta_schreibe"}]
 [{oxhasrights ident="SHOWLONGDESCRIPTION"}]
   [{oxifcontent ident="9d19a20335d164d004f26292759245b9" object="oCont"}]
     [{assign var="hope" value=$oCont->oxcontents__oxcontent->value}]
     [{if $oCont->oxcontents__oxtitle->value}]
        [{capture append="tabs"}]<a class="nav-link[{if $blFirstTab}] active[{/if}]" href="#joseba" data-toggle="tab">[{$oCont->oxcontents__oxtitle->value}]</a>[{/capture}]    
         [{capture append="tabsContent"}]
           <div id="joseba" class="tab-pane[{if $blFirstTab}] active[{/if}]" itemprop="joseba">
             [{oxeval var=$hope }]
             [{if $oDetailsProduct->oxarticles__oxexturl->value}]
                <a id="productExturl" class="js-external" href="[{$oDetailsProduct->oxarticles__oxexturl->value}]">
                [{if $oDetailsProduct->oxarticles__oxurldesc->value}]
                    [{$oDetailsProduct->oxarticles__oxurldesc->value}]
                [{else}]
                    [{$oDetailsProduct->oxarticles__oxexturl->value}]
                [{/if}]
                </a>
             [{/if}]
           </div>
      [{/capture}]
	  [{assign var="blFirstTab" value=false}]
   [{/if}]
  [{/oxifcontent}]
[{/oxhasrights}]
[{/block}]
[{/if}]

aber bekommt dieser warnung,

Warning : in_array() expects parameter 2 to be array, null given in /var/www/html/oxid/source/tmp/smarty/147c42bfd77af53c89df35f918f06a4d^%%F5^F50^F500F10E%%tabs.tpl.php on line 42

Auf der Zeile 42 habe [{oxeval var=$hope }]
