[Fabietto89]

salve ragazzi, nel seguente codice ho questo tipo di errore..

        <?
        if($key == 'lang'){
                  echo "<select class=\"form-control\" name='lang'>";
                  $all_files=array();
                GetListFiles(dirname(__DIR__)."/lang",$all_files);
                foreach($all_files as $value){
                    $a = explode("/",$value);
                    $a1 = end($a);
                    $a2 = explode(".",$a1);
                    echo "<option value='".current($a2)."'";
                    if(current($a2) == $SET['lang']){
                        echo ' selected="selected"';
                    }
                    echo ">".current($a2)."</option>";
                }
                echo "</select>";
         }elseif(!in_array($key,array('ads_468x60','ads_250','ads_728x90','google_analytics'))){?>
          <input type="text" class="form-control input-lg" id="<?php echo $key?>" name="<?php echo ucfirst(str_replace("_"," ",$key))?>" <?php if($key == 'version'){?> disabled="disabled"<?php }?> value="<?php echo htmlspecialchars(stripcslashes($val))?>">
          <?php }else{?>
          <textarea class="form-control" id="<?php echo $key?>" name="<?php echo $key?>" rows="5"><?php echo htmlspecialchars(stripcslashes($val))?></textarea>
          <?php }?>
        </div>
     </div>
     <?php }else{
            foreach($val as $k=>$v){?>
            <div class="form-group">
                <label for="<?php echo $k?>" class="col-md-3 control-label">Social btn "<?php echo ucfirst(str_replace("_"," ",$k))?>"</label>
                <div class="col-md-9">
                  <input type="text" class="form-control" id="<?php echo $k?>" name="social[<?php echo $key?>][]" value="<?php echo htmlspecialchars($v)?>">
                </div>
             </div>
<?php            }?>
    <?php }?>
<?php }?>

la riga dell'errore è quella segnalata in rosso.. avete idea di come risolvere questo errore?!

grazie
