在我的项目中使用 Phalcon 的 Volt 引擎时出现奇怪的 PHP 错误。这个案例似乎很简单，但是虽然我已经检查了很多次我的代码，但我似乎无法使用简单的 if-elseif-endif 结构。

模板代码在这里，它被放置在 jQuery callcack 函数上下文中的 Javascript 块中：

{% if table.form.rendered_in == 'offcanvas' %}
            //offcanvas form
            //set attributes

            $(row).find('td.edit-control').

                attr('data-source', '{{table.form.full_action_url}}?get_form').
                attr('data-canvas', 'body').
                attr('data-target', '#rightSlider').
                attr('data-toggle', 'offcanvas').

                click(function () { 
                    console.log('! show edit form: '+record_id);    
                    //edit_one(record_id);
                    if (!right_offcanvas_visible) {

                        //request form with ajax
                        var url = $(this).attr('data-source');
                        var data = {
                            'choose_record': [record_id]
                        };

                        //console.log('Serialized data: '+data);

                            //$('div.offcanvas').offcanvas({canvas: 'body'}); // todo: make it work!
                            console.log('! edit one record form set up');    
                        });

                    }

                });

            $(row).find('td.delete-control').

        {% endif %}

该错误可能是由 Volt 编译器首先在下面引用的 elseif 生成的，volt 文件没有被编译到 PHP 中。

{% elseif table.form.rendered_in == 'page' %}

错误说： 第 307 行的 .../app/views/partials/grideditor.volt 中出现意外的 ENDIF

if-elseif-endif 结构在 Javascript 块的其他地方也能很好地工作。更奇怪的是，当我用多个 if-endif、if-endif、... 替换 elseif 时，一切正常。

我在 Windows 上使用 Phalcon 1.3.3 TS（x86，PHP 5.4.19）

任何建议都非常感谢！谢谢！

您可以在 volt 中启动 php 并做那些 volt 不提供的事情。

我相信未来我们会有

{% literal %} {% endliteral %} 
or
{% verbatim %} {% endverbatim %}

github中已经有NFR：https ://github.com/phalcon/cphalcon/issues/1253

现在我找不到任何出路，只是在这部分使用纯 php，例如：

...
<?php
 // your code like it would be simple *.php file
?>
...
