尝试以twig格式格式化该代码:
<textarea class="form-control" name="email_review_subject_<?php echo $language['language_id']; ?>" ><?php echo isset(${'email_review_subject_' . $language['language_id']}) ? ${'email_review_subject_' . $language['language_id']} : ''; ?></textarea>
所以我尝试了这种格式:
<textarea class="form-control" name="email_review_subject_{{ language['language_id'] }}" >{{ isset({'email_review_subject_' . language.language_id}) ? {'email_review_subject_' . language.language_id} : '' }}</textarea>
错误:

我很确定你不能使用.
来连接Twig中的字符串。试试~
,然后查看:How to concatenate strings in twig

isset
中没有twig
这样的内容。如果要在树枝中使用动态变量
_context
一些可能的解决方案,
<textarea class="form-control" name="email_review_subject_{{ language['language_id'] }}" >{{ attribute(_context, 'email_review_subject_'~language.language_id)|default('') }}</textarea>
<textarea class="form-control" name="email_review_subject_{{ language['language_id'] }}" >{{ attribute(_context, 'email_review_subject_'~language.language_id) is defined ? attribute(_context, 'email_review_subject_'~language.language_id) : '' }}</textarea>
