我可以在模块构建中检查什么以确保drupal中没有崩溃

我有一个简短的问题，我目前正在运行Drupal的一个测试站点。我有一个为6.16版本之前的测试站点编写和支持的模块，我当前希望在启用该模块时在崩溃中使用该模块

我想知道我可以查看哪些基本元素来确保代码兼容，或者是否需要更改

此模块提供了CRM与Drupal for SSO的集成

我想，如果其他人遇到创建模块来弥合系统之间的差距，他们可能会为我指明正确的方向

这是我启用模块时收到的错误：

Parse error: syntax error, unexpected T_OBJECT_OPERATOR in /homepages/22/d223624283/htdocs/drupal6/sites/all/modules/convio/convio.module on line 104

这是名为convio.module的文件中的代码，它给了我一个问题：

新评论后更新：

您是否仍在使用PHP4？这可以解释错误-方法链接（意味着直接在应该返回对象的函数上使用“->”运算符）仅在PHP 5 IIRC中支持

如果是这样，正确的解决方案是切换到PHP5

作为临时解决方案，您可以搜索直接在函数/方法结果上使用'->'运算符的所有位置（

functionCall（）->…

），并通过另一个变量插入分隔符请注意，我不建议这样做-PHP 4已弃用，不再接收安全更新。在it上运行生产环境是一个大问题

---

原始答案：

该代码中唯一的

T_OBJECT_运算符
（'->'）似乎位于：

if (ConvioConfiguration::getInstance()->isEnabled()) { ...

因此，您可能希望将该行更改为以下内容：

$convioConfiguration = ConvioConfiguration::getInstance();
if (is_object($convioConfiguration) && $convioConfiguration->isEnabled()) { ...

嗯，这是convio.module
第104行的语法错误-您应该在问题中添加该行（以及周围环境，如果不太长，可能是整个函数），因为它可能很容易修复。@Henrik Opel感谢您的回答。。。我现在要补充一点。第104行到底是什么，您是否在104之前包含了一些行，问题也可能出现在哪里？或者，你可以将整个文件粘贴到@googletorp之类的东西中。。。我不熟悉这个drupal.pastebin.com，这是一个帮助更正代码的开发人员社区吗？我非常乐意包含这个模块的所有文件，如果这意味着我可以让它与6.19版及更高版本一起使用：）我现在就试试，然后再给你回复。@Matthew:看起来你还在使用PHP4-我相应地更新了我的答案。。。我将运行PHP5，看看会发生什么。
