i有一个控制器方法，该方法可以检查发布数据并通过form_validation Run方法解析此方法。我的视图中还有一个图像上传字段，可以上传图像。问题在于，当文件上传太大的文件时，假设超过10MB时，表单验证将返回我的验证规则中定义的每个错误。如果我上传一个仍然太大但不是太多的文件，我会收到正确的错误消息。
我的代码看起来像这样：

请注意，当我上传19 MB的图像时，出于某种原因，我最终在底部的其他条款中列入了Else子句，并且我得到了一个页面，显示了所有验证错误，上面写着："，" Naam是Verplicht"，……所有人都从字面上看。所有数据都正确填写，当我执行完全相同的步骤时，但以小于3MB的映像，它的工作原理。
SO 0-3MB-完美工作。3-10MB-给出完美的错误> 10 MB-给出所有验证错误。

我弄清楚php.ini中的post_max_size设置为8MB，这导致$ _ post变量变为null ...设置一个情况下，如果情况下，请检查$ _post是否未解决$ _post问题！谢谢
