文件扩展JFormField

Question

我有一个名为iconbasic的文件中的代码应该运行我的个人资料图片上传器，但它不工作。任何人有任何想法为什么？

我新的这一点，但是，在组件弗朗端的agentform文件夹中有哪些具有此行成为一个edit.php文件：

<?php echo $this->form->getInput('icon'); ?> 

然后在模型文件夹中，我们有代理.xml文件，它使用此行主要指这在iconbasic.php：

<field name="icon" type="iconbasic" label="COM_IPROPERTY_IMAGE" readonly="true" folder="agents" /> 

然后在组件的档案管理员，我有一个在里面的子文件夹名为领域模型文件夹名为iconbasic.php文件。 在前端，该网站允许我上传文件，然后我发现它们存储在正确的目录中，但它们不显示在网站上。我试图找出为什么，并会真正感谢一些帮助的原因。没有编码经验，使用记事本自己今天++刚刚或多或少想通了这一点:)

这是iconbasic.php文件：
