php - 扩展 JFormField 的文件

Question

我在一个名为 iconbasic 的文件中有此代码，该文件应该运行我的个人资料图片上传器，但它不工作。有人知道为什么吗？

我是新手，但是，组件前端的 agentform 文件夹有一个 edit.php 文件，其中包含以下行：

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

然后在模型文件夹中，我们有 agent.xml 文件，它基本上使用以下行将其指向 iconbasic.php：

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

然后在组件的管理员文件中，我在名为 fields 的子文件夹内的模型文件夹中有一个名为 iconbasic.php 的文件。在前端，该站点允许我上传文件，然后我发现它们存储在正确的目录中，但它们没有显示在站点上。我正在尝试找出原因，并且非常感谢您的帮助。没有编码经验，今天自己使用记事本++或多或少地弄清楚了这一点:)

这是 iconbasic.php 文件：
