如何更改Joomla表单值?

Question

我是joomla的新手。我一直面临一个问题，我想更改Joomla表单值，例如，当用户在表单字段中输入任何内容时，我想通过用户输入输入自己的值。即如果用户输入文本字段name并且用户输入他的名字 John，那么我想在通过后端John后添加netnock。
这是Joomla形式

<?xml version="1.0" encoding="utf-8"?>
<form>
<fieldset>
<field
name="id"
type="hidden"
/>
<field
name="name" <!-- I want to add my values to this field -->
type="text"
label="Enter Name:"
description="COM_FORMMANAGER_FORMMANAGER_NAME_DESC"
size="40"
class="inputbox"
default=""
/>
</fieldset>
<field name="types" type="list" default="" label="Select Field Types:" description="">
<option value="text">text</option>
<option value="email">email</option>
<option value="password">password</option>
<option value="textarea">textarea</option>
</field>
</form>

这是模型

if (empty($form))
{
return false;
}
return $form;
}

$data = JFactory::getApplication()->getUserState(

array()
);
if (empty($data))
{
$data = $this->getItem();
}
return $data;
}
}

假设你在组件中遵循joomla指南和架构，你可以在模型save((或prepareTable((函数中，或者在table check((或store((函数中做到这一点。

例如

public function save($data)
{
$data['name'] .= ' Bond, my name is Bond';
return parent::save($data);
}
