Question

我是joomla的新手。我遇到了一个问题，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，我想使用用户输入来输入自己的值。例如，如果用户在文本字段name中输入并且用户输入他的名字John，那么我想在netnock之后通过后端添加John。
这是Joomla表格

        <?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>

假设您在组件中遵循joomla准则和体系结构，则可以在模型save（）或prepareTable（）函数或表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);
}
