如何使用Get更新php字段

我找到了。

努力运用我从中学到的东西

<input autocomplete='off' class='loginInput' tabindex='3' type="text" name="company" id="company" value="<?php echo $_GET["entered"]; ?>" maxlength='50' size="25">

JFormField类具有内置的预设和默认选项（这些选项不同，如果字段留空，则默认选项会保存），您可以在表单的XML（文件或字符串）中设置这些选项。API还允许您更改表单的属性或添加新属性。如果使用API，整个代码将更易于编写和阅读。看看核心CMS中的一些示例，您将看到许多示例。
以下几个典型示例显示了添加、设置和获取：

$fieldset->addAttribute('description', 'COM_CATEGORIES_ITEM_ASSOCIATIONS_FIELDSET_DESC');

$field->addAttribute('edit', 'true');
$form->setFieldAttribute('ordering', 'disabled', 'true');
$fieldName = $field->getAttribute('name');

$field
是

，请向我们提供更多信息以帮助您更好地使用。嗨，不是对象。输入字段起作用。我现在尝试从url自动填充字段。url已从上一个表单中输入=（unix时间戳是什么）？输入=1434618105。我正在尝试让1434618105填充该字段。我尝试了，但得到了以下错误：分析错误：语法错误，意外的T_字符串，应为“，”或“；”在第145行的/home/safereco/public_html/test/components/com_safety101/views/actionsitem/tmpl/actionsitem_form.php中，第145行是什么？
<?php echo $field->input; ?>
