Question

我找到了。 HTML - How to pre-populate form field with known value upon load?

并尝试应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">

到下面的一段代码（来自我正在构建的J-Cook组件）

<?php
// incident
$field = $fieldSet['jform_incident'] ;

?>
<div class="control-group <?php echo 'field-' . $field->id . $field->responsive; ?>">
    <div class="control-label">
        <?php echo $field->label; ?>
    </div>

    <div class="controls">

        <?php echo $field->input; ?>

假设代码与上面的示例不同，我尝试了多种方法使表单自动填充

<?php echo $field->input; ?>

运气好的话。如果有人能帮助我，我真的很感激。我现在完全失去了？：（

Answer 1

JFormField类具有内置的预设和默认选项（这些是不同的，默认情况下，如果您的字段留空，则会保存），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，整个代码将更容易编写和读取。看一下核心CMS中的一些示例，您将看到许多示例。以下是一些典型示例，显示了add，set和get：

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

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