对不起老兄，这是我的第一个问题，我一直在你的网站上住了一段时间并且学到了很多东西，但现在我有一个问题，我找不到答案，问题是我有一个填写两个不同视图的表单，一个用于选择将在第二个视图上编辑的课程，第二个应该已经填充了在数据库上等于它们的所有字段，我知道应该完成设置默认值使用set_value函数定义第二个参数，但它不起作用，其他一切似乎都很好......
这是我的第一个观点
<?php echo link_tag('assets/css/nuevocurso.css');?>
<div id="infoMessage"><?php echo $message ?></div>
<section class="container">
<div class="register">
<h1>Ingrese el código del curso que desea modificar.</h1>
<?php echo form_open("curso/modificarcurso");?>
<p> <i>Código</i> <br /> <?php echo form_input($codigo);?> </p>
<p class="submit"><?php echo form_submit('commit', "Registrarse");?></p>
<?php echo form_close();?>
</div>
</section>
<br/>
这是我的第二个观点
<?php echo link_tag('assets/css/nuevocurso.css');?>
<div id="infoMessage"><?php echo $message ?></div>
<section class="container">
<div class="register">
<h1>Modifique los atributos de curso que desee.</h1>
<?php echo form_open("curso/gestionarcurso");?>
<p> <i>Nombre</i> <br /> <?php echo form_input($nombre);?> </p>
<p> <i>Descripcion</i> <br /> <?php echo form_textarea($descripcion);?> </p>
<p> <i>Codigo</i> <br /> <?php echo form_input($codigo);?> </p>
<p> <i>Alias</i> <br /> <?php echo form_input($alias);?> </p>
<p> <i>Programa</i> <br /> <?php echo form_textarea($programa);?> </p>
<p class="submit"><?php echo form_submit('commit', "Registrarse");?></p>
<?php echo form_close();?>
</div>
</section>
<br/>
和我的控制者

$this->load->view('home/header_view');
$this->load->view('curso/gestionarcurso',$this->data);

}
}
set_value位于控制器上名为manage的最后一个函数中，那些不起作用，不用担心模型，我还没有使用存储在其中的唯一函数。
谢谢大家，stackoverflow太神奇了！

如果要设置值，CodeIgniter表单助手需要两个参数，例如：
echo form_input('nombre', $nombre);
正如手册所说：“你可以在第一个和第二个参数中最低限度地传递字段名称和值”

它会在您的视图中如下工作：
echo form_input(array('name' => 'codigo', 'id' => 'codigo'), set_value('codigo', 'YOUR_VALUE'));
