我在这个网站和网上广泛地查看了这个问题的答案。我试图将一些示例应用于我的问题,但无济于事。
我有两个块,名为“ Links
”和“ User Links
”。在每个块内,它们是我网站上链接的描述(它们本身就是块),可以从左到右单独拖动。
我的问题是一旦我按下“ Save Changes
”,我就无法将数据保存到我的数据库中,我的错误是“ Undefined index: quicklink
”
这是代码。
<?php echo Form::open(URL::Base().Route::get('links')->uri(array('action' => 'update')), array('id' => 'links-form', 'class' => 'form', 'enctype' => 'multipart/form-data')) ?>
<section class="grid_12">
<div class="block-border">
<div class="block-content">
<div class="block-controls">
<div class="controls-buttons"></div>
</div>
<h1>Quick Links</h1>
<div class="columns">
<div class="colx2-left">
<fieldset>
<legend>Links</legend>
<p class="inline-small-label small-margin">
<div class="column">
<?php if (count($links)): ?>
<?php foreach ($links as $row): ?>

控制器
/**
* Update the Users settings and details
*
* @return void
*/
public function action_update()
{
$this->template = NULL;
$this->auto_render = FALSE;
if ($_POST)
{
$row = ORM::factory('LinkUser');
// Remove all current Links
foreach($row->link->find_all() as $ql)
$row->remove('link', $ql);
foreach($_POST['link'] as $ql)
{
$row->add('link', $ql);
}
}
}
模型“链接”
<?php defined('SYSPATH') or die('No direct access allowed.');
class Model_Link extends ORM {
protected $_table_name = 'links';
protected $_has_many = array(
'qlinkusers' => array(
'model' => 'LinkUser',
'foreign_key' => 'link_id',
'through' => 'links_users',
),
);
}
模型“链接用户”
<?php defined('SYSPATH') or die('No direct access allowed.');
class Model_LinkUser extends ORM {
protected $_table_name = 'links_users';
protected $_belongs_to = array(
'link' => array(
'model' => 'Link',
'foreign_key' => 'link_id',
'through' => 'links_users',
),
'user' => array(
'model' => 'user',
'foreign_key' => 'user_id',
),
);
}
我对jQuery非常弱,希望很清楚我需要什么......我想将一些链接从左侧块拖到右侧块,到目前为止这是成功的,我无法将数据保存到我的数据库中一旦我按下“ Save Changes
”,我的错误是“ Undefined index: link
”
非常感谢。
