[英]Using codeigniter to update multiple rows
I am trying to update multiple rows at a time in codeigniter. 我试图一次在Codeigniter中更新多行。 I have the following a an example of the fields I need to update for each user
以下是我需要为每个用户更新的字段的示例
<div class="row">
<input type="text" name="id[46][firstname]" value="">
<input type="text" name="id[46][lastname]" value="">
</div>
<div class="row">
<input type="text" name="id[48][firstname]" value="">
<input type="text" name="id[48][lastname]" value="">
</div>
I am struggling to grab the values for update. 我正在努力获取要更新的值。 The actual update statement shouldn't be a problem, I'm just concerned with retrieving the correct form values per user.
实际的更新语句应该不是问题,我只关心与每个用户检索正确的表单值。
foreach($_POST as $key => $value){
$keyparts = explode('_', $key);
if(count($keyparts) == 2){
switch ($keyparts[0]) {
case 'firstname':
$records[$keyparts[1]]->firstname = $value;
break;
case 'lastname':
$records[$keyparts[1]]->lastname = $value;
break;
default:
break;
}
}
// update statement to go here
}
HTML Code HTML代码
<div class="row">
<input type="text" name="46[firstname]" value="">
<input type="text" name="46[lastname]" value="">
</div>
<div class="row">
<input type="text" name="48[firstname]" value="">
<input type="text" name="48[lastname]" value="">
</div>
PHP Code PHP代码
$records = array();
foreach($_POST as $key => $value){
if(is_array($value))
{
foreach($value as $new_key=>$new_val)
{
$records[$key][$new_key] = $new_val;
}
}
}
The problem is that you are not understanding how your POST is building the array. 问题是您不了解POST如何构建阵列。 From you HTML above, the form will build the following POST array:
通过上面的HTML,表单将构建以下POST数组:
array =>
[id] =>
[46] =>
[firstname] => "john"
[lastname] => "doe"
[48] =>
[firstname] => "jane"
[lastname] => "doet"
with the array being visually laid out like that, you can now iterate, to obtain your values. 像这样在视觉上布置数组,现在可以迭代以获得值。 However, one thing I do not understand in your code, is why you are using
explode()
, what are you trying to turn into an array? 但是,我在您的代码
explode()
不懂的一件事是,为什么要使用explode()
,您打算将什么变成数组? You can easily iterate and update this information in your database like so: 您可以轻松地在数据库中迭代和更新此信息,如下所示:
$this->load->model("my_model");
$postdata = $this->input->post();
foreach($postdata['id'] as $id => $user_info){
$this->my_model->update_user($id, $user_info); // your model method should handle the update information by ID.
}
if you do echo "<pre>" .print_r($_POST, true)."</pre>";
如果您确实
echo "<pre>" .print_r($_POST, true)."</pre>";
on the form processing page, the result should look linke this 在表单处理页面上,结果应如下所示
Array
(
[id] => Array
(
[46] => Array
(
[firstname] => firstNameValue1
[lastname] => lastNameValue1
)
[48] => Array
(
[firstname] => firstNameValue2
[lastname] => lastNameValue2
)
)
)
So, this should help you catch the values: 因此,这应该可以帮助您捕获值:
foreach($_POST['id'] as $key => $value){
$records[$key] = (object)array();
$records[$key]->firstname = $value['firstname'];
$records[$key]->lastname = $value['lastname'];
// update statement to go here
}
Results this structure: 结果该结构:
Array
(
[46] => stdClass Object
(
[firstname] => firstNameValue1
[lastname] => lastNameValue1
)
[48] => stdClass Object
(
[firstname] => firstNameValue2
[lastname] => lastNameValue2
)
)
