当我尝试使用for循环更新细节时，它会更新为空（Null）以引用列。
以下是我的代码，请帮助我解释我的逻辑错误。
查看代码
将生成的文本字段数取决于否。表中列出的值它正在foreach循环中执行
<form method="post" action="<?php echo site_url('Home/advisor_update'); ?>"
<?php
if ($advisor_emp->num_rows()>0 )
{
$i=1;
foreach($advisor_emp->result() as $data)
{
$eid = $data->id;
$cn = $data->company_name;
$fd = $data->from_date;
$td = $data->to_date;

}
?>

这是我的控制器
在控制器中，我将使用for循环从视图中获取数据并将收到的数据发送到模态。
if ($this->input->post('advisor_update'))
{
$emp_his_id = $this->input->post('eid');
$count_eid = count($emp_his_id);
for($i=0;$i<$count_eid;$i++)
{
$emp_his_pk = $emp_his_id[$i];
$inserte['company_name']= $this->input->post('cn');
$inserte['from_date']= $this->input->post('fd');
$inserte['to_date']= $this->input->post('td');
$inserte['type_of_buisness']= $this->input->post('tb');
$inserte['company_addres_lane_1']= $this->input->post('c1');
$inserte['company_addres_lane_2']= $this->input->post('c2');
$inserte['c_city']= $this->input->post('cc');
$inserte['c_pincode']= $this->input->post('cp');
$inserte['updated_on'] = date("Y-m-d");
$up_emp_history=$this->Frontend_model->update_employe($inserte=array(),$emp_his_pk);
}
}
这是我的模态
function update_employe($inserte=array(),$emp_his_pk)
{
$this->db->where('id',$emp_his_pk);
$result=$this->db->update("is_employment", $inserte);
return $result;
}

我已更改您的视图代码输入名称
<form method="post" action="<?php echo site_url('Home/advisor_update'); ?>" >
<?php
if ($advisor_emp->num_rows()>0 )
{
foreach($advisor_emp->result() as $data)
{
$eid = $data->id;
$cn = $data->company_name;

$td = $data->to_date;
$tb = $data->type_of_buisness;
$c1 = $data->company_addres_lane_1;
$c2 = $data->company_addres_lane_2;
$cc = $data->c_city;
$cp = $data->c_pincode;
$cs = $data->c_state;
$cun = $data->c_country; ?>
<div class="col-md-6">

你必须在控制器中运行一个foreach循环。
if ($this->input->post('advisor_update'))
{
$emp_his_id = $this->input->post('eid');
$cn = $this->input->post('cn');
$fd = $this->input->post('fd');
$td = $this->input->post('td');
$td = $this->input->post('tb');
$c1 = $this->input->post('c1');
$c2 = $this->input->post('c2');
$cc = $this->input->post('cc');
$cp = $this->input->post('cp');
foreach($emp_his_id as $key => $eid)
{
$emp_his_pk = $eid;
$inserte = array();
$inserte['company_name']= $cn[$key];
$inserte['from_date']= $fd[$key];
$inserte['to_date']= $td[$key];
$inserte['type_of_buisness']= $tb[$key];
$inserte['company_addres_lane_1']= $c1[$key];
$inserte['company_addres_lane_2']= $c2[$key];
$inserte['c_city']= $cc[$key];
$inserte['c_pincode']= $cp[$key];
$inserte['updated_on'] = date("Y-m-d");
$up_emp_history=$this->Frontend_model->update_employe($inserte=array(),$emp_his_pk);
}
}
希望这对你有用
