我正在嘗試使用單個表單來插入新資料并更新現有資料的值。我可以輕松顯示表單、獲取資料并更新它，但是當我嘗試插入新資料時，表格沒有出現。這是我的控制器
<div class="card-body">
<small><?php echo validation_errors(); ?></small>
<?php if (isset($packages)) { ?>
<form action="<?= base_url('admin/update_package/' . $packages->id) ?>" method="POST" enctype="multipart/form-data">
<div class="form-group">
<label for="name" class="control-label">Package Name</label>
<input type="text" class="form-control mb-3" name="title" placeholder="Enter Package Name" value="<?php echo !empty($packages->title) ? $packages->title : ''; ?>">
</div>
<div class="form-group">

<div class="form-group">

我的模型
public function insert($data = array())
{
if (!empty($data)) {
$this->db->insert('packages', $data);
return $this->db->insert_id();
}
return false;
}
public function edit($id)
{
$query = $this->db->get_where("packages", array('id' => $id));
return $query->row();
}
public function update($data, $id)
{
return $this->db->update("packages", $data, array('id' => $id));
}
然后控制器

if ($this->input->post('packageData')) {

$this->form_validation->set_rules('title', 'Package Name', 'required');

$this->form_validation->set_rules('status', 'Status', 'required');
// $this->form_validation->set_rules('image', 'Images', 'required');

}

我在這里找到了一個問題以及一個答案和建議，但我仍然無法解決我的問題。
uj5u.com熱心網友回復：
重用表單進行插入和更新的最簡單方法是將表單操作留空。如果表單操作留空，則表單將發送回用于顯示它的同一 URL。如果您使用相同的方法（一種用于插入，一種用于更新）來處理和呈現 from，則此方法有效。
由于您的更新表單處理位于admin/update_package/$id，但您的更新表單呈現位于admin/edit_package/$id，因此您需要指定的表單操作取決于您用于顯示更新表單的 URL。
如果您使用鏈接來admin/update_package/$id顯示更新表單，您可以將表單操作留空（或將其完全洗掉）：<form method="POST" enctype="multipart/form-data">
update_package然后運行表單驗證，然后用于edit_package顯示表單，但 URL 仍然admin/update_package/$id是您要發回的位置，因此不需要表單操作。
在這種情況下，我建議您也將edit_package控制器中的方法設為私有，這樣您就不會意外地通過edit_packageURL 顯示表單：private function edit_package($id)
但是，如果您使用指向/該 URL 的鏈接admin/edit_package/$id來顯示更新表單，則回發到該 URL 不會觸發表單處理，因此在這種情況下您確實需要指定表單操作。
您可以使用該$packages變數來判斷表單是用于插入還是更新，如果存在，則將操作設定為update_packageURL ：$packagesaction="<?= isset($packages) ? base_url('admin/update_package/'.$packages->id) : ''; ?>"
然后 Insert 獲得一個空操作，該操作回發到用于呈現插入表單的同一 URL。
編輯：還要洗掉<?php if (isset($packages))表單周圍的，否則它也不會在插入時顯示。
