我试图在CodeIgniter中创建一个只有不超过5个字段的单页CRUD。我的问题是它没有将数据插入数据库，我一直在调试这个，但我无法弄清楚问题是什么。我错过了什么？
形式：
<div class="col-md-4 col-sm-6 col-xs-12">
<div class="activity-item">
<form id="agencyForm" enctype="multipart/form-data" method="POST" class="form-horizontal">
<div class="form-body">
<input type="hidden" value="" name="agency_id" />
<div class="form-group">
<div class="col-md-12">
<input name="agency_name" id="agency_name" placeholder="Agency Name" class="form-control" type="text">
<?php echo form_error('agency_name','<span class="help-block">','</span>'); ?>
</div>
</div>
<div class="form-group">
<div class="col-md-12">
<input name="category" id="category" placeholder="Category" class="form-control" type="text">
<?php echo form_error('category','<span class="help-block">','</span>'); ?>
</div>
</div>
<div class="form-group">
<div class="col-md-12">
<input name="address" id="address" placeholder="Address" class="form-control" type="text">
<?php echo form_error('address','<span class="help-block">','</span>'); ?>
</div>
</div>
<div class="form-group">
<div class="col-md-12">
<input name="acronym" id="acronym" placeholder="Acronym" class="form-control" type="text">
<?php echo form_error('acronym','<span class="help-block">','</span>'); ?>
</div>
</div>
</div>
<button type="submit" value="submit " id="btnSave" onclick="save(this.agencyForm); return false" class="btn btn-effect">Save</button>
</form>
</div>
<div class="clear"> </div>

控制器：
public function save_c() {
var_dump($this - > input - > post(NULL, TRUE));
$data = array(
'agency_name' => $this - > input - > post('agency_name'),
'category' => $this - > input - > post('category'),
'address' => $this - > input - > post('address'),
'acronym' => $this - > input - > post('acronym'),
);
$insert = $this - > agency - > save_now($data);
echo json_encode(array("status" => TRUE));
}
型号：
public function save_now($data)
{
$this->db->insert($this->table, $data);
return $this->db->insert_id();
}
注意：当我更改URL时，它会将数据插入数据库：
$.ajax({
// url: url,
url: "<?php echo site_url('agency/save_c')?>",
答案 0 :(得分：0)
你这里有问题。您尚未在任何地方指定save_method。根据您的逻辑定义save_method或删除此if条件并直接指定插入URL
if (save_method == 'add') {
url = "<?php echo site_url('agency/save_c')?>";
} else {
url = "<?php echo site_url('agency/update')?>";
}
您可以直接插入
url = "<?php echo site_url('agency/save_c')?>";
