这是我的两个表，即 bills 和 Product_list。
product_list 表看起来像这样
id bill_id description quantity amount
19 18 ["item1","item2","item3"] ["2","1","2"] ["100","100","150"]
账单表看起来像这样..
id invoice_no pp_no
18 JED00018 34533
Controller 看起来像这样..
function edit_bill($id)
{
var_dump($id);
$this->form_validation->set_rules('pp_no',Number','required');
if($this->form_validation->run()==true)
{
$data=array('pp_no'=>$this->input->post('pp_no'));
if($this->Bills_model->bill_update($id,$data))
{
$this->session->set_flashdata('success_msg','Bills Updated successfully.');
redirect('bills.html');
}
}
$data['result']=$this->Bills_model->view_bill_by_id($id);
$data['search_url'] = 'bills.html';
$data['active'] = 'bill';
$data['module'] = 'admin/edit_bill';
$this->load->view('admin/master',$data);
}
模型看起来像
function bill_update($id,$data)
{
$this->db->join('product_list','product_list.bill_id=bills.id');
$this->db->where('bills.id',$id);
$this->db->update('bills',$data);
$data['description']=$this->input->post('description',true);
$description=json_encode($data['description']);
$data['quantity']=$this->input->post('quantity',true);
$quantity=json_encode($data['quantity']);
$amount=json_encode($this->input->post('amount',true));
$data2=array('description'=>$description,'quantity'=>$quantity,'amount'=>$amount);
$this->db->join('bills','bills.id=product_list.bill_id');
$this->db->where('product_list.bill_id',$id);
$this->db->update('product_list',$data2);
if($this->db->affected_rows() != 0 )
{
return TRUE;
}
else
{
return FALSE;
}
}
我的 View 表单如下所示
<form class="form-horizontal" method="post" action="<?php echo base_url(); ?>bills/edit_bill/<?php echo $result->id; ?>">
<div class="clearfix"></div>
<div class="form-group">
<label for="pp_no" class="col-sm-2 control-label">PP NO/ID</label>
<?php echo form_error('pp_no'); ?>
<div class="col-sm-3" style="padding-top:5px;">
<input type="text" class="form-control" name="pp_no" id="pp_no" value="<?php echo $result->pp_no;?>" >
<input type="hidden" name="id" value="<?php echo $result->id;?>">
</div>
</div>
<table id="items">
<tr>
<th>Item No</th>
<th>Description</th>
<th>Amount</th>
<th>Quantity</th>
<th>Total</th>
</tr>
<?php $description=json_decode($result->description)?>
<?php $amount=json_decode($result->amount)?>
<?php $quantity=json_decode($result->quantity);?>
<?php foreach($description as $index => $row){
?>
<tr class="item-row">
<td class="item-no"><div class="delete-wpr"><textarea class="textarea"></textarea><a class="delete" href="javascript:;" title="Remove row">X</a></div></td>
<td class="description"><textarea class="textarea" name="description[]"><?php echo $row;?></textarea></td>
<td><textarea name="amount[]" class="cost textarea"><?php echo $amount[$index];?></textarea></td>
<td><textarea name="quantity[]" class="qty textarea"> <?php echo $quantity[$index];?></textarea></td>
<td><span class="price"></span></td>
</tr>
<?php }?>
</table>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<input type="hidden" name="id" value="<?php echo $result->id;?>">
<button type="submit" class="btn btn-primary" style="margin-top: 20px;" >Save</button>
</div>
</div>
</form>
在这里，当我更新任何字段并提交时，它会像这样 localhost/edit_bill/19 一样转到 Product_list 的 id，并且不知道为什么会这样。
最佳答案
it's going to the id of product_list like this localhost/edit_bill/19 and don't have any idea why it's going like this.
因为你告诉它!
<form class="form-horizontal" method="post" action="<?php echo base_url(); ?>bills/edit_bill/<?php echo $result->id; ?>">
只要松开将 id 添加到 URL 的部分即可!于是就变成了……
<form class="form-horizontal" method="post" action="<?php echo base_url();?>bills/edit_bill">
您已经在表单中“发布”了 ID...
<input type="hidden" name="id" value="<?php echo $result->id;?>">
