Question

我是这个论坛的新手，我很难更新来自文本框值的复选框中的所选值。

场景：

我想更新选定的项目，例如，我想更新Item-2，并且将启用接收到的项目中的文本框，我将输入一个数字（例如1），而总接收中的文本框将使用ajax自动求和。

问题是从总计接收到的值提交后，正在更新的记录为空，但是当我尝试检查和print_r时，值在那里。

还有一件事情是，如果选中了所有复选框并为收到的每个项目输入一个数字，则它只会得到的值是最后一个值，并且将被选中的所有复选框都将被更新。

注意：复选框是一个数组来自总接收的文本框是一个数组

你们能帮我吗？

这是我的用户界面：

控制器：

public function recitem_insert(){

$this->load->model('dbquery');    

$check = $this->input->post('check');    
$total_rec = $_POST['total_rec'];


if(isset($check)){ //Check if check is checked    

  for($i=0;$i<sizeof($check);$i++){
    for($j=0;$j<sizeof($total_rec);$j++){    

    $updateData = array('rec_qty' => $total_rec[$j] );                                                        
    $this->dbquery->modUpdatedynamicval('tblstock', 'id', $updateData, $check[$i]);

       }        
   }//end for loop    

    echo "<script type='text/javascript'>
        alert('Successfully Added!');
        window.close();
        </script>";        

}else{ //End If
      echo 'Please select a checkbox';
    }

}

编辑：

让我们假设，我在item_receive文本框1中输入了1，总接收为10，在item_receive文本框2中为2，总接收为11， item_receive文本框3中为3，总接收为12，

代码：

$check = $this->input->post('check');   
$total_rec = $_POST['total_rec'];

echo 'Check Value';
print_r($check);

echo '<br><br>';

echo 'Total Recieve';
print_r($total_rec);

输出：

Check ValueArray ( [0] => 1 [1] => 2 [2] => 3 ) 

Total RecieveArray ( [0] => 10 [1] => 11 [2] => 12 )

但是，如果我只进入第二个文本框，则输出如下：

Check ValueArray ( [0] => 2 ) 

Total RecieveArray ( [0] => [1] => 11 [2] => )

Answer 1

据我所知，您在确定哪个输入索引是哪个后端方面遇到了问题。您可以在每个输入上设置索引键，如下所示：

<tbody>

<?php                   

$query = $this->db->query("SELECT * FROM tblstock where process_id = '$process_id'");
foreach ($query->result() as $key => $row){           //added key to be used as inputs key                             
?>  

<tr>
<td><input type="checkbox" name="check[<?php echo $key ?>]" id="opt" value="<?php echo $row->id; ?>" onclick="valueChanged()"> </td>
<td><?php echo $row->item_code; ?></td>
<td><?php echo $row->description; ?></td>
<td><?php echo $row->qty_order; ?></td>
<td><?php echo $row->rec_qty; ?></td>

<input type="hidden" name="last_item_rec[<?php echo $key ?>]"  value="<?php echo $row->rec_qty;  ?>">

<td><input type="text" name="item_rec[<?php echo $key ?>]"  id="txt" disabled=""></td>  
<td><input type="text" name="total_rec[<?php echo $key ?>]"></td>  


</tr>

<?php 

}
?>  

</tbody>

在那之后，然后替换for循环：

for($i=0;$i<sizeof($check);$i++){
    for($j=0;$j<sizeof($total_rec);$j++){    

    $updateData = array('rec_qty' => $total_rec[$j] );                                                        
    $this->dbquery->modUpdatedynamicval('tblstock', 'id', $updateData, $check[$i]);

    }        
}//end for loop

有了这个foreach：

foreach ($check as $key => $item) {
    $updateData = array('rec_qty' => $total_rec[$key] );                                                        
    $this->dbquery->modUpdatedynamicval('tblstock', 'id', $updateData, $check[$key]);
}

因此，您不必手动检查total_rec的值，而是只检查提交的check帖子数据。

可以尝试使用行键（项目ID）。使用$ row-> id更新您的阵列键。

<tbody>
    <?php
        $query = $this->db->query("SELECT * FROM tblstock where process_id = '$process_id'");
        foreach ($query->result() as $row){                                       
    ?>  
    <tr>
        <td><input type="checkbox" name="check[]" id="opt" value="<?php echo $row->id; ?>" onclick="valueChanged()"> </td>
        <td><?php echo $row->item_code; ?></td>
        <td><?php echo $row->description; ?></td>
        <td><?php echo $row->qty_order; ?></td>
        <td><?php echo $row->rec_qty; ?></td>
        <input type="hidden" name="last_item_rec[<?php echo $row->id; ?>]"  value="<?php echo $row->rec_qty;  ?>">
        <td><input type="text" name="item_rec[<?php echo $row->id; ?>]"  id="txt" disabled=""></td>  
        <td><input type="text" name="total_rec[<?php echo $row->id; ?>]"></td> 
    </tr>
    <?php
        }
    ?>  
</tbody>

场景类似：

1个项目ID为“ 2”
2个项目ID为“ 3”
3个项目ID为“ 5”

如果您检查第一行和第一行的item_id（$ row-> id）为2，然后输入7，那么您将得到如下数组：-

print_r($_POST['total_rec']);

输出类似：

Array([2]=>7)

您可以使用数组键轻松找到数据

                </thead>
                <tbody>
                  <?php                   
                    //$query = $this->db->query("SELECT * FROM tblstock where process_id = '$process_id'");
                    $new_item_list =  array(
                        array('id'=> '1','item_code'=> 'ITEM-1','description' => 'ITEM Desc', 'qty_order'=> '2','rec_qty'=> '2'),
                        array('id'=> '2','item_code'=> 'ITEM-2','description' => 'ITEM Desc 2', 'qty_order'=> '3','rec_qty'=> '3' ),

                    );
                  foreach ($new_item_list as $row){ 
                    ?>  
                    <tr>
                        <td><input type="checkbox" name="<?php echo $row['id']; ?>[check]" id="opt" value="<?php echo $row['id']; ?>" onclick="valueChanged()"> </td>
                        <td><?php echo $row['item_code']; ?></td>
                        <td><?php echo $row['description']; ?></td>
                        <td><?php echo $row['qty_order']; ?></td>
                        <td><?php echo $row['rec_qty']; ?></td>
                        <input type="hidden" name="<?php echo $row['id']; ?>[last_item_rec]"  value="<?php echo $row['rec_qty'];  ?>">
                        <td><input type="text" name="<?php echo $row['id']; ?>[item_rec]"  id="txt" value='' ></td>
                        <td><input type="text" name="<?php echo $row['id']; ?>[total_rec]" value=''>
                        </td>
                    </tr>
                    <?php 
                  }
                    ?>  
                </tbody>

    <div class="box-footer">
        <button type="submit" class="btn bg-olive btn-flat margin">Submit</button>

提交操作：例如

foreach($_POST as $key => $value){
    if(isset($value['check'])){
        //Row ID of item table $key
       $total = $value['total_rec'] * $value['item_rec'];
        echo "Total Number :".$total."</br>";
       #here is your update query 
    }    
}

Answer 3

从我所看到的

就像其他人说的那样，您很难找到正确的检查项目行。我建议您编辑多维数组中表单的命名方式。赌你不知道吗？

所以在view.php中

<form method="post" action="<?php echo base_url() ?>user/recitem_insert">

<div class="box">
<div class="box-header">
<h3 class="box-title">System ID: <b><?php echo $process_id; ?></b></h3>
</div>
<!-- /.box-header -->
<div class="box-body">
<table id="example1" class="table table-bordered table-striped">
<thead>
<tr>
<th>Action</th>
<th>Item Code</th>
<th>Item Description</th>
<th>Required QTY Order</th>
<th>Last QTY Recieve</th>
<th>Item Recieve</th>
<th>Total Recieve</th>



</tr>
</thead>
<tbody>

<?php                   

//WTF?? it's 2019. Say hello to SQL Injection
$query = $this->db->query("SELECT * FROM tblstock where process_id = '$process_id'");
foreach ($query->result() as $i=>$row){                                       
?>  

<tr>
<td><input type="checkbox" name="data[<?php echo $i;?>][check]" id="opt" value="<?php echo $row->id; ?>" onclick="valueChanged()"> </td>
<td><?php echo $row->item_code; ?></td>
<td><?php echo $row->description; ?></td>
<td><?php echo $row->qty_order; ?></td>
<td><?php echo $row->rec_qty; ?></td>

<input type="hidden" name="data[<?php echo $i;?>][last_item_rec]"  value="<?php echo $row->rec_qty;  ?>">

<td><input type="text" name="data[<?php echo $i;?>][item_rec]"  id="txt" disabled=""></td>  
<td><input type="text" name="data[<?php echo $i;?>][total_rec]"></td>  


</tr>

<?php 
}
?>  

</tbody>
<tfoot>

</tfoot>
</table>
</div>
<!-- /.box-body -->
</div>

<div class="box-footer">
<button type="submit" class="btn bg-olive btn-flat margin">Submit</button>
</div>

</form>

，您可以轻松循环浏览每一行的数据，同时验证是否选中了该复选框

 <?php
//simple way of traversing the data
if ( isset( $_POST['data'] ) )
{
    echo '<table>';
    foreach ( $_POST['data'] as $d )
    {
        //you have all the data here
        //start checking on checked box
        if(isset($d['check']))
        {
            echo '<tr>';
            echo '  <td>', $d['last_item_rec'], '</td>';
            echo '  <td>', $d['item_rec'], '</td>';
            echo '  <td>', $d['total_rec'], '</td>';
            echo '</tr>';
        }
    }
    echo '</table>';
}

Answer 4

您的复选框都具有相同的ID，这总是会导致问题。更改循环中复选框的ID。

<div
  v-for="item in faqItems"
  :key="item.id"
>
  <span class="faq-item-title" style="white-space: pre-wrap;">
    {{ item.title }}
  </span>
  <span class="faq-item-details" style="white-space: pre-wrap;">
    {{ item.text }}
  </span>
  <svg-icon name="chevron-down"></svg-icon>
</div>
