复选框的 Codeigniter 批量更新

Question

我有这样的情况，我想更新一些输入是复选框的数据，我在下面尝试了这段代码。数据已保存在数据库中，但数据保存在另一行中，

For example : I checked color red, yellow and grey for BirdA and I checked dark and blue for BirdD at the same time. In database, color for BirdA saved correctly, but for the 2nd bird, dark and blue saved on BirdB (Should be save on BirdD)

我想解决上面的问题，所以数据应该保存在数据库的正确位置。请检查下面我的代码：

我的数据库Table:

=============================================
| birds | red | blue | grey | yellow | dark | 
=============================================
| BirdA |  0  |   0  |   0  |   0    |   0  |
| BirdB |  0  |   0  |   0  |   0    |   0  |
| BirdC |  0  |   0  |   0  |   0    |   0  |
| BirdD |  0  |   0  |   0  |   0    |   0  |
=============================================

查看：

  <tr>
    <td><input type="hidden" name="birds[]" value='<?php echo $dp['birds']; ?>' /><?php echo $dp['birds']; ?></td>
    <td><p align='center'><input type="text" name="qtt[]" value='<?php echo $dp['qtt']; ?>' tabindex="2" style="width:30px;" /></td>
    <td><p align='center'><input type="checkbox" name="red[]" value='1' <?php if($dp['red']==1) { echo " checked=\"checked\""; } ?> /></td>
    <td><p align='center'><input type="checkbox" name="blue[]" value='1' <?php if($dp['blue']==1) { echo " checked=\"checked\""; } ?> /></td>
    <td><p align='center'><input type="checkbox" name="grey[]" value='1' <?php if($dp['grey']==1) { echo " checked=\"checked\""; } ?> /></td>
    <td><p align='center'><input type="checkbox" name="yellow[]" value='1' <?php if($dp['yellow']==1) { echo " checked=\"checked\""; } ?> /></td>
    <td><p align='center'><input type="checkbox" name="dark[]" value='1' <?php if($dp['dark']==1) { echo " checked=\"checked\""; } ?> /></td>
  </tr>

和控制器：

    $birds= $this->input->post("birds");
        if (empty($this->input->post("birds"))){
            $birds= 0;
        }
    $qtt= $this->input->post("qtt");
        if (empty($this->input->post("qtt"))){
            $qtt= 0;
        }
    $red= $this->input->post("red");
        if (empty($this->input->post("red"))){
            $red= 0;
        }
    $blue= $this->input->post("blue");
        if (empty($this->input->post("blue"))){
            $blue= 0;
        }
    $grey= $this->input->post("grey");
        if (empty($this->input->post("grey"))){
            $grey= 0;
        }
    $yellow= $this->input->post("yellow");
        if (empty($this->input->post("yellow"))){
            $yellow= 0;
        }
    $dark= $this->input->post("dark");
        if (empty($this->input->post("dark"))){
            $dark= 0;
        }

    for($x = 0; $x < sizeof($birds); $x++){
        $reslt[$x] = array(
            "birds"    => $birds[$x],
            "qtt"  => $qtt[$x],
            "red"  => $red[$x],
            "blue"  => $blue[$x],
            "grey"  => $grey[$x],
            "yellow"  => $yellow[$x],
            "dark"  => $dark[$x]
            );
        }
        $this->db->update_batch('db_birds', $reslt, 'birds');

在我执行该代码后，php 出现如下错误：

控制器代码：-

for($x = 0; $x < sizeof($birds); $x++){
        $reslt[$x] = array(
            "birds"    => $birds[$x],
            "qtt"  => $qtt[$x],
            "red"  => $red[$x],
            "blue"  => $blue[$x],
            "grey"  => $grey[$x],
            "yellow"  => $yellow[$x],
            "dark"  => $dark[$x]
            );
        }
$this->db->update_batch('db_birds', $reslt, 'birds');

更改在您的视图代码中：-

 <?php


//sql Query.
//execute Query.


$ii=0;
foreach($dps as $dp){
      $iii = $ii++; 
 <tr>
    <td><input type="hidden" name="birds[<?php echo $iii;?>]" value='<?php echo $dp['birds']; ?>' /><?php echo $dp['birds']; ?></td>
    <td><p align='center'><input type="text" name="qtt[]" value='<?php echo $dp['qtt']; ?>' tabindex="2" style="width:30px;" /></td>
    <td><p align='center'><input type="checkbox" name="red[<?php echo $iii;?>]" value='1' <?php if($dp['red']==1) { echo " checked=\"checked\""; } ?> /></td>
    <td><p align='center'><input type="checkbox" name="blue[<?php echo $iii;?>]" value='1' <?php if($dp['blue']==1) { echo " checked=\"checked\""; } ?> /></td>
    <td><p align='center'><input type="checkbox" name="grey[<?php echo $iii;?>]" value='1' <?php if($dp['grey']==1) { echo " checked=\"checked\""; } ?> /></td>
    <td><p align='center'><input type="checkbox" name="yellow[<?php echo $iii;?>]" value='1' <?php if($dp['yellow']==1) { echo " checked=\"checked\""; } ?> /></td>
    <td><p align='center'><input type="checkbox" name="dark[<?php echo $iii;?>]" value='1' <?php if($dp['dark']==1) { echo " checked=\"checked\""; } ?> /></td>
  </tr>
  }
  
  
?>
