型号代码：

function update_absconding_checklist()
	{

		$post_array = $this->input->post();
		$id = $this->input->post('checklist_id'); //array of id
		$action_item = $this->input->post('action_item'); //array of item name
		$sequence = $this->input->post('sequence'); //array or qty


$updateArray = array();

for($x = 0; $x < sizeof($id); $x++){

   
    $updateArray[] = array(
        'checklist_id'=>$id[$x],
        'action_item' => $action_item[$x],
        'sequence' => $sequence[$x]
       
    );
} 


$this->db->update_batch('pr_absconding_checklists',$updateArray, 'checklist_id');

按照以下

更改代码

<input type="text" class="form-control" name="action_item[<?php echo $row['checklist_id'];?>]" value="<?php echo $row['action_item']; ?>" readonly>
<input type="checkbox" class="" id="checklist_id<?php echo $row['checklist_id'];?>" name="checklist_id[]" value="1" <?php if($row['status'] == '1') echo 'checked'; ?>>
<input type="text" class="form-control" name="sequence[<?php echo $row['checklist_id'];?>]" id="sequence" value="<?php echo $row['sequence']; ?>">

传递数组中的值

在你的模特中

foreach($id as $key => $value) {
   $updateArray[] = array(
        'checklist_id'=>$value,
        'action_item' => $action_item[$value],
        'sequence' => $sequence[$value]           
    );
}

使用checklist_id作为action_item的键，序列
