在codeigniter中批量更新所有表单输入数据

Question

我想弄清楚为什么我在 codeigniter 中的批量更新不起作用。

这是我的代码：

<?php echo form_open('about/update_approach',array('class' => 'approach-form')) ?>

<? foreach ($approach_content as $i=>$approach): ?>
<input type="hidden" name="id[]" value="<?= $approach['id'] ?>">
<div class="admin-group ">
    <div class="admin-form-item">
        <label for="title">Title</label>
        <input type="text" maxlength="128" value="<?= $approach['title']; ?>" required name="title[]">
    </div>
    <div class="admin-form-item">
        <label for="title">Text</label>
        <input type="text" maxlength="256" value="<?= $approach['text']; ?>" required name="text[]">
    </div>
</div>
<? endforeach ?>


<?php echo form_submit($dataSubmit);?>

<?php echo form_close(); ?>

型号：

public function update_approach(){
        $data = $this->input->post(NULL,TRUE);
        $this->db->update_batch('1985_approach', $data, 'id');
}

但是如果我这样做，我会收到错误消息：

One or more rows submitted for batch updating is missing the specified index.

如果我做 print_r($this-input->post());

<?php
Array(
    [id] => Array(
        [0] => 1[1] => 2[2] => 3[3] => 4[4] => 5[5] => 6
    ) [title] => Array(
        [0] => CREATIVEZ[1] => CURATION[2] => ARTISTS[3] => PRODUCTION[4] => ENGAGEMENT[5] => RESULTS
    ) [text] => Array(
        [0] => Fromconceptthroughexecution,

很久没用Code Igniter了。我检查了文档，你发现了这个：

$data = array(
   array(
      'title' => 'My title' ,
      'name' => 'My Name 2' ,
      'date' => 'My date 2'
   ),
   array(
      'title' => 'Another title' ,
      'name' => 'Another Name 2' ,
      'date' => 'Another date 2'
   )
);

$this->db->update_batch('mytable', $data, 'title');

您确实拥有正确的数据，但错误的结构。将数据转换为：

array(
    array(
          'id'=>1,
          'title'=>'CREATIVEZ',
          'text'=>'some text'
         ),
    array(
          'id'=>2,
           title'=>'CURATION',
           'text'=>'some text'
         )
 );

在PHP中你经常使用关联数组而不是传统的对象。因此，将 php 数组的单个条目视为传统对象。
