Question

我需要将id值从视图传递给控制器，但我有2个选项

将锚标记与uri段一起使用 2.具有隐藏的字段形式

我认为两者都无法使用，如果可能请指导我

<?php for($i=0;$i<count($array['value']);$i++) { ?>
<?php $id= $array['value'][$i]['arrayIndex']; ?>
      echo form_open('controller/array_storage/'.$id)
 <input type="hidden" name="<?php echo 'foo'.$i ?>" value="<?php  echo $array['value'][$i]['foo']?>" /> 
 <input type="hidden" name="<?php echo 'boo'.$i?>" value="<?php  echo $array['value'][$i]['boo']?>" />
 <input type="hidden" name="<?php echo 'bar'.$i?>" value="<?php  echo $array['value'][$i]['bar']?>" />
 <input type="submit">
   <? } ?>

这是我的控制器

  <?php 
   function array_storage($id) 

  {
 $foo = $this->input->post('foo'.$id);
 $boo =   $this->input->post('boo'.$id);
 $bar =  $this->input->post('bar'.$id);
 }
 ?>

这是我的数组

    array(4) { ["aa"]=> int(12) ["b"]=> string(4) "2222" ["c"]=> string(3) "232" ["array"]=> array(4) { [0]=> array(7) { ["test"]=> string(5) "23132" ["aaa"]=> int(131) ["bbb"]=> string(4) "sgsg" ["ccc"]=> string(6) "qweqrq" ["ddd"]=> NULL ["eee"]=> int(0) ["value"]=> array(4) { ["foo"]=> int(46546) ["boo"]=> string(6) "231231" ["bar"]=> string(4) "test" ["TDS"]=> string(3) "0.0" } } [1]=> array(7) { ["test"]=> string(5) "23132" ["aaa"]=> int(131) ["bbb"]=> string(4) "sgsg" ["ccc"]=> string(6) "qweqrq" ["ddd"]=> NULL ["eee"]=> int(0) ["value"]=> array(4) { ["foo"]=> int(46546) ["boo"]=> string(6) "231231" ["bar"]=> string(4) "test" ["TDS"]=> string(3) "0.0" } } [2]=> array(7) { ["test"]=> string(5) "23132" ["aaa"]=> int(131) ["bbb"]=> string(4) "sgsg" ["ccc"]=> string(6) "qweqrq" ["ddd"]=> NULL ["eee"]=> int(0) ["value"]=> array(4) { ["foo"]=> int(46546) ["boo"]=> string(6) "231231" ["bar"]=> string(4) "test" ["TDS"]=> string(3) "0.0" } } [3]=> array(7) { ["test"]=> string(5) "23132" ["aaa"]=> int(131) ["bbb"]=> string(4) "sgsg" ["ccc"]=> string(6) "qweqrq" ["ddd"]=> NULL ["eee"]=> int(0) ["value"]=> array(4) { ["foo"]=> int(46546) ["boo"]=> string(6) "231231" ["bar"]=> string(4) "test" ["TDS"]=> string(3) "0.0" } } } }

帮我解决问题

让json轻松查看

{
  "aa": 12,
  "b": "2222",
  "c": "232",
  "array": [
    {
      "arrayIndex": "1",
      "aaa": 131,
      "bbb": "sgsg",
      "ccc": "qweqrq",
      "ddd": null,
      "eee": 0,
      "value": {
        "foo": 46546,

      }

Answer 1

我在本地尝试了以下代码，如果这与您的问题类似，请查看并相应地找到并替换。我已经测试了此代码并且工作正常。

//This is your view

<?php for($i=0;$i<3;$i++) { ?>
<?php $id= '1'; 
      echo form_open('index.php/welcome/array_storage/'.$id)?>
 <input type="hidden" name="<?php echo 'foo'.$i ?>" value="<?php  echo "2"?> /> 
 <input type="hidden" name="<?php echo 'boo'.$i?>" value="<?php  echo "23"?> />
 <input type="hidden" name="<?php echo 'bar'.$i?>" value="23" />
 <input type="submit">

   <?php } ?>

//this is controller function

    function array_storage($id) 
 {
    echo $id;
     echo $this->input->post('foo'.$id);
      echo $this->input->post('boo'.$id);
 }

Answer 2

为什么不试试这个

<?php $total_count = count($array['value']); 
     for($i=0;$i<total_count ;$i++) { ?>
       <?php $id= $array['value'][$i]['arrayIndex']; ?>
       // @note the name attribute of the form is set
       echo form_open('controller/array_storage/'.$id , "name='form-storage-$id'")

 <input type="hidden" name="foo" value="<?php  echo $array['value'][$i]['boo']?>" />
 <input type="hidden" name="bar" value="<?php  echo $array['value'][$i]['bar']?>" />

然后控制器

function array_storage($id = '') 
{
   $array = get_the_array();

   if( array_key_exists( $id , $array )
   {

      $foo = $this->input->post('foo');
      $boo =   $this->input->post('boo');
      $bar =  $this->input->post('bar');

    else
    {
        // error : invalid index 
     }
}
