如何将ID值从视图传递到Codeigniter中的控制器

Question

I need to pass a id value from view to controller but i have 2 options

1. using anchor tag with uri segment 2.with hidden field form

I think both cant be used , if possible please guide me

<?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">
   <? } ?>

here is my controller

  <?php 
   function array_storage($id) 

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

here is my array

    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" } } } }

Answer 1

I tried the following code in my local please see at it if this is similar to your problem then find and replace accordingly.I have tested this code and it works fine.

//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

why not try this

<?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']?>" />

Then controller

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 
     }
}
