我的模态对话框表单没有使用ajax提交给php中的控制器

问题描述:

In modal dialog form submit value are not passed in to the my controller

function save()
{
    var url;
    url = "<?php echo site_url('index.php/User/book_update')?>";
    $.ajax({
        url : url,
        type: "POST",
        data: $('#form').serialize(),
        dataType: "JSON",
        success: function(data)
        {
            $('#modal_form').modal('hide');
        },
        error: function (jqXHR, textStatus, errorThrown)
        {
            alert('Error adding / update data');
        }
    });
}

while submitting form button no response only Error adding / update data shows

            public function book_update()
            {
            $markid= $this->input->post('markid');
            $subcode=$this->input->post('subcode');
            echo $markid;
            echo $subcode;
            }

在模态对话框中,提交值不会传入我的控制器 p>

  function save()
 {
 var url; 
 url =“&lt;?php echo site_url('index.php / User / book_update')?&gt;”; 
 $ .ajax({  
 url:url,
 type:“POST”,
 data:$('#form')。serialize(),
 dataType:“JSON”,
 success:function(data)
 {\  n $('#modal_form')。modal('hide'); 
},
 error:function(jqXHR,textStatus,errorThrown)
 {
 alert('添加/更新数据时出错'); 
 提交表单按钮时没有响应错误添加/更新数据显示 p> 
 
 
   public function book_update()
 {
 $ markid = $ this-&gt; input-&gt; post('markid'); 
 $ subcode = $ this-&gt; input-&gt; post('subcode  '); 
 echo $ markid; 
 echo $ subcode; 
} 
  code>  pre> 
  div>

Hope this will help you

Your url should be like this :

url = "<?php echo site_url('User/book_update')?>";

Instead of this :

url = "<?php echo site_url('index.php/User/book_update')?>";

js function should be like this :

function save()
{
    var url;
    url = "<?php echo site_url('User/book_update')?>";
    $.ajax({
        url : url,
        type: "POST",
        data: $('#form').serialize(),
        dataType: "JSON",
        success: function(data)
        {
            $('#modal_form').modal('hide');
        },
        error: function (jqXHR, textStatus, errorThrown)
        {
            alert('Error adding / update data');
        }
    });
}

Your controller's book_update method should be like this :

public function book_update()
{
   $markid = $this->input->post('markid');
   $subcode = $this->input->post('subcode');
   $array = array('markid' => $markid);
   echo json_encode($array);
   exit;
}
