在此code,点击等按钮后,该数据在数据库中添加了。我想现在要做的是,我想加入数据后,我就总喜欢询问所选择的项目,并且无需加载页面显示。
In this code, after clicking the like button, the data is added in the database already. What I wanted to do now is I would like after adding the data, I will query the total like of the chosen item and display it without loading the page.
这是我的code现在:
This is my code for now:
我的观点:
<p id='state'><i class='fa fa-thumbs-up'></i><span id="likeThis"><?php echo $countLike;?></span> likes • <i class='fa fa-thumbs-down'></i><?php echo $countDisLike;?> dislikes •<i class='fa fa-thumbs-down'></i><a href='<?php echo base_url();?>index.php/photoCheese/deleteUploadPic/<?php echo $row['uploadID'];?>'>Delete Picture</a></p>
<input type="button" onclick="getVal(this.value)" class='detailButton1' name='like_name' id='like_id' value='<?php echo $link;?>' title='Like this post'><i class='fa fa-thumbs-up'></i> Like</input>
JavaScript的:
Javascript:
函数getVal(值)
{
jQuery.ajax({
键入:GET,
网址:?&LT; PHP的回声BASE_URL();&GT;的index.php / photoCheese / like_total /,
数据类型:JSON,
数据:{like_id:值},
成功:函数(RES){
警报(res.no_likes);
如果(RES){
jQuery的(#likeThis)的HTML(res.no_likes)。
}
}
});
function getVal(value)
{
jQuery.ajax({
type:"GET",
url: "<?php echo base_url();?>index.php/photoCheese/like_total/",
dataType:'json',
data: {like_id : value},
success: function(res){
alert(res.no_likes);
if(res){
jQuery("#likeThis").html(res.no_likes);
}
}
});
控制器:
public function like_total(){
$id = $this->session->userdata('userID');
$upload = $this->input->get('like_id');
$data = array('like' => 1,
'userID'=>$id,
'uploadID'=>$_GET['like_id']);
$result = $this->photoCheese_model->get_like_total($data,$upload);
return json_encode($result);
}
型号:
public function get_like_total($data,$uplaod){
$success = $this->db->insert('tbl_like',$data);
if($success){
$this->db->select('uploadID,SUM(`like`) as no_likes',false);
$this->db->where('uploadID',$upload);
$this->db->where('like !=',2);
$query = $this->db->get();
}
return $query->result_array();
}
这code将不会显示total_likes。有什么不对的呢?
This code will not display the total_likes. What's wrong with this one?
在所有的帮助和研究。这是此问题的运行code
After all the helps and research. This is the running code of this problem.
在查看:
<p id='state'><i class='fa fa-thumbs-up'></i><span class="likeThis"><?php echo $countLike;?></span> likes • <i class='fa fa-thumbs-down'></i><?php echo $countDisLike;?> dislikes •<i class='fa fa-thumbs-down'></i><a href='<?php echo base_url();?>index.php/photoCheese/deleteUploadPic/<?php echo $row['uploadID'];?>'>Delete Picture</a></p>
<input type="button" onclick="getVal(this.value)" class='detailButton1' name='like_name' id='like_id' value='<?php echo $link;?>' title='Like this post'><i class='fa fa-thumbs-up'></i> Like</input>

这code现在完美运行。感谢您的帮助反正。
This code runs perfectly now. Thanks for the help anyway.
