我对此问题有些困惑,因为到本地服务器的所有ADD和RETRIEVE数据都运行良好。但是不在实时服务器上。
下面是我的代码:
AJAX:
function baseUrlAction(){
return location.protocol + "//" + location.host + "/json/ajax/ajax_controller.php";
}
function Modal_value_display($id_value){
var id = $id_value;
$.ajax({
type : 'POST',
url : baseUrlAction() + '?btn=process_get_projects_value',
context : this,
dataType : 'json',
data : {
project_id : id
},
error : function(ts){
console.log(ts.responseText);
},
success : function(data){
var row = "";
if(jQuery.isEmptyObject(data)){
}else{
$.each(data, function(key,value){
var prev_val = value.pro_img_id;
var arr = prev_val.split(",");
for(var x=0;x<arr.length;x++){
if(x == 0){
row += '<div class="item active">';
row += '<img src="img/project_img/'+arr[x]+'.jpg">';
row += '</div>';
}else{
row += '<div class="item">';
row += '<img src="img/project_img/'+arr[x]+'.jpg">';
row += '</div>';
}
}
$('#item_gallery').html(row).fadeIn('slow').slideDown('slow');
document.getElementById("Project_name").innerHTML = value.pro_name;
document.getElementById("Project_description").innerHTML = value.pro_description;
document.getElementById("placeholder_code").href = value.pro_code;
document.getElementById("placeholder_site").href = value.pro_website;
});
slider_next_back();
}
}
});
}
在这种情况下,我需要显示来自服务器的动态模式值。这就是为什么我使用AJAX方法实现目标的原因。但是不幸的是,当我尝试使用实时服务器时,它不起作用。我不确定我是否以正确的方式使用了该方法,这将是控制台显示中的错误,这很难弄清楚。

AJAX控制器:
<?php
class Json_Controller{
public function __construct(){
$button=null;
if(isset($_GET['btn'])){
$button = $_GET['btn'];
}
switch($button){
case 'process_get_projects_value':
$this->process_get_projects_value();
break;
}
}
public function process_get_projects_value(){
include 'ajax_model.php';
$arr = array();
$error = false;
$data['result_project'] = $model->process_get_projects_value($_POST);
if($data['result_project']){
foreach($data['result_project'] as $row){
$arr[] = array('pro_img_id'=>$row['pro_img_id'],
'pro_name'=>$row['pro_name'],
'pro_description'=>$row['pro_description'],
'pro_code'=>$row['pro_code'],
'pro_website'=>$row['pro_website']);
}
}
echo json_encode($arr);
}
}
$contros = new Json_Controller();
?>
AJAX模型:
<?php
class Json_Model{
var $con;
var $logged;
var $dbhost;
var $dbuser;
var $dbpass;
var $dbname;
function __construct() {
$this->dbhost = 'localhost';
$this->dbuser = '******';
$this->dbpass = '******';
$this->dbname = '******';
$this->InitDB();
}
function InitDB(){
$this->con = mysqli_connect($this->dbhost, $this->dbuser, $this->dbpass) or die(mysqli_error($this->con));
mysqli_select_db($this->con, $this->dbname) or die(mysqli_error($this->con));
session_start();
}
function query($query){
return mysqli_query($this->con,$query);
}
function free_result($query){
return mysqli_free_result($query);
}
function num_rows($query){
return mysqli_num_rows($query);
}
function fetch_data($query){
return mysqli_fetch_assoc($query);
}
public function process_get_projects_value($post){
$data="";
$query = $this->query('SELECT * FROM projects_tbl where pro_id = "'.$post['project_id'].'" and status = 1 ');
if($this->num_rows($query)>0){
while($yu = $this->fetch_data($query)){
$data[] = $yu;
}
return $data;
}else{
return FALSE;
}
}
}
$model = new json_model();
?>
我要花两(2)天的时间来解决此问题,因为我找不到解决方案。 :(任何人都可以帮助我吗?
