[英]Ajax won't pass to $_POST
Having troubles passing the ajax to $_POST
, it is always returning false. 将ajax传递到$_POST
遇到麻烦,它总是返回false。
What I have tried so far: 到目前为止我尝试过的是:
'application/json; charset=UTF-8'
使用contentType: 'application/json; charset=UTF-8'
'application/json; charset=UTF-8'
, 'application/json; charset=UTF-8'
, console.log: Object {readyState: 0, responseText: "", status: 0, statusText: "error"}
在Javascript中删除了dataType, console.log: Object {readyState: 0, responseText: "", status: 0, statusText: "error"}
Object {readyState: 4, responseText: "↵ ↵Failed to hold<br>", status: 200, statusText: "OK"}
使用Javascript中的dataType, Object {readyState: 4, responseText: "↵ ↵Failed to hold<br>", status: 200, statusText: "OK"}
Javascript: Javascript:
$(document).ready(function(){
$("#showcart").click(function(event){
event.preventDefault();
$.ajax({
data: {'jCart':JSON.stringify(cart)},
type: 'POST',
dataType: 'json',
url: 'storecart.php',
contentType:'application/json; charset=UTF-8',
success: function(data){
console.log("Success")
},
error: errorFunction
});
});
});
function errorFunction(){
console.log("Error");
}
Storecart.php Storecart.php
<?php
if(isset($_POST['jCart'])){
$decode = json_decode($_POST['jCart']);
$_SESSION['receive'] = $decode;
$product = $_SESSION['receive'];
}
else{
echo "Failed to hold<br>";
}
?>
Cart.php Cart.php
<?php
session_store();
include(Storecart.php);
?>
On the console, it will say "Error"
. 在控制台上,它将显示"Error"
。
On the cart.PHP, it will say "Failed to hold"
. 在cart.PHP上,它将显示"Failed to hold"
。
What I know is that ajax is not running properly, I don't know how to fix it. 我所知道的是ajax运行不正常,我不知道如何解决它。
ALMOST SOLUTION for ajax, but it can't post for some reason Ajax的最佳解决方案,但由于某种原因无法发布
Don't know why but it worked for me. 不知道为什么,但是对我有用。
Create a function: 创建一个函数:
function showcart(){
var jData = JSON.stringify(cart);
$.ajax({
url:"storecart.php",
type:"post",
data: 'datastring=' + jData,
datatype: "json",
success: function(data){
console.log("SUCCESS")
console.log(jData);
},
error: function(data){
console.log("REDO")
}
});
}
Add it to the javascript: 将其添加到javascript中:
$(document).ready(function(){
$("#showcart").click(function(event){
event.preventDefault();
showcart();
});
});
您没有在任何要发送数据数据的地方声明购物车:{'jCart':JSON.stringify(cart)}
Try to change your code like this : 尝试像这样更改代码:
var dataJcart = {
"var": "example jcart"
};
var dataString = JSON.stringify(dataJcart);
$(document).ready(function(){
$("#showcart").click(function(event){
event.preventDefault();
$.ajax({
url: 'storecart.php',
type: 'POST',
data:{'jCart': dataString},
success: function(data){
console.log(data);
},
error: errorFunction
});
});
});
function errorFunction(){
console.log("Error non");
}
Storecart.php Storecart.php
if(isset($_POST["jCart"]))
{
$decode = json_decode($_POST["jCart"]);
echo $decode->var;
}
