ST 可以把数据包装成json式发送到php端 cartItemsStore = Ext.getStore('cartitemsconvert');var allData = [];cartItemsStore.each(function(records){allData.push(records.getData());});var dataToBeSentToServer = Ext.JSON.encode(allData);console.lo
ST 可以把数据包装成json格式发送到php端
cartItemsStore = Ext.getStore('cartitemsconvert');
var allData = [];
cartItemsStore.each(function(records){
allData.push(records.getData());
});
var dataToBeSentToServer = Ext.JSON.encode(allData);
console.log(dataToBeSentToServer);然后用jsonp或是ajax将数据传输到PHP端
Ext.data.JsonP.request({
url: 'http://londit-50c03e41547f8.com.1130.url-test.com/dingcan/php/save-orders.php',
callbackKey: 'callback',
params: {
sendData:dataToBeSentToServer
},
timeout:2000,
success: function(result, request) {
console.log('提交数据成功');
}
});然后PHP怎么获得这些json数据呢？红色部分是php的问题。如果不用stripslashes转换。stripslashes() 函数删除由 addslashes() 函数添加的反斜杠。否则数据打印出来是空，还有个解决办法就是：The fix was to turn off magic_quotes in php.ini. If you do this, you will no longer need the call to stripslashes().
$sendData = $_REQUEST['sendData']; $jsondata = stripslashes($sendData); //$sendData = '[{"id":"1","food":"\u5f20\u96ea\u6885","age":"27","subject":"\u8ba1\u7b97\u673a\u79d1\u5b66\u4e0e\u6280\u672f"},{"id":"2","food":"\u5f20\u6c9b\u9716","age":"21","subject":"\u8f6f\u4ef6\u5de5\u7a0b"}]'; $arrayData = json_decode($jsondata); foreach($arrayData as $obj){ echo "id：".$obj->food."
"; }
另外附上PHP两种解析json数据的方法：
在PHP代码中处理JSON 格式的字符串的两种方法：唯一不同已经highlight出来了
方法一：
$json ='[{"id":"1","name":"\u5f20\u96ea\u6885","age":"27","subject":"\u8ba1\u7b97\u673a\u79d1\u5b66\u4e0e\u6280\u672f"},{"id":"2","name":"\u5f20\u6c9b\u9716","age":"21","subject":"\u8f6f\u4ef6\u5de5\u7a0b"}]';
$students = json_decode($json);//得到的是 object
foreach($students as $obj){
echo "姓名：".$obj->name."年龄：".$obj->age." 专业：".$obj->subject."
";
}方法二：
$json ='[{"id":"1","name":"\u5f20\u96ea\u6885","age":"27","subject":"\u8ba1\u7b97\u673a\u79d1\u5b66\u4e0e\u6280\u672f"},{"id":"2","name":"\u5f20\u6c9b\u9716","age":"21","subject":"\u8f6f\u4ef6\u5de5\u7a0b"}]';
$students = json_decode($json, true);//得到的是 array
