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 for($i=0;$i"; }
