Question

首先我正在使用该脚本

$.ajax({
		type: 'POST',
		url: 'ajax/registration.php',
		data: dataObj,
		dataType: 'json',
		async: true,
	})
	.done(function ajaxDone(data) {
		// Whatever data is 
		if(data.redirect !== undefined) {
			window.location = data.redirect;
		} else if(data.error !== undefined) {
			_error
				.text(data.error)
				.show();
		}
	})
	.fail(function ajaxFailed(e) {
		// This failed 
		console.log(e);
	})
	.always(function ajaxAlwaysDoThis(data) {
		// Always do
		console.log('Always');
	})

我正在创建一个注册系统，我应该将DataObj发送到服务器，但是ajax失败并给我该错误：-

Object { readyState: 4, getResponseHeader: getResponseHeader(), getAllResponseHeaders: getAllResponseHeaders(), setRequestHeader: setRequestHeader(), overrideMimeType: overrideMimeType(), statusCode: statusCode(), abort: abort(), state: state(), always: always(), catch: catch(), … } main.js:46:3

以及有关错误消息的更多详细信息：-

{…}abort: function abort()always: function always()catch: function catch()done: function add()fail: function add()getAllResponseHeaders: function getAllResponseHeaders()getResponseHeader: function getResponseHeader()overrideMimeType: function overrideMimeType()pipe: function pipe()progress: function add()promise: function promise()readyState: 4responseText: "<br />\n<b>Fatal error</b>:  Uncaught PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '0' for key 'PRIMARY' in /opt/lampp/htdocs/Registration and login System/ajax/registration.php:27\nStack trace:\n#0 /opt/lampp/htdocs/Registration and login System/ajax/registration.php(27): PDOStatement-&gt;execute()\n#1 {main}\n  thrown in <b>/opt/lampp/htdocs/Registration and login System/ajax/registration.php</b> on line <b>27</b><br />\n"setRequestHeader: function setRequestHeader()state: function state()status: 200statusCode: function statusCode()statusText: "OK"then: function then()<prototype>: Object { … } main.js:46:3

有人可以告诉我这个错误可能在哪里/什么地方吗？
