[英]Issue with insert into sql query
$.ajax({
url: 'http://localhost/xampp/htdocs/ajax.php',
contentType: 'application/json',
type: 'post',
data: {
//score is a new variable and count2 is an integer variable which i want to send it to the database "score":"count2" }, // score是一个新变量,count2是一个整数变量,我想将其发送到数据库“ score”:“ count2”},
success: function () {
alert("ok");
},
error: function () {
alert("error");
}
});
The above code alerts me "ok". 上面的代码提醒我“确定”。
function connect(){
$connect = mysql_connect('localhost','root','') or die("ERROR");
$connect2Database = mysql_select_db('fypdb', $connect);
return $connect;
}
if(isset($_POST)){
if($connect = connect()){
$query = "INSERT INTO fypdbtable (score) VALUES ('".$_POST['score']."');";
$completeQuery = mysql_query($query, $connect);
}
}
I think the problem is on "insert into" query because in ajax.php prompts me Notice: Undefined index: score in C:\\xampp\\htdocs\\xampp\\htdocs\\ajax.php on line 14 where it is the query line 我认为这个问题是在“插入”查询,因为在ajax.php提示我注意:未定义指数:得分在C:\\ XAMPP \\ htdocs中\\ XAMPP \\ htdocs中\\上线14,在那里它是查询行ajax.php
Any help would be appreciate 任何帮助将不胜感激
Problem here is in your ajax code. 问题出在您的ajax代码中。 You are using
contentType: 'application/json'
but you try to acces param in your php script with $_POST
, but post works with form encoded content types. 您正在使用
contentType: 'application/json'
但是您尝试使用$_POST
php脚本中的param,但是post可以使用表单编码的内容类型。 So you can remove contentType from your ajax call and it will use default which is 因此,您可以从ajax调用中删除contentType,它将使用默认值(即
contentType:'application/x-www-form-urlencoded; charset=UTF-8'
EDIT Make your ajax code like that: 编辑使您的ajax代码像这样:
$.ajax({
url: 'http://localhost/xampp/htdocs/ajax.php',
type: 'post',
data: {
"score":"count2"
},
success: function () {
alert("ok");
},
error: function () {
alert("error");
}
});
The "error" message tells you, that $_POST['score'] is not defined. “错误”消息告诉您,未定义$ _POST ['score']。 But thats just a warning.
但这只是一个警告。 If you want to know if your variable is set, use isset() function or turn off warnings in the configuration.
如果您想知道是否设置了变量,请使用isset()函数或在配置中关闭警告。
