こんにちは、ajax クエリを作成しようとしていますが、結果が返されると、応答としてUndefinedが返されます。「hello」に設定されていても「h」として返される「hello」というオブジェクトを除いて。ajaxがデータを送信する方法と関係があると感じていますが、何が問題なのかわかりません。どんな助けでも大歓迎です。
ここにアヤックスがあります
function doSearch() {
var emailSearchText = $('#email').val();
var keyCardSearchText = $('#keyCard').val();
var userNameSearchText = $('#userName').val();
var pinSearchText = $('#pin').val();
var passwordSearchText = $('#password').val();
$.ajax({
url: 'process.php',
type: 'POST',
data: {
"hello": "hello",
"emailtext": "emailSearchText",
"keycardtext": "keyCardSearchText",
"usernametext": "userNameSearchText",
"pinText": "pinSearchText",
"passwordtext": "passwordSearchText"
},
dataType: "json",
success: function (data) {
alert(data.msg);
var mydata = data.data_db;
alert(mydata[0]);
}
});
}
次に、ここにphpがあります
include_once('connection.php');
if(isset($_POST['hello'])) {
$hello = $_POST['hello'];
$emailSearchText = mysql_real_escape_string($_POST['emailSearchText']);
$keyCardSearchText = mysql_real_escape_string($_POST['keyCardSearchText']);
$userNameSearchText = mysql_real_escape_string($_POST['userNameSearchText']);
$pinSearchText = mysql_real_escape_string($_POST['pinSearchText']);
$passwordSearchText = mysql_real_escape_string($_POST['passwordSearchText']);
$query = "SELECT * FROM Students WHERE (`User name`='$userNameSearchText' OR `Email`='$emailSearchText' OR `Key Card`='$keyCardSearchText')AND(`Password`='$passwordSearchText'OR `Pin`='$pinSearchText')";
$students = mysql_query($query);
$count = (int) mysql_num_rows($students);
$data = array();
while($student = mysql_fetch_assoc($students)) {
$data[0] = $student['First Name'];
$data[1] = $student['Last Name'];
$data[2] = $student['Date of last class'];
$data[3] = $student['Time of last class'];
$data[4] = $student['Teacher of last class'];
$data[5] = $student['Membership Type'];
$data[6] = $student['Membership Expiration Date'];
$data[7] = $student['Free Vouchers'];
$data[8] = $student['Classes Attended'];
$data[9] = $student['Classes From Pack Remaining'];
$data[10] = $student['5 Class Packs Purchased'];
$data[11] = $student['10 Class Packs Purchased'];
$data[12] = $student['Basic Memberships Purchased'];
$data[13] = $student['Unlimited Memberships Purchased'];
$data[14] = $student['Groupon Purchased'];
};
echo json_encode(array("data_db"=>$data, "msg" => "Ajax connected. The students table consist ".$count." rows data", "success" => true));
};
