为什么当我的数据库收到包含所有这些帖子的电子邮件时，该消息说我的帖子不可用..
这是我的userinfo.php
<?php
require("config.inc.php");
if (!empty($_POST)) {
//initial query
$query = "Select name, email, password, mobilenumber, address, city, postcode, state FROM user WHERE email = :email ";
$query_params = array(':email' => $_POST['email']);
//execute query
try {
$stmt = $db->prepare($query);
$result = $stmt->execute($query_params);
}
catch (PDOException $ex) {
$response["success"] = 0;
$response["message"] = "Database Error!";
die(json_encode($response));
}
// Finally, we can retrieve all of the found rows into an array using fetchAll
$row = $stmt->fetchAll();
if ($row) {
$response["success"] = 1;
$response["message"] = "Post Available!";
$response["posts"] = array();
$post = array();
do {
// $post = $row["position"];
// $post = $row["state"];
// array_push($response["posts"], $post);
array_push($response["posts"], $row);
} while ($row = $stmt->fetch());
die(json_encode($response));
}
else {
$response["success"] = 0;
$response["message"] = "No Post Available!";
die(json_encode($response));
}
}
else {
?>
<h1>User Info</h1>
<form action="userinfo.php" method="post">
Email:<br />
<input type="email" name="email" value="" />
<br /><br />
<input type="submit" value="Search User" />
</form>
<?php
}
?>
为什么我在文本框中尝试键入我的电子邮件，我的php给了我这个我想要的回复..
{"success":1,"message":"Post Available!",
"posts":[
[
{"name":"Jiawei",
"email":"jiaweitan05@gmail.com",
"password":"123456abcd",
"mobilenumber":"0124331292",
"address":"Bunga Raya",
"city":"Bukit Beruang",
"postcode":"75450",
"state":"Melaka"
}
]
]
}
但我的logcat说No Post available ...我不知道为什么会发生这种情况，即使它应该能够为我检索数据..
