我想使用Ajax插入数据。当我单击按钮(接受)时,应插入值1,并将按钮更改为已接受。我试过以下代码
<script>
$(function(){
$('#submit').on('click', function() {
var name = $('#app').val();
if (name.length > 0) {
$.ajax({
url: 'approve.php',
method: 'POST'
data: { app: name },
success: function() {
alert("success");
}
});
}
});
});
</script>
HTML代码
<form action="" method="post">
<input type="hidden" id="app" value="1"/>
<input id='submit' type='submit' value='Accept'>
</form>
approve.php是
$u_id = $_SESSION['UserID'];
$appinfo = $_POST['app'];
$sql = "UPDATE tbl_bides SET selected='$appinfo' WHERE bidder_id = '".$u_id."'" or die(mysql_error());
$Result = mysql_query($sql,$con) or die(mysql_error());
当我跑步时,没有任何事情发生。请帮忙!!

试试这个
HTML
<input type="hidden" value="1" id="app">
<input type="submit" value="SUBMIT" id="submit">
JS
$('#submit').click(function() {
var name = $('#app').val();
$.ajax({
url: 'approve.php',
data:"app="+ name,
success:function(){
alert("success");
}
});
});
approve.php(使用PDO)
include('connection.php');
$u_id = $_SESSION['UserID'];
if(isset($_POST['app'])) {
$appinfo = $_POST['app'];
$queryUpdate = $YourConnectionName->prepare("UPDATE tbl_bides SET selected=:appinfo WHERE bidder_id=:u_id");
$queryUpdate->execute(array(':u_id' => $u_id, ':appinfo'=> $appinfo));
}
connection.php
$username = 'YourUsernameOfDatabase';
$password = 'YourPasswordOfDatabase';
try {
$YourConnectionName = new PDO('mysql:host=Yourhost; dbname=YourDatabaseName', $username, $password);
$YourConnectionName->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$YourConnectionName->exec("SET CHARACTER SET utf8");
} catch (PDOException $e) {
echo 'You are not connected';
$e->getMessage() . "<br/>";
die();
}

你的javascript错了。首先,您正在尝试设置“提交”#39;隐藏表单字段上的事件处理程序。只有<form>
会自然触发submit
事件。其次,您没有设置method
参数,因此$ .ajax通过GET
提交您的数据,这意味着您的PHP代码不会看到任何值。
最好在提交按钮上设置点击事件:
<script>
$(function(){
$('#submit').on('click', function() {
var name = $('#app').val();
if (name.length > 0) {
$.ajax({
url: 'approve.php',
method: 'POST'
data: { app: name },
success: function() {
alert("success");
}
});
}
});
});
</script>
你批准了.php:
$u_id = $_SESSION['UserID'];
$appinfo = $_POST['app'];
$sql = "UPDATE tbl_bides SET selected='$appinfo' WHERE bidder_id = '$u_id'";
$Result = mysql_query($sql, $con) or die(mysql_error());

Add One more parameter in ajax for submitting post data
$.ajax({
url: 'approve.php',
type: 'POST'
data:"app="+ name,
success:function(){
alert("success");
}
}));
