验证功能无法通过PHP和MySQL
function validate(add_app_form){
var valid = true;
var userTxt = document.getElementById("patient_name").value;
var dateTxt = document.getElementById("app_date").value;
var timeTxt = document.getElementById("app_time").value;
var oldName = document.getElementById("select_old").value;
if(userTxt == "" && dateTxt == "" && timeTxt == "" && oldName == "choose")
{
//$("#lblTxt").text("Username and Password are required!");
$('#patient_name').css('border-color', 'red');
$('#app_date').css('border-color', 'red');
$('#app_time').css('border-color', 'red');
$('#select_old').css('border-color', 'red');
$("#add_app_lbl").text("Please Fill all the form");
valid = false;

添加数据我有一个PHP从表单获取值并将其添加到MySQL数据库中的代码。 PHP代码的第一部分，请查看管理员是否从下拉列表中选择一个已存在的患者，然后添加具有原因的约会日期和时间。
然后将值发布到PHP代码中，我们看看在这些日期和时间中是否已经预约。如果没有（$appExistStmtCount == 0）然后去插入预约。
问题是什么都没有添加到数据库，并且看不到任何PHP错误的回应。
这里是PHP代码：
<?php
//Set error reporting on
error_reporting(E_ALL);
ini_set("display_errors", 1);
//Include connection file
require_once('../include/global.php');
$user = $_SESSION['username'];
$id_logged = $_SESSION['login_id'];
if(isset($_POST['add_app_btn'])){
//Values From AJAX
$patient_name = $_POST['patient_name'];
$date_app = $_POST['app_date'];
$time_app = $_POST['app_time'];
$reason = $_POST['app_reason'];
$old_patient_id = $_POST['select_old'];
//If new patient
if($patient_name == "" && $old_patient_id != "choose")
{
try{
//See if date and time exist
$appExist = "SELECT * FROM appointment WHERE id_logged = :id_logged AND date_app = :date_app and time_app = : time_app";
$appExistStmt = $conn->prepare($appExist);
$appExistStmt->bindValue(":id_logged", $id_logged);
$appExistStmt->bindValue(":date_app", $date_app);
$appExistStmt->bindValue(":time_app", $time_app);
$appExistStmt->execute();
$appExistStmtCount = $appExistStmt->rowCount();
if($appExistStmtCount == 0)
{
//Add to appointment table
$appAdd = "INSERT INTO appointment(id_logged, patient_id, date_app, time_app, reason)
VALUES(:id_logged, :patient_id, :date_app, :time_app, :reason)";
$appAddStmt = $conn->prepare($appAdd);
$appAddStmt->bindValue(":id_logged", $id_logged);
$appAddStmt->bindValue(":patient_id", $old_patient_id);
$appAddStmt->bindValue(":date_app", $date_app);
$appAddStmt->bindValue(":time_app", $time_app);
$appAddStmt->bindValue(":reason", $reason);
$appAddStmt->execute();
echo "added";
}
else
{
echo "not added";
header("Location: add_appoint.php");
}
}
catch(PDOException $m)
{
$m->getMessage();
echo "error";
header("Location: add_app_btnoint.php");
}
}
}
?>
而且这里的HTML表单：
<form class="form-horizontal" id="add_app_form" onSubmit="return validate(this);">
<div class="box-body">
<div class="form-group">
<label for="patient_name" class="col-sm-3 control-label">Old Patient</label>
<div class="col-sm-4">
<select id="select_old" name="select_old">
<option value="choose">Choose Name</option>
<?php foreach($name_array as $na) { ?>
<option value="<?php echo $na['id'] ?>"><?php echo $na['patient_name'] ?></option>
<?php } ?>
</select>
</div>
<label for="patient_name" class="col-sm-1 control-label">New</label>
<div class="col-sm-4">
<input type="text" class="form-control" id="patient_name" name="patient_name" placeholder="New Patient Name">
</div>
</div>
<div class="form-group">
<label for="app_date" class="col-sm-2 control-label">Date</label>
<div class="col-sm-4">
<input type="date" class="form-control" id="app_date" name="app_date">
</div>
<label for="app_time" class="col-sm-2 control-label">Time</label>
<div class="col-sm-4">
<input type="time" class="form-control" id="app_time" name="app_time">
</div>
</div>
<div class="form-group">
<label for="app_reason" class="col-sm-2 control-label">Reason</label>
<div class="col-sm-10">
<textarea class="form-control" id="app_reason" name="app_reason" placeholder="Reason"></textarea>
</div>
</div>
</div><!-- /.box-body -->
<div class="box-footer">
<button type="submi;" id="add_app_btn" class="btn btn-success pull-right">Add Appointment</button>
</div><!-- /.box-footer -->
</form>
PS
值可以在URL中可以看到，但页面只是刷新没有添加任何东西
http://stackoverflow.com/questions/1053424/how-do-i-get-php-errors-to-display请阅读并告诉我们错误代码。 –
ajax代码在哪里？你有没有试过'print_r（$ _ POST）'？ –
而btw - 'add_app_btn'是一个'id'。它没有传递给服务器。 –
