我对联系方式有一个很大的问题。 我已经很长时间试图获得表格并运行whit php。 我还有一个验证码功能，我现在正在查看。
但我需要帮助惠特形式和PHP部分： 1.检查所有表单字段并在输入字段不正确时给出错误消息（右侧是输入字段的红色）。 2.如果检查表单字段后一切正常，则发送电子邮件。并且发出电子邮件已发送的消息。
contactform.php
public class ArrivalRecord {
final StringProperty bid;
final StringProperty firstName;
final StringProperty lastName;
final StringProperty arrival;
final StringProperty checkout;
final StringProperty roomNumber;
final StringProperty roomType;
final StringProperty nights;
final StringProperty breakfast;
final StringProperty amount;
final StringProperty comment;
ArrivalRecord(String bid, String firstName, String lastName,
String arrival, String checkout, String roomNumber,
String roomType, String nights, String breakfast,
String amount, String comment) {
this.bid = new SimpleStringProperty(bid);
this.firstName = new SimpleStringProperty(firstName);
this.lastName = new SimpleStringProperty(lastName);
this.arrival = new SimpleStringProperty(arrival);
this.checkout = new SimpleStringProperty(checkout);
this.roomNumber = new SimpleStringProperty(roomNumber);
this.roomType = new SimpleStringProperty(roomType);
this.nights = new SimpleStringProperty(nights);
this.breakfast = new SimpleStringProperty(breakfast);
this.amount = new SimpleStringProperty(amount);
this.comment = new SimpleStringProperty(comment);
}
public String getBid() {
return bid.get();
}
public String getFirstName() {
return firstName.get();
}
public String getLastName() {
return lastName.get();
}
public String getArrival() {
return arrival.get();
}
public String getCheckout() {
return checkout.get();
}
public String getRoomNumber() {
return roomNumber.get();
}
public String getRoomType() {
return roomType.get();
}
public String getNights() {
return nights.get();
}
public String getBreakfast() {
return breakfast.get();
}
public String getAmount() {
return amount.get();
}
public String getComment() {
return comment.get();
}
public StringProperty getBidProperty() {
return bid;
}
public StringProperty getFirstNameProperty() {
return firstName;
}
public StringProperty getLastNameProperty() {
return lastName;
}
public StringProperty getArrivalProperty() {
return arrival;
}
public StringProperty getCheckoutProperty() {
return checkout;
}
public StringProperty getRoomNumberProperty() {
return roomNumber;
}
public StringProperty getRoomTypeProperty() {
return roomType;
}
public StringProperty getNightsProperty() {
return nights;
}
public StringProperty getBreakfastProperty() {
return breakfast;
}
public StringProperty getAmountProperty() {
return amount;
}
public StringProperty getCommentProperty() {
return comment;
}
}
Send_form_email.php 如果我使用它，此代码正常工作：
然后用户被迫远离表单。 并且所有错误消息都在空白的php页面上给出，而不是以验证码的形式给出。
<?php session_start();
if (isset($_POST['Submit'])) {
if (empty($_POST["first_name"])) {
$nameError = "Name is required";
}
else {
$name = test_input($_POST["first_name"]);
// check name only contains letters and whitespace
if (!preg_match("/^[a-zA-Z ]*$/",$name)) {
$nameError = "Only letters and white space allowed";
}
}
// code for check server side validation
if(empty($_SESSION['6_letters_code'] ) || strcasecmp($_SESSION['6_letters_code'], $_POST['6_letters_code']) != 0){
$msg="<span style='color:red'>The Validation code does not match!</span>";// Captcha verification is incorrect.
}else{// Captcha verification is Correct. Final Code Execute here!
$msg="<span style='color:green'>The Validation code has been matched.</span>";
}
}
?>

Send_email_form.php
答案 0 :(得分：0)
这是因为您正在使用此if语句。
if(strlen($error_message) > 0) {
died($error_message);
}
如果要在实际联系表单上显示错误消息。你需要使用
// Send_email_form.php中的更改
if(strlen($error_message) > 0)
{
header('Location: contactform.php?err='.$error_message);
exit;
}
//更改contactform.php - 使用这段代码在页面上显示错误。
if(isset($_GET['err']) && !empty( $_GET['err'] )
{
echo $_GET['err'];
}
