Question

我正在尝试完成一项任务。我需要打印@Component public class DepartmentEditor extends PropertyEditorSupport{ @Autowired DepartmentService depService; @Override public String getAsText() { return super.getAsText(); } @Override public void setAsText(String value) throws IllegalArgumentException { if(value.isEmpty()){ try { Department dep = depService.findById(Integer.parseInt(value)); if (null!=dep) { setValue(dep); } else { throw new IllegalArgumentException("Binding error. Cannot find userAccount with id ["+value+"]"); } } catch (NumberFormatException e) { throw new IllegalArgumentException("Binding error. Invalid id: " + value); } } else { setValue(null); } } }（下面指定）。但它不打印我不知道什么似乎是问题。我提前感谢你的帮助......我不想在html代码中做这个echo $ message的事情。有一点你应该知道值是在echo $message之前打印的。 php变量在echo $message之前有值，但是当我回显$message时，这些相同的变量什么都不打印..它只打印

客户名称：

客户电邮：

客户手机：

客户城市：

客户结算地址：

$message

HTML文件：

       <?php
if(isset($_POST['sub'])){

    $name=$_POST['name'];
    $email=$_POST['email'];
    $mobile=$_POST['mobile'];
    $city=$_POST['city'];
    $bill_add=$_POST['message'];
   echo $message="
     <html><head> </head>

      <body>
       Customer Name: <?php echo  $name; ?>
       <br>
          Customer Email: <?php echo $email; ?>
        <br>
         Customer Mobile: <?php echo $mobile; ?>
       <br>
        Customer City: <?php echo $city; ?>
      <br>
    Customer Billing Address: <?php echo .$bill_add; ?>
    </body></html>";}
      ?>

Answer 1

将您的$message更改为：

 echo $message="
     <html><head> </head>

      <body>
       Customer Name: $name
       <br>
          Customer Email: $email
        <br>
         Customer Mobile: $mobile
       <br>
        Customer City: $city
      <br>
    Customer Billing Address: $bill_add
    </body></html>";}
      ?>

问题在于您将<?php echo用于<?php echo

Answer 2

尝试：

<?php
if(isset($_POST['sub'])){

    $name=$_POST['name'];
    $email=$_POST['email'];
    $mobile=$_POST['mobile'];
    $city=$_POST['city'];
    $bill_add=$_POST['message'];
   echo "
     <html><head> </head>

      <body>
       Customer Name: ".$name."
       <br>
          Customer Email: ".$email."
        <br>
         Customer Mobile: ".$mobile."
       <br>
        Customer City: ".$city."
      <br>
    Customer Billing Address: ".$bill_add."
    </body></html>";}
      ?>

Answer 3

你无法使用

这样可以更好地使用它，在php中使用连接解决了你的问题。

<?php 
    echo $message="
     <html><head> </head>

      <body>
       Customer Name: ".$name."
       <br>
          Customer Email: ".$email."
        <br>
         Customer Mobile: ".$mobile."
       <br>
        Customer City: ".$city."
      <br>
    Customer Billing Address: ".$bill_add."
    </body></html>";
      ?>

Answer 4

 <?php   echo $message="<html><head> </head><body>Customer Name: " . $name . " <br>Customer Email: " . $email . " <br>Customer Mobile: " . $mobile . " <br>Customer City: " . $city . "<br>Customer Billing Address: " . $bill_add . " </body></html>";?>

//我们在这里使用连接（。）所以我们不需要编写和删除空格。

php值不打印
