php - 在 php 代码中使用 wml 变量

Question

我写了以下代码

<?xml version="1.0" ?>
<wml>
<card>
 title : <input type="text" name="title" /><br/>
 body : <input type="text" name="body" /><br/>
<?php 
echo $(title)
?>
</card>
</wml>

问题我如何在 php 代码中的输入文本中打印输入的值。

Answer 1

首先，如果您希望输入字段执行任何操作，您需要在标记中定义一个表单。表单应该有一个action和一个method属性。

然后您可以使用$_GET或$_POST超全局数组以下列方式访问数据：

echo $_POST['title'];

Answer 2

If you want to print the content of a variable directly in the screen of the device (or printer if it is an extended WML browser) you need to do it like this:

$(varName)

In your sample you are setting the value from a server variable, not from the device's memory.

A bit late answer but may help someone, WML is not so common anymore but still it is being used for banking and other kind of automated dispensers.
