Question

<>strong>SOLVED 感谢你的反馈! 非常感谢。

如果任何人都能够帮助解决简单的yn子问题,我会非常赞赏。我仍然处在学习阶段,而且现在似乎无法说明这一点。在以下法典中,我分配了一个阵列和一个定义,以便与它一起,但当我试图重复信息时,它却不发挥作用。

   $arr_features=array("PasswordProtect");

  $arr_FeaturesDescriptions = array("Password Protection: Password Protection will be enabled, requiring participants to enter a password in order to access the event. Your password is: "echo ($_POST[ PasswordProtect ]);"");

因此,基本上来说,“Your 密码是:”部分是徒劳的,任何想法为什么? 提前感谢。

Answer 1

由于你正在学习PHP:

echo() will output a string to the rendered HTML. If you want to append a string (generated or not) to another string s end, you need to concatenate them, using the concatenation operator, which is . in PHP (yes, a dot).

In your example, it becomes: $arr_FeaturesDescriptions = array("Password Protection: Password Protection will be enabled, requiring participants to enter a password in order to access the event. Your password is: " . $_POST[ PasswordProtect ]);

Answer 2

$arr_FeaturesDescriptions = array("Password Protection: Password Protection will be enabled, requiring participants to enter a password in order to access the event. Your password is: " . $_POST[ PasswordProtect ]);

Answer 3

因为你试图在扼杀中插入一句话。相反,正确的辛加税

  $arr_FeaturesDescriptions = array("Password Protection: Password Protection will be enabled, requiring participants to enter a password in order to access the event. Your password is: {$_POST[ PasswordProtect ]}");

Answer 4

为了在座标中产生一个变量,需要使用<代码>。

$arr_FeaturesDescriptions = array("Password Protection: Password Protection will be enabled, requiring participants to enter a password in order to access the event. Your password is: " . $_POST[ PasswordProtect ]);

或 brackets 括号{}:

$arr_FeaturesDescriptions = array("Password Protection: Password Protection will be enabled, requiring participants to enter a password in order to access the event. Your password is: {$_POST[ PasswordProtect ]}");

Answer 5

您应当从_POST中过滤数据,然后在你的代码中使用。由于你正在使用双重报价,你可以很容易地插入一种变式,因为购买力平价中的双报价将评价以下变量:

$passwordprotect = validate_input($_POST[ PasswordProtect ]);
$arr_features=array("PasswordProtect");
$arr_FeaturesDescriptions = array("Password Protection: ... Your password is: $passwordprotect");

但是,你真的应该说的是,不管怎么说,都不会出现一个简单的文字密码。

Answer 6

此处与,其中详细介绍了你在PHP中处理扼杀问题的不同方式。

Answer 7

$arr_features=array("PasswordProtect");
