如何在echo PHP函数中显示此HTML字符串 [英] How to display this HTML string in echo php function

问题描述

我是php的新手...我有一个将用户名变量传递给php scrit的表单，这是代码。.
< form action = bottone .php method = get>输入法：<输入名称=用户名 type =文本 /> <输入type = submit value = GENERA CODICE /> < / form>

I'm a newbie in php... I have a form who pass a username variable to a php scrit, this is the code.. <form action="bottone.php" method="get"> Inserisci il tuo nome utente: <input name="username" type="text" /> <input type="submit" value="GENERA CODICE" /> </form>

我想在botton.php脚本中显示以下HTML代码：

I would like to display this HTML code in the botton.php script:

<a href=www.mysite.com/$username <img src="http://www.mysite.com/images/logo.jpg" width="50" height="50" alt="La mia pagina su Mysite"/></a>

其中$ username是从表单传递的变量...我该如何用echo做到这一点功能？？
谢谢

where $username is the variable passed from the form... how can I do that with an echo function?? Thanks

推荐答案

像这样：

<?php
echo '<a href="http://www.mysite.com/'.$username.'"><img src="http://www.mysite.com/images/logo.jpg" width="50" height="50" alt="La mia pagina su Mysite"/></a>';
?>

或者，像这样：

<a href="http://www.mysite.com/<?=$username?>"><img src="http://www.mysite.com/images/logo.jpg" width="50" height="50" alt="La mia pagina su Mysite"/></a>

您可能需要确保$ username是安全的，但至少要使用 urlencode ， htmlspecialchars 或类似的内容。

You may want to make sure $username is safe though... at least use urlencode, htmlspecialchars, or something similar.

* EDIT > *
我假设您已经知道如何从您提到的表单中获取$ username，但是如果您不知道，则可以这样做：

*EDIT* I had assumed you already knew how to get $username from the form you mentioned, but in case you didn't, you would just do:

$username = $_GET['username'];

或者您可以以此为契机使用上面提到的那些功能（除非您需要

Or you could use this as an opportunity to use those functions I mentioned above (unless you will be needing $username for some other purpose before echoing it out.

示例：

$username = urlencode($_GET['username']);

或者您可以这样做直接在回声中像这样：

Or you could do this straight in the echo like this:

<a href="http://www.mysite.com/<?=urlencode($_GET['username'])?>"><img src="http://www.mysite.com/images/logo.jpg" width="50" height="50" alt="La mia pagina su Mysite"/></a>
