将变量从PHP传递到HTML [英] Pass variable from PHP to HTML

问题描述

我有一个页面， play.html ：

 < ; form method =postaction =play.php> 
< input type =hiddenname =mp3namevalue =/ MP3 / 1.mp3> 
< input type =submitvalue =Play My MP＃＃1/> 
< / form> 
 
 
< form method =postaction =play.php> 
< input type =hiddenname =mp3namevalue =/ MP3 / 2.mp3> 
< input type =submitvalue =Play My MP＃＃2/> 
< / form> 
  

这会调用另一个页面， play.php ：

 <？php 
 
 $ formurl =play.html; 
 $ playerurl =player.html; 
 
 $ mymp3 = $ _GET [mp3name]; 
 
 header（Location：$ playerurl？mp3name = $ mymp3）; 
出口; 
？> 
  

然后调用另一个页面< player.html ：

 < audio id =playersrc =$ mymp3autoplay preload =auto> < /音频> 
< div> 
< button onclick =document.getElementById（'player'）。play（）>播放< / button> 
< button onclick =document.getElementById（'player'）。pause（）>暂停< /按钮> 
< button onclick =document.getElementById（'player'）。volume + = 0.1>增大音量< /按钮> 
< button onclick =document.getElementById（'player'）。volume- = 0.1> Volume Down< / button> 
< / div> 
  

如何将一个变量从PHP传递给 player.html

解决方案

您正在获取 $ mymp3 在使用< form method ='post'.. 时将 $ _ GET 更改为;

然后，将您的player.html扩展名更改为player.php以使用PHP代码就可以了。

所以，当你有你的player.php文件时，改变这个...

 < audio id =playersrc =$ mymp3autoplay preload =auto> < /音频> 
  

至此...

 < audio id =playersrc =<？php echo $ mymp3？> autoplay preload =auto> < /音频> 
  

I have a page, play.html:

    <form method="post" action="play.php">
         <input type="hidden" name="mp3name" value="/MP3/1.mp3">
         <input type="submit"  value="Play My MP# #1" />
    </form>


<form method="post" action="play.php">
    <input type="hidden" name="mp3name" value="/MP3/2.mp3">
    <input type="submit"  value="Play My MP# #2" />
</form>

This calls another page, play.php:

<?php

$formurl = "play.html" ;
$playerurl = "player.html" ;

$mymp3 = $_GET["mp3name"]; 

header( "Location: $playerurl?mp3name=$mymp3" );
exit ;
?>

Then it calls another page, player.html:

<audio id="player" src="$mymp3" autoplay preload="auto"> </audio>
       <div>
       <button onclick="document.getElementById('player').play()">Play</button>
       <button onclick="document.getElementById('player').pause()">Pause</button>
       <button onclick="document.getElementById('player').volume+=0.1">Volume Up</button>
       <button onclick="document.getElementById('player').volume-=0.1">Volume Down</button>
          </div> 

How do I pass a variable from PHP to player.html?

解决方案

You are getting the variable $mymp3 with $_GET while you are using <form method='post'.., change it to $mymp3 = $_POST['mp3name'];

Then, change your player.html extension to player.php to use PHP code on it.

So, when you have your player.php file, change this...

<audio id="player" src="$mymp3" autoplay preload="auto"> </audio>

to this...

<audio id="player" src="<?php echo $mymp3 ?>" autoplay preload="auto"> </audio>
