我将变量从我的 Flash MP3 播放器传递到 PHP 脚本以记录播放的歌曲。现在我希望 PHP 脚本显示一个变量并将其包含在 Amazon 链接中。

这就是我所拥有的，但似乎无法让它发挥作用。

<?php
$var1  = $_POST['var1']; //get the Artist Name and Title from Flash and store it in a PHP variable
$var2 = $_POST['var2']; //ignored
//This lines combines the two variables into one string. 
//To concatinate vars in PHP use a period or dot ".", much like Flash uses a plus sign "+". 

$add = $var1 . "+" . $var2 . "|";
//opens or creates (if it doesn't already exist) our text file (songsplayed.txt) 
//for writing (not reading) and places the pointer at the end.
$open = fopen('songsplayed.txt', 'a'); 
//writes to our specified file our string
$write = fwrite($open, $add); 

echo $var1;
echo

<a type="amzn" search=\"$var1\" category="music">
<img border="0" src="/buttons/buy-now-button-amazon.png" alt="Buy now @ Amazon"></a>
?>

您似乎试图将 HTML 回显到页面而不用引号括起来。试试这个：

<?php
$var1  = $_POST['var1']; //get the Artist Name and Title from Flash and store it in a PHP variable
$var2 = $_POST['var2']; //ignored
//This lines combines the two variables into one string. 
//To concatinate vars in PHP use a period or dot ".", much like Flash uses a plus sign "+". 

$add = $var1 . "+" . $var2 . "|";
//opens or creates (if it doesn't already exist) our text file (songsplayed.txt) 
//for writing (not reading) and places the pointer at the end.
$open = fopen('songsplayed.txt', 'a'); 
//writes to our specified file our string
$write = fwrite($open, $add); 

echo $var1;
?>
<a type="amzn" search="<?php echo $var1; ?>" category="music">
<img border="0" src="/buttons/buy-now-button-amazon.png" alt="Buy now @ Amazon"></a>

你可以试试这个；

<?php
// minimal xss protection
$var1 = htmlentities($_POST['var1'], ENT_QUOTES, 'UTF-8');
$var2 = htmlentities($_POST['var2'], ENT_QUOTES, 'UTF-8');
// one-line append
file_put_contents('songsplayed.txt', sprintf("%s+%s\r\n", $var1, $var2));
// proper echo'ing
echo $var1,
     '<a type="amzn" search="'. $var1 .'" category="music">',
     '<img border="0" src="/buttons/buy-now-button-amazon.png" alt="Buy now @ Amazon"></a>';
?>
