无法url编码字符串

Question

当我输入时：

<form method="post"  action="../Thread/thread.php?threadID=".<?php echo $threadID; ?>."&page=".<?php echo $page; ?> > 

我明白了：

http://localhost/PoliticalForum/Thread/thread.php?threadID=

如何将变量编码到url中以避免出现此类错误？

Answer 1

 echo('<form method="post"  action="../Thread/thread.php?threadID=' . $threadID . '&page='  . $page . '">'); 

你的报价有问题。

编辑：

$url = sprintf("../Thread/thread.php?threadID=%1s&page=%2s",$threadID,$page);
echo('<form method="post"  action="'.$url .'">');

Answer 2

报价问题试试这个

<form method="post"  action="../Thread/thread.php?threadID=<?php echo $threadID; ?>&page=<?php echo $page; ?>" >

Answer 3

你的报价错了，试试这个：

<form method="post"  action="../Thread/thread.php?threadID=<?php echo $threadID; ?>&page=<?php echo $page; ?>">
