使HTML文件中的变量在PHP文件中工作 [英] Making variable from HTML-file work in PHP-file
问题描述
我有两个非常简单的文件.第一个是这样的HTML文件:
I have two rather simple files. The first is an HTML-file like this:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<html>
<body>
<form action="test.php" method="post">
Search for: <input type="text" name="search" />
<input type="submit" name="submit" value="Search" />
</form>
</body>
</html>
第二个文件是test.php，它看起来像这样:
The second file is test.php and it looks like this:
<?
$filepath = "/usr/sbin";
exec("ONE $search -command $filepath ");
fopen($filepath, rw);
?>
我的问题是我想使用HTML表单中给出的参数搜索"作为PHP脚本中变量的值.一个是我制作的带有一个参数的搜索脚本，我希望它是"$ search".
My problem is that I want to use the argument "search" given in the HTML-form as value of variable in the PHP-script. ONE is a search script I made that takes one argument and I want it to be "$search".
可以这样做吗?如果可以，怎么办?
Could this be done and if so how?
非常感谢.
推荐答案
只需执行以下操作:
exec("ONE " . $_POST['search']. " -command $filepath ");
更新:
您在下一行中遇到另一个错误:
UPDATE:
You have another error, your following line:
fopen($filepath, rw);
应该是这样的:
fopen($filepath, "rw");
因为fopen()的第二个参数应作为字符串传递.
cause the second parameter to fopen() should be passed as a string.
更新2 :
如此看来，OP希望将命令的输出打印在页面上，因为您必须使用 passthru()代替exec()，就像这样:
UPDATE 2:
So as it seems, the OP want the output of the command to be printed on the page, for that you have to use passthru() instead of exec() , like so:
passthru("ONE " . $_POST['search']. " -command $filepath ");
