如何使用 .htaccess 重写 URL

Question

I am trying to re-write:

news.php?q=Contact+form+with+attachment

to look like:

news/Contact+form+with+attachment

my link looks like this

<a href="news/'.urlencode($row['title']).'">

and appears like this

http://localhost/untitled/public_html/news/Contact+form+with+attachment

in my news.php file , I have this code at the top

<?php $id = urldecode($_GET['q'])
$id = preg_replace('#[^0-9a-zA-Z]#i','',$id);
     $query = "SELECT * FROM news WHERE title = :id" ?>;

then in my .htaccess I wrote this

RewriteRule ^news/([0-9a-zA-Z_%+-]+) news.php?q=$1 [NC,L]

But when I click on the link it doesn't work it shows an empty/blank page please help thanks

Answer 1

it looks like you might be getting a white blank page because of a missing ; in your php at the end of this line <?php $id = urldecode($_GET['q'])

I don't know if that's your whole problem, but start by adding that like this:

<?php 
  $id = urldecode($_GET['q']);
  $id = preg_replace('#[^0-9a-zA-Z]#i','',$id);
  $query = "SELECT * FROM news WHERE title = :id" ?>;

Answer 2

The first variable $id wasn't correctly closed. Maybe the page is returning an empty or blank space because it's a fatal error. Change your code for this:

<?php 
$id = urldecode($_GET['q']);
$id = preg_replace('#[^0-9a-zA-Z]#i','',$id);
$query = "SELECT * FROM news WHERE title = :id";
?>

Sorry for my english.
