Let's开发者_JAVA技巧 say I have a form with two input fields, title and comment. After the user fills the two fields and submits the data, a page is automatically created that contains the title and comment that the user typed, in a folder located in root directory, for example, www.root.com/page/ will contain the automatically generated page.

Update:

I'd like the form data to be sent to an SQL table row with the url of the auto-generated page to be in the same SQL row as the title and comment.

How do I do this via PHP?

<?php
//Template for basic page
$template = <<<EOD

<title><!--TITLE--></title>

<body>
<!--COMMENT-->
</body>
</html>
EOD;

//handle the posted form
if(isset($_POST['title'])&&isset($_POST['comment'])){
    //replace the areas of the template with the posted values
    $page = str_replace('<!--TITLE-->',htmlentities($_POST['title']),$template);
    $page = str_replace('<!--COMMENT-->',htmlentities($_POST['comment']),$page);
    //create a name for the new page
    $pagename = md5($_POST['title']).'.html';

    //db connect & select
    $db=mysql_connect('localhost','user','pass');
    mysql_select_db('yourdb');

    //check if page already exists
    $result = mysql_query('SELECT pagename from yourtable WHERE url="'.mysql_real_escape_string($pagename).'"');
    if(mysql_num_rows($result)>=1){
        $notice = '<p>Page already created <b>./pages/'.$pagename.'</b></p>';
    }else{
        //inset new page into db
        mysql_query('INSERT into yourtable (`id`,`title`,`comment`,`url`)VALUES("",
        "'.mysql_real_escape_string(htmlentities($_POST['title'])).'",
        "'.mysql_real_escape_string(htmlentities($_POST['comment'])).'",
        "'.$pagename.'")');
        //put the created content to file
        file_put_contents('./pages/'.$pagename,$page);
        //make a notice to show the user
        $notice = '<p>New Page created <b>./pages/'.$pagename.'</b></p>';
    }
}
?>
