Question

I’m trying to create commenting system with multiple pages (each page has its own comments).
For example – two pages for visitors: alegro.php and darwin.php

alegro.php

<?php 
$page="alegro"; // this variable should identify a page
include "comments.php";
?>

darwin.php

<?php 
$page="darwin";
include "comments.php";
?>

comments.php has a commentForm and some js validation code.
Then comments.php send all to the fourth file – submit.php, which populates dbTable:

mysql_query("INSERT INTO comments(page,name,url,email,body) VALUES (
      '$page' // - this is my first try
       $page  // - the second try
'".$arr['page']."' //the third try (after implementing a hidden "page" field into the form).
'".$arr['name']."',
'".$arr['url']."',
'".$arr['email']."',
'".$arr['body']."'
)");

Anyway – $page value is not written into the table.

Answer 1

darwin.php

$page = 'darwin';
include('comments.php');

comments.php

<form action="submit.php">
    <input type="hidden" name="page" value="<?php echo $page; ?>" />
    <textarea name="comment"></textarea>
</form>

submit.php

// $arr array filled
$arr['page'] = $_REQUEST['page'];
mysql_query("INSERT INTO comments(page,name,url,email,body) VALUES (
    '".$arr['page']."',
    '".$arr['name']."',
    '".$arr['url']."',
    '".$arr['email']."',
    '".$arr['body']."'
    )");

FYI – don’t use mysql_* as it’s being deprecated. Switch to PDO or mysqli functions.
