Question

I currently have this:

<?php
  $con = mysql_connect('localhost', 'root', 'dev');
  if(!$con) {
    die('Could not connect: ' . mysql_error());
  }
  mysql_select_db("myDB");
  $query = "SELECT * FROM pages where id=1";
  $result = mysql_query($query);
  $row = mysql_fetch_assoc($result);
  $contents = $row['content'];
  echo $contents;
?>

See this part: SELECT * FROM pages where id=1

1 is the record id and it’s currently hardcoded. What I need to do is change it so it get’s the record id from the url…for example: mysite.com/index.php?2 would show record id 2 …

How do I go about doing this?

Answer 1

Turn that hardcoded value into a variable.

<?php
    //assumes you have a querystring like: http://mysite.com/index.php?id=3
    $id = $_GET['id'];


  $con = mysql_connect('localhost', 'root', 'dev');
  if(!$con) {
    die('Could not connect: ' . mysql_error());
  }
  mysql_select_db("myDB");


    //Make your variable safe for use with mysql
    $id = mysql_real_escape_string($id);
  $query = "SELECT * FROM pages where id=" . $id;
  $result = mysql_query($query);
  $row = mysql_fetch_assoc($result);
  $contents = $row['content'];
  echo $contents;
?>
