[myranieParticipant]

Hi everyone

Well , I have follow the tutorial for the Build A Blog script , and everything is perfect , except one thing , when we go on the index.php , when we click on ” Leave a comment ” I got this :

Invalid ID specified.

And the url don’t show the ID of the entry.

Well , I want some help to fix this

Here’s the url ( it’s a demo url , it’s just or testing everything before ) : http://oasis-designs.net/newblog/

Thank you very much for your help

Myranie

The post IDs are not currently being passed to the Leave a Comment link – if you look at the html it looks like this: your-url/newblog/entry.php?id=

Can you post the code you’re using for index.php? (Remove any passwords)

Here’s the code :

<?php

mysql_connect ('localhost', 'mymy_blog', '') ;

mysql_select_db ('mymy_blog');



$sql = "SELECT * FROM php_blog ORDER BY timestamp DESC LIMIT 5";



$result = mysql_query($sql) or print ("Can't select entries from table php_blog." . $sql . "" . mysql_error());



while($row = mysql_fetch_array($result)) {



$date = date("l F d Y", $row['timestamp']);



$title = stripslashes($row['title']);

$entry = stripslashes($row['entry']);



?>



<p><strong><?php echo $title; ?></strong>



<?php echo $entry; ?>



<?php



$result2 = mysql_query ("SELECT id FROM php_blog_comments WHERE entry='$id'");

$num_rows = mysql_num_rows($result2);



if ($num_rows > 0) {

echo "<a href="entry.php?id=">" . $num_rows . " comments</a>";

}

else {

echo "<a href="entry.php?id=">Leave a comment</a>";

} ?>



<hr /></p>



<?php

}

?>

The part where you echo Leave a comment is interpreted as HTML, and I see it like:

echo "<a href="entry.php?id=">Leave a comment</a>";

It should be something like:

echo "<a href="entry.php?id=$id">Leave a comment</a>";

Incidentally, I don’t see you initialize the $id variable anywhere. In which case its value is NULL so it wouldn’t show up in the HTML link’s src (hence your problem).

Instead of just:

$title = stripslashes($row['title']);

$entry = stripslashes($row['entry']);

have:

$title = stripslashes($row['title']);

$entry = stripslashes($row['entry']);

$id = $row['id'];

Hey!

Let me start off by saying thank you sooo much for your Build a Blog tutorial. You guys are amazing but I had a little bit of a hard time following the commenting process.

So! here goes:

I’m also having a ‘leave a comment’ problem but pretty sure it’s not the same thing that Myranie was having.

heres a really crappy start at my blog:

Non-working blog

I click ‘leave a comment’ and it just stays there. I know I must be missing something huge but I just don’t know!!!

What do you mean ‘it just stays there’? Moreover, when I click the Leave a comment button, it takes me to the edit comment page, not the comment page itself.
