I have 2 features that I would like to have on my blog, but don't know how to add them:
1. I want to limit the number of characters displayed for each post on the main page and a link that says, "read more" that will take the reader to the single entry page
2. A link on the main page to next 5 older posts
Thanks!

Okay, before I say anything else: I remember seeing this in another thread and making a mental note (for possible future use). So I took a chance and gave it a whirl, hoping I could be of some assistance with your first request.
You can truncate the number of characters in your post using the substr() function. Using Jenny's example, I added the part that trims the post length after the variables:
Basically, the code is saying if the string length of the entry is more than 90 characters, only display the first 90 characters, followed by "..." and a link to the single entry page.
Of course you can set whatever number you like (90 is pretty small) and format the link however you please.
In the post I linked to, there's an example of how to cut off after a certain number of words, but I haven't tried it.
I hope this helps! If it goes all wonky instead, I'm positive someone with more knowledge than I will chime in to help us out

Hey that did exactly what I wanted! Thanks a lot!
If anyone can help me out with the code to the next 5 older entries, I would appreciate it!
Thanks
Where would that code go, echolalia?

Steven,
Open up the main page of your blog, find the following code:
CODE
$title = stripslashes($row['title']);
$entry = stripslashes($row['entry']);
$password = $row['password'];
$id = $row['id'];
$entry = stripslashes($row['entry']);
$password = $row['password'];
$id = $row['id'];
And beneath that paste this code:
CODE
if (strlen($entry) > 90)
{
$entry = substr($entry,0,90);
$entry = "$entry... <br /><br /><a href=\"journal.php?id=" . $id . "\">read more</a>";
}
{
$entry = substr($entry,0,90);
$entry = "$entry... <br /><br /><a href=\"journal.php?id=" . $id . "\">read more</a>";
}
There you go!
btw I'm still looking for an answer to the other part of my question!
For the next five older posts, you will need to implement pagination. Here is just one of many tutorials on how to do it.
Thanks tjs, I'll try that!
Amelie, thanks for the link!
EDIT: I'm not quite sure how to implement that into my blog...
