Truncating Latest Posts
-
Hi, I’m having an issue with my front page. I’m finding that my users might want to post particularly long articles. It wouldn’t be a problem, except that I can’t seem to figure out how to have their front page posts cut off after a certain number of words and display something like “Read More…”
Has anyone ran into a problem like this? Surely it’s something simple. I’m not sure if it’s an option somewhere in the BuddyPress Dashboard, or if I can download a plugin that can do something like that. I’m not sure where to look
Thanks for any help.

You can definitely limit posts by character count as they’re being inserted. Find where the post form is in your template. I’m using this in Buddypress for the activity stream, so I’m not sure if it’s the same for the regular WP postings. But you should be able to work it around a little bit:
`
function limitChars(textarea, limit, infodiv)
{
var text = textarea.value;
var textlength = text.length;
var info = document.getElementById(infodiv);if(textlength > limit)
{
info.innerHTML = ‘You cannot write more than ‘+limit+’ characters!’;
textarea.value = text.substr(0,limit);
return false;
}
else
{
info.innerHTML = ‘You have ‘+ (limit – textlength) +’ characters left.’;
return true;
}
}Maximum 500 characters.
`
You can put that code right before
`
Also of note, if you’re doing an AJAX submit that doesn’t refresh the page, you’ll want to have an onclick action set on the submit button that re-inserts the original HTML of the ‘whatsleft’ span back into it. Otherwise they’ll still see the number of characters they had left when they submitted it, even though the form is blank.
Note: I didn’t write this js, I found it somewhere. Possibly on these forums…but it works
