character limit help

Help with WordPress
#1

I have a table on a WP site here http://www.rocktownhall.com/blogs/latest-comments-5 generated by a PHP based plugin. I have been able to tweak the comments.php file here-and-there with success but have not been able to make it display all characters or 1000 characters at least.

Help?

The comments are outputted in two different places. Here (line 140):
[php] if($options[‘excerpt’] == ‘on’) {
$exp = get_comment_excerpt();
echo ‘
’, ($options[‘smiles’] == ‘on’ ? convert_smilies($exp) : $exp);
}[/php]

And here (line 76):
[php] comment_text();[/php]

Both call Wordpress functions. In order:

  • get_comment_excerpt() will truncate your comment to the end of the sentence closest to the 20th word of your comment. There are no possible configuration parameters to this function, so you cannot modify it without modifying it inside Wordpress (or using runkit to override it).
  • comment_text() merely outputs the comment text in full.

If it’s the first one that is bothering you, you can use a slightly modified function of the second to get what you want. comment_text has a related shorthand function called get_comment_text() which behaves in exactly the same fashion - except that it returns instead of echoing.

A modification for the excerpt bit would be as follows:
[php] if($options[‘excerpt’] == ‘on’) {
$exp = get_comment_text();
echo ‘
’, ($options[‘smiles’] == ‘on’ ? convert_smilies($exp) : $exp);
}[/php]

Let me know if this was not what you were looking for!

sebrenauld- You are the man! It worked wonderfully. I needed to tighten some stuff up but used CSS and not it is looking and working great. Thank you so much. Thinking maybe I should get PHP for Dummies and dig in a bit.

I would not recommend PHP for dummies, actually. If you’re serious about learning PHP, get this book: http://shop.oreilly.com/product/9780596005603.do. It is far, far more explicative than PHP for dummies et al.

With the recommendation, you’ll also learn why you’re doing stuff the way you do it.
