I beleive I might have ask about this before but I noticed there are php codes to limit the amount of text that is shown with out having to set it in the cms builder itself. The only problem I have is it cuts the words off. Here is the code, is there a way to change it to show the full word and not cut it off thanks.

<?php echo substr($record['content'], 0, 150);?>

Hi Glenn,

Often if you look in the comments on php.net for a function people will post other solutions for things like this.

Check out http://www.php.net/substr (just replace substr to look up any other function)

They have this one:

<?php

function cutText($string, $setlength) {
$length = $setlength;
if($length<strlen($string)){
while (($string{$length} != " ") AND ($length > 0)) {
$length--;
}
if ($length == 0) return substr($string, 0, $setlength);
else return substr($string, 0, $length);
}else return $string;
}

?>

Which you could use like this:

<?php echo cutText($record['content'], 0, 150); ?>

Hope that helps!

Thanks Dave. Where do I place the php function code.

<?php

function cutText($string, $setlength) {
$length = $setlength;
if($length<strlen($string)){
while (($string{$length} != " ") AND ($length > 0)) {
$length--;
}
if ($length == 0) return substr($string, 0, $setlength);
else return substr($string, 0, $length);
}else return $string;
}

?>

You can put it at the top of the page, or anywhere before you call cutText().

Dave it doesn't show any text. Do I need to change any of the "0" in the code?

Oh, yes you're right. Drop the 0, try this:

<?php echo cutText($record['content'], 150); ?>

Dave it works great thanks so much. One other question. If the content is shorter then the 150 limit it doesn't show anything. In that php function code is there a way to have it still show the content if it doesn;t meet the limit? Thanks again for your 100% customer support.

I'm not sure because I didn't write that function. You could check the comments or for other functions at the php.net link above.

Also, here's a function I wrote for Donna that limits by words:

// Usage: < ?php print maxWords($content, 25); ? >
function maxWords($textOrHtml, $maxWords) {
$text = strip_tags($textOrHtml);
$words = preg_split("/\s+/", $text, $maxWords+1);
if (count($words) > $maxWords) { unset($words[$maxWords]); }
$output = join(' ', $words);

return $output;
}

Maybe that one will work better?

That code works on the word count. So it shows the number of words you specify.
