Technique #1: Simple
function myTruncate($string, $limit, $break=".", $pad="...") {
if(strlen($string) <= $limit) return $string;
if(false !== ($breakpoint = strpos($string, $break, $limit))) {
if($breakpoint < strlen($string) - 1) {
$string = substr($string, 0, $breakpoint) . $pad; }
} return $string;
}
Technique #2: Simple
function ellipsis($text, $max=100, $append='…') {
if (strlen($text) <= $max) return $text;
$out = substr($text,0,$max);
if (strpos($text,' ') === FALSE) return $out.$append;
return preg_replace('/\w+$/','',$out).$append;
}
Usage:
<?php
$text = "Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum tortor quam, feugiat vitae, ultricies eget, tempor sit amet, ante. Donec eu libero sit amet quam egestas semper. Aenean ultricies mi vitae est. Mauris placerat eleifend leo.";
echo ellipsis($text,100);
?>
Technique #3: More Options
Options to use PHP’s php_tidy to fix up broken HTML, or to strip HTML entirely.
function summarise( $input, $break = " ", $end_text = "...", $limit = 255, $tidy_html = 1, $strip_html = 0 ) {
if ( strlen( $input ) >= $limit ) {
$breakpoint = strpos( $input, $break, $limit );
$input = substr( $input, 0, $breakpoint ) . $end_text;
}
if ( $tidy_html == 1 ) {
ob_start( );
$tidy = new tidy;
$config = array( 'indent' => true, 'output-xhtml' => true, 'wrap' => 200, 'clean' => true, 'show-body-only' => true );
$tidy->parseString( $input, $config, 'utf8' );
$tidy->cleanRepair( );
$input = $tidy;
}
if ( $strip_html == 1 ) {
$input = strip_tags( $input );
}
return $input;
}
Technique #4: Without a function
<?php
$long_text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";
$max_length = 40; // we want to show only 40 characters.
if (strlen($long_text) > $max_length)
{
$short_text = (substr($long_text,0,$max_length-1)); // make it $max_length chars long
$short_text .= "..."; // add an ellipses ... at the end
$short_text .= "<a href='http://example.com/page.html'>Read more</a>"; // add a link
echo $short_text;
}
else
{
// string is already less than $max_length, so display the string as is
echo $long_text;
}
?>
I’m using
<?php the_tags('','',''); ?>
to output tags. But where I keep it in my theme it may break if it’s a really long tag. How can I keep the single tags under a certain amount of letters and add ellipses at the end?
Looks like that is a WordPress function. You might want to try using get_the_tags() instead of the_tags(). The Get version will return an array instead of echoing the results. Then you can truncate the strings in the array before outputting.
Ciao Simon, Sorry for the unconventional point of contact. I just wanted to say that if you look for Belvedere Villa Mezzomonte on HomeAway and you contact me there, you don’t have to pay guests fees, which should cut a good 10% off your rate. Thanks, Davide
Thanks I’ll try that. Very helpful!
Used the first one :)
Thanks, very helpful
I stopped reading when i saw
if(false !==
Thanks, Chris.
