DISPLAYING THE FIRST X CHARACTERS IN A WYSIWYG FIELD ON A LISTING PAGE - May 8th, 2011
|
User Deborah had this challenge.
She said:
I am (trying to use) a cutText function to limit the number of characters in a WYSIWYG field. Because the WYSIWYG
content automatically generates a closing </p> tag, I am unable to append a dot leader and "more" link such as this at
the end of the snipped text:
<p>WYSIWYG content blah, blah, blah ... <a href="<?php echo $record['_link']; ?>”>Read More</a>></p>
The first step in using cutText is to define the function in the head section of your viewer.
<?php function cutText($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 $string; }
?>
But when Deborah tried to implement the cutText function and preg_replace to accomplish her goal, it resulted in this
code:
<?php echo cutText($record['my_field']= preg_replace("|</p>\s*$|i", "...</p>", $record['my_field'] ), 90); ?>
but that did not work consistently.
Chris Waddell from Interactive Tools said:
Using the cutText() function (in this way) is (sometimes) stripping off the </p>. With no </p>, the preg_replace()
can't find the right place to add the ...
For consistency, I'd recommend stripping the </p> off first, then calling cutText(), then adding your read more link,
and finally replacing the </p> using the following code in the foreach loop:
<?php
$html = preg_replace("|</p>\s*$|i", "", $record['my_field'] );
$html = cutText($html, 90);
$html = $html . "...</p>";
echo $html;
?>
