Hello to all,

I want to print part of a post using (like the first 100 words) the vB_BbCodeParser. If I use PHP sometimes I cut thre string in the middle of somewhere where I should not and I cannot display the html correctly.

For example:



$bbcode_parser =& new vB_BbCodeParser(vb::$vbulletin, fetch_tag_list(), true);
$text= '
<div class="review-text">
&quot;'.substr($bbcode_parser->parse($opiniones["pagetext"]), 0, 400).'...<a href="threads/'.$opiniones["threadid"].'-'.urlencode($opiniones["thread_title"]).'?p='.$opiniones["postid"].'#post'.$opiniones["postid"].'">ver m?s</a>...&quot;

</div>

echo $text;





Here, the link does not work because I cut the code incorrectly.

<span style="font-fam...<a href="thr


Any ideas?

Is this for vB5? Looks likes not.

Anyway, why not let the browser (via CSS) truncate the text and add ellipsis (...) depending on how wide the container of the text is?

$bbcode_parser =& new vB_BbCodeParser(vb::$vbulletin, fetch_tag_list(), true);
$text= '
<div class="review-text">
&quot;<span class="pagetext h-inline-block ellipsis">' . $opiniones["pagetext"] . '</span><a href="threads/'.$opiniones["threadid"].'-'.urlencode($opiniones["thread_title"]).'?p='.$opiniones["postid"].'#post'.$opiniones["postid"].'">ver m?s</a>...&quot;
</div>
';
echo $text;
Then add this in additional css:
.review-text .pagetext { width: 90%; }
vB5 has helper css classes ellipsis and h-inline-block to easily make an element behave like a text with ellipsis.

In that case, remove the h-inline-block and ellipsis css classes in the span tag and then replace this css in additional css:

.review-text .pagetext { width: 90%; }

with:

.review-text .pagetext {
display: inline-block;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
width: 90%;
}
