#184775

Hi,

i like to restrict the introtext. I use the field in k2 kategorie, but in the homepage are many categorys. And the introtext is not to restrict.

My idea is to rextrict the fild introtext with maxlength. I search in itemform, but i cant find the form for introtext.

Is there a chance to restrict it?

THX:-[

Hi syntom,

You can limit the intro text by using this modify function templatesja_walltemplate_tools.php

This will work with JA Wall 1.0.7.

public static function extractFirstParagraph($text, $limit = 50){
static $regex = '#<p[^>]*>(.*)</p>#i';
static $allowtag = '<a><b><strong><br>';

$result = '';
if (preg_match_all ($regex, $text, $matches)) {
$p = array();
$c = 0;
$cl = 50;

if($limit > 0){
$cl = $limit;
}

foreach ($matches[1] as $match) {
$t = trim(strip_tags ($match, $allowtag));
if ($t){
$l = strlen($t);
if ($limit > 0 && $c + $l >= $cl){
$w = JString::strpos($t, ' ', $cl - $c);
if($w === false){
$w = $cl - $c;
}

$t = JString::substr($t, 0, $w) . ($cl - $c < $l ? '...' : '');
$l = $cl - $c;
}

$p[] = $t;

$c += $l;
if($c >= $cl){
break;
}
}
}
$t = implode ('<br/>', $p);

$result = (strlen($t) > 7) ? $t : trim(strip_tags ($text, $allowtag));
} else {
$result = trim(strip_tags ($text, $allowtag));
}

return $result;
}

<blockquote>$limit = 50</blockquote>
Please change this number in the function for the maxlength of intro text show in wall block.

Regards

Hi sokakis,

Please make sure you clear the system cache and browser cache.
You can also pm the information (url/admin) of your site for me to check.

Ok i fixed it from k2 source. What you suggested didn’t work because i used an other editor with clean code on.
For those who want to use it change from ja_wall/html/k2/ja_wall/category_item.php.
find (line 163)
[PHP]<?php if($this->item->params->get(‘catItemIntroText’)): ?>
<?php echo $introtext; ?>
<?php endif; ?>[/PHP]

change to
[PHP]<?php if($this->item->params->get(‘catItemIntroText’)): ?>
<?php echo K2HelperUtilities::wordLimit($this->item->introtext, 50); ?>
<?php endif; ?>[/PHP]

Hi sokakis,

It is good that you happy with your solutions.
For $introtext variable, we have extract the intro text with pure text in there.
The $this->item->introtext may contains some tag which may load and cause unexpected result. (though it is rarely :laugh:)

Your way is better but not working with jck editor… work only with tinyMCE (tested)

Hi,

You just need to add ‘s’ in the regular expression.

Here the modify if you like my solution.

static $regex = '#<p[^>]*>(.*)</p>#is';
