Setup Title, image and text automatically for article in home

paoloci

Hello
I use in the homepage 9 articles in 3 columns.
In which way I can reduce, only in home,
1 - the number of characters for title (for example 30 characters)
2 - the dimension of the first image (for example width 300px; height 200px😉
3 - the number of characters of the text? (for example 200 characters)

Thanks for suggestion

Hello
for the title I have tried to modify

blog_style_default_item_title.php

from

<?php echo $this->escape($displayData->title); ?>
to
<?php echo substr($this->escape($displayData->title), 0, 10)."..."; ?>

so:

<h2 itemprop="name">
<?php if ($params->get('link_titles') && ($params->get('access-view') || $params->get('show_noauth', '0') == '1')) : ?>
<a href="<?php echo JRoute::_(
ContentHelperRoute::getArticleRoute($displayData->slug, $displayData->catid, $displayData->language)
); ?>" itemprop="url">
<?php echo substr($this->escape($displayData->title), 0, 10)."..."; ?>
</a>
<?php else : ?>
<?php echo substr($this->escape($displayData->title), 0, 10)."..."; ?>
<?php endif; ?>
</h2>

	But the problem remain..

Hi paoloci

You can try this:

<?php echo substr(($this->item->title), 0, 30)."..."; ?>

First of all thanks for answer.
I have overwrite - also directly without the use of override, in doubt use a wrong path - this below with Your suggest

<h2 itemprop="name">
<?php if ($params->get('link_titles') && ($params->get('access-view') || $params->get('show_noauth', '0') == '1')) : ?>
<a href="<?php echo JRoute::_(
ContentHelperRoute::getArticleRoute($displayData->slug, $displayData->catid, $displayData->language)
); ?>" itemprop="url">
<?php echo substr(($this->item->title), 0, 30)."..."; ?>
</a>
<?php else : ?>
<?php echo substr(($this->item->title), 0, 30)."..."; ?>
<?php endif; ?>

blog_style_default_item_title.php

no good result.

Please see
[https://www.progettoautismo.it/]
(cache is often clean)

Am I in wrong? Where?
And also why is so difficult to obtain equal result with articles in home like a module (for example minifrontpage)?
Do you suggest I write in Joomla! developer session?

You edited the wrong file, it should be this one for Featured Articles view:

/components/com_content/views/featured/tmpl/default_item.php

If you already overrode this file in template, it will be this place:

/templates/business_pro/html/com_content/featured/

Yes You have right! Thanks.

I solved with the new path
components/com_content/views/featured/tmpl/default_item.php

with override
/templates/business_pro/html/com_content/featured/

Now remain
other two question:
1 - Reduce automatically the number of characters in featured articles

2 - Reduce automatically the image in home in featured articles

If You have suggestion I appreciate.
Meantime I will search around..

Hi paoloci

This is pretty old template developed from old version of Joomla which doesn't separated introtext and fulltext for articles.

In this case, you can go to each article and decide which text you want to show and add the readmore button next to that text.

For the images, you can use custom CSS to force dimension for it:

.blog-featured .item img {
    width: 300px;
    height: 200px !important;
}

Thanks a lot!
You say

This is pretty old template developed from old version of Joomla! which doesn't separated introtext and fulltext for articles.

What I missed?
Could You explain well with an example?

About read more..
Exist a way to know automatically with a selection how many words are in a specific selection?
In this way I can set perfectly a precious number of characters before the read more.
I use editor JCE and ask also at the developer..

Thanks for all.

Basically the structure of an article will be:

Introtext

Readmore button

Fulltext

The readmore button will be the divider between intro and fulltext.

From Joomla 3, on category blog page or featured blog page like your homepage, it will take the intro text of article to show on frontend. It also provides 2 images: intro image and fulltext image respectively.

In old version of Joomla, it doesn't separate intro and fulltext so it displays all text on frontend.

Yes, I understand now.. thanks for all the help and patience.
Have a good day.
