I am using the following function in twig to show a part of the content of the description of a news item saved in a database:
{{ new.description|striptags|truncate(300,true)|raw|nl2br }}
With this function inside a p
element in the html, I get the text whose characters do not exceed 300 and then I add "Read More" with an element a
:
<p >{{ new.description|striptags|truncate(200,true)|raw|nl2br }}
<a class="href_blue" href="{{ path('new', {'id': new.id}) }}">
<strong> [Read More] </strong></a>
</p>
This code works for text that comes in a paragraph with more than 300 characters, but if for example I have another one with several "p" elements that are then changed in twig to
elements and I need it to only show me several lines because I have A maximum elevation of the container where it is displayed, I would not know how to do it, since it shows me all line breaks until it does not exceed 300 characters.
To clarify it a little more, I show an image of the result:
What I need is that in the case of Title2 having many line breaks, just show some and add the "Read More" before so that the height of the div is equal to the previous one (to show the example I removed the max- Height and overflow: hidden).
How could I get that?
I greet your help in advance.
You could do something like this in Twig:
Now you can use the
summary
variable in your twig file to show the truncated summary.EDIT #2 based on comments
Then try this instead:
