Adding image to twig template from variable

Solved by Chris Jung View solution

I am trying to define three filenames to be included in a slider.

Filenames are defined in the page as:

YAML

---
slide1: myimage1.png
slide2: myimage2.png
slide3: myimage3.png
---

And in the Twig template I would like to get something as:

TWIG

<img src="{{ page.media[slide1].url }}" alt="MyPassion" />
<img src="{{ page.media[slide2].url }}" alt="MyPassion" />
<img src="{{ page.media[slide3].url }}" alt="MyPassion" />

But I am not being able to get the src properly filled.
Could someone help me to understand how to use a variable in a <img> inside a Twig template.

slide1: myimage1.png
slide2: myimage2.png
slide3: myimage3.png

slide1 is header.slide1

<img src="{{ page.media[page.header.slide1].url }}" alt="MyPassion" />

thanks, but I get unknown!
Note: myimage1.png, myimage2.png and myimage3.png are in the same folder as the markdown page definition (not in the template folder).

It works for me

9 years ago

@dimitrilongo:
<img src="{{ page.media[page.header.slide1].url }}" alt="MyPassion" /

I tried this in the template (solution.html.twig):
<p>{{ page.header.slide1 }}</p>

And I can't get the content of slide1, I get an empty html paragraph tag.

In the page solution.md I have:

YAML

# more solution.md
---
title: Ventas y CRM
slide1: sales_1.png
slide2: sales_2.png
slide3: sales_3.png
slide1_alt: Sales 1
slide2_alt: Sales 2
slide3_alt: Sales 3
---

This works perfectly fine:

< img src="{{ page.media['sales_1.jpg'].url }}" / >

So the issue seems to be in page.header.slide1.

BTW I am creating a new theme from scratch (I created the basic structuring following official documentation)

Guys, anyone checked the filenames?

TXT

slide1: sales_1.png

Won't work together with the .jpg files.

Please check the filenames 🙂 and use

TXT

slide1: sales_1.jpg

in your header ;-)

Thanks.
