I'm using LiipImagineBundle for an application built with symfony2 and I want to display a default image, when a image does not exists.
Let's say I have
<img src="{{ ('/profiles/foo.JPG') | imagine_filter('bar') }}" />
How could I display default.jpg when '/profiles/foo.JPG' does not exists?
Thanks,
This is an old question but the correct (and probably easiest) way to do this is to specify a default_image in the liip-imagine configuration file.

Ok Martin Lie i have foud a link for you and i hope you will directly undeerstand the scenario because by default Twig can not test if a Phisicall object exists or not.. so you must create a service that will help you to make it directely in Twig...
Create a service for twig
Don't worry !
You test if the variable the image exist...
for example is you have sent your image from a controller
just make:
{% if image is defined %}
<img src="{{ image | imagine_filter('bar') }}" />
{% else %}
<img src="{{ ('/profiles/default.jpg') | imagine_filter('bar') }}" />
{% endif %}

I am trying to src an image into my html. Using Laravel as a backend.
<img class="card-img-top" src="storage/app/public/photos/{{$photo}}" alt="Card image cap">
I have also used the system link command and tried,
<img class="card-img-top" src="storage/{{$photo}}" alt="Card image cap">
In the past this would have been sufficent however, when using Laravel this does not link the image.
Does Laravel not allow direct 'src' links, or am I messing up the 'src' file structure?
Laravel uses blade syntax, variables ($) need to be between {{ }} in order to output their value.
So give <img class="card-img-top" src="storage/app/public/photos/{{ $photo }}" alt="Card image cap"> a try :)
i think the simple call like
<img src="storage/image/{{$data->photo}}" alt="">
$data = result from foreach
photo = column in db.
Correct file path is:
src="storage/photos/{{photo}}"
It skips /app/public
src="{{ url('assets/img') }}/{{ $item->photo }}"
Works for me!
I am trying to make a jekyll blog with github-pages.
In order to get some pictures from a folder, I used this gist: https://gist.github.com/jgatjens/8925165
Now, I want to make it a little bit more flexible so that it would get a front matter variable ( page.folder ) and would return the images from there.
My problem is that whenever I assign a folder variable to the front matter and then pass it to the block like this:
{% loop_directory directory:page.folder iterator:image filter:*.jpg sort:descending %}
<div class="item">
<a class="content" href="{{ site.baseurl }}/{{ image }}" title="portfolio 2015">
<img src="{{ site.baseurl }}/{{ image }}"/>
</a>
</div>
{% endloop_directory %}
In the directory attribute it passes page.folder instead of, for example "images/portfolio" which is defined on the front matter. I am rather new at ruby so I can't find something refered to that problem. Is it a bug or something that I need to write correctly to pass the variable?
Did you tried:
{% loop_directory directory: {{page.folder}} iterator:image filter:*.jpg sort:descending %}
I had figured it using the context object to get the front matter attributes,
but unfortunately github / github-pages do not accept plugins (_plugins folder), so a day was wasted for that.
I resolved to github's solution, to create a _data folder and use a text-based (yaml) format to list all my extra assets in an organized way.
I have a website that consists out of a few 'slides'. Each has a fixed structure, used by some scripts, but variable content. I'm hosting it on github and am now trying to use Jekyll to make it easier to add new slides.
I already have each slide in a different html file, which I include in the main page: {% include_relative _slides/about.html %}. Now I'm trying to make it a markdown file, and I wanted to use front matter to make a layout that each slide's file could use. I can include a markdown file, and get it to render by doing:
{% capture myInclude %}{% include_relative _slides/test.md %}{% endcapture %}
{{ myInclude | markdownify }}
However, when I add a front-matter block to it with a layout defined in it, the layout doesn't get applied. It just gets rendered as a horizontal line (for the first ---) and then "layout: slide title: Test Slide —" in plain text.
Is there any way to fix this? Or perhaps a better way to break up my index.html and the slides in it?
Thanks a lot!
Note: Sorry if this was asked before, I Googled everything I could imagine it would be called.
I found something that works for me. I divided my template in two parts, the part above the content, and the part under it. Then in the file I include, there are two includes as well, one at the top and one at the bottom.
So my 'slide' files look like this:
{% include slide_start.html title="About" image="images/about.jpg" %}
... the content of the slide ...
{% include slide_end.html %}
As you can see, in the first include I give some parameters, these will be filled in and can be accessed with the liquid tags {{ include.something }}.
My slide_start.html looks like:
<div class="slide">
<div class="header">
<span>{{ include.title }}</span><!-- no whitespace
--><img src="{{ include.image }}" alt="{{ include.title }}"/>
</div>
<div class="content" markdown="1">
the slide_end.html is just two closing div tags.
You're trying to mix the page/post and the include strategies.
Page/post have a front matter and are decorated with a template, which can itself be decorated. `mypage.html -> layout: page -> layout: default.
Includes are included in page/post but they are only code parts. They cannot be decorated with a template.
You will have to choose.
Take a lool at https://github.com/shower/jekyller this can be helpfull.
I have an problem with displaying my uploaded image to web/images when using the following line below while inside of the blog text or using a data fixture.
I've tested it by manually calling in the code to display the image inside of the Twig file but I want to use this in a fixture/entering it in the blog text to customize the size/alignment of the images for each post.
Can someone show me what's preventing the image from displaying?
Cheers!
This refuses to display image while in a fixture or inside blog text: (shows an outline of the proper sizing and alignment of image inside the blog text but not the image itself)
<img class="alignleft" src="{{ asset(['images/', news.image]|join) }}" alt="" width="290" height="275" />
Using a web link for an image works fine when in a fixture or when entering a blog text:
<img class="alignleft" src="http://www.example.com/example.jpg" alt="" width="290" height="275" />
Using autoescape false to display the blog text:
{% autoescape false %}
<p>{{ news.blog }}</p>
{% endautoescape %}
You're trying to render a string(variable) as a (sub-)template.
That's why twig isn't processing the {{ asset() }} function.
Auto-escaping is not what you're looking for as it doesn't enable processing of twig functions inside strings.
solution:
the template_from_string function
1.) Enable the Twig_Extension_StringLoader extension that comes bundled with twig in your config.yml
services:
# ...
twig.extension.stringloader:
class: Twig_Extension_StringLoader
tags:
- { name: twig.extension }
Now clear your cache using app/console cache:clear.
2.) If you have your template stored in a variable named news.blog you can now use the function as follows:
{{ include(template_from_string(news.blog)) }}
more information in the documentation: template_from_string
It doesn't necessarily have to be something Jekyll uses.
Basically I'm creating a gallery that will use lightbox. I want to load all the images from a directory (_site\images\gallery) for the lightbox to display and their thumbnails (to be determined and created).
What would be the best way to go about this? I already have lightbox set up and tested (no thumbnails).
Thanks in advance.
Jekyll doesn't have a way to "list the contents of a folder".
You can do a very approximate thing by using the yaml front though.
In the "gallery page", include a section with the file names of the images:
---
images:
- a.jpg
- b.jpg
- c.jpg
<other properties, like title, etc>
---
Then, when you want to list your images, produce the links with a loop. I'm not familiar with lighbox's syntax for images, but it will probably look like similar to this:
<ul class="something">
{% for image in page.images %}
<li class="something">
<a rel="something" class="something" href="/path/to/images/dir/{{ image }}" />
</li>
{% endfor %}
</ul>
(I have put "something" on every place when I'm not sure about something. It might be possible that you will have to remove some "somethings" completely. You will have to modify /path/to/images/dir/ to where your images are)
Once the html is changed to work with lightbox, the only thing you have to do to add a new image is: a) putting it in the images directory and b) Edit the gallery page, and introduce the new image name in the list.
It's not as convenient as having the list "automatically generated", but it's very close.
Listing the jpg files in the current directory in Jekyll can be done like this:
{% for file in site.static_files %}
{% assign pageurl = page.url | replace: 'index.html', '' %}
{% if file.path contains pageurl %}
{% if file.extname == '.jpg' or file.extname == '.jpeg' or file.extname == '.JPG' or file.extname == '.JPEG' %}
<img src="{{ file.path }}" />
{% endif %}
{% endif %}
{% endfor %}
More about this solution can be found here: http://jekyllrb.com/docs/static-files/. I have created a lightbox extension for Jekyll that is listed on my page Jekyll without plugins. Check it out!
Try https://github.com/simoarpe/azores-image-gallery
DISCLAIMER: I'm the author.
I've tried some of the projects already available on Github but most of them are discontinued or partially working and in the end, I decided to implement something on my own starting from the good bits found around.
The result is Azores Image Gallery.
For a more detailed explanation check the README file.
I love Jekyll plugins.
Try one of these: Jekyll Gallery, Jekyll Gallery Generator, or Folder Gallery.
Check out the Ruby file for each plugin and modify the image tag generated to include the class for lightbox. That should do the trick. Don't forget to include the lightbox css file in your default template page.
