I am attempting to edit blog.liquid so that on a particular blogs listing, there is a customize graphic above it.
Something similar to this:
<div id="page-header">
<h2 id="page-title">{{ blog.title }}</h2>
</div>
{% if blog.new-years-revolution %}
<p class="alignCenter">**[custom code here]**
</p>
{% endif %}
{% for article in blog.articles %}
<h3 class="blog">
{{ article.title | escape }}</h3>
{% if article.excerpt.size > 0 %}
{{ article.excerpt }}
{% else %}
<p>{{ article.content | strip_html | truncate: 800 }}</p>
{% endif %}
{% endfor %}
Essentially I don't want it to show up on any other blogs, just this particular one. So a basic if statement that says "if on this blog, show this". I'm not sure whether to use the blog.id or blog.handle, and depending on which one, how to reference that particular handle so that this image only shows up on that one.
Hopefully I'm explaining clearly enough. Been googling for a while and haven't found anything helpful yet.
That should be:
{% if blog.handle == 'new-years-revolution' %}
<p class="alignCenter">**[custom code here]**</p>
{% endif %}

I think I'm not even sure what I should be searching for. On my Jekyll Blog I currently have just blog posts that have been written and listed with their full content on the main page and using pagination. I want to follow more Indie Web standards and follow a PESOS (Publish Elsewhere, Syndicate (to your) Own Site) method. I've figured out a way to get data from my Twitter (e.g. post_date, embed code, etc) into a YAML data file automatically. What I want to do is take the data from my posts and combine the data from Twitter and include those posts as if they were also blog posts (the plan is to do the same with Instagram as well).
I've tried a lot of things, but I'm not even sure what is the best way to go about doing this. I'm assuming that it will use something similar to Using Jekyll, how do you alter an array's contents using a for loop?, but I can't seem to make it work. My code for the blog posts is as follows currently:
{% for post in paginator.posts %}
{% if post.header.teaser %}
{% capture teaser %}{{ post.header.teaser }}{% endcapture %}
{% else %}
{% assign teaser = site.teaser %}
{% endif %}
{% if post.id %}
{% assign title = post.title | markdownify | remove: "<p>" | remove: "</p>" %}
{% else %}
{% assign title = post.title %}
{% endif %}
<div class="list__item">
<article class="archive__item" itemscope itemtype="https://schema.org/CreativeWork">
<h1 class="archive__item-title" itemprop="headline">
{% if post.link %}
{{ title }} <i class="fas fa-link" aria-hidden="true" title="permalink"></i><span class="sr-only">Permalink</span>
{% else %}
{{ title }}
{% endif %}
</h1>
<p>Posted on {{ post.date | date: "%A %B %-d, %Y" }} by Jacob Campbell.</p>
{{ post.content }}
</article>
</div>
{% endfor %}
{% include paginator.html %}
Maybe, if your posts and tweets do have the same structure in terms of fields you could concat the two:
{% comment %} Given that you make the tweets accessible from site, as a collection, for example {% endcomment %}
{% assign posts = paginator.posts | concat: site.tweets | sort: "date" %}
{% for post in posts %}
<h2>{{ post.title }}</h2>
<div>{{ post.content }}</div>
{% endfor %}
Mind that, here I am also resorting the list after the concat, via the sort filter, so the tweets do appear in the normal time series of the posts.
And if your structures are not the same, you can always resort to the collection in which your post is:
{% assign posts = paginator.posts | concat: site.tweets | concat: site.instagram | sort: "date" %}
{% for post in posts %}
{% if post.collection == 'posts' %}
<h2>{{ post.title }}</h2>
<div>{{ post.content }}</div>
{% elsif post.collection == 'tweets' %}
{% comment %} If I am not mistaken, twitter have no title concept {% endcomment %}
<h2>There was a bird singing about:</h2>
<div>{{ post.content }}</div>
{% elsif post.collection == 'instagram' %}
{% comment %} So, now, it can fit any social media of your choice {% endcomment %}
{% endif %}
{% endfor %}
I'm looking to display information from a csv file on a jekyll-generated site. I need to search for the appropriate category in the csv file, then display four of them on the page. Filtering to the selected category is no problem, but I'm having difficulty limiting the output to four.
Is there a way to apply a limit to an if statement? Or is there any other way to write this? I'm not that savvy in Liquid, so it's extremely likely that I'm missing an obvious solution.
Basic code to make all the applicable data show up on the screen:
{% for study in site.data.studies %}
{% if study.category contains "foo" %}
<div class="col-sm-3">
<h3>{{ study.title }}</h3>
<div class="list-of-attributes">
<h6>Attributes: </h6>
{{ study.attributes }}
</div>
</div>
{% else %}
{% continue %}
{% endif %}
{% endfor %}
I've also tried unless and tablerow, neither of which worked at all. Am I at least on the right track? How can I limit this forloop to stop at four items?
Thank you!
Ideally data should be filtered before rendering however you can also create a variable in liquid to hold the number of stuff rendered
{% assign rendered = 0 %}
{% for study in site.data.studies %}
{% if study.category contains "foo" %}
<div class="col-sm-3">
<h3>{{ study.title }}</h3>
<div class="list-of-attributes">
<h6>attributes: </h6>
{{ study.attributes }}
</div>
</div>
{% assign rendered = rendered | plus: 1 %}
{% if rendered == 4 %}
{% break %}
{% endif %}
{% endif %}
{% endfor %}
The ideal solution as I said would be to create your own filter which does all the work (filter by category and limit the number of results)
{% assign filtered = site.data.studies | my_custom_filter %}
{% for study in filtered %}
<div class="col-sm-3">
<h3>{{ study.title }}</h3>
<div class="list-of-attributes">
<h6>attributes: </h6>
{{ study.attributes }}
</div>
</div>
{% endfor %}
Presuming that your category is a string, not an array, you can do :
{% assign selected = site.data.studies | where: 'category','foo' %}
{% for study in selected limit:4 %}
<div class="col-sm-3">
<h3>{{ study.title }}</h3>
<div class="list-of-attributes">
<h6>Attributes: </h6>
{{ study.attributes }}
</div>
</div>
{% endfor %}
And if your category is a string like "foo, bar, baz" or and array of strings you can use the jekyll 3.2 where_exp filter like this :
{% assign selected = site.data.studies | where_exp:"item", "item.category contains 'foo'" %}
Is there a way to get ahold of a posts markdown in an include file?
My include file has this code: {{workingPost.content}}
When I include this in a markdown file I get the HTML. I pass that to another include that expects markdown and instead this is passing HTML.
Is there a way to access the markdown instead of the HTML for the post?
As requested here are the code files. What they do is get a featured post for the right hand side of the site like this. In that link the code is static HTML. I want to update it to make it dynamic via the following code. I already have the first image grabbing code working when it receives markdown. I'd like to use that code to grab the first image from the post here too, but by the time the code gets it the markdown has been turned into HTML.
Include file timely.html
{% assign workingPost = nil %}
{% for page in site.posts %}
{% if page.title == 'We Convert All Dollars To Bitcoin' %}
{% assign workingPost = page %}
{% endif %}
{% endfor %}
<div class="panel panel-default">
<div class="panel-heading text-center">
<h3 class="panel-title">Popular</h3>
</div>
<div class="panel-body">
<a href="{{workingPost.url}}">
{% assign workingPostContent = workingPost.content %}
{% include first-post-image-src2.html param=workingPostContent %}
<img src="{% include first-post-image-src2.html param=workingPostContent %}" alt="{{workingPost.title}}">
<p>{{workingPost.excerpt}}</p>
<p class="btn btn-md btn-success" role="button">READ POST</p>
<br>
<br>
</a>
</div>
</div>
include file first-post-image-src2.html
{% capture result %}
{% assign htmlAgain= 'empty' %}
{% assign foundImageAgain = 0 %}
{% assign imagesAgain = include.param | split:"![" %}
{% for imageAgain in imagesAgain %}
{% if imageAgain contains '](' %}
{% if foundImageAgain == 0 %}
{% assign htmlAgain = imageAgain | split:"](" %}
{% assign htmlAgain = htmlAgain[1] %}
{% assign htmlAgain = htmlAgain | split:")" | first %}
{% assign foundImageAgain = 1 %}
{% endif %}
{% endif %}
{% endfor %}
{%endcapture%}{{site.url}}{{htmlAgain|strip}}
Yes translating from markdown to html is one of the first thinks made when Jekyll build. So, no way to grab the markdown in an include. The only way to bypass this limitation is to do it with a plugin. But it's not the subject.
Now back to you code. It's to complicated and fragile.
Jekyll has all the needed functionalities to do what you want to do. Don't try to do data processing with liquid. Use the tags and filters and you will not have to fear a Gem upgrade that will break your site and bring you to a really difficult debugging.
eg : somewhere in your code, you're processing a string with a | split:"/>" filter that rely on how kramdown is rendering ìmg tag. If one day they decide to remove this useless closing slash, your code will break.
The way you can go : put all the datas in your post, in the simplest form possible, and then use them with simple Jekyll tags and filter.
The idea is to use yaml Front Matter custom variables and Jekyll post or page excerpt functionalities.
In your _config.yml, define a new excerpt separator :
excerpt_separator: "<!-- excerpt end -->" # default is "\n\n" = two new lines
In all your posts :
---
excerpt_image_src: "/images/dollarsToBitcoins.jpg"
excerpt_image_alt: "Bitcoin Bulls converts dollars to bitcoins."
popular : true # I'll explain that latter
---
Bitcoin Bulls customers pay in USD but those dollars are all converted to bitcoin.
<!-- excerpt end -->
Bulls, I'm excited to announce...
In default.html
{% if page.is_post %}
<link rel="alternate" type="application/atom+xml" title="{{ site.name }} — Atom" href="{{ site.url }}/blog/feed.atom" />
<meta property="og:image" content="{{ site.url }}{{ page.excerpt_image_src | strip_newlines }}" />
<meta property="og:description" content="{{page.excerpt}}" />
{% else %}
In _includes/timely.html :
<div class="panel panel-default">
<div class="panel-heading text-center">
<h3 class="panel-title">Popular</h3>
</div>
{% for p in site.posts %}{% if p.popular == true %}
<div class="panel-body">
<a href="{{p.url}}">
<img src="{{p.excerpt_image_src}}" alt="{{excerpt_image_alt}}">
<p>{{p.excerpt}}</p>
<p class="btn btn-md btn-success" role="button">READ POST</p><br><br>
</a>
</div>
{% endif %}{% endfor %}
</div>
Note the {% if p.popular == true %} that filter posts with a front matter variable popular: true.
In _includes/blog-post.html :
<li>
<a href="{{ post.url }}">
<p>{{post.date | date: "%B %d, %Y" }}</p>
<img src="{{post.excerpt_image_src}}" alt="{{post.excerpt_image_alt}}">
<!-- No need to wrap excerpt in <p> tag, Jekyll does it.
If you want to put your own tag :
<div>{{ post.excerpt | strip_html }}</div> -->
{{ post.excerpt }}
<p class="btn btn-md btn-success" role="button">READ POST</p><br><br>
</a>
</li>
In _layouts/post.html :
<h1>{{page.title}}</h1>
<div style="color:#666;">by David Smith on {{page.date | date: "%B %d, %Y" }}</div>
{% if page.excerpt_image_src %}
<p><img src="{{page.excerpt_image_src}}" alt="{{page.excerpt_image_alt}}"></p>
{% endif %}
{{ page.content | remove: page.excerpt | markdownify }}
<br>
As you're not actually displaying post excerpt in post page, it's {{ page.content | remove: page.excerpt | markdownify }}. If you want to display excerpt it's : {{ page.content | markdownify }}
I don't know why but page.content return mardown and not html, so the filter | markdownify to transform markdown to html.
Et voila ! Long live Bitcoinbulls !
The markdown isn't available. It is rendered earlier and not available.
From this answer it sounds like the markdown isn't available.
In my case I made my first-post-image-src2.html include handle the case where it gets markdown or HTML like this:
{% capture result %}
{% assign htmlAgain= 'empty' %}
{% assign foundImageAgain = 0 %}
{% if include.param contains '![' %}
{% assign imagesAgain = include.param | split:"![" %}
{% for imageAgain in imagesAgain %}
{% if imageAgain contains '](' %}
{% if foundImageAgain == 0 %}
{% assign htmlAgain = imageAgain | split:"](" %}
{% assign htmlAgain = htmlAgain[1] %}
{% assign htmlAgain = htmlAgain | split:")" | first %}
{% assign foundImageAgain = 1 %}
{% endif %}
{% endif %}
{% endfor %}
{% endif %}
{% if foundImageAgain ==0 %}
{% assign imagesAgain = include.param | split:"<img" %}
{% for imageAgain in imagesAgain %}
{% if imageAgain contains 'src="' %}
{% if foundImageAgain == 0 %}
{% assign htmlAgain = imageAgain | split:'src="' %}
{% assign htmlAgain = htmlAgain[1] %}
{% assign htmlAgain = htmlAgain | split:'"' | first %}
{% assign foundImageAgain = 1 %}
{% endif %}
{% endif %}
{% endfor %}
{% endif %}
{%endcapture%}{{site.url}}{{htmlAgain|strip}}
I have a FOR statement that outputs all posts of type jobs.
{% for post in site.categories.jobs %}
<article>
<h3>{{ post.title }}</h3>
<p>{{ post.summary }}</p>
</article>
{% endfor %}
But if there are no published posts in jobs I would like to display a "We're not hiring right now" message.
Can you create an IF/ELSE statement to check for posts in a specific category?
Try check it with {% if site.categories.jobs == null %}.
{% if site.categories.jobs == null %}
<p>We're not hiring right now</p>
{% else %}
{% for post in site.categories.jobs %}
<article>
<h3>{{ post.title }}</h3>
<p>{{ post.summary }}</p>
</article>
{% endfor %}
{% endif %}
I'm looping through two products - on the post view page I pull in a secondary post (in the example, a related recipe) which parses just fine on the first product page - on the second product page just {{ post.content }} won't parse. I can hack it with {{ post.content | markdownify }} - but I'd like to know why it's breaking. Here's the relevant code:
{% for post in site.categories.recipe %}
{% if post.products contains page.title and post.featured %}
<div class="row">
<div class="four columns">
<h4>{{ post.title }}</h4>
<ul>
<li>Serves {{ post.serves }}</li>
<li>Prep: {{ post.time }}</li>
<li>Share</li>
</ul>
{{ post.content }}
...
<!-- All tags are closed, the rest just isn't relevant -->
{% endif %}
{% endfor %}
Please find my solution with counter
<pre>
{% assign counter=0 %}
{% for post in site.posts%}
{% if post.category == 'blog' and counter < 2 %}
{% assign counter=counter | plus:1 %}
{{post.content}}
{% endif %}
{% endfor %}
</pre>
The markdownify filter is probably making it work because there might be special characters that aren't encoded in the content you're pulling from. I always forget to make my & into &.
If you're using the default Markdown interpreter Maruku, here's a list of the entities that might be giving you problems and their encoded equivalent. http://maruku.rubyforge.org/entity_test.html and more info on Maruku. http://maruku.rubyforge.org/maruku.html
