I'm using pelican to create a website. I'm trying to add an image to the summary so that the summary always starts with an image.
I tried adding the image to the summary in the metadata (using markdown) but it only shows up on the index page and not on the other pages (in the example below the image does not show in the Posts page). I also have to add the image in the same line as the text which sometimes renders in a weird way (some text is to the side of the image depending on the image size).
Here is an example of the metadata:
Title: this is my title
Slug: slug
Date: 2017-05-04 23:00
Category: Posts
Tags: pelican
Author: Eyal
Summary:  and this is my post summary
I also tried to use the summary plugin but that but that did not work at all.
What is the easiest way to add an image to the summary? I was hoping to avoid modifying the html code if possible.
Add the image as a field metadata in your article, say it "Cover", like this:
Title: this is my title
Slug: slug
Date: 2017-05-04 23:00
Category: Posts
Tags: pelican
Author: Eyal
Cover: images/fig1.png
Summary: and this is my post summary
So you can use it in your template in this way.
{% if article.cover %}<img src="{{ article.cover }}" alt="">{% endif %} {{ article.summary }}
This line looks for Cover key in the metadata, and if there is one, create the img tag. If is not, then simply pass.
Ad it there where article.summary already is used. I use pelican-theme alchemy (that uses bootstrap) and article.summary is in index.html. I extended it as follows:
<div class="col-sm-8">
<h4 class="title">{{ article.title }}</h4>
<div class="content">
{{ article.summary|striptags }}
{% if article.cover %}
<div class="container"><div class="col-md-6" style="padding-left: 0px; padding-right: 0px;">
<img src="{{ article.cover }}" class="img-fluid">
</div></div>
{% endif %}
</div>
</div>
This works for me with the pictures in the images-folder.
But I have an other problem: the posts do not find the pictures in the same images-folder :-(
For those using the AboutWilson template in Pelican I have managed to make it work as well by adding the following code in the index.html file (in the template folder)
{% if article.cover %}
Cover:
<span>
<img src="{{ article.cover }}" alt="">
</span>
{% endif %}

I'm building a component which checks the character count of a custom product metafield; if it's above 24 characters, the data is output as an accordion, otherwise the metafield content is printed in its entirety. The conditional below fails as the metafield size always returns 0, but I can see the content printing via the else statement so I'm certain the path is valid:
{% if product.metafields.custom.product_note.size >= 24 %}
<div class="product-note has--dropdown">
<span class="item__heading item__trigger">Product information</span>
<div class="item__content">
{{ product.metafields.custom.product_note }}
</div>
</div>
{% else %}
<div class="product-note">
<div class="item__content">
{{ product.metafields.custom.product_note }}
</div>
</div>
{% endif %}
I'm not sure it's relevant, but the product_note metafield is a multi-line text field. If anyone could point me in the right direction as to why size is failing to produce a value, I'd appreciate it massively.
You could always try working off the value contained in the metafield. It appears you are short-cutting by referring to just the combo of namespace and key, without actually saying: what is the length of the value stored at that namespace and key. Just a thought. You could at least try that.
Final answer, courtesy of #David Lazar's suggestion:
{% assign data_product_note = product.metafields.custom.product_note.value %}
{% if data_product_note.size >= 24 %}
<div class="product-note has--dropdown">
<span class="item__heading item__trigger">Product information</span>
<div class="item__content">
{{ data_product_note }}
</div>
</div>
{% else %}
<div class="product-note">
<div class="item__content">
{{ data_product_note }}
</div>
</div>
{% endif %}
On a Shopify product page, I can loop through all the variants and get information about them like this:
{% for variants in product.variants %}
{{ variants.id }}<br>
{{ variants.sku }}<br>
{{ variants.title}}<br>
{{ variants.price | divided_by: 100}}<br>
{% endfor %}
This works perfectly fine, however when I try and get the variant image in the loop like this:
{{ variants.image}}
I have also tried using:
{{ variants.featured_image.src}}
Which produces exactly the same result.
The output is simpy products and then the name of the image file. For example 'products/my-image.jpg'.
This is obviously not the path to the image and when I try and display this within an image tag, a broken image is produced.
I am trying to get the path to the image that is stored on Shopify's CDN for this variant product, which will look something like https://cdn.shopify.com/s/files/1/0022/4572/2212/products/WI1M1L1F1B1_grande.jpg?v=1656698226.
Does anyone know how this can be achieved within the loop I am using above?
You are looking for this
{{ variant.image.src | product_img_url: '200x' }}
I suggest you to take a look here to find many other useful functions: https://www.shopify.ca/partners/shopify-cheat-sheet
Also is useful to download a free theme (Dawn for example) and use it as reference.
Here is a code example to show each variant image and url :
<div class="product_thumbnails">
{% for variant in product.variants %}
<a href="{{ variant.url }}">
<div class="h-[50px] w-[50px] bg-[#E6ECEB] rounded shrink-0 p-1">
{{ variant.image | image_url: width: 50 | image_tag }}
</div>
</a>
{% endfor %}
</div>
What I want to do:
Capture two variables {{section.settings.{{title}}_modal_title}}
Context:
The links in the linklist are not really used as links, but purely so user can reorganize it in their Shopify portal.
External javascript file creates elements (modals) on click event, value from section.settings.XXX_modal_title is supposed to be used in the created modals.
The linklist:
<ul class="menu">
{% for link in linklists.main-menu.links %}
<li data-menu="{{ link.title | upcase }}" class="menu-link">
<p class="menu-title">[{{ link.title | upcase }}]</p> <-- Click event
</li>
{% endfor %}
</ul>
What I tried:
My first try was adding the liquid tag itself with .insertAdjacentHTML('afterbegin', {{section.settings.${attLowerCase}_modal_title}}) when the element is created, but soon realized that liquid renders the values first. The output of doing this is literally "{{ }}"
My second try was to capture two variables and put it in a hidden input.
{% assign title = link.title | downcase %}
{% capture section_title_variable %}
{{section.settings.{{title}}_modal_settings}}
{% endcapture %}
<hr class="item-line">
<p class="ueq-menu-title">[{{ link.title | upcase }}]</p>
<input type="hidden" id="about_modal_title" value="{{section_title_variable}}">
In depth example:
section.settings
{
"type": "text",
"id": "about_modal_title",
"label": "About window title",
"default": "ABOUT"
},
User clicks on link ABOUT
<ul class="menu">
{% for link in linklists.ueq-menu.links %}
<li data-menu="{{ link.title | upcase }}" class="menu-link"> <-- "ABOUT"
{% assign title = link.title | downcase %} <-- downcase to "about"
{% capture section_title_variable %}
{{section.settings.{{title}}_modal_title}}
{% endcapture %}
<hr class="item-line">
<p class="menu-title">[{{ link.title | upcase }}]</p>
<input type="hidden" id="about_modal_title" value="{{section_title_variable}}"> <-- captured should look like this {{section.settings.about_modal_title}}
</li>
{% endfor %}
</ul>
on click event, get the value from hidden input, and use it when creating elements.
"Why not use {% javascript %}?"
I prefer to do it this way, since most of my script files are external. I like to keep it that way.
"Why capture it like that?"
The links in the linklist are already known, this was in the design. Thats why in sechema one of them is called "about_modal_title". Since this is used inside a for loop, this was the only way I could come up with to connect the title and schema settings with each other.
If someone knows a better way to do this instead of putting it in a hidden input, please let me know :)
In proper Liquid syntax, curly-brackets are never embedded inside curly-brackets
The syntax {{ something_{{ you }}_want }} is illegal Liquid syntax - once an expression is started, using either {{ or {%, everything up to the next }} or %} is evaluated as one template command.
In your example, you're looking to combine two strings in order to get the name of a setting that you want to access. In a dedicated programming language, we would expect there to be nice shortcuts for something like this. Liquid, however, is first and foremost a templating language, and doesn't have such shortcuts. Instead, we will need to accomplish our goal in two steps.
The first thing we need to know is that we can access properties in two ways: {{ settings.fieldname }} is equivalent to {{ settings['fieldname'] }}
Thanks to that second syntax, we can access an arbitrary setting using a variable:
{% assign field = 'fieldname' %}
{{ settings[fieldname] }}
So to do something more complicated, we just need to use assign (or capture - just be aware that capture includes whitespace as well!) to get a variable that contains the name of the field we want to access, then pass that in to the square brackets:
{% assign title_field = link.title | downcase | append: '_modal_title' %}
{{ section.settings[title_field] }}
i'm pretty new to Shopify and I'm facing a strange issue in linklists.
Yesterday I changed the featured image for a category I displayed into a linklist, but I cannot see the changes in the page that prints the linklist.
I analyze the .liquid file that prints the linklists and I found the snippet that produces the divs:
{% for link in linklists[linklist].links cols: 4 %}
<div class="products item {{ link.handle }}">
<a href="{{ link.url }}" title="Browse our {{ link.object.title | escape }} collection.">
<img src="{{ link.object.image.src | collection_img_url: 'large' }}" alt="{{ link.object.title | escape }}" />
<big>{{ link.title }}</big>
</a>
</div>
{% endfor %}
After some shots I tried to add a data attribute to the image to print again the link.object.title:
{% for link in linklists[linklist].links cols: 4 %}
<div class="products item {{ link.handle }}">
<a href="{{ link.url }}" title="Browse our {{ link.object.title | escape }} collection.">
<img src="{{ link.object.image.src | collection_img_url: 'large' }}" alt="{{ link.object.title | escape }}" data-test="{{ link.object.image.src | collection_img_url: 'large' }}" />
<big>{{ link.title }}</big>
</a>
</div>
{% endfor %}
The strange fact is that it prints two different values for the same object!
<img src="https://cdn.shopify.com/s/files/1/0407/7545/files/trousers-woman_c4633f02-59f7-4a4b-809b-91662635ddc0.jpg?22734" alt="Women's Trousers" data-test="//cdn.shopify.com/s/files/1/0407/7545/collections/DSC_9685_grande_df826b7f-5645-4491-b866-8819c9ad8983_large.jpg?v=1429273629">
The src attribute shows the old image, and the test attribute shows the new one.
Is that because Shopify postprocess the src attributes of the image for caching them into their cdn? How can I fix this?
thanks to #Jason input I found a javascript script that changed the attribute "src" of the image:
$('.collection-woman .webshop .trousers a img').attr('src','https://cdn.shopify.com/s/files/1/0407/7545/collections/DSC_9685_grande_df826b7f-5645-4491-b866-8819c9ad8983_large.jpg?v=1429273629');
I’m trying to add a link to a size guide image by having it pull the last image from a collection.
but right now it’s pulling all the images, not the last. how do i just pull the last?
<!-- SIZE GUIDE -->
<div id=“size_guide”>
{% for image in product.images %}
<a href=“{{ image.src | product_img_url: ‘master’ }}” class=“fancybox-media {% cycle ‘,last’ %}”>
SIZE GUIDE</a> {% endfor %}
</div>
</div>
Try using the last array filter. E.g:
SIZE GUIDE
