Sorry for the length, my problem is very simple, but specific.
I'm building a wordpress site that automatically imports image galleries from a Tumblr account, then styles and displays them. The backend is finished, and all that I need now is have all images in posts be displayed as thumbnail sized links. They are not behaving well with the importer (I've tried 6), so I have to edit the HTML display (rather than the images as they are uploaded).
I have decided to do this by applying class="attachment-thumbnail size-thumbnail" on all images on the site (in HTML). I have tested this and they will open the proper gallery in a lightbox as necessary so long as they belong to those two classes.
I have a two part problem.
I do not know PHP past basic syntax, and while I can intuit most of what is happening I don't trust myself to edit Wordpress source code without understanding exactly what I am breaking.
From other answers I've learned that I should most likely edit the wp_insert_attachment() function in post.php under wp_includes/. I have found the function, but don't really know where to go from there, as it does not appear to be specific to image attachments. I don't want to throw any errors by assinging image classes to non-image attachments. How do I add those two classes (attachment-thumbnail and size-thumbnail) to all post images (and only images)?
There is a single exception to this rule. I want a large image on the homepage, and have it not be a link.
It seems like the way to handle this would be to allow page attachments to be handled normally, while attachments that are both images and attached to posts should trigger this:
if [attachment is an image AND is on a post, not a page]:
<img src="https://whatever">
becomes
<img src="https://whatever" class="attachment-thumbnail size-thumbnail">
tl; dnr: ^^ that's all I need to happen, in PHP, in the right file, in Wordpress ^^
Thanks!
So likely you will want to do it via php but instead you could do it with javascript ie jQuery:
<script>
$(function() {
$("body img").addClass("attachment-thumbnail size-thumbnail");
});
</script>
Put that on any page or site header and it will add the class to all images. You can modify the search filter to suit.
You might need to re-call your lightbox initialization code too, or put this before it gets called initially.

I'm trying to insert an inline SVG of a US map in a Wordpress post. A test page where it's been inserted into the post as an HTML block with some light CSS is here: http://thepostrider.com/test-post/
When I edit it in the Gutenberg editor I can see the SVG and all, but on preview/publish nothing. It's clearly there in the code if you inspect the element on that published page but cannot for the life of me get it to manifest in the post. Historically I've gotten around this by building out custom pages and inserting SVGs into php files, but I do need to start building out this kind of thing in individual posts now too; so I would love some advice.
Take a closer look at the HTML source:

It looks to me like Wordpress has converted all your quotation marks into smart quotes (” and ″). That's not going to help.
You would be better off uploading the SVG file as an image and inserting it that way. (You may need to install additional plugins to do this, as Wordpress won't allow SVG uploads in its default state.)
By the way, the next time you ask a question about code or markup, please create a minimal reproducible example and insert it directly into your question. Links to code on other sites are liable to break, making your question useless for others. Thanks.
I've been breaking my head over this for a few days but I yet have to find a proper solution. I'm working on a Wordpress site, where all images inside posts are linking to the corresponding attachment pages. I want to use a lightbox but obviously this would require changing all the links back to the media files directly (e.g. xyz.jpg).
The site has a significant number of posts and images so it would be impossible to do this manually.
Does anyone know of a plugin or other solution that would simply replace - in bulk - all of the image links to link to the media file, instead of the attachment page?
Here is one answer that, although jQuery-based, did the trick, and is much quicker than and safer than a PHP-script to go through the whole DB. The drawback is that it will link to the resized image url instead of the full image url. There's probably a way to catch that with jQuery as well, but this was enough for my needs.
$("article.my-post-class a img").each( function(){
var src = $(this).attr("src");
$(this).parent("a").attr("href", src);
});
I've recently started getting familiar with Atlassian Confluence (v. 3.3), but I'm having trouble understanding the best way to use page hierarchies within a space.
Within a space, pages can be located underneath the "Home" page, or one level higher, next to the home page. However, in the "Documentation" theme, the left sidebar page hierarchy is only shown for pages rooted below "Home". This means that the "Home" breadcrumb is always displayed when viewing pages that appear in the sidebar hierarchy.
So, what is the purpose of having pages on this top level? Should it be used specifically to hide pages from the sidebar hierarchy (like meta)?
Is it possible to have the sidebar hierarchy display for pages rooted next to Home (on this top level), instead of below it?
Is it possible to remove the Home breadcrumb?
How many of these questions are made irrelevant by later updates to the software?
The only real purpose I can think of for having a page on the same level as the home page would be to disclude it from a page-tree display starting at the home page. So if you have some pages you use for holding images, documents, testing content, et cetera then you would not want it to show up in the hierarchy viewed by regular users.
When you define a page-tree macro, or the children-display or anything similar, you can specify which page it is displaying the hierarchy from. If you want to use a page other than the home page, just specify it in the page-tree macro.
I don't believe it is possible to remove the breadcrumb, or at least I don't know how.
Software updates will maybe bring some other page-tree-esque options but won't fundamentally change anything else we're talking about here.
So, what is the purpose of having pages on this top level?
Specifically? You'd have to ask Atlassian.
Generally? The default configuration is that only pages from the specified Home page down are shown in the navbar.
Should it be used specifically to hide pages from the sidebar hierarchy (like meta)?
Yes. Any page which is used for navigation, control or configuration is stored at the top of the hierarchy. That way they don't show up in the navbar.
Using the {alias} macro will create a page in the top hierarchy.
If you use a page as input to your navbar then this page can be stored here out of user sight but still publically visible. So, if you had a page with lots of markup for a colourful and exciting navbar named SpaceNavigation then in the Documentation Theme Configuration you would have this code:
{include:SpaceNavigation|nopanel=true}
Is it possible to have the sidebar hierarchy display for pages rooted next to Home (on this top level), instead of below it?
Yes. Use the pagetree macro.
{pagetree:root=#none}
You can edit the space theme to show anything in the left navigation bar.
Browse > Space Admin > Theme > Configure theme
Untick the 'Page Tree' option at the top. Put your code to display content in the navbar in the navigation box.
If you want a pagetree somewhere in your custom navigation use the {pagetree} macro. You can set the root page to a page lower in the hierarchy. {pagetree:root=apple}
The {children} macro is also useful here.
The reporting macros can print a list of all pages in a space. You can build your own macro or import a wiki page to display as the navbar.
Is it possible to remove the Home breadcrumb?
This may need clarification. Are you looking to remove the breadcumbs or just the word 'home'.
Either way, the answer is 'JavaScript or CSS'.
If you are a space administrator you can add CSS styles to the space to disable CSS for the space from the header.
If you have the {html} macro or {style} then you can add styles and JavaScript to the wiki page.
If you are a wiki administrator, or have one on your side, then you can create a macro or plugin to put CSS or JavaScript code on the page.
Here is a code sample to find two classes on a page and after the page has loaded (document.ready) hide them.
{html}
<script type="text/javascript">
AJS.$(document).ready(function() {
AJS.$(".first").hide();
AJS.$(".second").hide();
});
</script>
{html}
This example will remove the word 'Dashboard' as it has the class of 'first'.
Go forth and write the code to find the objects that so draw your ire and vanquish them.
CSS is also an option and sometimes less messy.
Some CSS objects can be removed from the page from within the page. E.g:
{html}
<style type="text/css">
ol.breadcrumbs { visibility:none; !important; }
</style>
{html}
However, to remove objects at the top of the page you need to use javascript or put CSS in the space style sheet.
Browse > Space Admin > Stylesheet
How many of these questions are made irrelevant by later updates to the software?
It's pretty much the same. Some styles have changed. Some things have been moved around. The general look has changed.
Some of the style sheets have changed and they have said that they are looking to deprecate the Documentation Theme. However, given the community support for the Documentation Theme even if they remove it no doubt it will be available as a downloadable theme in V6.
If you are interested in looking at this yourself then you can download Confluence V5 with a trial licence or try their OnDemand free for one month.
I am having a big time issue with solving a problem. I have a placeholder called main for the content region of the page. I was building that region in the cms. Everything was going great until I attempted to add an embedded video contained in an iframe. When I save django cms completely removed the iframe and left an empty div. So I attempted to use prettyphoto light box to open the video by clicking on an image. The code I added to the page through the cms is:
<a rel='prettyPhoto[youtube]' href="https://www.youtube.com/embed/mqVZF_yb8C0?autoplay=1&start=1765&iframe=true" data-rel="prettyPhoto">Click Image</a>
When I saved, django cms completely removed the data-rel attribute from the link which is obviously needed for the js. So I went a step further and adapted the code of the data attribute to:
rel="prettyPhoto"
and the cms also removed that attribute! Also anytime I add an html5 tag like article of section it hates that too! What gives here? Am I doing something wrong? Any advice would be appreciated.
Aaron,
Thanks.
Please see the discussion at https://github.com/divio/django-cms/issues/1529. We use html5lib to clean the contents of the text plugin (this cannot be turned off for security reasons).
What you'll want to do is write a custom plugin (possibly one that can be embedded inside text plugins).
On the catalog/category page I would like images change when hover. Like clubmonaco.com I know how to do it on html/css but no idea on magento. Any help?
You could modify files in this directory:
app/design/frontend/base/default/template/catalog/product
for example (list/ and list.phtml)
or your template for example:
app/design/frontend/default/yourtemplate/template/directory with product files
CSS files you can find in:
skin/frontend/
You should also think, where the second image is stored. You can use "CSS-Sprites" for this case - a single image file, that contains both photos. The disadvantage is, that you have to customize every page, where magento shows product images.
Alternatively you have to define exact orders. First image is the front view, second image is always the back view.
The programming part is not really difficult. Look at
app/design/frontend/base/default/template/catalog/product/list.phtml
for the Catalog view. Path can vary, if you have a custom template. In the Magento backend there is a feature to show up the real path (system->configuration->development tools).
You can write your Javascript directly into the list.phtml. Magento also writes JS-code directly in the .phtml files. Of course it's not very pretty, but Magento is so complex; if other people work with the shop system, it will be easier to find.
Keep in mind, that the list.phtml contains two layouts: Grid and List View. Just if you do a change and wonder, why you can't see a change in the frontend ;-)
