I've been trying to make something visible only on certain entry_id in expressionengine
{if entry_id="33"}
... show certain content
{/if}
is this even possible in eemcs?
thanks
Sure - but you need to use the {entry_id} variable within a tag pair that provides that variable. For example within a {exp:channel:entires} tag pair.
If you're using url_titles in the URI you may want to think about using segment variables instead. For example:
{if segment_2 == "blog-post"} You're on a blog post{if}
This is what's referred to as a simple conditional in EE, and it's fast enough.
One very important thing to remember in EE is that the standard if:else/else:if routine of an advanced conditional can be very slow, primarily because EE renders all of the code segments and then works its if:else magic. If you find yourself testing many ids or groups, this slows the site down proportionally. In fact, sometimes EEs parse order can stop if:else from functioning entirely.
Instead, consider Mark Croxton's Switchee, a fantastic free plugin that lets you have as many conditions, even nested conditions, without slowdown. It parses just the conditions, then when triggered, is smart enough to descend and run the right code segment:

I am using :xpath attribute frequently to identify an element for my automation scripts using Watir and found it really amazing. It is least changing attribute so less work to maintain automated scripts.. off course for those elements which can't be identified otherwise easily through :id, :name, :value attributes..
I am bit concerned to take some expert advise before building so many automated scripts using :xpath.
What is disadvantage of using :xpath to identify an object using Watir?
Do :xpath value of an element will be same in IE, Chrome and FF?when
Is there anything else important i should be aware about using :xpath?
Thanks
The xpath should always be the same in all browsers.
The problem with using xpath is that it is the easiest locator to break, as the locator for the element is dependant on nothing else in that xpath changing. e.g. if you are locating a results table on a page using an xpath and at a later date another table gets added above the table, then the xpath will be broken and your tests will fail until you update the xpath. If that table was located using an id then adding the second table wouldn't break anything as the new table would have a different id.
If the pages you're working on don't have id's and it isn't an option to add some/ ask for some to be added then remember that in watir you can use multiple locators.
e.g. #browser.table(class: 'results_table', text: /Original results table/)
This is a silly example but hopefully it illustrates the point. If there are cases when using multiple locators still won't work for any reason, then I would look into using css selectors instead of xpath as you should be able to achieve the same things but it will be less brittle.
The issue of how often tests break isn't too important in a small test suite, especially if you're the only one working on the tests. However, a couple of years from now when you have hundreds of tests to maintain and two or three people sharing the codebase you can end up spending longer fixing old tests that you spend writing the new ones. It's worth doing anything you reasonably can to minimise this as you go along as doing a rewrite later will always take longer.
Hopefully some of this helps!
I have a loop of entries and I want to apply formatting to every second entry - not just applying a class but also some basic HTML markup. How can I do this?
This question seems to come up a lot so I thought I would post a simple example:
{exp:channel:entries channel="whatever"}
{switch="<div class='entry'>|"}
<h2>{title}</h2>
{if count != total_results}{switch="|</div>"}{/if}
{if count == total_results}</div>{/if}
{/exp:channel:entries}
In this example, a div with a class of "entry" is wrapped around every second entry. The switch variable at the front end is pretty straight forward. The back end uses two conditionals: if the entry is the last entry in the loop, close the DIV. If the entry is NOT the last entry in the loop, close the DIV only for every second entry (a reflection of the switch variable at the beginning of the loop).
Important to note here that the switch variable is very sensitive to quotes - so when inserting HTML in this fashion, inside the switch variable, you have to use single quotes rather than double quotes. This is fine for simple insertions, but may be a bit unfriendly if you have more complex formatting in mind. Hopefully this helps some folks and feel free to expand on this idea.
There is also a plugin which might help in this situation GWcode Alternate. I haven't used it myself as I prefer to use the native switch tag mentioned in the other answer.
The example I had used was specifically for those instances in which a DIV is not desired on EVERY entry but rather a wrapping DIV around certain intervals - common when you want to have a jQuery slider that includes 3 entries at a time, for example. This was expressly the purpose of my example. EVERY entry is not what I would consider intervals, which is what my example was intended for. Certainly it is an edge case - but an edge case that occurs often enough to capture a simple solution to the challenge that still uses native functionality with only simple conditionals.
I'm creating a set of custom templates and structures for a Liferay site.
One structure provides for a repeatable section, which its matching template then iterates over.
However, for styling reasons, I need to know how many instances of the repeatable section are actually present, and I need to know before I loop.
So, the template code is something like this:
#foreach($thisChunk in $chunk.getSiblings())
[emit some HTML]
#end
I want to do some conditional logic before the foreach, and emit a different CSS classname on the containing element depending on how many $chunks there are.
Any ideas how to access the number of siblings without looping through them first?
Easy: $chunk.getSiblings().size()
How to find out? It's a plain old Java object (java.util.ArrayList in my quick test). You can find this out when you just temporarily debug your template with $chunk.getSiblings().getClass().getName() and then continue with the interface of that class.
I'm relatively new to Expression Engine, and as I'm learning it I am seeing some stuff missing that WordPress has had for a while. A big one for me is shortcodes, since I will use these to allow CMS users to place more complex content in place with their other content.
I'm not seeing any real equivalent to this in EE, apart from a forthcoming plugin that's in private beta.
As an initial test I'm attempting to fake shortcodes by using delimited strings (e.g. #foo#) in the content field, then using a regex to pull those out and pass them to a function that can retrieve the content out of EE's database.
This brings me to a second question, which is that in looking at EE's API docs, there doesn't appear to be a simple means of retrieving the channel entries programmatically (thinking of something akin to WP's built-in get_posts function).
So my questions are:
a) Can this be done?
b) If so, is my method of approaching it reasonable? Or is there something stupidly obvious I'm missing in my approach?
To reiterate, my main objective here is to have some means of allowing people managing content to drop a code in place in their content that will be replaced with channel content.
Thanks for any advice or help you can give me.
Here's a simple example of the functionality you're looking for.
1) Start by installing Low Replace.
2) Create two Global Variables called gv_hello and gv_goodbye with the values "Hello" and "Goodbye" respectively.
3) Put this text into the body of an entry:
[say_hello]
Nice to see you.
[say_goodbye]
4) Put this into your template, wrapping the Low Replace tag around your body field.
{exp:low_replace
find="[say_hello]|[say_goodbye]"
replace="{gv_hello}|{gv_goodbye}"
multiple="yes"
}
{body}
{/exp:low_replace}
5) It should output this into your browser:
Hello
Nice to see you.
Goodbye
Obviously, this is a really simple example. You can put full blown HTML into your global variable. For example, we've used that to render a complex, interactive graphic that isn't editable but can be easily dropped into a page by any editor.
Unfortunately, due to parse order issues, EE tags won't work inside Global Variables. If you need EE tags in your short code output, you'll need to use Low Variables addon instead of Global Variables.
Continued from the comment:
Do you have examples of the kind of shortcodes you want to support/include? Because i have doubts if controlling the page-layout from a text-field or wysiwyg-field is the way to go.
If you want editors to be able to adjust layout or show/hide extra parts on the page, giving them access to some extra fields in the channel, is (imo) much more manageable and future-proof. For instance some selectfields, a relationship (or playa) field, or a matrix, to let them choose which parts to include/exclude on a page, or which entry from another channel to pull content from.
As said in the comment: i totally understand if you want to replace some #foo# tags with images or data from another field (see other answers: nsm-transplant, low_replace). But, giving an editor access to shortcodes and picking them out, is like writing a template-engine to generate ee-template code for the ee-template-engine.
Using some custom fields to let editors pick and choose parts to embed is, i think, much more manageable.
That being said, you could make a plugin to parse the shortcodes from a textareas content, and then program a lot, to fetch data from other modules you want to support. For channel entries you could build out of the channel data library by objectiveHTML. https://github.com/objectivehtml/Channel-Data
I hear you, I too miss shortcodes from WP -- though the reason they work so easily there is the ubiquity of the_content(). With the great flexibility of EE comes fewer blanket solutions.
I'd suggest looking at NSM Transplant. It should fit the bill for you.
There is also a plugin called Shortcode, which you can find here at
Devot-ee
A quote from the page:
Shortcode aims to allow for more dynamic use of content by authors and
editors, allowing for injection of reusable bits of content or even
whole pieces of functionality into any field in EE
I need to divide long content to sub-pages.
Rule for dividing: Heading1 (H1)
Cms-system: MODX Evolution
As far as i know, there is nothing in modx to use for this kind of problem.
I probably got to do this manually anyway, but i still would like to know if there is a way to do this in MODX Evo / Revo.
Edit:
I need to do this in MODX; sub-pages got to be actual subpages, and original page becomes to container.
Navigation will be done with wayfinder.
Edit2:
All done.. manually. Question still open, though.
This is not possible out of the box and I don't know of any extra that archieves what you want. You would have to write a plugin that acts everytime you save a resource and split up the content, create/delete sibling resources as needed etc. Sounds like a lot of work for what you want to archieve to me.
I suppose you have a look at the MIGX extra. It provides you with a TV with the possibility to store an indefinite amount of distinct TV content sets. Have a look at the documentation and Mark Hamstra's tutorial (with screenshots) to see how it is done. You should define one MIGX entry to consist of a text field for the <h1> and a rich text field for the content of the "subpage".
Afterwards, you can use form customization to hide the original content field and display your MIGX Tv instead.
I think, this is a much easier way to archieve, what you want, and can't think of any way, where you would benefit from actual subpages.
Edit: Sorry, I just recognized that you were asking about Evolution, not Revolution. My solution would work in Revo, but I don't think there's something like MIGX for Evo. Sorry, my mistake.
not 'out of the box' you will have to run your content through a snippet to parse it into separate divs or something that you can run some javascript on to possibly 'tab' the content.
If you need to show the 'subpages' in your navigation, you will probably have to use the gatResources extra to parse your content ~ which will be very expensive on resource usage.
You can (depending on how you're using the tree) just create actual sub resources under the parent resource, using Ditto or Wayfinder to build navigation for it.
If you can't use the tree like that (though from your description I think you can), you could also set up a number of template variables ("content1", "content2", "content3" etc) and show that with a simple snippet or so.
