Dynamic Slide - Basics

In this article

How do generators work?

Generators dynamically create slides based on the selected sources, like WordPress posts, Joomla articles, WooCommerce products, Facebook pages, etc.

A generator always displays the content you set it to display at the backend. This also means that the content of the generator won't change based on the page you publish it. For example, if you create a slider from the latest 5 posts, then the slider will always show the last 5 posts. If you add a new post that will appear automatically in the slider, without having to add it manually.

Generators are working from cache, which means their content is updated after the cache time expires.

☝️ Note: The WordPress Post and WooCommerce generator update automatically when you update a post or product.

Where can I access the generator settings?

You can access the generator settings either from the slide menu:

or from the slide editor's breadcrumb menu:

Slides

This is how much slides will be created with your generator.

Cache Expiration

The generator works from cache, and this is how often it will query the new data. It works this way, because if the cache expiration time is 24 hours, and let's say you will get 100 visitors a day, who will check 5 of your pages (which show this slider), then our slider will only go through the database and the longer PHP codes once in a day. However, if you set it to 0 to make your data appear immediately, then it will go all 500 times through them. 

If you want the slider to update its content sooner, write a smaller number instead of the default 24. A slider isn't the main content, it's just to advertise them, so you shouldn't care about not having your contents there right when you create them. But if you don't mind sacrificing your pages' speed, then change the Cache expiration time to 0.

You can also manually clear the slider's cache to make it show new data immediately.

Start Index Pro

This number will define from which result should your variables start.

For example, you can use the Start Index feature to create a post slider from your latest 5 posts, where the latest post has different layout than the other 4. For such case, you'll need to create one dynamic slide generator that will display the latest slide (set Slides to 1). Then create another generator, which displays 4 slides (set Slides to 4) starting from the 2nd (set Start Index to 2).

Group Result Pro

You can have multiple result variables on one slide, so you don't need to have for example one post/article on one slide, but you could have two, three or more posts/articles on one slide. Then the next two, three, more posts and articles would get into the next slide, and so on.

For example, you can create Magazine Slider using the Group Result feature.

☝️ Note: If you use the Group result feature, the slides are only generated if every group is full. For example, if you set the group result to 5 (to pull 5 post data into a slide) and you have 12 posts the generator fetches, only two slide will be generated. Slide 1 will contain posts from 1 to 5 and slide 2 will contain posts from 6 to 10. The remaining two posts will only appear if you add 3 more posts.

You can select variables from different result groups at the Insert variable popup, under Select group


The 2nd group is selected, so the second post data will be added.

View Records

You can check what contents are inside your variables. Basically this option is only for knowing more about your generator, but it doesn't change anything inside your slides. So feel free to check this anytime, as it can't mess up anything.

You can check the available variables anytime using View Records

How to work with variables?

Variables provide a way to pull data from the dynamic source (like from a WordPress Post) to your slide. Using variables you can pull the post title, description or URL to your slides.

When you create a new dynamic slide, you'll see a default layout in the Slide Editor. You can remove this layout, or change it anyway you want to.

To work with variables, simply add a layer and find the Data button above the input fields, which appear when you hover over the fields.

Clicking on the Data button will open the Insert variable popup where you can find the list of available variables and the result they'll display.

Variables

This is where you can find all variables pulled by the dynamic slide generator.

💡 Tip: The generator might pull lots of variables. Use the scrollbar to see those that are below the fold.
2
Advanced Generator Functions

This is where you can filter or split the result, or look for images in it. Check the detailed guide to learn more about Advanced Generator Functions.

3
Result

This is where you can see the result the variable will display in the slide. Useful for finding the content you want to display before inserting the variable.

💡 Tip: Empty result? Check the Advanced Generator Functions, maybe they filter out the result. If your variable should contain an image path, make sure the Find image is not enabled!

Insert

You can insert the variable with the selected functions to the layer.

Fallback for variables

You can have fallbacks for your variables, in case they wouldn't contain anything inside them. This is the code you can use:

{fallback(image/1,"http://xy.com/image.jpg")}

so choose the variable you want to give a fallback to, like in this case:

{image/1}

and copy the middle part out, then write it manually into this codesample, and separate the fallback with a comma.

You could have more fallbacks too, just put one inside another:

{fallback(fallback(image/1,thumbnail/1),"http://xy.com/image.jpg")}

This means, that if your {image/1} variable doesn't have any data inside it, the {thumbnail/1} will be used, but if the {thumbnail/1} doesn't have anything either, the http://xy.com/image.jpg will be used in the input you wrote this.

⚠️ Warning: Make sure, that you don't have space characters next to the commas, because it doesn't work like that!

Static Save

Saving the dynamic slides can be handy when you create a dynamic slide on a specific platform and you want to re-use the slider, or just the layout on different sites.

Just click on the Static Save button:

The Static Save will create real slides from your dynamic slides, and the slides won't be connected to the generators anymore. For instance, if you are using a dynamic post generator, and you add a new post, it won't show up.

The original generator will not be deleted, but it will be unpublished if you hit Static Save.

Common Questions

1
How to hide a layer if the variable is empty?

When you're at the dynamic slide, go to the layer window's Style tab and use the Hide when variable empty field to select a variable.

When the selected variable is empty, the layer will not show up.

How to randomize dynamic generator slides? Pro

You can't really have a random slider, but you could make your dynamic slide to look like it's random. You should go to your generator settings, and give a big number to the Slides option:

This way your slider would have in this case 100 slides, which aren't random yet. Then go to your slider's settings, to the Slides → Max count option, and give the number of slides you really want, like 10:

Then turn on the Randomize and Randomize first options:

Now since we are working from cache, that is why your slider can't be truly random. So for the cache we have the "variations" option, which means, that this many random sliders will be created, and those will change each other, but the random order, that each slider has will be always the same random order. So you could write a bigger variations number, like 20:

and this way what will happen is, that every time your generator's cache expiration time ends, your generator will ask down datas for 100 slides, then the randomization option will create 20 sliders containing random 100 slides, and the maximum slide count option will only make your slider to show the first 10 slides.

☝️ Note: You might need to turn off the Cache Support option at the Randomize.

Why arent the date options work correctly?

At some event generators there are options to show events based on whether or not they have started/ended yet. Most of these options are using the default WordPress (Settings → General → Timezone) or Joomla (System → Global Configuration → Server → Server time zone) timezone option.

Some of the plugins or extensions of our dynamic slide generators are offering they own time options, so if your framework specific time doesn't solve your issue, you should check out your plugin's/extension's global settings, in case it has a "timezone" or some similar option.

Also, don't forget that the generators are working from cache, which means their content is updated after the cache time expires. So if the generator's cache has not refreshed yet it won't show the new events, even if their date is expired. Try lowering the Cache Expiration to e.g. 1 hour, or manually refresh the slider's cache at the Slider Actions to get the updated result.
