Cropping / Resizing

Hi @hshah!

The option we have is the Focus X and Y points:
https://smartslider3.helpscoutdocs.com/article/1295-slide-settings-background#image-tab

You can use these to select which part of your image should stay in focus. So it is not automatic, but you can set it manually.

If you want a header, that always loads a different image, you would need the Randomize and Maximum slide count options, which his only available in the Pro version of our slider:

I read about the Randomise option, which is why I was asking this question in the first place ??

I basically want to use the dynamic functionality to display images attached to a certain custom post type… this part seems fairly straightforward.

The issue I am foreseeing is that the Focus X and Y options wouldn’t be very useful because the images could vary. If I am having to go pick them out and set the focus percentages, then I might as well not bother with the dynamic functionality and pick the images manually.

/Edit: Can the Focus X and Y percentages be set for all images in a slider, or do you have to go in and define them manually for each image?

Yes, I’m sorry but for this case we don’t have an option. So if you want focus points, the best you can do is setting the images manually.

@nextendweb_gabor

If I could find a way of getting such information to be added to the post meta, could I set the Focus X and Y values based on that?

Hi @hshah

We’ve added a variable field to the Focus X and Focus Y fields. I have uploaded a new build here for you to try: https://www.dropbox.com/s/h1f9y5mywp10ont/nextend-smart-slider3-wordpress.zip?dl=1

You should just go to your Plugins list, delete your current Smart Slider 3 (don’t worry, your sliders will stay) and install the new build like this:

Wow, I wasn’t expecting anything this quickly!

Just testing it out now and was wondering if variables can handle fields stored as arrays? For example, I have this in one of the postmeta fields:

a:2:{s:3:"top";s:5:"77.38";s:4:"left";s:5:"50.70";}

Which is basically:

Array
(
    [top] => 77.38
    [left] => 50.70
)

I probably could alter the plugin I am using to create separate fields or have the values as just a string with a space in between, but thought I would ask this question here first ??

Hi @hshah

No, I’m sorry but the variables can’t work with arrays. You’d need to separate these values as simple number fields to be able to use them.

@nextend_ramona

No worries, it didn’t take me long to write a small function to result in this:

I used the round() function to make the values set into whole numbers when adding the new post meta.

Now just a simple matter of setting those as variables.

I should be able to test properly today and give you some feedback ??

@nextend_ramona

Does the free version allow you to use post_meta variables?

Hi @hshah

Sure, they’re added automatically as variables.

@nextend_ramona

All I see is the default post meta:

id
url
title
content
description
author
author_name
author_url
author_avatar
datemodified
category_name
category_link
featured_image
altimage
thumbnail
url_label
excerpt

I’ve cleared caches etc but none of the other post metas seem to show up.

Hi @hshah

Are you seeing these in the record viewer: https://smartslider3.helpscoutdocs.com/article/88-generator-functionality#settings
or at the Insert variables?

I created a simple meta using the default Custom field option:

and it shows up fine:

Could there be something wrong with the build you uploaded?

When I try and use the Posts by Filter option is get no results.

The Posts by ID works though but the custom metas don’t show up.

I don’t think so. I’m using the same build.

Try running a plugin/theme conflict test: https://smartslider3.helpscoutdocs.com/article/1569-how-to-do-a-plugin-theme-conflict-test
maybe there will be a conflict causing this problem.

“When I try and use the Posts by Filter option is get no results.”
Please make sure that the filters (at step 4: https://smartslider3.helpscoutdocs.com/article/139-wordpress-posts-generator#tutorial ) are set in a way that there should be result.

I completely removed and reinstalled the plugin (deleted tables etc as well).

This is the Posts by Filter screen I see. The only thing I changed was the Slides value from 5 to 50 just as a test… it finds nothing.

Just had a thought… this wouldn’t find attachments would it? Maybe that’s the issue… I’m trying to get images which are of type “attachment” and this is only looking at standard posts.

I don’t see an option anywhere to get attachments (ie media) dynamically.
