Unable to get multiple ids in a SBL field about sections_event HOT 5 CLOSED

To be clear both image entries are created, but only the first id gets passed through to the hidden input.

from sections_event.

Given this HTML

<input name="images[]" value="v1,v2,v3"/>

in PHP you will get an array called images and the element with first index 0 will contain the data:

$_POST['images'][0] === 'v1,v2,v3'

Given this data, SBL field will store only v1. (see this line)

Given you want to link multiple entries, you have to pass them as elements of the array:

$_POST['images'][0] ==== 'v1'
$_POST['images'][1] ==== 'v2'
$_POST['images'][2] ==== 'v3'

So in HTML you will need something like this:

<input name="images[]" value="v1"/>
<input name="images[]" value="v2"/>
<input name="images[]" value="v3"/>

Applied to your example, you will need

<input name="sections[listings][images][]" type="hidden" value="%images[0][system:id]%"/>
<input name="sections[listings][images][]" type="hidden" value="%images[1][system:id]%"/>

=> in PHP

$_POST[listings][images][0] === %images[0][system:id]%
$_POST[listings][images][1] === %images[1][system:id]%

from sections_event.

Sorry, I posted the wrong code. I'm actually using:

<input name="sections[images][0][image]" id="sections_images_0_image" type="file">
<input name="sections[images][1][image]" id="sections_images_1_image" type="file">
<input name="sections[listings][images]" id="sections_listings_images" type="hidden" value="%images[0][system:id]%,%images[1][system:id]%">

I'm not trying to pass an array for multiple listings entries. I am creating one listings entry with many images. Basically it should be the same as the Readme's Example 4 (books and authors):

My SBL has multiple selection enabled, so it should receive the IDs of both image entries, but something is not going through.

Ah ok, I got it. So the behavior of SBL for multiple selections is to pass an array, not a comma separated list.

I got confused by Example 4. Assuming Example 4 is passing the IDs to a SBL and not a text field, then shouldn't it also be passing an array of values?

Yep.

You are right. Thanks. Fixed it in this commit.
