The following code allows you to upload multiple images but only one is saved to the option. Can multiple images be saved to the option as an array or would I have to create separate controls?
$wp_customize->add_section("slider",array(
'title'=>"Slider",
'description'=>"Choose the images for the slider",
'priority'=>'36'
));
//images
$wp_customize->add_setting("slider[images]",array(
'default'=>"",
'type'=>"option"
));
$wp_customize->add_control(new WP_Customize_Image_Control($wp_customize,"slider[images]",array(
'label'=>__("Images","adaptive-framework"),
'section'=>"slider",
'settings'=>"slider[images]"
)));
You define the setting as an array, however, you over and over reference the same entry
slider[images]
.Note: I did not test this, and I never used WP’s Theme Customization API before. And, of course, you need to take care of deleting images, and handling the remaining images/array entries and the like. This is just a (most probably not working) example.
If you want to store multiple entries in a single setting, use an array (e.g.,
slider_images
). Then, to define one specific entry, reference the specific array entry (e.g.,slider_images[0]
).
