toolbox/helpers/set_acfimage_classes
Sets the default classes for the ACF image field when adding it with an img- tag.
The classes can be added using the filter, or by adding a filter that enables an attribute to pass in the classes.
Parameters
$classes(array)$attr(string)
Usage
If the classes defining the image aren’t enough for you you can always add more. This example adds a new attribute and function so that you can add classes using the toolbox shortcode.
<?php
add_filter( 'toolbox/helpers/sc_attr/type=image' , 'add_image_class_attr' , 10 ,1 );
// add a custom attribute named 'myclass'
function add_image_class_attr( $attr ) {
$attr['myclass'] = '';
return $attr;
}
add_filter( 'toolbox/helpers/set_acfimage_classes' , 'enable_custom_image_classes', 10, 2 );
// add the custom atrtibute 'myclass' to the $classes array
function enable_custom_image_classes( $classes , $attr ) {
if (isset($attr['myclass']) && $attr['myclass'] !='' ) {
array_push( $classes , $attr['myclass'] );
}
return $classes;
}You can now add classes with extra classes using the shortcode:
[toolbox field='imagefield' tag='true' size='thumbnail' myclass='mycustomclass']
