The logic on line 225 is bad.
if(
isset($wp_logo_slider_images['update']) == 'Added'
|| $wp_logo_slider_images['update'] == 'Deleted'
|| $wp_logo_slider_images['update'] == 'Updated') {
isset($wp_logo_slider_images['update']) is never going to equal ‘Added’ but that isn’t where the error comes in. PHP will try to use $wp_logo_slider_images['update'] twice on that line without checking that the value is set.
What you need is:
if(
isset($wp_logo_slider_images['update'])
&& (
$wp_logo_slider_images['update']== 'Added'
|| $wp_logo_slider_images['update'] == 'Deleted'
|| $wp_logo_slider_images['update'] == 'Updated'
)
) {
Notice the extra set of () to group the ||s and make sure that PHP does not try to access $wp_logo_slider_images['update'] if it isn’t set.
