Yii2 wbraganca, File Input (Kartik), dynamic forms

Question

Not loaded next preloader and image after insert image in dynamic form item. Correct load image in case I didn't load image yet. In case I load image, next preloader not load in next dynamicform item and I don't save next images

Answer 1

found one of solution, may be not better, but nearly normal state. Problem was here

identifiers[i] = $elem.closest(widgetsOptions[i].widgetItem).index();

if replace this by this:

if(typeof widgetsOptions[i] !== 'undefined'){

identifiers[i] = $elem.closest(widgetsOptions[i].widgetItem).index(); }

problem was resolved, but not perfectly. After Add new item, preload image loaded correct and I could upload image, but load first item which was has loaded earlier.
