Repopulating checkboxes in Codeigniter after Unsuccessful Form Validation

Question

I have a problem repopulating a set of checkboxes after an unsuccessful form validation returns the user back to the same form. Dropdown menus and text inputs could be repopulat

Answer 1

I tried all the solutions here none worked. So i collected all the data, packed it into an array, then use a loop to check if the values in the array match the value of the selected box, if so change the checked attribute to checked.

Here is the html code:

    
        Love                            
    
    
        God
    
    
        Reality
    
    
        Entrepreneurship
    

Here is the javascript code in a function

(function(){
    var tag_string = '',
        tags = tag_string.split(', ');
    boxes = document.getElementsByClassName('tags');
    for(i = 0; i< boxes.length;i++ ){
        if(tags.toString().includes(boxes[i].value)){
            boxes[i].checked = "checked";
        }
    }
})();
