如何在laravel的编辑页面中从db获取json值

嗨，伙计们，我有多个部分的表单，所以在插入时，我会存储我所选择的特定部分。所以我将这些值以json格式存储在db中。现在我只想在我的编辑页面中获取这些特定部分的值

以下是我存储所有json代码的函数：

function toggler(section_value, from_where)
{
    var html_question_section         = '';
    var html_question_section_display = '';
    var section_counter               = 0;

    if(from_where == 'question')
    {
        question_section_counter += 1;
    }
    else if(from_where == 'solution')
    {
        soution_section_counter += 1;
    }

    if(section_value == 'text_section')
    {
        question_text_section_counter += 1;
        section_counter = question_text_section_counter;
    }
    else if(section_value == 'image_section')
    {
        question_image_section_counter += 1;
        section_counter = question_image_section_counter;
    }
    else if(section_value == 'sol_text_section')
    {
        soution_text_section_counter += 1;
        section_counter = soution_text_section_counter;
    }
    else if(section_value == 'sol_text_chk_section')
    {
        soution_text_chk_section_counter += 1;
        section_counter = soution_text_chk_section_counter;
    }
    else if(section_value == 'sol_image_chk_section')
    {
        soution_img_chk_section_counter += 1;
        section_counter = soution_img_chk_section_counter;
    }
    else if(section_value == 'sol_text_radio_section')
    {
        soution_text_radio_section_counter += 1;
        section_counter = soution_text_radio_section_counter;
    }
    else if(section_value == 'sol_image_radio_section')
    {
        soution_img_radio_section_counter += 1;
        section_counter = soution_img_radio_section_counter;
    }

    html_question_section         =  getSectionHtml(section_value, section_counter, from_where);
    html_question_section_display =  getSectionDisplay(section_value, section_counter);
    template_json                 =  getTemplateJSON(section_value, from_where);

    if(from_where == 'question')
    {
        $('#div_question_section').append(html_question_section);
        $('#div_display_question_section').append(html_question_section_display);
    }
    else
    {
        $('#div_solution_section').append(html_question_section);
        $('#div_display_solution_section').append(html_question_section_display);
    }

    var json_string = JSON.stringify(template_json, undefined, 2);
    $('.json_template').html(json_string).val(json_string);
}

以下是我的控制器代码：

    $template->template_json = json_encode($request->input('json_template'));

谁能帮助我如何在编辑页面中获取这些值。取决于我应该获取的索引
