从codeigniter中获取动态表单中的值

Question

我有一个用以下代码编写的动态表单，我试图获取表单中的所有详细信息。我该怎么做呢？

表格

<?php echo form_open_multipart('backendProduct/save_product'); ?>
    <div class="row"  ng-app="appcolor">
<div id="gc_photos"></div>
    </div>
</form>

<script type="text/template" id="imageTemplate">
    <div class="row gc_photo" id="gc_photo_{{id}}" style=" border-bottom:1px solid #ddd; padding-bottom:20px; margin-bottom:20px;">
        <div class="col-md-2">
            <input type="hidden" name="images[{{id}}][filename]" value="{{filename}}"/>
            <img class="gc_thumbnail" src="<?php echo base_url('../product_images/{{filename}}');?>" style="padding:5px; border:1px solid #ddd"/>
        </div>
        <div class="col-md-10">
            <div class="row">
                <div class="col-md-4">
                    <div class="form-group">
                        <input name="images[{{id}}][alt]" value="{{alt}}" class="form-control" placeholder="<?php echo lang('alt_tag');?>"/>
                    </div>
                </div>
                <div class="col-md-4">
                    <div class="checkbox">
                        <label>
                            <input type="radio" name="primary_image" value="{{id}}" {{#primary}}checked="checked"{{/primary}}/> <?php echo lang('main_image');?>
                        </label>
                    </div>
                </div>
                <div class="col-md-4">
                    <a onclick="return remove_image($(this));" rel="{{id}}" class="btn btn-danger pull-right"><i class="icon-times "></i></a>
                </div>
            </div>
            <div class="row">
                <div class="col-md-12">
                    <label><?php echo lang('caption');?></label>
                    <textarea name="images[{{id}}][caption]" class="form-control" rows="3">{{caption}}</textarea>
                </div>
            </div>
        </div>
    </div>
</script>

功能

function addProductImage(val)
{
    view = {
        id:val.item_id,
        filename:val.detail_image_name,
        alt:val.alt,
        primary:val.primary,
        caption:val.caption
    }

    var output = Mustache.render(imageTemplate, view);

    $('#gc_photos').append(output);
    $('#gc_photos').sortable('refresh');
    photos_sortable();
}
