Question

i need to pass jquery ID value in to my est_model->get_img() function in codeigniter and display all the content in the same modal box, i tried my own logic it doesn't work, please help guys, thank you in advance

here is my code below: modal a tag:

<a href="#view_all_img_modal" data-toggle="modal" data-est-id="<?php echo $row->est_id;?>">View all</a>

my jquery:

$('#view_all_images_modal').on('show.bs.modal', function(e) {
    var est_id = $(e.relatedTarget).data('est-id');
    $.ajax({url:"admin/est_view.php?ID="+est_id,cache:false,success:function(result){
        $("#view_all_img_modal").html(result);
    }});

});

modal box:

<div class="modal fade" id="view_all_img_modal" tabindex="-1" role="dialog">
<div class="row">
    <?php
        $id=$_GET['ID'];
            $est_img=$this->est_model->get_img($id);
            if($est_img):
                foreach ($est_img as $img):
                $ser_img=($img->img_name==NULL)?'no-image.png':$img->img_name;?>
                    <img src="<?php echo base_url('../public/images/rel_img/'.$ser_img);?>">
