仅操作foreach循环的第一行并同时操作所有行

I am trying to add a delete button which is only visible for Admin. But at the same time, the first row would have a 'I have read this information' button for the users. On this code the delete button cannot be hidden for all rows. The delete button gets only hidden for the first row. I want the delete button not appear anywhere if the user is not an administrator.

I have tried this javascript code but it affects only the first row of my foreach loop. I have no idea what to do. Do you have any idea?

 <?php     if(($_SESSION['username'] == 'Admin')) { 

    echo "<script>  $('#del_photo').hide(); </script> ";
    }




                foreach($select as $index => $rs) {


    ?>    

                <div class="post-id"   id="<?php echo $rs['id']; ?>" style="margin 300px; overflow: hidden; border-top-right-radius: 25px; border-top-left-radius: 25px;   display:block;
                position: relative; margin: 20px; border: 2px solid #222;">
                <br><br>
                <h2 class="blog-post-title"><?php echo $rs['title'];?></h2>
                <p class="blog-post-meta"> <?php echo $rs['date'];?> skrevs av <a href="#"> <?php echo $rs['author'];?></a></p>

                        <?php 
                            $i = 0;
                            $len = count($select);
                            foreach ($select as $item) {
                            if ($i == 0) {
                            echo  "<form action=\"#\" style=\" height:30px; background:transparent; border:none; color:transparent;\" method=\"get\"> <button name=\"readit\" id=\"readit\" 
                            style=\" height:30px; position:absolute; background:transparent; border:none; color:transparent; width:70px;  display: flex; top:-0.5%; left:0%; float:right; margin:5px 5px 0 0;\"  
                            class=\"del_photo\"> <span src=\"sett.png\" class=\"readit\" id=\"readit\" ></span><img src=\"sett.png\"  class=\"readit\"  border=\"0\" /></button> </form>";
                            } else if ($i == $len - 1) {
                            echo "// last";
                            }

                            $i++;
                            }   
                        ?>

    The problem is that you telling jquery to hide the button with the id="del_photo"

    but an id is means to be unique so that won't work in that case and only hide the first one, so you better use the class del_photo

    so try

    echo "<script> $('.del_photo').hide(); </script> ";
