您好我想将从数据库中检索到的$ id的值传递给模态，因此我可以在更新图像时将其用作Where子句。

这是我的第一个问题，希望有人会回答

        <a href="" data-toggle="modal" class="update_pic" data_id = "$id" data-target="#update-modal">
            <img height="100px" width="100px" src="data:image/jpeg;base64,'.base64_encode( $row['pestImage'] ).'"/>
        <a/>
    </td>
    <td><?php echo $imagedesc.''.$id;?></td>
    <td><?php echo $pestname;?></td>
    <td><?php echo $pesticide;?></td>
    <td>
        <a class='editClass' href="#form_modal" data-toggle="modal" data-id="<?echo $id;?>">
                Edit
        </a>
        <form action='../php/deletepest.php?id=$id' method='POST'>
            <button class='btn btn-danger btn-sm btn-block'>Delete</button>
        </form>
    </td>
</tr>

<强> JS

<script>
$('.editClass').click(function(){
    var id=$(this).attr('data-id');
    $.ajax({url:"editpest.php?id="+id,cache:false,success:function(result){
        $(".modal-content").html(result);
    }});
});
</script>

页脚（将此代码放在页脚或<table></table>下方

<div class="modal fade" id="form_modal" tabindex="-1" role="dialog">
  <div class="modal-dialog">
    <div class="modal-content">

    </div>
  </div>
</div>

editpest.php

<?php
$id = $_GET['id'];
// Now, write your query here
?>

<div class="modal-header">
  <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
  <h4 class="modal-title">Update</h4>
</div>
<div class="modal-body">
    .
    .
    <?php echo "Id: ".$id;?>
    .
    .   
   // Write code here to update

</div>
<div class="modal-footer">
  <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
