Pass id value from ahref to bootstrap modal php
提问by kya
I have a php code that creates a list from the database. One of the items I retrieve from the database is the row id. I create the list in the following code:
我有一个从数据库创建列表的 php 代码。我从数据库中检索的项目之一是行 ID。我在以下代码中创建列表：
<th>Cover Name</th>
<th>Sum Insured</th>
<th>Info</th>
<th style="width: 3.5em;"></th>
</tr>
</thead>
<tbody>
<?php while($row = mysql_fetch_array($query_set)) { ?>
<tr>
<td><?php echo $row['cover_name'] ?></td>
<td><?php echo 'R '.$row['sum_insured'] ?></td>
<td><?php echo $row['info'] ?></td>
<td>
<a href="cover-type.php?id=<?php echo $row['coverid']?>"><i class="fa fa-pencil"></i></a>
<a href="#myModal" onclick="<?php $coverid = $row['coverid'] ?>" role="button" data-toggle="modal"><i class="fa fa-trash-o"></i></a>
</td>
</tr>
<?php } ?>
</tbody>

The syntax for calling #myModal
调用的语法 #myModal
<a href="#myModal" onclick="<?php $coverid = $row['coverid'] ?>" role="button" data-toggle="modal"><i class="fa fa-trash-o"></i></a>
as you can see the anchor #myModaland onclick
正如你所看到的锚点#myModal和onclick
After clicking anchor I would like to pass $coveridto the following myModal pop up
单击锚点后，我想传递$coverid到以下 myModal 弹出窗口
<div class="modal small fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Delete Confirmation</h3>
</div>
<div class="modal-body">
<p class="error-text"><i class="fa fa-warning modal-icon"></i>Are you sure you want to delete the cover?<br>This cannot be undone.</p>
</div>
<div class="modal-footer">
<button class="btn btn-default" data-dismiss="modal" aria-hidden="true">Cancel</button>
<a href="delete-cover.php?id=<?php echo $coverid ?>" class="btn btn-danger" >Delete</a>
</div>
</div>
</div>
</div>
I under the impression that I need to have some form a hidden javascript variable in
我的印象是我需要某种形式的隐藏 javascript 变量
<a href="#myModal" onclick="<?php $coverid = $row['coverid'] ?>" role="button" data-toggle="modal"><i class="fa fa-trash-o"></i></a> and pass it to myModal window, but how do I do that ?

- uses a single modal
- use attribute data-id to store cover id:
data-id="< ?php $coverid = $row['coverid'] ?>" - add class to trash icon, for example
class="trash" - add id for Delete button in modal, for example
id="modalDelete"
- 使用单一模态
- 使用属性 data-id 来存储封面 ID：
data-id="< ?php $coverid = $row['coverid'] ?>" - 将类添加到垃圾桶图标，例如
class="trash" - 例如，在模态中为删除按钮添加 id
id="modalDelete"
and in JQ:
在 JQ 中：
// on clik trash icon
$('.trash').click(function(){
//get cover id
var id=$(this).data('id');
//set href for cancel button
$('#modallCancel').attr('href','delete-cover.php?id='+id);
})

PHP is executed on server while JavaScript is executed on client. This code
PHP 在服务器上执行，而 JavaScript 在客户端执行。这段代码
<a href="#myModal" onclick="<?php $coverid = $row['coverid'] ?>" role="button" data-toggle="modal">...</a>
will actually transform into
实际上会变成
<a href="#myModal" onclick="" role="button" data-toggle="modal">...</a>
because the PHP part didn't echo anything.
因为 PHP 部分没有回显任何内容。
So, you'll rather have to so something like this:
所以，你宁愿不得不这样做：
<a href="#myModal" onclick="show_dialog('<?php echo $row['coverid']; ?>')" role="button" data-toggle="modal">...</a>
Assuming you have PHP variable $rowdefined and $row['coverid']is, say, 1337, then this HTML will be rendered to browser:
假设您$row定义了PHP 变量并且$row['coverid']是 1337，那么此 HTML 将呈现给浏览器：
<a href="#myModal" onclick="show_dialog(1337)" role="button" data-toggle="modal">...</a>
thus, if you define JavaScript function show_dialog, it will get called with value from $row['coverid']. The only way to pass variables from PHP to JavaScript is to echo their values from PHP in the place where you have JavaScript code.
因此，如果你定义了 JavaScript 函数show_dialog，它会被调用的值为 from $row['coverid']。将变量从 PHP 传递到 JavaScript 的唯一方法是在您拥有 JavaScript 代码的地方从 PHP 回显它们的值。
A good practice for this is to use a <script>block somewhere on the top of your page with following content:
一个好的做法是<script>在页面顶部的某处使用一个包含以下内容的块：
window.php_vars = window.php_vars || {};
window.php_vars.some_value = '<?php echo $some_value; ?>';
window.php_vars.some_other_value = '<?php echo $some_other_value; ?>';
window.php_vars.foo = '<?php echo 'bar'; ?>';
...but this approach works only for scalar types (ints, strings etc).
...但这种方法仅适用于标量类型（整数、字符串等）。
