我包含一个下拉菜单和按钮,可以使用php删除数据库中的行。 下拉框(博客文章标题)中显示的值不是主键,sql delete函数仅适用于主键。如何将id传递给sql查询但仍然显示博客文章的标题?
(是的,我确实有与数据库的连接)
<?php
$delete = $_POST['delete_submit'];
mysql_query("DELETE FROM blogpost WHERE BlogPostID=$delete");
?>
<section style="font-size: 22px; text-align: center;">
<form action='admin.php' method='post' onsubmit="return confirm('Do you really want to delete this post?');">
<p>
Delete Post:
<select name="delete">
<option>Please select a post</option>
<?php
$result = mysql_query("SELECT BlogPostID, BlogPostTitle FROM blogpost ORDER BY BlogPostID DESC");
while ($row = mysql_fetch_array($result)){
$blogvar = array($row ['BlogPostID'], $row ['BlogPostTitle']);
?>
<option><?php echo $blogvar[1]; ?></option>
<?php
};
?>
</select>
<p></p>
<input type='submit' class='button' name='delete_submit' value='Delete'/>
</p>
</form>
</section>

您只需将值放在<option>
中,如下所示:
<option value="1">Volvo</option>
然后在显示名称的同时发送1(或您的ID)。
<option value="<?php echo $blogvar[0]; ?>"><?php echo $blogvar[1]; ?></option>
