Question

您好我已经创建了一个评论页面。当我按提交评论时，它会创建2条记录而不是1条而我无法理解它为何会这样做。

任何人都可以在我的代码中看到任何可能使其重复插入

的内容

<!-- Blog Comments -->

<?php
if(isset($_POST['create_comment'])) {
    $the_post_id = $_GET['p_id'];
    $comment_author = $_POST['comment_author'];
    $comment_email = $_POST['comment_email'];
    $comment_content = $_POST['comment_content'];

    if (!empty($comment_author) && !empty($comment_email) && !empty($comment_content)) {
        $the_post_id = $_GET['p_id'];

        $comment_author = $_POST['comment_author'];
        $comment_email = $_POST['comment_email'];
        $comment_content = $_POST['comment_content'];

        $query = "INSERT INTO comments(comment_post_id, comment_author,
                comment_email, comment_content,comment_status, comment_date)
                VALUES($the_post_id, '{$comment_author}',  '{$comment_email}',
                       '{$comment_content}','Unapproved' , now() )";

        $create_comment_query= mysqli_query($connection,$query);

        if(!$create_comment_query) {
            die('QUERY FAILED'. mysqli_error($connection));
        }

        /*  $query = "UPDATE posts SET post_comment_count = post_comment_count + 1 ";
        $query .= "WHERE post_id = $the_post_id ";  */

        $update_comment_count = mysqli_query($connection,$query);
    } else {
        echo "<script>alert('Fields cannot be empty')</script>";
    }
}

?>

<!-- Comments Form -->
<div class="well">
    <h4>Leave a Comment:</h4>
    <form role="form" action="" method="post">
         <div class="form-group">
              <label for="Author">Author :</label>

                 <input type="email" class="form_control"  name="comment_email">
         </div>
          <div class="form-group">
                 <label for="Comment">Your Comment :</label>
                <textarea class="form-control" rows="3" name="comment_content"></textarea>
         </div>
        <button type="submit" class="btn btn-primary" name="create_comment">Submit</button>
    </form>
</div>

Answer 1

在if if语句中，您有以下内容：

$create_comment_query = mysqli_query($conenction, $query);

然后你做：

$update_comment_count = mysqli_query($connection, $query);

我看到你评论了该查询应该更新的部分，但我猜这就是你遇到麻烦的原因。

因此，如果您删除应解决问题的$update_commment_count。如果这有帮助，请告诉我！

插入2条记录而不是1条记录
