【问题描述】:
我希望将以下 php 表单提交转换为 JQuery Ajax 提交。我之前使用过 Ajax 和一些简单的请求,但我不确定如何从 MySQL 提交和返回以下代码的数据。
下面的代码将用户输入条目提交给返回单列行的 MySql 查询。然后一个 While 循环查看这些行并触发另一个 mysql 查询,返回每行的用户喜欢数。
<?php
if(!empty($_POST['Message']))
{
$userid = session_id();
$searchStr = get_post($con,'Message');
$aKeyword = explode(" ", $searchStr);
$aKeyword = array_filter($aKeyword);
$stmt = $con->prepare(
'SELECT m.ID, m.MessageText
FROM MessageMain m
LEFT OUTER JOIN Likes l on m.ID = l.PostID
WHERE MessageText REGEXP ?
GROUP BY m.ID, m.MessageText ORDER BY count(m.id) desc'
);
$regexString = implode('|', $aKeyword);
$stmt->bind_param('s', $regexString);
$stmt->execute();
$result = $stmt->get_result();
$rowcount=mysqli_num_rows($result);
echo "<pre> Returned ". $rowcount . " matches</pre>";
if(mysqli_num_rows($result) > 0) {
$row_count=0;
While($row = $result->fetch_assoc()) {
$postid = $row['ID'];
$row_count++;
// Checking user status
$status_query = $con->prepare("SELECT COUNT(*) AS type FROM likes WHERE userid = ? AND postid = ?");
$status_query->bind_param('ss',$userid,$postid);
$status_query->execute();
$status_result = $status_query->get_result();
$status_row = $status_result->fetch_assoc();
$type = $status_row['type'];
// Count post total likes
$like_query = $con->prepare("SELECT COUNT(*) AS cntLikes FROM likes WHERE postid = ?");
$like_query->bind_param('s',$postid);
$like_query->execute();
$like_result = $like_query->get_result();
$like_row = $like_result->fetch_assoc();
$total_likes = $like_row['cntLikes'];
?>
<div class="post">
<div class="post-text">
<?php
echo nl2br(htmlentities($row['MessageText'],ENT_COMPAT|ENT_IGNORE, "UTF-8") );
?>
</div>
<div class="post-action">
<input type="button" value="Like" id="like_<?php echo htmlentities($postid . "_" . $userid); ?>" class="like" style="<?php if($type == 1){ echo "color: #ffa449;"; } ?>" /> (<span id="likes_<?php echo $postid . "_" . $userid; ?>"><?php echo htmlentities($total_likes); ?></span>)
</div>
</div>
<?php
}
}
}
