使用php和html跟踪/取消跟踪按钮
使用php和html跟踪/取消跟踪按钮
提问于 2017-12-09 20:53:12
我使用html/css和php为我的社交媒体wesbiste做了一个“跟踪取消跟踪”按钮。如果我没有跟随按钮应该打印跟随和我需要能够跟随他。如果我是跟随用户，按钮应该打印取消跟随，我应该取消跟随他。
<form>
<?php
if ($userid != $followerid) {
if ($isFollowing) {
echo '<input type="submit" name="unfollow" value="unfollow", style="width:100%;background-image:url("none");background-color:#da052b;color:#fff;padding:16px 32px;margin:0px 0px 6px;border:none;box-shadow:none;text-shadow:none;opacity:0.9;text-transform:uppercase;font-weight:bold;font-size:13px;letter-spacing:0.4px;line-height:1;outline:none>';
} else {
echo '<input type="submit" name="follow" value="Follow", style="width:100%;background-image:url("none");background-color:#da052b;color:#fff;padding:16px 32px;margin:0px 0px 6px;border:none;box-shadow:none;text-shadow:none;opacity:0.9;text-transform:uppercase;font-weight:bold;font-size:13px;letter-spacing:0.4px;line-height:1;outline:none>';
}
}
?>
</form>if (isset($_POST['follow'])) {
if ($userid != $followerid) {
if (!DB::query('SELECT follower_id FROM followers WHERE user_id=:userid AND follower_id=:followerid', array(':userid'=>$userid, ':followerid'=>$followerid))) {
if ($followerid == 6) {
DB::query('UPDATE users SET verified=1 WHERE id=:userid', array(':userid'=>$userid));
}
DB::query('INSERT INTO followers VALUES (null, :userid, :followerid)', array(':userid'=>$userid, ':followerid'=>$followerid));
} else {
echo 'Already following!';
}
$isFollowing = True;
}
}
if (isset($_POST['unfollow'])) {
if ($userid != $followerid) {
if (DB::query('SELECT follower_id FROM followers WHERE user_id=:userid AND follower_id=:followerid', array(':userid'=>$userid, ':followerid'=>$followerid))) {
if ($followerid == 6) {
DB::query('UPDATE users SET verified=0 WHERE id=:userid', array(':userid'=>$userid));
}
DB::query('DELETE FROM followers WHERE user_id=:userid AND follower_id=:followerid', array(':userid'=>$userid, ':followerid'=>$followerid));
}
$isFollowing = False;
}
}
if (DB::query('SELECT follower_id FROM followers WHERE user_id=:userid AND follower_id=:followerid', array(':userid'=>$userid, ':followerid'=>$followerid))) {
$isFollowing = True;
}当我按下按钮时，它会给我一个错误，用户发布的所有帖子都会消失，url将更改为：http://localhost/profile.php?unfollow=unfollow&postbody=&postimg=。

可能你的问题就在这里
<form>把它改成
<form action="somewhere.php" method="post">添加method="post“
