我创建了一个页面，它从寄存器页面获取所有数据。我为所有页面放置了按钮。一旦我单击一个按钮，所有按钮都会更改为发送的请求，我遇到问题。我不知道这是怎么发生的。
<?php
session_start();
$_SESSION['myid'];
$mysqli=new MySQLi('127.0.0.1','root','','learning_malaysia');
$sql = "SELECT * FROM tutor_register INNER JOIN tutorskill ON tutor_register.register_ID = tutorskill.register_ID ORDER BY
tutor_register.register_ID='".$_SESSION['myid']."'desc";
$result= mysqli_query($mysqli,$sql);
?>
<html>
<title>friend</title>
<head>
</head>
<body>
<?php
if(mysqli_num_rows($result)>0)
{
while($row = mysqli_fetch_array($result))
{
$register_ID=$row["register_ID"];
$username = $row['username'];
$profile = $row['profile'];
$email = $row['email'];
$address=$row['address'];
$gender=$row['gender'];
$main_subject=$row["main_subject"];
$subject_add=$row["subject_add"];
$rate_main=$row["rate_main"];
$rate_add=$row["rate_add"];
$qualification=$row["qualification"];?>
<table><form method="post">
<tr class="border_bottom">
<td height="230"><img src='<?php echo $profile;?>'width="200" height="200"/> </td><td><td></td></td>
<td class="data" width="800"><strong>Username:</strong> <?php echo $username;?></br>
<strong>Address:</strong> <?php echo $address;?></br>
<strong>Gender:</strong><?php echo $gender;?></br>
<strong>Main Subject:</strong><?php echo $main_subject ;?></br>
<strong>Subject Added: </strong><?php echo $subject_add;?></br>
<strong>Main Subject Rate:</strong> <?php echo $rate_main;?></br>
<strong> Added Subject Rate:</strong><?php echo $rate_add; ?></br>
<strong>Qualification:</strong> <?php echo $qualification; ?></td>
<?php
if($register_ID == $_SESSION['myid']){
?>
<td><label>Your Profile</label></td>
<?php
} else {
?>
<form method="post">
<td><button class='friendBtn unfriend' name="" data-type="unfriend">Unfriend</button>
<input type="hidden" name="id" value="<?php echo $row['register_ID'];?>" />
<input type="submit" name="addfriend" data-type='addfriend' id="addfriend" value="<?php
if($_SESSION['status'] == 'yes'){
echo 'Request Sent';
}
else {
echo 'Addfriend';}
?>" data-uid=<?php echo $row['register_ID'];?>/></td> </form>
</td>
<?php
}
}
?>
</tr>
</div>
</table>
</form>
<?php
if(isset($_POST['id']) ) {
$user_id = $_SESSION['myid'];
$friend_id = $_POST['id'];
$sql="INSERT INTO friends(user_id,status,friend_id)" ."VALUES('$user_id','yes','$friend_id') ";
if($mysqli->query($sql)=== true) {
$_SESSION['status']="yes";
$_SESSION['id']=$row['id'];
} else {}
}
}
?>
</body>
</html>
最佳答案
请参阅下面添加的条件$row['register_ID']==$_SESSION['id']。这将解决您的问题。
<form method="post">
<td><button class='friendBtn unfriend' name="" data-type="unfriend">Unfriend</button>
<input type="hidden" name="id" value="<?php echo $row['register_ID'];?>" />
<input type="submit" name="addfriend" data-type='addfriend' id="addfriend" value="<?php
if($_SESSION['status'] == 'yes' && $row['register_ID']==$_SESSION['id']){
echo 'Request Sent';
}
else {
echo 'Addfriend';}
?>" data-uid=<?php echo $row['register_ID'];?>/>
</td>
</form>
