我在php中遇到get方法的问题,我尝试从一个php页面到另一个php页面获取一个变量($ profile_id),该变量在这个页面中工作
<?php
$follow="";
$loggedinid=$_SESSION['userid'];
$sqll = "SELECT id FROM Follow WHERE user_one='$loggedinid' AND user_two='$profile_id'";
if($profile_id != $_SESSION["userid"]){
$check= mysqli_query($db_conx, $sqll);
if(mysqli_num_rows($check) == 1){
$follow='<a href="followaction.php?followaction=unfollow&profid=$profile_id">Unfollow</a>';//This is where i try to put the variable, so i can call it with the get method on followaction.php
}else{
$follow='<a href="followaction.php?followaction=follow&profid=$profile_id">Follow</a>';
}
}
?>
然后在followaction.php中,当我调用profid时,它返回$ profile_id(sting)而不是它应该代表的数字
<?php
include_once("php_includes/check_login_status.php");
$followaction=$_GET['followaction'];
$profileid = $_GET['profid'];
$loggedinid = $_SESSION['userid'];
$loggedinusername = $_SESSION['username'];
if($followaction == 'follow'){
mysqli_query($db_conx, "INSERT INTO Follow VALUES('','$loggedinid','$profileid')");
}
if($followaction == 'unfollow'){
$sql = "DELETE FROM Follow WHERE user_one='$loggedinid' AND user_two='$profileid'";
mysqli_query($db_conx, $sql);
}
?>
我如何解决这个问题,一切正常,但我无法将profile_id传输到此页面....
答案 0 :(得分:0)
这不起作用
$follow='<a href="followaction.php?followaction=unfollow&profid=$profile_id">Unfollow</a>';
如果你这样做
echo $follow;
你会得到这样的东西(注意$ profile_id没有被替换)
<a href="followaction.php?followaction=unfollow&profid=$profile_id">Unfollow</a>
如果您想要变量替换
,则需要使用双引号 $follow="<a href=\"followaction.php?followaction=unfollow&profid=$profile_id\">Unfollow</a>";
