Question

我正在我的网站上使用wordpress查看并更改用户的封面，点击照片，然后将其重定向到例如process.php?pid=12

我正在使用

switch($GetPicId)
{

所以我无法添加更多图片，但现在我有使用数据库上传图片的脚本，我想通过使用数据库获取id和pic位置

首先这是upload script

这是切换代码

    $GetPicId = $_GET["pid"]; // Picture ID from Index page
$PicLocation ='';

/*
Users do not need to know original location of image.
I think it's better to get image location from database using ID.
for demo here i'am using PHP switch.
*/
switch($GetPicId)
{
    case 1:
        $PicLocation = 'cover_pics/cover1.jpg';
        break;
    case 2:
        $PicLocation = 'cover_pics/cover2.jpg';
        break;
    case 3:
        $PicLocation = 'cover_pics/cover3.jpg';
        break;
    case 4:
        $PicLocation = 'cover_pics/cover4.jpg';
        break;
    case 5:
        $PicLocation = 'cover_pics/cover5.jpg';
        break;
    case 6:
        $PicLocation = 'cover_pics/cover6.jpg';
        break;
    case 7:
        $PicLocation = 'cover_pics/cover7.jpg';
        break;
    case 8:
        $PicLocation = 'cover_pics/cover8.jpg';
        break;
    case 9:
        $PicLocation = 'cover_pics/cover9.jpg';
        break;
    case 10:
        $PicLocation = 'cover_pics/cover10.jpg';
        break;
    case 11:
        $PicLocation = 'cover_pics/cover11.jpg';
        break;
    default:
        header('Location: ' . $homeurl);
        break;
}

Answer 1

使用它来获取附件网址。您的封面图片是否已上传到媒体中？

然后试试这个

<?php wp_get_attachment_url( $id ); ?>

它会变成这样的东西

 $GetPicId = $_GET["pid"]; // Picture ID from Index page

 $PicLocation =wp_get_attachment_url( $GetPicId);

Answer 2

试试

$GetPicId = $_GET["pid"]; // Picture ID from Index page
$sql=mysql_query("SELECT piclocation FROM tableName WHERE pid=$GetPicId") or die(mysql_error());
$res=mysql_fetch_array($sql);

$PicLocation = $res['piclocation '];
