嗨，我想弄清楚这是否会在某种意义上起作用。现在当然不是。我现在抛出错误，但我也没有得到任何使用 $nextLink 变量输出的东西。
这是完整的，所以我们很清楚它们是如何结合在一起的：
<?php
// Check to see the URL variable is set and that it exists in the database
if (isset($_GET['id'])) {
// Connect to the MySQL database
include "includes/db_conx.php";
$id = intval($_GET['id']);// filter everything but numbers
// Use this var to check to see if this ID exists, if yes then get the product
// details, if no then exit this script and give message why
$sql = "UPDATE content SET views=views+1 WHERE ID=$id";
$update = mysqli_query($db_conx,$sql);
$sql = "SELECT * FROM content WHERE id=$id LIMIT 1";
$result = mysqli_query($db_conx,$sql);
$productCount = mysqli_num_rows($result);
//
if ($productCount > 0) {
// get all the product details
while($row = mysqli_fetch_array($result)){
$id = $row["id"];
$article_title = $row["article_title"];
$category = $row["category"];
$readmore = $row["readmore"];
$author = $row["author"];
$date_added = $row["date_added"];
$article = $row["article"];
$newDate = substr($date_added, 0, 10);
}
} else {
echo "That item does not exist.";
exit();
}
} else {
echo "Data to render this page is missing.";
exit();
}
$sqltwo = "SELECT * FROM content WHERE id =(select min(id) from content where id > '$id') LIMIT 1";
$next = mysqli_query($db_conx,$sqltwo);
if($next > 0){
while($row = mysqli_fetch_array($next)){
$id = $row["id"];
$nextLink = '$id';
}
}
?>
这是我正在处理的片段。
$sqltwo = "SELECT * FROM content WHERE id =(select min(id) from content where id > '$id') LIMIT 1";
$next = mysqli_query($db_conx,$sqltwo);
if($next > 0){
while($row = mysqli_fetch_array($next)){
$id = $row["id"];
$nextLink = '$id';
}
}
我试图通过在当前 id 之后抓取一堆并选择下一个来为 HTML 提供 $nextLink 来选择下一行。
这是我 $next 的 vardump
object(mysqli_result)#3 (5) {
["current_field"]=>
int(0)
["field_count"]=>
int(10)
["lengths"]=>
NULL
["num_rows"]=>

["type"]=>
