Question

我是php的新手，请保持温柔。我在这个论坛中找到了关于完全相同的问题的解决方案，但有些困惑。我似乎无法弄清楚为什么会出错

在第10行中调用未定义的函数mysqli_result（）

发生吉普车。

任何人都可以帮忙

<?php
include 'connection.php';
$per_page = 10;

$pages_query = mysqli_query($con,"SELECT COUNT('uniqueID') FROM 'business'");
$pages = mysqli_result($pages_query, 0) / $per_page;

$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$start = ($page - 1) * $per_page;

$query = mysqli_query($con,"SELECT 'manu' FROM 'business' LIMIT $start  $per_page");
while ($query_row = mysqli_fetch_assoc($query)) {
echo '<p>', $query_row['manu'] ,'</p>';
}
?>

Answer 1

尝试这样

<?php
include 'connection.php';
$per_page = 10;

$pages_query = mysqli_query($con,"SELECT COUNT('uniqueID') FROM 'business'");
$result = mysqli_fetch_row($pages_query); // <----- added
$pages = $result[0] / $per_page; // <------- modified

$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$start = ($page - 1) * $per_page;

$query = mysqli_query($con,"SELECT 'manu' FROM 'business' LIMIT $start  $per_page");
while ($query_row = mysqli_fetch_assoc($query)) {
echo '<p>', $query_row['manu'] ,'</p>';
}
?>

Answer 2

<?php
include 'connection.php';
$per_page = 10;

$pages_query = mysqli_query($con,"SELECT COUNT('uniqueID') FROM 'business'");
$result = mysqli_fetch_row($pages_query); // <----- added
$pages = $result[0] / $per_page; // <------- modified

$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$start = ($page - 1) * $per_page;
$query = mysqli_query($con,"SELECT 'manu' FROM 'business' LIMIT $start  $per_page");
while ($query_row = mysqli_fetch_assoc($query)) {

echo '<p>'. $query_row['manu'] .'</p>';

}
?>
