我有一个用 Mysql 编写的脚本，它只列出人名。它在 mysql 中工作正常，但我一直试图让它更新到 mysqli，我得到了大部分。但是，结果应该是分页的。分页工作正常，因为应该有 5 页，这就是它停止的地方......但所有结果都显示在每一页上。不确定我在做什么...任何帮助将不胜感激....我知道它与“mysql_result”有关
这是我在 mysqli 中的新代码:
<?php
include ('paginate.php'); //include of paginat page
$per_page = 10; // number of results to show per page
$result = $con->query("SELECT EmployeeID,FirstName,LastName FROM employee;");
//If Database Error...Print the error and exit
if (!$result) {
printf("Error: %s\n", mysqli_error($con));
exit();
}
//If No Database Error.....Continue
if ($result)
{
// Return the number of rows in result set
$total_results=mysqli_num_rows($result);
//printf("Result set has %d rows.\n",$total_results);
// Free result set
}
//total pages we going to have
$total_pages = ceil($total_results / $per_page);
//if page is setcheck
$show_page='';
if (isset($_GET['page'])) {
$show_page = $_GET['page'];//it will telles the current page
if ($show_page > 0 && $show_page <= $total_pages) {
$start = ($show_page - 1) * $per_page;
$end = $start + $per_page;
} else {
// error - show first set of results
$start = 0;
$end = $per_page;
}
} else {
// if page isn't set, show first set of results
$start = 0;
$end = $per_page;
}
// display pagination
$page = intval(isset($_GET['page']));
$tpages=$total_pages;
if ($page <= 0)
$page = 1;
?>

这是我在 mysql 中的原始代码:
<?php
error_reporting(E_ALL | E_NOTICE);
ini_set('display_errors', '1');
error_reporting(E_ALL ^ E_DEPRECATED);
include('config.php'); //include of db config file
include ('paginate.php'); //include of paginat page
$per_page = 10; // number of results to show per page
$result = mysql_query("SELECT * FROM employee");
$total_results = mysql_num_rows($result);
$total_pages = ceil($total_results / $per_page);//total pages we going to have
//-------------if page is setcheck------------------//
$show_page='';
if (isset($_GET['page'])) {
$show_page = $_GET['page']; //it will telles the current page
if ($show_page > 0 && $show_page <= $total_pages) {
$start = ($show_page - 1) * $per_page;
$end = $start + $per_page;
} else {
// error - show first set of results
$start = 0;
$end = $per_page;
}
} else {
// if page isn't set, show first set of results
$start = 0;
$end = $per_page;
}
// display pagination
$page = intval(isset($_GET['page']));
$tpages=$total_pages;
if ($page <= 0)
$page = 1;
?>

我在这里做错了，我想不通....
任何帮助将不胜感激......
非常感谢。
最佳答案
我也将删除 while 语句并结合使用 mysqli_data_seek 和 mysqli_fetch_accoc。 MySQLi_data_seek 指向我需要的结果。检查一下:
// display data in table
echo "<table class='table table-bordered'>";
echo "<thead><tr><th>First
Name</th> <th>Last Name</th></tr></thead>";
// loop through results of database query, displaying them in the table
// loop through results of database query, displaying them in the table
for ($i = $start; $i < $end; $i++) {
// make sure that PHP doesn't try to show results that don't exist
if ($i == $total_results) {
break;
}
//go to the column you want the results
mysqli_data_seek($result, $i);
$row = mysqli_fetch_assoc($result);
// echo out the contents of the row into a table
echo "<tr>";
echo '<td>' . $row['FirstName'] . '</td>';
echo '<td>' . $row['LastName'] . '</td>';
echo "</tr>";
}
}
echo "</table>";
