我如何获取要搜索的名称，以及如何在出现的结果中添加分页

Question

该列表仅停留在十个项目中，没有分页显示，可以得到其他列表的其余内容，这很糟糕，但是，谢谢你们，也许我需要更多的练习，我确实需要这个项目才能正常工作，以便我可以从任何一个项目中学习第一个代码起作用了，第二个起作用了，但是停在了十个项目上，您说尝试使用我已经使用的一些代码来执行ceil，下一个和后一个以及页面数出现了，但是没有列表，再次尝试了下一个和后一个，但是出现了十个项目，我在这里开始有些沮丧。

    <div class="results">

        error_reporting(0);
        if(isset($_POST['submit'])) {
            if(isset($_GET['go'])) {
                if(preg_match("/[A-Z | a-z]+/", $_POST['name'])){    //"/[A-Z | a-z]+/",
$name=$_POST['name'];

                //connect to the database
                $db=mysql_connect ("localhost", "root", "") or die ('I cannot connect to the database    because: ' . mysql_error()); 

                //-select the database to use
                $mydb=mysql_select_db("residential");

这是更改代码的开始

//////////pagination////////////

$sql=mysql_query("SELECT userId, FirstName, LastName FROM residentialbackup WHERE     FirstName ='" . $name . "' OR LastName = '" . $name ."'");

//-count results
$numrows=mysql_num_rows($sql);

// Get the value of the last page in the pagination result set
$lastPage = ceil($numrows / $itemsPerPage);

$itemsPerPage = 10;

$page = $_GET['page'];
if (!$page) $page = 1;
$offset = ($page - 1) * $itemsPerPage;

$sql2=mysql_query("SELECT userId, FirstName, LastName FROM residentialbackup WHERE    FirstName = '" . $name . "' OR LastName = '" . $name ."' LIMIT ". $offset . ", ".   $itemsPerPage);

$paginationDisplay = ""; // Initialize the pagination output variable
// This code runs only if the last page variable is ot equal to 1, if it is only 1 page     we require no paginated links to display
if ($lastPage != "1") {
    // This shows the user what page they are on, and the total number of pages
    $paginationDisplay .= 'Page <strong>' . $page . '</strong> of ' . $lastPage. '&nbsp;      &nbsp;  &nbsp; ';
    // If we are not on page 1 we can place the Back button
    if ($page != 1) {
        $previous = $page - 1;
        $paginationDisplay .=  '&nbsp;  <a href="' . $_SERVER['PHP_SELF'] . '?page=' . $previous . '"> Back</a> ';
    } 
    // Lay in the clickable numbers display here between the Back and Next links
$paginationDisplay .= '<span class="paginationNumbers">' . $centerPages . '</span>';
    // If we are not on the very last page we can place the Next button
    if ($page != $lastPage) {
        $nextPage = $page + 1;
        $paginationDisplay .=  '&nbsp;  <a href="' . $_SERVER['PHP_SELF'] . '?page=' .   $nextPage . '"> Next</a> ';
    } 
}

echo $paginationDisplay;
///////////////pagination end////////////

我坚持到这里！

            echo "</ul>";
        }
    }
    else { 
        echo "<p>Please enter a search query</p>";
    }
}

您的查询中包含通配符，请将其删除以仅获取完全匹配项

$sql="SELECT userId, FirstName, LastName FROM residentialbackup WHERE FirstName ='" . $name . "' OR LastName = '" . $name ."'";

您可以像这样进行分页：

$itemsPerPage = 10;
$page = $_GET['page'];
if (!$page) $page = 1;
$offset = ($page - 1) * $itemsPerPage;

$sql="SELECT userId, FirstName, LastName FROM residentialbackup WHERE FirstName = '" . $name . "' OR LastName = '" . $name ."' LIMIT ". $offset . ", ". $itemsPerPage;
