过去几天我一直在研究这个问题。我希望代码实现的目标;有一个页面显示一定数量的缩写博客文章。然后，我希望在博客底部有一个链接到整篇文章的链接。我还想在完整的故事页面上找到一个链接，可以将您返回到缩写故事列表中。我试图使用SESSION id实现这一点，除了一件大事之外，几乎所有东西都有效。当显示整个博客的显示页面时，它会切断撇号或任何其他html特殊字符。我曾尝试使用htmlspecialchars ......但我无法弄明白。请帮忙。
我已经附上了我一直使用的三页。 1）检索信息的代码 2）运行循环的页面并显示缩写结果 3）显示整篇博客文章的完整故事页面
第一页/*$result = mysqli_query($cxn,$query)
or die("Couldn't execute query, Retard.");*/
// find out how many rows are in the table
$sql = "SELECT COUNT(*) FROM ashly";
$result = mysqli_query($conn, $sql)
or die("Could not connect, Dickhead");
$r = mysqli_fetch_row($result);
$_SESSION['numrows'] = $r[0];
##JH echo "{$_SESSION['numrows']} <br/><br>";
// number of rows to show per page
$_SESSION['rowsperpage'] = 4;
// find out total pages
$_SESSION['totalpages'] = ceil($_SESSION['numrows'] / $_SESSION['rowsperpage']);
##JH echo $_SESSION['totalpages'];
// get the current page or set a default
//if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
if (isset($_POST['currentpage']) && is_numeric($_POST['currentpage'])) {
// cast var as int
$_POST['currentpage'] = (int) $_POST['currentpage'];
} else {
// default page num
$_POST['currentpage'] = 1;
} // end if
// if current page is greater than total pages...
if ($_POST['currentpage'] > $_SESSION['totalpages']) {
// set current page to last page
$_POST['currentpage'] = $_SESSION['totalpages'];
} // end if
// if current page is less than first page...
if ($_POST['currentpage'] < 1) {
// set current page to first page
$_POST['currentpage'] = 1;
} // end if
// the offset of the list, based on current page
$_SESSION['offset'] = ($_POST['currentpage'] - 1) * $_SESSION['rowsperpage'];
// get the info from the db
$sql = " SELECT * FROM ashly ORDER BY id DESC LIMIT
{$_SESSION['offset']}, {$_SESSION['rowsperpage']} ";
$result = mysqli_query($conn, $sql) or die("Could not connect, connection Error");
// while there are rows to be fetched...
/*** this is where testPagingSESSION.inc goes. Has all loop and and page links
in it****/

答案 0 :(得分：0)
问题:(回声中有两个相同的引号，第一个在你的课堂上，第二个在你的课程中）
<h3 class='blog'>{$_SESSION['title']}</h3>
解决方案1：
<h3 class=\'blog\'>{$_SESSION['title']}</h3>
解决方案2：
使用stripslashes功能
