php - 将从 mysql 数据库收集的 SESSION 变量发布到新页面

Question

最近几天我一直在研究这个问题。我希望代码实现什么；有一个页面显示一定数量的简短博客文章。然后我想在博客底部有一个链接到整篇文章的链接。我还想要一个完整故事页面上的链接，可以让您返回到缩略故事列表。我已经尝试使用 SESSION id 来实现这一点，并且除了一件主要的事情之外，几乎所有的东西都在工作。当显示整个博客的显示页面时，它会在撇号或任何其他 html 特殊字符处截断。我曾尝试使用 htmlspecialchars...但我就是想不通。请帮忙。

我在下面附上了我一直在使用的三页。 1)检索信息的代码 2)运行循环并显示缩略结果的页面 3) 显示整篇博客文章的全文页面

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****/

##JH was: commented out for TESTING include("ashlyBlog2.inc"); 
                                include("ashlyBlogTESTING.inc");  // this include 
uses    the character control function
                                ?>

Answer 1

问题:(你在 echo 中有两个相同的引号，第一个在你的类里面，第二个在你的 session 中)

<h3 class='blog'>{$_SESSION['title']}</h3>

解决方案一:

<h3 class=\'blog\'>{$_SESSION['title']}</h3>

解决方案 2:

使用stripslashes功能
