使用表单变量重定向无法正常工作

Question

我在文件（search.php）上使用了如下接收的变量：

session_start();
if (isset($_POST['Search'])){
    $_SESSION['Search'] = $_POST['Search'];
}

表格：

<form id="searchbox" action="/search.php" method="post">
      <input id="search" name="Search" type="text" placeholder="Search Products">

  <input id="submit" type="submit" value="Search" ></form>

所以它顺服于自己

我有以下重定向：

rewritecond %{THE_REQUEST} \s/+search\.php? [NC]
rewriterule ^ /Search/? [R=301,L]
rewritecond %{REQUEST_FILENAME} !-d
rewritecond %{REQUEST_FILENAME} !-f
rewriterule ^Search/?$ /search.php? [L,QSA]

rewritecond %{THE_REQUEST} \s/+search\.php\?pageNum_RS_Search=([^\s&]+)&totalRows_RS_Search=([^\s&]+) [NC]
rewriterule ^ /Search/%2/%1? [R=301,L]
rewritecond %{REQUEST_FILENAME} !-d
rewritecond %{REQUEST_FILENAME} !-f
rewriterule ^Search/([^/]+)/([^/]+)/?$ /search.php?pageNum_RS_Search=$2&totalRows_RS_Search=$1 [L,QSA]

哪个将search.php重写为Search /并将分页重写为Search / 12/1，这是我想要的。

问题是执行搜索时未使用$ _POST ['Search']变量。 没有适当的重定向，它可以正常工作。 任何帮助欢迎

这是用于分页和搜索请求的脚本：

$maxRows_RS_Search = 7;
$pageNum_RS_Search = 0;
if (isset($_GET['pageNum_RS_Search'])) {
  $pageNum_RS_Search = $_GET['pageNum_RS_Search'];
}
$startRow_RS_Search = $pageNum_RS_Search * $maxRows_RS_Search;


$colname_RS_Search = "-1";
if (isset($_SESSION['Search'])) {
  $colname_RS_Search = $_SESSION['Search'];
}
mysql_select_db($database_dconn, $dconn);
$query_RS_Search = sprintf("SELECT * FROM products WHERE (Category LIKE %s OR products.Manufacturer LIKE  %s OR products.Model LIKE  %s OR products.Color LIKE  %s) AND Category!= 'Stage Pianos' AND Category!= 'Recent Pianos' AND Category!= 'Recent Keyboards' AND hidden ='no'", GetSQLValueString("%" . $colname_RS_Search . "%", "text"),GetSQLValueString("%" . $colname_RS_Search . "%", "text"),GetSQLValueString("%" . $colname_RS_Search . "%", "text"),GetSQLValueString("%" . $colname_RS_Search . "%", "text"));


$query_limit_RS_Search = sprintf("%s LIMIT %d, %d", $query_RS_Search, $startRow_RS_Search, $maxRows_RS_Search);
$RS_Search = mysql_query($query_limit_RS_Search, $dconn) or die(mysql_error());
$row_RS_Search = mysql_fetch_assoc($RS_Search);

if (isset($_GET['totalRows_RS_Search'])) {
  $totalRows_RS_Search = $_GET['totalRows_RS_Search'];
} else {
  $all_RS_Search = mysql_query($query_RS_Search);
  $totalRows_RS_Search = mysql_num_rows($all_RS_Search);
}
$totalPages_RS_Search = ceil($totalRows_RS_Search/$maxRows_RS_Search)-1;

$queryString_RS_Search = "";
if (!empty($_SERVER['QUERY_STRING'])) {
  $params = explode("&", $_SERVER['QUERY_STRING']);
  $newParams = array();
  foreach ($params as $param) {
    if (stristr($param, "pageNum_RS_Search") == false && 
        stristr($param, "totalRows_RS_Search") == false) {
      array_push($newParams, $param);
    }
  }
  if (count($newParams) != 0) {
    $queryString_RS_Search = "&" . htmlentities(implode("&", $newParams));
  }
}
$queryString_RS_Search = sprintf("&totalRows_RS_Search=%d%s", $totalRows_RS_Search, $queryString_RS_Search);

分页触发如下：

<td><?php if ($pageNum_RS_Search > 0) { // Show if not first page ?>
             <a href="<?php printf("%s?pageNum_RS_Search=%d%s", $currentPage, 0, $queryString_RS_Search); ?>">First</a>
             <?php } // Show if not first page ?></td>
         <td><?php if ($pageNum_RS_Search > 0) { // Show if not first page ?>
             <a href="<?php printf("%s?pageNum_RS_Search=%d%s", $currentPage, max(0, $pageNum_RS_Search - 1), $queryString_RS_Search); ?>">Previous</a>
             <?php } // Show if not first page ?></td>
         <td><?php if ($pageNum_RS_Search < $totalPages_RS_Search) { // Show if not last page ?>
             <a href="<?php printf("%s?pageNum_RS_Search=%d%s", $currentPage, min($totalPages_RS_Search, $pageNum_RS_Search + 1), $queryString_RS_Search); ?>">Next</a>
             <?php } // Show if not last page ?></td>
         <td><?php if ($pageNum_RS_Search < $totalPages_RS_Search) { // Show if not last page ?>
             <a href="<?php printf("%s?pageNum_RS_Search=%d%s", $currentPage, $totalPages_RS_Search, $queryString_RS_Search); ?>">Last</a>
               <?php } // Show if not last page ?></td>

Answer 1

重定向页面时，始终会释放变量$ _POST。

您可以先使您的php工作，然后使用php函数Header（）进行重定向

Answer 2

是的，当您使用规则中的R标志进行重定向或执行PHP重定向时，POST内容的确会丢失。

如果要在POST操作中使用漂亮的URL，最好像这样更改form的action部分：

<form id="searchbox" action="/Search" method="post">
      <input id="search" name="Search" type="text" placeholder="Search Products">

  <input id="submit" type="submit" value="Search" ></form>

您的规则的更正版本是：

RewriteCond %{REQUEST_METHOD} !POST
rewritecond %{THE_REQUEST} \s/+search\.php[\s?] [NC]
rewriterule ^ /Search/? [R=301,L]

rewritecond %{REQUEST_FILENAME} !-d
rewritecond %{REQUEST_FILENAME} !-f
rewriterule ^Search/?$ /search.php [NC,L,QSA]

RewriteCond %{REQUEST_METHOD} !POST
rewritecond %{THE_REQUEST} \s/+search\.php\?pageNum_RS_Search=([^\s&]+)&totalRows_RS_Search=([^\s&]+) [NC]
rewriterule ^ /Search/%2/%1? [R=301,L]

rewritecond %{REQUEST_FILENAME} !-d
rewritecond %{REQUEST_FILENAME} !-f
rewriterule ^Search/([^/]+)/([^/]+)/?$ /search.php?pageNum_RS_Search=$2&totalRows_RS_Search=$1 [L,QSA]

RewriteCond %{REQUEST_METHOD} !POST将跳过POST请求的重定向规则。
