重定向与表单变量不能正常工作 [英] Redirect with form variable doesn't work properly
本文介绍了重定向与表单变量不能正常工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我对文件（search.php中），使用接收到一个变量，如下所示：
在session_start（）;
如果（使用isset（$ _ POST ['搜索']））{
$ _SESSION [搜索] = $ _ POST ['搜索'];
}
形式：
＆LT;形式ID =搜索框行动=/ search.php中的方法=邮报＆GT;
＆LT;输入ID =搜索NAME =搜索类型=文本占位符=搜索产品＆GT;
＆LT;输入ID =提交类型=提交值=搜索＆GT;＆LT; /形式GT;
所以它提交给自己
我有以下的重定向到位：
的RewriteCond％{THE_REQUEST} \ S / +搜索\的.php？ [NC]
重写规则^ /搜索/？ [R = 301，L]
的RewriteCond％{} REQUEST_FILENAME！-d
的RewriteCond％{} REQUEST_FILENAME！-f
重写规则^搜索/？$ /search.php？ [L，QSA]
的RewriteCond％{THE_REQUEST} \ S / +搜索\ .PHP \ pageNum_RS_Search =（[^ \ S＆安培] +）？＆安培; totalRows_RS_Search =（[^ \ S＆功放;] +）[NC]
重写规则^ /搜索/ 2％/ 1％？ [R = 301，L]
的RewriteCond％{} REQUEST_FILENAME！-d
的RewriteCond％{} REQUEST_FILENAME！-f
重写规则^搜索/（[^ /] +）/（[^ /] +）/ $ /search.php?pageNum_RS_Search=$2&totalRows_RS_Search=$1 [L，QSA]
这重写它的search.php搜索/和寻呼搜索/ 12/1，它就是我想要做的事。
在执行搜索的$ _ POST [搜索]变量不被使用的问题。没有适当的重定向它工作正常。 任何帮助欢迎
这是剧本的分页和搜索请求：
$ maxRows_RS_Search = 7;
$ pageNum_RS_Search = 0;
如果（使用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;
如果（使用isset（$ _ SESSION ['搜索']））{
$ colname_RS_Search = $ _SESSION [搜索];
}
mysql_select_db（$ database_dconn，$ dconn）;
$ query_RS_Search =的sprintf（SELECT * FROM产品WHERE（类别LIKE％s或products.Manufacturer如％s或products.Model如％s或products.Color如％S）和分类！='舞台钢琴和类别！= 最近的钢琴和类别！='最近的键盘和隐藏='不'，GetSQLValueString（％。$ colname_RS_Search。％，文），GetSQLValueString（％。$ colname_RS_Search。％ ，文），GetSQLValueString（％$ colname_RS_Search％，文），GetSQLValueString（％$ colname_RS_Search％，文））。。。。;
$ query_limit_RS_Search =的sprintf（％S LIMIT％D，％D，$ query_RS_Search，$ startRow_RS_Search，$ maxRows_RS_Search）;
$ RS_Search =请求mysql_query（$ query_limit_RS_Search，$ dconn）或死亡（mysql_error（））;
$ row_RS_Search = mysql_fetch_assoc（$ RS_Search）;
如果（使用isset（$ _ GET ['totalRows_RS_Search']））{
$ totalRows_RS_Search = $ _GET ['totalRows_RS_Search'];
} 其他 {
$ all_RS_Search =请求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 =;
如果（！空（$ _ SERVER ['QUERY_STRING']））{
$ PARAMS =爆炸（＆放大器;，$ _ SERVER ['QUERY_STRING']）;
$ newParams =阵列（）;
的foreach（$ PARAMS为$参数）{
如果（stristr（$参数，pageNum_RS_Search）==假放;＆安培;
stristr（$参数，totalRows_RS_Search）== FALSE）{
array_push（$ newParams，$参数）;
}
}
如果（计数（$ newParams）！= 0）{
$ queryString_RS_Search =与＆amp; 。ヶ辆（破灭（与＆amp;，$ newParams））;
}
}
$ queryString_RS_Search = sprintf的（＆放大器; totalRows_RS_Search =％D％S，$ totalRows_RS_Search，$ queryString_RS_Search）;
呼叫触发如下：
＆LT; TD＆GT;＆LT;如果PHP（$ pageNum_RS_Search＆GT; 0）{//如果不是第一页＆GT显示;
＆所述; A HREF =＆其中; PHP的的printf（％S pageNum_RS_Search =％D％的，$当前第0，$ queryString_RS_Search？;＆GT;？）＆gt;首先＆所述; / a取代;
＆LT; PHP} //显示如果不是第一页＆GT;＆LT; / TD＆GT;
＆LT; TD＆GT;＆LT;如果PHP？（$ pageNum_RS_Search＆GT; 0）{//如果不是第一页＆GT显示;
＆LT; A HREF =＆LT; PHP的printf？（％S pageNum_RS_Search =％D％S，$当前页，MAX（0，$ pageNum_RS_Search - 1），$ queryString_RS_Search？;＆GT;）＆GT; previous＆所述; / a取代;
＆LT; PHP} //显示如果不是第一页＆GT;＆LT; / TD＆GT;
＆LT; TD＆GT;＆LT; PHP如果（$ pageNum_RS_Search＆LT; $ totalPages_RS_Search）{//显示如果不是最后一页＆GT？;
＆LT; A HREF =＆LT; PHP的printf（％S pageNum_RS_Search =％D％S，$当前页，分（$ totalPages_RS_Search，$ pageNum_RS_Search + 1），$ queryString_RS_Search？;＆GT;）＆gt;接下来＆LT; / A＆GT;
＆LT; PHP} //显示如果不是最后一页＆GT;＆LT; / TD＆GT;
＆LT; TD＆GT;＆LT; PHP如果（$ pageNum_RS_Search＆LT; $ totalPages_RS_Search）{//显示如果不是最后一页＆GT？;
＆LT; A HREF =＆LT; PHP的printf（％S pageNum_RS_Search =％D％S，$当前页，$ totalPages_RS_Search，$ queryString_RS_Search？;＆GT;）＆GT;最后＆LT; / A＆GT;
＆LT; PHP} //显示如果不是最后一页＆GT;＆LT; / TD＆GT;
解决方案
是帖子的内容，当你做使用研究标记从您的规则重定向或做确实丢失从PHP重定向。
如果你想用pretty的URL中POST操作，最好是修改动作你的组成部分是这样的：
＆LT;形式ID =搜索框行动=/搜索的方法=邮报＆GT;
＆LT;输入ID =搜索NAME =搜索类型=文本占位符=搜索产品＆GT;
＆LT;输入ID =提交类型=提交值=搜索＆GT;＆LT; /形式GT;
你的规则还更正的版本是这样的：
的RewriteCond％{REQUEST_METHOD}！POST
的RewriteCond％{THE_REQUEST} \ S / +搜索\ .PHP [\ S？] [NC]
重写规则^ /搜索/？ [R = 301，L]
的RewriteCond％{} REQUEST_FILENAME！-d
的RewriteCond％{} REQUEST_FILENAME！-f
重写规则^搜索/？$ /search.php [NC，L，QSA]
的RewriteCond％{REQUEST_METHOD}！POST
的RewriteCond％{THE_REQUEST} \ S / +搜索\ .PHP \ pageNum_RS_Search =（[^ \ S＆安培] +）？＆安培; totalRows_RS_Search =（[^ \ S＆功放;] +）[NC]
重写规则^ /搜索/ 2％/ 1％？ [R = 301，L]
的RewriteCond％{} REQUEST_FILENAME！-d
的RewriteCond％{} REQUEST_FILENAME！-f
重写规则^搜索/（[^ /] +）/（[^ /] +）/ $ /search.php?pageNum_RS_Search=$2&totalRows_RS_Search=$1 [L，QSA]
的RewriteCond％{REQUEST_METHOD}！POST 将跳过重定向规则 POST 的要求。
I have on file (search.php) that uses a variable that is received as follows:
session_start();
if (isset($_POST['Search'])){
$_SESSION['Search'] = $_POST['Search'];
}
The form:
<form id="searchbox" action="/search.php" method="post">
<input id="search" name="Search" type="text" placeholder="Search Products">
<input id="submit" type="submit" value="Search" ></form>
so it submits to itself
I have the following redirects in place:
rewritecond %{THE_REQUEST} \s/+search\.php? [NC]
rewriterule ^ /Search/? [R=301,L]
rewritecond %{REQUEST_FILENAME} !-d
rewritecond %{REQUEST_FILENAME} !-f
rewriterule ^Search/?$ /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]
Which rewrites it search.php to Search/ and the paging to Search/12/1 Which is what I want it to do.
The problem is when a search is executed the $_POST['Search'] variable is not being used. Without the redirects in place it works fine. Any help welcome
This is the script for the paging and Search request:
$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, $queryString_RS_Search);
paging is triggered as follows:
<td><?php if ($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, $queryString_RS_Search); ?>">Last</a>
<?php } // Show if not last page ?></td>
解决方案
Yes POST content indeed gets lost when you do a redirect using R flag from your rules OR do a redirect from PHP.
If you want to use pretty URL in POST operation it is better to change the action part of your form like this:
<form id="searchbox" action="/Search" method="post">
<input id="search" name="Search" type="text" placeholder="Search Products">
<input id="submit" type="submit" value="Search" ></form>
Also corrected version of your rules would be this:
RewriteCond %{REQUEST_METHOD} !POST
rewritecond %{THE_REQUEST} \s/+search\.php[\s?] [NC]
rewriterule ^ /Search/? [R=301,L]
rewritecond %{REQUEST_FILENAME} !-d
rewritecond %{REQUEST_FILENAME} !-f
rewriterule ^Search/?$ /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 will skip redirect rules for POST requests.
