Php 如何将搜索结果回显到其他页面

您需要将查询结果存储在数组中。完成后,您可以在php
中使用header
将用户带到新页面。用户进入新页面后,您可以回显
查询结果(现在存储在$\u会话中
):
首先,创建一个数组:
$queryArray = array();
$_SESSION['search_output'] = $queryArray;
header("Location: newpage.php");
foreach($_SESSION['search_output'] as $value){
echo $value;
}
<?php
session_start();
error_reporting(E_ALL);
ini_set('display_errors', '1');
include_once("db_connects.php");
$queryArray = array();
$goodQuery = true;
$search_output = "";
if(isset($_POST['searchquery']) && $_POST['searchquery'] != ""){
$searchquery = preg_replace('#[^a-z 0-9?!]#i', '', $_POST['searchquery']);
$sqlCommand = "(SELECT id, links, page_body, page_title AS title FROM pages WHERE MATCH enter code here(page_title,page_body) AGAINST ('$searchquery'))";
}
$query = mysql_query($sqlCommand) or die(mysql_error());
$count = mysql_num_rows($query);
if($count > 1){
$search_output .= "<hr />$count results for <strong>$searchquery</strong><hr />";
while($row = mysql_fetch_array($query)){
$queryArray[] = $row;
}
}
else {
$goodQuery = false;
$search_output = "<hr />0 results for <strong>$searchquery</strong><hr />";
}
if($goodQuery){
$_SESSION['search_output'] = $queryArray;
header("Location: newpage.php");
exit;
}
else{
echo $search_output;
}
?>
其次,查询数据库并将每一行存储在我们刚刚创建的数组中
while($row = mysql_fetch_array($query)){
$queryArray[] = $row;
} // close while
第三,将数组移动到会话变量:
$queryArray = array();
$_SESSION['search_output'] = $queryArray;
header("Location: newpage.php");
foreach($_SESSION['search_output'] as $value){
echo $value;
}
<?php
session_start();
error_reporting(E_ALL);
ini_set('display_errors', '1');
include_once("db_connects.php");
$queryArray = array();
$goodQuery = true;
$search_output = "";
if(isset($_POST['searchquery']) && $_POST['searchquery'] != ""){
$searchquery = preg_replace('#[^a-z 0-9?!]#i', '', $_POST['searchquery']);
$sqlCommand = "(SELECT id, links, page_body, page_title AS title FROM pages WHERE MATCH enter code here(page_title,page_body) AGAINST ('$searchquery'))";
}
$query = mysql_query($sqlCommand) or die(mysql_error());
$count = mysql_num_rows($query);
if($count > 1){
$search_output .= "<hr />$count results for <strong>$searchquery</strong><hr />";
while($row = mysql_fetch_array($query)){
$queryArray[] = $row;
}
}
else {
$goodQuery = false;
$search_output = "<hr />0 results for <strong>$searchquery</strong><hr />";
}
if($goodQuery){
$_SESSION['search_output'] = $queryArray;
header("Location: newpage.php");
exit;
}
else{
echo $search_output;
}
?>
第四,将用户移动到新页面:
$queryArray = array();
$_SESSION['search_output'] = $queryArray;
header("Location: newpage.php");
foreach($_SESSION['search_output'] as $value){
echo $value;
}
<?php
session_start();
error_reporting(E_ALL);
ini_set('display_errors', '1');
include_once("db_connects.php");
$queryArray = array();
$goodQuery = true;
$search_output = "";
if(isset($_POST['searchquery']) && $_POST['searchquery'] != ""){
$searchquery = preg_replace('#[^a-z 0-9?!]#i', '', $_POST['searchquery']);
$sqlCommand = "(SELECT id, links, page_body, page_title AS title FROM pages WHERE MATCH enter code here(page_title,page_body) AGAINST ('$searchquery'))";
}
$query = mysql_query($sqlCommand) or die(mysql_error());
$count = mysql_num_rows($query);
if($count > 1){
$search_output .= "<hr />$count results for <strong>$searchquery</strong><hr />";
while($row = mysql_fetch_array($query)){
$queryArray[] = $row;
}
}
else {
$goodQuery = false;
$search_output = "<hr />0 results for <strong>$searchquery</strong><hr />";
}
if($goodQuery){
$_SESSION['search_output'] = $queryArray;
header("Location: newpage.php");
exit;
}
else{
echo $search_output;
}
?>
最后,回显您的数据:
$queryArray = array();
$_SESSION['search_output'] = $queryArray;
header("Location: newpage.php");
foreach($_SESSION['search_output'] as $value){
echo $value;
}
<?php
session_start();
error_reporting(E_ALL);
ini_set('display_errors', '1');
include_once("db_connects.php");
$queryArray = array();
$goodQuery = true;
$search_output = "";
if(isset($_POST['searchquery']) && $_POST['searchquery'] != ""){
$searchquery = preg_replace('#[^a-z 0-9?!]#i', '', $_POST['searchquery']);
$sqlCommand = "(SELECT id, links, page_body, page_title AS title FROM pages WHERE MATCH enter code here(page_title,page_body) AGAINST ('$searchquery'))";
}
$query = mysql_query($sqlCommand) or die(mysql_error());
$count = mysql_num_rows($query);
if($count > 1){
$search_output .= "<hr />$count results for <strong>$searchquery</strong><hr />";
while($row = mysql_fetch_array($query)){
$queryArray[] = $row;
}
}
else {
$goodQuery = false;
$search_output = "<hr />0 results for <strong>$searchquery</strong><hr />";
}
if($goodQuery){
$_SESSION['search_output'] = $queryArray;
header("Location: newpage.php");
exit;
}
else{
echo $search_output;
}
?>
编辑:使用完整代码更新:
$queryArray = array();
$_SESSION['search_output'] = $queryArray;
header("Location: newpage.php");
foreach($_SESSION['search_output'] as $value){
echo $value;
}
<?php
session_start();
error_reporting(E_ALL);
ini_set('display_errors', '1');
include_once("db_connects.php");
$queryArray = array();
$goodQuery = true;
$search_output = "";
if(isset($_POST['searchquery']) && $_POST['searchquery'] != ""){
$searchquery = preg_replace('#[^a-z 0-9?!]#i', '', $_POST['searchquery']);
$sqlCommand = "(SELECT id, links, page_body, page_title AS title FROM pages WHERE MATCH enter code here(page_title,page_body) AGAINST ('$searchquery'))";
}
$query = mysql_query($sqlCommand) or die(mysql_error());
$count = mysql_num_rows($query);
if($count > 1){
$search_output .= "<hr />$count results for <strong>$searchquery</strong><hr />";
while($row = mysql_fetch_array($query)){
$queryArray[] = $row;
}
}
else {
$goodQuery = false;
$search_output = "<hr />0 results for <strong>$searchquery</strong><hr />";
}
if($goodQuery){
$_SESSION['search_output'] = $queryArray;
header("Location: newpage.php");
exit;
}
else{
echo $search_output;
}
?>
我不太清楚你的意思。。。我是新来的php。。。我可以删除else语句吗?@arianna让我知道哪个部分让您感到困惑,我会在我醒来时解决它。它正在重定向到“newpage.php”,但其显示注意:未定义变量:\ newpage.php中的会话在第1行警告:为foreach()提供的参数无效在第1行的\newpage.php中,您需要将session\u start
添加到您正在使用的每个页面的顶部session
,您一定对我很生气,我很抱歉。。但其显示注意事项:未定义索引:第5行的\newpage.php中的search\u输出警告:为第5行的\newpage.php中的foreach()提供的参数无效我已更新了代码(参见上文)
