我在通过选项列表中的链接传递会话变量时遇到一个主要问题。 搜索了很多帖子后,我没有看到任何有帮助的内容。 这是代码示例。
enter code here
session_start();
enter code here
foreach($clients 作为 $client){
enter code here
$_SESSION['name']=$client ->user_name;
enter code here
$_SESSION['title']=$client ->user_title;
enter code here
$_SESSION['client_id']=$client ->user_id;
enter code here
$_SESSION['info']=$client ->user_info;
enter code here
$_SESSION['type']=$client ->user_type;
enter code here
$_SESSION['project_ref']=$client ->user_project_ref;
enter code here
$_SESSION['client_project']=$client ->user_project;
enter code here
$client_id=$_SESSION['client_id'];
}
然后在列表中我们有
enter code here
在“客户”页面中我们有
enter code here
session_start();
enter code here
if(isset($_SESSION['name'])) {
enter code here
$_SESSION['client_id'];
enter code here
$_SESSION['名称'] ;
enter code here
$_SESSION['标题'];
enter code here
$_SESSION['信息'];
enter code here
$_SESSION['类型'];
enter code here
$_SESSION['project'];//回显$project;
enter code here
$_SESSION['ref']; }
enter code here
get_results($wpdb->prepare(" SELECT * FROM vo_wp_clients where user_id= '$client_id'"));
页面打开,但结果不正确。 如果我回显会话变量,它会显示错误条目的设置。 我确信我错过了一些简单的东西,但任何帮助都会非常有帮助
听起来您在尝试从列表中选择客户端时遇到了会话变量的一些问题。
在我当前的 PHP 项目中,我面临类似的问题,所以我绝对可以帮助您解决这种情况!
这个东西可以帮助你获得输出。
1。显示客户列表
// When displaying clients
foreach ($clients as $client) {
echo '<a href="client_page.php?client_id=' . $client->user_id . '">' . $client->user_name . '</a>';
}
2。在客户端页面设置会话变量
client_page.php
<?php
session_start();
if (isset($_GET['client_id'])) {
$client_id = intval($_GET['client_id']); // Sanitize input
// Query to get the client info
$clients = $wpdb->get_results($wpdb->prepare("SELECT * FROM vo_wp_clients WHERE user_id = %d", $client_id));
if (!empty($clients)) {
$client = $clients[0]; // Get the first client record
$_SESSION['name'] = $client->user_name;
$_SESSION['title'] = $client->user_title;
$_SESSION['client_id'] = $client->user_id;
$_SESSION['info'] = $client->user_info;
$_SESSION['type'] = $client->user_type;
$_SESSION['project_ref'] = $client->user_project_ref;
$_SESSION['client_project'] = $client->user_project;
}
}
// In this way now you can use the session variables as needed
if (isset($_SESSION['name'])) {
echo $_SESSION['name'];
echo $_SESSION['title'];
echo $_SESSION['info'];
// and so on...
}
?>
