我已经阅读了有关此问题的所有帖子,但是,到目前为止,没有一个解决方案对我有用.显然,我忽略了一些重要的事情.我也不知道如何调试会话.我读了一篇文章,PHP会话调试,但它超出了我的头脑.
所以,就像其他问题一样,当我导航到我的应用中的另一个页面时,无论是通过链接还是表单提交,我的会话都会消失.我不知道为什么我的会话消失了.如果有人有时间帮我调查,我们将不胜感激.
这些是我的php.ini设置
; Name of the session (used as cookie name).
session.name = PHPSESSID
; The path for which the cookie is valid.
session.cookie_path = /
这是第一个要显示的视图
<?php
session_start();
if (!isset($_SESSION['session_id'])) {
$_SESSION['session_id'] = session_id();
}
if (!isset($_SESSION['invoices'])) {
$_SESSION['invoices'] = $invoices;
}
if (isset($_SESSION['session_id'])) {
print_r($_SESSION['session_id'] . " in invoiceList.<br />");
} else {
echo 'No session ID set in invoiceList <br />';
}
?>
<div>
<table>
<tr>
<th>Customer Name</th>
<th>Invoice Date</th>
<th>Invoice Number</th>
</tr>
<tr>
<?php
include_once 'form/editInvoice.php';
if (isset($invoices)) {
foreach ($invoices as $invoice) {
?>
<tr>
<td><?php echo $invoice['customer_name'] ?></td>
<td><?php echo $invoice['invoice_date'] ?></td>
<td><?php echo $invoice['invoice_number'] ?></td>
<td><a href='<?php echo $_SERVER['SCRIPT_NAME']; ?>/retrieve?class=InvoiceLineItems&id=<?php echo $invoice['invoice_id']; ?>'><?php echo $invoice['invoice_id']; ?></a></td>
</tr>
<?php
}
} else {
echo 'No invoices retrieved.';
}
?>
</tr>
</table>
</div>
这是包含的表格:
<?php
session_start();
if (isset($_SESSION['session_id'])) {
print_r($_SESSION['session_id'] . "in editForm<br />");
} else {
echo 'No session ID set in editForm <br />';
}
if (!$_POST) {
?>
<form action="<?php $_SERVER['PHP_SELF'] ?>" method="post">
<fieldset>
<legend>Enter Updated PO Number</legend>
<li>PO Number: <input type="text" name="po_number"/></li>
</fieldset>
<input type="submit" value="Submit" />
<input type="button" onclick="alert('Changes Canceled.')" value="Cancel"/>
</form>
<?php }
?>
最后,用户点击主页面中链接的详细信息页面.
<?php
session_start();
if (isset($_SESSION['session_id'])) {
print_r($_SESSION['session_id'] . "<br />");
} else {
echo 'No session ID set invoice<br />';
}
?>

switch ($info['role_indicator']) {

编辑:我删除了会话检查并更新了代码示例.我<head>在index.php中的标签之前添加了session_start().我已经验证我可以写入会话临时文件夹.
当我在我的控制器中执行此代码以使用新的PO编号更新发票时,我达到了模型的功能,但会话已经消失.
//If form is posted, update line items with PO number and date.
if (isset($_POST['po_number'])) {
$this->invoice->update();
}
到达会话变量赋值时,我没有会话数据:
public function update(){
$con = $this->_getLocalConn();
$invoices = $_SESSION['invoices'];
try {
$sqlUpdate = $con->prepare("UPDATE invoices
SET po_number = ?, po_issued_date = ?
WHERE invoice_id = ?");
foreach ($invoices as $record) {
$sqlUpdate->execute(array(
$_POST['po_number'],
getdate(),
$record['invoice_id']
));
}
} catch (PDOException $e) {
print $e->getMessage();
}
//get the PO number being used to update the records
//perform db update where po_number = input
//notify user of success and display updated records.
}
