我有一个表单，其中包含来自数据库的自动完成，然后当用户提交时，它将结果发送到 pdf 并将其发送到电子邮件.. 但是当我测试它的一行时它成功但是当添加更多行时，pdf 给我这个词“数组”是代码。
index.php
<?php require("login3.php"); ?>
<?php
if (!empty($_POST)) {
// Used for later to determine result
$success = $error = false;
// Object syntax looks better and is easier to use than arrays to me
$post = new stdClass;
// Usually there would be much more validation and filtering, but this
// will work for now.
foreach ($_POST as $key => $val)
$post->$key = trim(strip_tags($_POST[$key]));
// Check for blank fields
if (empty($post->itemCode) OR empty($post->itemDesc) OR empty($post->itemQty) OR empty($post->itemPrice) OR empty($post->itemAgent))
$error = true;
else {
// Get this directory, to include other files from
$dir = dirname(__FILE__);
// Get the contents of the pdf into a variable for later
ob_start();
require_once($dir.'/pdf.php');
$pdf_html = ob_get_contents();
ob_end_clean();
// Load the dompdf files
require_once($dir.'/dompdf/dompdf_config.inc.php');
$dompdf = new DOMPDF(); // Create new instance of dompdf
$dompdf->load_html($pdf_html); // Load the html
$dompdf->render(); // Parse the html, convert to PDF
$pdf_content = $dompdf->output(); // Put contents of pdf into variable for later
// Get the contents of the HTML email into a variable for later
ob_start();
require_once($dir.'/html.php');
$html_message = ob_get_contents();
ob_end_clean();
// Load the SwiftMailer files
require_once($dir.'/swift/swift_required.php');
$mailer = new Swift_Mailer(new Swift_MailTransport()); // Create new instance of SwiftMailer
$message = Swift_Message::newInstance()
->setSubject('New Order') // Message subject
->setTo(array('hussammoz@aol.com', 'hussammoz@gmail.com' => 'Orange Pharmacy Store')) // Array of people to send to
->setFrom(array('no-reply@net.tutsplus.com' => 'Orange Pharmacy Order System')) // From:
->setBody($html_message, 'text/html') // Attach that HTML message from earlier
- >attach(Swift_Attachment::newInstance($pdf_content, 'nettuts.pdf', 'application/pdf')); // Attach the generated PDF from earlier
// Send the email, and show user message
if ($mailer->send($message))
$success = true;
else
$error = true;

添加新行的js代码：
$(document).ready(function(){
// Use the .autocomplete() method to compile the list based on input from user
$('#itemDesc').autocomplete({
source: 'data/item-data.php',
minLength: 1,
select: function(event, ui) {
var $itemrow = $(this).closest('tr');
// Populate the input fields from the returned values
$itemrow.find('#itemCode').val(ui.item.itemCode);
$itemrow.find('#itemDesc').val(ui.item.itemDesc);
$itemrow.find('#itemPrice').val(ui.item.itemPrice);
$itemrow.find('#itemAgent').val(ui.item.itemAgent);
// Give focus to the next input field to recieve input from user
$('#itemQty').focus();
return false;
}
// Format the list menu output of the autocomplete
}).data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" )
.data( "item.autocomplete", item )
.append( "<a>" + item.itemDesc + "</a>" )
.appendTo( ul );
};
// Get the table object to use for adding a row at the end of the table
var $itemsTable = $('#itemsTable');
// Create an Array to for the table row. ** Just to make things a bit easier to read.
var rowTemp = [

].join('');
// Add row to list and allow user to use autocomplete to find items.

};
// Add row after the first row in table

} // End if last itemCode input is empty
return false;
});
$('#itemDesc').focus(function(){
window.onbeforeunload = function(){ return "You haven't saved your Order. Are you sure you want to leave this page without saving first?"; };
});
}); // End DOM
// Remove row when clicked

问题出在
<td><?php echo $post->itemCode; ?></td>
<td><?php echo $post->itemDesc; ?></td>
<td><?php echo $post->itemQty; ?></td>
<td><?php echo $post->itemPrice; ?></td>
<td><?php echo $post->itemAgent; ?></td>
传递一行时，它读取数据，但传递多行时，它返回名称“数组”！
我尝试这样做，但它给了我：为 foreach() 提供的参数无效
<td><?php foreach ($post->itemCode as $code) {
echo $code;
}
?>
</td>
<td><?php foreach ($post->itemDesc as $desc) {
echo $desc;
}
?></td>
<td><?php foreach ($post->itemQty as $qty) {
echo $qty;
}
?></td>
<td><?php foreach ($post->itemPrice as $price) {
echo $price;
}
?></td>
<td><?php foreach ($post->itemAgent as $agent) {
echo $agent;
}
?></td>
