这是我的代码,它将从数据库中获取数据,然后将其存储在 .pdf 文件的表中:

<?php

// test the table functions
error_reporting(E_ALL);
include('includes/pdf/class.ezpdf.php');
//echo 'AAA-1-';
$pdf = new Cezpdf();
//$pdf->selectFont('./fonts/Helvetica');

//connect to db
session_start();
require_once('connect/ticketivity_connect.php');
//echo 'AAA-2-';


//get customer details
$sql_cust = "SELECT * FROM customers where customer_id = '".$_GET['customerid']."'";
$res_cust = mysql_query($sql_cust);
$num_cust = mysql_num_rows($res_cust);
$row_cust = mysql_fetch_assoc($res_cust);

//display customer details
$db_data[] = array('first' => 'Customer Name:', 'second' => $row_cust['cust_name']);
$db_data[] = array('first' => 'Phone Number:', 'second' => $row_cust['cust_phone']);
$db_data[] = array('first' => 'Address:', 'second' => $row_cust['cust_address']);
$db_data[] = array('first' => '>Customer Ref/ Room Number:', 'second' => $row_cust['cust_ref']);
//echo 'AAA-3-';
//get order
$sql_orderinfo= "SELECT * FROM orders where customer_id = '".$_GET['customerid']."'";
$res_orderinfo = mysql_query($sql_orderinfo);
$num_orderid = mysql_num_rows($res_orderinfo);
$row_orderid = mysql_fetch_assoc($res_orderinfo);
//echo 'AAA-4-';
//display order id
$orderid_len = strlen($row_orderid['order_id']);
if($orderid_len == 1) {
//echo 'AAA1--';
$db_data[] = array('first' => 'Order ID:', 'second' => '00000'.$row_orderid['order_id']);
} else if ($orderid_len == 2){
//echo 'AAA2--';
$db_data[] = array('first' => 'Order ID:', 'second' => '0000'.$row_orderid['order_id']);
} else if ($orderid_len == 3){
//echo 'AAA3--';
$db_data[] = array('first' => 'Order ID:', 'second' => '000'.$row_orderid['order_id']);
} else if ($orderid_len == 4){
//echo 'AAA4--';
$db_data[] = array('first' => 'Order ID:', 'second' => '00'.$row_orderid['order_id']);
} else if ($orderid_len == 5){
//echo 'AAA5--';
$db_data[] = array('first' => 'Order ID:', 'second' => '0'.$row_orderid['order_id']);
} else if ($orderid_len == 6){
//echo 'AAA6--';
$db_data[] = array('first' => 'Order ID:', 'second' => $row_orderid['order_id']);
}

//table columns
$col_names = array(
'first' => 'first',
'second' => 'second',
);
//echo 'AAA-5-';
$table_title = 'Customer Details';
//echo 'AAA-6-';
$pdf->ezTable($db_data, $col_names, $table_title, array('width'=>550));
if (isset($d) && $d){
//echo 'AAA-if';
$pdfcode = $pdf->output(1);
$pdfcode = str_replace("\n","\n<br>", $pdfcode);
echo '<html><body>';
echo trim($pdfcode);
echo '</body></html>';
} else {
//echo 'AAA-else';
$pdf->ezStream();
}

?>

输出:

我需要做什么/添加什么?

最佳答案

这个问题不是很清楚,但我假设您正在编写一个 Web 应用程序,并且您正在尝试将 PDF 文档提供给客户端。

首先,您需要设置一个标题,让客户端知道它应该期待 PDF 数据:

header('Content-type: application/pdf');

这将导致大多数浏览器在浏览器窗口中呈现 PDF。如果您希望浏览器提供 PDF 作为下载,请在上述之外执行此操作:
header('Content-Disposition: attachment; filename="filename.pdf"');

您可以设置任何您喜欢的文件名来代替 filename.pdf .

调用这些电话至 header() 很重要。在写入任何输出之前。

顺便说一句,我猜 $d是一个调试标志,但我认为在设置它时执行您正在执行的那些字符串操作不是一个好主意。您最终可能会损坏 PDF 数据。
