Php FPDF-在一次创建中生成多个pdf

我试图在php表单中单击一次就使用fpdf生成多个集群内pdf报告

测试中心是独立报告的集群。单击submit按钮时，它将调用fpdf的php文件。我的密码还没用

到目前为止，在我的php中：

<?php
$program="select distinct test_center  from sa_sase_result where school_year = '$content' ";
$prog=mysql_query($program);
while($row = mysql_fetch_array($prog))
{
    echo '<option>' .$row['test_center'] . '</option>';      
}  

$message = null;

if($_SERVER["REQUEST_METHOD"] == "POST") { 
    if(!isset($_POST['depchair'])) {

    } else if($_POST['depchair']=="") {

    } else {            
        $input_depchair = addslashes($_POST['depchair']);                       

        $input_depchair = addslashes($_POST['depchair']);
        $pro_email="select control_no  from sa_student_infoe y where y.test_center = '$input_depchair'";
        $pro_address=mysql_query($pro_email);

        $address = mysql_result($pro_address, 0);
    }                   
}
?>

编辑：这里是generate_pdf.php文件

<?php

require('fpdf/fpdf.php');


 mysql_connect("localhost", "root", "1234") or die(mysql_error()); 
 mysql_select_db("final") or die(mysql_error()); 

 $query = "SELECT * FROM sa_student_infoe, sa_student_edubg, sa_sase_result, sa_accounts";
      $result = mysql_query($query) or die(mysql_error());
      while($row = mysql_fetch_array($result, MYSQL_BOTH)){
      $control_no[] = $row['control_no'];
      $surname[] = $row['surname'];
      $fname[] = $row['fname'];

... 有什么问题吗？它不起作用。它不会一次生成多个报告。报告中将包含哪些字段以及输出内容？就因为我不能复制输出，您可以将输出作为屏幕截图公开吗？名称、年龄等字段位于fpdf的单独php文件中。对于html代码，用户可以选择创建报告所需的集群。集群是一组学生。所以用户基本上是在所选集群中创建学生报告。当然，我会上传一个屏幕截图。谢谢你没有放弃我。我不熟悉javascriptjs，你能帮我浏览一下吗？它只是为你准备的模板。我看不出每个文件的生成代码定义在哪里。此php将用于生成不同的文件，这意味着此代码必须读取$_REQUEST['q']，并在sql中为每个案例选择数据。就像：$query=SELECT*fromsa_student_infoe，sa_student_edubg，sa_sase_result，sa_accounts，其中一些字段='$_请求['q']；

$("#id_of_generate_it_button").click(function () {
    var N = 10;// ten pdf files will be generated and stored to the disk
    for (i = 0; i < N; i++) {// 'the loop' -- walk thru all parallel generation processes connected to the event
        parameter = N;// just to definite each single generated file
        $.get("generate.php?q=parameter", function (data) {// start the ajax process to generate single document
                                                           // ?q=parameter i wrote just for passing to the php file some dependent parameter for each single file 
            // pdf #i generated
        });
    }// end for parallel generating N pdf files to the disk
});//end click 

$query = "SELECT * FROM sa_student_infoe, sa_student_edubg, sa_sase_result, sa_accounts WHERE some_field = ' . $_REQUEST['q'] . '";// single record from all
