jquery模式对话框不会从2个表

标签: php jquery mysql sql

我在使用bootstrap模式查找(jQuery模式对话框)来检索来自2个表的数据时遇到了困难,

所以,我有两张桌子:

 first is Student Table
Id      studentCode     studentName

1       S01             Michael Jordan

2       S02             Patric Ewing

和另一张表:

Books

id  studentCode  bookCode  bookName

1    S01         B001      PHP

2    S01         B002      SQL

3    S02         B003       C#

4    S02         B004      Java

我有这个代码,可以使用学生和书籍表中的jQuery对话框检索数据:

<div class="row">
        <div class="col-md-5">
            <h2>&nbsp;</h2>
        </div>
    </div>
    <form action="action" onsubmit="dummy();
            return false">
        <div class="form-group">
            <label for="varchar">Student Code</label>
            <div class="row">
                <div class="col-md-4">

                      <input type="text" class="form-control" name="studentcode" id="studentcode" placeholder="Student Code" readonly />

                      <input type="text" class="form-control" name="studentname" id="studentname" placeholder="Name " readonly />

                </div>

                <div class="col-md-2">
                  <button type="button" class="btn btn-default" data-toggle="modal" data-target="#myModal">. . .</button>
                </div>
            </div>
        </div>
<table width="446" border="1">
  <tr>
    <th scope="row">Student Code</th>
    <td><strong>Product Code</strong></td>
    <td><strong>Product Name</strong></td>
    <td><strong>QTY</strong></td>
  </tr>
  <tr>
    <th scope="row"><label for="studentcode"></label>
      <input type="text" name="student" id="student"></th>
    <td><label for="bookcode"></label>
      <input type="text" name="bookcode" id="bookcode"></td>
    <td><label for="bookname"></label>
      <input type="text" name="bookname" id="bookname"></td>
    <td><label for="qty"></label>
      <input type="text" name="qty" id="qty"></td>
  </tr>
</table>


              <input type="submit" value="Save" class="btn btn-primary" />

        </form>

                <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
            <div class="modal-dialog" style="width:800px">
                <div class="modal-content">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span>  </button>
                        <h4 class="modal-title" id="myModalLabel">Lookup Student</h4>
                    </div>
                    <div class="modal-body">
                        <table id="lookup" class="table table-bordered table-hover table-striped">

                                    <th>Student Code</th>
                                    <th>Student Name</th>
                                </tr>
                            </thead>
                            <tbody>
                                <?php

                                $con = mysqli_connect('localhost', 'root', '', 'obat');
                                $sql = mysqli_query($con,'select * from student p inner join books b on p.studentcode=b.studentcode');
                                while ($r = mysqli_fetch_array($sql)) {
                                    ?>
                                    <tr class="pilih" data="<?php echo $r['studentcode']; ?>", name="<?php echo $r['studentname'] ?>", code="<?php echo $r['bookcode'] ?>", book="<?php echo $r['bookname'] ?>">
                                        <td><?php echo $r['studentcode']; ?></td>
                                        <td><?php echo $r['studentname']; ?></td>
                                    </tr>
                                    <?php
                                }
                                ?>
                            </tbody>
                        </table>  
                    </div>
                </div>
            </div>
        </div>
        <script src="js/jquery-1.11.2.min.js"></script>
        <script src="bootstrap/js/bootstrap.js"></script>
        <script src="datatables/jquery.dataTables.js"></script>
        <script src="datatables/dataTables.bootstrap.js"></script>
        <script type="text/javascript">


            $(document).on('click', '.pilih', function (e) {
                document.getElementById("studentcode").value = $(this).attr('data');
                document.getElementById("studentname").value = $(this).attr('name');
                document.getElementById("student").value = $(this).attr('data');
                document.getElementById("bookcode").value = $(this).attr('code');
                document.getElementById("bookname").value = $(this).attr('book');
                $('#myModal').modal('hide');
            });


            $(function () {
                $("#lookup").dataTable();
            });

        </script>

当我点击名称时,它会将数据发送到主表单。代码成功地将数据发送到主表单,但对于books表,它只发送1行数据

  1. 如何根据学生姓名(代码)从书籍表中检索所有数据?

  2. 我想在books表上添加一个文本框以手动填充它并将其保存到另一个表中。我怎么能这样做?

1 个答案:

答案 0 :(得分:0)

基于您的2个SQL表和SQL查询:

select * from student p inner join books b on p.studentcode=b.studentcode;

这只会从student表中提取内容,因为没有b.studentcode个字段符合p.studentcode个值。

B01 != S01
B02 != S02

要解决此问题,您需要确保两列以某种方式对齐。要么改变一个或另一个中的值,要么:

B01 == B01
B02 == B02

或者:

S01 == S01
S02 == S02

这将返回如下记录集:

S01  Michael Jordan  B001  PHP
S01  Michael Jordan  B002  SQL
S02  Patric Ewing    B003  C#
S02  Patric Ewing    B004  Java

这假定了一些事情,比如你的意思是“S”代表学生,003意味着B003。我还建议更具体的SQL查询:

select p.studentCode, p.studentName, b.bookCode, b.bookName from student p inner join books b on p.studentCode=b.studentCode;

在你的jQuery中,我建议使用data属性与你选择的属性相比,以避免混淆并制作更多可移植代码。例如,看这里:

https://jsfiddle.net/Twisty/43fLLc4c/3/

HTML代码段

<tr class="pilih" data-sc="S01" data-sn="Michael Jordan" data-bc="B001" data-bn="PHP">
  <td>S01</td>
  <td>Michael Jordan</td>
</tr>
<tr class="pilih" data-sc="S01" data-sn="Michael Jordan" data-bc="B002" data-bn="SQL">
  <td>S01</td>
  <td>Michael Jordan</td>
</tr>
<tr class="pilih" data-sc="S02" data-sn="Patric Ewing" data-bc="B003" data-bn="C#">
  <td>S02</td>
  <td>Patric Ewing</td>
</tr>
<tr class="pilih" data-sc="S02" data-sn="Patric Ewing" data-sc="B004" data-bn="Java">
  <td>S02</td>
  <td>Patric Ewing</td>
</tr>

<强>的JavaScript

$(function() {
  $(".pilih").on("click", function(e) {
    $("#studentcode").val($(this).data("sc"));
    $("#studentname").val($(this).data("sn"));
    $("#student").val($(this).data("sn"));
    $("#bookcode").val($(this).data("bc"));
    $("#bookname").val($(this).data("bn"));
    $("#myModal").modal("hide");
  });
  $("#lookup").dataTable();
});

希望有所帮助。
