我有一个数据表，将它的行传递给模态。是否可以使用相同的模态脚本将其直接传递到 php 页面？
这是我的main_page.php
<table id="example1" class="table table-bordered">
<thead>
<th>Reference No</th>
<th>Finger Scan No</th>
<th>Date From</th>
<th>Date To </th>
<th>Tools </th>
</thead>
<tbody>
<?php
$user = $user['fingerscanno'];
$sql = "
SELECT
payroll.payrollno AS payrollno,
payroll.referenceno AS referenceno,
payroll.fingerscanno AS fingerscanno,
payroll.datefrom AS datefrom,
payroll.dateto AS dateto,
USERINFO.USERID,
USERINFO.BADGENUMBER
FROM
payroll,
USERINFO
WHERE
USERINFO.BADGENUMBER = payroll.fingerscanno AND
payroll.fingerscanno='$user'
";
$query = sqlsrv_query($conn, $sql, array(), array("Scrollable" => SQLSRV_CURSOR_KEYSET));
while($row = sqlsrv_fetch_array($query, SQLSRV_FETCH_ASSOC)){
echo "
<tr>
<td>".$row['referenceno']."</td>
<td>".$row['fingerscanno']."</td>
<td>".$row['datefrom']."</td>
<td>".$row['dateto']."</td>
<td>
<button class='btn btn-success btn-sm edit btn-flat' data-id='".$row['referenceno']."'><i class='fa fa-edit'></i> Proof of Attendance</button>
<button class='btn btn-danger btn-sm delete btn-flat' data-id='".$row['referenceno']."'><i class='fa fa-edit'></i> Payslip Summary</button>
</td>
</tr>
";
}
?>
</tbody>
</table>
<?php include 'includes/mymodal.php'; ?>
这是模态函数
$(function(){
$("body").on('click', '.edit', function (e){
e.preventDefault();
$('#edit').modal('show');
var id = $(this).data('id');
getRow(id);
});
这是模态页面
mymodal.php
<div class="modal fade" id="edit">
<input type="hidden" class="decid" id="id" name="id">
<table id="example2" class="table table-bordered">
<thead>
<th>Schedule Date</th>
<th>Schedule Name</th>
<th>Recorded In</th>
<th>Recorded Out</th>
<th>Day Count</th>
<th>Day Value</th>
<th>N.D. Value</th>
<th>Leave Count</th>
<th>R.H. Count</th>
<th>R.H. Value</th>
</thead>
<tbody>
<?php
$sql = "SELECT fingerscanno, scheduledate, schedulename, recordin, recordout, noofdays, rate, nightdifferential, leaveday, regularholiday, specialholiday, referenceno
FROM payrollrecords WHERE fingerscanno='$user' and referenceno='$id'";
$query = sqlsrv_query($conn, $sql, array(), array("Scrollable" => SQLSRV_CURSOR_KEYSET));
while($row = sqlsrv_fetch_array($query, SQLSRV_FETCH_ASSOC)){
echo "
<tr>
<td>".$row['scheduledate']."</td>
<td>".$row['schedulename']."</td>
<td>".$row['recordin']."</td>
<td>".$row['recordout']."</td>
<td>".$row['noofdays']."</td>
<td>".$row['rate']."</td>
<td>".$row['nightdifferential']."</td>
<td>".$row['leaveday']."</td>
<td>".$row['regularholiday']."</td>
<td>".$row['specialholiday']."</td>
</tr>
";
}
?>
</tbody>
</table>
</div>
我的问题是，如何将其传递到表中？这样变量 referenceno='$id' 将从主页接收值。
最佳答案
您需要使用 AJAX。
Ajax 是一种 javascript 方法，允许您与后端 PHP 文件交换信息，就像您尝试做的那样。
AJAX 代码块将数据发送到 mymodal.php 文件，mymodal.php 文件将执行 MySQL 查找并创建 HTML，然后 echo 一个字符串变量(可以是一个 json 对象，也可以是您在 while 循环中构建的 HTML) 返回到主页。 AJAX 代码块将接收从 .done() 函数内的 PHP 文件回显的数据，而且在该函数中，您还可以将 DOM 修改为注入(inject)新数据。对用户来说，看起来他们点击了一个类为 edit 的元素，数据刚刚出现在模态中。
请注意，您没有在 main_file.php 页面中包含 mymodal.php 文件，因为 AJAX 代码块知道如何与该文件通信。
您需要将模式的 HTML 结构添加到主页底部(请注意，它最初设置为 display:none):
<style>
#lamodal{display:none;position:fixed;width:100vw;height:100vh;background:black;opacity:0.8;}
#mdl_inner{width:60%;height:40%;}
.myflex{display:flex;align-items:center;justify-content:center;}
</style>
<div id="lamodal" class="myflex">
<div id="mdl_inner"></div>
</div><!-- #lamodal -->
您的 javascript (AJAX) 看起来像这样:
$(function(){
$("body").on('click', '.edit', function (e){
e.preventDefault();
var id = $(this).data('id');
$.ajax({
type: 'post',
url: 'mymodal.php',
data: 'userid=id'
}).done(function(d){
//console.log('d: '+d);
$('#mdl_inner').html(d);
$('#lamodal').show();
});
});
});
您的 mymodal.php 文件将更改为如下所示:
<?php
$sql = "SELECT fingerscanno, scheduledate, schedulename, recordin, recordout, noofdays, rate, nightdifferential, leaveday, regularholiday, specialholiday, referenceno
FROM payrollrecords WHERE fingerscanno='$user' and referenceno='$id'";
$query = sqlsrv_query($conn, $sql, array(), array("Scrollable" => SQLSRV_CURSOR_KEYSET));
$out = '
<table id="example2" class="table table-bordered">
<thead>
<th>Schedule Date</th>
<th>Schedule Name</th>
<th>Recorded In</th>
<th>Recorded Out</th>
<th>Day Count</th>
<th>Day Value</th>
<th>N.D. Value</th>
<th>Leave Count</th>
<th>R.H. Count</th>
<th>R.H. Value</th>
</thead>
<tbody>
';
while($row = sqlsrv_fetch_array($query, SQLSRV_FETCH_ASSOC)){
$out .= '
<tr>
<td>".$row['scheduledate']."</td>
<td>".$row['schedulename']."</td>
<td>".$row['recordin']."</td>
<td>".$row['recordout']."</td>
<td>".$row['noofdays']."</td>
<td>".$row['rate']."</td>
<td>".$row['nightdifferential']."</td>
<td>".$row['leaveday']."</td>
<td>".$row['regularholiday']."</td>
<td>".$row['specialholiday']."</td>
</tr>
';
}
$out .= '
</tbody>
</table>
';
echo $out;
?>
请注意我们是如何构建一个字符串变量并通过连接构建它的。完成后，只需 echo $out，新构建的 HTML 就会出现在 AJAX 代码块的 .done() 函数中。
