大家好，几天来我一直在 table 上敲头试图解决这个问题，我完全被难住了。
索引.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<div id="page_container">
<div class="form_container">
<h3>Add and Delete rows dynamically with textboxes using jQuery:</h3>
<form action="addemp.php" method="post">
<table id="expense_table" cellspacing="0" cellpadding="0">
<thead>
<tr>

<tbody>
<tr>

<td><input type="text" name="Address1_01" /></td>

</tr>
</tbody>
</table>
<INPUT type="submit">
</form>
<input type="button" value="Add Row" id="add_ExpenseRow" />
</div> <!-- END form_container -->
<div class="clearfix"></div>
</div>
</body>
</html>
自定义.js
$(function(){
// GET ID OF last row and increment it by one
var $lastChar =1, $newRow;
$get_lastID = function(){
var $id = $('#expense_table tr:last-child td:first-child input').attr("name");
$lastChar = parseInt($id.substr($id.length - 2), 10);
//console.log('GET id: ' + $lastChar + ' | $id :'+$id);
$lastChar = $lastChar + 1;
$newRow = "<tr> \
<td><input type='text' name='CompanyName_0"+$lastChar+"' /></td> \
<td><input type='text' name='Employee_0"+$lastChar+"' /></td> \
<td><input type='text' name='Phonenum_0"+$lastChar+"' /></td> \

<td><input type='text' name='Zip_0"+$lastChar+"' /></td> \
<td><input type='button' value='Delete' class='del_ExpenseRow' /></td> \
</tr>"
return $newRow;
}
// ***** -- START ADDING NEW ROWS
$('#add_ExpenseRow').live("click", function(){
if($('#expense_table tr').size() <= 9){
$get_lastID();
$('#expense_table tbody').append($newRow);
}else{
alert("Reached Maximum Rows!");
};
});
$(".del_ExpenseRow").live("click", function(){
$(this).closest('tr').remove();
$lastChar = $lastChar-2;
});
});
addemp.php 这是我完全迷失的地方
for ($j = 0; $j < count($_POST['CompanyName_01']); $j++) {
$CompanyName = $_POST['CompanyName_01'][$j];
$Employee = $_POST['Employee_01'][$j];
$Phonenum = $_POST['Phonenum_01'][$j];
$Address1 = $_POST['Address1_01'][$j];
$Address2 = $_POST['Address2_01'][$j];
$City = $_POST['City_01'][$j];
$State = $_POST['State_01'][$j];
$Zip = $_POST['Zip_01'][$j];
$con=mysqli_connect("localhost","USER","password","DATABASE");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="INSERT INTO EmployeeInfo (CompanyName, Employee, Phonenum, Address1, Address2, City, State, Zip)
VALUES('$CompanyName','$Employee','$Phonenum','$Address1','$Address2','$City','$State','$Zip')";
if (!mysqli_query($con,$sql))
{
die('Error: ' . mysqli_error($con));
}
echo "1 record added";
}//end of the for loop
我需要帮助构建 php 代码以输入数据库。 我尝试了许多不同的方法来读取和写入数据，但卡住了。
我尝试更改动态创建的文本字段和数组，但是我无法更改 custom.js 代码以使其立即工作。
代码运行时我的思考过程:
index.php 创建 CompanyName_01 、 Employee_01 。等等
然后，当您从 custom.js 中点击“添加”时，会创建附加的
公司名称_02、员工_02。等等
公司名称_03、员工_03。等等
所以我认为在我的 addemp.php 中我可以用 while 循环构建一个数组
<br>
$companyname_array CompanyName_0[i]<br>
$employee_array Employee_0[i]<br>
等等
然后使用创建的变量添加到我的数据库
但是我无法获得任何我正在尝试工作的代码。
我哪里出错了。
任何帮助都会很棒。
最佳答案
你的 for 循环语法有点不对:)
<?php
for ($j = 1; $j < count($_POST['CompanyName_0']); $j++) {
$CompanyName = $_POST['CompanyName_0$j'];
$Employee = $_POST['Employee_0$j'];
$Phonenum = $_POST['Phonenum_0$j'];
$Address1 = $_POST['Address1_0$j'];
$Address2 = $_POST['Address2_0$j'];
$City = $_POST['City_0$j'];
$State = $_POST['State_0$j'];
$Zip = $_POST['Zip_0$j'];
}
?>
或者
<?php
for ($j = 1; $j < count($_POST['CompanyName_0']); $j++) {
$CompanyName = $_POST['CompanyName_0'.$j];
$Employee = $_POST['Employee_0'.$j];
$Phonenum = $_POST['Phonenum_0'.$j];
$Address1 = $_POST['Address1_0'.$j];
$Address2 = $_POST['Address2_0'.$j];
$City = $_POST['City_0'.$j];
$State = $_POST['State_0'.$j];
$Zip = $_POST['Zip_0'.$j];
}
?>
每次循环运行时，再检查一下与mysql的连接，将其放在循环之前。我强烈建议使用 stmt->execute();用于循环条目
