PHP $ _POST不从表单发送数据

时间：2014-03-10 11:17:12

标签： php forms post

我正在尝试将数据从表单发送到我的数据库，但我似乎无法出于某种原因这样做。我已经尝试了很多东西，我知道所有的故障排除，但我想这是超出我的数据库知识范围的东西 - 只有一两个月。这些是我试图在两者之间发送数据的两个文件，但无济于事。有人可以解释一下发生了什么吗？！非常感谢！

所有输入元素都应该在你的表单标签中，使用这个html 

<html>
<head>
<title>Maintenance : Reps</title>
<style type="text/css">
.style1 {
    margin-top: 114px;
}
.style2 {
    border-width: 0px;
}
.style3 {
    color: #000080;
    font-size: 26pt;
    font-family: Calibri;
}
.auto-style1 {
    text-align: right;
}
.auto-style2 {
    text-align: center;
}
.auto-style3 {
    border: 1px solid #000000;

答案 1 :(得分：0)

问题是，您的input个字段位于form开始和结束标记之外。您的表单操作也需要指向repsAdd.php 

<form action="repsAdd.php" method="post" enctype="multipart/form-data">
    <!-- All form elements in here -->
</form>

答案 2 :(得分：0)

您的表单输入不在标签内。

基本上你执行一个只有按钮而没有输入的表单

你也可能希望逃避获取php的数据。

答案 3 :(得分：0)

HTML（XML）是一种层次结构，因此您必须将所有相关的<input>元素放在<form>标记中。

问候

答案 4 :(得分：0)

您需要在所有查询中进行以下更改

`REP_NUM` = '$repnum' etc
