我的bootstrap表单不会将数据发布到phpmyadmin数据库中，我点击提交并且没有提交任何内容，我已经包含了配置文件和我的表单文件。配置文件与注册表单一起使用，因此我认为它与我的表单有关。我的网站是在hostinger上运行的，网址是www.grademanager.16mb.com。当您按提交页面重新加载时，不会弹出任何错误消息。
更新：我已将sql语句更改为pdo语句，但它只会将前两个语句，学生名和第一个主题插入到我的php管理数据库中。它不会插入其他两个语句。
另外，如果数据已成功提交，我如何确保它只返回到thanks.html文件？

答案 0 :(得分：1)
错误1：
您错过了type="submit"
<button id="singlebutton" type="submit" name="submit" class="btn btn-success">Submit</button
错误2：
您正在混合所有mysql，mysqli和PDO扩展。那就是你的原因 无法插入db。
在连接文件中，您使用过PDO。插入时，你写了mysqli，但你的语法似乎是为了mysql。
错误3：
您的插入查询语法不正确。
$sql = "INSERT INTO paststudent (name,subject1,grade,subject2,grade2,subject2,grade2,subject3,grade3,subject4,grade4,attendance,gender) VALUES ('$_POST[name]','$_POST[subject1]','$_POST[grade1]','$_POST[subject2]','$_POST[grade2]','$_POST[subject3]','$_POST[grade3]','$_POST[subject4]','$_POST[grade4]','$_POST[attendance]','$_POST[gender]')";
答案 1 :(得分：0)
不确定这会产生什么影响，但我看到2个关闭表格标签
答案 2 :(得分：0)
- 在参数和值
之前输入空格- 使用mysql_query
<?php
require("includes/config.php");
if(isset($_POST['submit'])) {
$sql = "INSERT INTO paststudent (name, subject1, grade, subject2, grade2, subject2, grade2, subject3, grade3, subject4, grade4, attendance ,gender) VALUES ('$_POST[name]', '$_POST[subject1]', '$_POST[grade1]', '$_POST[subject2]', '$_POST[grade2]', '$_POST[subject3]', '$_POST[grade3]', '$_POST[subject4]', '$_POST[grade4]', '$_POST[attendance]', '$_POST[gender]')";
if (mysql_query($sql)) {
echo "succesfully submitted to the database";
} else {
echo "Well this is embarising";
}
}
?>
