Question

如果我在PHP文件中创建insert_teacher('bla bla','bla bla','dqsd')，但是当我想用HTML表单创建它时，它不显示任何内容，并且我的数据库中没有插入任何内容。

<?php
  include_once("resources/functions.php");
echo 1;
  if(isset($_POST['submit']))
  {
      $name=$_POST['name'];
      $exp=$_POST['exp'];
      $sub=$_POST['sub'];

         $insert=insert_teacher($name,$exp,'dqsd');// return 1 or 0
          echo $insert;



  }

Answer 1

这里有很多错误，但无论如何我都会尝试帮助。

首先，您的提交应该有一个名称。例如

# Get data
import urllib.request as request
request.urlretrieve('http://seanlahman.com/files/database/baseballdatabank-master_2016-03-02.zip', "baseballdatabank-master_2016-03-02.zip")
from zipfile import ZipFile
zip = ZipFile('baseballdatabank-master_2016-03-02.zip')
zip.extractall()

import pandas as pd
import matplotlib.pyplot as plt
%matplotlib inline

batting_df = pd.read_csv("baseballdatabank-master\core\Batting.csv")
batting_df = batting_df[batting_df['AB'] > 20]
batting_df['batting_average'] = batting_df['H'] / batting_df['AB']

# Plot distribution
batting_averages = batting_df['batting_average'].dropna()
batting_averages.plot.kde()

# Plot confidence interval
import scipy.stats
import numpy as np, scipy.stats as st
stderr = st.sem(batting_averages)
interval1 = (batting_averages.mean() - stderr * 1.96, batting_averages.mean() + stderr * 1.96)
plt.plot(interval1[0], 12)
plt.show()

其次，使用提交按钮的名称调用填充的表单。例如

<input type="submit" name="insertx"/>

第三，阅读如何在if(isset($_POST['insertx'])){ //your code }或PDO中插入php，除非你想被黑客攻击！（NB：mysqli）

有很多东西需要学习，但它不是很难。一切顺利

Answer 2

您必须为提交标记添加名称：

<input type="submit" name="submit">

HTML表单不适用于PHP代码
