Question

我正在为网站使用PHP，AngularJS和HTML。该网站将从数据库请求数据并将其显示在网站上。

我想要做的是如果我在PHP文件中说3个函数并且我在页面上有3个控制器我希望每个控制器能够在PHP文件中请求特定函数并返回结果查询。

以下是我的代码。我测试了查询，我知道它们正在工作。

HTML / AnguarJS

            <div class="row">

PHP文件

<?php
getPlayerStats();
getAssists();
function getPlayerStats()
{
    include_once("connect.php");

    $connect = connect();
    $seasonID = 21;

    $i = 1;
    $y = 0;
    $result = $connect->query("SELECT TP.TeamPlayerID, TP.Sweater, TP.Position, P.FirstName, P.LastName, 0 + TP.Sweater as SweaterNo

    $output = "";

    while($rs = $result->fetch_assoc())
    {
        if ($output != "") {$output .= ",";}

我希望Assists控制器能够显示PHP文件中的getAssists函数和Leaders控制器的结果，以显示getPlayerStats函数的结果。

我缺少什么让这项工作？

Answer 1

首先，删除网址中的括号;它应该是action=getPlayerStats而不是action=getPlayerStats()

现在，不要在PHP文件中调用这两个函数：

// Incorrect way
getPlayerStats();
getAssists();

相反，找出所要求的行动：

// Correct way
$supported_actions = array('getPlayerStats', 'getAssists');
$action = isset($_GET['action']) ? $_GET['action'] : false;
if (!in_array($action, $supported_actions)) {
    // No valid action found, you might want to send a 404 status here, or something like that
}
$action(); // Execute the action!
