重复 HTML 元素，并将 php 变量传递给 PHP 中的函数
我正在尝试创建一个简单的产品目录网站，我想为每个产品显示卡片。我试图通过 PHP 模板变量显示卡片，并将名称、img src、价格等作为参数传递给打印卡片的函数。
这是我的index.php代码：
<?php
require('./php/product_card.php');
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

当我只是 echo $prod_name; 时 它显示了我传递的产品的名称，但它在 $prod_card 变量中不起作用。看起来是什么问题？如何才能实现这一点呢？

偶然的你
就这样吧。您的变量被视为普通文本字符。您需要将 PHP 变量附加到 HTML 字符串中<?phpfunction product_card($prod_name, $prod_img, $prod_desc, $prod_price, $prod_price_disc) { $prod_card = ' <div class="col-md-3 col-sm-6 my-3 my-md-1"> <form action="index.php" method="get"> <div class="card"> <div> <img src="$prod_img" alt="error" class=" img-fluid card-img-top"> </div> <div class="card-body"> <h5 class="card-title">'. $prod_name.' </h5> <p class="card-text">'. $prod_desc.' </p> <h5><s class="text-secondary">'.$prod_price_disc.'</s><span class="mx-2"></span><span class="price">'.$prod_price.'</span></h5> </div> </div> </form> </div> '; echo $prod_card;}?> -
人到中年有点甜
您必须将字符串与变量连接起来，例如 Echo 'fix string'.$var; 在您的情况下，在每个 var $prod_img, $prod_name 之前以 ' 和 add 结束。在你的情况下 <img src="'.$prod_img.'" 等等 -
不负相思意
<div class="col-md-3 col-sm-6 my-3 my-md-1"> <form action="index.php" method="get"> <div class="card"> <div> <img src="$prod_img" alt="error" class=" img-fluid card-img-top"> </div> <div class="card-body"> <h5 class="card-title">'. $prod_name.' </h5> <p class="card-text">'. $prod_desc.' </p> <h5><s class="text-secondary">$prod_price_disc</s><span class="mx-2"></span><span class="price">$prod_price</span></h5> </div> </div> </form></div>或许？我不确定但是
