帶有 PHP 並連接到 MySQL 的購物車

Question

晚上好，我目前正在通過 PHP 和 MySQL 實現購物車，我在第 172 行開始出現以下錯誤，我一直在查看報價，但找不到問題，有什么辦法可以解決這個？

ERROR : Parse error: syntax error, unexpected 'img' (T_STRING), expecting ';' or ',' in B:\XAMPP\htdocs\dashboard\PHP_Assessments\Sport_Cars\cart.php on line 171

我一直在將這個購物車從 mysqli 版本更改為 pdo 並且我在使其工作時遇到了一些麻煩，我希望可以解決這個問題。

謝謝你的幫助。

Answer 1

這是 PHP 語法錯誤。 您可以參考下面的屏幕截圖以獲取一些錯誤作為示例。 您需要先確保沒有錯誤，然后才能使其正常工作

Answer 2

不不不！ 當你使用

echo "<div></div>"; You never Put a  " Inside of two "" You can only use ''

echo "<div class=""></div>";Wrong
echo "<div class=''></div>";Correct

-- 讓我們看看這條線 --

echo "<form method='post' action='cart.php?action=add&id=" .$row['carID']. ' ">";

你做錯了。 首先這是雙引號所以你不需要。 $row['carId'] 。

固定代碼是：

    $id = $row['id'];
    echo "<form method=\"Post\" action=\"car.php?action=add&id=$id\" >";

您需要更改整個代碼:(

Answer 3

你在包含 $result 的 foreach 循環中有一些錯誤，所以試試這個：

foreach($result as $row){ 

    echo "<div class='col-md-4'>";
    echo "<form method='post' action='cart.php?action=add&id=" .$row['carID'].  ">";
    echo "<div><img class='img-responsive' src= " .'view/images/'. $row['Photo'] . " 
    /> 
    <br/> ";  
    echo  "<h4 class='text-info'>" . $row['carName'] . "</h4> ";
    echo "<h4 class='text-danger'>".$row['carPrice'] . "</h4> ";  
    echo "<input type='text' name='quantity' class='form-control' value='1' /> ";  
    echo "<input type='hidden' name='hidden_name' value='" . $row['carPrice'] . "'/> 
    ";  
    echo  "<input type='hidden' name='hidden_price' value='" . $row['carPrice']  . 
    "'/> ";  
    echo  "<input type='submit' name='add_to_cart' style='margin-top:5px;' class='btn 
    btn- 
    success' value='Add to Cart' /> ";
    echo "</div></form></div>";

}

您可以嘗試使用 printf 來幫助提高代碼的可讀性。 http://php.net/printf
