当心,我是一个编码 n00b 并且刚刚得到一个基本的 PHP 任务。当我尝试打开它时,我不断收到此错误消息
Warning: mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given in /home/jpl8ce/public_html/php_grocery1.php on line 20
这是我正在做的事情的 .php 和 .html 文件。基本上,它是一个杂货数据库,我试图在其中打印商店营业时间、地址和商店名称,其中包含用户在表单中输入的商品。
<html>
<head>
<title>Grocery Results!</title>
</head>
<body>
<h1>
<?php
$connect = mysqli_connect("localhost","jpl8ce","jpl8ce@siedb","grocery");
$item_name = $_post["input1"];
$query_String = " SELECT Stores.Name, Price, Address, Open_Time, Close_Time
FROM (Stores JOIN Carry ON Stores.Store_ID = Carry.Store_ID) JOIN Items ON Carry.Product_ID = Items.Product_ID
WHERE Items.name = $item_name
ORDER BY Close_Time DESC";
$result = mysqli_query($connect, $query_String);
while ($row = mysqli_fetch_assoc($result))
{
echo '<P>'.$row["Stores.Name"].', '.'</P>';
//echo '$' number_format($row["Price"],2).', ';
echo '<P>'.$row["Address"] .', '.'</P>';
echo '<P>'.$row["Open_Time"] .', '.'</P>';
echo '<P>'.$row["Close_Time"].'</P>';
}
mysqli_close($connect);
?>
</h1>
</body>
</html>
这是我的 HTML 代码
<html>
<head>
<title>Grocery Database Search</title>
</head>
<body>
<H1> Grocery Database Search! </H1>
<IMG SRC='grocery_cart_2.jpg'/>
<P> Use this Search Engine to input a name of an item.
After clicking the Search button, the price of the item, as well as the address and hours of the store
the item is located at will be displayed. </P>
<form action="php_grocery1.php" method="POST">
<p>Item: <input type="text" name="input1"/></p>
<p><input type="submit" value="Search!"/></p>
</form>
</body>
</html>
再次感谢各位!
