我叫 Luis，我正在尝试用 html、css 和 php 制作一个文件，从数据库中获取信息并将其输出。但它必须与 html 位于同一页面中，以便我可以使用 CSS 进行编辑...谢谢大家!
<html>
<head>
</head>
<body>
<script>
</script>
<form action="<?php include 'file.php';?>" method="POST">
<b>Busque Jรก</b>
<input type="text" name="prestador" placeholder="prestador">
<input type="text" name="cidade" placeholder="cidade">
<input type="submit">
</form>
</body>
</html>
PHP 文件:
<?php
$servername = "localhost";
$username = "username";
$password = "";
$dbname = "test";
$namer = $_POST['prestador'];
$cities = $_POST['cidade'];
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT name,address,city FROM tb_prestadores WHERE name = '$namer' AND city = '$cities'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "name: " . $row['name']. " Endereço - : " . $row['address']." Cidade :".$row['city']."<br>";
}
} else {
echo "It is going to else";
}
$conn->close();
?>
最佳答案
您错误地包含/插入了文件。
你应该做什么: 1) 复制您的 html 代码并将其粘贴到您的 php 代码的底部，即在结束 '?>' 标记之后。您的代码应如下所示:
<?php
$servername = "localhost";
$username = "username";
$password = "";
$dbname = "test";
$namer = $_POST['prestador'];
$cities = $_POST['cidade'];
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT name,address,city FROM tb_prestadores WHERE name = '$namer' AND city = '$cities'";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "name: " . $row['name']. " Endereço - : " . $row['address']." Cidade :".$row['city']."<br>";
}
} else {
echo "It is going to else";
}
$conn->close();
?>
<html>
<head>
<!-- include your css here-->
</head>
<body>
<script>
</script>
<form action="" method="POST">
<b>Busque Jรก</b>
<input type="text" name="prestador" placeholder="prestador">
<input type="text" name="cidade" placeholder="cidade">
<input type="submit">
</form>
</body>
</html>
顺便说一句，这不是编写应用程序代码的“最佳”方式。请查看Smarty或其他一些模板语言以及 MVC一旦掌握了 php 和 html 基础知识。祝你好运!
