[英]Data is not coming from mysql
它表明已創建連接。 但是我不知道查詢中出了什么問題。 查詢之后,我嘗試回顯某些內容,並且該內容在瀏覽器中可見。
<html>
<head>
</head>
<body>
<?php
$servername = "localhost:8888";
$username = "root";
$password = "";
$dbname = "employees";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}else {
echo "Connected successfully";
}
$res = mysqli_query($conn,"select * from dept_manager");
echo"dept_manager";
while($row=mysqli_fetch_assoc($res))
{
?>
<table>
<tr>
<td><?php echo $row['emp_no'] ?></td>
<td><?php echo $row['dept_no']?></td>
<td><?php echo $row['from_date'] ?></td>
<td><?php echo $row['to_date'] ?></td>
</tr>
</table>
<?php
}
?>
</body>
</html>
$sql = "select * from dept_manager";
$result = $conn->query($sql);
while($row = $result->fetch_assoc()){
// your code here
}
試試這個..
在while循環的地方嘗試一下:
<?php
$res = mysqli_query($conn,"select * from dept_manager");
echo"dept_manager";
echo "<table>";
while($row=mysqli_fetch_assoc($res))
{
echo "<tr><td>" . $row['emp_no'] . "</td><td>" . $row['dept_no'] . "</td><td>" . $row['from_date'] . "</td><td>" . $row['to_date'] . "</td></tr>";
}
echo "</table>";
?>
您已經提到servername:localhost:8888,只需檢查一次,刪除8888並嘗試。
我已經在本地系統中嘗試使用您的代碼,相同的代碼可以正常工作。
只要我輸入了我的數據庫名稱和表名稱,它就可以正常工作。
因此,您只需按照我的示例進行一次測試即可。
碼:-
<html>
<head>
</head>
<body>
<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "mydashboard";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
else{
echo "Connected successfully";
}
$res = mysqli_query($conn,"select * from content_values");
while($row=mysqli_fetch_assoc($res))
{
?>
<table>
<tr>
<td><?php echo $row['name'] ?></td>
</tr>
</table>
<?php
}
?>
</body>
</html>
輸出:-
