我不明白为什么动态下拉列表不会从我的数据库中填充。:
<!doctype html>
<html>
<body>
<h2>Insert Album</h2>
<form action="insertalbum.php" method="POST">
Title: <input type="text" name="atitle" maxlength='50' required><br>
Band: <select name='bands'>
<?php
$conn = mysqli_connect("Server","database","password","username"); //i put in these placeholder for my actual credentials
// Check connection
if(mysqli_connect_errno()){
echo nl2br("Failed to connect to MySQL: " . mysqli_connect_error() . "\n ");
}
$query = "SELECT DISTINCT name FROM band";
$result = mysqli_query($conn, $query);
while ($row = mysqli_fetch_assoc($result)) {
unset($name);
$name = $row['name'];
echo '<option value="name"> $name </option>';
}
?>
</select>
<br>
Published Year: <input type="number" name="pyear" min='1900' max='2020' required><br>
Publisher: <input type="text" name="pname" maxlength='50' required><br>
Format:<select> <option value="record"> Record </option>
<option value="cd"> CD </option>
<option value="casette"> Casette </option>
</select> <br>
Price: <input type="number" name="price" min='0' max='9999.99'><br>
<input type="submit" value="Insert">
</form>
</body>
</html>
最佳答案
这是一个例子:
<select id="employee">
<option value="" selected="selected">Select Employee Name</option>
<?php
/* connection */
$conn = mysqli_connect("Server","database","password","username");
/* query */
$sql = "SELECT id, employee_name, employee_salary, employee_age FROM employee LIMIT 10";
/* get data from db */
$resultset = mysqli_query($conn, $sql) or die("database error:". mysqli_error($conn));
/* build your dropdown*/
while( $rows = mysqli_fetch_assoc($resultset) ) {
?>
<option value="<?php echo $rows["id"]; ?>"><?php echo $rows["employee_name"]; ?></option>
<?php } ?>
</select>
关于php - 网页的动态下拉列表未从我的数据库中填充，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/49907809/
