我一直在嘗試使用簡單的insertform來顯示上傳到數據庫的圖像。我只能將圖像名稱檢索到「數據文件」中,我想知道的是如何輕鬆地將圖像顯示在相同的表單位置而不是圖像名稱?使用php顯示來自MySQL數據庫的圖像
這是我的結果在這一刻,你可以看到,我只增加了圖像的插件之一,我願與改變「footer.jpg名」圖像顯示在這裏。
<html>
<head>
</head>
<body>
<form action="insertform.php" method="post">
Topic: <input type="text" name="topic"><br />
Name: <input type="text" name="name"><br />
Attendance: <input type="text" name="attendance"><br />
Image: <input type="file" name="image"><br />
<input type="submit" name="submit">
</form>
<?php
if (isset($_POST['submit'])){
$con = mysql_connect("localhost","username","password");
if (!$con){
die("Can not connect: " . mysql_error());
}
mysql_select_db("testingisfun",$con);
$sql = "INSERT INTO Lectures (Topic,Name,Attendance,Image) VALUES ('$_POST[topic]', '$_POST[name]', '$_POST[attendance]', '$_POST[image]')";
mysql_query($sql,$con);
mysql_close($con);
}
?>
</body>
</html>
繼承人「數據文件」。
<html>
<head>
</head>
<body>
<?php
$con = mysql_connect("localhost","username","password");
if (!$con){
die("Can not connect: " . mysql_error());
}
mysql_select_db("testingisfun",$con);
$sql = "SELECT * FROM lectures";
$myData = mysql_query($sql,$con);
echo "<table border = 1>
<tr>
<th>Topic</th>
<th>Name</th>
<th>Attendance</th>
<th>Image</th>
</tr>";
while($record = mysql_fetch_array($myData)){
echo "<tr>";
echo "<td>" . $record['Topic'] . "</td>";
echo "<td>" . $record['Name'] . "</td>";
echo "<td>" . $record['Attendance'] . "</td>";
echo "<td>" . $record['Image'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysql_close($con);
?>
</body>
</html>
