我一直在尝试使用简单的insertform来显示上传到数据库的图像。我只能将图像名称检索到“数据文件”中,我想知道的是如何轻松地将图像显示在相同的表单位置而不是图像名称?使用php显示来自MySQL数据库的图像
这是我的结果在这一刻,你可以看到,我只增加了图像的插件之一,我愿与改变“footer.jpg名”图像显示在这里。
<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>
继承人“数据文件”。
<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>
