Question

我想允许用户插入文本并将其添加到图像然后下载图像本地一切都很完美，但是当我将代码上传到服务器时，它并不起作用任何想法??

<html>
<body>
    <form method="POST" action="process.php"> 
        <input type="text" name="username"/>
        <br>  <br>
        <input type="text" name="username2"/>
        <br>  <br>
        <input type="submit" name="subpic" />
    </form>
<?php

if (isset($_GET['name'])&&isset($_GET['x'])) {
   $file = " ".$_GET['name']."".$_GET['x'].".jpg";
echo "<a href='process2.php?name=".$file."'>download</a> "; 
}
?>
</body>
</html>

流程代码

<?php
$rImg = ImageCreateFromJPEG("doctor.jpg"); 
$cor = imagecolorallocate($rImg, 255, 0, 0);
$user = $_POST['username']; 
$user2 = $_POST['username2'];  
$font = 'roboto.ttf';
imagettftext($rImg, 39.5, 0, 155, 719, $cor, $font, $user);
imagettftext($rImg, 39.5, 0, 155, 780, $cor, $font, $user2);
header('Content-type: image/jpeg');
imagejpeg($rImg, " ".$user."".urldecode($_GET['x']).".jpg");
header('location:main.php?name='.$user.'&x='.$_GET['x'].'');   
?>

和process2代码是：

<?php
$name= $_GET['name'];

    header('Content-Description: File Transfer');
    header('Content-Type: application/force-download');
    header("Content-Disposition: attachment; filename=\"" . basename($name) . "\";");
    header('Content-Transfer-Encoding: image/jpeg');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($name));
    ob_clean();
    flush();
    readfile($name); //showing the path to the server where the file is to be download
    exit;
?>
