Question

我为我的在线游戏创建了一个动态签名制作者。

您可以通过

手动创建sig

http://pernix-rsps.com/sig/pcard.php?user=usernamehere
我试图创建一个用户框并提交，以便人们不必访问

http://pernix-rsps.com/sig/pcard.php?user=USERNAME

并编辑它，我希望它在输入用户名

时为它们创建链接

我的用户名框代码

    <center>



<form name="sig" id="sig" method="get" action="pcard.php">
<table border="0">
<tr><td colspan="2"><?php echo isset($_GET["user"])?$_GET["user"]:"";?> </td></tr>
<tr><td width="30">Username</td><td width="249"><input name="username" type="text" id="username" width="150px" placeholder="Username" /> </td></tr>

<tr><td></td><td><input name="btnsubmit" type="submit" id="btnsubmit" title="create sig" /></td></tr>
</table>
</form>

            </center>

然后是pcard.php

<?php

    if (isset($_GET['user'])) {
        $image_path = "img/saved_cards/".$_GET['user'].".png";
        if (file_exists($image_path)) {

                pullFromCache($image_path);
                exit;
            }
        }
        generate();
    }

    function pullFromCache($image_path) {
        header("Content-type: image/png");
        $image = imagecreatefrompng($image_path);

在框中输入并提交用户名后，只需将您带到pcard.php而不制作图像

任何想法

Answer 1

您在PHP中使用了错误的fieldname。在表单中，您使用字段名username：

<input name="username" ... />

在PHP中，您尝试获取GET['user']。在GET['username']中进行更改，一切都应该有效（获取值部分;）。

GET，不会收到我的POST？ PHP
