GET，將不會收到我的POST？ PHP

Question

我爲我的在線遊戲創建了一個動態簽名製造商。

您可以通過手動

http://pernix-rsps.com/sig/pcard.php?user=usernamehere
我試圖讓一個USERBOX並提交創建的簽名，讓人們不必訪問

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

和編輯它，我想它在輸入用戶名時爲他們創建鏈接

我的用戶名框的代碼

<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> 

然後pcard.php

在進入並在框中submiting的用戶名，它只是需要你到pcard.php沒有圖像正在取得

任何想法

Answer 1

您在PHP中使用錯誤的字段名稱。在您的形式使用字段名username：

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

而在你的PHP你試圖讓GET['user']。改變GET['username']，一切都應該工作（獲得價值的部分;））。
