Question

我制作了2个php页面。一页是“doc.php”，另一页是“chkval.php”。我使用了一些javascript代码来生成“doc.php”中的文本字段。通过使用$ POST，我试图在“chkval.php”页面中捕获文本字段值，但文本字段值没有被错误捕获

使用未定义的常量regCardRecp - 假设为'regCardRecp' D：\ wamp \ www \ chkval.php在第3行regCardRecp

以下是我的完整代码。

doc.php

任何帮助将不胜感激..谢谢

Answer 1

您的问题就在这里，您只是在回显中错过 $ 符号（请参阅Recp）;

<?php

    $regCardRecp = $_POST['regCardRecp'];
    echo($regCardRecp);

?>

无法从javascript获取文本字段值
