嵌套报价问题 - $ _SERVER ['PHP_SELF']无效

Question

echo "<form method='post' style='display:inline' enctype='multipart/form-data' action='<?php echo $_SERVER[\'PHP_SELF\'];?>'> <input type='submit' name='delete' class='button' value='Delete'></form>";

出于某种原因，无论我尝试使用嵌套引号进行什么组合，我都无法使上述方法正常工作。

有什么想法吗？真的，非常感谢。我到处寻找。

Answer 1

echo "<form method='post' style='display:inline' enctype='multipart/form-data' action='".$_SERVER['PHP_SELF']."'> <input type='submit' name='delete' class='button' value='Delete'></form>";

您正试图在php echo

中再次打开php标签

Answer 2

你的代码中有双重回声，所以试试吧..注意：在使用它之前关闭php代码。

<form method='post' style='display:inline' enctype='multipart/form-data' action='<?php echo $_SERVER['PHP_SELF'];?>'> <input type='submit' name='delete' class='button' value='Delete'></form>";
