单击特定搜索结果上的链接（$ sendmessage）后，不会显示发送消息（$ table）的表单。单击链接后，我被提示输入一个空表（不在while循环中的表），但$ _GET函数正在运行。谁能告诉我如何解决这个问题？非常感谢

Answer 1

点击链接后不会设置

$ submit。所以之后的任何代码：

if(isset($submit)) {

不会开枪。

你对这张表格有很多错误。首先，您忘记了<tr>标记后的<td>和<table>。

echo "<center><form name = 'searching' method='POST' action='cpanel.php?manage=".$useraccounts."&rcad=".$viewcustomer."'><table border = 1><tr><td colspan='10'>";
    echo "<select name = 'filter'>";
    echo "<option value ='username'>Username</option>";
    echo "<option value ='username'>Username</option>";
    echo "</select>";
    echo "  <input name='search' type='text' >   "; 
    echo "<input type='submit' name='submit' value='Search'> ";
    echo "<input type='submit' name='back' value='Back'><br><br>";
    echo "</td></tr>";

或者，您可以将<table>标记下方的开头<select>标记移动。

修复之后，尝试将插入值的逻辑移动到循环外的mailtbl_admin中。我猜你只是想要将消息发送给一个用户，所以只有把它移出循环才有意义。

在搜索表单中链接（在搜索查询的while循环上）
