Question

我失去了＆＃34;我从表单提交按钮。表格完美无缺，我不知道自己做了什么，但刚才我看到它已经消失了。我在css中造型，也许是弄得一团糟。我也无法在devTools中找到它。可能这将是一个面对面的问题，对此感到抱歉。这是代码（我只把提交后写的css的一部分放在那里），但我不确定我只用css搞砸了：

＆＃13;

.table_ocjene {
	
	text-align: center;
	 table-layout:fixed;
	 border-collapse: collapse;
    width: 100%;
}

.table_ocjene th {
	word-wrap:break-word;
	
	}
.table_ocjene td {
	width: auto;}
	
   
  input[type=text] {
	background: #f9ffd1;
	width:80%; }

＆＃13;

<?php

session_start();
 

if(!isset($_SESSION['username']) || empty($_SESSION['username'])){
  header("location: login.php");
  exit;
}
 require_once "wp-config.php";

Answer 1

//关闭隐藏的输入

<input type = 'hidden',  name = 'id[]' id = 'id' value = "<?php print $row['id'] ?>" />

Answer 2

您的提交按钮没有消失，它就在您的HTML中。

echo "<input type = 'submit' name = 'submit' value = 'Upload'>";

您的表单是否有效是另一回事。

缺少PHP表单中的提交按钮
