每次单击提交时添加列表项 [英] Add list item every time i click submit
问题描述
我想要一个脚本，每当我单击提交"按钮时，该脚本就会将表单中的文本回显到div标签.
I want a script which will echo a text from a form to a div tag every time i click the submit button.
我很快就可以做到这一点，但是我希望即使我提交另一个文本，文本也仍然可以显示在div中.我希望每个新提交的文本都创建一个列表.将其添加到上一个列表.
i was able to do that in no time but i want the text to still be displayed in the div even when i submit another. i want every new submitted text to create a list. adding it to a previous list.
这可能与数据库有关，但是我想知道，因为每次我单击提交"时，我只会得到当前提交的文本.
may be this got to do with database but i will like to know as every time i click the submit i only get the current text been submitted.
此类脚本的示例
<?php
$text = $_POST['text'];
?>
<html>
<div>
<?php echo "<ul>";
echo "<li>".$text."</li>";
echo "</ul>";
?>
</div>
<form method="POST" action="<?php echo $_SERVER['PHP_SELF'];?>">
Name: <input type="text" name="text" /><br/>
<input type="submit" value="Submit"/>
</form>
</html>
我希望每次单击提交时都将条目添加到<li>列表中.
i want to just be adding entries to the <li> list every time i click submit.
