How to submit a form without opening a new window_html/css_WEB-ITnose

This form has to open a new window in the page to run, and it returns.
Forced single page, but this post is not executed... ugh
So depressing

<form action="" method="POST" target="_blank">  <tr class="firstalt">	<td align="center"><b>xxxxx系统</b></td>  </tr>  <tr class="secondalt">		<td align="left"  ><br><ul><li>您的ip是：127.0.0.1 请注意您的行为,因此带来的风险将由您承担!</li></ul></td>  </tr>  <tr class="firstalt">	<td align="center" height=40  >验证号: <input name="code" value="" type="text"  class="input" size="100" ><input name="" value="提交" type="submit"  class="input" size="30" ><input name=action type=hidden value=code></td>  </tr></table>	</td></tr></form>

This is the form, with the sentence added below 9d35a927475978fa9e8c3cc42f3309dc
Because it needs to be in php
if ($POST['action' ] == "code") Use
like this, so...

But the problem doesn’t seem to be here

You change

<form action="" method="POST" target="_blank">

to

<form action="" method="POST" target="_self">

That’s it, haha, the points are mine

Thank you very much!
