Question

当页面操作时，我不希望这段代码运行。

    //There was an identical id and request is somewhat real. (Still possible of a lucky guess)
    if($array['isbeingwritten'] == 1)
    {
        //The article is already being written.
        echo '<script type="text/javascript">alert("That article is being written. Someone beat you to it. You will now be redirected.");</script>';
        echo '<script type="text/javascript">window.location.href="write.php";</script>';
    }

所以我做到了这一点：

if(!isset($_POST['submit']))
{
  //There was an identical id and request is somewhat real. (Still possible of a lucky guess)
  if($array['isbeingwritten'] == 1)
  {
        //The article is already being written.
    echo '<script type="text/javascript">alert("That article is being written. Someone beat you to it. You will now be redirected.");</script>';
    echo '<script type="text/javascript">window.location.href="write.php";</script>';
  }
}

这不起作用。按下提交后它仍然运行该代码!!这是我的表格：

            <form method="post" id="writearticle" action=""> 
                <textarea rows="30" cols="85" id="articlecontent" name="content" placeholder="Write the article here. Try to abide by the instructions and keywords provided." onkeyup="checkWordCount();" ></textarea>
                <br />      
                <input type="submit" id="submit" name="submitarticle" value="Submit Article" class="submit" disabled />     

                <br /><br /><br /><br /><br />
            </form>

Answer 1

更改代码if(!isset($_POST['submit'])) to if(!isset($_POST['submitarticle']))

为什么这段代码仍在运行，即使我允许这样做
