我的表单POST不再识别POST输入变量，因此isset始终为false

标签： php html forms

我的表单过去总是有效，但是当我尝试上传多张图片时，它突然无法识别POST输入。

我尝试过几件事情，包括：查看PHP.INI以查看是否有错误，print_r数组以查看其中的内容（它是空的），制作确定输入字段有一个动作和名称，并删除不相关的javascript，但似乎没有任何效果。我确定我忽略了一些东西，但我已经检查了一切我认为可能是错误的东西。

谢谢我提前！

if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
 if ((isset($_POST['title'])) && (isset($_POST['title_small'])) &&        (isset($_POST['article_small'])) && (isset($_POST['article'])) && (!empty($_POST['title'])) && (!empty($_POST['title_small']))

    include('../includes/database.php');
    $title = $_POST['title'];
    $title_small = $_POST['title_small'];
    $article_small = $_POST['article_small'];
    $article = $_POST['article'];

    if($_FILES['file_array']['error'][0] == 0)
    {

        for($i = 0; $i < count($tmp_name_array); $i++)

            if ($size_array[$i] > 500000) {

                $uploadOk = 0;
            }

            }

            // Check if $uploadOk is set to 0 by an error
            if ($uploadOk == 0) {
                echo "Sorry, your file was not uploaded.";
            // if everything is ok, try to upload file
            } 
            else 
            {
                if(move_uploaded_file($tmp_name_array[$i], "../uploads/".$name_array[$i]))
                {
                    echo $name_array[$i]." upload is complete<br>";
                } 
                else
                {
                    echo "move_uploaded_file function failed for ".$name_array[$i]."<br>";
                }
            }
        }

        $sql = "INSERT INTO articles (title, title_small, article_small, article, image_article) VALUES ('$title', '$title_small', '$article_small', '$article', '$imgnames')";
        if (mysqli_query($conn, $sql)) 
        {
            header('location: ../paper.php');

        mysqli_close($conn);
    }
    else
     {
        array_push($errors, "You forgot something!");
     }
   }
 }

?>

形式：

      <form class="form" id="form1" action="<?php echo $_SERVER['PHP_SELF']; ?>"  method="post" enctype="multipart/form-data">
        <input name="title" type="text" class="feedback-input" placeholder="Title" maxlength="100"/>
        <input name="title_small" type="text" class="feedback-input" placeholder="Small Title" maxlength="100"/>
        <textarea name="article_small" class="feedback-input" id="comment" placeholder="Small Article"></textarea>
        <textarea name="article" class="feedback-input" id="comment" placeholder="Article"></textarea>
        <input type="file" name="file_array[]" accept="image/*" id="imguploadsmall" />
       <input type="submit" value="ADD" id="button-blue" name="submit" />
    </form>
   </div>

只有错误是：

答案 0 :(得分：0)

看起来它对php.ini中的文件相关设置有一些限制。尝试上传非常小的文件并检查。 php错误日志提供了详细的错误信息。
