Question

我正在尝试为我的投资组合网站构建CMS。我在后端创建了所有表单。一切正常，除了我无法在Mysqli的我的投资组合数据库中添加一列。我试图在另一个PHP页面中回显表单数据。一切正常。甚至上传的图像也会移动到站点目录。唯一的问题是在数据库表中插入数据。这是我的代码

<?php
session_start();
?>

<?php


if(isset($_POST['submit']))
{


    $title=$_POST['title'];
    $description=$_POST['description'];
    $duration=$_POST['duration'];
    $category=$_POST['category'];

    $nImage=$_FILES['nImage']['name'];
    $file_tmp=$_FILES['nImage']['tmp_name'];
    $filesize=$_FILES['nImage']['size'];
    $file_ext=strtolower(pathinfo($nImage,PATHINFO_EXTENSION));
    $supported=array('jpg','jpeg','png');

    //Rename File
    $rand=sha1(time());
    $newname=$rand.".".$file_ext;
    $portfolio_img_dir="images/portfolio/".$newname;

    //Check If FileSize is more than 2 MB
    if($filesize<2097152)
    {

        //Check if Extension Matches
        if(in_array($file_ext,$supported))
        {
            //Move Uploaded Image
            if(move_uploaded_file($file_tmp,$portfolio_img_dir))
            {
                $qry=mysqli_query($link,"INSERT INTO `p_o_r_t_f_o_l_i_o`(`title`,`description`,`duration`,`category`,`image`) values('$title','$description','$duration','$category','$portfolio_img_dir')");

                    if($qry)
                    {

                        $_SESSION['add_port_msg_success']="Portfolio Item Successfully Added";
                        header('location:add_portfolio.php');

                    }

                    else
                    {
                        $_SESSION['add_portfolio_msg']="Portfolio Item Failed to Add";
                        header('location:add_portfolio.php');
                    }

            }
            else
            {
                $_SESSION['add_port_msg']="File Failed to Move";
                header('location:add_portfolio.php');
            }
        }

        else
        {
            $_SESSION['add_port_msg']="File Extension not Supported";
            header('location:add_portfolio.php');
        }

    }

    else
    {
        $_SESSION['add_port_msg']="Filesize too Large";
        header('location:add_portfolio.php');
    }

}

else
{
    $_SESSION['add_port_msg']="Invalid Attempt to Access Page";
    header('location:add_portfolio.php');
}
?>

这是我的HTML表格

这是我的数据库表图像：

The first two are added by me from the Insert tab in Database menu 任何帮助将受到高度赞赏。在此先感谢： - ）

Answer 1

要从HTML form提交数据，您使用button，显然不会发送form数据，您必须使用input type="submit"，因此请更改此行代码

<button id="submit" name="submit" class="btn btn-success">Add New Portfolio Item</button>

到

<input type="submit" id="submit" name="submit" class="btn btn-success" value="Add New Portfolio Item" />

Answer 2

你可能应该使用更少的嵌套ifs，特别是当它们都执行＆＃39; else＆＃39;的相同结果时。

if ( ( $a=3 )
  && ( $b=7 )
  && ($car >= 9)
  && ( $name == 'steve' )
  && ( $more == 'stuff' ) ) {
  // Run stuff here
) else {
  exit('error');
}

在mysqli_query();插入后，使用mysqli_error($link);运行错误检查它会告诉您任何问题。 mysqli_query不会返回任何错误，只有＆＃39; true＆＃39;或者＆＃39; false＆＃39;取决于它的运行方式。

Answer 3

我的问题解决了。我在查询中使用了连接。以下是我的工作代码的样子（只是查询）：

$qry=mysqli_query($link,"INSERT INTO `p_o_r_t_f_o_l_i_o`(`title`,`description`,`duration`,`category`,`image`) values('".$title."','".$description."','".$duration."','".$category."','".$portfolio_img_dir."')");

非常感谢所有试图提供帮助的人。干杯!!
