Question

我尝试制作一个包含图片上传的表单。假设我有一个表participant，我想插入其中：

INSERT INTO `participant`(`Matric`, `Name`, `IC`, `Address`, `Tel`, `Phone`, 
`Email`, `Phone_Ref`, `Institute`, `Course`, `Pic_Participant`, `Exp_Work`) 
VALUES ([value-1],[value-2],[value-3],[value-4],[value-5],[value-6],[value-7],
[value-8],[value-9],[value-10],[value-11],[value-12])

我想要做的是插入数据并上传图片。其属性为Pic_Participant。

我使用ajax Ajax Image Upload and Resize with jQuery and PHP搜索上传内容。然后我认为流程，填写表格然后在同一页面上传图像，然后上传图像后将图像数据发送到db，但表单尚未提交。如何从表格图像中获取属性以添加到表格参与者中？

请帮帮我。我是新来的。

我尝试这段代码但得到一个错误：未定义的变量

 <?php

session_start();

include 'dbconnect.php';

function is_valid_type($file)
{
$valid_types = array("image/jpg", "image/jpeg", "image/bmp", "image/gif");

if (in_array($file['type'], $valid_types))
return 1;
return 0;
}


function showContents($array)
{
echo "<pre>";
print_r($array);
echo "</pre>";
}


$TARGET_PATH = "upload/";

Answer 1

如果我弄错了你想要的是将图像插入（可能是MYSQL）数据库。

您可以使用base64_encode()图像二进制数据并在数据库中插入生成的明文来实现此目的。

$image = 'path/to/image/image.png';
$imagefordbs  =  base64_encode($image);
/*now your image is ready to be stored in database*/

但是，这种方法有缺点，因为base64_encode（）比原始内存多占33％，处理输入二进制文件需要一些时间，并且mysql中有这种要求的专用数据类型 - BLOB。< / p>

在我阅读您的问题时，您希望使用您找到的教程/代码上传图片，然后在图片上传后单独提交表单。

要知道文件上传后您可以在哪里找到图像，您有两种选择：

让图片上传在上传完成时返回文件路径，并在表单中包含该变量（例如隐藏输入）;
将图像路径存储在会话变量中，以便在提交数据字段时，可以访问该变量以获取图像的信息。

编辑：您需要查看表单插件的文档以获取更多详细信息，但您可以从上传的php脚本中返回一些内容。您可以使用echo文件名，然后在success函数中使用它：

    function afterSuccess(return_value)  {
        console.log(return_value);  // here you have what was echoed out by php

        $('#UploadForm').resetForm();  // reset form
        $('#SubmitButton').removeAttr('disabled'); //enable submit button
    }

php - 表单包括图片上传
