问题描述

每当用户选择的图片,然后单击按钮,将图像移动到特定的文件夹,并保存链接到数据库user_image列我想要做的就是。

我的问题是图像的不保存在数据库中列后,我点击提交按钮的实际名称。例如 OPPA /上传/ 这就是保存在数据库中的值没有图片的文件名。

我认为该文件的价值didnt通过photo.php收到谁能帮助我解决这个问题。

 <输入类型=文件ID =imageInputNAME =imageInput接受=图像/ */>
<按钮ID =changePictureNAME =changePicture>提交< /按钮>
 

脚本:

  VAR数据= {};
        。data.imageInput = $('#imageInput)VAL();
        。data.email = $('#邮件)VAL();

        $阿贾克斯({
            键入:POST,
            网址:哥/查看/ photo.php
            数据:数据,
            缓存:假的,
            成功:函数(响应){

            如果(数(响应)== 1)
                {
                   $(#对话 - 确认 -  changedImage)对话框(开放)。
                }
            }
        });
            返回false;
 

photo.php

 < PHP
include_once('../ DBC / database.php中');

$ DB =新的连接();
$ DB = $ DB->数据库连接();
$ DB->的setAttribute(PDO :: ATTR_ERRMODE,PDO :: ERRMODE_EXCEPTION);


$电子邮件=使用isset($ _ POST [电子邮件])? $ _ POST [电子邮件]:;

$图像=和addslashes(的file_get_contents($ _ FILES ['imageInput'] ['tmp_name的值']));
$ IMAGE_NAME =和addslashes($ _ FILES ['imageInput'] ['名称']);
$ IMAGE_SIZE =和getimagesize($ _ FILES ['imageInput'] ['tmp_name的值']);

move_uploaded_file($ _ FILES [imageInput] [tmp_name的值],哥/上传/$ _FILES [imageInput] [名称]);
$位置=OPPA /上传/。 $ _FILES [imageInput] [名称];


如果(!空($ _ POST [电子邮件])){

        $ Q =UPDATE tbl_user SET user_image ='$位置'WHERE USER_EMAIL =:电子邮件;
        $查询= $ DB-> prepare($ Q);
        $查询 - > bindParam(':电子邮件,$电子邮件);
        $结果= $查询 - >执行();
        回声1;
}

?>
 

解决方案

看看这个 HTTP: //malsup.com/jquery/form/#ajaxSubmit

包括插件 jquery.form.js ,然后尝试这个。

  $('#FormID)ajaxSubmit会({// FormID  -  ID形式。
        键入:POST,
        网址:哥/查看/ photo.php
        数据:$('#FormID')序列化()。
        缓存:假的,
        成功:函数(响应){

        如果(数(响应)== 1)
            {
               $(#对话 - 确认 -  changedImage)对话框(开放)。
            }
        }
    });
 

这应该工作。我使用它为Ajax图片上传。

感谢。

What I want to do is whenever a user selects a picture and click the button it will move the image to a specific folder and save the link to the database user_image column.

My problem is the actual name of the picture is not save in the database column after i click the submit button. example Oppa/upload/ thats the value saved in the database no picture file name.

I think the value of the file didnt receive by photo.php can anyone help me solve it.

<input type='file' id="imageInput" name="imageInput" accept="image/*" />
<button  id="changePicture" name="changePicture">Submit</button>

script:

var data = {};
        data.imageInput = $('#imageInput').val();
        data.email = $('#email').val();

        $.ajax({
            type: "POST",
            url: "Oppa/view/photo.php",
            data: data,
            cache: false,
            success: function (response) {

            if (Number(response) == 1)
                {
                   $("#dialog-confirm-changedImage").dialog("open");
                }
            }
        });
            return false;

photo.php

<?php
include_once('../dbc/database.php');

$db = new Connection();
$db = $db->dbConnect();
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);


$email = isset($_POST['email']) ? $_POST['email'] : "";

$image = addslashes(file_get_contents($_FILES['imageInput']['tmp_name']));
$image_name = addslashes($_FILES['imageInput']['name']);
$image_size = getimagesize($_FILES['imageInput']['tmp_name']);

move_uploaded_file($_FILES["imageInput"]["tmp_name"], "Oppa/upload/" . $_FILES["imageInput"]["name"]);
$location = "Oppa/upload/" . $_FILES["imageInput"]["name"];


if(!empty($_POST['email'])) {

        $q = "UPDATE tbl_user SET user_image = '$location' WHERE user_email= :email ";
        $query = $db->prepare($q);
        $query->bindParam(':email', $email);
        $results = $query->execute();
        echo "1";
}

?>

解决方案

Take a look at this http://malsup.com/jquery/form/#ajaxSubmit.

Include that plugin jquery.form.js and then try this.

$('#FormID').ajaxSubmit({ //FormID - id of the form.
        type: "POST",
        url: "Oppa/view/photo.php",
        data: $('#FormID').serialize(),
        cache: false,
        success: function (response) {

        if (Number(response) == 1)
            {
               $("#dialog-confirm-changedImage").dialog("open");
            }
        }
    });

This should work. I'm using it for ajax image upload.

Thanks.
