Question

有人可以帮帮我???

我已成功将图片路径和文字存储到MySQL，并将图像存储在文件夹中。

这是我用来上传图片路径和文字的php代码。

 <?php
        if( $_SERVER['REQUEST_METHOD']=='POST' ){
            if( !empty( $_POST['listItems'] ) ){
                $listItems = json_decode( $_POST['listItems'], true ); 
                $mysqli = new mysqli("127.0.0.1:3307", "root", "", "androiddb");
                if( $mysqli->connect_errno ) echo "Failed to connect to MySQL";
                $sql="INSERT INTO `staff_benefit` 
                     ( `type`, `amount`, `description`, `image`, `ts_id` ) 
                      VALUES ( ?, ?, ?, ?, ? )";
                if($stmt=$mysqli->prepare($sql )){
                    $url="http://192.168.1.7:80/Android/CRUD/PhotoUpload/";
                    foreach( $listItems as $item ){ 
                        $id = uniqid();
                        $image_name = $id.".png";
                        $save_path = 'PhotoUpload/'.$image_name;
                        $image_url = $url.$image_name;
                        $bytes=file_put_contents($save_path, base64_decode($item['image']));
                        if( !$bytes ){
                            echo 'Error saving image';  
                        }else{
                            $stmt->bind_param('sssss', 
                            $item['type'], 
                            $item['amount'], 
                            $item['description'], 
                            $image_url, 
                            $item['ts_id'] );
                            if( !$res=$stmt->execute()){ 
                                echo 'Query failed with code: '.$stmt->errno;
                            }
                        }
                    } 
                }
                $mysqli->close();
            }
        }
    ?>

但是当我尝试更新android中的行时，该行没有改变，但它在php中显示updated successfully。

这是我的更新php

<?php 
    if($_SERVER['REQUEST_METHOD']=='POST'){
        //Getting values 

        $id = $_POST['id'];
        $type = $_POST['type'];
        $amount = $_POST['amount'];
        $description = $_POST['description'];

        //importing database connection script 
        require_once('dbConnect.php');

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

            $id = uniqid();
            $url="http://192.168.107.115:80/Android/CRUD/PhotoUpload/";
            $image_name = $id.".png";
            $save_path = 'PhotoUpload/'.$image_name;
            $image_url = $url.$image_name;
            $bytes =file_put_contents($save_path, base64_decode($_POST['image']));

            $sql = "UPDATE staff_benefit SET type = '$type', amount = '$amount', description='$description', image='$image_url' 
            WHERE id = '$id'";
        }
        else{

             $sql = "UPDATE staff_benefit SET type = '$type', amount = '$amount', description='$description' WHERE id = '$id'";

        }

        //Updating database table 
        if(mysqli_query($con,$sql)){
            echo ' Updated Successfully';
        }else{

            echo mysqli_error($con);
            exit;
        }

        //closing connection 
        mysqli_close($con);
    }
?>

更新代码

        }

        updateImageAndText ue = new updateImageAndText();
        ue.execute();
    }

我有两个功能，一个是更新，另一个是 updateWithoutImage 。他们使用相同的PHP。但php适用于 updateWithoutImage ，但不适用于更新功能。

Answer 1

好的，我知道为什么update（）不起作用。

在我的PHP代码中，我有两个$id。将$id内的if(isset($_POST['image']))更改为$id1，现在可以更新。

行无法更新
