想要创建一个简单的表单来将值和图像发送到数据库，下面是 php 代码 -

创建了两个php文件process_upload和connection

processs_upload.php

<?php

require 'connection.php';
$conn    = Connect();

$name=$conn->real_escape_string($_POST['name']);
$mobile_number=$conn->real_escape_string($_POST['mobile_number']);
$email_id=$conn->real_escape_string($_POST['email_id']);
$type=$conn->real_escape_string($_POST['type']);

$query   = "INSERT into tb_cform (name,mobile_number,email_id,type) VALUES('" . $name . "','" . $mobile_number . "','" . $email_id . "','" . $type . "')";

if ( 0 < $_FILES['image_file']['error'] ) {
    echo 'Error: ' . $_FILES['image_file']['error'] . '<br>';
}
else{
    $time=time();
     if(($type=='image/png') || ($type=='image/gif') || ($type=='image/jpeg') || ($type=='image/pjpeg') || ($type=='image/jpg')){ //if file is image

 if(move_uploaded_file($_FILES['image_file']['tmp_name'], 'pictures/'.$time.'_'.$_FILES['image_file']['name'])){
    echo 'done ';
 }else{
    echo 'image error';

 }    


 }else{//if file is video

 if(move_uploaded_file($_FILES['image_file']['tmp_name'], 'videos/'.$time.'_'.$_FILES['image_file']['name'])){
    echo 'done';
 }else{
    echo 'video error';

 } 

 } 


 }
$conn->close();
?>

连接.php

<?php


function Connect()
{
 $dbhost = "localhost";
 $dbuser = "user";
 $dbpass = "";
 $dbname = "database";

 // Create connection
 $conn = new mysqli($dbhost, $dbuser, $dbpass, $dbname) or die($conn->connect_error);

 return $conn;
}

?>

在 phpmyadmin 中创建了一个表，下面是该表 -

SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO";
SET time_zone = "+00:00";


CREATE TABLE IF NOT EXISTS `tb_cform` (
  `ID` int(11) NOT NULL AUTO_INCREMENT,
  `name` text CHARACTER SET utf8 NOT NULL,
  `mobile_number` int(11) NOT NULL,
  `email_id` text NOT NULL,
  `type` longblob NOT NULL,
  PRIMARY KEY (`ID`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

HTML 表单

现在，当我运行代码时，我收到图像错误和视频错误消息，连接已成功完成，但收到消息。

最佳答案

尝试授予权限，如下所示

假设您的代码位于/var/www/my_project

尝试 chmod -R 664/var/www/my_project。
