下面的代码是一个简单的示例，涉及图像或文件上传的所有方面，看一下并理解它

<?php

size you wish and also set "upload_max_filesize = 120M" post_max_size must be greater than upload_max_filesize in oder
to work, also set the "max_input_time" and "max_execution_time" to 300 (5 minutes specified in seconds)
or more if you wish finally set them in your php script as below, also set "memory_limit = 1024M" or what you wish
by default "memory_limit = 128M" Note in Wamp this should be done in C:\wamp64\bin\apache\apache2.4.23\bin\php.ini and 
in C:\wamp64\bin\php\php5.6.25\php.ini or C:\wamp64\bin\php\php7.0.10\php.ini depending on the php version you are using

这是我找到的用于文件上传的快速教程：

http://www.tizag.com /phpT/fileupload.php

我很快就读完了它，但它为您提供了一些安全内容的基本概念

Here is a quick tutorial I found for doing a file upload:

I read through it pretty quick, but it gives you the basic idea with some safety stuff to boot

在这里指定您的目录路径，

$target_path = "uploads/";

用 uploadedfile 替换文件输入的名称，其余代码将正常工作

`

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']); 



 if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {



echo "The file ".  basename( $_FILES['uploadedfile']['name']). 
" has been uploaded";



 } else{


echo "There was an error uploading the file, please try again!";



 }


`

specify your directory path here

$target_path = "uploads/";

replace the name of file input with uploadedfile and rest code will work fine

`

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']); 



if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {



echo "The file ".  basename( $_FILES['uploadedfile']['name']). 
" has been uploaded";



} else{


echo "There was an error uploading the file, please try again!";



}`

正如下面的代码是工作示例：

中创建一个名为“myfolder”的文件夹

首先在 htdocs 文件夹[img_uploader.php]

<?php
$target_path = "myfolder/";

$target_path = $target_path . basename( $_FILES['fileToUpload']['name']); 

if(move_uploaded_file($_FILES['fileToUpload']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['fileToUpload']['name']). 
    " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
}
?>

As Your Code below is working example:

first create a folder with name "myfolder" in your htdocs folder

[img_uploader.php]

<?php
$target_path = "myfolder/";

$target_path = $target_path . basename( $_FILES['fileToUpload']['name']); 

if(move_uploaded_file($_FILES['fileToUpload']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['fileToUpload']['name']). 
    " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
}
?>

在工作目录中上传是可以的，但是，同时在数据库中上传是注意工作的，有人可以解决这个问题吗？亲切地。

函数 doInsert(){
if(isset($_POST['保存'])){
if ( $_POST['BRANCHNAME'] == "" || $_POST['BRANCHLOCATION'] == "" || $_POST['BRANCHCONTACTNO'] == "" ) {
$messageStats = false;
message("所有字段均为必填！","错误");
重定向('index.php?view=add');
}其他{
$branch = 新分支();
$branch->BRANCHNAME = $_POST['BRANCHNAME'];
$branch->BRANCHLOCATION = $_POST['BRANCHLOCATION'];
$branch->BRANCHCONTACTNO = $_POST['BRANCHCONTACTNO'];
$branch->BRANCHLEVEL = $_POST['BRANCHLEVEL'];
$branch->BRANCHSTATUS = $_POST['BRANCHSTATUS'];
$branch->BRANCHMANAGER = $_POST['BRANCHMANAGER'];
$branch->BRANCHDESCRIPTION = $_POST['BRANCHDESCRIPTION'];
//$branch->PICLOCATION = $_POST['PICLOCATION'];

        $branch->_FILES       = $_POST['PICLOCATION'];

        $file =$_FILES['PICLOCATION'];

        $filename = $file['name'];
        $filepath = $file['tmp_name'];
        $fileerror = $file['error'];

        if ($fileerror == 0) {
            $destfile = 'photos/'.$filename;
            move_uploaded_file($filepath, $destfile);


        
        

        $branch->LATITUDE                       = $_POST["LATITUDE"];
        $branch->LONGITUDE                      = $_POST["LONGITUDE"];
        $branch->create();

        message("New Branch created successfully!", "success");
        redirect("index.php");
        
    }
    }

}
}

In the working directory is fine work upload but, uploading in the database at the same time is note working any one solve this problem? kindly.

function doInsert(){
if(isset($_POST['save'])){
if ( $_POST['BRANCHNAME'] == "" || $_POST['BRANCHLOCATION'] == "" || $_POST['BRANCHCONTACTNO'] == "" ) {
$messageStats = false;
message("All field is required!","error");
redirect('index.php?view=add');
}else{
$branch = New Branch();
$branch->BRANCHNAME = $_POST['BRANCHNAME'];
$branch->BRANCHLOCATION = $_POST['BRANCHLOCATION'];
$branch->BRANCHCONTACTNO = $_POST['BRANCHCONTACTNO'];
$branch->BRANCHLEVEL = $_POST['BRANCHLEVEL'];
$branch->BRANCHSTATUS = $_POST['BRANCHSTATUS'];
$branch->BRANCHMANAGER = $_POST['BRANCHMANAGER'];
$branch->BRANCHDESCRIPTION = $_POST['BRANCHDESCRIPTION'];
//$branch->PICLOCATION = $_POST['PICLOCATION'];

        $branch->_FILES       = $_POST['PICLOCATION'];

        $file =$_FILES['PICLOCATION'];

        $filename = $file['name'];
        $filepath = $file['tmp_name'];
        $fileerror = $file['error'];

        if ($fileerror == 0) {
            $destfile = 'photos/'.$filename;
            move_uploaded_file($filepath, $destfile);


        
        

        $branch->LATITUDE                       = $_POST["LATITUDE"];
        $branch->LONGITUDE                      = $_POST["LONGITUDE"];
        $branch->create();

        message("New Branch created successfully!", "success");
        redirect("index.php");
        
    }
    }

}
}
