Hmmmm.... PHP code
OK, I've never uploaded a file to a server, but I've downloaded a few. I don't believe InternetOpenURL will work here, as that function seems to be used in downloading direct link files. In any case, i don't know anything so here's a few APIs I think you should get familiar with.

' Allow access to the Inet functions
InternetOpen
 
' To connect to a remote computer. Allows for Authentication via username and password parameters
InternetConnect
 
' Create and Open a HTTP Request. lpszVerb will most likely be PUT to upload a file. GET is used to download the file
HttpOpenRequest
 
' Send the request. Non-zero means success.
HttpSendRequestEx
 
' Never used these :p
InternetWriteFile
 
HttpEndRequest
 
' For cleanup of open Internet handles
InternetCloseHandle

Look those up on MSDN. I would try to make an example, but dont really know where i'd up the file.

i believe it is to do with permissions on the server, but i was unable to resolve the problem

Hi westconn1 ,

i did chmod the uploads folder on remote server & it's working for me here on my local machine

can you tell me which permissions are you talking about ?

Thanks

[westconn1]

here is the php i was using to return results to browser

<?php
foreach($_POST as $key => $value){
 
 
  if($value != ""){
    $message .= $key. " --------- " . $value. "\n" ;
  
    echo   $key . " ----- " . $value. "<br>";
   }else{
    $error = true;
    
  }
}
foreach($_FILES as $myfile => $xxx){
foreach($xxx as $uploadedfile => $name){
echo $uploadedfile . " ----- " . $name . "<br>";
}
 }
$target_path = getcwd(). "/upload/";
 
echo $_FILES["uploadedfile"]["tmp_name"]."<br>";
echo exec('whoami');
chmod($_FILES["uploadedfile"]["name"],0777);
echo substr(sprintf('%o', fileperms($_FILES["uploadedfile"]["tmp_name"])), -4)."<br>";
 
 
// ulink($_FILES["uploadedfile"]["tmp_name"]);
 
echo $_FILES["uploadedfile"]["name"]."<br>";
 
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']); 
  //    copy($_FILES["uploadedfile"]["tmp_name"], $target_path . $_FILES["uploadedfile"]["name"]);
echo $target_path."<br>";
if(move_uploaded_file($_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!";
}
 
 
?>

i have not played with it for a while, i was just using a file input for testing

Some php will go under as php scripts. and if your having a site hosted you wonna make sure your provider allows php scripts to be used. I believe that was 1 of my problems otherwise the code in 1 topics which is where u got that code from works perfectly.

[westconn1]

the php code ran and echoed everything back to the browser, but no file was uploaded, whether is used moveuploadedfile or copy
other php scripts work correctly
the file permissions returned to the browser were not changed by the chmod

Thanks Guy for your answer . Unfortunately, after reading & googling i think the get method on that will not work at least on that way..

and yes the host is Linux one so PHP is working fine

so i moved to another way using POST data which will require 1 html file and 1 php file & http post header on vb6 (which i have problem right now )



now i'am trying to use http header using InternetOpenurl API to i can upload that file using post data

hope someone can help me

Thanks

[westconn1]

that was more or less what i started with, then added to for debugging purposes,
which showed every thing as correct, but the file was not saved

you mean you didnt get it working ?

i really dunno what's wrong with that code and Pezster said it's working how !!!??

Thanks

This code might / might not work. Last time i tryed it, it didn't work but I believe that was due to my webhost not allowing phpscripts to be used considering my friend had another site and this exact code did work.

<?php

//Put this php upload script in your apache php webserver.
//Set the url to this script in your vb upload client

$location = "";      //Left blank if upload in same folder
$max_size = 1000000; //File upload size

print("$value1 $value2\r\n"); //Check for extra posted variable - u can add ur own here

//This loop here will save ur file to the server
for ($num = 1; $num < $slots+1; $num++){

    $event = "Success";
    
    // Check if upload for field is required
    if (! $_FILES['upload'.$num]['name'] == ""){
      if ($_FILES['upload'.$num]['size'] < $max_size) {        
        move_uploaded_file($_FILES['upload'.$num]['tmp_name'],$location.$_FILES['upload'.$num]['name']) or $event = "Failure";
       } else {
        $event = "File too large!";
       }
       print("Uploading File $num $event\r\n");
    }
  }

?>

Private Sub Command1_Click()

Dim iArray

'Set your filename to upload here
iArray = Array("image1.jpg", "image2.jpg", "image3.jpg")

'Set path to php upload script here
Text1.Text = UploadFiles(iArray, "http://site/getfile.php", App.Path, Text2.Text)

End Sub

[Pezster]

If that code doesnt code work that I posted above theres another way around it if you have a website easier idk just all depends if you dont wonna login ftp like i did or not. Theres php scripts that allow user input on an HTML page, search for file, press upload button. You can have the vb program fill in all thoose fields and done, just adds an extra HTML page to your site.

The path $target_path = "uploads/"; is pointing to an absolute path in the remote webserver is it? check that out.. if the remote webserver you are trying to upload to is a shared webhosting server then the path for the PHP script has to be declared properly. I have tried this before for file uploads.

I had to use the path as below to get the file upload going...

/home/<loginname>/public_html/

in your case it would be possible to verify the actual path for upload using the filemanager console the web service provider would have provided to you. I would suggest you use complete path instead of relative path for uploads as there will be no confusion. If you have doubt over permissions try setting the path to tmp folder of the remote server which would probably be /home/<loginname>/tmp

[westconn1]

i returned the target path to the browser, certainly looked correct, for my server
the current user for the php script returns apache chmod did not appear to change the permissions for the file, maybe apache does not have enough permissions to change the file permissions

[killer7k]

Thanks Guy for your answer . Unfortunately, i did tried the first code i did put on 3 different host & all are chmoded but none work (work for me on my local machine)

however i hope someone can help me with post data with the code i did post for html & php file

@Pezster

where is UploadFiles Function ??

my idea was to use http post header data but dont know how to on vb6

Thanks & still waiting someone can help

[Pezster]

what do you mean by UploadFiles function? Php you really just open the site and write w.e the required informtation to the end of the url ex. Text1.Text = UploadFiles(iArray, "http://site/getfile.php", App.Path, Text2.Text)
