Opplastingsscript for flere filer

Garreth · 11. oktober 2005

Det ble postet en link til et javascript i webkafeen som lot deg laste opp flere filer på en gang. Men jeg trenger et serverside script som tar seg av overførselen.

Jeg har prøvd å modifisere et enkelt opplastingsscript som jeg fant på Hotscripts, men det skjer ikke noe når jeg trykker "submit/upload". Jeg har prøvd å bytte ut "userfile" med "my_file_element" i phpscriptet, men jeg har sikker byttet det ut feil en eller annen plass siden det ikke fungerer å laste opp.

Kan noen hjelpe meg med dette?

Eksempel fra opplastingsscript med flere objekter:

	<!-- Include the javascript -->
<script src="multifile_compressed.js"></script>
</head>

<body>

<!-- This is the form -->
<form enctype="multipart/form-data" action="your_script_here.script" method = "post">
<!-- The file element -- NOTE: it has an ID -->
<input id="my_file_element" type="file" name="file_1" >
<input type="submit">
</form>
Files:
<!-- This is where the output will appear -->
<div id="files_list"></div>
<script>
<!-- Create an instance of the multiSelector class, pass it the output target and the max number of files -->
var multi_selector = new MultiSelector( document.getElementById( 'files_list' ), 20 );
<!-- Pass in the file element -->
multi_selector.addElement( document.getElementById( 'my_file_element' ) );
</script>
</body>
</html>

Javascript

/**
* Convert a single file-input element into a 'multiple' input list
*
* Usage:
*
*   1. Create a file input element (no name)
*      eg. <input type="file" id="first_file_element">
*
*   2. Create a DIV for the output to be written to
*      eg. <div id="files_list"></div>
*
*   3. Instantiate a MultiSelector object, passing in the DIV and an (optional) maximum number of files
*      eg. var multi_selector = new MultiSelector( document.getElementById( 'files_list' ), 3 );
*
*   4. Add the first element
*      eg. multi_selector.addElement( document.getElementById( 'first_file_element' ) );
*
*   5. That's it.
*
*   You might (will) want to play around with the addListRow() method to make the output prettier.
*
*   You might also want to change the line 
*       element.name = 'file_' + this.count;
*   ...to a naming convention that makes more sense to you.
* 
* Licence:
*   Use this however/wherever you like, just don't blame me if it breaks anything.

Finn ut hva du skal gjøre med én fil, så har du funnet ut hva du skal gjøre med alle. Javascriptet er uvesentlig i serverside-sammenheng. Hvis du er usikker på hva som blir sendt til serveren, kan du kjøre print_r på $_FILES, for eksempel.

<?php
print_r($_FILES);
?>

Garreth · 11. oktober 2005

Merkelig, for jeg klarer å laste opp når jeg ikke har javascriptet på. Når jeg har det på, så klarer jeg å hente inn filer, men når jeg trykker upload så skjer det ingenting (siden bare refresher seg)

med print_r($_FILES); får jeg

Array ( [file_0] => Array ( [name] => AA050372.jpg [type] => image/jpeg [tmp_name] => /var/tmp/phprDKtdS [error] => 0 [size] => 29779 ) [file_1] => Array ( [name] => [type] => [tmp_name] => [error] => 4 [size] => 0 ) )

Jeg skjønner desverre ikke så mye av det :roll:

Edit: Jeg hadde visst glemt å ta med skjemaet som er i upload scriptet

   <font color=red><?=$_REQUEST[message]?></font>
  <br>
  <form name="upload" id="upload" ENCTYPE="multipart/form-data" method="post">
    Upload File <input type="file" id="userfile" name="userfile">
    <input type="submit" name="upload" value="Upload">
  </form>

  <br><b>My Files</b>
  <hr width=70%>
  <?=$filelist?>
  <hr width=70%>

Jeg tror feilen skjer fordi at både "name" og "id" har samme navn, men hvis jeg bytter ut "name" med noe annet både i skjemaet og i php koden så laster den ikke opp lenger. Så hvis noen ser hva som er galt her så hadde det vært veldig fint!

Det du fikk i print_r betyr at du fikk lastet opp én fil (AA050372.jpg), mens en annen fil, som ikke har noe filnavn, fikk error #4 (No file was uploaded).

Garreth · 12. oktober 2005

Nå får jeg til å laste opp mens jeg har på javascriptet. Det lister opp som normalt, men når jeg trykker "upload" så kommer bare den første filen med.

Edit: Jeg får heller ikke noe error fra print_r($_FILES); heller når jeg laster opp.

Edit 2:

Jeg fant et annet script som ikke brukte javascript. Bruker heller det.

Dette er koden jeg bruker nå:

                  ,'image/png','application/msword');

//Allowable file ext. names. you may add more extension names.            
$FILE_EXTS  = array('.zip','.jpg','.png','.gif','.pdf','.rar'); 

//Allow file delete? no, if only allow upload only
$DELETABLE  = true;
