Inserimento immagine

**seokey** · 18-10-2009, 17:07

Salve,

dal file "inserisci" inserisco campi dati del form e percorso immagine su db. L'immagine originale viene salvata correttamente nella cartella sul server e sul db viene salvato oltre al percorso corretto della cartella immagini un secondo percorso per la thumbnail che viene generata correttamente. Tuttavia, non viene salvato niente su una seconda cartella thumbs dove vorrei caricare la thumb creata. Allego codice file in questione. Grazie per suggerimenti.

<?php
require_once 'thumbnail.class.php';

include ("config.inc.php");

include ("connect.php");

include ("funzioni.php");

$thumbnail = new thumbnail;

if (!empty($_REQUEST['submit']))

{

$tmp = $_FILES['uploaded_file']['tmp_name'];

$org = $_FILES['uploaded_file']['name'];

if ($tmp)

{

$directory = 'uploads/'; // Upload files to here.

$prefix = 'uploaded_'; // Filename prefixes

$directory2 = 'thumbs/';

$image = $_FILES['uploaded_file']['name'];
$image2 = $_FILES['uploaded_file']['name'].$smlImage;
$percorso = "$directory";
$percorso2 = "$directory2";

$patch ="$percorso$image";

$patch2 ="$percorso2$image2";

$articolo = $_POST['articolo'];

$descrizione = $_POST['descrizione'];

$caratteristiche = $_POST['caratteristiche'];

$prezzo = $_POST['prezzo'];

$scadenza = $_POST['scadenza'];

$datains = $_POST['datains'];

// Upload all image files

$lrgImage = $thumbnail->generate($tmp, $org, $directory, $prefix.'lrg', 300); // large file

$medImage = $thumbnail->generate($tmp, $org, $directory, $prefix.'med', 200); // medium file

$smlImage = $thumbnail->generate($tmp, $org, $directory, $prefix.'sml', 100); // small file

if ($smlImage && $medImage && $lrgImage) // If all files are ok

{

$info = '

<fieldset>

<legend>Files uploaded successfully</legend>

[img]'.$lrgImage.'[/img]

[img]'.$medImage.'[/img]

[img]'.$smlImage.'[/img]

</fieldset>

';

}

}

else

{

$info = '

No file selected</p>';

}

}

$query="INSERT INTO promo (articolo,descrizione,immagine,immagine2,caratteri stiche,prezzo,scadenza) VALUES('$articolo','$descrizione','$patch','$patch 2','$caratteristiche','$prezzo','$scadenza')";

$result = mysql_query($query,$db);

Non vedo il codice della classe thumbnail che è proprio quello che dovevi mettere

**seokey** · 19-10-2009, 11:16

Ecco il codice della classe...

class thumbnail

{

var $sourceFile; // We use this file to create the thumbnail

var $originalFilename; // We use this to get the extension of the filename

var $destinationDirectory; // The Directory in question

var $destinationDirectoryFilename; // The destination filename

var $createImageFunction = '';

var $outputImageFunction = '';

function generate($sourceFile = "", $originalFilename = "", $destinationDirectory = "", $destinationDirectoryFilename = "", $width = -1, $height = -1)

{

if (!empty($sourceFile))

$this->sourceFile = $sourceFile;

if (!empty($originalFilename))

$this->originalFilename = $originalFilename;

if (!empty($destinationDirectory))

$this->destinationDirectory = $destinationDirectory;

if (!empty($destinationDirectoryFilename))

$this->destinationDirectoryFilename = $destinationDirectoryFilename;

if (!empty($width))

$this->width = $width;

if (!empty($height))

$this->height = $height;

list(, $this->extension) = explode('.', $this->originalFilename);

switch ($this->extension)

{

case 'gif' :

$createImageFunction = 'imagecreatefromgif';

$outputImageFunction = 'imagegif';

break;

case 'png' :

$createImageFunction = 'imagecreatefrompng';

$outputImageFunction = 'imagepng';

break;

case 'bmp' :

$outputImageFunction = 'imagewbmp';

break;

case 'jpg': case 'jpeg':

$createImageFunction = 'imagecreatefromjpeg';

$outputImageFunction = 'imagejpeg';

break;

default :

exit("Sorry: The format '{$this->extension}' is unsuported");

break;

}

$this->img = $createImageFunction($this->sourceFile);

list($this->org_width, $this->org_height) = getimagesize($this->sourceFile);

if ($this->height == -1)

{

$this->height = round($this->org_height * $this->width / $this->org_width);

}

if ($this->width == -1)

{

$this->width = round($this->org_width * $this->height / $this->org_height);

}

$this->xoffset = 0;

$this->yoffset = 0;

$this->img_new = imagecreatetruecolor($this->width, $this->height);

if ($this->img_new)

{

imagecopyresampled($this->img_new, $this->img, 0, 0, $this->xoffset, $this->yoffset, $this->width, $this->height, $this->org_width, $this->org_height);

Ciao,

piccolo consiglio, è meglio postare il codice nei tag bbcode php se vuoi che qualcuno comprenda il codice che posti e quindi sia invogliato a risponderti .

I tag bbcode php sono presenti nella casella di testo dove inserisci il testo (il bottone # a sinistra e i bottoni List e Quote a destra)
