    Upload e ridimensionamento immagini

    Qualcuno mi può aiutare ha modificare questo codice per l'upload delle immagini.

    Attualmente funziona in questo modo:
    Viene ritagliato un quadrato con lato uguale alla lunghezza del lato più corto della foto caricata:
    Dopodiché il quadrato viene ridotto a 120x120 pixel e poi salvato nella cartella "foto".

    E qui mi sono bloccato...

    Adesso vorrei far si che oltre a salvare la miniatura da 120x120, mi salvasse anche un altra miniatura da 200x200 e poi una copia dell'immagine originale.

    ES:
    L'utente carica una foto con nome: foto.jpg

    nella cartella foto ritrovo:
    foto.jpg (dimensioni originali)
    foto_med.jpg (240x240)
    foto_sma.jpg (120x120)

    Potete aiutarmi... Grazie

    Questo è il codice:
    "... se volete provarlo il codice è completo, quindi salvandolo in un file .php e avviandolo da php fuziona"

    [php]
    <?php ini_set("memory_limit", "200000000"); // for large images so that we do not get "Allowed memory exhausted"?>

    Ciao

    ti allego solo parte php, è una soluzione diversa a quello che hai tu nel codice.
    Questo ti salva la foto in originale, ti crea 2 resize, uno da 120 e uno da 240 come hai specificato.

    P.S. non ho testato il codice che ti allego.

    
<?php ini_set("memory_limit", "200000000"); // for large images so that we do not get "Allowed memory exhausted"?>
<?php
// upload the file
if ((isset($_POST["submitted_form"])) && ($_POST["submitted_form"] == "image_upload_form")) {
    
// file needs to be jpg,gif,bmp,x-png and 4 MB max
if (($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg" || $_FILES["image_upload_box"]["type"] == "image/gif" || $_FILES["image_upload_box"]["type"] == "image/x-png") && ($_FILES["image_upload_box"] < 4000000))
{

$remote_file = "foto/".$_FILES["image_upload_box"]["name"];
chmod($remote_file,0644);

// carico la foto originale
move_uploaded_file($_FILES['image_upload_box']['tmp_name'], $remote_file);


                // procedo a ridimensionare la foto per 240 e per 120

                include("include/class.image-resize.php");
                $obj = new img_opt();
                $obj->max_width(240);
                $obj->max_height(240);
                $obj->image_path($remote_file);
                $obj->image_resize();
                
                $obj2 = new img_opt();
                $obj2->max_width(120);
                $obj2->max_width(120);
                $obj2->image_path($remote_file);
                $obj2->image_resize();
 
header("Location: submit.php?upload_message=image uploaded&upload_message_type=success&show_image=".$_FILES["image_upload_box"]["name"]);
exit;
 } else{
header("Location: submit.php?upload_message=make sure the file is jpg, gif or png and that is smaller than 4MB&upload_message_type=error");
exit;
}
}
?>

    questa è la classe utilizzata per il resize (class.image-resize.php).

    
<?PHP

    function image_path($path)

        $this->path = $path;
    }
    function get_mime()
    {
        $img_data = getimagesize($this->path);
        $this->mime = $img_data['mime'];

    Ciao

    si hai ragione, macava qualche cosa.

    provalo così, io non l'ho provato, attendo alle riche dove vengono definiti i nomi dei 3 file, devi creare le cartelle dove andranno le foto interessate.

    
<?php ini_set("memory_limit", "200000000"); // for large images so that we do not get "Allowed memory exhausted"?>
<?php
// upload the file

{

$remote_file_full = "foto/full/".$_FILES["image_upload_box"]["name"];
$remote_file_240 = "foto/resize_240/".$_FILES["image_upload_box"]["name"];
$remote_file_120 = "foto/resize_120/".$_FILES["image_upload_box"]["name"];


chmod($remote_file_full,0644);

// carico la foto originale
move_uploaded_file($_FILES['image_upload_box']['tmp_name'], $remote_file_full);

copy($remote_file_full,$remote_file_120);


                // procedo a ridimensionare la foto per 240 e per 120

                include("include/class.image-resize.php");

exit;
 } else{

    Ho creato le cartelle in questo modo, nella cartella "www" di easyphp ho creato le cartelle:
    foto/full
    foto/resize_240
    foto/resize_120

    però mi da comunque errore:

**Fatal error**: Class 'img_opt' not found in **C:\Program Files (x86)\EasyPHP-5.3.1\www\submit.php** on line **28**

    Andando a controllare le cartelle, al loro interno c'è l'immagine che ho caricato, però non ridimensionata.

    attenzione che la riga 27 ti dice che non trova il file class.image-resize.php quindi controlla bene il percorso se è corretto.

    poi togli le righe 15, 16 e 17

    Rieccomi, mi scuso se rispondo solo ora ma avevo accantonato l'upload delle immagini per dare riorità ad altre parti del progetto...Ho ripreso in mano tutte le prove e i problemi persistono, anche con le ultime modifiche non riesco a risolvere il problema; fino al resize della singola immagine tutto ok, mentre i 2 file che mi hai passato non riesco a farli funzionare.
    Ti chiedo gentilmente se quando hai tempo puoi fare un test e vedere se capisci dov'è il problema, io non so più dove sbattere la testa.

    Grazie
