Hola, tengo un script php en i página para subir imágenes al servidor que sólo funciona a veces y no se por qué. Quiero que el tamaño máximo sea 200KB y aparece 100. Además me gustaría incluir en el formulario campos de datos y que también necesito. Si alguien puede ayudarme, muchas gracias. La dirección es
www.zerotwowear.com, en "gallery/sen your photos".
El script es el siguiente, y como he dicho, a veces funciona bien:
Herni
Código PHP:
<?php
/*
---Description -----------------------------------------------------
The Super Global Variable $_FILES is used in PHP 4.x.x.
$_FILES['upload']['size'] ==> Get the Size of the File in Bytes.
$_FILES['upload']['tmp_name'] ==> Returns the Temporary Name of the File.
$_FILES['upload']['name'] ==> Returns the Actual Name of the File.
$_FILES['upload']['type'] ==> Returns the Type of the File.
So if I uploaded the file 'test.doc', the $_FILES['upload']['name']
would be 'phptut.doc' and $_FILES['upload']['type'] would be 'application/msword'.
