Tengo este codigo para subir archivos que aunque sea un poco extrano aveces funciona y a veces no.
Es para subir archivos tipo imagen. MI hosting es Linux.
Cuales son las lineas que debo descomentar o agregar al php.ini para asegurar no tener problemas para subir archivos . Yo agregue al php.ini
upload_tmp_dir = /tmp
file_upload = On
upload_max_filesize = 2M
??DEBO AGREGAR ALGUNA MAS ??
En la misma raiz donde esta este archivo estan las carpetas "uploads" y "tmp".
Aqui dejo el codigo tal cual como lo tengo:
