Warning: fopen(/var/www/html/mexternet/tienda/catalogues/catalog_1.pdf): failed to open stream: No such file or directory in /var/www/html/mexternet/catalog/admin/pdf_fpdf.php on line 1052
FPDF error: Unable to create output file: /var/www/html/mexternet/tienda/catalogues/catalog_1.pdf

Y .. estás seguro que exite ese archivo con ese nombre en esa ruta?:
/var/www/html/mexternet/tienda/catalogues/catalog_1.pdf

Un saludo,

Si lo que intestas es crear el archivo , verifica los permisos del directorio

SI fuece porblemas de permisos diria eso en el error.

El script genera un PDF y luego tiene que abrirlo?, creo que ese es el error, el script no esta generando el archivo pero igual intenta abrirlo...

Fijate poniendo la URL entera al fopen...

pues no aqui es donde me marca el error por favor AYUDAAAA¡¡¡¡

Código PHP:

      switch($dest)

    {

        case 'I':

            //Send to standard output

            if(isset($HTTP_SERVER_VARS['SERVER_NAME']))

            {

                //We send to a browser

                Header('Content-Type: application/pdf');

                if(headers_sent())

                    $this->Error('Some data has already been output to browser, can\'t send PDF file');

                Header('Content-Length: '.strlen($this->buffer));

                Header('Content-disposition: inline; filename='.$name);

            }

            echo $this->buffer;

            break;

        case 'D':

            //Download file

            if(isset($HTTP_SERVER_VARS['HTTP_USER_AGENT']) and strpos($HTTP_SERVER_VARS['HTTP_USER_AGENT'],'MSIE'))

                Header('Content-Type: application/force-download');

            else

                Header('Content-Type: application/octet-stream');

            if(headers_sent())

                $this->Error('Some data has already been output to browser, can\'t send PDF file');

            Header('Content-Length: '.strlen($this->buffer));

            Header('Content-disposition: attachment; filename='.$name);

            echo $this->buffer;

            break;

        case 'F':

            //Save to local file            

aqui marca el    ------->>$f=fopen($name,'wb');

error            if(!$f)

                $this->Error('Unable to create output file: '.$name);

            fwrite($f,$this->buffer,strlen($this->buffer));

            fclose($f);

            break;

        case 'S':

            //Return as a string

            return $this->buffer;

        default:

Pero que "error" te marca? (textual)

Un saludo,

FuLaNo_ · #8 (**permalink**) 02/12/2004, 11:59

ya lo he dicho, para mi el problema es que no existe el archivo, por ende, FOPEN es imposible...

Warning: fopen(/var/www/html/mexternet/tienda/catalogues/catalog_1.pdf): failed to open stream: No such file or directory in /var/www/html/mexternet/catalog/admin/pdf_fpdf.php on line 1052
FPDF error: Unable to create output file: /var/www/html/mexternet/tienda/catalogues/catalog_1.pdf

Te esta diciendo claramente que el archivo no existe en el directorio indicado...
