Quick Image Question

Anon

Doing a Mysql database thing that can store images as part of a user registration thing(give your info and can browse to select a picture as well). Anyways, It works Perfect, as long as they select a picture. How can i make it so if no pic is selected, it will do an action, such as set a variable to 0, or chose a default pic....heres the code:

<?
$db = mysql_connect("localhost", "root", "XXXXXXX");
mysql_select_db("screenshots");
$data = addslashes(fread(fopen($form_data, "r"),
filesize($form_data)));

$result=MYSQL_QUERY("INSERT INTO screens
(description,bin_data,filename,filesize,filetype) ".
    "VALUES
(0,'$data','$form_data_name','$form_data_size','$form_data_type')");

$imageid= mysql_insert_id();

would form_data_size be = 0 if there was non selected?

It craps out if no pic is selected...

form data type: 'application/octet-stream'form data size: '0'form data bane: ''
Warning: fopen("none","r") - No such file or directory in /usr/local/apache/htdocs/php/screens/test2.php on line 16

Warning: Supplied argument is not a valid File-Handle resource in /usr/local/apache/htdocs/php/screens/test2.php on line 17

anyway i can prevent it from doing this if no pic is choosen?

simple answer

if($filename)
{
$db = mysql_connect("localhost", "root", "XXXXXXX");
mysql_select_db("screenshots");
$data = addslashes(fread(fopen($form_data, "r"),
filesize($form_data)));

$result=MYSQL_QUERY("INSERT INTO screens
(description,bin_data,filename,filesize,filetype) ".
"VALUES
(0,'$data','$form_data_name','$form_data_size','$form_data_type')");

$imageid= mysql_insert_id();
}

else

{
echo("Please upload a image");

}

or if you mean like the select a pic for there icon then

if(!$icon)
{
$icon = "default.gif";
}
