Ciao a tutti,
so che sicuramente è una banalità ma ancora non mi sono trovato davanti ad un problema simile. Quando apro la pagina, mi restituisc equesto messaggio di errore:
codice:
Notice: Undefined index: searching in /data/vhosts....

Notice: Undefined index: find in /data/vhosts....

Se eseguo lo script mi restituisce errore 404


[PHP]
<h2>Search</h2>
<form name="search" method="post" action="<?=$PHP_SELF?>">
Seach for: <input type="text" name="find" /> in
<Select NAME="field">
<Option VALUE="fname">First Name</option>
<Option VALUE="lname">Last Name</option>
<Option VALUE="info">Profile</option>
</Select>
<input type="hidden" name="searching" value="yes" />
<input type="submit" name="search" value="Search" />
</form>

<?
$searching = $_REQUEST['searching'];
$find = $_REQUEST['find'];

//This is only displayed if they have submitted the form
if ($searching =="yes")
{
echo "<h2>Results</h2>

";

//If they did not enter a search term we give them an error
if ($find == "")
{
echo "

You forgot to enter a search term";
exit;
}

// Otherwise we connect to our Database
mysql_connect("mysql.yourhost.com", "user_name", "password") or die(mysql_error());
mysql_select_db("database_name") or die(mysql_error());

// We preform a bit of filtering
$find = strtoupper($find);
$find = strip_tags($find);
$find = trim ($find);

//Now we search for our search term, in the field the user specified
$data = mysql_query("SELECT * FROM users WHERE upper($field) LIKE'%$find%'");

//And we display the results
while($result = mysql_fetch_array( $data ))
{
echo $result['fname'];
echo " ";
echo $result['lname'];
echo "
";
echo $result['info'];
echo "
";
echo "
";
}

//This counts the number or results - and if there wasn't any it gives them a little message explaining that
$anymatches=mysql_num_rows($data);
if ($anymatches == 0)
{
echo "Sorry, but we can not find an entry to match your query

";
}

//And we remind them what they searched for
echo "Searched For: " .$find;
}
?>


Mi potreste aiutare spiegandomi dove sta il problema?

Grazie
