I tried using an ereg on a textbox once sent through the post. For example it always goes to false no matter what the input was, even if it was in the correct state.

Is my ereg expression ok, for letters and caps, numbers and spaces and 5-20 chars

PHP Code:

if(ereg("^[a-zA-Z0-9][:space:]{5,20}$", $_POST['stadium_name']))
{
return "True";
} else {
return "False";
} 


My guess:

PHP Code:

if(ereg("^[a-zA-Z0-9\040]{5,20}$", $_POST['stadium_name'])) 


Your RE is looking for a single letter or number followed by 5 to 20 spaces.

You probably want "^[a-zA-Z0-9]{5,20}[:space:]$"

fava

nope still doesn't work!

Letters in any order and caps!
Numbers in any order!
Allow spaces any where!
Must be between 5 - 20 chars!

Any ideas on a ereg???

Ehm.
Mine works.
I tested it.

oh i didnt spot urs! i used fava!

your one still doesnt work!

It doesnt except Redbridge Park

Uhm.
That's really weird, because it does accept it for me. :P

If you want spaces in the name then you need:

"^[a-zA-Z0-9 \t]{5,20}$"

Note: php4 ereg does not support [:space:]

cheers im using php5

Still doesn't except Redbridge Park

Mine does, I'm sure of it.
I've tested in PHP in both ereg and preg_match, and I've also tested it in various RegEx programs.
They all match Redbridge Park with the pattern I provided.

Interesting, it should work.

Do you have a trailing newline in the string that is causing the match to fail?

There is a simple interactive regex matcher at http://www.gskinner.com/RegExr/

Try that ind let me know what it shows.

the [a-zA-Z0-9 \t] bit works but it doesnt work once i put the {5-20} bit in!

How do i make it set the min limit of 5 chars and the max limit of 20 chars?

Thats odd, in the regex matcher that I gave a link for it does match. The only thing I can think of is that there is newline or some other whitespace at the end of the string.

Does ^[a-zA-Z0-9 \t]{5,20}$ work?
Does ^[a-zA-Z0-9 \t]{5,20} work?
Does ^[a-zA-Z0-9 \t]$ work?
Does ^[a-zA-Z0-9 \t]{5,20}\n$ work?
Does ^[a-zA-Z0-9 \t]{5,20}.$ work?

fava

It's {5,20} not {5-20}.
Maybe that's your mistake, because I'm sure mine works as well.

Nah still doesn't work with the , instead of -

PHP Code:

// Change Stadium Name
if(isset($_POST['change_stadium']))
{
if($_POST['stadium_name'] != "" && $_POST['stadium_name'] != $_SESSION['stadium_name'])
{
if($_SESSION['change_stadium'] == 1)
{
if(ereg("^[a-zA-Z0-9 \t]{5,20}$", $_POST['stadium_name']))  
{
$num_rows = mysql_num_rows(mysql_query("SELECT * FROM `manager__teams` WHERE `stadium_name` = '" . $_POST['stadium_name'] . "'"));
if($num_rows == 0)
{
echo expense($_SESSION['team_id'], "other", 50000);
mysql_query("UPDATE `manager__teams` SET `stadium_name` = '$stadium_name', `change_stadium` = '1' WHERE `id` = '" . $_SESSION['team_id'] . "'");
$stadium = $_SESSION['stadium_name'];
$_SESSION['stadium_name'] = $stadium_name;
$note = "Your stadium is now known as $stadium_name.";
} else {
$note = "That stadium name is already taken please choose another name.";
}
} else {
$note = "You have already changed your stadium name this season. Please wait until next season to change it again.";
}
} else {
$note = "Stadium names can only contain letters, numbers and spaces and must be 5-20 characters long.";
}
}
}
