I have this:
$str = ereg_replace(“[^A-Za-z0-9]”, “”, $str);
How can I allow spaces to remain in $str?

The spaces should remain for that RegEx, can you provide an example where they don’t? It will help us see what you’re expecting to happen.
Actually just realised I have another function str_replacing the spaces for dashes and this happens before the function above!
Actually I was incorrect. So yes still removing spaces and I’m not sure why. I apply this to the posted field input:
$formfieldvalue = mysql_real_escape_string(htmlspecialchars(clean($_POST[$formfield])));
function clean($str){
$str = ereg_replace("[^A-Za-z0-9]", "", $str);
return $str;
}
Sorry, I was wrong.
Here you go, note the \s for space and the migration to [FONT=courier new]preg_*
[/FONT]
<?php
function clean($value){
return preg_replace('~[^0-9a-z\\s]~i', '', $value);
}
$string = 'Hello, I\\'m Anthony';
var_dump(
clean($string)
);
/*
string(16) "Hello Im Anthony"
*/
Ha! I had just found this same code via Google! Many thanks though
