Input checking

[Anon]

Lets say if i have a input (from a form) of

name
phone

<?
if($name ==\"|\"|$phone ==\"|\")
{
echo \"ERROR<BR>They key | is NOT a valid entry Go back and change it\";
Die;
}else{
}
?>

Works ok !!!
for if a use JUST puts \"|\"

BUT !!!!
If a user puts
Zeddy|myname

It will allow it,,, how can i make it look for a var anywhere in a input ?

}

yes, if you don't care to know which of the $name,$phone or $more contains the "|".

you can simply concatenate the strings to make one large string that is then checked:

preg_match("/|/",$name.$phone.$more)

Got any ideas ?

Fatal error: Call to unsupported or undefined function preg_match() in Z:/xxx.com/xxx/edit.html on line 2

Sure: you don't have the PREG stuff compiled into your php. But don't despair, the less-capable ereg() is still sufficient to do what you want here.

In fact, if all you're doing is looking for a single instance of a single literal character, strstr() is good enough for that, and will certainly be faster than any regex.

The problem is the PHP that i have,,, i have version 3,
I tried 4 BUT !!!
I am having problems with that (But that command works with 4)

The problem i am having with 4 is I used to called PHP
as
D:\php3\php.exe C:\template.html
IN the Filter (to get headers and footers)
it worked FINe under 3,,,
But 4 it don't work

Got any ideas ?
