Re: Re: [PHP] is_numeric questions - followup
From: Jeff Oien [EMAIL PROTECTED] Does is_numeric include commas decimals and dollar signs? How do I use this to error check form data? I'm having a hard time figuring out what the correct syntax is for that application. Thanks. Jeff I think what I should have asked is how to tell if something is not numberic. if(!is_numeric($var)) ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: Re: [PHP] php5 and object
From: Stephen Sadowski [EMAIL PROTECTED] Subject: Re: [PHP] php5 and object http://us4.php.net/manual/en/language.oop5.abstract.php The short is that you can't do anything more than define a function in an abstract class. IIRC, change abstract to interface, and you'll probably be okay. Switch that around. Interfaces cannot contain anything but function definitions. Abstract classes can contain functions that'll be inherited. ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Problem with $_SERVER['PHP_AUTH_USER'] and $_SERVER['PHP_AUTH_PW']
From: Mark Collin [EMAIL PROTECTED]
Does anybody have any ideas on how I can prevent caching of
$_SERVER['PHP_AUTH_USER'] and $_SERVER['PHP_AUTH_PW'], or clear them?
You can't clear them; they're sent by the browser. It'll keep resending the same
values and you're script will authenticate. Only way to get rid of it is to close the
browser.
You could attempt to force the user to log with a known bad username and password by
using a link or header redirect.
header('Location: http://username:[EMAIL PROTECTED]');
Your login script should check for these known values and can react accordingly. You
know they are bad, so you can either present them with another dialog to log back in
or you can just not send any authentication headers and show them a successfully
logged out page.

Re: [PHP] Alternative to stripslashes(htmlentities($textstring))
From: gohaku [EMAIL PROTECTED] I was just curious if there is another function that does the same job as stripslashes(htmlentities($textstring)). Nope. Do it that way. Or you can turn off magic_quotes_gpc, which is probably the reason you have to run stripslashes(). ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: RE: [PHP] Validating form field text input to be a specific variable type
From: Merritt, Dave [EMAIL PROTECTED]
Okay seems to makes sense, but when I do the following it doesn't appear to
be working correctly, or I'm viewing my logic incorrectly one:
if ( (int)$PageOptions['Default'] == $PageOptions['Default'] ) {
This works:
if(strcmp((int)$PageOptions['Default'],$PageOptions['Default'])==0)

Re: [PHP] For your reference, how to validate dynamic form fields.
From: Hawkes, Richard [EMAIL PROTECTED]
Just spent far too long trying to figure out how to do this, so I thought I'd
pass it on to you great guys, in case you need it for the future.
I used PHP to create multiple form rows, each one numbered:
?
for ($i =1; $i = 20; $i++) {
echo(input type=text name=userId$i maxlength=5/br/);
}
?
Use arrays. It'll make your life easier.
echo input type=\text\ name=\userId[$i]\ maxlength=\5\/br /);
You can still reference the element in Javascript, just by name or whatever you call
it.
form.element['userId[1]'] (or something like that).
You show a Javascript validation. Remember that this is easily bypassed so you also
need to validate the numbers on the PHP side.
?php
foreach($_POST['inputId'] as $id)
{
if(!is_numeric($id))
{ echo $id is invalid!; }
}
?
