RE: [Phplib-users] Patch to page.inc

[Rob H. <rob...@ws...>]

Yes, because repeated calls to login without cleaning up from the previous
ones leaves you with a url like
www.url.com?test=one&&&&&&&& which is ugly and I would bet would cause
problems with some browser out there...

[Phplib-users] Fwd: login_if ereg_replace improved

[Giancarlo <gia...@na...>]

For me this worked perfectly, with a single ereg_replace.



  function login_if( $trig ) { ### you can use auth->login_if("log") or "reg"
     if ( (bool) ($trig) ) {
        global $sess, $HTTP_SERVER_VARS;
       // Remove the "again=yes" from QUERY_STRING. This is required
       // because the login form will be submitted to the URL of this
       // page. This URL is constructed from $PHP_SELF and $QUERY_STRING.
       // So, we need to remove this parameter from QUERY_STRING or else
       // after the user submits a username and password, we will unauth
       // them before they even get logged in!
echo "BEFORE ". $HTTP_SERVER_VARS["QUERY_STRING"] ."<br>";

        $HTTP_SERVER_VARS["QUERY_STRING"] = ereg_replace(
         "(^|&)".$this->urlaction."=([[:alpha:]]*)(&|$)",
         "\\1", $HTTP_SERVER_VARS["QUERY_STRING"]);


echo "AFTER ". $HTTP_SERVER_VARS["QUERY_STRING"] ."<br>";


        if ( "$trig" == "logout" ) {

This is the regex being generated:

That's because it preg_replace()s all between { and }.
Solution: set remove_unknowns to off, this should be
sufficient (and, if there are any keywords that won't
get replaced, manually set_var() them with "KEYWORD" => ""
in order to remove it).

Same for stylesheets you have in your template (of
course one should define them via <link rel ...>
so that browsers can cache them).

[Phplib-users] Regex and Templates

[Rob H. <rob...@ws...>]

The regex {6,32} expression to match 6 to 32 times gets eaten by the
templates when remove_unknowns is on.  Is there a way to escape this or
something to prevent that?

Hi Rob

to check for alphanumeric chars between 6 and 25 chars use

"^[a-zA-Z0-9]{6,25}$"

This will bail if it's not like that.

You can drop A-Z bit depending on whether you're using ereg or eregi

RE: [Phplib-users] auth url question

[Rob H. <rob...@ws...>]

I disagree on two points.

1) I am new to the php-lib world, but from what I have been told, the 7.2
stuff is much more structured that the curent development stuff, and this is
the core issue that I see.

2) Registration may have special needs, but this is the point of having
local.inc.  Single, two-phase, and approval based registration can easliy be
offered as examples, and probably be used "off the shelf" in a lot of
circumstances...

[Phplib-users] Invalid Regex

[Rob H. <rob...@ws...>]

I am trying to validate the username field, and just to make up some
arbitrary rules, it has to be between 6 and 25 characters long and have no
punctuation.  So my valid regex looks something like "[A-Za-z0-9]{6,}" but
how do I tell it to fail if is has anything else?  Like invalid_regex =
"[^A-Za-z0-9]"?

Yes, by reading the documentation and finding get_start(),
get_element() (or ge()) and get_finish() which is exactly
that what you want to use:

$t->set_var(array(
	"MYFORM_TEXT" => $f->ge("txt"),
	"MYFORM_ADDRESS" => $f->ge("address"),
	.
	.

This is the current state of cvs.  These were the only changes made to the 
cvs and thus the cvs snapshot.

Perhaps unfortunately there hasn't been much discussion of this.  

All discussion has been about the dev snapshot which is good that 
development discussion is happening, but I would much rather see on a 
dedicated phplib developer list.

I created the dev snapshot because there didn't seem to be any discussion 
or feedback to the patches applied to sf.net.

[Phplib-users] OOHForms and Templates

[Rob H. <rob...@ws...>]

Guys,
  I am trying to figure out a way to combine OOHforms and Templates.  Use
login as an example I was thinking of.

Template

{formstart}
<table>
  <tr>
    <td>User Name:</td>
    <td>{usernameprompt}</td>
  </tr>
  <tr>
    <td>Password:</td>
    <td>{passwordprompt}</td>
  </tr>
  <tr>
    <td collspan="2">{submitbutton}</td>
  </tr>
</table>
{formfinish}


Then buffering the output to calling start(), show_element(), and finish()
into the appropriate variable.  Is there a better way of doing this?

RE: [Phplib-users] auth url question

[Rob H. <rob...@ws...>]

The more I think about this, the less I agree, because I think that auth
logic was/is flawed.  But attached is a version that I think will drop in.

IMHO, auth should have a definite structure.  It should not be something
where this and that gets tried until something happens to work.  And in the
case of registration, you could type an existing user name and password and
get in.  And that is not acceptable on a site that deals with credit cards,
or business presentation, or a lot of things.  I don't agree with the way
that registration is implemented in PHPSlash because it could be used on a
business site and someone could fairly easily do something to defame the
business by finding a loophole in the auth logic.

Concerning oohforms.inc I once made a similar comment, because it produces
alot of warnings with the latest PHP releases! It's old code and
implemented at times when obviously weren't so many warning messages
thrown out by PHP itself.

The only way to avoid this is to reimplement or improove oohforms! Another
way, which I currently use is to temporally set the error handling to a
level where error notices are simply disabled and switch back to the
original state if the oohforms access is finished.

You should use error_reporting(E_ERROR), since you had warnings.
See the manual!

RE: [Phplib-users] How to validate a oohform with js ?

hmm the validation works

but i have another problem :(

Warning: Variable passed to reset() is not an array or object in =
/var/www/html/php/of_text.inc on line 73

Warning: Variable passed to each() is not an array or object in =
/var/www/html/php/of_text.inc on line 74

this happens when i enter a javascript Name if i make no javascript =
validation everything works fine.
i tested it with "phplib-0.74.20021008.patches" and the version 7.4 =
only the line number differs


Warning: Variable passed to reset() is not an array or object in =
/var/www/html/php/of_text.inc on line 67

Warning: Variable passed to each() is not an array or object in =
/var/www/html/php/of_text.inc on line 68

with version 7.4=20

it=B4s these two lines=20
    reset($ndx_array);
    while (list($k, $n) =3D each($ndx_array)) {

any suggestions why this happens ?

is it possible that i use javascript validation with template=B4s ?

Re: [Phplib-users] Patch to page.inc

Hi, the following removes even doubled ampersands following the parameter
test and wipes it and its value away, leaving the rest of the string
untouched:

 ---snip---

  ***script start***

   <?php
     $a='url?test=testen&&test2=test2en&';
     echo "Rewrote:".ereg_replace("([?&])test=[^&]*&*", "\\1",$a)."\n";
   ?>

  ***script end***


  ***script output start***

   X-Powered-By: PHP/4.1.1
   Content-type: text/html

   Rewrote:url?test2=test2en&

  ***script output end***


 ---snip---
