Hi
This is my first class and it does not work, i do a return
$this->responseArray; with the public function getResult() method, but get
nothing. Can someone please help me.
Thsi is how i create the object
$number = new Smsgate($cell_numbers, $message, "27823361602", "27");
$result = $number->getResult();
Here is the code:
<?php

*/

$this->result = "";
// loop through numbers and check for errors
foreach ($this->number as $this->val) {
$this->position = strpos($this->val , $this->tofind);
// number correct
if ($this->position === 0) {
echo "is integer <br/>";
if ($this->result != "") {
$this->result .= ",";
}
// create comma seperated numbers to send as bulk in
sendSMS method
$this->result .= $this->val; //infobip multiple
recipients must be seperated by comma
// create an array to use with responseStringExplode in
sendSMS method
$this->cellarray[] = $this->val;
echo "Result is " . $this->result . "<br>";
} else {

$this->errorResult[] = $this->val;
}
} //end foreach
$this->sendSMS();
} else {
$this->result = "Not ok";

Not really, what if someone else decided they wanted to throw in their
own form field values in the hope of breaking your system? It's much
better to be specifically looking for certain form fields and certain
field values/ranges. For example, if you had some fields that would
filter something by cost, you might have two form fields named 'max' and
'min' which would be ranges for the cost. You should check that these
fields only contain numbers for example before processing them. Any data
coming from the client-side is untrustworthy and should be regarded as
tainted until you can prove otherwise.
Thanks,

There are a couple of ways that you can do this:
1. Store the post values in the $_SESSION variable then echo them back to the
screen. Be careful with this as it can lead to XSS. Strip html, etc
2. Send the post values back to the form as part of the query sting. This
solution is limited to the size of the query string (2k). Be careful with XSS
Another solution is to use a framework to handle the post back values. One such
framework is called Raxan. Here's an example of what it can do:

Subject: [PHP] processing html forms and keeping the values
Hi there,
I am trying to redirect a user back to a html form if a validation failes. The
form shoult then hold all entered values. So far I did this over $_GET, but
there is a 100 Character limitation. How could I do this while keeping all
characters?
Thank you for any hint,

Hello Raymond,
thank you for your hint. I will go with sessions. Thanx for the note
regarding XSS.

This is not so easy. I am doing some checking with php on the values and
if one failes php returns via GET to the form with the help of header
location:
$parameter = "&demo=this";
HEADER("Location:/test.html?error=1".$parameter);
exit;
I would need to change way to many things in order to simply change to
post.
Isn't there another way?
This is what I normally do with larger forms:
1. create the form as a function: form()
2. submit the form to the same page
3. test relevant input and if the fail print form()
Example:
function form() {
print '
<form action="'.$_SERVER['PHP_SELF'].'" method="post">
<input type="text" name="email" value="'.$_POST['email'].'">
<input type="submit" name="submit" value="send form">
</form>';
}
if($_POST['submit']) {
// test email is entered
if(!$_POST['email']) {
print "error: you must enter an e-mail address";
form();
}
else {
// do stuff from here...
}
}
else
form();
With a 50 field form this is a nice approach for me :-)

check these options
*-pass arg, -passin arg*
the PKCS#12 file (i.e. input file) password source. For more information
about the format of *arg* see the *PASS PHRASE ARGUMENTS* section in *
openssl*(1) <http://www.openssl.org/docs/apps/openssl.html#>.
*-passout arg*
pass phrase source to encrypt any outputed private keys with. For more
information about the format of *arg* see the *PASS PHRASE ARGUMENTS*section in
*openssl*(1) <http://www.openssl.org/docs/apps/openssl.html#>.
I believe you can ask user their password on previous page and utilize the
'pass' option and it won't ask for a password again

After a long delay, I've finally got mail working. I had decided to
move on in the book that I'm working through (Head First PHP & MySQL)
but doubled back to address the mail issue again. This is how I
finally got it to work:
1. Switched to XAMPP for linux rather than using my existing versions
of mysql, php and apache.
2. Uninstalled Postfix and reinstalled Sendmail. Then I followed the
instructions here:
http://dbaron.org/linux/sendmail
I can't vouch that the method described at that link is completely
safe and secure, but it worked for me and was very easy. I've spent
many hours and days trying to get this to work so am very relieved.
My only complaint is that there is quite a long delay after submitting
report.html (from Ch. 1) while it says 'waiting for localhost...'. It
can take up to 20 seconds or so before sending and giving
confirmation.
Thanks for all your help.

It looks like using XAMPP wasn't strictly necessary. I tried running
this example again using my previous versions of mysql and apache and
it worked fine. So the key is to configure Sendmail as described at
the URL I gave.

Hi,
I have been trying for the last couple of hours to determine the
encoding of a text file (.txt in windowz).
I have this code:
$contents = file_get_contents($config['txt_dir'] . $file);
$encoding = mb_detect_encoding($contents,
"UTF-8,ISO-8859-1,WINDOWS-1252"); //,Windows-1255
echo "||encoding:".$encoding."||";
if ($encoding == 'UTF-8')
{
$utfcontents = $contents;
}
else if ($encoding == 'ISO-8859-1')
{
$utfcontents = utf8_encode($contents);
}
var_dump($utfcontents);
The $encoding is ISO-8859-1, the text file contains Hebrew characters, then
I'm converting it to utf8.
The above code is outputing gibbrish, it seems that it has converted it in
some way but not in the
proper way that it should have converted it.
My page is UTF-8 encoded, without BOM, I send UTF-8 headers to the browser
and HTML content
encoding meta tag as well.
I have no idea what I am doing wrong.
I would highly appreciate it if someone could point me to the right
direction.
Thanks in Advance,
Nitsan
