Hi, folks,
good morning !
Since I'm a newbie with respect of sessions & cookies
I'm quite lost here getting always a warning when
calling session_start();
I developed and tested some php code using a session
to pass some values betwen different scripts on my
local machine. All went O.K.
But when I transferred the code to my provider's
server where my website is hosted, I constantly get
this warning when calling session_start():
Warning: session_start() [function.session-start]:
Cannot send session cache limiter - headers already
sent (output started at /...../sess.php:3) in
/...../sess.php on line 5
In line 5 is session_start();
I dotted-out the path prefices in this warning.
Lines 1-5 of my script "sess.php" are as follows:
1 <!-- ---- PHP CODE ------------------------- ->
2
3 <?php
4
5 session_start ();
In my browser (firefox) I've enabled cookies.
There were some differences between my local machine
and my provider's server in respect to session related
PHP flags/variables. I adapted those by adding
following lines in .htaccess on the webserver:
php_flag session.bug_compat_42 off # Was On
php_value session.bug_compat_42 off # Was On
php_flag session.cookie_httponly on # Was off
php_value session.cookie_httponly on # Was off
php_flag session.use_only_cookies On # Was off
php_value session.use_only_cookies On # Was off
Can anybody give me some hints for resolving this
issue and/or pointers where to dig further ?!?
Thanks in advance !

first - this is probably your culprit:
don't output empty lines before you do anything (just a general good practice)
also i'd turn on output buffering.

Whow! This did the trick !
Warning vanished when I changed beginning of
script to:
1 <?php session_start ();
2
I wasn't aware that the HTML comment and the
following empty line are in fact written to
output. But that's clear now :-)
So I suppose my local PHP setup supressed this
warning or is more compliant ...
> also i'd turn on output buffering.
Since it worked without warning at 1st try,
I haven't changed output buffering (yet).
Mike, many thanks for Your PROMPT and HELPFUL
answer! Have a nice day!

session_start (); should be before everything...first thing in the page.

Dear List -
Thanks to all for your EXCELLENT comments. I definitly agree that goto
is a command to be avoided at all costs. In this case, I could not
figure out how to acheive the desired result without the goto. So....
being a newbie, I humbly request that you show [and at the same time
teach] me how to rewrite the code to eleiminate the goto.
Additionally, would you please do the same for the code I list below.
This code runs perfectly.
==============
This is the form:
<form action="srchrhsptl2.php" method="post">
<center>Site: <input type="text" name="Site" value="AA" />
Record Number: <input type="text" name="MedRec" />
First Name: <input type="text" name="Fname" />
Last Name: <input type="text" name="Lname" /><br /><br />
Phone: <input type="text" name="Phone" />
Height: <input type="decimal" name="Height" /></input><br /><br />
Male<input type="radio" name="Sex" value = "0"></input>
Female<input type="radio" name="Sex" value = "1"></input><br /><br /><br />
<input type="submit" /><br /><br />
<input type="reset" value = "Clear Form" /></center>
</form>
Not sure if you can change the values for the Sex field to 'Male' &
'Female' respectively, but it would simplify the following example.
Here is my rendition of how I would do it.
<?php
...
$query = "select * from Intake3 where 1 ";
$allowed_fields = array('Site', 'MedRe', 'Fname', 'Lname',
'Phone', 'Sex', 'Height');
# deal with the special case first
# Normally you do not want to modify the _POST/_GET/_REQUEST array, but
# in this case, it is used as an quick example of how to get the data
# passed along. if you can change the field values to Male/Female you
# could remove the following section and have just the foreach() loop.
if ( ! empty($_POST['Sex']) )
{
if ( $_POST['Sex'] === '1' )
$_POST['Sex'] = 'Female';
else
$_POST['Sex'] = 'Male';
}
# Now deal with the rest...
foreach ( $allowed_fields AS $field )
{
if ( ! empty( $_POST[$field] ) )
{
$value = mysql_real_escape_string( $_POST[$field] );
$query .= " AND `{$field}` = '{$value}' ";
}
}
in the end, you will end up with a nicely formatted SQL query to execute.
I would suggest cleaning up the output code some and use *_assoc()
instead of the *_array() function call. It gives you back the array
version of the output. This way instead of calling $row[0], $row[...]
you would call $row['Fname'] or $row['Lname'] instead.
Get rid of all those commented out sections and you will have a good
script to play with.
Let us know what comes of it...
==============
THANK YOU EVER SO MUCH FOR YOUR HELP.
Ethan

Thanks for that. Things were getting too complicated because I had 2
significantly different features in 1 class. Now I've got 2 interfaces
(TaskInterface and TaskControllerInterface), things make more sense to
me.

Is this the only way to access the magic __set from the parent class:
public function __set($columnName, $value)
{
if ($value !== $this->$columnName) {
parent::__set($columnName, $value);
}
}
I would have liked to work this way:
public function __set($columnName, $value)
{
if ($value !== $this->$columnName) {
parent::$columnName = $value;
}
}
And another question.
There is a self, a static and a parent
Why is it only $this and not a $parent too?
--- End Message ---
--- Begin Message ---
Hello,
$this only calls variables inside of a method. In your function, you are
calling a variable that was defined inside of your function called
$columnName. You should past the whole class. Not just the methods.
"The pseudo-variable $this is available when a method is called from within
an object context. $this is a reference to the calling object (usually the
object to which the method belongs, but possibly another object, if the
method is called statically from the context of a secondary object). " taken
from http://www.php.net/manual/en/language.oop5.basic.php
The parent keyword indicates that this is an extended class. You are
referring back to the master class.
Ravi.

Hello,
Can someone recommend a web MP3 player? I need the following options:
1) Location and Duration of mp3 display (seconds)
2) The ability to pass a start and end parameter and play a part of
the song
3) Loop parameter
4) Call to the player to grab the mp3 Location and set it to a field
so i can insert it via PHP to mySQL
5) Work is most popular browsers
Free would be nice but I am will to pay a bit if it offers everything
I need.
Any suggestions would be appreciated.

You've missed a crucial part of php; its not a client-side language, its all
run on the server. So you can't have a music player built in it running in a
web browser. For that you need something like flash or java.
There is a way potentially with html5, but not all support the <audio> tag
(internet explorer for example) and not all support the same codecs.
Thanks,
Ash

For playing MP3s (I have an alert system running in our call centre),
I use SoundManager2. It's a JS library which allows me to play mp3
files. They are controlled by an AJAX orientated request to PHP which
gathers the data and determines what alert needs to be played.
Was first running on IE6.

Not trying to sound rude or prickish... but is it your ISP or connection
to the intertubes? Or could it be an issue with your computer?
I've never had any problems posting, or retrieving mail from this list,
so I can't say/speak to a related issue.

Hello Gary,
Please research the difference between a single quote and a double quote.
Also, you can use the operator .=(dot + equal) in this manner:
if(!empty($_POST['fname'])) {
$msg .= "$lname\n";
} else if(!empty($_POST['lname'])) {
$msg .= "$lname\n";
}
