[Get index of array?]

hi,

 

use array_search, not in_array. array_search gives you the key (index) of the search pattern if it exists.

 

hope this will help.

 

 

[More than one button into one form]

[!--quoteo(post=356884:date=Mar 21 2006, 08:44 AM:name=firedrop)--][div class=\'quotetop\']QUOTE(firedrop @ Mar 21 2006, 08:44 AM) [snapback]356884[/snapback][/div][div class=\'quotemain\'][!--quotec--]
I have another question. when I got for example in a form a submit button I usually use the action in the form and thats in the HTML to allow it to go for the page that I would like.

I am wondering what if I have two buttons that they do two different actions. How I can handle this.

Hi,

don't use any action or use action = "<?echo $PHP_SELF?>" to call the same script. Then use an if ... elseif ... else - construct like

[code]

<?php

# Submit - Button #1
if (isset($_POST[submit_button_1]) {

   # action for submit - button #1

} // if

# Submit -  Button #2
elseif (isset($_POST[submit_button_2]) {

   # action for submit - button #2

} // if

# Standard - form
else {

   ?>

   <form method = "POST">
  
        .......

   </form>

   <?

} // else

?>

[/code]

# First step: Receiving your 5 last data

$query = "SELECT * FROM ... WHERE ... ORDER BY date DESC LIMIT 5";

$result = mysql_query($query, $databaseconnection);

while (@$row = mysql_fetch_array($result)) {

        # Do something with your received data

} // while


# Second step: What is the highest date in db?

$query = "SELECT MAX(date) AS max  FROM ... ";

$result = mysql_query($query, $databaseconnection);

[Unexpected '{' in Session Code!!]

yeah both worked .....

but now further errors relating to the session at the beginning....

Warning: session_start(): open(/tmp\sess_99a3b92d86e67afe762f29c6b156dfe4, O_RDWR) failed: No such file or directory (2) in C:\Program Files\Apache Group\Apache2\htdocs\dvdreviewer\LoginTest.php on line 1

then it displays it correctly ... saying 'Please Sign in'

then further errors....

Warning: Unknown(): open(/tmp\sess_99a3b92d86e67afe762f29c6b156dfe4, O_RDWR) failed: No such file or directory (2) in Unknown on line 0

Hi from Germany,

the first error message seems to be php.ini - config problem. you're using windows, the standard php.ini (\tmp) for session dir is no usable under windows. you have do create a directory and add this to your php.ini like

session.save_path = C:\Program Files\Apache Group\Apache2\sessions

The second and third error message due to the first error message, this was an output and session_start() must be set before any screen output.

Hope it will work,

I want to remember the users username and password

i've been told to look into sessions, from what i've learned would I be right in simply doing the following...

$_SESSION['loginname'] = $_POST['loginname'];

$_SESSION['password'] = $_POST['password'];

and then just

session_start();

at the beginning of each page where it is needed?

Then call $_SESSION['loginname'] when I need to access the database?

then when they log out simply....

$_SESSION['loginname'] = '';

$_SESSION['password'] = '';

i'm NEW!!!!!!!! SORRY!!!!

Thanks

Hi,

session_start() must be set before any output of your script. For identifying a logged user just ask

session_start();
if (isset($_SESSION['loginname']) {

..... code .....

} // if

For logout I suggest a unset($_SESSION).

how will you set your sql query in such a way that i will just show the
last 5 data by date.
lets say, today is march 7, it will just show the 5 data from march 7 onwards
and once the date has expired or when there is no more data to show it
will print a comment saying "no current events"

need help.
thanks!
