PHP - *simple $_post Problem

Hi,
I just wanted to know how posting works?.

i know how to sort of post and get info..
What i want to know is: is it possible to post something from a folder structure like so:

http://wwww.xxx.com/postfolder1/postfolder2/postfolder3/postfolder4/form.php  // this is the file that posts.. lets say! a username.

to

http://www.xxx.com/notpostfolder1/notpostfolder2/notpostfolder3/notpostfolder4/index.php // the file that gets the post : The username..

or is a php database the only answer to transfer the information?

i also just discovered that in cookies if i ad path/ the cookie is valid through out the site.. is ther something like this for Post and get??

hello i have a script and i keep getting an error
on php4 i dont get that error
only on php5

<?php
session_start();
error_reporting(E_ALL);
ini_set('display_errors',1);
function query_str($params) {
        $str = '';
                foreach ($params as $key => $value) {
                        $str .= (strlen($str) < 1) ? '' : '&';
                        $str .= $key . '=' . rawurlencode($value);
                }
                 return ($str);
}

if($_GET['id']=='1'){
                $query=parse_str($_POST);
                query_str($query);
                $username=rtrim($username);
                $password=rtrim($password);
                // .... continue
echo $username.':'.$password.chr(10);
}


Code: [Select]

<form  name="Form_Auth" action="do.php?id=1" method="post" target="_top">
<input name="username" id="txt" value="Nome utente" class="nomeutente">

<input name="bottone" type="submit" class="bottone rf" value="Invia" alt="accedi">
</form>

Hi, I am using POST to send the id of a row in a MySQL database, this id should then be used to delete the row from MySQL, this all works fine when I use GET, but as soon as i try and use POST (for security reasons) it deletes another row.
Here is the code ($_POST):
Code: [Select]
<?php

$member = $logged['username'];
//IFMESSAGES THEN SAY OTHERWISE SAY NO 

$seemessages = mysql_query("SELECT * FROM `rmail` WHERE `to` = '$member' && `status` = 'unread'");
$howmanymessages = mysql_num_rows($seemessages);

$seereadmessages = mysql_query("SELECT * FROM `rmail` WHERE `status` = 'read' && `to` = '$member'");
$howmanyreadmessages = mysql_num_rows($seereadmessages);  
$totalmessages = $howmanyreadmessages + $howmanymessages;
//MENU FOR USING EMAIL VIEWED ON ALL SECTIONS OF R-MAIL
echo'<div id="emailmenu"><a href="rmail.php">Home</a>|<a href="rmail.php?inbox">Inbox('.$howmanymessages.'/'.$totalmessages.')</a>|<a href="rmail.php?compose">Compose</a>| </div><br/>';

if(isset($_POST['delete'])){
//DELETE MESSAGE
$id = $_POST['delete'];
echo $id;
$newvalue = mysql_query("SELECT * FROM data");
$newvalue = mysql_fetch_array($newvalue);
$newvalue = $newvalue['rmailsent'];
$newvalue = $newvalue-1;
mysql_query("UPDATE data SET rmailsent = '$newvalue'");
mysql_query("DELETE FROM rmail WHERE `id` = '$id'");
echo "Message has been deleted!";
}
else if(isset($_GET['inbox'])){
$username = $logged['username'];
//DISPLAY EMAILS FOR USER
//WHEN DISPLAYING DISPLAY LINK WITH THE ID TO VIEW THE SPECIFIC MESSAGE
$getemail = mysql_query("SELECT * from rmail WHERE `to` = '$username' ORDER BY `id` DESC");

echo'
<table border="1">
<tr>
<td> <font size="5">Check</font> </td>
<td> <font size="5">Status</font></td>
<td><font size="5">From</font></td>
<td width="500"><font size="5">Subject</font></td>
<td><font size="5">Date Sent</font></td>
<td><font size="5">Time Sent</font></td>
<td><font size="5">Action</font></td>
</tr>
';
while($email = mysql_fetch_array($getemail)){
$id = $email['id'];
if($email['status'] == "unread"){
echo "<tr bgcolor='#666666'>";
}else{
echo "<tr>";
}
echo '<td><input type="checkbox" name="'.$email['id'].'checked" class="check"></td>';
echo '<td>';
if($email['status'] == "unread"){
echo '<center><img src="/webimages/unread.gif" alt="Message Unread" width="30" height="25"></center>';
}else if($email['status'] == "read"){
echo '<center><img src="/webimages/read.gif" alt="Message Read" width="30" height="25"><center>';
}
echo '</td>';
echo '<td>'.$email['from'].'</td>';
echo '<td><a href="rmail.php?viewmail&id='.$email['id'].'">'.$email['subject'].'</a></td>';
echo '<td>'.$email['date'].'</td>';
echo '<td>'.$email['time'].'</td>';
echo '<td><form action="rmail.php" method="post">
<input type="hidden" value="'.$email['id'].'" name="delete"><input type="image" src="/webimages/delete.png" onclick="return confirm(\'Are you sure you want to Delete?Click Ok to proceed and Delete or Cancel if you do not want to delete!\');"><a href="viewmembers.php?user='.$email['from'].'"><img src="/webimages/eye3.gif" border="0" height="25" width="30"></a></td>';

echo "</font></tr>";
}
echo "</table>";
}

</html>
Here is the code with $_GET (this works but $_POST doesnt):
Code: [Select]
<?php

$member = $logged['username'];
//IFMESSAGES THEN SAY OTHERWISE SAY NO 

$seemessages = mysql_query("SELECT * FROM `rmail` WHERE `to` = '$member' && `status` = 'unread'");
$howmanymessages = mysql_num_rows($seemessages);

$seereadmessages = mysql_query("SELECT * FROM `rmail` WHERE `status` = 'read' && `to` = '$member'");
$howmanyreadmessages = mysql_num_rows($seereadmessages);  
$totalmessages = $howmanyreadmessages + $howmanymessages;
//MENU FOR USING EMAIL VIEWED ON ALL SECTIONS OF R-MAIL
echo'<div id="emailmenu"><a href="rmail.php">Home</a>|<a href="rmail.php?inbox">Inbox('.$howmanymessages.'/'.$totalmessages.')</a>|<a href="rmail.php?compose">Compose</a>| </div><br/>';

if(isset($_GET['delete'])){
//DELETE MESSAGE
$id = $_GET['delete'];
echo $id;
$newvalue = mysql_query("SELECT * FROM data");
$newvalue = mysql_fetch_array($newvalue);
$newvalue = $newvalue['rmailsent'];
$newvalue = $newvalue-1;
mysql_query("UPDATE data SET rmailsent = '$newvalue'");
mysql_query("DELETE FROM rmail WHERE `id` = '$id'");
echo "Message has been deleted!";
}
else if(isset($_GET['inbox'])){
$username = $logged['username'];
//DISPLAY EMAILS FOR USER

Any Ideas?

Hi there I'm trying to make this form submit...but alas, is to no avail .... i have two forms on top of each other one of them is:

Code: [Select]
<form name="entries_form" method="post" action="index.php">
        <table>
    <tr>
<th><label>Date</label></th>
<th><label>From</label></th>
<th><label>To</label></th>
<th><label>Break</label></th>
<th><label>Hours</label></th>
<th><label>Required Hours</label></th>
<th><label>Notes</label></th>
    </tr>
    <tr>
<td>
   
    <input name="Date" type="text" id="Date" />
</td>
<td>
   
<input name="From" type="text" id="From" />
</td>
<td>
    <input name="To" type="text" id="To" />
</td>
<td>
   
    <input name="Break" type="text" id="Break" />
</td>
<td>
   
    <input name="Hours" type="text" id="Hours" />
</td>
<td>
   
    <input name="Rqrd_hrs" type="text" id="Rqrd_hrs" />
</td>
<td>
   
    <input name="Notes" type="text" id="Notes" />
</td>
<td>
    <input type="submit" name="Save" value="Save" id="Save" style="background-color:#7A70A4;" />
</td>
    </tr>
</table>
    </form>
to post i'm using this code (to much over the top maybe):
Code: [Select]
<?php

$session = new Session();
$u_id = $session->get('id'); //to get the user id from session

 if(isset($_POST['submit']) == 'Save'){//form's button  name is Save
$entry->user_id = $user_id = $u_id;
        $entry->date = $date = trim(strtolower($_POST['Date']));
        $entry->start_time = $start_time = trim(strtolower($_POST['From']));
        $entry->end_time   = $end_time   = trim(strtolower($_POST['To']));
$entry->breaks      = $break   = trim(strtolower($_POST['Break']));
$entry->total_hours   = $total_hours   = trim(strtolower($_POST['Hours']));
$entry->reqd_hours   = $required_hours   = trim(strtolower($_POST['Rqrd_hrs']));
$entry->notes   = $notes   = trim(strtolower($_POST['Notes'])); 
   
        $entry->add_entry();
    }else die("Not Posted");
    ?>
the add entry() function does the following:
Code: [Select]
public function add_entry(){
    global $database;
$sql = "INSERT INTO sheetentries (";
$sql .= "user_id, date, start_time, end_time, break, required_hours, total_hours, notes";
$sql .= ") VALUES ('";
$sql .= $this->user_id ."', '";
$sql .= $this->date ."', '";
$sql .= $this->start_time ."', '";
$sql .= $this->end_time ."', '";
$sql .= $this->breaks ."', '";
$sql .= $this->reqd_hours ."', '";
$sql .= $this->total_hours ."', '";
$sql .= $this->notes ."')";
    $database->query($sql);
    }
the user_id or $u_id brought from the session when the user loggs in:
Code: [Select]
$u_id = $session->get('id');
anyway, whenever i try submitting the form nothing happens, what am i missing,,, thanks in advance

I'm making a script for editing lines in a text file.

PHP code form form script:

$n = 0;
$bestand = "../test.txt"; 
$gegevens = file($bestand);

//count lines titel.txt
$lines = count(file($bestand));

while($n < $lines) {
$items = explode("|", $gegevens[$n]);
$titel = $items[0]; 
$beschrijving = $items[1];
$n=$n+1;

echo "<tr>
<td><input type=\"text\" class=\"edit\" name=\"titel[".$n."]\" value=\" ".$titel." \" /></td>
<td><textarea name=\"beschrijving[".$n."]\">".$beschrijving."</textarea></td>
  </tr>";
}


Code of processing script

<?php
$n = 1;

$bestand = "../test.txt";
$lines = count(file($bestand));

while($n < $lines){

//Set variables
$titel = $_POST['titel[$n]'];

//Replace 'Enter' for '<br />'
$_POST['beschrijving[$n]'] = preg_replace ("#\r?\n#", '<br />', $_POST['beschrijving[$n]']);
$beschrijving = $_POST['beschrijving[$n]'];

//Write $titel
$handle = fopen($bestand, "a");
fwrite($handle, "".$titel."|");
fclose($handle);

//Write $beschrijving
$handle = fopen($bestand, "a+");
fwrite($handle, "".$beschrijving." ");
fclose($handle);

$n=$n+1;
}
?>


De form scripts works fine, no problems. But the processing script give me the next notices:

Code: [Select]
Notice: Undefined index: titel[$n] in /var/www/NellekeTekent/cms/edit.php on line 10 Notice: Undefined index: beschrijving[$n] in /var/www/NellekeTekent/cms/edit.php on line 13 Notice: Undefined index: titel[$n] in /var/www/NellekeTekent/cms/edit.php on line 10 Notice: Undefined index: titel[$n] in /var/www/NellekeTekent/cms/edit.php on line 10 Notice: Undefined index: titel[$n] in /var/www/NellekeTekent/cms/edit.php on line 10
I gues the problem is '$n' when setting $titel and $beschrijving.
But I don't know how to solve it.
Can you help me?
