get data from dinamic table

Hi, i´m trying to get data from a html dinamic table that it´s created in the form html with this code:

 <style>
@import url(templates/form.css);
</style>

<?
session_start();
$repositorio=$_SESSION["archivo"];
$sec=$_SESSION["sec"];

echo "<table id='tablapaquetes' border = '1'> \n";
echo "<tr>";
echo "<td bgcolor='#FF0000'><strong> </strong></td>";
echo "<td align='center' bgcolor='#FF0000'><strong>Paquete</strong></td>";
echo "<td align='center' bgcolor='#FF0000'><strong>Seccion</strong></td>";
echo "<td align='center' bgcolor='#FF0000'><strong>Descripcion</strong></td>";
echo "<tr>";
$i=0;

$fichero='/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_gutsy_'.$repositorio.'_binary-i386_Packages';
$archivo = fopen ($fichero, "r"); 
 while (!feof ($archivo))
{
 	while($linea = fgets($archivo))
	{
		if (($linea[0] == 'P') && ($linea[1] == 'a')&& ($linea[2] == 'c'))
        	{ 
			$temp=substr ($linea, 9, 40); 
			$pack=trim($temp);			
                }
		if(($linea[0]=='S')&&($linea[1]=='e')&&($linea[2]=='c'))
		{
			if(($repositorio[0]=='m')&&($repositorio[1]=='a'))
                        {
                              $temp=substr ($linea, 9, 40);
			      $seccion=trim($temp);
                        }if(($repositorio[0]=='m')&&($repositorio[1]=='u'))
                        {
                              $temp=substr ($linea, 20, 40);
			      $seccion=trim($temp);
                        }if(($repositorio[0]=='u')&&($repositorio[1]=='n'))
                        {
                              $temp=substr ($linea, 18, 40);
			      $seccion=trim($temp);
                        }if(($repositorio[0]=='r')&&($repositorio[1]=='e'))
                        {
                              $temp=substr ($linea, 20, 40);
			      $seccion=trim($temp);
                        }
		}
                if (($linea[0] == 'D') && ($linea[1] == 'e')&& ($linea[2] == 's'))
        	{ 
			$temp=substr ($linea, 13, 150); 
			$desc=trim($temp);	
		if(($seccion[0]==$sec[0])&&($seccion[1]==$sec[1])&&($seccion[2]==$sec[2])&&($desc[0]!=''))
	         {
			echo "<td><INPUT type='checkbox' name='";
			echo "check'.$i.''></td>";
			echo "<td align='center' bgcolor='#CCCCCC'><strong>$pack</strong></td>";
				echo "<td align='center' bgcolor='#CCCCCC'><strong>$seccion</strong></td>";
echo "<td align='center' bgcolor='#CCCCCC'><strong>$desc</strong></td>";
				echo "</tr>";
				$i++;
			}
                 }
	}
}
echo $i;

echo "</table>";

session_start();
$_SESSION["i"] = $i;
?> 

<p align="center"><INPUT type="submit" name="boton1" value="Añadir a la distribución"></p>

This code just takes information from a txt file and put it into a table with a checkbox at the begining of every line.

I would like to take the information from the second column (named paquete) when submiting and put it into a new txt file.

Could be something like this?

<?php
session_start();
$contador=$_SESSION["i"];
echo $contador;
for($p=0;$p<$contador;$p++)
{
    $check=check.$p;
    if(( $_POST['$check'] == "on" ))
    {   
       echo $p;
    }
}
?>

Thanks a lot.

Hi, I can't understand where the problem is ?

<?php
session_start();
$contador=$_SESSION["i"];
echo $contador;
for($p=0;$p<$contador;$p++)
{
    $check=check.$p;
    if(( $_POST['$check'] == "on" ))
    {   
       echo $p;
    }
}
?>

Here is the problem, This code doesn´t work. I need to take the information(name) from the column next to the checkboxes selected and get it by the php code when submiting. But this code doesn´t even get me the checkboxes selected. How can i get that information?
Thans a lot

but why do you need sessions, you can know which boxes are checked through the POST array only!

sorry i doon´t know how to do it could you show me?
I use session just to get how many lines does the table have. and to get every checkbox, but that doesn´t work, and don´t know how to do it as you say.

Ok, for example, give all your checkboxes names starting with "check" and then loop through all posted data with names starting with "check" only, need a foreach loop with key and data and some PHP string function!

Cheers

Hi again, I still don find the way, could you have a look at this code and tell me what i doing wrong?
This is how i create the checkboxes in the html table:
echo "<td> <input type='checkbox' name='chk[]' value='$i'></td>";

and this is how i eval them in the php code after submitting:
foreach($_POST['chk'] as $value)
{
if($value=='on')
{
echo "checked";
}
}

Hi wachusfleish,

The value isn't going to be 'on' it will be '$i' or whatever that evaluates to.

Turn on Debug and see what is really in the $_POST array, that will help you write your PHP.

Thanks a lot greyhead and admin.
Debug helped me a lot. THANK YOU, without your help i would have still been block.
