save data from multiple input form

[snipe42]

Hi, excuse me. Im new here, but i really need help. I can't find any idea to solve this.

so,i want to save data that i input to the table.
The table itself made from input form, consist row and columns as i order before.
here is code for table input.php

<form id="form1" name="form1" method="post" action="result.php">

<tr>
<td width="30%" align="left" valign="top">Input the number of columns     :<td height="37" align="left" valign="top"><input type="text" name="colums" value="" /></td>
</tr>
<tr>
<td align="left" valign="top">Input the number of rows :</td>
<td width="70%" align="left" valign="top"><input type="text" name="rows" value="" /></td>
</tr>
<tr>
<td align="left" valign="top">&nbsp;</td>
<td align="left" valign="top"><input type="submit" name="button" id="button" value="Submit" /></td>
</tr>
</table>
</form> 

and the result.php generate the table. each cell is input form.

<?php
$columns = $_POST['columns'];
$rows = $_POST['rows'];

echo "<form method='post' action='process.php'>";
echo "<table>";

//made the columns
for ($i= 0; $i <=$baris-1; $i++){

//and the rows
echo "<tr>";
for ($j = 0; $j <= $kolom-1; $j++) {

//here is the input form, and each of data inputed here that i want to save it.
$sum = array('[$i][$j]');
    echo "<td> </td>
        <td><input size='5' type='text' name='data".$sum."' /></td>
    ";

}
}

echo "</tr>";
echo "<tr><td></td><td><input type='submit' name='submit' values='Submit' /></td></tr>";
//im not sure here in value='$sum'
echo "<tr><td></td><td><input type='hidden' name='banyak' value='$sum' /></td></tr>";
echo "</table>";
echo "</form>";

// here,which one should i $_GET[''] ?

?>

and, in process.php should show the average the all data, or any other math formula.
i use the single input data in process.php,and its totally wrong :s

If you are new and in no great hurry then I recommend you ditch this code and learn instead to do it in ajax.

So much nicer for the end user to use interactive websites that impliment ajax.

actually, im in great hurry.
the problem is, it wont save data input in form.
even i made it as 2d array.

could you give suggestion to ajax tutorial for my problem ?

Not sure if this is your main problem, but you probably want the "row" loop to be the outer loop:

$columns = (int) $_POST['columns'];
$rows = (int) $_POST['rows']; 
for($row = 0; $row < $rows; $row++) {
  echo "<tr>";
  for($col = 0; $col < $columns; $col++) {
    echo "<td>".($row + $col)."</td>"
  }
  echo "</tr>\n";
}

no,it's not.
the rows and columns is okay. the problem is,how can i save the data that I input to the form inside the rows and columns,and i could use it later.

[NogDog]

sessions?
database?

[snipe42]

resolved. sorry, i made this so hardly to understand with foreign language in variable.

so, for the input.php there's nothing to change.
in result.php

$kolom is $columns
$baris is $rows

then, change this line

//here is the input form, and each of data inputed here that i want to save it. 
$sum = array('[$i][$j]'); 
    echo "<td> </td> 
        <td><input size='5' type='text' name='data".$sum."' /></td> 
    "; 

and should be like this

//here is the input form, and each of data inputed here that i want to save it. 
$data = array("[$i][$j]");

    echo "<td> </td>
        <td><input size='5' type='text' name='data[{$i}][{$j}]' value'foo'/> "; </td> 

and doesn't need the hidden value as show in the line

echo "<tr><td></td><td><input type='hidden' name='banyak' value='$sum' /></td></tr>"; 

and to print data inside array, i use

$array = ($_POST['data'])

which mean save 2d array to a new var, then could be use in future.
