Php $_post

[clemton]

I have this code:

$g = 1;
        echo $checkListCount;
        while($g <= $checkListCount){
 
            $fg = 'sdl'.$g;
 
            echo $_POST[$fg];
 
            ++$g;           
       }
 

The question is, why won't it work?
It doesn't give out any error but it doesn't do what it should?
And a there really are values for $_POST['sdl1'],$_POST['sdl2'],$_POST['sdl3']...

I think the problem's with this:

echo $_POST[$fg];

Any help will be very much appreciated.

What does happen? What doesn't happen? What is *supposed* to happen?
No errors?

Do a print_r() on $_POST and see what's actually in there.

Hi.

The $_POST super-global gets it's values from HTML forms (usually).
So, how does the form that supplies the data for you script look like?

What I want to happen sir is to make the value for $_POST[' '] dynamic.

For example:

If i have such data from a form as $_POST['a1'], $_POST['a2'], $_POST['a3'], so on..

This:

 $g = 1;
         echo $checkListCount;
         while($g <= $checkListCount){
 
             $fg = 'a'.$g;
 
             echo $_POST[$fg];
 
             ++$g;           
         }
 

will output all the values of $_POST['a1'], $_POST['a2'], $_POST['a3'], so on..

thanks for the reply

The form is this way:

<form action="'.$_SERVER['PHP_SELF'].'" method="post">
$c=1;
 while($row = mysql_fetch_array($list)){
 
                                        $at = 'syear'.$c;
                                        $bt = 'semester'.$c;
                                        $ct = 'colcov'.$c;
                                        $dt = 'col2bcov'.$c;
                                        $et = 'sdl'.$c;
 
echo '<table align="center" width="500" cellpadding="0" cellspacing="0">
<tr  style="background-color:#dddddd;">
<td align="center" class="style9"><input type="text" name="'.$at.'" value='. $row['syear'].'></td>
<td align="center" class="style9"><input type="text" name="'.$bt.'" value='. $row['semester'].'></td>
<td align="center" class="style9"><input type="text" name="'.$ct.'" value='. $row['colcov'].'></td>
<td align="center" class="style9"><input type="text" name="'.$dt.'" value='. $row['col2bcov'].'></td>
<td align="center" class="style9"><input type="text" name="'.$et.'" value='. $row['sdl'].'></td>
</tr>
</table>';
 
} 
 
echo '<table align="center" width="500" cellpadding="0" cellspacing="0">
    <tr style="background-color:#333333;">
    <td align="right">&nbsp;</td>
    <td align="left"><input type="submit" name="submitEdit" value="Save"></td>
        <td align="right"><input type="reset" value="Reset"></td>
        </tr>

Heya, Clemton.

You're making this way too complicated. Name your inputs with '[]' at the end, and PHP will create an array inside of $_POST:

<input ... name="color[]" />
<input ... name="color[]" />
 

foreach( $_POST['color'] as $idx => $val ) ...
