Combine variable to make new variable

[themonkey40]

Ok I am getting a little lost, but really appreciate everyone's help. Here is some code that may clarify things:

updateSpec($_POST['id1'],$_POST['desc1'],$_POST['value1'],$_POST['num1'])
updateSpec($_POST['id2'],$_POST['desc2'],$_POST['value2'],$_POST['num2'])
updateSpec($_POST['id3'],$_POST['desc3'],$_POST['value3'],$_POST['num3']) 

This function updates a spec block for a product. Each product may have a different number of specs, so I am using

$count = mysql_num_rows 

in a query to get the number of rows, and then want to execute a loop $count times.

I could just cut and paste the code 50 times and use (if(isset()), but that doesn't seem the most efficient may.

I know I need to run some kind of loop, but not sure how to code exactly. Hope this clarifies and any help is greatly appreciated.

Where you are creating your form...

 while($spec=mysql_fetch_array($sql)) { ?>
        <tr>
            <td width="10%" valign="top"><input type="text" size="2" value="<?php echo $spec['num']; ?>" name="num[]"></td>
            <td width="30%" valign="top"><input type="text" size="30" value="<?php echo $spec['descriptor']; ?>" name="desc[]"></td>
            <td width="30%" valign="top"><textarea name="value[]"><?php echo $spec['value']; ?></textarea></td>
            <input type="hidden" value="<?php echo $spec['id']; ?>" name="id[]">
            <td width="30%"></td>
        </tr>
<?php } ?>

criterion9 I made that change in my HTML form, how to I get the php process page to update all the rows using the function?

[criterion9]

You mean the code that was already posted?

if(isset($_POST['id']) && is_array($_POST['id'])){
    $i = 0;
    foreach($_POST['id'] as $id) {
    updateSpec($_POST['id'][$i],$_POST['desc'][$i],$_POST['value'][$i],$_POST['num'][$i]);
        $i++;
    }
} 

Only minor modifications to include the other _POST vars were made.

Oh my gosh, that worked as is simply amazing code. So stoked thanks for everyone's help. webdeveloper.com rocks.

Special thanks to criterion9 for staying with me through my stupidness.

Lol. Sometimes it takes a couple looks at someone else's code before it sinks in how simplistic it can be. You might take a look at the array page on php.net to see if that helps a bit with the amazing power of arrays.

I have the variable $id and I want to make it $id1, $id2, $id3... How can I code it so that it will make $id1?
