gettting values of select options from form

i have a form that has a varied number of select options.

after the form is posted, it goes to a php file.

in the php file, in a while loop, i have a $count++

how do i get the value inside $Cm1 or $Cm2 or ... $Cm100


for ($a=0;$a<=100;$a++) {
// process
}

by doing something like

$var = $"Cm"."$count";

currently, this only has the value "Cm1"

and

$$var has the value of "$Cm1" ?


// echo "$Cm1 <p> "; // this works
// echo "$Cm2 <p>";

you could try:



That should loop through the $_POST array and display only the name and value of the variable that begins with "Cm".

I hope this is what you meant.

Have you created the selects as an array in your HTML form?

For example:


If you create the selects as an array in the form, you can access them as you would any other array in PHP.

For example:

for loop
{

echo "<select name=Cm"; echo "$count"; echo "><option>n</option> <option>y</option></select>";

echo "<select name=Cm"; echo "$count"; echo "><option>y</option></select>";

}

i need the value in the select object for processing.

is it good to make it an array ?

Arrays would be eaiser to use. Just use cm[] rather than a counter for the name. PHP Will automatically make them an array.
