for loop

I have a textfield:

<?php for($i = 1;$i <= $var;$i++){?>
<input type="text" name="option<?php echo $i;?>">
<?php } ?>

Therefore when the form is submitted the values are option1, option2, option3 etc. (up to $var size)

How can I can I then echo the value of those textfields when $i can range from 1 to anything. Thank you?

P.S. I tried the code below and it didnt work:

<?php
for($i = 1;$i <= $var;$i++){
echo "$option$i";
}
?>

Could do it this way ...

<?php
for($i = 1;$i <= $var;$i++){
$tempvar = "option$i";
echo $$tempvar;
}

Guess you could also store your values in an array

for($i = 1;$i <= $var;$i++){
echo "<input type=text name=option[]>";
}

and you will have

$option as an array afterwards which you can loop ...
(works for checkboxes, not sure for textinputs, but may try...)

I tried your first example however it didnt work. What could I be doing wrong?

I don't suppose you know of a definate sure fire hit.

why don't you make them an array? should be easier to handle.

<?php for($i = 1;$i <= $var;$i++){?>
<input type="text" name="option[]">
<?php } ?>

<?php
// replace $GET with $POST if necessary, depending on the form method used to submit.
for($i = 0;$i < count($GET['option']);$i++){
echo $GET['option'][$i]";
}
?>

thanks so much. I am still pretty new with PHP really and some things I can do easily (like navigation buttons, authentication etc) and other, little things stump me. I will have to buy a decent PHP book I think.

Thanks anyway...Happy Easter
