[RESOLVED] Problem in sending form values through loop...

Mahmood_Akhtar

I'm facing a problem in sending and receiving the form values which has been established with a loop. Consider the line given below, which is running under a loop...

<input id="opt_<?=$opt?>" name="opt_<?=$opt?>" type="radio" value="<?=$optionrs['opt_caption'];?>" <?php if ($default == 1) {;?> checked="checked" <?php } ?> /><?=$optionrs['opt_caption'];?>

Here I tried to set the $opt by increment of 1 to send it as opt_1, opt_2, opt_3...
But i'm not able to receive these values on next page. Moreover, after all which options have been selected I want to separate them from blank values, so that the chosen values should be inserted in a table.

Highly thanks in advance...

Before we get to your problem... may I first ask why you're trying to generate radio buttons with unique names? The point of using radio boxes is to give a group of them (e.g. 2 or more) the same name, and letting the user choose only one option from that group.

If you want to allow the user to select one or more of the options without restriction, then you should probably be using a checkbox instead.

EDIT: Also, forgot to mention...

[/noparse] bbcode tags (versus the generic CODE tags) as they make your code much easier to read and analyze.

It's because that I've used double loop, which I forgot to mention. However, the full form code is given below, which will create better understanding for you:
