[Resolved] Detecting post data?

brooky

Hi,

Can php detect post data. I'm parsing some dynamic variable from a multitude of dynamic select dropdowns named;

opt1
opt2
opt3.....
opt56
opt57 etc...

Can php detect post variables like "opt"?

Then for each I will put them into one variable to be expoloded later.

for each $opt{

$prod_options .=",$opt34"; etc...}

Any help much apreciated. 🙂

well $POST is an array. You can run a foreach and use $POST as your array argument.

If this doesn't do what you wanted, just elaborate a little more and we'll get this figured out.

Great thank so much for you help 😃

This will be awsome when done. I will play with that and add like "opt".

get post like opt and then for each stick them in one variable seperated by commas to be exploded later. I'll post the solution/progress here.

Thank again 😉

Getting there:

// get posted options
	 foreach ($_POST as $add_opt){
		$product_options .= "$add_opt,"; 	 
	 }

 // remove last comma
 $options_length = strlen ($product_options);
 $new_len = $options_length - 1;
 $product_options =  substr($product_options, 0, $new_len);

 echo $product_options;

That works fine but for all variables. I now need to trim it so it only works with post data like "opt".

Have no idea how right now😉

I hope others find this useful...

// get posted options not other form data
	 foreach ($_POST as $varName => $value){
		$opt_short = substr($varName, 3);
		if($opt_short=="opt"){ 
		$product_options .= "$value,";}
		}// remove last comma
	 $options_length = strlen ($product_options);
	 $new_len = $options_length - 1;
	 $product_options =  substr($product_options, 0, $new_len);
