Multiple POST variables into an Array

[14pulsars]

Hi Guys, php noobie here:

 

I have a bit of a problem: I need to receive an indeterminate amount of similar POST variables (they are SKU's from a shopping cart). I want to place them in an array for later use and comparison with another array used to print item details based on the SKU.

 

I tried this to place the SKU's in an array, but I get an error on the 'if' line. (unexpected T_VARIABLE, expecting ']')

Obviously, there is a syntax error, but how is the following code invalid? Any suggestions?

 

$sku = array($_POST['sku1']);
for ($i = 2; $i<19; $i++) {
if (isset($_POST[sku$i])) {
	$sku[$i-1] = $_POST[sku$i];
}else{ break; }
}

Try this:

 

<?php
$sku = array();
for ($i = 1; $i<18; $i++) {
if (isset($_POST['sku'.$i])) {
	$sku[$i] = $_POST['sku'.$i];
}else{ break; }
}
?>

And to make things simpler, you could consider naming the input fields with the SKU data "sku[]". Then $_POST['sku'] contains an array of values from the SKU input fields (= what you're looking for).

Hey, that worked! Thanks.

 

I didn't think about bringing in the first array addition into the loop.

I also did not know you could concatenate inside variables like that. THANKS!

 

I'm going to remember this!

 

Try this:

 

<?php
$sku = array();
for ($i = 1; $i<18; $i++) {
if (isset($_POST['sku'.$i])) {
	$sku[$i] = $_POST['sku'.$i];
}else{ break; }
}
?>

The problem is that I don't have access to those fields, the data comes from the POST from a third party CC processor. Absolutely no control over field names or anything.

 

Though your suggestion would have been ideal.
