Working with an array and $_POST values

[samoht]

hello all,

 

I want to have a few simple arrays to group certain products

 

so let say I have these arrays:

$materials = array('product1','product2','product3');
$glass = array('product4','product5','product6');

 

And I wanted to check my $_POST values to see if there is any products relating to this grouping and if so, Print something like:

Materials: 'proudct2'.

glass: 'product5', 'product6'.

 

 

how do I set this up??

You can use an in array function to check if the what your looking for is in the array.

Or use a database.

thanks EchoFool

 

I'm not exactly sure what to do with the $_POST array??

 

foreach ($materials as $material) {
if (is_array($_POST) && in_array($material,$_POST))

Ken,

 

I cant use the database because the form is not actually submitted yet but is just in confirmation stage.

 

Can any one help me with the in_array function because the above does not work.

 

Thanks,

if ( in_array($_POST['abc'] ,$glass) )
{
// Something
}

 

you even dont have to use a loop...

Thanks aviavi,

 

but that is checking for just one value 'abc'

what I need to do is loop through the post array to see if there are any of the values in the $glass array.

 

so if my post array looked like:

 

Array ( product2=>1, product5=>1, product6=>1)

 

then my ckeck for the products within the $glass array would trip because the $glass array has product5 and product6 in it.

 

If it helps these post values are coming from checkboxes and there is a list of over 30 of those. So my post array could have a lot of these product values in it and the client wants to group the output

 

Hope that helps,

correct me if i mistaken....

$_POST get some array...

and you want to check if some values of this array are exist in $glass array?

[samoht]

well $_POST is an array, but the checkboxes are separate inputs not an array of checkboxes - this has to do with database the client is working with.

 

So the main form has these...

<input  id="product1" name="product1" type="checkbox" value="1" /><label>Asphalt Paving:</label>
		<br />
		<input  id="product2" name="product2" type="checkbox" value="1" /><label>Aggregate/Fill:</label>
		<br />
...

OK I am off to a better start, the arrays need to match so since $_POST array looks like:

 

[product1]=>1

[product2]=>1

[product3]=>1

[product4]=>1

...

 

my $materials and $glass array needed to include the =>1

 

so now my problem is that I am trying to print the group name - but I only want to do that once if a value shows up??

 

Here is what I have:

$materials = array('product1'=>1,'product2'=>1,'product3'=>1);
	  foreach ($materials as $material) {
		if (in_array($material,$_POST))
			echo '<div class="product_divisions">Oldcastle Materials:</div>';
	  }

[samoht]

OK,

 

I created a function:

$Materials = array('product1'=>1,'product2'=>1,'product3'=>1);

ocMat($Materials, $_POST);
function ocMat($Materials, $_POST){
$found = false;
foreach ($Materials as $material) {
	if (in_array($material,$_POST)){
		$found = true;
	}
}
  return $found;
}

if(ocMat($Materials, $_POST)){
	echo '<div class="product_divisions">Oldcastle Material:</div>';
}
?>

 

which would work ok except it looks for any value in $Materials array as similar to the value in $_POST array. This is a problem because the value =>1  so of course it is going to be triggered if any checkboxes are checked.

 

Is there a way to check for the "name" in the array instead of the value??
