delete spesific variable in array

[oaskedal]

Hi!

Ok, here's my problem:

The variable $delete returns a spesific value (e.g. 'someTablename') for the index ['Tablename'] out of the array.

I want the code under to delete the index ['Tablename'] with that spesific value, but this doesn't do it... What am I doing wrong?

$productTable = $_SESSION['aTable']; 

if($_GET['remove']) {  //fetched from the URL 

$delete =  $_GET['remove'];

	foreach($productTable as $key) {
	 foreach($key as $key2 => $value) {

	  if($key2=='Tablename') {

	    if($value==$delete) {

		   unset($key2 ->$value);

		   }

		}





	 }

	}
}

Close!

unset($key[$key2]);

hmmm... I tried that, but nothing happened. The output doesn't change when I output the array on the bottom of the page... Have I forgotten something?

The $key value is 'Array'. Is that right?

unset($productTable[$key][$key2]);

Ok, now it throws me :

Warning: Illegal offset type in..

Here is how the registration of the session array is done (the $name is a single variable, the $fieldname and $fieldvalue are arrays):

$_SESSION['productTable'][] = array("Tablename"=>$name, "Subject"=>$fieldname,"Value"=>$fieldvalue;

Does it have something to do with the values attached to it?
Here is an example of a print_r() output:

Array
(
    [0] => Array
        (
            [Tablename] => Test
            [Subject] => Array
                (
                    [0] => someValue
                )

        [Value] => Array
            (
                [0] => someOtherValue
            )

    )

[1] => Array
    (
        [Tablename] => Test 2
        [Subject] => Array
            (
                [0] => some value 
                [1] => some value
            )

        [Value] => Array
            (
                [0] => some value
                [1] => some value
            )

    )

strange..

Referencing that print_r() output, what exactly would you want to delete: the entire sub-array for the top [0] => array (...) sub-array? If so, you could do (untested):

$callback = create_function(
   '$var',
   'return($var["Tablename"] != "'.$delete.'");'
);
$productTable = array_filter($productTable, $callback);

Hi!

It should delete all :

[1] => Array  //this
        (
            [Tablename] => Test 2  //this
            [Subject] => Array  //this
                (
                    [0] => some value  //this
                    [1] => some value  //this
                )

        [Value] => Array  //this
            (
                [0] => some value  //this
                [1] => some value //this
            ) 

if 'Tablename' = Test 2
Does it reorder the index automatically, or how does it work when the whole index

[1] => Array

is gone?

[dougal85]

$productTable = $_SESSION['aTable']; 

if($_GET['remove']) {  //fetched from the URL 

$delete =  $_GET['remove'];

foreach($productTable as $key => $value) {

foreach($value as $key2 => $value2) {

	if($key2=='Tablename') {

		if($value==$delete) {

			unset($productTable[$key][$key2]);

		}

	}

}

}

}

If you want it renumbered, maybe the simplest thing to do would be:

$productTable = array();
foreach($_SESSION['aTable'] as $arr)
{
   if($arr['Tablename'] != $delete)
   {
      $productTabe[] = $arr;
   }
}
