Retrieving Values from an Out of Order Array

[KariAnn0]

Ok, this is my array.

Array ( [12] => 4 [24] => 1 )

When I do a count( $myarray ); it returns 2.

But when I step through to retrieve the values:

for( $i=0; $i< count( $imyarray ); $i++ ){

$val = $mayarray[$i];

}

It doesn't return the right values, obviously because it is looking for $mayarray[0], $myarray[1] which has nothing.

So how can I loop through and retrieve the values, the length of the array is always changing. Also, I the keys are always changing, it is from a multiple select in a form which is populated by a table, so the keys are the primary key from the table, so they are never in order. Any ideas would be appericated. It's Friday and I can't think.

foreach($array as $key => $value)
{
//do shit with each value and key
}

were key would be 12 and value 4

I did try that, the only thing is $myarray is being passed to a function where i would need to retrieve the values, here it is:

function InsertNewAcc( $idvalue, $insert_flag ) {

$manid 		= 0;
$famid 		= 0;
$modelid 	                = 0;

$count = count( $idvalue );


for( $i=0; $i< count( $idvalue ); $i++ ){

if( $insert_flag == 'M' ) $manid = $idvalue[$i]; 
if( $insert_flag == 'F' ) $famid = $idvalue[$i];
if( $insert_flag == 'D' ) $modid = $idvalue[$i];

           //Doing more processing here

           }

}

when I use the foreach, it gives me an error on the $idvalue array.

 <?php
function InsertNewAcc( $idvalue, $insert_flag ) { 

$manid = 0; 
$famid = 0; 
$modelid = 0; 

$count = count( $idvalue ); 


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

if( $insert_flag == 'M' ) $manid = $idvalue[$key]; // or just $manid= $value
if( $insert_flag == 'F' ) $famid = $idvalue[$key]; 
if( $insert_flag == 'D' ) $modid = $idvalue[$key]; 

//Doing more processing here 

} 
} 
?>

Well I tried that, but now I am getting:

Warning: Invalid argument supplied for foreach() in D:\Www\Kari\USAnotebook\admin\inc\accessory_func.php on line 195

I am calling it like this:

InsertNewAcc( $manufact, "M" );

where $manufact is the database populated select.

Any Ideas now? Thanks Again.

then $idvalue is not an array

can they pick multiple items from the select box

[KariAnn0]

Yes they can pick multiple values form the select and they are put into the $manufact[] array. Then I am passing the $manufact array, or atleast that is what I am trying to do. Shouldn't the function treat $idvalue as the array that is being passed?

[sidney]

can you post the section with foreach loop in and section that calls it

[KariAnn0]

Hope this helps. There the selects, then calling the function and then the function itself.

<?php
echo<<<EOD
<td rowspan=2>".input_select("manufact[]", $man_arr, $man, "", "", "multiple=yes")."</tD>
<td rowspan=2>".input_select("family[]", $fam_arr, $fam, "", "", "multiple=yes")."</tD>
<td rowspan=2>".input_select("model[]", $mod_arr, $mod, "", "", "multiple=yes")."</tD>
EOD;

                            InsertNewAcc( $manufact, "M" );
	InsertNewAcc( $family, "F" );		
	InsertNewAcc( $moddel, "D" );

function InsertNewAcc( $idvalue, $insert_flag ) {

global  $id;

$manid 		= 0;
$famid 		= 0;
$modelid 	= 0;

$count = count( $idvalue );


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

	if( $insert_flag == 'M' ) $manid = $idvalue[$key]; 
	if( $insert_flag == 'F' ) $famid = $idvalue[$key];  
	if( $insert_flag == 'D' ) $modid = $idvalue[$key];  


if ( ( $manid > "" ) Or ( $famid > "" ) OR ( $modid > "" ) ) {

	$qry = "SELECT modelid, famid, manid, ntbid FROM accessory_model 
		Where modelid = $modelid and famid = $famid and manid = $manid and ntbid = $id";

	$res = mysql_query($qry);

	$count = mysql_num_rows( $res );


	if ( $count == 0 ) {

		$sqlqry = "INSERT INTO accessory_model ( modelid, famid, manid, ntbid ) 
			VALUES ( '$modelid', '$famid', '$manid', '$id' )";

		mysql_query($sqlqry);



	}

}

}

?>
