[RESOLVED] Using a multidimensional array

[_NL_Ren__]

Hi,

For some reason php doesn't like it anymore, yes it did work, if i do something like this:

$iCD = $PHP['oClasses']['oTemplate']->addBlock( array(
	'TPL_CD' => array(
		'TPL_BAND'	=>	$sBand
	)
), $iBand );

While it works without the $iBand argument. This number is the ID of a block added earlier so this one becomes a child of it.
The function addblock is defined this way:

function addBlock( $oBlock, $iID='') {
	......

return $this->iTPLBlock++;
}

Does anyone has an idea what i am doing wrong?
It also might be a setting which is wrong, had a new install lately but restored the settings.

Well, are you getting an error? What exactly do you mean "php doesn't like it anymore"?

I know it's silly but try changing this:

)
), $iBand );

To this:

)), $iBand );

hth.

thanks for the reply

ill explain what i mean:
The function addBlock doesn't see $oBlock as the array i send but as NULL.
This only happens when I also give a second argument.

removing the newlines don't have any affect 🙁

It has to be your logic/code. Let's see the full exact code of the addBlock() function so people on this forum can help you better. Also, exact examples of values passed, like what does $sBand contain.

Ok ill post a bigger part of the code hope it make it more clear.

A while ago i wrote this code for a music database, it scans the ID3 tags from mp3's on a cd. This code is from a page were a list of all the albums from every band in the db are created.

while ( list( $sBand ) = each( $oList )) {
	$iBand = $PHP['oClasses']['oTemplate']->addBlock( array(
		'TPL_BAND'	=>	array(
			'TPL_BAND'	=>	$sBand
			)
	));


if ( isset( $oList[ $sBand ]['oCD'] )) {
	while ( list( $iID, $sCD ) = each( $oList[ $sBand ]['oCD'] )) {
		$iCD = $PHP['oClasses']['oTemplate']->addBlock( array(
			'TPL_CD' => array(
				'TPL_BAND'	=>	$sBand
			)
		), $iBand );

		unset( $iID );
		unset( $sCD );
	}
}

unset( $sBand );
}

$oList is an array which looks like this:

$oList[ bandname ] = array(
	[ cd-id ] => cd-name
)

And now the troublemaker, addBlock is part of large template class. These are the first lines which generate errors:

function addBlock( $oBlock, $iID='') {
	if ( !is_array( $oBlock )) {
		trigger_error("Template->addBlock : The argument given must be an array not a(n) " . gettype( $oBlock ), E_USER_WARNING );
	}

list( $sBlockName ) = each( $oBlock );

And this is the error generated by the code above:
Warning: Template->addBlock : The argument given must be an array not a(n) NULL in D:\Web\Online\music_module\template.php on line 75

Warning: Variable passed to each() is not an array or object in D:\Web\Online\music_module\template.php on line 78

I don't know what to tell ya. Maybe you don't really have '!' or you have a ';' on the 'if' statement line. Maybe the array is not setup the way you think it is. Do a print_r() on the $oList array variable.

What version of PHP are you running? I ran the following code in PHP version 4.3.11 and 5.0.4 without the error being triggered. Try running the same code below and see what happens.

$oList['band1'] = array('cd-id1' => 'cd-name1');
$oList['band2'] = array('cd-id2' => 'cd-name2');

function addBlock( $oBlock, $iID='') {
    if ( !is_array( $oBlock )) {
        trigger_error("Template->addBlock : The argument given must be an array not a(n) " . gettype( $oBlock ), E_USER_WARNING );    }

echo 'in addblock<br>';
list( $sBlockName ) = each( $oBlock );
}

while ( list( $sBand ) = each( $oList )) {
	$iBand = addBlock( array( 'TPL_BAND' => array( 'TPL_BAND' => $sBand ) ));
	if ( isset( $oList[ $sBand ]['oCD'] )) {
		while ( list( $iID, $sCD ) = each( $oList[ $sBand ]['oCD'] )) {
			$iCD = addBlock( array( 'TPL_CD' => array( 'TPL_BAND' => $sBand ) ), $iBand );
			unset( $iID );
			unset( $sCD );
		}
	}
	unset( $sBand );
}

Thanks for the help, but i allready sorted it out. Though the solution raises a litle question itself 😛

In the template class there was a function wich uses references like this

function &getBlockById( $iID, &$oBlock ) {
	reset( $oBlock );

while ( list( $sKey ) = each( $oBlock )) {
	for ( $i = 0; $i < count( $oBlock[ $sKey ] ); $i++ ) {
		if ( $oBlock[ $sKey ][ $i ]['ID'] == $iID ) {
			return $oBlock[ $sKey ][ $i ];
		}

		if ( isset( $oBlock[ $sKey ][ $i ]['BLOCK'] )) {
			$oNested =& $this->getBlockById( $iID, $oBlock[ $sKey ][ $i ]['BLOCK'] );

			if ( !is_bool( $oNested ) && is_array( $oNested )) {
				return $oNested;
			}
		}
	}
}

return false;
}

And changed return false into :
$bReturn = false;
return $bReturn;

it got rid of all the errors and the script work properly now, but whats so special about this 'fix'?
