hook_block makes other blocks disapear

By hypeweb on 17 Feb 2009 at 14:15 UTC

I have no idea why all my blocks disapear as soon as i enable my custom module. (which i have used before)
Any help much appreciated.

function test_block($op = 'list', $delta = 0, $edit = array()) {

	if($op == 'list') {

		$block[0]["info"] = t('test Navigation');
		// BLOCK_CACHE_PER_ROLE will be assumed for block 0.
	
		return $block;
		
	} else if ($op == 'view') {
		
		$block = array('subject' => t('testNavigation'), 'content' => test_display_block());
		
		return $block;
	}
}

List op returns $blocks

First,
The 'list' op should return array called $blocks not $block (hook_block()) ex:

....
if($op == 'list') {

$blocks[0]["info"] = t('test Navigation');

return $blocks;

} else if ....

Two, I think you should check the return of test_display_block() function. For testing you could just replace it with a string like:

.... 'content' => '<p>Hello World!</p>'

If the above snippet works, then you know it is that return of test_display_block() function is the culprit.

Is the function

Is the function test_display_block() defined somewhere?

Problem still persists

Ok sorry about the block -> blocks thing, should of known.
However my problem still persists. I have taken code from drupal api as is, and pasted it into the module and deleted
my functions. The problem still persists, after re saving modules, and clearing cache.

/**
 * Implementation of hook_block().
*/
function fruitrun_block($op = 'list', $delta = 0, $edit = array()) {

	switch($op){
		case 'list':
		$blocks[0]['info'] = t('pending comments');
		$blocks[0]['cache'] = BLOCK_NO_CACHE;
		return $blocks;
	}
}

So it appears just having the actual hook_block, makes all other blocks disapear.

Problem solved, by changing

Problem solved, by changing the module name. This is not realy a solution as I would of liked to know what caused this.
I even tried clearing any refernces to the module and block in the database, but that dident work. Good for now.
