Ordering an array by another array?

[RJP1]

Hi guys,

 

I'm trying to modify a Joomla listings directory component to have a sorting capability on category pages that list listings. A bit like eBay, price high to low etc.

 

The basic code that outputs each listing is as follows...

 

foreach ($this->links AS $link) {
	$fields = $this->fields[$link->link_id];
	include $this->loadTemplate('sub_listingSummary.tpl.php');
}

 

I have so far been able to get the contents of an extra field into an array within this foreach loop like this:

 

$sleeps_array = array();
foreach ($this->links AS $link) {
	$fields = $this->fields[$link->link_id];

	$sleeps = $fields->getFieldById(51);
	if(!is_null($sleeps) && $sleeps->hasValue()){
	$sleeps = $sleeps->getOutput(1);
	$sleeps_array[] = $sleeps;
	}
	include $this->loadTemplate('sub_listingSummary.tpl.php');
  	}
sort($sleeps_array);
foreach ($sleeps_array as $key => $val) {
    echo "sleeps_array[" . $key . "] = " . $val . "\n";
}

 

I've got this far but simply adding the include file to the new loop for "sleeps" does not work. I think I need to some how link the 2 arrays so that I can sort listings by the custom field... Can anyone point me in the correct direction?

 

Thanks! RJP1

Show a var_export() of your arrays and explain which one you want sorted by what element etc...

I did this:

var_export($sleeps_array);

var_export($this->links);

 

For the first $sleeps_array I got:

array ( 0 => '6', 1 => '4', 2 => '2', )

 

For the second array (the one which looks like has all the listing data - and also looks "cut off"):

array ( 0 => stdClass::__set_state(array( 'link_id' => '6',

 

Thanks for the help! RJP1

Ah, it wasn't cut off, just below the listings... but it doesn't show the data for this custom field (well, not obviously anyway...).

[RJP1]

This data is actually held in var_export($fields). E.g.

 

'Sleeps', 'value' => '2',

I'm going to be looking at this again today, I had a brief break from it. Anyone have any ideas of how I should go about this?
