Exclude non-matches comparing multiple variables
I’ve managed to store some article IDs that I need in variables.
<txp:variable name="subject" />
<txp:variable name="type" />
<txp:variable name="creator" />
Those might output:
subject: 108, 192, 193, 194, 197, 1712, 1730, 1828, 1831, 1829, 1833, 1832, 1834, 1835, 1842, 1850, 1853, 1852, 1854, 1855, 1856, 1857, 1859, 1858, 1863, 1864, 1865, 1866, 1867, 1870, 1871, 1872, 1873, 1874, 1875
type: 147, 1874, 2115, 2216, 2249, 2251, 2327, 2347, 2356, 2358, 2361, 2369, 2367, 2366, 2476, 2485, 2570,
creator: 1874, 1892,
A comparison:
1874 is the only ID present in each list.
What might be a good way to put any matches in to a new variable?
<txp:variable name="matched_ids" />
matched_ids: 1874
I’m looking at implode…

Re: Exclude non-matches comparing multiple variables
Though ugly, something like this should work:
<txp:php>
variable(
array('name' => 'matched_ids'),
implode(',', array_intersect(do_list(variable(array('name' => 'subject')), do_list(variable(array('name' => 'type')), do_list(variable(array('name' => 'creator')))
);
</txp:php>Offline
Re: Exclude non-matches comparing multiple variables
I’ll admit this is new too me so instead of interpreting / modyfying what you wrote I just copied and pasted it in. Trying your suggestion as is resulted in:
Parse error: syntax error, unexpected ‘;’ in /Users/joshuavaage/Dropbox/httpdocs/freeathena.com/textpattern/publish/taghandlers.php(3836) : eval()’d code on line 5
I have had no luck yet with what I’ve come up with so far:
<txp:php>
$subject_id_array = '<txp:variable name="subject" />';
$type_id_array = '<txp:variable name="type" />';
$creator_id_array = '<txp:variable name="creator" />';
$a1=explode(",", $subject_id_array);
$a2=explode(",", $type_id_array);
$a3=explode(",", $creator_id_array);
$result=array_intersect($a1,$a2,$a3);
$matched_ids = implode(",", $result);
echo $matched_ids;
</txp:php>This is new territory for me so I’m a little confused.

Re: Exclude non-matches comparing multiple variables
Sorry, I have lost few )s:
<txp:php>
variable(
array('name' => 'matched_ids'),
implode(',', array_intersect(do_list(variable(array('name' => 'subject'))), do_list(variable(array('name' => 'type'))), do_list(variable(array('name' => 'creator')))))
);
</txp:php>Your solution is roughly the same, but <txp:variable name="subject" /> will not be parsed inside <txp:php>, you should replace it with variable(array('name' => 'subject'))

Re: Exclude non-matches comparing multiple variables
I went with your solution. It works great. Mine, I was unable to get working and had run out of patience with it. Thanks for taking the time to look at this with me.

That’s strange, it should be fine once txp tags are replaced with functions (or global $variables). I’d also use Textpattern do_list function instead of explode, just in case your variables contain spaces between ids:
<txp:php>
$subject_id_array = variable(array('name' => 'subject'));
$type_id_array = variable(array('name' => 'type'));
$creator_id_array = variable(array('name' => 'creator'));
$a1=do_list($subject_id_array);
$a2=do_list($type_id_array);
$a3=do_list($creator_id_array);
$result=array_intersect($a1,$a2,$a3);
$matched_ids = implode(",", $result);
echo $matched_ids;
