[PHP] unable to use vars in foreach
I'm using PHP 5.0.2
Here is a snippet of my code
$post=$_POST;//this is actually happening in an include somewhere else and
autoprepended. Works just fine.
$modules = simplexml_load_file(MODULES);
foreach ($modules-module as $mod) {
echo $mod-postName.'br';
if (isset($post[$mod-postName])) {
die('in post');
.
echo-ing the postName works just fine, but when I get to the checking
whether or not the val is set, I get the error:
Warning: Illegal offset type in unset in /var/www/.
If I replace $post[$mod-postName] with a hardcoded val, it works
$post['news']
The values of $mod-postName are names of checkboxes.

Re: [PHP] unable to use vars in foreach [updated question]
So, searching php.net (I swear I did before...) I found this at http://us2.php.net/language.types.array You cannot use arrays or objects as keys. Doing so will result in a warning: Illegal offset type. Neverthought that my var was an object, just thought maybe a string. My new question is, how can I convert this object to a string? Or get the val of it Here is my XML module name=News postNamenews/postName pageLevelPermissionsNews : Add authenticatedPagenews.add.php/authenticatedPage navDisplay page=/news/news.add.phpAdd/navDisplay /pageLevelPermissions pageLevelPermissionsNews : Current authenticatedPagenews.current.php/authenticatedPage navDisplay page=/news/news.current.phpCurrent/navDisplay /pageLevelPermissions pageLevelPermissionsNews : Archived authenticatedPagenews.archived.php/authenticatedPage navDisplay page=/news/news.archived.phpArchived/navDisplay /pageLevelPermissions /module -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

My issue is in the conditional. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

My issue is in the conditional. AHA! Here's what I think's going on (sorry I don't have time to investigate it myself) $mod-postName is a simplexml object. Due to some php5 magic, when used it a situation that calls for a string (like echo $xmlobj), it echos the proper value. However, when using it as an array subscript does not appear to qualify as this situation. To solve this try either: $post[(string)$xmlobj] OR $post[strval($xmlobj)] I hope this is clear and helpful. -ryan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] unable to use vars in foreach
ah yes thanks both worked... I had written a function to this... I knew there had to be a much easier way!!!
