Is there a better way to do this? $p = 3; $a = 3; $b = 3; $arr = [$p,$a,$b]; if (in_array(0, $arr)) { return 'Pending'; } if ((in_array(2, $arr)) && !in_array(0, $arr)) { return 'Incomplete'; } if ((in_array(1, $arr)) && !in_array(0, $arr) && !in_array(1, $arr)) { return 'Approved'; } if (in_array(3, $arr) && !in_array(0, $arr) && !in_array(1, $arr) && !in_array(2, $arr)) { return 'Declined'; }

I can't figure out what's wrong with this. The program works, but the deduplication doesn't work. The error I get is : Warning: in_array() [function.in-array]: Wrong datatype for second argument in line 67. I bolded line 67 below, which is an if (in_array ) statement. in_array wants an array for the second argument, which I have, so don't see the problem. Any suggestions?

Hi! I have the following code for quick verification of uploaded files: // Validating the Image (file_upload) if (in_array("", $_FILES['file_upload']['name'])) $errorArray['Image File'] = "Browse and select a GIF/JPEG Image File to upload!"; elseif (isset($_FILES['file_upload'])) { foreach ($_FILES['file_upload']['type'] as $key => $type) { if (!($_FILES['file_upload']['type'][$key] =="image/jpeg" OR $_FILES['file_upload']['type'][$key]=="image/gif")) $errorArray['Uploaded Image'] = "Your uploaded file must be either JPG or GIF only!"; elseif (!doesuserfile_nameEventBannerExist($_FILES['file_upload']['name'][$key])) $errorArray['Uploaded Image'] = "Filename already Exists, Rename and Upload again!"; } } I can upload 7 files at one time and there's no error. More than 7 files at one time, I get an error saying: Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/user/imageuploader.php Please help ! Thank you.

I'm new to the site here, so I hope this is the right place for this post. It's also from a Wordpress site, but since Wordpress isn't the issue (and my [lack of] programming knowledge is), I figured this wouldn't fit on the Wordpress forums very well. So here's my problem. I downloaded a plugin which I'm trying to modify, and it's breaking my site (internal server error), which always makes for a fun day. Here's the piece I'm inserting: // ---START--- Add Buddypress 'Friends' filter. $wpdb->show_errors(); $k_user_id = $current_user->ID; $k_friends1 = $wpdb->get_col( "SELECT initiator_user_id FROM $wpdb->prefix . 'bp_friends' WHERE friends_user_id = $k_user_id AND is_confirmed = 1" ); $k_friends2 = $wpdb->get_col( "SELECT friends_user_id FROM $wpdb->prefix . 'bp_friends' WHERE initiator_user_id = $k_user_id AND is_confirmed = 1" ); $k_friends = array($k_friends1, $k_friends2); foreach($workers as $x) { if(!in_array($x, $k_friends, TRUE) { unset($workers[$x]); } } $wpdb->hide_errors(); The plugin has already defined the $workers variable, but I'd like to modify that variable by removing any values not contained in either of the two SQL queries. To provide more context, this plugin is an appointments plugin that I'm trying to integrate with Buddypress so that users can schedule appointments with each other, but only if they're friends. I know just enough php to get myself in trouble, so I'm sure there's something that's very obvious to everyone else, but I'm not seeing it...and it's very likely to do with me not understanding exactly how the functions are actually working. Any help would be very much appreciated. Thanks!
