Hello, How do I remove an element from an array? Here is my current code $sql = mysql_query("SELECT suitenos FROM gssettings WHERE id=1"); $row = mysql_fetch_assoc($sql); $suites = split(",",$row['suitenos']); $number_of_suites = count($suites); for($i=0;$i<$number_of_suites;$i++) { if($suiteno == $suites[$i]) { $selected = "SELECTED"; } else { $selected = ""; } echo<<<endhtml <option value="$suites[$i]" $selected>$suites[$i]</option> endhtml; } Now I have another table in my database called "gsdays" that holds values of suite numbers that are already booked. What I want to do is remove any suite numbers that are already booked from my $suites array. To get the booked suites, I would do the following query. $query = mysql_query("SELECT suite FROM gsdays WHERE date='2007-03-24'"); $row = mysql_fetch_assoc($query); $booked_suites = $row['suite']; so basically what I want to do is remove $booked_suites from $suites. I tried using array_splice but I don't know what I'm doing

Well since nobody helped me I managed to research it and find it myself... here are the answers.. no cache: Header('Cache-Control: no-cache'); Header('Pragma: no-cache'); then to get all the checkboxes to another page, name them as follows <input type=checkbox name=checkbox[$id]> then in the php page, treat $_POST['checkbox'] as an array. Hope this helps someone in the future.

Two part question: #1. I've built a little AJAX app, but the problem is anytime I do an update, I have to delete my temp files before I can see the update. Is there anyway around this? #2. Is there a way to know all the variables submitted to a form without knowing what the variables are before hand? For example, I have a form, where there are checkboxes. Each checkbox's name is an ID value from the database. When I submit the form, I need to know all the rows that were checked...

I highly recommend you read PHPFreaks' tutorial on file uploading. I have been using this class for years now and it works perfectly... and has a function to specify the file formats you want to allow. http://www.phpfreaks.com/tutorials/85/0.php Hope that helps!

yeah I can't use move_uploaded_files() because the perl script has already uploaded it and moved it. I'm aware of the open, read, copy, save and delete method but some of these files are 25MB+... don't wanna break my server :(

[code]$textarea = "this is some text with 15 words in it"; $words = split(" ",$textarea); for($i=0; $i<15; $i++) { echo $words[$i]; }[/code]

what does your form look like? Are you sure you have the correct enctype?

what does your 'stripurl' function look like?

[code] $total = $amount1 + $amount2 + $amount3; $totalamount = number_format($total); mysql_query("INSERT INTO table (amount1,amount2,amount3,totalamount) VALUES ('$amount1','$amount2','$amount3','$totalamount')"); [/code]

Hello, I'm currently using a perl script to upload files (i'm using perl so I can use an AJAX progress bar) however since I don't know perl at all and have no desire to, I would like to use a PHP script to do what I want to do. Right now, the perl script uploads the files to /uploads/ then redirects to a page called finished.php. I need the files to go to different directories depending on who is logged into the system. I need to know how to move a file to a different directory in PHP. Is there a function to do this? Thanks, Barry

omg that saddens me to know that perl > php in this department :(

Hello, I've searched all over the internet for an upload progress meter bar, and I found a few... but unfortunatley I can't get any of them to work because they all need different extensions and libraries that my server won't allow... so I need to write my own. I know how to do everything except, get the progress/status of an upload. Is there a function in PHP that lets you know how many bytes have been uploaded... or a way to constantly check the filesize of a file while it's being uploaded?

well noone replied and i figured it out... if anyone was curious here was my solution: [code] if ($handle = opendir('/home/dtech/public_html/whereisit/maps/')) { while (false !== ($file = readdir($handle))) { if ($file != "." && $file != "..") { //echo $file; $image = exif_read_data("maps/$file",0,true); $images = array(); $images[$file]["lat"][0] = str_replace("/1","",$image['GPS']['GPSLatitude'][0]); $images[$file]["lat"][1] = str_replace("/1","",$image['GPS']['GPSLatitude'][1]); $images[$file]["lat"][2] = str_replace("/1","",$image['GPS']['GPSLatitude'][2]); $images[$file]["log"][0] = str_replace("/1","",$image['GPS']['GPSLongitude'][0]); $images[$file]["log"][1] = str_replace("/1","",$image['GPS']['GPSLongitude'][1]); $images[$file]["log"][2] = str_replace("/1","",$image['GPS']['GPSLongitude'][2]); print_r($images); } } } [/code]
