  1. Say I have a table called artists with these fields (artistid, rank). Then say I have an array called $rankadjustments with a value for each artist (like 1, 7, 3,-3, 5, 9, etc). I am doing a MYSQL query that gets the info from artists table and sorts according to the rank field like this... $sql = "SELECT * FROM artists ORDER BY rank"; Easy enough. But what if I would like to bring that data back sorted by (rank + rankadjustment). For example, if the artist ranked 1st had a rank of "1" from mysql, but had a rankadjustment of "5" from the rankadjustment array, his "true" rank would be "6". Again, rankadjustment is NOT a field in my table, otherwise it would obviously be simple. It's calculated on the fly and stored in an array. FYI, the array has an index with their "artistid". For example, $rankadjustment[341][8] would be the artist with an artistid of "341" has a rank adjustment of 8. Is there a way to do this IN the query itself? It doesn't seem possible but wanted to find out for sure. If not, what is best way to do? I assume... Get the data sorted JUST by rank and put it all into an array, then create a new array that adds rank to rankadjustment and reorder by the "new" rank amount? I guess that wouldn't be too bad but again, wanted to make sure I'm not missing something that would allow me to do it all in the query (or just more efficiently). Thanks!
  2. Hi Im new here.. Im a PHP noo-b i have this simple code with sorting and pagination with dummy data (firstname,lastname,age) I would like to add some simple search to it..im not sure if im doing this right currentlty the search is not working properly for testing purpose, right now i limit 3 records per page a. when i search record and search result is display..Pagination link is still display even i have only 1record search result b. if i have 4 records found, when i click the 2nd page, the search result is gone and table is back to default view c. in table default view, clicking 2nd page and try to search record, records are not found because its looking under the 2nd page and not all of the table sorry for my English <!doctype html public "-//w3c//dtd html 3.2//en"> <html> <head> <title>Paging</title> </head> <body bgcolor="#ffffff" text="#000000" link="#0000ff" vlink="#800080" alink="#ff0000"> <form method="post" action="" > <br />Search <input type="text" name="search" /> <input type="submit" value="Search"/></form><br /> <?php require "connect.php"; // All database details will be included here // define values the rest of the code uses $table = 'person'; // database table name $sorts = array('firstname'=>'First Name','lastname'=>'Last Name','age'=>'Age'); // list of permissible sort choices $sort_bys = array('asc','desc'); // list of permissible order by choices $limit = 3; // No of records to be shown per page. // condition inputs/set default values $start = (isset($_GET['start'])) ?

  3. Hey guys: I have a database that is full of items. Each item lives in a box, with various accessories. I'm trying to loop through this DB to print out a label for each case that shows the amount of items that are in the case, along with the accessories that belong to it. I currently have a rather convoluted bit of code, that kind of works, but doesn't have the order that I want. My result is currently this: 4 X Generic lighting hanging clamp 4 X Generic lighting hanging clamp 4 X Generic lighting hanging clamp 4 X Generic lighting hanging clamp 4 X Generic lighting hanging clamp 2 X 25kg Safety Bond 2 X 25kg Safety Bond 2 X 25kg Safety Bond 2 X 25kg Safety Bond 2 X 25kg Safety Bond 2 X 16a to Powercon 2 X 16a to Powercon 2 X 16a to Powercon 2 X 16a to Powercon 2 X 16a to Powercon ********** 12 X Generic lighting hanging clamp 6 X 25kg Safety Bond ********** All the information is there, but due to the way that it loops through it's in the wrong order. I'd like it to be grouped so it looks like this so that it is grouped by box: 4 X Generic lighting hanging clamp 2 X 25kg Safety Bond 2 X 16a to Powercon 4 X Generic lighting hanging clamp 2 X 25kg Safety Bond 4 X Generic lighting hanging clamp 2 X 16a to Powercon 4 X Generic lighting hanging clamp 2 X 25kg Safety Bond 2 X 16a to Powercon 4 X Generic lighting hanging clamp 2 X 25kg Safety Bond 2 X 16a to Powercon ********** 12 X Generic lighting hanging clamp 6 X 25kg Safety Bond ********** Here is the code that I'm using. At the moment I'm just concentrating on the if ($item_type == '2') part, but have shown the whole lot so you can see what I'm doing. foreach ($distinct_path as $path) { $sql = "SELECT * FROM current_items WHERE path = '$path'"; $result = $con->query($sql); if ($result->num_rows > 0) { // output data of each row while($row = $result->fetch_assoc()) { $item_name = $row['item_name']; $item_type = $row['item_type']; $item_qty = $row['qty']; $case_qty = $row['case_qty']; if ($item_type == '1') // THESE ARE MAIN ITEMS { $total_main_qty = $row['qty']; //main item QTY; $main_item_name = $item_name; } // This code will tell us number of full boxes, and number of extra lights left over $amtoffull = $total_main_qty/$case_qty; $amtoffull = floor($amtoffull); // we round down to the nearest whole number $total_left = $total_main_qty - ($case_qty * $amtoffull); if ($item_type == '2') // THESE ARE ACCESSORIES { $asc_qty = $row['qty']; //main item QTY; $asc_qty = $asc_qty/$total_main_qty; // THIS GIVES US THE TOTAL OF ONE Item $asc_qty = $asc_qty * $case_qty; // This is a full case amount //echo $asc_qty ." x ". $item_name ."</p>"; while ($i < $amtoffull) { echo $asc_qty ." X ". $item_name ."</p>"; ++$i; } } $i = 0; } echo "**********"; echo "<p>"; } I think I need to either shift the loops around so they work in a different order, or store everything into an array and then loop through that. Can any one help?
  4. I have a script that retrieves the names of photos in a photo directory. I want to sort them by the names, but my sorting isn't working. Everything seems to work except the order is wrong. My code is below. Any help is appreciated. $path = "../arrangements"; if(isset($_POST['file']) && is_array($_POST['file'])) { foreach($_POST['file'] as $file) { unlink($path . "/" . $file) or die("Failed to <strong class='highlight'>delete</strong> file"); } } $path = "../arrangements"; $dir_handle = @opendir($path) or die("Unable to open folder"); while (false !== ($file = readdir($dir_handle))) { sort($file); if($file == ".") continue; if($file == "..") continue; echo "<img src='../arrangements/$file' alt='$file'><br />"; $filename = substr($file, 0, strrpos($file, ".")); echo $filename; }
