PHP - Logic To Remove Array Items As A Recommendation Engine To Show Best Solution
I have users in my database with many stored points ie age, gender, interests etc. about 20 points in all.
I have a table of products that I want to recommend only applicable products. They each have saved like minage, maxage, gender, interest etc for the ideal consumer. ie dress gender=f
This is the bare bones of what I have so far:
$result = mysql_query("SELECT * FROM user_table WHERE hash='$session_id'"); $rowuser = mysql_fetch_array($result); $result = mysql_query("SELECT * FROM products"); $rowproducts = mysql_fetch_array($result);So now I have $rowuser['gender'] = m , how do I remove all from $rowproducts where gender = f? Is there a best way to do this knowing I have about 20 points to go through before I am left with an array with just the best selection of products for this user in it? Similar TutorialsWhen I remove 1 session item using this it works fine when I select more than 1 item to be removed I get unexpected results, I have checked the outputted html to see what positions get echoed into the remove check box and they are correct, so I guess the problem lies in my remove code here is the part of the form that sends the remove check box <?php for ($basket_counter=0;$basket_counter<$_SESSION['ses_basket_items'];$basket_counter++) { $price=sprintf("%01.2f",$ses_basket_price[$basket_counter]); $quantity=$ses_basket_amount[$basket_counter]; $code=$ses_basket_stockcode[$basket_counter]; $itemID=$ses_basket_id[$basket_counter]; $name=$ses_basket_name[$basket_counter]; $image=$ses_basket_image[$basket_counter]; $size=$ses_basket_size[$basket_counter]; $sizechoice=$ses_basket_sizechoice[$basket_counter]; // create array from sizes and make the option box selections if ($sizechoice!="" && (!in_array($sizechoice, array('One Size', 'one size', 'free size', 'Free Size', 'Adjustable', 'adjustable')))) { // add size trigger $sizelist="add"; //create the array $sizepick=explode(",", $sizechoice); } else { $sizepick=$sizechoice; } // adjust gst for AU customers if ($country=='AU') { $price=sprintf("%01.2f",($price*1.1)); $unit=sprintf("%01.2f",($price/$quantity)); } else { $unit=sprintf("%01.2f",($price/$quantity)); } ?> <tr> <td align='center' class='rescon' style="border-bottom:solid #330000 1px;"><input type="checkbox" name="remove[<?php echo $basket_counter; ?>]" value="<?php echo $basket_counter; ?>" /></td> and here is the part of the code that processes the removal of the items $remove = $_POST['remove']; if (isset($remove) && ($remove!='')) { foreach($remove AS $key => $remove_position){ array_splice ($ses_basket_name, $remove_position, 1); array_splice ($ses_basket_amount, $remove_position, 1); array_splice ($ses_basket_price, $remove_position, 1); array_splice ($ses_basket_stockcode, $remove_position, 1); array_splice ($ses_basket_image, $remove_position, 1); array_splice ($ses_basket_size, $remove_position, 1); array_splice ($ses_basket_sizechoice, $remove_position, 1); array_splice ($ses_basket_id, $remove_position, 1); $_SESSION['ses_basket_items']--; } } I am using a form with checkboxes named remove[$remove_position] and the positions in the form are correct for each item in the array, but when I select more than 1 item to delete they are not always the correct items only the first 1 selected. What am I doing wrong here?? Hi guys! I'm trying to make a <select> button for car positions which displays a set of numbers like 1-5 or 1-10 so on.. I need to remove the numbers that is already been selected. Selected numbers are stored in the database and i fetch them in a simple query then compared it to the max number of cars. I have this code, it kinda works but it shows the number 1 which is already been selected. Selected numbers are 1 and 3, it successfully removes number 3 but not 1, The output is 1,2,4,5,6,7,8,9,10 I added some comments for clarity.. Code: [Select] function position_available($event_id, $number_of_cars) // receives id for ref. in the database { $selected_positions = check_selected_positions($event_id); // query to get selected positions while($positions = mysql_fetch_array($selected_positions)) { $position = array(); array_push($position, $positions['car_position']); // 'car position' is the name of the field } for($i = 1; $i <= $number_of_cars; $i++) // $number_of_cars is the total number of cars { if(! in_array($i, $position)) echo "<option value='{$i}'>" . $i . "</option>"; } } Did i miss something simple? thanks for the help in advance! I have say about 7 different interests and beside each interest I want a check box. How would I go about having multiple check boxes checked so I can remove however many interests at one time... For example: [Checked] Hockey Soccer Baseball [Checked] Basketball And the remove all selected button would remove the checked interests. Thanks, Sean For a long time, I think I have been using heading tags wrong on websites.
They always show like this on Google.

I'm trying to parse multiple rss feeds and only show and save items from the last month, but i can't get it to work. I've tried this: $pubdate = date("Y-m-d", strtotime($item->pubDate)); if (date($pubdate, strtotime(" -1 month")))
Hi all, I would like to ask you if somebody could have a better idea to build this function. The current one is working, but I feel this built a bit in an amateur manner. Feel free to add your ideas so we can learn more about PHP and how to deal with arrays.
I have an array: $arrayVideoSpecs = Array( Array( 'aspect' => '4:3', 'density' => '442368', 'resolution' => '768x576' ), Array( 'aspect' => '4:3', 'density' => '307200', 'resolution' => '640x480' ), Array( 'aspect' => '16:9', 'density' => '2073600', 'resolution' => '1920x1080' ), Array( 'aspect' => '16:9', 'density' => '121600', 'resolution' => '1280x720' ) );
and I want an array as output grouped by video aspect ratio where the key is the pixel density and the value is the video resolution, namely like that for aspect ratio 16:9 ... Array ( [2073600] => 1920x1080 [121600] => 1280x720 )
Then I coded this function which is working but seems amateur ... function groupAndExtractByAspect($array, $groupBy, $aspect, $density, $resolution) { $groupByAspect = Array(); foreach ($array as $value) { $groupByAspect[$value[$aspect]][] = Array($value[$density], $value[$resolution]); } $arrayClean = Array(); foreach ($groupByAspect as $key => $value) { if ($key == $groupBy) { $arrayClean[$key] = $value; } } foreach ($arrayClean as $aspectGroup) { $arrayOutput = Array(); for ($i = 0; $i <= count($aspectGroup); $i++) { $densityIsValid = false; $resolutionIsValid = false; if (!empty($arrayClean[$groupBy][$i][0])) { $density = $arrayClean[$groupBy][$i][0]; $densityIsValid = true; } if (!empty($arrayClean[$groupBy][$i][1])) { $resolution = $arrayClean[$groupBy][$i][1]; $resolutionIsValid = true; } if (($densityIsValid === true) && ($resolutionIsValid === true)) { $arrayOutput[$density] = $resolution; } } } return $arrayOutput; }
The usage is as follow ... $showArray = groupAndExtractByAspect($arrayVideoSpecs, '16:9', 'aspect', 'density', 'resolution'); echo '<pre>'; print_r($showArray); echo '</pre>';
Thank you very much for your ideas! Mapg Hi all. I am currently trying to build a site that will allow users to manage a self build house project. This is my first php MySQL project but I am getting to grips with it ok. I am currently building this for my own benefit at the moment as I am about to undertake a self build. I have a few questions to put to you guys. This is where I am at the moment I have a database table named materials which contains a list of materials , quantities, unit of measurement, id. My site has a user control panel that has separate forms for each stage of the build where the user enters the quantities of the materials, and the data is displayed as an array for each stage. So, heres question 1. I want to take the data and use it to generate a form which will be completed by several merchants.... so it will display similar to the array but will be a form with a text box for price where the merchant will insert a price. i.e <?php mysql_connect ("localhost", "test", "test") or die ('I cannot connect to the database becuase: ' . mysql_error()); mysql_select_db ("matquant"); // query $query = mysql_query("SELECT * FROM `quantites` ORDER BY `id` ASC"); // results while ($row = mysql_fetch_array($query)) { echo "<br />" .$row ['id']. " " .$row ['material']. " " .$row['quantity']. " " .$row['unit']. "<br />";} echo mysql_error(); ?> I want to add a text input box form which will allow the merchant to add a price to each item that is added to the array. so there the merchant will be able to give me a price for all the items in my list. Heres where I get stuck.... as I am constantly adding to the list I have no fixed amount of items so the form for the merchants needs to be built dynamically, ie each time I add a new material, I want the merchants form to get a new input. I am not very good at describing my problems but I am hoping that someone can help me out from the information given. Thats the first question. i like to get issues sorted in small bites. the second is the next big bite, I want to send the form above to several merchants, so I intend to have a user database with a user for each merchant, and link the tables so that each merchant can provide a price for each material, ideally the form would highlight the materials that have not had a price yet. I'm looking for advice on the best method of doing this basically but if I can get the first question sorted that would be great.. I have the test site local but can upload it it to the server if it will help you see what im trying to do. Any help that anyone can give will be greatly appreciated. Hi guys, I'm using the API for Remember the Milk through a PHP class that I found online called PHP-RTM. Anyway after so much headaches (the authentication for the Remember the Milk API is one of the hardest I've ever come across) I've finally connected everything and gotten to the stage that I have some raw data inside an array. The next step is to work with that data. Basically I want to access the names of the task in a complex multi demensional array and I have no idea how to do this. I have done a var_dump of the array I am working with to show you the complexity. Just remember that in the complex var_dump below there are only 4 tasks: array(2) { ["stat"]=> string(2) "ok" ["tasks"]=> array(2) { ["rev"]=> string(31) "nxeir6vy9pcgcggoss4wwwooc8cwo8w" ["list"]=> array(3) { [/tt][list][li][tt]=> array(2) { ["id"]=> string( 8) "13927305" ["taskseries"]=> array(2) { [/tt][/li][li][tt]=> array(11) { ["id"]=> string(9) "104056511" ["created"]=> string(20) "2011-02-02T12:48:48Z" ["modified"]=> string(20) "2011-02-02T12:48:48Z" ["name"]=> string(42) "Send confirmation email to luxury car hire" ["source"]=> string(13) "iphone-native" ["url"]=> string(0) "" ["location_id"]=> string(0) "" ["tags"]=> array(0) { } ["participants"]=> array(0) { } ["notes"]=> array(0) { } ["task"]=> array(9) { ["id"]=> string(9) "156815180" ["due"]=> string(20) "2011-02-02T13:00:00Z" ["has_due_time"]=> string(1) "0" ["added"]=> string(20) "2011-02-02T12:48:48Z" ["completed"]=> string(0) "" ["deleted"]=> string(0) "" ["priority"]=> string(1) "N" ["postponed"]=> string(1) "0" ["estimate"]=> string(0) "" } } [1]=> array(11) { ["id"]=> string(9) "104148150" ["created"]=> string(20) "2011-02-03T01:25:57Z" ["modified"]=> string(20) "2011-02-03T01:26:17Z" ["name"]=> string(40) "Confirm that post has been sent with DVD" ["source"]=> string(2) "js" ["url"]=> string(0) "" ["location_id"]=> string(0) "" ["tags"]=> array(0) { } ["participants"]=> array(0) { } ["notes"]=> array(0) { } ["task"]=> array(9) { ["id"]=> string(9) "156951316" ["due"]=> string(20) "2011-02-02T13:00:00Z" ["has_due_time"]=> string(1) "0" ["added"]=> string(20) "2011-02-03T01:25:57Z" ["completed"]=> string(0) "" ["deleted"]=> string(0) "" ["priority"]=> string(1) "N" ["postponed"]=> string(1) "0" ["estimate"]=> string(0) "" } } } } [1]=> array(2) { ["id"]=> string( 8) "13925842" ["taskseries"]=> array(12) { ["id"]=> string( 8) "98105089" ["created"]=> string(20) "2010-12-19T11:25:25Z" ["modified"]=> string(20) "2011-02-02T13:01:42Z" ["name"]=> string(25) "Read for one hour per day" ["source"]=> string(13) "iphone-native" ["url"]=> string(0) "" ["location_id"]=> string(0) "" ["rrule"]=> array(2) { ["every"]=> string(1) "1" ["$t"]=> string(21) "INTERVAL=1;FREQ=DAILY" } ["tags"]=> array(0) { } ["participants"]=> array(0) { } ["notes"]=> array(0) { } ["task"]=> array(9) { ["id"]=> string(9) "156576423" ["due"]=> string(20) "2011-02-02T13:00:00Z" ["has_due_time"]=> string(1) "0" ["added"]=> string(20) "2011-02-01T13:01:45Z" ["completed"]=> string(0) "" ["deleted"]=> string(0) "" ["priority"]=> string(1) "N" ["postponed"]=> string(1) "0" ["estimate"]=> string(0) "" } } } [2]=> array(2) { ["id"]=> string( 8) "17007566" ["taskseries"]=> array(11) { ["id"]=> string(9) "104017503" ["created"]=> string(20) "2011-02-02T05:45:04Z" ["modified"]=> string(20) "2011-02-03T02:29:55Z" ["name"]=> string(96) "Hook up watermark for both videos (check email) and send to Rachelle and Steve at compare quotes" ["source"]=> string(2) "js" ["url"]=> string(0) "" ["location_id"]=> string(0) "" ["tags"]=> array(0) { } ["participants"]=> array(1) { ["contact"]=> array(3) { ["id"]=> string(7) "2150286" ["fullname"]=> string(10) "Samuel Nam" ["username"]=> string(10) "samuel.nam" } } ["notes"]=> array(0) { } ["task"]=> array(9) { ["id"]=> string(9) "156754354" ["due"]=> string(20) "2011-02-02T13:00:00Z" ["has_due_time"]=> string(1) "0" ["added"]=> string(20) "2011-02-02T05:45:04Z" ["completed"]=> string(20) "2011-02-03T02:32:00Z" ["deleted"]=> string(0) "" ["priority"]=> string(1) "N" ["postponed"]=> string(1) "0" ["estimate"]=> string(0) "" } } } } } } Anyone know the code i can use to simply get the "name" keys from the complex array below.

[/list] okay I am using a jquery plugin to re-arrange images which are in mysql and they have their own "order_number" ... when i re-arrange stuff the new order is put into a hidden field in a form and i have it along with another hidden field with their current order... when submitted I combine these two fields in an array so the key is the original order and the value is the new order ....i have 12 images... Array ( [1] => 1 [2] => 2 [3] => 3 [4] => 4 [5] => 5 [6] => 6 [7] => 7 [8] => 8 [9] => 9 [10] => 10 [11] => 11 [12] => 12 ) this is what is what the array looks like... i have a foreach loop with a mysql query but things get kind of weird when you try to do it this way $num = $_POST['old_num']; $num = unserialize($num); $sort = $_POST['sortOrder']; $sort = explode(',', $sort); if ($_POST){ $combine = array_combine($num, $sort); foreach($combine as $key => $value){ mysql_query("UPDATE shirts SET order_number='$value' WHERE order_number='$key' ") or die(mysql_error()); } when you do this lets say for example we have the image with order number "1" get switched with the image order number "2"..... the database first updates with number 1 which becomes 2... then when it goes to number "2"... at this point... the first image gets switched back to number 1.... so 1 becomes 2 then the new 2 becomes 1 again and the other 2 becomes 1 also. I can not think of another way I could update mysql with the correct order numbers... If anyone has any ideas or other solutions I am open to all suggestions... thank you! Hi, I'm hoping someone can help me with a simply array problem. I have a table with two columns: "ID" and "Name" and 100 Names. I also have an array called $myIDList containing 10 IDs. I want to display 10 Names from the table that correspond with the IDs from my array. Originally, I tried to implode the array, adding commas and inserted into my MySQL query using: $myQuery = "SELECT ID, Name FROM namesTable WHERE ID IN ($myImplodedIDList)"; The problem was that duplicated names (i.e. the same Name, but assiged to different IDs) would only be displayed once. So now I'm trying to use the original array to loop through a second array and display Names where the ID matches an ID from my first array. I have succesffuly listed the table like this: $myQuery = "SELECT ID, Name FROM myTable ORDER BY ID"; $myResult = mysql_query($myQuery) or die(mysql_error()); while($row=mysql_fetch_array($myResult)) { echo $row['ID']; echo $row['Name']; } But I want to do something like: while($row=mysql_fetch_array($myResult)) { while $row['ID'] = $myIDList { echo $row['Name'] } } Can someone shed some light onto this for me please? Thank you! Bryan I have an array of products. The array has an ID and price. I'd like to know the most efficient way of adding up all the same ID fields in the array. Code: [Select] <?php $items[] = array( 'id' => 1, 'price' => 5.99, ); $items[] = array( 'id' => 2, 'price' => 1.99, ); $items[] = array( 'id' => 3, 'price' => 2.40, ); $items[] = array( 'id' => 2, 'price' => 6.99, ); $items[] = array( 'id' => 4, 'price' => 8, ); $items[] = array( 'id' => 2, 'price' => 3, ); $items[] = array( 'id' => 3, 'price' => 1, ); function add_like_items($items) { //manipulation return $sums; } //$sums would be an array like //$sum[1] = 5.99 //$sum[2] = 11.98 //$sum[3] = 3.40 //$sum[4] = 8 ?> Anybody have suggestions on the best way to go about doing this? How can I check if an array contains two items that are the same? For example ("apples", "bananas", "oranges") returns false But ("apples", "bananas", "bananas") returns true Hi guys, I'm just working on a script to get menu items from a database, sorted by a sort column. Each item needs to be checked to see if it has a parent, then paired with the parent. Would it be best to get all of the items at once and pair them with PHP, or get the children of each item when as a separate array? id label link parent sort 1 Home index.php 0 10 2 About about.php 0 20 3 Contact Us contact.php 2 10 Hi all, I have a table that shows data from an xml response that has been converted to an array. I have successfully managed to get that to work but it's showing more items than I want. I'm trying to isolate the items by state. There are 11 or so different states, of which I only want 7.

Hi, Im wondering if there is an easy way to get items out of an array returned by a function inside a class. A code example would be: Code: [Select] class modDB { public function getPwdSalt() { $arr = array("salt", "password"); return $arr; } } ?> And what i would like to be able to do is something like: Code: [Select] $modDB = new modDB; echo $modDB->getPwdSalt()->[1]; and just get returned 'password'. Is something like that possible? Many Thanks. Running a simple query: SELECT team, rank from table ORDER BY rank ASC returns 8 records in order from 1 to 8 I then want to a assign a new variable to each that I can use for later queries ie: team with rank 1 = $team1 team with rank 2 = $team2 team with rank 3 = $team3 etc....

I have now reached a point where I desperately need help from experts.
Quote from: Hollows on August 20, 2010, 11:29:25 AM I have an array that is pulling 10 results from a db like this - <?php $result = mysql_query("SELECT * FROM inbox ORDER BY id DESC LIMIT 0,10"); while ($row = mysql_fetch_array($result)) { <div class="<?php echo $row['class']; ?>"> <?php echo $row['name']; echo $row['message']; ?> </div> basically 'class' is defined in an earlyier part of the script and is used to tell the css what class to display - as I'm sure you can see. What I'd like todo then be able to update the class of a message once I have read it, so update the class table with something like 'read' so the css will then be based on .read not what ever was set by the form, either using a link or form button inside each of the 10 results from the array. I've managed to update one by using - Code: [Select] mysql_query("UPDATE shoutbox SET class = 'read' WHERE id = ''XX"); // XX should be row id But I had to set that myself and point the id to the row id I wanted to change - How can I have that already populated with the row for the id that triggered it? To be clear so it looks like - Name Message read button _____________ Name Message read button _____________ Name Message read button _____________ and so on... Would I be better going by check boxes and one submit button? If so how could I implement that? I can provide the full code I've written if it helps Thank you in advance -First I want to say that I love this site and always check google before I submit questions but im lost. I'm into security and trying to learn a little Apache, Mysql, and PHP to understand the development cycle better. As practice im creating a notecard test review site. Create notecard Decks, add/delete questions etc. shuffle, then test yourself. I though I was doing good until I got to the page that shows the questions (test.php). Right now I pass the "deck_id" field in a GET to a "test.php?id=" page that runs a script that pulls out all the questions for that deck from my "questions" table and loops to show each question for that "deck". My loop works, (gets array from database and shows questions one by one), but it writes all the questions to the page at the same time. DUH. I want it to show one question with a "NEXT" button to show next question. This button clears the first question and writes the next one until they are all done. No grading or anything needed. Is there a way to do this gracefully? I dont know much javascript but looked up innerHTML and see i can update text that way but the PHP loop I have goes so fast it just end up showing the last question with no way to pause it between questions. Can anyone think of a way to do this? My problem is passing the data from page to page to page (I lose the array data) If this is impossible my other thoughts a 1) store current list of Q/A's in cookie (OR) 2) pass Q/A to another page with POSTS (OR) 3)store Q/A's to temporary sql table and use GETS in loop to show each one by one. "testing.php?question=1" 4) can i set a global variable that can pass the data to separate pages? 5)user iFrame so it looks like one page (dont know how) Im leaning to number 3 but want to hear your suggestions. (sorry very new) I'm new at PHP and have a problem. I have a MySql database with lists of students grouped into classrooms. A typical group is shown in the attached screenshot screenshot.docx. I want to be able to select one or more of the names by using the associated checkbox, and upgrade a student or students into a different group as defined in the radio button list also in the screenshot. I have the rudiments of the file attached, but I have absolutely no idea how I can post the array so that the records are updated. Each student has an individual record with a field name userGroup which holds a string nominated by their classroom teacher, such as "year7", "year 8" and so on while they are in one of the several classrooms, but when they leave school this is recorded in a field named noGroup with a value of 0 or 1. I can post further details as required, but it would be great if someone could help me. |
