PHP - Sort List From A Join
Hi,
In my database I have tables for: - Tools (sc_tools) - Categories (sc_categories) - Screencasts (sc_screencasts) In the database there are connections between the mentioned as follows: 1) "sc_tools" has an id: tool_id 2) "sc_categories" has an id: (cat_id) AND a relation to sc_tools (cat_rel_to_tool - which is = tool_id) 3) "sc_screencasts" has an: id (sc_id) AND a relation to sc_tools (sc_rel_to_tool - which is = tool_id) AND a relation to sc_categories (sc_rel_to_cat - which is = sc_id) Ok, so I want to list my data as follows: Tool 1 - Category 1 - - Screencast 1.1 - - Screencast 1.2 - Category 2 - - Screencast 2.1 Tool 2 - Category 1 - - Screencast 1.1 osv. I have been tryin with the JOIN-query: $sql_screencasts = mysql_query("SELECT t.tool_id, t.tool_name, c.cat_id, c.cat_name_dk, s.sc_id, s.sc_desc_dk FROM sc_tools t JOIN sc_categories c ON c.cat_rel_to_tool = t.tool_id JOIN sc_screencasts s ON s.sc_rel_to_cat = c.cat_id "); while ($row_screencasts = mysql_fetch_array($sql_screencasts )) { $tool_name = $row_screencasts["tool_name"]; $cat_name_dk = $row_screencasts["cat_name_dk"]; $sc_desc_dk = $row_screencasts["sc_desc_dk"]; $sc_id = $row_screencasts["sc_id"]; echo "<br><font size=3><b>".$tool_name."</b></font><br>"; echo "- ".$cat_name_dk; echo "<br>- - <a href='view.php?id=".$sc_id."'>".$sc_desc_dk."</a><br>"; } But is lists the data as: Tool 1 - Category 1 - - Screencast 1 Tool 1 - Category 1 - - Screencast 2 etc. - I can't get e GROUP BY working either, so I'm lost right now. Hopefully an expert can help me out? Any help is highly appreciated! Similar Tutorialsi have list of movies A to Z in array i can do simple sort but i want them to sort in grouping like this A [movie name], [movie name], [movie name], [movie name], B [movie name] [movie name] [movie name] [movie name] [movie name] C [movie name] [movie name] [movie name] [movie name] D [movie name] [movie name] [movie name] [movie name] and go on all movies name will be links but A,B,C,D will be remain simple how can i do this i wanna show list like this see this website please visit http://mp3hungama.com/music/genre_albums.php?id=3 thanks Say I have a column in a MySQL database, that contains the following data (each piece of data is in its own row, as stored as a string): 16b 166 13A 13a 4 402c A66 A66b Currently the list sorts as follows: A66 A66b 13A 13a 16b 166 4 402c I need it to sort as follows: A66 A66b 4 13a 13A 16b 166 402c So that any strings that start with a letter are first, followed by numbers in numerical order, with lower case letters coming before upper case letters. This is a huge issue on my website, which has a database of over 35k such numbers, split up into lists. I can't get these sorted properly. At least it would be nice to sort as follows: 1 4 100 344 Instead of 1 100 344 4 Know what I mean? I know that this is complicated, because the variables are strings and not numbers, but is there an easy way to do this? Hi All i am wanting a column list like this http://extensions.joomla.org/extensions basically the database is set up as (id, category, parent) I want the parent to group the category section and list like the the joomla example in three columns search various threads throughout the internet but none seem to cover this entirely can any one please help????? This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=308855.0 Hi, In my mysql database i have a text input option, in the registration form and edit my details form i have a multiple select dropdown list, which user selects options to populate the text input box, which ultimately populates the text field in the mysql database. All works perfectly. The dropdownlist consists of 3 parts <optgroups> first is current selection (what is the usesr current selection)works fine, The second <optgroup> is existing words, what words we(the site) have given as options, and the third <optgroup> is the words that others have used. This is where im having a small problem. Because its a text field when i call the data from the database, it calls the entire text box as a single option in my select list.. I want to break the words in the text field (at the comma) and have them listed each one as an option in the select list. Example what i need: Words in text box:(my input allows the "comma") word1, word2, word3, word4, word5, word6, How i want them called/displayed: <option value=\"word1\">word1</option> <option value=\"word2\">word2</option> <option value=\"word3\">word3</option> <option value=\"word4\">word4</option> <option value=\"word5\">word5</option> <option value=\"word6\">word6</option> here's my code: $query = "SELECT allwords FROM #__functions_experience WHERE profile_id = '".(int)$profileId."' LIMIT 1"; $original_functionsexperience =doSelectSql($query,1); $query = "SELECT allwords FROM #__functions_experience WHERE profile_id = '".(int)$profileId."'

Thank you in advance for help , if is possible Im currently working on a new feature called 'Request Player'. Basically what this does is allows managers to request players within their club for a upcoming fixture. There a multiple teams within a club (Senior As, Senior Bs, Colts U21s). Each team is controlled by a manager. And then they can add players as they need. Anyway, I'm having problems with the sql JOIN. I have currently got this: $check = "SELECT u.* FROM users AS u LEFT JOIN requests AS r ON (u.id = r.player_id) WHERE (u.id = r.player_id)"; I have got two tables. users - all the managers and players. requests - all the requests the managers make to other teams within their club. In the request table i have got this: id player_id - the players that has been requested. fixture_id - the fixture the manager wants to have that player for. accepted - if he has been accepted or not. This comes later on. At the moment i have got it working so that it inserts this data, although the code is working but i want to have a mysql query that checks if a manager has any incoming requests from other teams within the club. BUT only request that has been made to his team.... Could someone please help me out? I'm trying to figure out the best way to do this if I'm doing it right with my for loop.

I am hopping someone can help me sort out a query.
I have two tables, one table is a players table, and a second table is a player_vitals data that stores heights and weight changes. I want to list all the players showing the latest height and weight change.
this query will not fetch the latest height and weight
SELECT a.player_id, a.player_first_name,a.player_last_name, b.player_height, b.player_weight Hi I want to know I can select which ID I get from an inner join? Not sure If I should post here or in the MYSQL forum, but as it's using OOP I posted here. Code: [Select] $sql = "SELECT * FROM area_county INNER JOIN area_country "; $sql .= "ON area_county.country_id = area_country.id "; $sql .= "ORDER BY area_country.country, area_county.county ASC "; $sql .= "LIMIT {$per_page} "; $sql .= "OFFSET {$pagination->offset()}"; $list = Area_county::find_by_sql($sql); foreach($list as $lists){ $ID = $lists->id; $country_id = $lists->country_id; $county = ucwords($lists->county); $country = ucwords($lists->country); echo $ID; } I want it to show the ID of the county, NOT the id of the country. both tables in the database have the ID column called id. I know this can be done, but not to sure how. Thanks Not sure if it is because it is too early in the morning but I am having a problem. Code: [Select] $mpid = # $query = "SELECT table1.title, table2.* ". "FROM table1, table2 ". "WHERE table1.mpid = table2.mpid"; How do I only show the info from the 2 tables where mpid=# I'm trying to pull from my database every spell or attack that is equal to `All`, but it doesn't seem to be working. All it is doing is pulling all the spells, regardless of class = `All`, and also 0 of the attacks. It should be producing a single attack that is = to `All` as no spells are = `All`. Any help would be greatly appreciated! Thanks! (This is my first attempt at a JOIN statement...) $query = "SELECT attacks.id, attacks.name, attacks.price, attacks.class, attacks.descript, spells.id, spells.name, spells.price, spells.class, spells.descript ". "FROM attacks, spells ". "WHERE attacks.class = 'All' || spells.class = 'All' order by attacks.name, spells.name asc"; I'm an amateur PHP/mySQL person, trying to learn some more things, and I've hit a snag trying to do something I haven't done before. Okay, here's what I'm trying to do. I have 3 tables: Items (which includes `id` as the primary key) and a TON of information about each item. Shop (which includes `id` as the primary key) and shop name and location. Sale which has shop_id and item_id. So, what I'm trying to do is have a form where someone can input in an item name and a shop name and have that item then added to the shop. This is where the Sale table comes into play too, as that's going to house each of the items and what shop it's in. I currently have the following queries: $query5 = $db->execute("SELECT id FROM items LEFT JOIN sale ON items.id=sale.item_id"); $query6 = $db->execute("SELECT id FROM shop LEFT JOIN sale ON shop.id=sale.shop_id"); I have the following form: if ($name == "") { $errors++; $errorlist .= "Name is required.<br />"; } if ($location == "" ) { $errors++; $errorlist .= "Location is required.<br />"; } if (!isitem($itemname)) die("That item does not exist."); } if ($errors == 0) { $query = doquery("INSERT INTO `sale` SET `item_id`=`$item`"); admindisplay("New Item Added.","Add Items"); $page = <<<END <b><u>Add Item</u></b><br /><br /> <form action="create_shop.php?do=additem" method="post"> <table width="90%"> <tr><td width="20%">Name:</td><td><input type="text" name="itemname" size="30" maxlength="255" value="" />**Be sure the item is already in the database and matches it IDENTICALLY.</td></tr> <tr><td width="20%">Location:</td><td><input type="text" name="location" size="30" maxlength="55" value="" /><br /><span class="small">Where is the item obtained (unique shop name, please!)</span></td></tr> </table> <input type="submit" name="submit" value="Submit" /> <input type="reset" name="reset" value="Reset" /> </form> What next steps do I need to take?

Hi, I use the following code to create a select menu from an array of options stored in LISTS.php: include 'LISTS.php'; print('<select id="from" name="from">'); foreach ($langList as $lang) {printf('<option %s>%s</option>', ($from1 == $lang ? 'selected="selected"' : ''), $lang); } echo '</select>'; where LISTS.php includes the following: $langList = array(' ','English', 'French', 'German', 'Dutch', 'Spanish'); This works great, but now I want to do something similar with a checkbox list, where each checkbox has an associated 'onchange' javascript function and I'm getting pretty stuck. My checkbox list is of the following form: Code: [Select] <html> <ul style="height: 95px; overflow: auto; width: 200px; border: 1px solid #480091; list-style-type: none; margin: 0; padding: 0;"> <li id="li1b"><label for="chk1b"><input name="chk1b" id="chk1b" type="checkbox" onchange="function1('chk1b','li1b')">Option1</label></li> <li id="li2b"><label for="chk2b"><input name="chk2b" id="chk2b" type="checkbox" onchange="function1('chk2b','li2b')">Option2</label></li> //etc. </ul> </html> What I want to do is have 'Option1', 'Option2', etc. stored in an array in LISTS.php and have a PHP script that populates the checkbox list accordingly, in a similar manner to my select menu above. I can't work out how to get the ID of the next <li> and the next <input> in the list to go up by one each time, e.g. 'li1b' then 'li2b', 'li3b', etc. Could someone pls help me out? Thanks! Hi, Been looking for a little while on this problem, but can't seem to find a solution. Ok, so I have two tables, gallery & users Gallery contains images, image info etc. Users contains usernames, emails etc. In users there is a 'photo' column, which references to an ID in the gallery table. This is so each user can have a 'profile' image from a bank of images stored in gallery. What i'm trying to do is have a query that will output all of the images, and then show the usernames of assigned to each photo if there is one. Heres what i've got: Code: [Select] $result = mysql_query("SELECT *,COUNT(photo) AS usercount FROM gallery LEFT JOIN users ON gallery.img_id=users.photo GROUP BY img_id ORDER BY date_uploaded ASC"); Its all fine, and displays the username, though if there are multiple users using the same photo, it only shows one username. However, when displaying 'usercount', it will show that there are 2+ or whatever. Short of nesting queries within other loops, is there an alternative solution?? Thanks! Edd I need to get the friends password and insert it into the table so the friend can delete it later can some one help me do a table join <?php //include the connect script include "../../../../connect.php"; //Post variables from flash $username = $_POST['username']; $password = $_POST['password']; $status = $_POST['status']; $friend = $_POST['friend']; $username = stripslashes($username); $password = stripslashes($password); $status = stripslashes($status); $friend = stripslashes($friend); $username = mysql_real_escape_string($username); $password = mysql_real_escape_string($password); $status = mysql_real_escape_string($status); $friend = mysql_real_escape_string($friend); $sql = mysql_query("SELECT * FROM user_declined_list WHERE username = '$username' and password = '$password' and friend = '$friend' and status ='$status'"); $rows = mysql_num_rows($sql); $your_username=$rows['username']; if($rows > 0) { echo "&msgTextFriendShipRejected= RESEND NEW FRIEND REQUEST SUCCESSFULLY!"; // ok they are now our friend but we are not thier friend so lets insert the friendship in reverse and set the status to 1 on both ends // Problem i see is this if the user wishs to remove the friend later he will neen his password set to delete from this table. // so i need to do a join table again where friend password gets inserted here.. $insertnewfriend = mysql_query("INSERT INTO user_friends_list (username,password,friend,status) VALUES ('$friend','$password','$username','0')") or die(mysql_error()); //ok lets update the request and set the friend to be a friend becuase we said yes be my friend. $deleteuserfriend = mysql_query("DELETE FROM user_declined_list WHERE username = '$username' and password = '$password' and friend = '$friend' and status ='0'"); return; } ?> I am using the following sql code to display a stream of statuses, I have the username/profile picture/status/likes working but I am now stuck on comments.
SELECT s.*, u.*, c.*, COUNT(l.likes_location_id) AS likeCount FROM stream AS s LEFT JOIN users as u ON (u.users_username = s.stream_username) LEFT JOIN comments AS c ON ( c.comments_location_id = s.stream_id ) LEFT JOIN likes AS l ON ( l.likes_location_id = s.stream_id ) GROUP BY s.stream_id ORDER BY s.stream_id DESC LIMIT 50If a status has multiple comments the results only shows the first comment that was made. How can I get it to include all of them? Also, how would I include this in the PHP loop, without having another loop? Thanks, Edited by slj90, 06 January 2015 - 08:56 PM.
