PHP - Querying A Second Table Based On 1st Queries Results
hi
I have 2 tables (members & friendship) Members table columns: -------------------------------------------- username | password | email | etc .... -------------------------------------------- Person 1 xxxxxx x@x.com person 2 yyyyyy y@y.com Friendship columns: --------------------------------------- username | friend | status | --------------------------------------- person 1 person 2 friends person 2 person 1 friends person 1 person 3 pending I want to query the friendship table: "SELECT friend FROM friendship WHERE username ='$_SESSION['myusername'];' AND status='friends' " (so its basically getting the user names of anyone who is the logged in users friend) And then use the returned user names to select their data from the members table. Any help much appreciated! ^.^ Similar TutorialsI have three tables: events, orderdetails & orders. First I query orderdetails to find all the records that match the EventID: $query1 = SELECT * FROM orderdetails WHERE EventID = $_SESSION['EventID']; This returns 4 records. These 4 records have a field called DetailOrderID which is the foreign key for orders.OrderID. Next I need to query the results of the first query to find all the records in the orders table that match up. For example: SELECT * from orders where $query1.DetailOrderID = orders.OrderID. How would I go about doing this? I'm head down the temporary table solution but wanted to through this one out for discussion before I invest too much time. I've been trying to fix this piece of script so i can query the results from a database. What i want to do is to display the results from the database like below: Product Heading price Subproduct - $price Each item would have a check box next to them. I have managed to display the items but not the prices. I've looked over the code several times but i'm lost on what i should do. Anyway here's the code, i hope someone here can view it and let me know what i'm doing wrong or what i'm not doing. <?php $get_cats = "SELECT * FROM sub_service WHERE industry='$industry'"; $run_get = mysql_query($get_cats) or die(mysql_error()); $tmp = array(); $x=1; while($rw = mysql_fetch_assoc($run_get)){ if (!array_key_exists($rw['service'],$tmp)) { $tmp[$rw['service']] = array(); } $tmp[$rw['service']][] = $rw['sub_service']; } foreach ($tmp as $service => $items) { ?> <div id="industry_wrapper"> <h2><?php echo $service ?></h2> </div> <div id="select_all_holder"> <div id="select_all_input"> <input type="checkbox" class="toggleElement" name="toggle" onchange="toggleStatus()" /> </div> <div id="select_all_txt"> <p>Select All Services - $</p> </div> </div> <?php echo' <div class="service_holder"> <table width="650" cellpadding="0" cellspacing="5"> '; foreach ($items as $cat) { ?> <tr> <td width="28" align="center"><input type="checkbox" /></td> <td width="605"><p><?php echo $cat ?> - $<?php echo $tmp['price']; ?></p></td> </tr> <?php } echo'</table></div>'; } ?> Hi
I have a form that has a drop-down with a few to choose from, unfortunately I don't get results for some due to the query involved.
Some need the AND channel LIKE '%$channel%'"; and some don't and therefore will not get desired results. So I would like to run two queries one with and one without.
$query = "SELECT * FROM asterisk_cdr WHERE calldate BETWEEN '$calldate' AND '$calldate2' AND clid LIKE '%$clid%' AND channel LIKE '%$channel%'";
Thanks
Hi everyone. I'm a query very similar to the one below with no success. Unfortunately SQLs and joins are not my strong suit. Code: [Select] SELECT f.field1, f.field2, f.field3 FROM fields_table f WHERE f.field1 = SOME_VALUE LEFT JOIN fields_table s ON s.field2 > f.field2 AND s.field3 <= f.field3 LIMIT 1 I would like the first SELECT query to be returned even if there are no matches on the join, also I'd like the second table query to be limited to 1. Is this possible? Could anyone revise the table above to make this work? Thanks! Complete beginner here so just really looking for pointers on where to start. Been doing a bit of bug fixing on one of our sites because the past 3 programmers we've hired have disappeared on us. The big issue I'm looking to solve is the load time of a search. Our website (Love-Rugs) is taking about 6 or 7 seconds to perform a blank search (basically a quick browse) whereas out other site (Little-Persia) takes about a second. It wouldn't be so bad if it was just the initial search but going from one page (only 10 products listed per page) to the next takes the same amount of time. There seems to be an awful lot of queries (around 130-150) on the searches - however - when using some of the search options e.g. type and fabric to refine the search the queries actually stay high but the time to process the results is reduced significantly. I don't really understand why if the queries are still high the search time is much lower unless it's to do with the number of results returned. However this does not explain why Little-Persia (which has far more products on it) takes less time as there would obviously be more results. I realize that without code this isn't easy to answer so I'm just looking to see if someone can point me in the right direction to look at just now. Hello I have a question. I'm trying to perform multiple queries based off the results from a query. Is this possible ? $result = mysql_query("SELECT id FROM sometable"); for each id returned $result1 = mysql_query("SELECT * FROM someothertable WHERE id=result from $result query"); Any help would be GREAT am total newbie to programming, apart from knowing SQL, the thing is i have been given a MYSQL database containing various information about kids diseases and a web interface written in php to create reports from the database that can be accessed via the interface. there are almost 25 different variables that need to be computed in the report, i have written sql queries to compute all these values, but i don't know anything about PHP, if i have all these queries isn't there a way for me to combine all these sql queries to be display results on a webpage and come up with this report without writing PHP code? Thanks for your help very sorry if this is too basic So I'm trying to basically trying to make an "advanced search" function in PHP/mysql that will allow users to search by a number of different options like search by zipcode, username, gender, etc. Now my question is how do I vary my mysql query so that it searches for all these things based on whatever the user inputs? For example, the user might need to search zipcode and username but not gender, but in another case, might need to search username and gender, but not zipcode. Obviously I could just do some if/else statements, but that would be increasingly more difficult as there are more fields. What can I do? Ok, I need some serious help here. I have a jQuery .load method that retrieves a single users name from a database. However... I also need to incorporate error checking into the script that the .load method access, so that, if the user enters a name in the field that is not in the database, it will insert it into the database, and then then pull it back out again to be returned by the ajax call. This is the jQuery that performs the call: Code: [Select] $('#submit').click(function(e) { var user = $('#user').val(); var checkurl = "indexData.php"; $('#username').load(checkurl, 'user=' + user); e.preventDefault(); }); This is the script form indexData.php: Code: [Select] <?php $db = mysql_pconnect('localhost', 'joeme0', 'Galatians2'); if (!$db) { die('Could not connect: ' . mysql_error()); } mysql_select_db('joeme0_brave'); $name = $_POST['name']; $checkQuery = "select name from users where name='$name'"; $checkResult = mysql_query($checkQuery); if ($checkResult > 1) { $insQuery = "insert into users (id, name) values ("", '$name')"; $insResult = mysql_query($insQuery); if ($insResul 0) { $query="select name from users where name='$name'"; $result=mysql_query($query); while($row=mysql_fetch_array($result)) { echo $row['name']; } } else { echo "Cold not insert your name into the database"; } } else { $query="select name from users where name='$name'"; $result=mysql_query($query); while($row=mysql_fetch_array($result)) { echo $row['name']; } } ?> So far I can get it to pull out a name that is manually entered into the database no problem. But I can't get it to insert a name that isn't in the database, and then query the database a second time to pull that same name back out again. The page is pretty simple. The user comes to the page, enters their name in the text field, either clicks the submit button or presses the enter key. The scripts fire off the ajax call to the database, check to see if the name exists, if not enter it and pull it back out (this is where I have the problem), if so, pull it out and display it back on the page. Hi im new to php and I need help making webpage that queries a mysql database based on a 3 check boxes and displays results on the same page or on another page. The table being queried has 4 columns, name, gps, wifi, bluetooth. So for example a row in the table would be like, samsung galaxy s2, yes, yes, yes. The idea is for it to be a website that will display phones according to their features. So the idea is depending on if the boxes were ticked the samsung galaxy would be displayed as a result. So i need some help understanding how to make this. Some1 gave me the code below in attempt to help me (im not sure it works or not) but im not sure how fully use it, ie what pages i need to make and how i create the connection to the mysql database, and how to use the query that they wrote to display the results thanks code: Code: [Select] <form action="?do=filter" method="post"> <table cellspacing="0" cellpadding="3" border="1"> <tr> <td>GPS<input type="checkbox" name="gps" value="checked"></td> <td>Wifi<input type="checkbox" name="wifi" value="checked"></td> <td>Bluetooth<input type="checkbox" name="bluetooth" value="checked"></td> </tr> <tr><td><input type='submit' name='filter' value='Filter'></td></tr> </table> </form> </html> <?php function filterMe($filter){ if(isset($_POST[$filter])){ return "Yes"; }else{ return "No"; } } if(isset($_POST['filter'])){ echo "Gps - " . filterMe('gps'); echo " Wifi - " . filterMe('wifi'); echo " Bluetooth - " . filterMe('bluetooth'); } ?> All you need to do is use a query something like SELECT name,gps,wifi,bluetooth FROM `product` WHERE `gps`='".filterMe('gps')."' AND `wifi`='".filterMe('wifi')."' AND `bluetooth`='".filterMe('bluetooth')."' Hi Guys. Hopefully someone can help me with this...New to coding and pretty lost on this. I have a Mysql database which is displaying results to my webpage with no problems.

I'm trying to pull results from a database based on where the user is located based upon the variables $usr_lat & $usr_lng, and search for by a radius of x amount of miles/km (need to make it optional). I can't seem to find exactly what I'm looking for on google so I thought I'd asked here. Any help would be appreciated.
I'm very new to this and really could use some help. I've got a Web app that has one form that collects data from the user and puts it into a mysql database and has another form that allows the user to select critiera to find records in the database and display them on the page. All this is working just fine, but now that my database is getting more data in it, I want to add functionality to display 10 records on a page with results page navigation links so the user can move forward and backward in the results set. This part is not working and I've put in echo statements to figure out what the code is doing. The problem I'm having is that when the selection critiera pulls more than 10 records from the database, the first page of results is correct per the selection criteria entered by the user on the select form. When the 'next' link is selected to review the second page of results, the query is executed again. But this time the form variables have been reset and the results now contains the entire contents of the db. The start record is set to look at the 11th instance of the results set, so the second page starts with the 11th record in the database instead of the 11th record in the original results set. The original select statement is built by determining which criteria is selected using $_POST against each form variable. How can I retain the form variables or the original select statement so the second execution of the select statement results in the same results set as the first? The other option that may be better is to retain the original results set and avoid re-executing the select statement altogether. But I don't know how to do that either. Any suggestions, code samples or adivice is much appreciated! I have a search form that has a drop down Code: [Select] <select name="radius" id="radius"> <option value="5">5 mi.</option> <option value="10">10 mi.</option> <option value="15">15 mi.</option> <option value="20">20 mi.</option> <option value="50">50 mi.</option> <option value="100">100 mi.</option> </select> I'm trying to limit the results in a foreach loop within what was selected. Meaning, if someone selects 10, results within 10 miles will show The foreach is Code: [Select] foreach ($stores as $k=>$v) { $output = "<h3 style='margin:0;padding:0'><b>".$storeinfo[$k]['MktName']."</b><br>(approx ".$v." miles)</h3>"; $output .= "<p style='margin:0 0 10px 0;padding:0'>".$storeinfo[$k]['LocAddSt']."<br>"; $output .= $storeinfo[$k]['LocAddCity'].", ".$storeinfo[$k]['LocAddState']." ".$storeinfo[$k]['zipcode']."</p>"; print_r($output); } $v being the distance. So I need to show only the results of $v that are less than $r. How would I go about doing this? Right now, $v displays numbers like 5.04, 173.9 and so forth. Can anybody help me out? Thanks in advance. Hi All ,
I have a small table with 4 fields namely Day_ID, Dues, Last_Visit, Points. where Day_ID is an auto-increment field. The table would be as follows:
Day_ID -- Dues --- Last_Visit --- Points.
1 --------- 900 -------- 1/12 -------- 6
2 --------- 700 -------- 4/12 -------- 7
3 --------- 600 -------- 7/12 -------- 5
4 --------- 600 -------- 9/12 -------- 6
5 --------- 600 -------- 10/12 ------- 6
6 --------- 600 -------- 14/12 ------- 6
So this is the record of a person's visit to say a club. The last row indicates the last date of his visit to the club. His points on this date are 6. Based on this point value of 6 in the last row I want to retrieve all the previous BUT adjoining all records that have the same Points i.e. 6.
So my query should retrieve for me, based on the column value of Points of the last row (i.e. Day_ID - 6 ), as follows:
4 --------- 600 -------- 9/12 -------- 6
5 --------- 600 -------- 10/12 ------- 6
6 --------- 600 -------- 14/12 ------- 6
This problem stated above had been completely resolved, thanks to a lot of help from Guru Barand by this following query :-
$query = "SELECT cv.day_id, cv.dues, cv.last_visit, cv.points FROM clubvisit cv WHERE last_visit >= ( SELECT MAX(last_visit) FROM clubvisit WHERE points <> ( SELECT points as lastpoints FROM clubvisit JOIN ( SELECT MAX(last_visit) as last_visit FROM clubvisit ) as latest USING (last_visit) ) )";I am using this and it works perfectly except that now there is a slight change in the table because the criteria for points is now dependent on more than one column cv.points and is more like cv.points1, cv.points2, cv.points3 etc. So now I need to make a selection based on each of these cv.points columns. As of now I can still get the results by running the query multiple times for each of the cv.points columns ( seperately for cv.points1, cv.points2, cv.points3) and it works correctly. However I am wondering if there is a better way to do this in just one go. This not only makes the code repetitive but also since the queries are interconnected, involves the use of transactions which I wish to avoid if possible. The values that I require for each of the cv.point columns is 1. day_id of the previous / old day on which the cv.points value changed from the current day value, and 2. cv.points on that old/ previous day. So for example if the table is as below: Day_ID -- Dues --- Last_Visit --- Points1 --- Points2. 1 --------- 900 -------- 1/12 ----------- 9 ------------ 5 2 --------- 600 -------- 4/12 ----------- 6 ------------ 6 3 --------- 400 -------- 7/12 ----------- 4 ------------ 7 4 --------- 500 -------- 9/12 ----------- 5 ------------ 8 5 --------- 600 -------- 10/12 ---------- 6 ------------ 8 6 --------- 600 -------- 11/12 ---------- 6 ------------ 8 7 --------- 600 -------- 13/12 ---------- 6 ------------ 7 8 --------- 500 -------- 15/12 ---------- 5 ------------ 7 9 --------- 500 -------- 19/12 ---------- 5 ------------ 7 Then I need the following set of values : 1. day_id1 -- Day 7, points1 ---- 6, days_diff1 -- (9-7 = 2) . // Difference between the latest day and day_id1 2. day_id2 -- Day 6, points2 ---- 8, days_diff2 -- (9-6 = 3) 3. day_id3 -- .... and so on for other points. Thanks all ! This is a little confusing so please bear with me. I was thinking of using left.join but couldn't figure out how to implement it properly. I am trying to order all of the results from a table names 'clans' based on how many points the clan has. To calculate the points you have to go into another table 'clanteams' and then loop every team in the clan pulling wins and losses from a row in a specific ladder table. Here is the code i have to calculate the points. Code: [Select] $total[wins] = 0; $total[loss] = 0; $members=mysql_query("SELECT id,clanid,teamid,DATE_FORMAT(datejoined,'%M %d, %Y') FROM clanteams WHERE clanid='$member[id]'"); while(list($id,$clanid,$teamid,$joined)=mysql_fetch_row($members)){ $team=mysql_query("SELECT name,ladderid FROM teams WHERE id='$teamid'"); if(mysql_num_rows($team) == 0) continue; $team=mysql_fetch_array($team); $ladder=mysql_query("SELECT name FROM ladders WHERE id='$team[ladderid]'"); $ladder=mysql_fetch_array($ladder); $linfo=mysql_query("SELECT rank,wins,loss FROM ladder_$team[ladderid] WHERE teamid='$teamid'"); $linfo=mysql_fetch_array($linfo); $total[wins] = $total[wins] + $linfo[wins]; $total[loss] = $total[loss] + $linfo[loss]; } $totalpoints = ($total[wins] * 2) - $total[loss]; So now i want to loop through every row in the clans table, and using the above code oder them by $total points. Ive spent hours wrapping my head around it and still cannot figure it out. Please help. when I do a "SELECT * FROM system_disks WHERE system_id = 'aNumber'" and their is more than one result with that system_id, I get more than one result obviously. I essentially need two results in one row. I've took a screen shot of what it is doing and what I need it to do. The blurred row is a different system_id This is what the while ($row = mysql_fetch_array($query)) is currently doing: This is what I would like it to do: Sorry if this is a dumb question, I've been coding the past 48 hours and my brain is fried Hi guys, I am working with an old script at the moment, there is one page which just will not populate the table results.

If I comment out this line, no errors are produced but the results do not enter the table. Can anyone shed some light on this please, I've spent hours and hours and banging my head against a brick wall would probably be more constructive right now.
