As part of my User Profile, I have a series of open-ended questions that Members can answer, e.g...
Quote

1.) Why did you start your own business?
2.) If you could offer one piece of advice to other entrepreneurs, what would it be?
:
10.) How do you compete against large corporations?



I was leaning towards creating a many-to-many relationship like this...

member -||---------0<- answer ->0---------||- question


From a database standpoint this works great, HOWEVER, I just realized a big problem...

If run this query...

Code: [Select]
SELECT response
FROM answer
WHERE member_id = 1;
...then I would get TEN RECORDS back and I don't know of any way to maps those to the 10 Text Boxes on the "My Thoughts" page?!

(It would be a real PITA to have to create 10 separate Prepared Queries in PHP - one for each Field - to fill out my page?!)

So, is there a way to keep my table structure, but push the 10 records from above into 10 separate variables so I would have something like $response1, $response2,... $response10 ??

Thanks,


Debbie

Hi,   I am a bit of a MYSQL newbie so please bear with me. I have a database created about football/soccer stats. The database at the moment contains the following tables but more maybe added:   Players Clubs Seasons Competitions   I will create php pages for these tables that add, edit and delete records for each. But the problem I can't get my head around is how to add a record that uses data from other tables, for example we would add a...   player -> club-season-competition   Lets say we want create a player called 'Joe Bloggs' and want to add his details, we need somehow for the page to display an option for club, season and competition. Maybe they can be drop down boxes but how does one fill those drop down boxes with records that are already added in the database for each table?   Thanks

Hey,
Im needing some help with an update form that I have created using PHP/MySQL. Basically the form is working great (updating records, retrieving records and showing errors) but there is a problem with the errors.

If there are no errors and I edit the existing text input values, the database updates fine. However if I edit the existing text input values and there is an error, the edited input values dont save, they revert back to the values of the database.

I understand why this is happening, its because the text inputs are set to show the values of the database so if i edit the existing values and an error occurs or the page is refreshed, the values revert back to the database values. However id like it so that if any text in the text field have been edited and an error occurs, the text stays to how it is until the user by passes any errors and then the database is updated.

Hopefully this makes sense. I have attached the php page just incase anybody wants to look into it but any help would be much appreciated!

Also, im not looking for someone to just to fix this for me but if someone knows my problem and can guide me in the right direction, that would be great.

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 !

I am having trouble showing reports for a given date range. Currently if I specify something like 11/03/2010 to 11/05/2010 I get results for all years within that month and day such as I may get results for 11/03/2008 11/03/2009 11/03/2010 11/04/2008 11/04/2009 11/04/2010 11/05/2008 11/05/2009 11/05/2010.
I am using the following code
$result = mysql_query("SELECT * FROM report WHERE date>='$date_begin' and date<='$date_end' ORDER BY 'date'",$db);

I use the following format in my date feild mm/dd/yyyy

My script is finally working as intended, but I want to add some additional data results.

I am trying to resolve how I can display a count of ONLY the records updated by my query:

// START :: Query to replace matches
mysql_query("UPDATE orig_codes_1a AS a
      JOIN old_and_new_codes_1a AS b ON concat(a.orig_code_1, a.orig_code_2) = concat(b.old_code_1, b.old_code_2)
   SET a.orig_code_1 = b.new_code_1,
                           a.orig_code_2 = b.new_code_2") or die(mysql_error());
// END :: Query to replace matches


In this query I count ALL records selection:


// START :: Create query to be displayed as final results of original codes table.
$result = mysql_query("SELECT * FROM orig_codes_1a") 
or die(mysql_error());  

I want to display a count on this part of the query:

....concat(a.orig_code_1, a.orig_code_2) = concat(b.old_code_1, b.old_code_2)....

hi i am trying to use a query like this
SELECT *
FROM `fares`
WHERE `KMS` >=201
LIMIT 0 , 30

which pops up a databse list of 30 rows which looks something like the one below
KMS    SL_AD    SL_CH
205    122            120
210    124      120
215    125     120
220    127     121
225    128     122

all i want to do is somehow sort and get only the first row(205   122    120) in my php program/

Thanks in advance

Hi,

My company has 240+ locations and as such some users (general managers) cover multiple sites.  When I run a query to pull user information, when the user has multiple sites to his or her name, its adds the second / third sites to the next columns, rather than wrapping it inside the same table cell.  It also works the opposite way, if a piece of data is missing in the database and is blank, its pull the following columns in.  Both cases mess up the table and formatting.  I'm extremely new to any kind of programming and maybe this isn't the forum for this question but figured I'd give it a chance since I'm stuck.

The HTML/PHP code is below:

<table id="datatables-column-search-select-inputs" class="table table-striped" style="width:100%">

                                        <thead>

                                            <tr>

Hi all

I am having some problems with the logic behind a simple idea.

Basically I have a list which returns the names of players from a json request, what I simply want to do is for the user to click on the name which then activates it, so basically they can then run a command directed at that name, so something like

Code: [Select]
Names
a
b
c[onlick select]
d

Action
Ban

Thanks

Hi, this is the first time I've asked for some help from a forum. I guess this code has sort of got me stumped.

So, I have a system where a user can enter a number. The number goes into a mysql database. A random number is also generated and it is added into another column.

So, I want users to be able to delete the number using the random number. I've shown it to them, and I need help working my delete script.
Code: [Select]
<?php
$con = mysql_connect("localhost","","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("a8784hos_adopts", $con);
$adopt = $_POST['adoptid'];
$uniquecode = $_POST['uniquecode'];
$result = mysql_query("SELECT uniquecode, id FROM id WHERE id='$adopt'");
mysql_fetch_array($result);
if (($adopt == $row['id']) || ($uniquecode == $row['uniquecode'])){
mysql_query("DELETE FROM id WHERE id='$adopt'");
echo 'Done! <br/><br/><a href="tester.php">Go back....</a>';
}
else {
echo 'Bad unique code. <br/><br/><a href="tester.php">Go back....</a>';
}
?>

So, the random number is uniquecode in the database, and the number is id. However, when I try this code, it always tell me I have a bad unique code. What am I doing wrong?

Thanks.

Error:
Code: [Select]
No error, Im have trouble Having This Loop Select Only 2 Uploads At a Time.
Code:
Code: [Select]

Hi guys,

essentially, I have very limited knowledge with mysql and have hit a brick wall.

The row that I am trying to select is the following:


Now, I am trying to use the following script to achieve that:

Quote

$query = "SELECT meta_value FROM wp_usermeta WHERE user_id='$id' & meta_key='simple_local_avatar'";


The $id is being passed as 1 from a cookie, and I know for sure that thats working properly, but I cant figure out the coding to select it correctly.

I need the script to search for the ID of the user & then user the simple_user_avatar to find the right entry.

Please someone cast your knowledge and help me out!

Oh, little adendum.

All that happens when the script runs is that the first row of the table is called out, which is:
