PHP - Query: Select Email From Table Where Id = 'any From Array'

I want to make a table for each paddler_id (Field) which exists into pushup Database

My code for paddler_id = 1 is


require "../sql.php";

$result = mysql_query("EXPLAIN pushup");
$r = mysql_query("SELECT * FROM paddlerinfo t1 LEFT JOIN pushup t2 on t2.paddler_id=t1.id LEFT JOIN practicedate t3 on t3.practice=t2.practice_id ORDER BY t1.firstname ASC ");
$r1 = mysql_query("SELECT * FROM pushup  where paddler_id =1 ORDER BY practice_id ASC ");

echo "<table width='30%' border='1' cellpadding='0' cellspacing='0' style='font-family: monospace'>";
echo "<tr>";
echo "<td>DATE</td>";
while ($row = mysql_fetch_array($result)) {

if (in_array($row["Field"], array("paddler_id", "practice_id", "p_id"))) continue;

echo "<td>",($row["Field"]), "</td>";
}
echo "</tr>";

while (($data = mysql_fetch_array($r1, MYSQL_ASSOC)) !== FALSE) {
   unset($data["p_id"],$data["paddler_id"]);
echo "<tr>";
   foreach ($data as $k => $v) { 
echo "<td>";
      echo"$v";
echo "</td>";
}

echo "</tr>";
}


echo "</table>";

mysql_free_result($result);
mysql_free_result($r);
mysql_free_result($r1);
mysql_close();



The problem is on line $r1 = mysql_query("SELECT * FROM pushup  where paddler_id =1 ORDER BY practice_id ASC ");
I want to put something which makes it paddler_id = X where x = 2,3,4,5... and x exists in database and do not print twice the x (because that database may have rows where x = same id


How do i do that??

Hello all,   Based on the suggestion of you wonderful folks here, I went away for a few days (to learn about PDO and Prepared Statements) in order to replace the MySQLi commands in my code. That's gone pretty well thus far...with me having learnt and successfully replaced most of my "bad" code with elegant, SQL-Injection-proof code (or so I hope).   The one-and-only problem I'm having (for now at least) is that I'm having trouble understanding how to execute an UPDATE query within the resultset of a SELECT query (using PDO and prepared statements, of course).   Let me explain (my scenario), and since a picture speaks a thousand words I've also inlcuded a screenshot to show you guys my setup:   In my table I have two columns (which are essentially flags i.e. Y/N), one for "items alreay purchased" and the other for "items to be purchased later". The first flag, if/when set ON (Y) will highlight row(s) in red...and the second flag will highlight row(s) in blue (when set ON).   I initially had four buttons, two each for setting the flags/columns to "Y", and another two to reverse the columns/flags to "N". That was when I had my delete functionality as a separate operation on a separate tab/list item, and that was fine.   Now that I've realized I can include both operations (update and delete) on just the one tab, I've also figured it would be better to pare down those four buttons (into just two), and set them up as a toggle feature i.e. if the value is currently "Y" then the button will set it to "N", and vice versa.   So, looking at my attached picture, if a person selects (using the checkboxes) the first four rows and clicks the first button (labeled "Toggle selected items as Purchased/Not Purchased") then the following must happen:   1. The purchased_flag for rows # 2 and 4 must be switched OFF (set to N)...so they will no longer be highlighted in red. 2. The purchased_flag for row # 3 must be switched ON (set to Y)...so that row will now be highlighted in red. 3. Nothing must be done to rows # 1 and 5 since: a) row 5 was not selected/checked to begin with, and b) row # 1 has its purchase_later_flag set ON (to Y), so it must be skipped over.   Looking at my code below, I'm guessing (and here's where I need the help) that there's something wrong in the code within the section that says "/*** loop through the results/collection of checked items ***/". I've probably made it more complex than it should be, and that's due to the fact that I have no idea what I'm doing (or rather, how I should be doing it), and this has driven me insane for the last 2 days...which prompted me to "throw in the towel" and seek the help of you very helpful and intellegent folks. BTW, I am a newbie at this, so if I could be provided the exact code, that would be most wonderful, and much highly appreciated.   Thanks to you folks, I'm feeling real good (with a great sense of achievement) after having come here and got the great advice to learn PDO and prepared statements.   Just this one nasty little hurdle is stopping me from getting to "end-of-job" on my very first WebApp. BTW, sorry about the long post...this is the best/only way I could clearly explaing my situation.   Cheers guys!

ok, so I need to know how I can perform an operation of $total equaling $price1 + $price2 etc.... if they are not empty in the database............... does this make sense?

I have this code below:

Code: [Select]
members_count <= ".$diff." || members_count >= ".$defmemcount."
My test says $diff = 6 and $defmemcount = 11, members_count = 14

So how come this returns as if members_count isn't less or equal to 6 OR higher or equal to 11?

i am unable to select total_comment from mysql table related to each post..   For detail information check http://stackoverflow...-query-in-mysql

Hi, Everyone! This my first time posting here. Anyways, I've been having problem getting the correct data from my database. I want to select the total_on/off_hours,exposure,plate_number, and terminal_status. But when I select the terminal_status, there are duplicates, I already used the DISTINCT function. It's a little hard to explain so, I'll just show you.   Here's a screen cap of my code trying to get just the terminal_status       What's the problem? What should I do? Any suggestions/help will be much appreciated.

I have 2 queries that I want to join together to make one row  

Hi there I am new to this forum and not much of a php expert. I hope you can assist me. My problem is as follows: I have a column consisting of several values (in this case: sceience, art, humanistics and music) I would like to use the following mysqli query in order to count the appearances of each value in this column:     $query = "SELECT SUM (IF(department = 'science', 1, 0)) AS science, SUM(IF(department = 'art', 1, 0))-> AS art FROM new2"   I have tried lots of ways to loop the results but couldn't get the it working. Can anyone suggest any idea?   Thanks   Hanan

Hi,

i'm trying to select some entries from my DB, i don't quite understand what's the problem here, i'm using this:

Code: [Select]
//Customers Online
$query = "SELECT COUNT(*) as Anzahl FROM customers WHERE status = 1";
$queryerg = mysql_query($query) OR die(mysql_error());
while($row = mysql_fetch_array($queryerg)){
  $customers_online = $row[0];
}
Which works fine, now i want to select by country and i'm doing this:

Code: [Select]
//Customers DE
   $query = "SELECT COUNT(*) as Anzahl FROM customers WHERE country = 'de'";
   $queryerg = mysql_query($query) OR die(mysql_error());
   while($row = mysql_fetch_array($queryerg)){
     $customers_de = $row[0];
   }
Which doesn't work? If i print / echo $customers_de i just get a blank value, not even 0 or anything just blank.

Any help ?

Hello there,

Having a nightmare here.  It feels like what I need to do is really easy but I just can't get it to work.  I have a table called "groups2" that holds a unique id and the name of an activity.

I already have a query that finds the users selected groups using a while loop but I also want to show how many other members are in that group by counting the number of times the activity comes up or the id comes up.  I don't know whether I need 2 while loops nested or what but I get the error

Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource on line 32 which is highlighted.

Can anyone help.  I am no expert at php and still learning so some advice or example code would be great.


$result = mysql_query("SELECT * FROM groups2 WHERE L_ID = ". $_SESSION['member_ID'] .";");
$data = mysql_query("SELECT COUNT('name') AS num FROM groups2 WHERE name = " . $row['name'] . "");
$count = mysql_fetch_assoc($data);
$numbers = $count['num'];
while ( $row = mysql_fetch_assoc($result) ) {
echo("<tr>
<td><font face='Arial, Helvetica, sans-serif' size='3'><strong>" . $row["name"] . "</strong></font></td>
</tr><tr>
<td><font face='Arial, Helvetica, sans-serif' size='1' color='#0000FF'><strong>Members (" . $numbers . ")</strong></font></td>
</tr><tr>
<td><hr width=95%><br></td>
</tr>");
}

Code: [Select]
$DB->query("SELECT SUM(amount)  FROM gold_logs WHERE  from_id = {$ibforums->member['id']} GROUP BY from_id");
   $data = $DB->fetch_row();
Okay, then I echo out
Code: [Select]
{$data['SUM(amount)']}
but I want to select the sum(amount) from "to_id"  ALSO! how can I add that into the query I dont  want to use 2 queries, thanks

Hi

I need some help. I want to send an email to user to inform them about their next appointment date but I don't know how to do the query.
My database look something like this:
id     |  name     |   email     |   contact_no     |   appointment_date
1         Jon            jon@abc.com     12345678      24/12/2011
The appointment date is added in by user so it will keep updating to the latest date.

<?php
include 'config.php';

$sql = executeSelectQuery($MYSQL);

if($sql){
$to = $_POST ['email'];
$subject = "Appointment Date";
$message = "Hello! Please be informed that your next appointment is on $appointment_date";
$from = "123@abc.com";
$headers = "From: $from";
$sent = mail($to,$subject,$message,$headers);

if ($sent){
    $statusMessage = "Mail Successfully Sent.";
}else{
    $statusMessage = "Mail Unsuccessfully Sent";
}

?>

Please kindly help.

Thanks

So I'm querying my database to add the results (mapID's) into a PHP array.
The MySQL query I used in the below code would usually return 10 values (only 10 mapID's in the database)

Code: [Select]
while($data = mysql_fetch_array(mysql_query("SELECT mapID FROM maps"))){
$sqlsearchdata[] = $data['mapID'];
}
Instead the page takes ages to load then gives this error:
Quote

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 16 bytes)

It says the error begins on the first line of the above code. I'm assuming this is not the right way to add the value from the MySQL array into a normal PHP array.

Can anyone help me?
