PHP - Query Order Using Get

This topic has been moved to MySQL Help.

http://www.phpfreaks.com/forums/index.php?topic=312690.0

I am loading notifications from a database table called "notifications" and I am having a little trouble getting them to order in the correct way.

my query I'm using right now:

Code: [Select]
$query = mysql_query("SELECT B.* FROM (SELECT A.* FROM notifications A WHERE A.user_id='$session' AND A.from_id!='$session' ORDER BY A.id ASC ) AS B ORDER BY B.state ASC LIMIT 7");

this works well as far as showing the unread notifications on top, then the read notifications below, however it's not ordering the two sets by ID (which the id auto increments so the higher id number is the newest) from newest on top to the oldest on bottom, still keeping them separated by the unread on top, read on bottom (column name is state for showing whether they're read or not).
The order the notifications are displaying by their ID is:

3
5
2
4
1

when it should be:

5
3
2
4
1

i am printing the dates from the last 30 days in ascending order and then comparing them in my query to print the results. How can I can print the below array in descending order without affecting my query?
Code: [Select]
   
  $thirtydaysago = time() - (30 * 24 * 60 * 60);
 
  $oneday=24 * 60 * 60;
  for($i=0;$i<31;$i++)
  {
     $d[$i]= $thirtydaysago + ($i*$oneday);
echo date('Y-m-d',$d[$i])."<br>";
  }
  for($i=0;$i<31;$i++)
  {
     $postsql=mysql_query("SELECT DATE_FORMAT(FROM_UNIXTIME(dateline), '%Y-%m-%d') AS FmtDate, COUNT(postid) AS PostCnt FROM post " .
              "WHERE dateline < '" . $d[$i+1] . "' AND dateline >= '" . $d[$i] . "' GROUP BY DATE_FORMAT(FROM_UNIXTIME(dateline), '%Y-%m-%d') DESC") or die(mysql_error());
   

   if($postsql_rows=mysql_fetch_assoc($postsql))
   {
    $data_date[$i]["date"]=$postsql_rows['FmtDate'];
$data_postcount[$k][$i]["postcount"]=$postsql_rows['PostCnt'];
   }
 }
 $k++;
 }

Hi everyone. I'm very new into self learning programming. Presently I'm trying to develop a simple basic Robot that would only Place a Market Order every seconds and it will cancel the Order every followed seconds. Using the following library:
https://docs.b2bx.exchange/en/_docs/api-reference.html#private-api

It would place Trade Order at a ( Price = ex.com api * Binance api Aggregate Trades Price)

I have already wrote the api to call for xe.com exchange rate with php 

<?php

$auth = base64_encode("username:password");
$context = stream_context_create([
    "http" => [
        "header" => "Authorization: Basic $auth"
    ]
]);
$homepage = file_get_contents("https://xecdapi.xe.com/v1/convert_from?to=NGN&amount=1.195", false, $context );
$json = json_decode($homepage, TRUE);
foreach ($json as $k=>$to){
    echo $k; // etc
};


?>

And also for the Binance Aggregate Price in JavaScript

 

<script>
var burl = "https://api3.binance.com";

var query = '/api/v3/aggTrades'; 

query += '?symbol=BTCUSDT';

var url = burl + query;

var ourRequest = new XMLHttpRequest();

ourRequest.open('GET',url,true);
ourRequest.onload = function(){
    console.log(ourRequest.responseText);
}
ourRequest.send();
</script>

  My problem  is how to handle these two api responds  and also the functions to use them to place a trade and cancel it.
Please help me out. Thanks in advance on any help.

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!

case "update-delete":
	if(isset($_POST['highlight-purchased'])) 
		{
			// ****** Setup customized query to obtain only items that are checked ******
			$sql = "SELECT * FROM shoplist WHERE";

Here is my code:
// Start MySQL Query for Records
$query = "SELECT codes_update_no_join_1b" .
"SET orig_code_1 = new_code_1,
       orig_code_2 = new_code_2" .
"WHERE concat(orig_code_1, orig_code_2) = concat(old_code_1, old_code_2)";
$results = mysql_query($query) or die(mysql_error());
// End MySQL Query for Records


This query runs perfectly fine when run direct as SQL in phpMyAdmin, but throws this error when running in my script??? Why is this???

Code: [Select]
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '= new_code_1, orig_code_2 = new_code_2WHERE concat(orig_code_1, orig_c' at line 1

If you also have any feedback on my code, please do tell me. I wish to improve my coding base.

Basically when you fill out the register form, it will check for data, then execute the insert query. But for some reason, the query will NOT insert into the database. In the following code below, I left out the field ID. Doesn't work with it anyways, and I'm not sure it makes a difference.

Code:

  Code: [Select]
mysql_query("INSERT INTO servers (username, password, name, type, description, ip, votes, beta) VALUES ($username, $password, $name, $server_type, $description, $ip, 0, 1)");

I was just wondering if it's possible to run a query on data that has been returned from a previous query?  For example, if I do

Code: [Select]
$sql = 'My query';
$rs = mysql_query($sql, $mysql_conn);

Is it then possible to run a second query on this data such as

Code: [Select]
$sql = 'My query';
$secondrs = mysql_query($sql, $rs, $mysql_conn);

Thanks for any help

I'm trying to update every record where one field in a row is less than the other. The code gets each row i'm looking for and sets up the query right, I hope I combined the entire query into one string each query seperated by a ; so it's like
UPDATE `table` SET field2= '1' WHERE field1= '1';UPDATE `table` SET field2= '1' WHERE field1= '2';UPDATE `table` SET field2= '1' WHERE field1= '3';UPDATE `table` SET field2= '1' WHERE field1= '4';UPDATE `table` SET field2= '1' WHERE field1= '5';
this executes properly if i run the query in phpMyAdmin, however when I run the query in PHP, it does nothing... Any advice?

Say I have this query:

site.com?var=1

..I have a form with 'var2' field which submits via get.

Is there a way to produce:

site.com?var=1&var2=formdata

I was hoping there would be a quick way to affix, but can't find any info. Also, the query could sometimes be:

site.com?var2=formdata&var=1

I would have to produce:

site.com?var2=updatedformdata&var=1

Is my only option to further parse the query?

here's the code:

Code: [Select]
$companyName = 'big company';
$address1 = 'big bay #8';
$address2 = 'some big warehouse';
$city = 'big city';
$province = 'AB';
$postalCode = 'T1T0N0';
$phone = '0123456789';
$email2 = 'bigKahuna@bigKahuna.edu';

$query = "INSERT INTO clients (
                   companyName, address1, address2, city, province, postalCode, phone, email)
                 VALUES ( ".
                    $companyName.",".$address1.",".$address2.",".$city.",".$postalCode.",".$phone.",".$email2.")";

$result = mysql_query($query, $connexion);

if ($result)
{
// Success!
echo "Fabulous!  check the DB, we did it! :D<br>";
?>

<pre>
<?php
print_r($result);
?>
</pre>

<?php
} else {
// Fail!
echo"CRAAAAAPP!  something went wrong.  FIX IT!  :P<br>";
echo mysql_error();
}

if (isset($connexion)) { mysql_close($connexion); }
i copied it over from an old *working* file to illustrate how a simple INSERT works.

this is the error i get:

Code: [Select]
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'company,big bay #8,some big warehouse,big city,T1T0N0,0123456789,bigKahuna@bigKa' at  line 4
looks completely valid to me.  all the database table elements are set to VARCHAR(80), so it can't be a space/type issue...

halp! 

WR!

What would be the correct way to close a mysql query?

At current the second query below returns results from the 1st query AND the 2nd query
The 3rd query returns results from the 1st, 2nd and 3rd query.
 etc etc.

At the moment I get somthing returned along the lines of...

QUERY 1 RESULTS

I'm restarting this under a new subject b/c I learned some things after I initially posted and the subject heading is no longer accurate.

What would cause this behavior - when I populate session vars from a MYSQL query, they stick, if I populate them from an MSSQL query, they drop.

It doesn't matter if I get to the next page using a header redirect or a form submit.  I have two session vars I'm loading from a MYSQL query and they remain, the two loaded from MSSQL disappear. 

I have confirmed that all four session vars are loading ok initially and I can echo them out to the page, but when the application moves to next page via redirect or form submit, the two vars loaded from MSSQL are empty. 

Any ideas?

Hello,


I have classes in a database with no set UNIX date, just the day like Wednesday and in two other columns the start and end dates.


I want to be able to order by the day first and then by end_time but php orders the day column by spelling and not the day it holds in chronological order.


Is there anyway to change the query to order the day column as a date?


See the query below?


Code: [Select]
$query = "SELECT * FROM zumba_timetable WHERE end_time>'$current_time' ORDER BY day, end_time ASC LIMIT 0,1";
