PHP - Mysql Query To Update Multiple Columns At Once?
I made a small editing system for my news page, and I need to update three columns within my table "announcements" in the database. I tried a method of updating all of them with one MySQL query instead of using three as it just isn't neat. I've searched several methods via google and I've tried all of them, but just can't seem to get it to work. Is this MySQL query correct?
mysql_query("UPDATE announcements SET title = {$title} WHERE id = '$id', content = {$content} WHERE id = '$id', lastmodified = ". date('M-d-Y') ." WHERE id = '$id'"); Similar TutorialsI 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 This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=351561.0 Hi there, This is what I need to do, blow that is the code I have knocked up to do it but it doesn't seem to work. The main problem is the query that matches the atc callsigns to the pilots destinations.. can't fathom it myself. 1. Pull all the records from my database. 2. Assign their unique user id's, callsigns and destinations. 3. Execute a query in which you: SELECT * FROM CLIENTS WHERE (The 'clienttype' = 'ATC') AND match the callsign of the ATC users to the 'planned_destairport' of the 'clienttype' = 'PILOT'. For example if three people are going to Heathrow, then it would return 3 results. 4. Then do a mysql_num_rows of the result. 5. Lastly, execute a query that would update the 'atcarrivals' collumn in the database with the count number using the unique 'cid' as the identifier. All in a loop of course. // Selects all of the ATC Records. $atc_arrivals_selectquery = mysql_query ("SELECT * FROM CLIENTS"); // Starts the loop for fetching the records of the previous query. while($atc_arrivals_row = mysql_fetch_array($atc_arrivals_selectquery)){ // Sets the users cid, planned_destairport and callsign. $atc_cid = $atc_arrivals_row['cid']; $atc_destinations = $atc_arrivals_row['planned_destaiport']; $atc_callysign = $atc_arrivals_row['callsign']; // Searches the database and selects all records where the callsign is LIKE the destination airport. $atc_arrivals_check = mysql_query("SELECT * FROM CLIENTS WHERE clienttype = 'ATC' AND callsign LIKE '%$atc_destinations'"); // Counts previous query results. $atc_arrivals_count = mysql_num_rows($atc_arrivals_check); // Updates the atcarrivals column with the count.. $atc_arrivals_updatequery = mysql_query("UPDATE CLIENTS SET atcarrivals = '$atc_arrivals_count' WHERE cid = '$atc_cid' AND clienttype = 'ATC'"); // End loop. } Concerned columns are these: "cid" - Unique client id. "atcarrivals" - Number of arrivals from count. (This is the problem.) "planned_destairport" - Destination airport of pilot. Usually four letters long. IE. EGLL = Heathrow. Thanks. I have a table called "friends" and 4 columns called: id......friend_1......friend_2.......date I want to retrieve all of the friends of the user that is logged in, so if the table looks like: friend_1.........friend_2 3.........................6 6.........................8 12.......................3 the result if the users id is 3 would be: 6 12 and if the users id was 6 it would be: 3 8 the query I have right now partially works, just note sure how to modify it to get the full result I want. Code: [Select] $get_friends = mysql_query("SELECT * FROM friends WHERE (friend_1='".$session."' OR friend_2='".$session."')"); while($friends = mysql_fetch_array($get_friends)) { print $friends['friend_1']; }with the code above if you use the table I showed above and assumed that $session = 3, the result is: 3 12 but should be: 6 12 hopefully that's pretty straight forward, thanks in advanced. I create a post just now but cannot seem to find it to add to it. Anyhow, I have 2 tables, I need to multiply qty from the one table to the mass from the other to get a total, which I have achieved with this code:
$sql_total_mass = "
SELECT jobs_assembly.assemble_qty, jobs.mass,
(jobs_assembly.assemble_qty * jobs.mass) AS 'sum'
FROM jobs_assembly
LEFT JOIN jobs on jobs_assembly.jobs_id = jobs.id
LEFT JOIN job_names ON jobs.job_names_id = job_names.job_id
WHERE jobs_assembly.assemble_date = '$link_date'
ORDER BY job_names.job_name, jobs.assembly
";
$result_total_mass = mysqli_query($conn, $sql_total_mass);
if (mysqli_num_rows($result_total_mass) > 0) {
while($row_total_mass = mysqli_fetch_assoc($result_total_mass)) {
echo $row_total_mass['sum'].'<br />';
} //while
} //if
Now I need to take all these totals and make a grand total. So basically add all the results from $row_total_mass[‘sum’] together and show it.
I have a search set up to search a table for the text entered in a textbox, I have two columns in the table, one with the first name of people, and the second with their last names, I am wondering how I can search both, so for instance: I type in the search field: Roger Smith in the database it would look like: First_name-----|-----Last_name -------------------|------------------- Roger------------|-------Smith my current query is: Code: [Select] $query = mysql_query("SELECT * FROM users WHERE fname LIKE '%$find%' OR lname LIKE '%$find%'"); But if I type both parts of the name it doesn't return anything. works fine if I just search for "Roger" OR "Smith". Hi ive been stuck for a while now and i just cant get my head around it so if you could help i'd be well chuffed. I'm trying to update multple rows in a table depending upon the results of another. I have a form that enables me to update a table called fleet. Another table called ships is realted to the fleet table as each ship is in a fleet: fleet ----- Fleetname* Location Detected ships ------ ShipID* Fleetname * Shipname The particular fleet i am editing is parsed as a url parameter. I made a query to search for all the ships that are in the fleet i am editing: Code: [Select] $colname_ShipsInfleet = "-1"; if (isset($_GET['recordID'])) { $colname_ShipsInfleet = (get_magic_quotes_gpc()) ? $_GET['recordID'] : addslashes($_GET['recordID']); } mysql_select_db($database_swb, $swb); $query_ShipsInfleet = sprintf("SELECT * FROM ships WHERE FleetName = %s", GetSQLValueString($colname_ShipsInfleet, "text")); $ShipsInfleet = mysql_query($query_ShipsInfleet, $swb) or die(mysql_error()); $row_ShipsInfleet = mysql_fetch_assoc($ShipsInfleet); $totalRows_ShipsInfleet = mysql_num_rows($ShipsInfleet); It searched the ships WHERE the FleetName (which is the primary key of the fleet table) is parsed as a url parameter. The appropriate ship records that are generated i want to use so a field can be updated. For example im updating a fleet record and and setting the location (Planet Name) to a different value. I want the Ship records that are of that particular fleet to update a field (PlanetName) in ship table when the fleet table is updated. Code: [Select] if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) { $updateSQL = sprintf("UPDATE ships WHERE ShipID = $row_ShipsInfleet['ShipID'] SET PlanetName=%s", GetSQLValueString($_POST['select'], "text")); mysql_select_db($database_swb, $swb); $Result1 = mysql_query($updateSQL, $swb) or die(mysql_error()); $updateSQL = sprintf("UPDATE fleet SET PlanetName=%s, Detected=%s, Faction=%s WHERE FleetName=%s", GetSQLValueString($_POST['select'], "text"), GetSQLValueString(isset($_POST['checkbox']) ? "true" : "", "defined","1","0"), GetSQLValueString($_POST['hiddenField2'], "int"), GetSQLValueString($_POST['hiddenField'], "text")); mysql_select_db($database_swb, $swb); $Result1 = mysql_query($updateSQL, $swb) or die(mysql_error()); I'm really not sure how to proceed here so please if you can help me out that would be ace.

If I have to provide more code I will. I am doing an update on a table called countries. Yet my query just will not update the db. Is there anything wrong with this query? mysql_query("UPDATE countries SET country_id = '{$_POST['update_value']}' WHERE country_id = '{$_POST['original_html']}'") or die(mysql_error()); Hi there, I'm having a problem with updating a record with an UPDATE mysql query and then following that query with a SELECT query to get those values just updated. This is what I'm trying to do...I'd like a member to be able to complete a recommended task and upon doing so, go to a page in their back office where they can check off that task as "Completed". This completed task would be recorded in their member record in our database so that when they return to this list, it will remain as "Completed". I'm providing the member with a submit button that will call the same page and then update depending on which task is clicked as complete. Here is my code: Code: [Select] $memberid = $_SESSION['member']; // Check if form has been submitted if(isset($_POST['task_done']) && $_POST['task_submit'] == 'submitted') { $taskvalue = $_POST['task_value']; $query = "UPDATE membertable SET $taskvalue = 'done' WHERE id = $memberid"; $result = mysqli_query($dbc, $query); } $query ="SELECT task1, task2, task3 FROM membertable WHERE id = $memberid"; $result = mysqli_query($dbc, $query); $row = mysqli_fetch_array($result, MYSQLI_ASSOC); $_SESSION['task1'] = $row['task1']; $_SESSION['task2'] = $row['task2']; $_SESSION['task3'] = $row['task3']; ?> <h4>Task List</h4> <table> <form action="" method="post"> <tr> <td>Task 1</td> <td><?php if($_SESSION['task1'] == 'done') {echo '<div>Completed</div>';} else{ echo '<input type="submit" name="task_done" value="Mark As Completed" />';} ?></td> </tr> <input type="hidden" name="task_value" value="task1" /> <input type="hidden" name="task_submit" value="submitted" /> </form> <form action="" method="post"> <tr> <td>Task 1</td> <td><?php if($_SESSION['task1'] == 'done') {echo '<div>Completed</div>';} else{ echo '<input type="submit" name="task_done" value="Mark As Completed" />';} ?></td> </tr> <input type="hidden" name="task_value" value="task2" /> <input type="hidden" name="task_submit" value="submitted" /> </form> <form action="" method="post"> <tr> <td>Task 1</td> <td><?php if($_SESSION['task1'] == 'done') {echo '<div>Completed</div>';} else{ echo '<input type="submit" name="task_done" value="Mark As Completed" />';} ?></td> </tr> <input type="hidden" name="task_value" value="task3" /> <input type="hidden" name="task_submit" value="submitted" /> </form> </table> The problem that I am having is that the database is not updated with the value "done" but after submission, the screen displays "Completed" instead of "Mark As Completed". So the value is being picked up as "done", but that is why I have the SELECT after the UPDATES, so that there is always a current value for whether a task is done or not. Then I refresh and the screen returns the button to Mark As Complete. Also, when I try marking all three tasks as, sometimes all three are updated, sometimes only one or two and again, I leave the page or refresh and the "Marked As Completed" buttons come back. Bizarre. If anyone can tell me where my logic is going wrong, I would appreciate it. I have the following PHP script to update two time/date fields in the database. When i run this the fields are not updated. Can anyone see where i m going wrong. <?php $con = mysql_connect("localhost","dbname","dbpassword"); if (!$con) { die('Could not connect: ' . mysql_error()); } echo 'Connected successfully'; mysql_select_db("my_db", $con); mysql_query("UPDATE msm_content SET created = '2011-01-02 00:00:00', modified = '2011-01-01 00:00:00'"); echo 'Query Updated successfully'; mysql_close($con); ?> Your guidance is much appreciated. Hello, I am trying to pick up php again and just exercising my skills. So I have it so that it fills my form with the values of what I want to edit, and when I click the edit button, it doesn't edit any of the information. When I echo out $result, I get a MYSQL query string that has the same values as the table, so its not getting the new values that are edited. <?php @mysql_connect('localhost', 'root', '') or die("Could not connect to Mysql Server. " . mysql_error()); @mysql_select_db('tutorials') or die("Could not connect to Database. " . mysql_error()); if(isset($_GET['edit'])) { $id = $_GET['edit']; $query = "SELECT `username`, `password` FROM `users` WHERE `id` = '$id'"; $result = mysql_query($query); $row = mysql_fetch_array($result); $name = $row['username']; $password = $row['password']; } if(isset($_POST['edit'])) { $id = $_GET['edit']; $query = "UPDATE `users` SET `username` = '$name', `password` = '$password' WHERE `id` = '$id'"; $result = mysql_query($query); echo $query; if(!$result) { echo mysql_error(); }else{ echo 'updated post'; } } ?> <form method="POST" action="" > <input type="text" name="name" value="<?php echo $name; ?>" /> First name <br /> <input type="text" name="password" value="<?php echo $password; ?>" /> Last name <br /> <input type="submit" name="edit" value="edit" /> </form> I believe it has something to do with the values of $name and $password in the form conflicting with the first if isset and the second if isset. Thanks for any help possible Hi all, I have the following MySQL insert query: Code: [Select] $insert= mysql_query ("INSERT INTO tablename (column1,`".$EXPfields."`) VALUES ('$something','".$EXPvalues."')"); where $EXPfields is an array of table-field-names and $EXPvalues is an array of table-field-values. Now I want to write an equivalent query, but using UPDATE instead of INSERT INTO, but I don't want to write out all the field names/values separately, but again want to use $EXPfields and $EXPvalues. So something like this: Code: [Select] $update = mysql_query ("UPDATE tablename SET (column1,`".$EXPfields."`) = ('$something','".$EXPvalues."') WHERE .... "); Is this possible? If so, what is the proper syntax? Thanks! I've messed around with this for three hours now, and it's driving me batty. I'm running the following Query: mysql_select_db("myDB", $con); $query = "UPDATE mytable SET Name = '$Name', Address = '$Address', City = '$City', State = '$State', Zip = '$Zip', Phone = '$Phone', Website = '$Website', Type = '$Type' WHERE id = '$ID'"; The problem is that it's not updating my database. I've tried everything. I've forced the page to Echo out the variables so that I know they're right. I've run (successful) Delete queries to make sure I'm connecting to the right table. I've forced it to spit out the variables at the end of the Update. Everything I've tried works beautifully... except the Update itself. It doesn't error out or anything- it acts like it's Updating, but the data never changes. I can add to the database and delete from it, but it refuses to let me Update anything. I've looked all over the net, and tried every variation I can find. Nothing works. I also tried this: $query = "UPDATE `testbed` SET `Name`=[$Name],`Address`=[$Address],`City`=[$City],`State`=[$State],`Zip`=[$Zip],`Type`=[$Type],`Phone`=[&Phone],`website`=[$Website] WHERE `ID`=[$ID]"; And $result = mysql_query("UPDATE mytable SET Name = '$Name', Address = '$Address', City = '$City', State = '$State', Zip = '$Zip', Phone = '$Phone', Website = '$Website', Type = '$Type' WHERE id = '$ID'"); None of them do anything at all. Hi guys, I'm trying to query two tables for different data and echo the results that match both tables. Here are the tables I have and the query I'm trying to run.

I need the search to work like this: If there is a value in a form field then the query gets appended with that value but when it gets to the $search_commodity it needs to search the second table (qc_lots) and check for the results. Any results that match have to be matched to the results from the first table (qc_reports) and display (echo) only qc_reports that match to both tables. The only common field is the report_id on the qc_lots table and the id on the qc_reports table. I'm stuck and need some guidance. Can someone help please? I want to have a search product feature, but I would like members to be able to search multiple fields in one go i.e. product_code, Product_name in one MySQL query. The thing is, members have to be logged on, so the query must also only show results relating to that specific member, via the session[member_ID], my current query for listing products for that specific member is : Code: [Select] $sql = "SELECT productId, productCode, image, name, price, stock_level FROM product_inventory WHERE memberr_ID = '" . $_SESSION['SESS_mem_ID'] . "; How would I change the above into a search query to search for productcode, productname and still only show results beloging to this member using the session data ? all help appreciated |
