  • PHP & MySQL query value question.

    - by space
    How can I use the first query's id value $row['id'] again after I run a second query inside the while loop statement? To show you what I mean here is a sample code below of what I'm trying to do. I hope I explained it right. Here is the code. $mysqli = mysqli_connect("localhost", "root", "", "sitename"); $dbc = mysqli_query($mysqli,"SELECT users.* FROM users WHERE user_id = 4"); if (!$dbc) { // There was an error...do something about it here... print mysqli_error($mysqli); } while($row = mysqli_fetch_assoc($dbc)) { echo '<div>User: ' . $row['id'] . '</div>'; echo '<div>Link To User' . $row['id'] . '</div>'; $mysqli = mysqli_connect("localhost", "root", "", "sitename"); $dbc2 = mysqli_query($mysqli,"SELECT COUNT(cid) as num FROM comments WHERE comments_id = $row[id]"); if (!$dbc2) { // There was an error...do something about it here... print mysqli_error($mysqli); } else { while($row = mysqli_fetch_array($dbc2)){ $num = $row['num']; } } echo '<div>User ' . $row['id'] . ' Comments# ' . $num . '</div>'; }

  • Performing a MYSQL query based off of $_GET results

    - by Michael N
    When a user clicks an item on my items page, it takes them to blank page template using $_GET to pass the item brand and model through. I'd like to perform another MYSQL query when that user clicks through to populate the blank page with the product details from my database. I'd like to retrieve the single row using the model number (unique ID) to populate the page with the information. I've tried a couple of things but am having a little difficulty. On my blank item page, I have $brand = $_GET['Brand']; $modelnumber = $_GET['ModelNumber']; $query = mysql_query("SELECT * FROM items WHERE `Model Number` = '$modelnumber'"); $results = mysql_fetch_row($query); echo $results; I think having ''s around Model Number is causing troubles, but without them, I get a Warning: mysql_fetch_row() expects parameter 1 to be resource, boolean given error. My database columns looks like Brand | Model Number | Price | Description | Image A few other things I have tried include $query = mysql_query("SELECT * FROM item WHERE Model Number = $_GET['ModelNumber']"); Which gave me a syntax error. I've also tried concatenating the $_GET which gives me a mysql_fetch_row() expects parameter 1 to be resource, boolean given error Which leads me to believe that I'm also going about displaying the results incorrectly. I'm not sure if I need to put it in a where loop like I have with my previous page which displays all items in the database because this is just displaying one.

  • PHP and MySQL - correct way to use mysqli_real_escape_string

    - by TaG
    I was wondering if the code below is the correct way to use mysqli_real_escape_string() when storing users data in a database. Here is the PHP & MySQL code. if (mysqli_num_rows($dbc) == 0) { $mysqli = mysqli_connect("localhost", "root", "", "sitename"); $dbc = mysqli_query($mysqli,"INSERT INTO info (user_id, url) VALUES ('$user_id', 'mysqli_real_escape_string($url)')"); } if ($dbc == TRUE) { $dbc = mysqli_query($mysqli,"UPDATE info SET url = 'mysqli_real_escape_string($url)' WHERE user_id = '$user_id'");

  • Determining difference in timestamps for two values in the same MySQL table

    - by JayRizzo03
    I am relatively new to programming in PHP, so I apologize if this is a rather simple question. I have a MySQL database table called MachineReports that contains the following values: ReportNum(primary key, auto increment), MachineID and Timestamp Here is some example data: |ReportNum | MachineID | Timestamp | |1 | AD3203 | 2012-11-18 06:32:28| |2 | AD3203 | 2012-11-19 04:00:15| |3 | BC4300 | 2012-11-19 04:00:15| What I am attempting to do is find the difference in timestamps in seconds for each machine ID by iterating over each row set. I am getting stuck on the best way to do this, however. Here is the code I've written so far: <?php include '../dbconnect/dbconnect.php'; $machineID=[]; //Get a list of all MachineIDs in the database foreach($dbh->query('SELECT DISTINCT(MachineID) FROM MachineReports') as $row) { array_push($machineID, $row[0]); } for($i=0;$i<count($machineID);$i++){ foreach($dbh->query("SELECT MachineID FROM MachineReports WHERE MachineID='$machineID[$i]' ORDER BY MachineID") as $row) { //code to associate each machineID with two time stamps goes here } } ? This code just lists out the contents of the table row by row. My ultimate goal is to find the difference in timestamps for a certain MachineID. One of the things I've considered is using a multidimensional array in php - using the $machineID as the key and then storing the timestamp inside the array the key points to. However, I'm uncertain how to do that since my query parses row by row. I have quite a few questions. 1) Is this the most efficient way to be doing this? I suspect my database table design may not be the best. 2)What would be the best way to determine the difference in timestamps for a certain machineID? Even just a pointer to a topic that would prompt me to think about this in a different way would be helpful - I'm not afraid to do research. Thanks!

  • mySQL convert varchar to date

    - by Jeff V
    I need to convert a varchar value of 1/9/2011 to a date in mySQL and I want only the month and year. So that I can then use the PERIOD_DIFF function (so I would need the above to be converted to 201101). I've tried various ways using the STR_TO_DATE function: SELECT STR_TO_DATE(CYOApp_oilChangedDate, '%m/%Y') FROM CYO_AppInfo But I get weird results... (for example: 2009-01-00) What am I doing incorrectly?

  • Sorting MySQL table by next due date

    - by Zagga
    Hi folks, I have a MySQL table that stores (amongst other things) a persons date of birth. Is there any way to sort the table so the next due birthday is at the top? I have the date stored in standard yyyy-mm-dd DATE format and seperate year, month and day fields so I can sort it by the first birthday of the year (ORDER BY month, day) but I can't seem to get any further. Any help would be greatly appreciated. Zagga

  • Index a mysql table of 3 integer fields

    - by Doori Bar
    I have a mysql table of 3 integer fields. None of the fields have a unique value - but the three of them combined are unique. When I query this table, I only search by the first field. Which approach is recommended for indexing such table? Having a multiple-field primary key on the 3 fields, or setting an index on the first field, which is not unique? Thanks, Doori Bar
