PHP - Mysql_fetch_array Error On Select Query
I'm trying to figure out some pagination on a left joined query, and not having any luck. The query seems to be pulling the entire database, so I went into the query's WHERE and added the table name "descriptors." Now I'm getting this error with the below query: Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /data/21/2/40/160/2040975/user/2235577/htdocs/leafsearch4.php on line 35
also: Unknown column 'descriptors.leaf_shape' in 'where clause' I thought this was syntax, but maybe I'm missing something. Code: [Select] $query = "SELECT COUNT(*) as num FROM descriptors LEFT JOIN plantae ON (descriptors.plant_id = plantae.plant_name) WHERE `descriptors.leaf_shape` LIKE '%$select1%' AND `descriptors.leaf_venation` LIKE '%$select3%' AND `descriptors.leaf_margin` LIKE '%$select4%'"; $total_pages = mysql_fetch_array(mysql_query($query)); Similar Tutorialswell, i tried to fetch field from my database using the following code: Code: [Select] $result=mysql_query("SELECT * FROM Persons WHERE username='$myusername'" ); while($row = mysql_fetch_row($result)) now that gives me following error: Code: [Select] Warning: mysql_fetch_row() expects parameter 1 to be resource, boolean given in.. Hi guys! I inputted text into the field 'TSuperQuestion' of my table. Now I am trying to echo that text.

Thanks 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!

This is a new error for me. I tried looking through some older posts and so far nothing had fixed it and thus I am stumped. Any idea what could be throwing this error? Code: [Select] <table> <?php //open DB connection include 'dbconn.php'; $sql = "select * tbl_test"; $result = mysql_query($sql,$conn); print $sql; while ($row = mysql_fetch_array($result)){ $status = $row['status']; $space = $row['spacename']; if ($status=="reserved") { echo <<<END <tr> <td style="background-color:#F00; color:#FFF;" align="center">Reserved</td> </tr> END; } else { echo <<<END <tr> <td align="center">$space</td> </tr> END; } } ?> </table> I have this search script, that finds a username in a table and displays it. <form name="search" method="post" action="<?=$PHP_SELF?>"> Search: <input type="text" name="username" /> <input type="hidden" name="searching" value="yes" /> <input type="submit" name="search" value="Search" /> </form> <? //This is only displayed if they have submitted the form $searching = $_POST['searching']; $find = $_POST['username']; if ($searching =="yes") { echo "<h2>Results</h2><p>"; //If they did not enter a search term we give them an error if ($find == "") { echo "<p>You forgot to enter a search term"; exit; } // Otherwise we connect to our Database // We preform a bit of filtering $find = strtoupper($find); $find = strip_tags($find); $find = trim ($find); //Now we search for our search term, in the field the user specified $data = mysql_query("SELECT username FROM users WHERE upper($find) LIKE'%$find%'"); //And we display the results while($result = mysql_fetch_array( $data )) { echo $result['username']; echo "<br>"; echo "<br>"; } //This counts the number or results - and if there wasn't any it gives them a little message explaining that $anymatches= mysql_num_rows ($data); if ($anymatches == 0) { echo "Sorry, but we can not find an entry to match your query<br><br>"; } //And we remind them what they searched for echo "<b>Searched For:</b> " .$find; } ?> For some reason it does not work and gives this message: [b]Warning[/b]: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in [b]C:\Program Files\EasyPHP5.2.10\www\yanille\users.php[/b] on line [b]153[/b] Error: Unknown column 'MI' in 'where clause' The reason it says MI is because I searched mi in the database which is part of the username in mike123 What would be the problem?

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.
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? Hi I need to do a SELECT query like $query = "SELECT name FROM myusers WHERE myidnum = ".$_SESSION['myid'].""; and put the results into an array like $myusers = array("David","John","Lucy","Sarah"); But I cannot figure out how to do this Can anyone help? Thanks hi i have this function for select / function select($table, $rows = '*', $where = null, $group = null, $order = null, $limit = null) this is what i do to display the records. $db->select('loan'); $records = $db->getResult(); foreach($records as $row) { $user = $row['id']; //$name = $row['firstname']; //print_r($row); echo $user; ?> the codes is running.but when i want to use WHERE id = $_POST['id']; this is what im doing. $db->select('member')->where(array('id' => $_POST['client'])); an error as occured where in function where is not existing. please help how to use the proper way of using select * $table where id=$id; in array. thanks 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.

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 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

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, Im trying to write a select query that has two conditions.
