PHP - While Loop Leaves Out One Column Entry
Code: [Select]
$db_connect = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME); $sql_get = "SELECT DISTINCT category FROM con"; $sql_run = mysqli_query($db_connect, $sql_get) or mysqli_error($db_connect); $sql_assoc = mysqli_fetch_assoc($sql_run); while($sql_assoc = mysqli_fetch_assoc($sql_run)){ echo $sql_assoc['category']; } From the column "category" I get printed 5 distinct entries, though the SQL statement itself does print out 6 distinct entries in MySQL, which is the right one. Just wondering why does the while loop leave out one entry? Also in the array is the "category" identifier necessary since it is identified in the SQL statement already? How would it look differently? Similar TutorialsHello there. I have a small form the inputs a new message into the column 'status'. But when I insert the new text, it deletes whatever is already in the column and leaves it blank. It will never add the new text to the column. Here is the form: $status_sql=mysql_query("SELECT status FROM global"); $status_data=mysql_fetch_assoc($status_sql); echo '<br /><br />Current Status Message: '.$status_data['status'].'<br />'; echo '<form name="status" method="post" action="?page=panel&action=sdo"><input type="text" class="console" name="status"> <input type="submit" class="cbutton" value="Enter"></form>'; $status = mysql_real_escape_string($_POST['status']); $update=mysql_query("UPDATE global SET status='$status' WHERE id='1'") or die('Query: ' . $update . '<br />Failed with: ' . mysql_error()); echo '<br />Status changed to: '.$status.''; If you need more info, just let me know. Thank you a million! Basically I want to group a bunch of rows together to get the oldest entry which is a unix time stamp, so I can compare that to another variable.
I would like to know if this query is correct to get the oldest entry in "table.replyUnixTime"?
SELECT table.*, MAX(table.replyUnixTime) AS lastReply FROM table GROUP BY table.replyId ORDER BY lastReply DESCThanks So I have a list of events happening on certain dates Date event event event Date event event Date event Date event event i.e the number of events per date change. The whole list is stored in an array called $matches. Depending on the formatting of the event or date tells the computer (or me) whether it is an event or a date. So the locations of the dates within $matches[] are stored in the array $dayKeys, and the position of the events within $matches[] is stored in the array $tournKeys. I am trying to print the list back out in the correct order. Code: [Select] foreach($dayKeys as $a => $b) { $c = $a; foreach($tournKeys as $c => $d) { if (($tournKeys[$c] > $dayKeys[$a]) && ($tournKeys[$c] < $dayKeys[$a+1])) //if both are true print the events until it is required to print the next date as oppposed to an event. { ......print the data from matches..... } } } I have tried to simplify the above loops as much as possible for this thread. My point is though, that when I am at the end of $dayKeys, $dayKeys[$a+1] generates an error, because there are no more $dayKeys. So my question is how should I rephrase that if condition so that I dont have to look to see whether The next thing to print is a date or an event by looking at the next $dayKeys value? I have forum options in a loop (ie value = Entry$i) I need to call GET_POST('Entry$i') and loop though the INSERT query $i times. If I put GET_POST in a loop, however, it does not work. It does not give an INSERT failed error so I assume it is not reading it. I have also tried putting if GET_POST('Entry1') outside the loop, but it does not like it. I dont know how many options are needed so I need it to generate the correct number. Then you can select $i options from duplicated option lists. (Ie) participant 1, 2 and 3 from a list of possibles. I have also use GET_POST, I use a function. Other sumbits (I not use what they are called, please set me know), work fine on this page. Code: [Select] echo "Entry $Number: <select name = \"Entry$j\">"; for ($i = 1; $i<$EntNum+1; $i++) { etc etc then for ($i = 0; $i<$NumberOfEntrys; $i++) { if (isset($_POST['AddEntry']) && isset($_POST["Entry$i"])) //rest of this bit not executed -just insert Ideas?

I have used this code before for 2 columns but and now wanting to use for three columns.
There are 5 records from a join query. The first two columns display the results, 2 results in the left column and 3 results in the center column. The right column displayw empyt text used in displaying the results, there is no data to populate and it seems to mimic the the number from the center, 3.

Mike Alright, wasn't quite sure how to summarize this in the title, but I want to: Check if a user status is "active" or not based on the UserName input. I have a table witch holds: Code: [Select] VarChar Username Var CharPassWord int Active Ted TedsPW 1 something like the above(assuming it formatted correctly.

Thanks for any help. I am using php to upload a file to my server, and at the same time inserting the files name and url into my mysql database.
$sql = "UPDATE uploads SET name = '$name', url='$target_path'"; $statement = $dbh->prepare($sql); $statement->execute();This is working, however, when I upload a new file, rather than making a new entry in my database, it just overwrites the first one. I'm quite new at mysql so was wondering how I would make it add new entrys instead of overwriting the current one? Hey there, Thanks for reading this thread. I've come across a problem where I cannot get the text to echo properly upon retrieval from the database, here is a example; Now this is where I echo the text: function ListPosts($PageLimit) { $Posts = mysql_query("SELECT * FROM posts"); while($Post = mysql_fetch_array($Posts)) { echo("<div class=\"art-Post\"> <div class=\"art-Post-tl\"></div> <div class=\"art-Post-tr\"></div> <div class=\"art-Post-bl\"></div> <div class=\"art-Post-br\"></div> <div class=\"art-Post-tc\"></div> <div class=\"art-Post-bc\"></div> <div class=\"art-Post-cl\"></div> <div class=\"art-Post-cr\"></div> <div class=\"art-Post-cc\"></div> <div class=\"art-Post-body\"> <div class=\"art-Post-inner\"> <h2 class=\"art-PostHeader\">{$Post['post_subject']}</h2> <div class=\"art-PostContent\"> <p>{$Post['post_contents']}</p> </div> <div class=\"cleared\"></div> </div> <div class=\"cleared\"></div> </div> </div>"); } } Hi
I am very new to PHP & Mysql.
I am trying to insert values into two tables at the same time. One table will insert a single row and the other table will insert multiple records based on user insertion.
Everything is working well, but in my second table, 1st Table ID simply insert one time and rest of the values are inserting from 2nd table itself.
Now I want to insert the first table's ID Field value (auto-incrementing) to a specific column in the second table (only all last inserted rows).
Ripon.
Below is my Code:
<?php $con = mysql_connect("localhost","root","aaa"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("ccc", $con); $PI_No = $_POST['PI_No']; $PO_No = $_POST['PO_No']; $qry = "INSERT INTO wm_order_entry ( Order_No, PI_No, PO_No) VALUES( NULL, '$PI_No', '$PO_No')"; $result = @mysql_query($qry); $val1=$_POST['Size']; $val2=$_POST['Style']; $val3=$_POST['Colour']; $val4=$_POST['Season_Code']; $val5=$_POST['Dept']; $val6=$_POST['Sub_Item']; $val7=$_POST['Item_Desc']; $val8=$_POST['UPC']; $val9=$_POST['Qty']; $N = count($val1); for($i=0; $i < $N; $i++) { $profile_query = "INSERT INTO order_entry(Size, Style, Colour, Season_Code, Dept, Sub_Item, Item_Desc, UPC, Qty, Order_No ) VALUES( '$val1[$i]','$val2[$i]','$val3[$i]','$val4[$i]','$val5[$i]','$val6[$i]','$val7[$i]','$val8[$i]','$val9[$i]',LAST_INSERT_ID())"; $t_query=mysql_query($profile_query); } header("location: WMView.php"); mysql_close($con); ?>Output is attached. My Php Buddies, I have mysql tbl columns these:

So, the User's (eg. your's) homepage inside his account should display labels like these where labels match the column names but the underscores are removed and each words' first chars CAPITALISED:

So the issue I'm having is consecutive loops on semi-large arrays, over and over. Consider this array:

But to ilustrate the point, this is how the main array looks like. This array usually contains anywhere between 10-50 rows, each row containing at least 10 dates, with 10 key/values each. And after setting up all the data, it needs to be processed. Currently this is how a friend of mine did it.. $placeDataHere = array(); foreach($firstArray as $key => $dates) { foreach($dates as $date => $values) { foreach($values as $key => $value) { $placeDataHere['DV_' . $date]['SM_' . $key] = 'KS_' . $value; //Followed by another ~50-70 lines of processing the 3 loop's data.. ... ... .... .... .... .... .... .... } } }Obviously this isn't good practise, but we can't seem to figure out a better way of doing it, since both the data and the loops are horribly nested. This loop and setup of $firstArray is run anywhere between 10-20 times/request, due to amount of users we wish to process. So, the result is that this code can take up to over 2-3 minutes to complete, which isn't really optimal performance. In short my question is, are there any better methods of handling this with the data setup we currently have? Below is my output on the browser: Student: Kevin Smith (u0867587) Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade Year: 3 Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B Session: AAB Session Mark: 72 Session Weight Contribution 20% Session: AAE Session Mark: 67 Session Weight Contribution 40% Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B Session: AAD Session Mark: 61 Session Weight Contribution 50% Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this. Below is the code: Code: [Select] $sessionMark = 0; $sessionWeight = 0; $courseMark = 0; $output = ""; $studentId = false; $courseId = false; $moduleId = false; while ($row = mysql_fetch_array($result)) { $sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']); $sessionWeight += ($row['SessionWeight']); $courseMark = ($sessionMark / $sessionWeight * 100); if($studentId != $row['StudentUsername']) { //Student has changed $studentId = $row['StudentUsername']; $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n"; } if($courseId != $row['CourseId']) { //Course has changed $courseId = $row['CourseId']; $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong> <br><strong>Year:</strong> {$row['Year']}</p>\n"; } if($moduleId != $row['ModuleId']) { //Module has changed if(isset($sessionsAry)) //Don't run function for first record { //Get output for last module and sessions $output .= outputModule($moduleId, $moduleName, $sessionsAry); } //Reset sessions data array and Set values for new module $sessionsAry = array(); $moduleId = $row['ModuleId']; $moduleName = $row['ModuleName']; } //Add session data to array for current module $sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']); } //Get output for last module $output .= outputModule($moduleId, $moduleName, $sessionsAry); //Display the output echo $output; I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72? Hey guys, Got another question im hoping someone can help me with. I have a foreach loop (for use in a mysql query): foreach ($interests as $interest) { $query .= "($id, $interest), "; } problem is i do not want the comma(,) in the last loop. Is there some kinda of function i can use so it does not insert it on last loop? Or should i just use a for loop with a nested if loop? something like ; for($i=0; $i < count($interests); $i++){ $query .= "($id, '$interests[$i]')"; if($i + 1 < count($interests)) { $query .= ", "; } } Cheers guys I am working to echo the results in a while or for loop... Both of my sample codes work, but the results are wrong! The while loop ONLY echos a result IF the first record in the postings table matches the id passed (does not display a result unless the first record has a match) The if loop displays ALL listings with the same name (counts them all) so there are no unique listings! <?php $posts_by_city_sql = "SELECT * FROM postings WHERE id='$_GET[id]'"; $posts_by_city_results = (mysqli_query($cxn, $posts_by_city_sql)) or die("Was not able to grab the Postings!"); /* While Loop */ while($posts_by_city_row = mysqli_fetch_array($posts_by_city_results)) { echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>"; } /* For Loop */ $posts_by_city_row = mysqli_fetch_array($posts_by_city_results); for ($i=0; $i<sizeof($posts_by_city_row); $i++) { echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>"; } ?> Results with for loop (there are 7 total unique book names, but it's just counting the first match on id 7 times like below): AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners Hello there, I have some code here which sends a number of variables from flash to SQL...
