PHP - Print The Results Of A Query
Hi, say I have a query like so:
foreach($_REQUEST['r'] as $position => $row) { $row = implode("', '",$row); $result = mysql_query("Insert into player_stats (position,shirt_number,player_id,goals,cards,substituted,used_sub,injury,season,report_id) values('$position','$row','$currentSeason','$report_id')"); } How do I print the results of that query to my Browser for each time? Thanks Similar TutorialsHello 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!

What I'm trying to achieve is to get a set of data from a database and then cycle through the array and add the contents of each row to a variable. I'm trying to use $i to cycle through the array but at the moment it's just printing the first character of each set. Any help would be great. $fav_products_sql = "select fav_products.product_id, fav_products.product_order, product_list.product_name from fav_products, product_list where fav_products.product_id = product_list.id"; $fav_products_rs = mysql_query($fav_products_sql, $conn); $fav_products = mysql_fetch_array ($fav_products_rs); while ($i < 11) { $_SESSION['fav_products'] = "<li>" . $fav_products['product_order']['$i'] . ": " . $fav_products['product_name']['$i'] . "</li>"; $i++; } I need to echo the "reward.id" Code: [Select] $sql = "select reward.id, reward.location, reward.industry, reward.title, reward.stamp, industry.id, industry.label, industry.location FROM reward LEFT JOIN industry ON industry.id = reward.industry where (industry.label = '".$_GET['ind']."' and industry.location = '".$_GET['loc']."')"; $result = mysql_query($sql) or die(mysql_error()); while($info = mysql_fetch_assoc($result)){ echo $info['HOW TO I PRINT reward.id']; }free($result ); Any thoughts? Hello, Having a bit of a tough time understanding what is going on in my brain! I'm basically pulling some data from an API using CuRL, which is working fine. The structure of the data is: [data][tickets] - tickets being an array of support tickets in the system, which then contains ticketNumber, title, content. I want to display these values in a list, I have this code currently:
if ($err) {
echo "cURL Error #:" . $err;
} else {
$return = json_decode($response, true);
foreach($return as $key) {
echo $key["tickets"][1]['ticketNumber']." - ";
echo $key["tickets"][1]['title']." - ";
echo $key["tickets"][1]['content'];
}
}
Which obviously returns the ticketNumber, title & content of the first support ticket in the array, but I want to loop through and display that information for each ticket! Can anyone advise as to where I am going wrong? I think I need to utilise the ["tickets"][x] but not sure how!
Thanks in advance! Steve I have two arrays, X and Y, which contain names. The arrays are of the same size. The arrays are related to each other such that for each pair X[n] , Y[n] X is friends with Y. For example: X[0,1,2] = [Link, Cloud, Cloud, Mario, Mario, Luigi] Y[0,1,2] = [Zelda, Barrett, Tifa, Luigi, Bowser, Mario] Link is friends with Zelda Cloud is friends with Barrett and Tifa Mario is friends with Luigi and Bowser Luigi is friends with Mario I want to loop through these arrays and, for each unique name, find all of that person's friends. I then want to print the results to a text file, like so: Link, Zelda Cloud, Barrett, Tifa Mario, Luigi Luigi, Mario I know how to do this theoretically, but I just need help with the PHP syntax. Thanks very much. What would be the correct way to close a mysql query?

I tested the switch and nested switches by setting up the structure, and using basic text for the cases. For example, instead of one of the nested switch cases needing to = $_GET['id'], I just entered two cases, each equaling 1 and 2, then the default case. Once I begin to enter my SQL coding to connect to the databases, only certain information prints. For example; on my switch that is $_GET['page'], I have a case for 'news'. Inside this case, I have a nested switch called $_GET['id'], which will display information if the page=nes&id=whatever. That works, but when I go do the page=news, nothing displays. My coding is omitting displaying the default information if there is no $_GET['id']. Attached, I am going to have my .php file. The reason for not posting it here is because my coding is rather messy. Please help! 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?

Any help is highly appreciated! Hello all, I am new here so thank you in advance for all of your help. I am writing a pretty simple search script to display data from a table however have run into a snag. Things seem to get complicated all by themselves. I have a drop down to select the predetermined search criteria, because the data has either a 'Y'es or 'N'o. For example there are 50 or so products/brands with ingredients/categories in them. i.e. Brand X contains Sugar=Y, Salt=Y, Vinegar=N Brand Y contains Sugar=N, Salt=N, Vinegar=N Brand Z contains Sugar=Y, Salt=Y, Vinegar=Y Brand A contains Sugar=N, Salt=N, Vinegar=Y I want to display the brands that contain only the selected ingredients. I have added check boxes for the user to select. This runs ok however the return is more of a broader result and requires too much interpretation from the user. i.e. If I want to know which brands contain only salt and vinegar ??BRAND??= Sugar=N, Salt=Y, Vinegar=Y or ??BRAND??= Salt=Y, Vinegar=Y The return comes back: Brand X contains Sugar=Y, Salt=Y, Vinegar=N Brand Z contains Sugar=Y, Salt=Y, Vinegar=Y Brand A contains Sugar=N, Salt=N, Vinegar=Y Ideally the return Should only be: Brand Z contains Sugar=Y, Salt=Y, Vinegar=Y I believe the else if statement would work, I just have no knowledge of where to put it or how it would work. Any suggestions would be greatly appreciated.

WHERE thread_id='{$ThreadID}'", $db), 0, 'forum_id'); $PostText = mysql_escape_string($_POST['replytext']); $IP = $_SERVER['REMOTE_ADDR']; $PostQuery = "INSERT INTO ".FORUM_POSTS." (`user_id`, `thread_id`, `post_text`, `forum_id`, `ip_address`, `timestamp`) VALUES ('{$memid}', '{$ThreadID}', '{$PostText}', '{$ForumID}', '{$IP}' , CURRENT_TIMESTAMP)"; $PostRes = mysql_query($PostQuery, $db); For some reason whenever this query goes through, it also adds a blank result using all the same information but without any $PostTest so essentially it does query: Code: [Select] INSERT INTO ".FORUM_POSTS." (`user_id`, `thread_id`, `post_text`, `forum_id`, `ip_address`, `timestamp`) VALUES ('{$memid}', '{$ThreadID}', '', '{$ForumID}', '{$IP}' , CURRENT_TIMESTAMP) This is the only query that does this part of the code and I can't see why it is adding 2 queries. FORUM_POSTS = constant containing table name. Hi all, I'm new to php and I was trying to send the results of one query to another query. I need the results of both queries. Here are the queries $cui1 = mysql_query("SELECT DISTINCT CUI FROM MRSTY WHERE STY='ABC' "); $cui2 = mysql_query("SELECT DISTINCT CUI FROM MRSTY WHERE STY='XYZ' "); I want to know if this is possible $cuis = mysql_query("SELECT CUI1,CUI2,REL FROM MRREL WHERE CUI1 IN $cui1 OR CUI1 IN $cui2 "); Thanks. this is my query code Code: [Select] <?php $wsi_query = "(SELECT * FROM (SELECT a.no_Yards AS 'yards', a.Day_Swam AS 'date', a.Season AS 'season', (SELECT sum(no_yards) FROM swimming WHERE Season = '$ws') AS 'totalyards', (SELECT AVG(no_Yards) FROM swimming WHERE Season = '$ws') AS 'avg', (SELECT count(*) FROM swimming WHERE Season ='$ws') AS 'timelaps', (SELECT 1 + count(*) FROM swimming b WHERE b.no_Yards > a.no_Yards AND Season = '$ws') AS hrank, (SELECT 1 + count(*) FROM swimming b WHERE b.no_Yards < a.no_Yards AND Season = '$ws') AS lrank FROM swimming AS a) AS x WHERE Season = '$ws' )"; $wsi_result = mysql_query($wsi_query) or die("Query failed ($wsi_query) - " . mysql_error()); $wsi_row = mysql_fetch_assoc($wsi_result); ?> what it should do is output both the min and the max values like this Code: [Select] <?php while ($mm_wsi_row = mysql_fetch_assoc($wsi_result)){ if ($mm_wsi_row['hrank'] == 1){ if ($mm_wsi_row['date'] == "0000-00-00"){$dayswam = "";}else{$dayswam = $mm_wsi_row['date'];} echo "<tr>"; echo "<td style='background-color:#F90'>Max Length:</td>"; echo "<td>" . number_format($mm_wsi_row['yards']) . "</td>"; echo "<td>" . $dayswam . "</td>"; echo "</tr>"; } if($mm_wsi_row['lrank'] == 1){ if ($mm_wsi_row['date'] == "0000-00-00"){$dayswam = "";}else{$dayswam = $mm_wsi_row['date'];} echo"<tr>"; echo "<td style='background-color:#F90'>Min Length:</td>"; echo "<td style='background-color:#FF9'>". number_format($mm_wsi_row['yards']) . "</td>"; echo "<td style='background-color:#FF9'>" . $dayswam . "</td>"; echo "</tr>"; } ?> the problem is that it doesn't work right all the time for some it just shows the min while others it just shows max I've tested the query in MySQL workbench so i know that that is working right but idk why it works right for some and doesn't work for others Code: [Select] $PlayerQuery = "SELECT FirstName, SurName FROM players p, rounds m, entrants e, games t WHERE p.PlayerID = e.PlayerID AND m.GameID = '$ID' AND e.EntrantID = m.Player"; $PlayerResult = mysql_query($PlayerQuery); $PlayerRow = mysql_num_rows($PlayerResult); Can someone suggest why this returns game*the number of results. For each new game it returns an extra duplicate result. For example for 2 games: j Smith j Smith t John t John etc There are no duplicate entry's! and results should be unique. Not in a loop (positive) |
