PHP - Counting For Specific Fields That Aren't Null
Hi
I have a table (applicant) that has a number of fields but included a applicantid party1 party2 party3 party4 party5 Any number of these party entries could have data in them but I need to know, for any specific applicantid, the count of how many non null entries there are. I can't find a way to do it. Does anyone have any ideas. Many thanks Similar TutorialsI wish to have a page that will display a form if there aren't already enough registrations in the database. The following it an outline of how it will be: <?php require_once "../scripts/connect_to_mysql.php"; //this works fine // Count how many records in the database (1) $sqlCommand = "SELECT * FROM teams"; (2) $sqlCommand = "SELECT COUNT (*) FROM teams"; (3) $sqlCommand = "SELECT COUNT (id) FROM teams"; $query = mysqli_query($myConnection, $sqlCommand) or die (mysqli_error()); (1) $numRegistrations = mysql_num_rows($query); //Count how many rows are returned from the query above (2) $numRegistrations = $query (3) $numRegistrations = mysql_num_rows($query); mysqli_free_result($query); ?> (Some HTML code, like DOCTYPE, head, start of body tags) <?php if($numRegistrations > 35){ echo "Sorry, registrations for this event is at it's maximum."; }else{ ?> <form blah blah blah> </form> <?php } ?> (end of body and html tag) You'll see above there is (1), (2), (3). These are the main 3 that I've been trying, and they match up the $sqlCommand to the $numRegistrations. What would be the problem with this code? I use wamp server to test, have been using it for ages. Chrome browser to test in. If I remove the database query, the rest of the page will load. With the query in there, only the HTML code up until the database query is parsed, so therefore nothing is display on the page. Please help. Thanks Denno Sorry if this is very basic. We have our church membership lists in a MySQL database with the following fields: Surname Person1 Person1_Membership Person2 Person2_Membership ... The membership fields will either be empty or contain "Resident" or "Non-Resident". The reason for two columns is that some couples may only have one partner as a member. I am trying (without success) to find a way of getting a total (to display on a web page) of how many "Resident" and how many "Non-Resident" members we have. In other words, I'm trying to get a sum of the total number of times "Resident" and and total number of times "Non-Resident" appears in the two columns combined. (hope that makes sense!) I would appreciate any pointers from anyone who has managed to do this, or something similar, already. Many thanks for the help I have got another of those problems that should be easy to solve but I cannot get my head round it! I have a form to enter data into a table and one of the fields can be left blank. However, I'd data is entered in the field it can be a Zero. This is leaving me a problem as I cannot find a way to get the script to insert NULL if the field is blank but actually put the Zero in if that is what is entered. I have tried several permutations of nested if's using empty or isset, but whatever I try, the same result is inserted in both scenarios. The arguments I need to pass are...... If field is empty INSERT null If field is 0 INSERT 0 If field is not empty and not 0 INSERT field Thanks in advance for any suggestions. Steve Below is the code I'm using, and I would like for when the information is sent to email that it omits empty fields including the field name. I'm not real sure on how to do this. Any help would be great!!!! Thanks!!!!! Code: [Select] ]<?php $SendFrom = "Form Feedback <feedback@yourdomain.com>"; $SendTo = "feedback@yourdomain.com"; $SubjectLine = "Feedback Submission"; $ThanksURL = "thanks.html"; //confirmation page foreach ($_POST as $Field=>$Value) $MsgBody .= "$Field: $Value\n"; $MsgBody .= "\n" . @gethostbyaddr($_SERVER["REMOTE_ADDR"]) . "\n" . $_SERVER["HTTP_USER_AGENT"]; $MsgBody = htmlspecialchars($MsgBody, ENT_NOQUOTES); //make safe mail($SendTo, $SubjectLine, $MsgBody, "From: $SendFrom"); header("Location: $http://www.yourdomain.org"); ?> [/code A select query I've written joins three tables. The query works fine, pulling up a users table, a table for specials advertising that are entered by members, a and a third table the identivies members who have joined a customer application.
A page displays listing all the entries who have joined the customer application, their names, address, etc display but if they have not set up their special advertising, then the fields for that table display NULL.
I have tried an If and an ifelse to not display text (you can see in the code the HTML Hours of Operation: and Specials:). Thee field I am using to differentiate is "m_primeID", it is an intiger field. The if statement I've written is follows.
if( $row["$m_primeID"] == 'NULL' )
{
$company .= "";
}
elseif( $row["$m_primeID"] <> 'NULL' )
{
$company .= "<b>Hours of Operation:</b><br>" . ($row["m_coupon_title"]) . "<br /><br />\n";
$company .= "<b>Special:</b><br>" .($row["m_coupon_desc"]) . "<br /><br />\n";
}
Here is a screen shot of part of the joined tables.
This screen shot show the Null on the joined tables that don't have customer advertising set up.
Any Ideas

0 downloadsNovice in way over head here! Created a mySQL db. populated with a bunch of data in one table. have a simple file based login/authentication system that i've setup. now im looking to establish some sort of process where specific users login and see specific fields. something like if userX see fields 1,2,4. if userY see fields 1,2,3. SQL statements?? im completely lost on the logic how that might be best created. hoping someone might point me in right direction...been spinning wheels. I am trying to update the database with isset to set the value of the variable to either null or the value entered by the user. Currently, if no value has been entered null is being set as a string causing the date field to populate with zeros. How do I code it so that it populates or sets the value as null and not as string null?
Here's my code: (yes I know sql injections it's still in development )
<?php I use the Wholesale Suite Premium Prices plugin with WooCommerce. I have 6 specific wholesale roles out of 15 that I wish to hide two specific shipping methods from being selected for the 6 exceptions. I'm just trying this on my staging server at this time using a code snippet example that I found and modified for my specific conditions. Would the following work for this purpose?
/* Hide specific shipping methods for specific wholesale roles */
add_filter( 'woocommerce_package_rates', function( $shipping_rates ) {
// User role and shipping method ID to hide for the user role
$role_shipping_method_arr = array(
'ws_silvia_silver' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_silver_pst_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_silver_tax_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_silver' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_silver_pst_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_silver_tax_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_gold' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_gold_pst_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_gold_tax_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
'ws_silvia_gold' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
'ws_silvia_gold_pst_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),

$curr_user = wp_get_current_user();
$curr_user_data = get_userdata($current_user->ID);

Any insights as to how to accomplish this would be greatly appreciated. Lyse Here are the two if statements: if (!($start <= 0)){ $prev_button = "<a href='forum.php?category_id=$category_id&start=$prev'>Prev</a>"; } if (!($start >= $record_num - $per_page)){ $next_button = "<a href='forum.php?category_id=$category_id&start=$next'>Next</a>"; } But they are not properly working. This is part of a pagination script for the next and previous buttons. Hey guys, Really dumb question, but I want to check if a bunch of variables are all not empty. Then, if they aren't, I want to execute a mySQL query. Right now I have this which I know is wrong because it doesn't work the right way: Code: [Select] if($album != null || $artist != null || $year != null || $genre != null) { // stuff here... } Obviously I want all of those variables to be checked if they are empty or not. I did a quick Google and found that checking if the variables are null wouldn't be the correct way of solving this situation because an "empty string" is still not null? Anyway, any help would be appreciated. I'm pretty sure it's really simple :p. Hi all, Something i forget to ask all the time, but now i don't. While reading again about image sprites, it tells that it's nice because it decreases the amount of http requests. Now I thought what about all those requires and includes of php aren't they doing the same thing? Not to mention OOP which would not exist without the 2(4). Does anyone know if this indeed increases the amount of http requests. And if so, if there is a certain good practise to lower the amount, by just combining functions in 1 file. I would love to hear from some guru's Hey guys,
Thank you in advance... here is my situation, I have a form with three (3) fields in it, the 'student name' is unlimited textfield with an "add more" button to it and I have two select fields ('number of shirts' and 'trophies') that depend on the number of entries for 'student name'...
I want to create the select fields based on this math, for as many 'student name' entries:
1- i want to have the select form for 'number of shirts' to be 0 up to that number... so if there are 6 'student name' entries, the select options will be 0,1,3,4,5,6,7
2- I want to have the select form for 'trophies' to be 5 'student name' entries to 1 'trophies', for example if there are 6 'student name' entries, the select options will be 0,1... if there are 13 entries, options will be 0,1,2... So if there are less than 5 'student name' entries, the select field will not show (hidden)
of course if there are no 'student name' entries, these two fields won't show up (hidden)
let me know if that make sense and ANY help or directions will be GREATLY APPRECIATED.
Thanks guys!
Hi im trying to make it so the time says how many hows left, not how many hours past. i have the right idea but it shows a negative number under "$time" $hours = number_format(($diffrence / 60 / 60)); $time = number_format(($hours - 24)); I have a table in my database named order, and i want to count the quantity sold. i have the basic query already setup like: Code: [Select] $sql = "SELECT SQL_CALC_FOUND_ROWS deal.id, deal.title, deal.min_qty, deal.start_date, deal.end_date, deal.status, deal.secondary, count(o.id) as orders_cnt FROM deals as deal LEFT JOIN orders as o on o.d_id = deal.id WHERE start_date >= '".$beg."' AND start_date <= '".$end."' GROUP BY o.d_id, deal.id ORDER BY start_date LIMIT ".AwsPager::getCurrentIndex().", ".AwsPager::getLimit(); Which would theoretically work, but in the orders table, there is a column named quantity, and its those numbers that i need to add together and store in the array as orders_cnt.. any clue how i can do that?

hey guys iam starting to learn during this crysis php :-). I got stucked with this pdo style..... i like to count logins, i tryed and figured out i can use the id... but my question is how can replace this "where user_id=2" to get the specific ID for the current user login in? the count function i i know how to make the... first i want to know how to write the syntax of this pdo...... thank you :-) I have an array. When I print it it looks like this: Quote Array ( [1] => Array ( [Cushion] => Cushion 1 [Fabric] => f-111111 [FabricPrice] => 0 [Fill] => Fiber [Button] => none [ContWelt] => none [ContWeltFabric] => none [Zipper] => N [Quantity] => 2 [WeltSize] => [SKU] => c-111111 [Edge] => Knife [Cap] => N [Straps] => N [Hinged] => N [Type] => Boxed Button [Price] => 54.25 [Total] => 108.5 ) [2] => Array ( [Cushion] => Cushion 1 [Fabric] => f-111111 [FabricPrice] => 0 [Fill] => Fiber [Button] => none [ContWelt] => none [ContWeltFabric] => none [Zipper] => N [Quantity] => 4 [WeltSize] => [SKU] => c-111111 [Edge] => Knife [Cap] => N [Straps] => N [Hinged] => N [Type] => Boxed Button [Price] => 54.25 [Total] => 217 ) ) Now when I use count() I get a result of 01 when I should get 02 when I use count( ,1) I get a result of 381. I am Using this wrong? the array is stored in $_SESSION['cushArray'] Hiya peeps, I have a mysql database with a record of all the images a customer uploads on my site, these images are displayed on there account. I can get this to work but the problem I'm facing is I need a minimum of 5 images displayed so if they only upload 2 images for instance I need to detect that and add my "No Image Uploaded" image. But if they have uploaded 5 or more I need to just let them be displayed without adding the "No Image Uploaded" picture. Does anyone have any ideas as I'm very stuck! Many thanks James. I have a page that displays a list of retail locations (est. 100-150 locations). I have my layout setup to fit 3 columns side by side. Ex: <div class="col"></div> <div class="col"></div> <div class="col"></div> .. with the "col" class having a specific width and float: left. Basically, I want to print out the locations in the column and when a column reaches a certain number of locations, it closes that div and starts a new one and continues printing the rest of the locations. How would I go about making sure that once a column has reached a certain number of locations, it closes the div and starts the new one? I know how to count the files: <?php $dir = $_SERVER[DOCUMENT_ROOT]."/api/sigs/cache/".$i[id]."/"; $files = scandir($dir); $result = count($files); printf("$result Signatures Generated"); ?> But i'm trying to make it so it only counts the files that were modified recently (That Day). Hello, I'm creating a program that analyzes information that is exported by another program. That program exports it in this way: Value1 Value2 Value3 Value4 Value1 Value2... In order to insert them in the database, I first have to know how many lines are inserted. They get send through HTML post. I already tried: $lines = explode("\n", $string); $number_lines = count($lines); But this always results in 1. How do I fix this? Regards, Chris |
