PHP - Count Rows In Phpmyadmin
Hi. I having trouble with counting rows in phpmyadmin.
It works fine this way: Code: [Select] $result_rows = mysql_query("SELECT * FROM events"); But when i modify the code to this it doesnt work at all. Code: [Select] $result_rows = mysql_query("SELECT * FROM events WHERE category = 'adults' ORDER BY 'date'"); Any idea what is wrong? Similar TutorialsHi guys, I want to count the number of rows in a table and want to display them. However that field stays empty. Everythign else works. What do I do wrong?

Code: [Select] $num=mysql_num_rows($sql); - Pranshu Agrawal pranshu.a.11@gmail.com Hi I'm not at all good at PHP and haven't really played with it for some years, so bare with me if code examples are old I'm looking for a simple solution to count rows (MySQL), without using multiple queries. The below code is quite simple, counting rows where 'Department' is 'Sales': $sql ="SELECT * FROM DB WHERE Department ='Sales'"; $result=mysqli_query($con,$sql); $rowcount=mysqli_num_rows($result); But what If I need to count the rows for the different departments?: $sql ="SELECT * FROM DB WHERE Department ='Sales'"; $result=mysqli_query($con,$sql); $rowcount=mysqli_num_rows($result); $sql ="SELECT * FROM DB WHERE Department ='Support'"; $result=mysqli_query($con,$sql); $rowcount=mysqli_num_rows($result); $sql ="SELECT * FROM DB WHERE Department ='Online'"; $result=mysqli_query($con,$sql); $rowcount=mysqli_num_rows($result); There must be a better / simpler way to this with a single query? Hope for someone to show me the light
PS. Once this is resolved, I'll probably need further help, to accomplish my final result. I have a mysql table that holds data for cars - each car has it's own ID, name, and year. Some cars are repeated. Example: (ID - year - car name) 0001 - 2009 - Honda Civic 0002 - 2008 - Toyota Prius 0003 - 2009 - Honda Civic 0004 - 2008 - Toyota Prius 0005 - 2008 - Toyota Prius 0006 - 2007 - Honda Civic How would I count how many of the same type of cars I have in that table and then display the quantity next to the car name? Like for the above example it would be: 2009 Honda Civic: 2 2007 Honda Civic: 1 2008 Toyota Prius: 3 Thanks in advance for any help :D It's late and I'm not thinking straight. I'm posting this question. Hopefully I get a reply in the morning. I have two tables. TABLE 1 - PRODUCTS TABLE 2 - LIKES I am a User who has posted these products. I want to find out ALL the Likes I have received for all my products. Here is my code. $find_products = $db->prepare("SELECT product_id FROM products WHERE user_id = :user_id"); $find_products->bindParam(':user_id', $my_user_id); $find_products->execute(); $result_products = $find_products->fetchAll(PDO::FETCH_ASSOC); if(count($result_products) > 0) { foreach($result_products as $row) { $product_id = $row['product_id']; $find_likes = $db->prepare("SELECT like_id FROM product_likes WHERE product_id = :product_id"); $find_likes->bindParam(':product_id', $product_id); $find_likes->execute(); $result_likes = $find_likes->fetchAll(PDO::FETCH_ASSOC); if(count($result_likes) > 0) { $get_likes = 0; foreach($result_likes as $row) { $get_likes++; } } } } The issue with the above code is that It only shows the Likes if I echo inside the foreach loop. And it'll show combined Likes from each of my products. But I want to actually combine ALL the Likes from ALL the products and be able show them as a single number, outside of the foreach loop. How do I do that?

My question is what is the best way to do a row count for the id column with this query or do I need to do a second db query to accomplish this? The purpose of this is to echo out the number of comments for that post, before displaying them. Any help is appreciated. Thanks in advance, kaiman <?php // get url variables $post_id = mysql_real_escape_string($_GET['id']); include ("../../scripts/includes/nl2p.inc.php"); // connects to server and selects database include ("../../scripts/includes/dbconnect.inc.php"); // table name $tbl_name3="blog_comments"; // select info from comments database $result3 = mysql_query ("SELECT count(*) FROM $table_name3 WHERE id='$post_id' ORDER BY id DESC LIMIT 1") or trigger_error("A mysql error has occurred!"); if (mysql_num_rows($result3) > 0 ) { while($row = mysql_fetch_array($result3)) { extract($row); // display number of comments // display date $row_date = strtotime($row['date']); putenv("TZ=America/Denver"); echo "<p class=\post\">On ".date('F, jS, Y', $row_date)."

I want to echo out the number of rows where 'friend_system_accepter' = $myusername Thanks Folks, Having trouble here. Forgot how you use the COUNT. Not interested in the num_rows due to it being slow compared to COUNT. I have users table like this: id|username|sponsor_username 0|barand|requinix 1|phpsane|alison 2|mickey_mouse|requinix Now, I want to check if a sponsor username exists or not. Such as does the entry "requinix" exists or not in one of the rows in the "sponsor_username" column. In our example it does twice and so the variable $sponsor_username_count should hold the value "2". Else hold "0". I get error: Fatal error: Uncaught mysqli_sql_exception: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '?' at line 1
My code:
$stmt_1 = mysqli_prepare($conn,"SELECT COUNT(sponsor_username) from users = ?"); mysqli_stmt_bind_param($stmt_1,'s',$sponsor_username_count); mysqli_stmt_execute($stmt_1); //Show error if 'users' tbl was not successfully queried". if (!$stmt_1) { echo "ERROR 1: Sorry! Our system is currently experiencing a problem loading this page!"; exit(); } else { mysqli_stmt_bind_result($stmt_1,$sponsor_username_count); mysqli_stmt_fetch($stmt_1); mysqli_stmt_close($stmt_1); //Check if Sponsor Username in Url ($_GET) is already registered or not. If not then show "Invalid Url" or Link message. if ($sponsor_username_count < 1) { echo "<b>Invalid Url or Link!<br> Invalid Sponsor: \"$sponsor_username\"!</b><?php "; exit(); } }
The following works, but I don't want to have to write 50 query statements for 50 states. How can I just write one query (using a variable I presume) and then echo the variable count each time for each state? I'm just trying to list the total number of rows for each state, that exist in the db. <? $result = mysql_query("SELECT * FROM mytable WHERE source = 'alabama'") or die(mysql_error()); $num_rows = mysql_num_rows($result); ?> href="/state/alabama/">alabama</a> (<?php echo("$num_rows");?>) <br> <? $result = mysql_query("SELECT * FROM mytable WHERE source = 'alaska'") or die(mysql_error()); $num_rows = mysql_num_rows($result); ?> href="/state/alaska/">alaska</a> (<?php echo("$num_rows");?>) <br> The above would give output such as: alabama (122) alaska (212) I have a html table displaying data from mysql database. I can count rows properly with mysql_num_rows but is there a way to echo which row number it is. What I want to do is count the rows ordered by cities and echo row number. Thanks for any help.

Question 2: Email Script I have a script that sends an email to a system that sends out multiple sms's. The system works like this, I send an email to an address with an attachment called cellnumbers.txt with a list of all the cellnumbers. I must add a specific subject. When I send the email to my own email address, it comes correctly through. But when it is sent to the address of the server, no sms are received. I attached my script. Please take a look. Your help will be greatly appretiated. Thank you |
