PHP - How To Subtract An Array Of A Column Of Rows From Mysql Db From A Form Number

My Php Buddies,

I have mysql tbl columns these:

id: 
date_&_time: 
account_activation_code: 
account_activation_status: 
id_video_verification_status: 
id_verification_video_file_url: 
username: 
password: 
primary_domain: 
primary_website_email: 
sponsor_username: 
 

Now, I want to display their row data by excluded a few columns.

Want to exclude these columns:

date_&_time

account_activation_code

account_activation_status

id_verification_video_file_url

password

 

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:

Id: 1
Id Video Verification Status: 1
Username: requinix
Primary_domain: requinix.majesty
Primary Website Email: requeen@requinix.majesty
Sponsor Username: phpsane
Recruits Number: 2

 

For your convenience only PART 1 works. Need help on Part 2

My attempted code:

 

	PART 1
	<?php 
	// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
	// Query to get columns from table
$query = $conn->query("SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'members' AND TABLE_NAME = 'users'");
	while($row = $query->fetch_assoc()){
    $result[] = $row;
}
	// Array of all column names
$columnArr = array_column($result, 'COLUMN_NAME');
	foreach ($columnArr as $value) { 
echo "<b>$value</b>: ";?><br><?php 
} 
	?>
	 
	PART 2
	<?php 
	//Display User Account Details 
echo "<h3>User: <a href=\"user.php?user=$user\">$user</a> Details</h3>";?><br> 
<?php 
$excluded_columns = array("date_&_time","account_activation_code","account_activation_status","id_verification_video_file_url","password"); 
foreach ($excluded_columns as $value2) 
{    
    echo "Excluded Column: <b>$value2</b><br>";
}
foreach ($columnArr as $value) 
{ 
    
    if($value != "$value2")
    { 
        $label = str_replace("_"," ","$value"); 
        $label = ucwords("$label"); 
        //echo "<b>$label</b>: "; echo "$_SESSION[$value]";?><br><?php 
        echo "<b>$label</b>: "; echo "${$value}";?><br><?php 
    }
} 
?>
	

PROBLEM: Columns from the excluded list still get displayed.

I have somewhat of a dilemma.

When someone clicks on a Buy Now button and subsequently follows necessary steps to complete process of purchase, when that transaction is completed, in my product table, I want to subtract 1 from whatever value is in the field.

E.g. say product one is being purchased, prior to purchase in product table, there are 5 product one's in stock, when purchase is complete, subtract 1 from 5 (to get 4).

Here is my code

Code: [Select]
<?php

$title = "Like This Product, Buy It NOW!!!";

require ('includes/config.inc.php');

include ('./includes/header.html');

require (MYSQL);

include ('./includes/main.html');

if($id = isset($_GET['prodID']))
{
$query = "SELECT `prodID`, `product`, `prod_descr`, `image`, `price` FROM product WHERE `prodID`='{$_GET['prodID']}'";
$r = mysqli_query($dbc, $query);

$showHeader = true;
echo "<div id='right'>";

while($row = mysqli_fetch_array($r))
{
if($showHeader)
{
            //Display category header
echo "<h1>" . "<span>" . "# " . "</span>" . $row['product'] .  "<span>" . " #" . "</span>" . "</h1>";

echo "<div id='item'>"; // div class 'item'

echo "<div class='item_left'>";

echo "<p id='p_desc'>";
echo $row['prod_descr'];
echo "</p>";

echo "<p>" . "<span>" . "&pound" . $row['price'] . "</span>" . "</p>";

echo "</div>";

echo "<div class='item_right'>";

echo "<img src='db/images/".$row['image']."' />";
$showHeader = false;

echo "</div>";

?>

How is this achievable please?

Hi again all,

Why does the foreach loop im doing, put the array values from collection, into seperate table rows rather than 1 row per whole array?



    <?php
        class registration{                    
            public $fields = array("username", "email", "password");
            public $data = array();
            public $table = "users";
            public $dateTime = "";
            public $datePos = 0;
            public $dateEntryName = "date";
            public $connection;
            
            function timeStamp(){
                return($this->dateTime = date("Y-m-d H:i:s"));
            }
            
            function insertRow($collection){      
                    //HERE
                    foreach($this->fields as $row => $value){
                        mysql_query("INSERT INTO $this->table ($value)
                        VALUES ('$collection[$row]')");
                    }
                    
                    mysql_close($this->connection->connectData);
            }
            
            function validateFields(){            

                $this->connection = new connection();
                $this->connection->connect(); 
                        
                foreach($this->fields as $key => $value){
                    array_push($this->data, $_POST[$this->fields[$key]]);
                }
                $this->dateTime = $this->timeStamp();
                array_unshift($this->data, $this->dateTime);                
                array_unshift($this->fields, $this->dateEntryName);   
                
                foreach($this->data as $value){
                    echo "$value";
                }
                
                $this->insertRow($this->data);
            }
        }
        
        $registration = new registration();
        $registration->validateFields();
    ?>




I end up with 3 rows

row 1: username
row 2: email
row 3 : password

rather than row 1:username email password.

Hi good people, i'm vary new in this and i'm having trouble with PHP while writing some project for school and because i find many answers on this forum till now i decide to post this.. so here is my problem:

i tryed some variations of :

Code: [Select]
$k1D = $_POST['dates'];
$kol = $_POST['exams'];
mysql_query(" UPDATE studenti SET '$kol' = '$k1D'
WHERE ID = '3'");

but i'm just getting different errors..

have a database with a column of datatype EM (multiple selection, say apples, oranges, grapes)

I want to have a form with checkboxes for those values (apples, oranges, grapes etc) so one can select a breakfast basket type that contains for example, oranges and grapes.

It would pull from the database those baskets with those selection of fruits (specified in the column 'Fruits', which is a EM datatype column. (I have a multiple selection when entering the values for the column.)

Can it be done? Should I make another table with FruitNames?

Hi I wanted to know how once I have selected and echoed the rows from mysql table how can I get it to number those rows that echo?
etc

1.   echo $variable
2.   echo $variable
3.   echo $variable
4.   echo $variable
5.   echo $variable

Any help is appreciated

Hey guys was wondering if anyone could modify the code below to have $output = 'yes' if the number of rows equal 10, 20, 30, 40, 50, 60, 70, 80......... etc

$dbhost = '******';
$dbuser = ''******';';
$dbpass = ''******';';

$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('MYSQL N/A - Please Contact Admin');

$dbname = ''******';';
mysql_select_db($dbname);

$query="SELECT * FROM documentaryinfo";
$result=mysql_query($query);

$num=mysql_numrows($result);

mysql_close($conn);
?>

Thanks

Hi,

I have a problem regarding counting rows in a mysql table. Here is the code:

Code: [Select]
<?php
require_once('includes/connection.inc.php');
$conn = dbConnect('read');
$check = 'SELECT COUNT(*) FROM images';
$checkRes = $conn->query($check) or die(mysqli_error());
if($checkRes <= 0) { header('Location: empty_blog.php'); // redirect to another page
} else { // do something else... }
?>

The error I'm getting: "Notice: Object of class mysqli_result could not be converted to int in C:\xampp\htdocs\photoblog\index.php on line 6"

Any help is greatly appreciated!

I have a mysql table that looks like this:

id int(11) autoincrement
artist varchar(50)
title varchar(50)

I need to check for any rows that have the same titles.
So for example, if I had the following rows:

1 - Bob - Hello World
2 - Charlie Brown - Theme Song
3 - Joe - Hello World
4 - Joe - Is Cool
5 - Bob - Magic Dude

The query would display Row 1, and Row 3 as duplicates. Any idea how I can do something like this?

Hi Everyone,

I am working on implementing a blog comment system using the query below to display comments. 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

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.

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(); 
                } 
            } 
	

Hi all,

How to split the attribute-options after row 15 so it show attribute 1-15 than split the listing than show row 16-30 in a new column split again and show the next 15 attributes and list them in a new column?
Also how to remove the space (3 mm) between each row

Code: [Select]
echo '<tr><td><ul><li style="list-style: none; "><input type="text" name='.$i.'_quantity value="" style="text-align:right;" size="3">&ensp;';
 echo tep_draw_hidden_field($i.'_id[' . $products_options_name['products_options_id'] . ']', $products_options_array[$i]['id']) . $products_options_array[$i]['text'];  
echo "</li></ul></td></tr>";[code]

I need to display a number(the number is retrieved from the db) in the form input field such that only the last 4 digits is visbile, the remaining can be masked as * or X or whatever is applicable.

I know the last 4 can be obtained as follows:

    Code: [Select]
$number=substr($number,-4,4);
 
But when i hit the submit button the form validates the input field and checks if the number is a valid number of a specific format.
Therefore when I click on the submit button then I should still be able to unmask the masked numbers or do something similar that would help me validate the whole number.

  Code: [Select]
  <input type="text" name="no" value="<?php if(!empty($number)){ echo $number;} ?>">
