PHP - Show Login Name From Array

I wish to get only the last part of each array 'g'
And then show non duplicated 'g'
but in the same order that it was in the original array.


Code: [Select]
<?php
$formarray = array(
'name' => array(
      'i1'=>      array('a'=>'a1', 'b'=>'b1', 'c'=>'c1', 'd'=>'d1', 'e'=>'e1', 'f'=>'f1', 'g'=>'g1'),
      'i2'=>      array('a'=>'a2', 'b'=>'b2', 'c'=>'c2', 'd'=>'d2', 'e'=>'e2', 'f'=>'f2', 'g'=>'g2'),
      'i3'=>      array('a'=>'a3', 'b'=>'b3', 'c'=>'c3', 'd'=>'d3', 'e'=>'e3', 'f'=>'f3', 'g'=>'g3'),
      'i4'=>      array('a'=>'a4', 'b'=>'b4', 'c'=>'c4', 'd'=>'d4', 'e'=>'e4', 'f'=>'f4', 'g'=>'g4'),
      )
);

foreach ($formarray as $newarray => $a) {
?><strong><?=$newarray;?></strong><br><?
  foreach ($a as $key => $k) {
?>"<?=$key;?>", <?
foreach ($k as $b) {
//if ($k['DBfield'] != "") {
?>"<?=$b;?>", <?
//}
}
?><br><?
} //end of second foreach
?><br><br><br><?
} //end of first foreach
?>

I need to find out how many times the "mac" key show is in an array.

Code: [Select]
Array
(
[serial] => Robert
[added] => Peter
[mac] => 1232091823
[mac] => 7538572375
[mac] =>943820348239804
[place] =>home
)

I have users in my database with many stored points ie age, gender, interests etc. about 20 points in all.   I have a table of products that I want to recommend only applicable products. They each have saved like minage, maxage, gender, interest etc for the ideal consumer. ie dress gender=f   This is the bare bones of what I have so far:

$result = mysql_query("SELECT * FROM user_table WHERE hash='$session_id'");
$rowuser = mysql_fetch_array($result);

$result = mysql_query("SELECT * FROM products");
$rowproducts = mysql_fetch_array($result);

So now I have $rowuser['gender'] = m , how do I remove all from $rowproducts where gender = f?   Is there a best way to do this knowing I have about 20 points to go through before I am left with an array with just the best selection of products for this user in it?

hi

Hello guys,

Is there on web any updated tutorial on how can I add Facebook login on my simple php login script?

Hi guys.

What I want to create is really complicated. Well I have a login system that works with post on an external website.
I have my own website, but they do not give me access to the database for security reasons, therefore I have to use their login system to verify my users.
What their website does is that it has a post, with username and password. The POST website is lets say "https://www.example.com/login".
 If login is achieved (i.e. username and password are correct), it will redirect me to "https://www.example.com/login/success" else it will redirect me to "https://www.example.com/login/retry".

So I want a PHP script that will do that post, and then according to the redirected website address it will return me TRUE for success, FALSE for not successful login.

Any idea??

Thanks

How to add the ability to login with username or email for login?

	$result = mysqli_query($conn, "SELECT * FROM users WHERE email = '" . $email. "' and pass = '" . md5($password). "'");

I want to show a cookie of a referral's username on a sign up page. The link is like this, www.mysite.com/signup?ref=johnsmith.

The cookie doesn't show if I go to that url page. But it does show up once I reload the page.  So I'm wondering if it's possible to show the cookie the first time around, instead of reloading the page?

Here is my code.

// This is in the header
$url_ref_name = (!empty($_GET['ref']) ? $_GET['ref'] : null);

if(!empty($url_ref_name)) {

  $number_of_days = 365;
  $date_of_expiry = time() + 60 * 60 * 24 * $number_of_days;
  setcookie( "ref", $url_ref_name, $date_of_expiry,"/");

} else if(empty($url_ref_name)) {
  if(isset($_COOKIE['ref'])) {
    $user_cookie = $_COOKIE['ref'];
  }
} else {}

// This is for the sign up form
if(isset($_COOKIE['ref'])) {
  $user_cookie = $_COOKIE['ref'];
  ?>
  <fieldset>
    <label>Referred By</label>
    <div id="ref-one"><span><?php if(!empty($user_cookie)){echo $user_cookie;} ?></span></div>
    <input type="hidden" name="ref" value="<?php if(!empty($user_cookie)){echo $user_cookie;} ?>" maxlength="20" placeholder="Referrer's username" readonly onfocus="this.removeAttribute('readonly');" />
  </fieldset>
  <?php

I am displaying rows from a database onto a page using:

while($row=mysql_fetch_array($query)){

echo $row['name'];

}

I need to figure out how to limit the rows shown to the page to 100. And if there are 100 rows on the page, a link will be displayed at the bottom, that says "Next 100". Then this will display the next 100 rows.
Can you give an example how to do this please?

Thanks

Hi everyone i wonder if you can help me he

I need a script for a login and check login- create cookie.

Here is my form:

<form method="post" action="check_login.php">
<p>
<input type="submit" name="Submit2" value="go" />
</fieldset>
</p>
</form>

that sends it to check_login (which BEFORE i deleted something by accident, used to take me to a username and password box)

But now all it does is send me straight to the memebrs area???

Hello, I am once again desperately asking for your help,

I am working on a simple login page and I am having trouble actually getting it  to login. I display error messages for if the user doesn't enter anything but I can't seem to get it to work for if the credentials are wrong. It logs the user in whether the information is right or not and i dont even know what to do now

 

This is the code any suggestions would be greatly appreciated

Rules →

• There are 9 Columns(C1,C2,C3,C4,C5,C6,C7,C8,C9) [ Max columns will be 9]

• The number of Rows can vary from 3,6,9,12,15,18 (Max). In this case Number of Rows shall be 12

Number of Rows = No of Tickets (Max Allowed 6) x Rows Per Ticket (Max Allowed 3). Thus, Max Rows can be 18

• Each Row is required to have 4 Blank Spaces and 5 Filled with Numbers

• All numbers available in the Column Array have to be utilized

• This configuration of an shall create a matrix of 9 Columns & 12 Rows (3 x 4 Tickets), which is 108 MATRIX BLOCKS where only a maximum of 60 numbers can be filled out of 108 available blocksrandomly with the above conditions being met 100%.

• The numbers in column must be arranged / sorted in ASCENDING ORDER (For coding logic purpose, as soon as the number is assigned to the new MATRIX MAP use array_shift() or unset() the number so as to avoid repetition

Example - Row 1 and Column 1 shall generate a MATRIX BLOCK - R1C1

Row 3 and Column 7 shall generate a MATRIX BLOCK - R3C7

Matrix Block can also be termed as Matrix Cell for your ease (if needed)

MASTER SET OF ARRAY WITH NUMBERS

array( "C1"=> array( 1, 2, 3, 5, 6, 7, 9 ), //7 Numbers "C2"=> array( 13, 14, 15, 17, 18, 19 ), //6 Numbers "C3"=> array( 21, 22, 23, 24, 25, 26, 30 ), //7 Numbers "C4"=> array( 31, 33, 34, 36, 37, 38, 39 ), //7 Numbers "C5"=> array( 41, 42, 46, 47, 48, 49, 50 ), //7 Numbers "C6"=> array( 51, 52, 53, 54, 55, 57, 58 ), //7 Numbers "C7"=> array( 61, 62, 64, 65, 69, 70 ), //6 Numbers "C8"=> array( 71, 74, 75, 76, 77, 78 ), //6 Numbers "C9"=> array( 82, 83, 85, 87, 88, 89, 90 ) //7 Numbers );

The above array has 60 Numbers to be filled out of 108 MATRIX BLOCK / CELL which meets the condition that for a FULL BLOCK containing 4 MINI BLOCKS WITH 3 ROWS (max. allowed) EACH

I have been able to generate this without any issue meeting all the conditions of the Columns

My Allocation Matrix Array will look like

array( "R1"=> array( "C1"=> true, // Means that MATRIX BLOCK R1C1 will be NOT EMPTY "C2"=> false, // Means that MATRIX BLOCK R1C2 will be EMPTY "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> false ), "R2"=> array( "C1"=> false, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> true, "C8"=> true, "C9"=> false ), "R3"=> array( "C1"=> true, "C2"=> true, "C3"=> true, "C4"=> true, "C5"=> false, "C6"=> false, "C7"=> false, "C8"=> false, "C9"=> true ), "R4"=> array( "C1"=> true, "C2"=> true, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> false ), "R5"=> array( "C1"=> false, "C2"=> false, "C3"=> false, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> true, "C8"=> true, "C9"=> true ), "R6"=> array( "C1"=> true, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ), "R7"=> array( "C1"=> false, "C2"=> false, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> true ), "R8"=> array( "C1"=> true, "C2"=> false, "C3"=> false, "C4"=> true, "C5"=> false, "C6"=> false, "C7"=> true, "C8"=> true, "C9"=> true ), "R9"=> array( "C1"=> true, "C2"=> false, "C3"=> true, "C4"=> false, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ), "R10"=> array( "C1"=> false, "C2"=> true, "C3"=> true, "C4"=> true, "C5"=> true, "C6"=> false, "C7"=> true, "C8"=> false, "C9"=> false ), "R11"=> array( "C1"=> false, "C2"=> true, "C3"=> false, "C4"=> true, "C5"=> true, "C6"=> true, "C7"=> false, "C8"=> true, "C9"=> false ), "R12"=> array( "C1"=> true, "C2"=> false, "C3"=> true, "C4"=> true, "C5"=> false, "C6"=> true, "C7"=> false, "C8"=> false, "C9"=> true ) );

In the above array R stands for Row, C for Column, TRUE/FALSE (Boolean) means that if TRUE a Number can be filled in the resulting MATRIX BLOCK / CELL ( Row[Number]Column[Number] ) else if FALSE the MATRIX BLOCK / CELL shall be EMPTY

The result for the above shall be

PROBLEM : 

I am unable to understand what should possibly be the logic & loop used here for creating a MATRIX ALLOCATION MAP as shown above

I have tried while, foreach & for but unable determine the perfect combination which would meet the conditions.

(Tried all of the above with Nested Loops also)
