Hi folks, i have a complex problem (for me anyway) but i am sure with your help this can be sorted.

Problem number 1: I have a simple while loop, but its only showing 4 results when i know there are 5
I am missing something very simple i know:

$sql = ("SELECT * FROM postcode WHERE unid='1'")or die ('<p>There seems to be a problem, please try again soon.</p>');   
$result = mysql_query($sql,$con);
$row = @mysql_fetch_array($result);

$i=0;
while ($row = @mysql_fetch_assoc($result)){

  echo "newpoints[". $i++ ."] = new Array({$row['lat']}, {$row['long']}, icon0, '{$row['postcodename']}', '{$row['postcodename']}'); \n";

}

What am i missing here?


Problem number 2:

I have a bunch of latitude and longitude codes stored in the database.
On each page there will be a varied amount of these codes used, but with a max of 20.
I need to find the highest number and the lowest number of each lat and long then come up with a code that is in the middle, the idea of this is to center a map.
So for example there will be an array like this:
50.852293  -1.76088
51.252938  -0.76128
51.259583  -0.727168
51.274  -0.837
51.123106  -0.970657

First i need to find the highest number of the first code (51.274) then the lowest number (50.852293)
and then the highest number of the second code (-1.76088) then the lowest number (-0.727168)
Then work out an inbetween code using the highest and lowest codes for each.

Does anyone have a clue how to go about this? I am not the worlds best array technition or mathematician

Hi guys

I'm kinda stuck..so hopefully you guys can lend me a hand

I've got an array containing date elements ("Y-m-d")...

I'm trying to output some data into googlecharts..so i need to count how many elements that are in the array with todays date -1 day, todays date-2 days...todays date -3days etc... Up until a set number of days (for example 7 days, 14 days etc)..

Any advice on how to go about to achieve this?

I'm new at PHP and have a problem.
I have a MySql database with lists of students grouped into classrooms. A typical group is shown in the attached screenshot screenshot.docx. I want to be able to select one or more of the names by using the associated checkbox, and upgrade a student or students into a different group as defined in the radio button list also in the screenshot.
I have the rudiments of the file attached, but I have absolutely no idea how I can post the array so that the records are updated.
Each student has an individual record with a field name userGroup which holds a string nominated by their classroom teacher, such as "year7", "year 8" and so on while they are in one of the several classrooms, but when they leave school this is recorded in a field named noGroup with a value of 0 or 1.
I can post further details as required, but it would be great if someone could help me.

Hi Guys!

Trying to display data in 3 rows horizontally and 25 vertiacally

Code: [Select]
// Print out result
while($row = mysql_fetch_array($result)){
echo "There are ". $row['COUNT(biddersId)'] ." bidders logged.";
echo "<br />";
}



$query = "SELECT * FROM bidders ORDER BY biddersId";

$result = mysql_query($query) or die(mysql_error());

echo "<table border='1'>";
echo "<tr> <th>Bidders</th>";
// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $result )) {
// Print out the contents of each row into a table
echo "<tr><td>";
        echo"<font face= \"calibri\" size=\"3\">";
echo $row['biddersId'];
echo "</br>";
        echo "</td><td>";
       

}

echo "</table>";

Good morning!

I have a two dimensional array, basically a table (see code below). I want to get a value from the array using two methods:
1) Using the row's key:  $NewValue = $MyArray[$UniqueKey];
2) Using the row's index (row number, so to speak): $NewValue = $MyArray[$RowNumber];

The second print statement in the code below does not work. Both print statements should output the same value. Is there an easy way to do this? The table has hundreds of rows and I will not know the key value of row 879 nor can I generate it. So I cannot use array_keys(). And I DO NOT want to start at the first row and count up to the 879th row.

Any clever ideas to share and enlighten?
Thanks!

<?php
// Initialize the array keys and values
$MyArray = array();
$MyArray['first']['col1'] = 'abc'; $MyArray['first']['col2'] = 'def'; $MyArray['first']['col3'] = 'ghi';
$MyArray['second']['col1'] = 'jkl'; $MyArray['second']['col2'] = 'mno'; $MyArray['second']['col3'] = 'pqr';
$MyArray['third']['col1'] = 'stu'; $MyArray['third']['col2'] = 'vwx'; $MyArray['third']['col3'] = 'yz';
$MyArray['fourth']['col1'] = 'a1a'; $MyArray['fourth']['col2'] = 'b2b'; $MyArray['fourth']['col3'] = 'c3c';
$MyArray['fifth']['col1'] = 'ddd'; $MyArray['fifth']['col2'] = 'eee'; $MyArray['fifth']['col3'] = 'fff';
// Two methods to get a value. Second one does nothing.
print"{$MyArray['third']['col2']}</br>";
print"{$MyArray[2]['col2']}</br>";
?>

Please help me. I'm fairly new to php and have been looking for answers on Goog for about two weeks or so with not an answer. This is my first post on a forum of any type.

I have a form on a php page that when submitted sends a value to a confirm php page

Code: [Select]
      <form action='buyconfirmorder.php' method='post'>
      Purchase: <input type='text' name='ask_shares'><br /><br />
      You Will Pay: &nbsp<input type='text' name='ask'><br /><br />
      <input type='hidden' name='postcardname' value='$postcardname'>
      <input type='submit' name='submit' value='Order'>
      </form>
I need to take the users input from the form and subtract each row from a mysql DB one at a time until the users input is down to a remainder and then I need the remainder (I'll be working with the remainder as well).

Code: [Select]
$query = mysql_query("
SELECT * FROM ask, search
WHERE search.id = ask.card_search_id
AND search.card_name = '$postcardname'
ORDER BY ask_price ASC");

The array will be numbers only.

So an example would be:

User input from the form is 100.00

Code: [Select]
   while($rows = mysql_fetch_array($query))
   {
   $ask_price = $rows['ask_price'];
   }
Let's say the array is 50.50, 40.50, 35.00

I need some code to do:

100.00 - 50.50 = 49.50
49.50 - 40.50 = 9.00
9.00 - 35.00 = <0 does not do anything
so remainder = 9.00

would it be something like
Code: [Select]
$new_ask_shares = $_POST['ask_shares'];
//some sort of a loop or array or combo of both
($new_ask_shares - $ask_price);
the numbers are just an example as the actual numbers will be different each time I query my DB.

Thanks in advance

Hello, I have problem durring binding update query. I can't find what is causing problem.

public function Update(Entry $e)
    {
        try
        {
            $query = "update entry set string = $e->string,delimiter=$e->delimiter where entryid= $e->id";
            $stmt = $this->db->mysqli->prepare($query);
            $stmt->bind_param('ssi',$e->string,$e->delimiter,$e->id);

            $stmt->close();
           

        }
        catch(Exception $ex)
        {
            print 'Error: ' .$ex->getMessage();
        }
    }

When I run function update I'm getting next error:Warning: mysqli_stmt::bind_param(): Number of variables doesn't match number of parameters in prepared statement   Can you help me to solve this problem ?

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;} ?>">

The Script:

$desired_width = 110;

if (isset($_POST['submit'])) {
    $j = 0; //Variable for indexing uploaded image

    for ($i = 0; $i < count($_FILES['file']['name']); $i++) {//loop to get individual element from the array
        $target_path = $_SERVER['DOCUMENT_ROOT'] . "/gallerysite/multiple_image_upload/uploads/"; //Declaring Path for uploaded images

        $validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable

        $new_image_name = md5(uniqid()) . "." . $ext[count($ext) - 1];
		$target_path = $target_path . $new_image_name;//set the target path with a new name of image
        $j = $j + 1;//increment the number of uploaded images according to the files in array

                && in_array($file_extension, $validextensions)) {
            if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {//if file moved to uploads folder

Hey, sorry that I am posting this darn image upload script again, I have this almost finished and I am not looking to ask more questions when it comes to this script specifically.   With the script above I have that part where the script should store the ID numbers (the auto_increment column of the table) of the image files inside of one array and then the "implode()" function would get used on the array and then the ID numbers would get inserted into the "image_file_id" column of the "thread" table.   As you can see at the above part the script prints the following:

                    Array ( [0] => 542 )

                    Array ( [0] => 543 )

                    Array ( [0] => 544 )

And I am looking to insert into the column of the table the following:

542, 543, 544

I thought of re-writing the whole image upload script since this happens inside the for loop, though I thought maybe I could be having this done with the script as it is right now.   Any suggestions on how to do this?

Hey

I have a string that looks like the following:
Quote

top-php-tutorials-2.html


I have a script that cycles through each page. The 2 in the quote above is the page number.

How can I extract the number between the - and the .html and replace it with another number?

I've tried
Code: [Select]
substr($engine->selectedcaturl, 0,-6).$v.".html"But then I realised this only works for numbers that are 1 digit long

Any input would be appreciated

hello,  i have a start time and an end time (no dates).  the following works great, except for when the start time is at night, and the end time is in the morning.  im thinking if i can do an if the number is negative, add 24, that it will resolve my issue.

any ideas?

Code: [Select]
$tbilled = $tfinish - $tstart;

hi i am trying to make a payroll calculator script that takes employee info, calculates pay, displays submitted info in a table, stores info in an array, and updates the array when new info is submitted. i have most of these accomplished, i am having trouble with the "store into an array, and update the array when new info is submitted" parts of the project. i am still not very fluent in php so there may be easier ways to achieve what i have so far. any pointers would be a great help, this part has got me stumped.

NOTE - Please read the information first as it contains important information to understand the problem.

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.

I am having some problems getting a query correct. Basically I have two tables, one with listings and another with categories. In the listings table I have a column called shortdescription.

I am trying to pull the shortdescription from the listings table with the query

$shortdesc = array_shift(mysql_fetch_row(mysql_query("select shortdescription from links where category = '".$scat->id."' ")));

The shortdecription display properly on the pages display the listings, however I am getting the following error on any pages that only display the parent categories


Warning: array_shift() [function.array-shift]: The argument should be an array in /home/...path/file.php on line 1462

The listings id numbers begin at 75+ because the initial parent category id ends at 74. The query seems to be searching for listing ids below 75 and spitting out an error because it is not finding them.

Any ideas on how to eliminate this error and/or stop the query from looking for non-existant data?
