This is the code I have so far. I'm trying to use two dropdown menus in my HTML form that contains a 1-5 each and simply add them using POST.
//action for dropdown menu addition
$dropdownValueA = $_POST["dropdown1"];
$dropdownValueB = $_POST["dropdown2"];
$valueone = 0;
$valuetwo = 0;
if ($dropdownValueA == "1a"){
$valueone = 1;
}
if ($dropdownValueA == "2a"){
$valueone = 2;
}
if ($dropdownValueA == "3a"){
$valueone = 3;
}
if ($dropdownValueA == "4a"){
$valueone = 4;
}
if ($dropdownValueA == "5a"){
$valueone = 5;
}
if ($dropdownValueB == "1b"){
$valuetwo = 1;
}
if ($dropdownValueB == "2b"){
$valuetwo = 2;
}
if ($dropdownValueB == "3b"){
$valuetwo = 3;
}
if ($dropdownValueB == "4b"){
$valuetwo = 4;
}
if ($dropdownValueB == "5b"){
$valuetwo = 5;
}
echo $valueone + $valuetwo;
It's totally not clear what is your problem and what is not works as expected. But your code is... not good :) Maybe try something like
if( preg_match('/^([1-5])a$/', $dropdownValueA, $m) ) {
$valueone = $m[1];
}
if( preg_match('/^([1-5])b$/', $dropdownValueA, $m) ) {
$valuetwo = $m[1];
}
echo (int)$valueone + (int)$valuetwo;
If the numbers will always come first, this will be your best option.
$dropdownValueA = $_POST["dropdown1"];
$dropdownValueB = $_POST["dropdown2"];
$valueone = intval($dropdownValueA);
$valuetwo = intval($dropdownValueB);
echo $valueone + $valuetwo;

I am using a for loop on my client's website to insert purchased ticket information into a database. The loop is working correctly, but the client has requested the option to attach a unique identifier to the first entry every time the for loop is run. This identifier would be used to highlight the primary ticket owner when the tickets are printed. I have included the current for loop below for reference. Any ideas on how to achieve this? Thank you.
$threepack = '';
$i = '';
for($i = 0; $i < $tickets; $i++)
{
$firstname = 'firstname'.$threepack;
$lastname = 'lastname'.$threepack;
$address = 'address'.$threepack;
$city = 'city'.$threepack;
$postal = 'postal'.$threepack;
$phone = 'phone'.$threepack;
$altphone = 'altphone'.$threepack;
$sec_firstname = 'sec_firstname'.$threepack;
$sec_lastname = 'sec_lastname'.$threepack;
$email = 'email'.$threepack;
$table->firstname = $data->$firstname;
$table->lastname = $data->$lastname;
$table->address = $data->$address;
$table->city = $data->$city;
$table->postal = $data->$postal;
$table->phone = $data->$phone;
$table->altphone = $data->$altphone;
$table->sec_firstname = $data->$sec_firstname;
$table->sec_lastname = $data->$sec_lastname;
$table->email = $data->$email;
$table->id = 0;
$table->order_total = $data->total;
$table->store();
if($data->tickets == '-1')
{
if($threepack == 2)
{
$threepack = 3;
} else {
$threepack = 2;
}
}
// 8 Fields
if($data->tickets == '5')
{
if ($threepack == '') {
$threepack = 2;
} else {
$threepack += 1;
}
}
}
for ($i = 0; $i < $tickets; $i++) {
// ...
if ($i == 0)
$table->highlightme = 1;
// ...
$table->store();
// ...
}
I have this little tid-bit of my code, which is eventually sent to a MySQL database. The rest of the code is sound, but this code likes to give me empty data some of the time. Is there any way to prevent this from happening?
Edit: Here's the whole chunk
//random Species
$sp_one = mt_rand(1,10);
$one_species = "Water Leaper";
//random Genetics
if($one_species == "Water Leaper")
{
$one_gene = mt_rand(1,5);
if($one_gene < 3)
{
$one_genetics = "1";
}
else if($one_gene < 5)
{
$one_genetics = "2";
}
else
{
$one_genetics = "3";
}
}
//random Gender
$one_sex_num = mt_rand(1,2);
if($one_sex_num == 1)
{
$one_gender = "Female";
}
if($one_sex_num == 2)
{
$one_gender = "Male";
}
//Entering it
$sql="INSERT INTO creatures (species, sex, location, genetics)
VALUES('{$one_species}','{$one_gender}', 's1','{$one_genetics}')";
mysqli_query($con,$sql);
First, your if clauses seem a bit redundant. More concise code:
if ($one_gene <3) { $one_genetics = "1"; }
elseif ($one_gene <5) { $one_genetics = "2"; }
else { $one_genetics = "3"; }
This should always return a value - if everything else fails, "3".
Maybe better even:
$one_genetics = ($one_gene + 1) / 2; // integer division
I don't know what you are doing exacly but maby you can take a look at this:
<?php
$animals = array();
$animals[] = array('dog', 78, array('Komondor','Old English Sheepdog'));
$animals[] = array('Drosophila', 8, array('Vestigal','Ebony'));
$number_animals = count($animals) - 1;
$list_size = 30;
for($q = 1; $q <= $list_size; $q++){
$rand = rand(0, $number_animals);
$animal = $animals[$rand];
$number_species = count($animal[2]) - 1;
$rand = rand(0, $number_species);
$randsex = rand(0, 1);
$species = $animal[2][$rand];
$sex = ($randsex ? 'male' : 'female');
$genes = $animal[1];
echo "$q: $species - $sex - $genes <br>";
}
?>

I'm trying to fix something with which I'm not familiar with and don't know how to proceed. The forum on which I'm working is suppose to show under "TOP 50" only the most commented topics (2 pages by 25 topics) but it shows all topics (by 25) without any limitation of the pages. I need only the first 2 pages - but don't know how to get rid of the others?
I'm even not sure that the below code is the responsible one but please have a look and give me a hint if you see any solution.
This is the code:
{
public function __construct()
{
parent::__construct();
}
public function get_forum()
{
if ($_GET['l'] && ($_GET['l'] == 'leng' || $_GET['l'] == 'lrus' || $_GET['l'] == 'lde' || $_GET['l'] == 'ltr'))
$l = substr($_GET['l'], 1);
else
$l = 'eng';
(isset($_GET['num'])) ? $page = intval($_GET['num']) : $page = 1;
$id_user = intval($_SESSION['user_id']);
$lang = language::getLang();
if ($_GET['el']) {
switch ($_GET['el']) {
case 'categories':
return $this->getCategories($l);
break;
case 'top':
$top_lang = $_GET['ln'];
$c = $this->db->selectAssoc($this->db->Select('*', 'forum_categories ,forum_thems', "`forum_categories`.`lang` = '" . $l
. "' AND `forum_thems`.`id_categories` = `forum_categories`.`id`"));
$total_pages = count($c) / 25;
$p = "<div class=\"pageCounter_box\">Pages:";
if (empty($_GET['p'])) {
$_GET['p'] = 1;
}
for($i=1; $i<$total_pages+1; $i++){
if ($i == $_GET['p']) {
$class = 'class="active_page"';
}
$p .= "<a href=\"$top_lang/smoke/{$_GET['l']}/top?p=$i\" $class>$i</a>";
}
$p .= "</div>";
return $this->getTop($l) . $p;
break;
I think you could do a check in there of If ($total_pages > 2) { $total_pages = 2};
$c = $this->db->selectAssoc(
$this->db->Select('*', 'forum_categories ,forum_thems', "`forum_categories`.
`lang` = '" . $l. "' AND `forum_thems`.
`id_categories` = `forum_categories`.`id`"));
$total_pages = count($c) / 25;
if ($total_pages >2) { //limit to two pages
$total_pages = 2;
}
$p = "<div class=\"pageCounter_box\">Pages:";
if (empty($_GET['p'])) {
$_GET['p'] = 1;
}
"thanks a lot - great help! Do you further see why both pages might show active (page counter shows both active) when showing page 1? Page 2 is fine, there only Page 2 shows active..."
The $class variable is staying set, you need to have an else that sets the class to an empty string
for($i=1; $i<$total_pages+1; $i++){
if ($i == $_GET['p']) {
$class = 'class="active_page"';
} else {
$class = '';
}
$p .= "<a href=\"$top_lang/smoke/{$_GET['l']}/top?p=$i\" $class>$i</a>";
}
Basically this is related to a squash application where we have 2 scores. One is from winner point of view and another from loser point of view.
eg.
Score1: 11-5,11-5,11-5 (Winner point of view)
Score2: 5-11, 5-11,5-11 (Loser point of view)
Now in my logic i want to find which is the winner score and which is the loser score.
I have written my logic in the below way and it does work. But i want to know if their is any other better/optimized way of writing this.
$high1 = 0;
$high2 = 0;
$score1 = "2-11,5-11,4-11,4-4";
$score2 = "11-2,11-5,11-4,4-4";
$score1Array = explode(",",$score1);
$size = sizeof($score1Array);
for($i = 0; $i < $size; $i++) {
$checkscore1 = explode("-",$score1Array[$i]);
if($checkscore1[0] < $checkscore1[1]) {
$high1++;
}else if($checkscore1[0] > $checkscore1[1]) {
$high2++;
}
}
if($high1 > $high2) {
$winningScore = $score2;
$losingScore = $score1;
}else{
$winningScore = $score1;
$losingScore = $score2;
}
echo $winningscore;
echo $losingscore;
What about something like this:
function is_winning($score) {
$split_scores = preg_split('/(-|,)/', $score);
$wins = $losses = 0;
for($i = 0; $i < count($split_scores) / 2; $i += 2) {
if($split_scores[$i] > $split_scores[$i + 1])
$wins++;
if($split_scores[$i] < $split_scores[$i + 1])
$losses++;
}
return $wins > $losses;
}
Assuming $score is formatted as in your question. You can then use it like this:
$score1 = "2-11,5-11,4-11,4-4";
$score2 = "11-2,11-5,11-4,4-4";
if(is_winning($score1)) {
$winning_score = $score1;
$losing_score = $score2;
} else {
$winning_score = $score2;
$losing_score = $score1;
}
echo $winning_score;
echo $losing_score;
The idea is to split the score into an array where the even numbered indexes have the left score and the odd numbered indexes the right score. We then count the number of wins and the number of losses. If there's more wins then losses then we return true since the score was a winning score. If there's not more wins then losses we simply return false.
This should work
$score1 = "2-11,5-11,4-11,4-4";
$score2 = "11-2,11-5,11-4,4-4";
$l = $r = 0;
$score1_sets_arr = explode(',', $score1);
foreach ($score1_sets_arr as $set_score) {
$set_score_arr = explode('-', $set_score);
if ($set_score_arr[0] > $set_score_arr[1]) {
$l++;
} else {
$r++;
}
}
if ($l > $r) {
$winning_score = $score1;
$losing_score = $score2;
} else {
$winning_score = $score2;
$losing_score = $score1;
}
you can use this :
<?php
$high1 = 0;
$high2 = 0;
$score1 = "2-11,5-11,4-11,4-4";
$score2 = "11-2,11-5,11-4,4-4";
$explode = explode(",",$score1);
for($i=0;$i< sizeof($explode);$i++){
$explode2= explode("-", $explode[$i]);
if($explode2[0] <= $explode2[1]){
echo $explode2[0]."-";
echo $explode2[1]." ";
}
}
echo "<br />";
for($i=0;$i< sizeof($explode);$i++){
$explode2= explode("-", $explode[$i]);
if($explode2[1] >= $explode2[0]){
echo $explode2[1]."-";
echo $explode2[0]." ";
}
}
?>
for Winner point of view, all big score in left,otherwise in right. so u can just detect the first score.
$score1Array = explode(",",$score1);
$checkscore1 = explode("-",$score1Array[$i]);
if($checkscore1[0] < $checkscore1[1]) {
echo $score2;
echo $score1;
}else{
echo $score1;
echo $score2;
}
Fix: above code is wrong,try this:
$score1value = eval(str_replace(",","+",$score1));
$score2value = eval(str_replace(",","+",$score2));
if($score1value < $score2value) {
echo $score2;
echo $score1;
}else{
echo $score1;
echo $score2;
}
Controller
for ($x = 1; $x <= $numb; $x++)
{
echo $quanoutput = $this->input->post('quanoutput');
$barcodeoutput = $this->input->post('barcodeoutput');
$productsoutput = $this->input->post('productsoutput');
$outward_date=$this->input->post('outward_date');

$warehouse_id =$this->input->post('warehouse_id');

if ($productsoutput=='undefined'){
//$flag3 = $this->cartmodel->cartInsert($barcodeoutput,$quanoutput,$buyprice,$stock,$warehouse,$warehouse_id,$request_id,$outward_date);
} else {
$flag3 = $this->cartmodel->cartInsert($barcodeoutput,$quanoutput,$buyprice,$stock,$warehouse,$warehouse_id,$request_id,$outward_date);
}
}
Try starting your for loops at 0. (ie. j=0) and change the <= to just <.
