I have the following code, but I have no idea what I'm doing wrong. Any idea how to fix this?
<?php
if($testing = series_get_meta('code_name')) {
if ($testing == 'Pre1';) {
echo "Pre1";
} elseif ($testing == 'Gem2';) {
echo "Gem2";
} elseif ($testing == 'Remi1';) {
echo "Remi1";
} else {
echo "Default";
}
}
?>
You have a couple typos.
Don't use semi colons in the () of your if/else statements.
You have an extra parenthesis at the end of your last else statement.
Like so:
if ($testing == 'Pre1')
{
echo "Pre1";
} elseif ($testing == 'Gem2') {
echo "Gem2";
} elseif ($testing == 'Remi1') {
echo "Remi1";
} else {
echo "Default";
}
However you task is probably better suited to using a switch() statement like so:
switch ($testing) {
case 'Pre1':
echo 'Pre1';
break;
case 'Gem2':
echo 'Gem2';
break;
case 'Remi1':
echo 'Remi1';
break;
default:
echo 'Default';
}
Hey you have added semicolon inside the if condition, just remove that
<empty>

Trying to use a $_GET within a $_GET
It's not throwing any errors but isn't working the way I want it to. It's been a while since I've done this so I don't know if I'm overlooking something or not. I'm trying to be able to do something like index.php?chatroom&id=1
$pgtitle = '';
$cractive = '';
$dactive = '';
$acactive = '';
$pgChat = '';
if(isset($_GET['chatroom'])){
$cractive = 'active';
if (isset($_GET['cid']) == "1") {
$pgChat == 'Global Chatroom';
}else if(isset($_GET['cid']) == "2"){
$pgChat == 'AK Chatroom';
}else if(isset($_GET['cid']) == "3"){
$pgChat == 'AZ Chatroom';
} else {
echo '<meta http-equiv="refresh" content="0; URL=index.php?chatroom&cid=1">';
}
}else{
header('Location: index.php?dashboard');
}
isset() returns a boolean not the content of the variable, and you was using == instead of = in $pgChat == 'Global Chatroom';, here is an example using your code for something like index.php?chatroom&cid=1:
if (isset($_GET['chatroom'])) {
$cractive = 'active';
if (isset($_GET['cid'])) {
if ($_GET['cid'] == "1") {
$pgChat = 'Global Chatroom';
} elseif ($_GET['cid'] == "2") {
$pgChat = 'AK Chatroom';
} elseif ($_GET['cid'] == "3") {
$pgChat = 'AZ Chatroom';
} else {
echo '<meta http-equiv="refresh" content="0; URL=index.php?chatroom&cid=1">';
}
} else {
echo '<meta http-equiv="refresh" content="0; URL=index.php?chatroom&cid=1">';
}
}
EXTRA: You can do the same thing in that way if you wanna.
$chats = [
'1' => 'Global Chatroom',
'2' => 'AK Chatroom',
'3' => 'AZ Chatroom',
];
if (isset($_GET['chatroom'])) {
$cractive = 'active';
if (isset($_GET['cid']) && isset($chats[$_GET['cid']])) {
$pgChat = $chats[$_GET['cid']];
} else {
echo '<meta http-equiv="refresh" content="0; URL=index.php?chatroom&cid=1">';
}
}

If the phone number matches , I am able to print "Yes". If it doesnot match , i need to print "No". But if i include else part , its executing only else part. Please guide me how and where to write else part.
<?php if($re['phone_v'] == "1"){
echo "Yes";
}else if($re['phone_v'] == "0"){
for($i=0;$i < count($crusers);$i++) {
if ($re['phone'] == $crusers[$i]['phone']) {
echo "Yes";
}
}
}
?>
I am checking condition inside table in view. small thing is making complicated.
This will help you.
$re['phone_v'] = 0;
$re['phone'] = 1;
$crusers[0]['phone'] = 1;
if($re['phone_v'] == "1"){
echo "Yes";
}else{
if($re['phone_v'] == "0")
{
for($i=0;$i < count($crusers);$i++)
{
if ($re['phone'] == $crusers[$i]['phone'])
{
echo "Yes11";
}else{
echo "No";
}
}
}

Im working on a simple roll a dice program. So it has to generate a random number from 0-5 and when it selects 0-4 it echo's and when it selects 5 it echo's.
To it keeps echo the first echo 'you got 6'. I cant seem to get my mind around this.
<!DOCTYPE html>
<html>
<head>
<title>A loop of your own</title>
<link type='text/css' rel='stylesheet' href='style.css'/>
</head>
<body>
<?php
$trows = 0;
$dice = 0;
while ($dice == 0)
{
$dice = rand(0,5);
$trows++;
}
if ($dice = 5)
{
echo 'you got 6';
}
else
{
echo 'you got 1-5';
}
echo '<br><br>';
echo $trows;
?>
</body>
if ($dice = 5)
Is actually assigning the value of 5 to dice, rather than comparing the values, so the first part of the if statement will be entered, rather than the else.
if ($dice == 5)
is what you are looking for
Edit: From your comments I think this is what you are looking for
$trows = 0;
$dice = 0;
while ($dice != 5)
{
$dice = rand(0,5);
$trows++;
if ($dice == 5) {
echo 'you got 6';
} else {
echo 'you got 1-5';
}
echo '<br><br>';
echo $trows;
}
Your if statement is not testing for a condition, but rather performing an assignment and then evaluating the truth of that assignment (which will always be true in this case).
Your code should be:
if($dice == 5)
{
echo 'you got 1-5';
}
Notice the == instead of the single =
This will do the trick
while ($trows == 0)
{
$dice = rand(0,5);
if ($dice == 5)
{
echo 'you got 6';
}
else
{
echo 'you got 1-5';
$trows++;
}
}

im trying to make something to change password.
nkode is the new password
gkode is the old password
if($_GET[rediger] == 'ja'){
$nkode = md5($_POST[nkode]);
$gkode = md5($_POST[gkode]);
if($nkode !== ''){
if($gkode !== ''){
$nukode = $udskrivprofil[Kodeord];
if($gkode == '$nukode'){
echo "success";
} else {
echo "fail";
}
}
}
echo "<br>$gkode <br> $nukode";
}
both $gkode and $nukode outputs the 100% same, yet i get the fail error... whats wrong?
if($gkode == '$nukode'){
Look at those quotes. You're comparing the contents of $gkode against a string which has the characters $, n, u, etc... in it...
Maybe you wanted
if($gkode == $nukode){
instead?
remove quotes from $nukode variable...
if($_GET[rediger] == 'ja'){
$nkode = md5($_POST['nkode']);
$gkode = md5($_POST['gkode']);
if($nkode !== ''){
if($gkode !== ''){
$nukode = $udskrivprofil[Kodeord];
if($gkode == $nukode){
echo "success";
} else {
echo "fail";
}
}
}
echo "<br>$gkode <br> $nukode";
}

I was just practicing and wanted to see if there was a more robust way to write this? Should I use a for loop?
<?php
function recursion($number){
if ($number === 0){
break;
}
else {
$subtracted_number = $number-1;
echo $subtracted_number;
recursion($subtracted_number);
}
}
recursion(9);
?>
//output is 876543210
as you can do it in a simple for loop you won't need your recursion here
function countdown($num)
{
for($i=$num-1; $i>0; $i--)
{
if($i !=0)
echo $i;
}
}
use as:
countdown(9);//echoes 87654321
function recursion($number){
$number--;
if ($number > 0){
echo $number;
recursion($number);
}
}
Just for fun http://codepad.org/4S4BcofG
function recursion($number) {
while ($number > 1) {
$number--;
echo $number;
}
}
