[SOLVED] unexpected elseif

[Foser]

<?php 
start_session();
if (isset($_SESSION['views'])); {
$_SESSION['views'] = $_SESSION['views'] + 1; }
elseif (isset($_SESSION['views']) == 10); {
unset($_SESSION['views']); }
else 
$_SESSION['views'] = 1;

?>

 

I don't understand what is the problem with my elseif command. Looks good to me, I've played arround with it a bit but does not work!

 

Thanks

<?php

session_start();

if (isset($_SESSION['views']) and $_SESSION['views'] < 10) {

$_SESSION['views'] = $_SESSION['views'] + 1; }

elseif (isset($_SESSION['views']) == 10) {

unset($_SESSION['views']); }

else {

$_SESSION['views'] = 1;

}

?>

<?php 
start_session();
if (isset($_SESSION['views']))
{
$_SESSION['views'] = $_SESSION['views'] + 1; 
}elseif (isset($_SESSION['views']) == 10){
unset($_SESSION['views']); 
$_SESSION['views'] = 1;
}

?>

and $_SESSION['views'] < 10  

 

i dont understand why we need this?

 

<?php 
start_session();
if (isset($_SESSION['views']))
{
$_SESSION['views'] = $_SESSION['views'] + 1; 
}elseif (isset($_SESSION['views']) == 10){
unset($_SESSION['views']); 
$_SESSION['views'] = 1;
}

?>

 

and i dont see a difference... Ive played with those {} and it does not work.

[MadTechie]

try this

 

counts to 10 then back to 1

<?php 
session_start(); //<-- corrected

if ($_SESSION['views'] == 10)
{
unset($_SESSION['views']); 
}

if (isset($_SESSION['views']))
{
$_SESSION['views'] = $_SESSION['views'] + 1; 
}else{
$_SESSION['views'] = 1;
}

echo "Views:".$_SESSION['views'];
?>

[Foser]

<?php 
session_start();
if (isset($_SESSION['views'])); {
$_SESSION['views'] = $_SESSION['views'] + 1; }
if (isset($_SESSION['views']) == 10); {
unset($_SESSION['views']); }
else {
$_SESSION['views'] = 1; }
?>

 

well ive fixed a few twicks but in a different order than yours why does it matter that unset is before isset i get a unwanted else command apparenthly :S

 

thanks, just trying to understand php and thanks for the great help so far!~

[MadTechie]

i used unset first to make the isset fail thus setting it back to 1

 

hope that makes sense

[Foser]

thanks, last question then im pressing solve

 

When the script will unset what will it show as an echo on the browser?

[MadTechie]

nothing

 

try this

 

echo $var;

 

as $var isn't set thiers nothing to echo, same when you unset.. it no longer exists (so isset will be false)

 

but

$var="";

 

will echo nothing but isset will be true as it exists but contains an empty string..

 

make sense ?

[Foser]

yea, i got it working now.

but for some reason the season variable isn't going up after a refresh.

<?php 
session_start();
if ($_SESSION['view'] == 10); {
unset($_SESSION['view']); }
if (isset($_SESSION['view']))
$_SESSION['view'] = $_SESSION['view']+ 1; 
else { $_SESSION['view'] = 1; } 
echo "Views: " .$_SESSION['view']. "<br> This will reset after 10 refreshes."; 
?>

 

I checked my very basic season counter and looks like this, can't find the mistake.

[MadTechie]

<?php 
session_start();
if ($_SESSION['view'] == 10);
{
unset($_SESSION['view']);
}

if ( isset($_SESSION['view']) )
//somthing is missing here
{ //Ahh thats better
$_SESSION['view']++; //add's 1 
else {
$_SESSION['view'] = 1;
} 
echo "Views: " .$_SESSION['view']. "<br> This will reset after 10 refreshes."; 
?>

[Foser]

<?php 
session_start();
if ($_SESSION['view'] == 10); {
unset($_SESSION['view']); }
if (isset($_SESSION['view'])) {
$_SESSION['view'] = $_SESSION['view']++; } 
else { $_SESSION['view'] = 1; } 
echo "Views: " .$_SESSION['view']. "<br> This will reset after 10 refreshes."; 
?>

 

It still does not add for some reason :S

[MadTechie]

Oh LOL

 

yeah ; ends a statement

 

see IF you can find the problem

 

try 10 attempts

 

i think thats too many hints

[Foser]

if (isset($_SESSION['view'])); {

 

when i do this  i get

 

Parse error: syntax error, unexpected T_ELSE in C:\WAMP\www\Tutorials\Simple_PHP\SESSIONS\unset_Function\index.php on line 7

[MadTechie]

wrong one

 

If starts a block

 

ie

<?php
if( $a == $b)
{
echo "hello ";
echo "world"
}
?>

 

Quote this post to see the how to fix (or try to find it, as your intrested in learning bug finding is key)

 

if ($_SESSION['view'] == 10); {

to

if ($_SESSION['view'] == 10) {

[Foser]

Great works fine!

 

Thanks a lot for your patience I've learned a lot

[MadTechie]

cool

 

i know that was probably a pain but it helps laters  :-\

 

don't hate me
