Adding onto the value of a $_SESSION

[Logician]

Is it possible to add onto the value of a $_SESSION, rather replacing it?

 

$_SESSION['order']['cartcontenttext'] += echo 'Small: "'.$content['sizes'].'"';
$_SESSION['order']['cartcontenttext'] += echo 'Medium: "'.$content['sizem'].'"';
$_SESSION['order']['cartcontenttext'] += echo 'Large: "'.$content['sizel'].'"';

 

... so the result would be something like this:

echo $_SESSION['order']['cartcontenttext'];

Small: 1Medium: 3Large: 2

Yes, but there is no need for echo or all the unnecessary quoting.

 

$_SESSION['order']['cartcontenttext'] .= echo 'Small: ' . $content['sizes'];

[phporcaffeine]

$_SESSION['order']['cartcontenttext'] = "Some additional text at the beginning " . $_SESSION['order']['cartcontenttext'];
$_SESSION['order']['cartcontenttext'] = $_SESSION['order']['cartcontenttext'] . " Some additional text at the end";

$_SESSION['order']['cartcontenttext'] = 'Small: ' . $content['sizes'] . ' Medium: ' . $content['sizem'] . ' Large: ' . $content['sizel'];

(You could add line breaks ("/n") or HTML break tags ("<br />"), if you didn't want it in a single line)

Thorpe, I tried your suggestion, but it didn't work and I didn't get an error message in my log:

 

foreach ($_SESSION['cart']['content'] as $content) {
	$query = "select * from products where id='{$content['id']}'"; $result = mysql_query($query); $row = mysql_fetch_array($result);
	if ($content['sizes'] == 0) {goto sizem;} else {$_SESSION['order']['cartcontenttext'] .= echo 'Small: '.$content['sizes'];}
	sizem:
	if ($content['sizem'] == 0) {goto sizel;} else {$_SESSION['order']['cartcontenttext'] .= echo 'Medium: '.$content['sizem'];}
	sizel:
	if ($content['sizel'] == 0) {goto sizexl;} else {$_SESSION['order']['cartcontenttext'] .= echo 'Large: '.$content['sizel'];}
	sizexl:
	if ($content['sizexl'] == 0) {goto endsizes;} else {$_SESSION['order']['cartcontenttext'] .= echo 'Extra large: '.$content['sizexl'];}
	endsizes:
}

 

 

I'll try your suggestion, phpORcaffine.

[trq]

Obviously you missed the part about not needing echo.

 

And please, drop the goto's!

[Logician]

Ok, so I tried this. It looks like exactly what I need, but I suspect I have mucked up the braking out?

 

$_SESSION['order']['cartcontenttext'] = '.if ($content['sizes'] == 0) {goto sizem;} else {echo 'Small: '.$content['sizes']; sizem: if ($content['sizem'] == 0) {goto sizel;} else echo 'Medium: '.$content['sizem']; sizel: if ($content['sizel'] == 0) {goto sizexl;} else {echo 'Large: '.$content['sizel']; sizexl: if ($content['sizexl'] == 0) {goto endsizes;} else {echo 'Extra large: '.$content['sizexl']; endsizes:}

 

 

Thorpe, what is wrong with goto's?

[Logician]

This is the code being used in whole:

 

foreach ($_SESSION['cart']['content'] as $content) {
	$query = "select * from products where id='{$content['id']}'"; $result = mysql_query($query); $row = mysql_fetch_array($result);
	$_SESSION['order']['cartcontenttext'] = if ($content['sizes'] == 0) {goto sizem;} else {echo 'Small: '.$content['sizes'];} sizem: if ($content['sizem'] == 0) {goto sizel;} else {echo 'Medium: '.$content['sizem'];} sizel: if ($content['sizel'] == 0) {goto sizexl;} else {echo 'Large: '.$content['sizel'];} sizexl: if ($content['sizexl'] == 0) {goto endsizes;} else {echo 'Extra large: '.$content['sizexl'];} endsizes:;
	$query = "INSERT INTO orders (id, cartcontent) VALUES (null, '".$_SESSION['order']['cartcontenttext']."'";
	mysql_query ($query);
}

[trq]

You seem to missing the absolute basics. If statements do not return values, just like foreach statements do not return any value.

 

I think you should get yourself a book and read it from start to end.

[Logician]

LOL

 

Well, do you have any suggestion as a way to achieve what I am trying to do?

[trq]

Not really. At this point, you really need to learn some basic php and there are plenty of books around that will teach you that.

[Logician]

28,097 posts and nothing to suggest, I'd have to recommend the same.

[trq]

I have given you what I consider to be the most appropriate suggestion. It's not my fault if you won't listen too the advice.

[Logician]

Yes. Fair enough.

 

I am now going to take 2nd best. I've mind hammered myself so much I am temporarily uncapable of detecting minor erros. Could you please help me with this, its not working can I cannot see why right now:

 

$_SESSION['order']['cartcontenttext'] = 'Small: '.$content['sizes'].'Medium: '.$content.'Large: '.$content['sizel'].'Extra large: '.$content['sizexl']';

[trq]

You have an extra quote on the end, otherwise:

 

Define 'not working'.

[Logician]

Defined by PHP refusing to parse the page.

 

The quote on the end is the closing quote is it not?

[Logician]

This was what I needed.

 

$_SESSION['order']['cartcontenttext'] = 'Small: '.$content['sizes'].' Medium: '.$content['sizem'].' Large: '.$content['sizel'].' Extra large: '.$content['sizexl'].'';

[trq]

Why do you insist on adding extra quotes that are simply not needed?

 

$_SESSION['order']['cartcontenttext'] = 'Small: '.$content['sizes'].' Medium: '.$content['sizem'].' Large: '.$content['sizel'].' Extra large: '.$content['sizexl'];

 

What do you think the quotes on the end of your last post are actually for? They do nothing.

[Logician]

Perhaps, but I have accomplished my desired outcome. That saying if it works don't change it (or something like that I'm too mind smacked), well, yeah that applies now.

[trq]

There is always room for code to be improved.

[Logician]

I have more important things to do my friend, especially as I am 27, unemployed and still living at home.

[trq]

Yeah, that makes sense

Closing quote for what?

 

Here is some basic string handling 101:

 

"Any text in these quotes will echo as typed, however the double quotes have the ability to also echo the defined values of variables (i.e $a would echo the value of $a in double quotes)"

 

'Any text in single quotes will echo as typed, and WILL not echo intrinsic value of typed variables, rather the literal value of the variable (i.e $a will echo as $a)'

 

You only need a closing quote and apostrophe when there is a corresponding, opening quote or apostrophe. The PHP interpreter does not require any line terminating quotes or apostrophes. Generally, PHP lines are terminated with a semi-colon ";", except in some cases, where a statement may not complete  on one line (i.e function/method/class declarations ... etc).

 

You should really start by learning the what the difference is between strong and loose typed languages, how PHP is typed (loose as a goose) and then study up on PHP operators and basic control structures.

 

The best way to help some one is to teach them how to find the answer themselves, not do it for them - that doesn't help at all.
