For loop troubles

[Guest190829]

I need to make a for loop to access the contents of an array, but I don't know where to put it or if vbulletin has a special syntax for it.

The loop is

for($i=0; $i < sizeof($contents); $i++)

then I access the contents of the array inside a table.

Do I put in the template? Or somewhere else?

Any help will be greatly appreciated. :p

for($i =0 ; $i <= sizeof($contents); $i++) {
$var .= "whatever";
$var2 .= "more Whatever"
}

You'll need to put that in an appropriate php script. Then in your template use $var and $var2 or whatever variables you're calling with the for loop.

[Guest190829]

So every variable that's called must be within the for loop braces?

[Jolten]

If you want the variables to change based on the count, yes. The way I have it coded above with the .= the variable will simply be repeated for each count. so if the count = 4 placing $var in your template would render the word Whatever 4 times. and placing $var2 in your template will render more Whatever 4 times as well.

well the variable i have to access is $contents[$i]->rating

And I tried doing $rating .= $contents[$i]->rating

but that didn't work....

I'm getting the array from an included file, would I have to change all the variables in there from = to .= ?

That looks like you're walking through a file byte by byte in C.

If you have an array look at foreach()...

It's not just a simple array like

array( '1', '2', '3', '4', '5', '6' );

and the actual code to it is not my own because i'm only intergrating it into vbulletin. So a for each loop would be too difficult. :(

I just need to a detail way to access the variable of the array to the templates.


<td> $contents[$i]->rating</td><td> $contents[$i]->runtime</td>

etc...etcc...all works when it's harcoded with the php file, it just the template that messes it up.

I'm gonna guess that you have to put those in singular variables before passing them to a template to be parsed.

[Jolten]

I'd agree with noppid. Put them into singular variables first.

hmm if you use array's ill recommand you to use
the function foreach
or each with combine of list...

[Guest190829]

If you mean singular variables like $ratingcon .= $contents[$i]->rating;

Then I already tried it and it didn't work :ermm:

I'm not too familiar with each and list...

[Jolten]

for($i =0 ; $i <= sizeof($contents); $i++) {
$ratingcon = $contents[i]->rating;
$var .= $ratingcon;
}


no .= when setting the variable

just a possibility. I could be wrong.

[Guest190829]

No luck, still nothing showing up. Anything else? I really appreciate everyone's help.
