Smarty dynamic variable issue - php

Unfortunately, in my current workplace, I have to use Smarty on a project they had before i was employed.
Anyway, I am trying to call in a Dynamic html title for each category in the app.
So for example, the title used to be pageTitle="{$category} in {$areaname}".
However I now want it to be: pageTitle="{html_title}". Within html_title (from db), is a string, for example: "Monkeys in the {areaname}" Where {areaname} could be "jungle".
When I output the result, I get:
"Monkeys in {areaname}".
So to cut a long story short, its not recognizing the variable. It is treating it as a string. I have googled my head off and can't find an answer. I hate smarty!
Please help!

Couldn't you just do something like
$html_title = preg_replace("/{areaname}/", "jungle", $html_title);
after fetching the title from the database?

PHP: Use a $_GET-Param with multiple other Params within a $_GET-Param

yeah, I know, the title is kind of confusing, but no better title came to my mind.
Here is my problem:
I want to use a link in my application, which would look like this:
localhost/index?jumpto=some_folder/somescript.php?someparam1=1234&someparam2=4321
The problem is that &someparam2 is meant to hang on the second $_GET-Param.
It would be like this:
localhost/index?jumpto=some_folder/somescript.php?someparam1=1234&someparam2=4321
Instead, PHP interprets that &someparam2 hangs on the first $_GET-Param.
localhost/index?jumpto=some_folder/somescript.php?someparam1=1234&someparam2=4321
Does anyone know a solution for this?
I already tried
localhost/index?jumpto='some_folder/somescript.php?someparam1=1234&someparam2=4321'
but of course that didn't work.
I hope you can understand my problem.
Thank you for your time.
You will need to URL encode your string some_folder/somescript.php?someparam1=1234 so that php will not parse & in the query string as a param separator.
use urlencode("some_folder/somescript.php?someparam1=1234");

Create value with specific parts of a text file

Ok, I am working on a flatfile shoutbox, and I am trying to achieve a way to get the username from the flatfile and making it a variable so I can use it to make a call to the database to check if the user is admin so they can delete/ban users directly from the shoutbox.
This is an example line in the flatfile
<div><i><div class='date'>12/08/2012 18:56 pm </div></i> <div class='groupAdmin'><b>Admin</b></div><b>kira423:</b> hiya :D</div>
So I wanna take the username which is kira423 in this case and create a variable such as $shoutname and make it equal kira423
I have tried a google search and looked around on here, but was unable to find an answer, so I am hoping that I can get some insight on how to do this with a question of my own here.
Thanks,
Kira
You should use preg_match for those tasks like this:
preg_match_all('|<div class=\'date\'>(?P<date>.*?) .*<a.*>(?P<user>.*)</a>|i', $data, $matches);
var_dump($matches);
Interating through all array elements:
foreach ($matches['user'] as $key => $user) {
var_dump($user);
}
I think you should just parse each line in the flatfile as HTML (there are simple HTML tags used), just like described in PHP Parse HTML code (or type "php parse HTML" in google). Then you may access the username (kira123) from an array or whatever.
PS HTML is not the best way you can store messages to display. Even CSV seems to be better - it'd be "kira123;date;some text" - it's easier to read and to access each part. When displaying, use the standar decorator pattern.

Echo'ing a "{FORUM_NAME}" and Ignoring the "{}"

I'm looking for something that Is really hard for me to do.. I really tried to search all over the net for Solution, But I couldn't seem to find any. I also tried doing this for hours.
What I'm doing: Making a theme for PHPBB2, Installed a MOD that can include PHP in themes.
What is the problem: When I'm doing {} tags in php, It just can't echo those tags.
Let's say I have a function that creates a Table for me, like that:
CreateMyTable(Name,Size,Color);
I put in the function those strings:
CreateMyTable("{FORUM_NAME}",1000,red);
The title stays blank, I actually want it to echo {FORUM_NAME}.
How can I do this?
P.S: I can't do this
CreateMyTable(?>{FORUM_NAME}<?php , 1000, red);
It's not going to work becuase <? = <!-- PHP --> , ?> = <!-- ENDPHP -->.
Thanks for your help :)
If you look in the PHPbb2 template class, you'll find that the template is simply an evaluated set of PHP using the eval() function. You can either print the contents of the PHP before it is parsed using eval() and then use the variable name that the template gives, IE something like (which may not work depending how your template is setup):
CreateMyTable(((isset($this->_tpldata['.'][0]['FORUM_NAME'])) ? $this->_tpldata['.'][0]['FORUM_NAME'] : '' ),1000,randomcolor());
Please note, in order to do it similar to the way above you'd actually have to insert this into your template class.
An much better solution is to avoid using the mod that allows PHP in templates and use JavaScript in the templates to create the function, then print a call to that JavaScript function.
This will work:
CreateMyTable(FORUM_NAME,1000,red);
I also noticed that red is used without quotes - is this also a constant? If it's a variable it needs to have a $ in front of it. If it's a string it should be between quotes.
CreateMyTable(FORUM_NAME,1000,"red");

Changing/deleting html from file_get_contents

I'm currently using this code:
$blog= file_get_contents("http://powback.tumblr.com/post/" . $post);
echo $blog;
And it works. But tumblr has added a script that activates each time you enter a password-field. So my question is:
Can i remove certain parts with file_get_contents? Or just remove everything above the <html> tag? could i possibly kill a whole div so it wont load at all? And if so; how?
edit:
I managed to do it the simple way. By skipping 766 characters. The script now work as intended!
$blog= file_get_contents("powback.tumblr.com/post/"; . $post, NULL, NULL, 766);
After file_get_contents returns, you have in your hands a string. You can do anything you want to it, including cutting out parts of it.
There are two ways to actually do the cutting:
Using string functions like str_replace, preg_replace and others; the exact recipe depends on what you need to do. This approach is kind of frowned upon because you are working at the wrong level of abstraction, but in some cases it has an unmatched performance to time spent ratio.
Parsing the HTML into a DOM tree, modifying it appropriately (this time working at the appropriate level of abstraction) and then turn it back into a string and echo it. This can be more convenient to work with if your requirements are not dead simple and is easier to maintain, but it typically requires more code to be written.
If you want to do something that's most naturally expressed in HTML document terms ("cutting out this <div>") then don't be tempted and go with the second approach.
At that point, $blog is just a string, so you can use normal PHP functions to alter it. Look into these 2:
http://php.net/manual/en/function.str-replace.php
http://us2.php.net/manual/en/function.preg-replace.php
You can parse your output using simple html dom parser and display olythe contents thatyou really want to display

Setting language for user

I would like my php website to be able to be multilinguistic. I thought of using:
echo $lang[$_SESSION['lang']]['WellcomeMessage'];
but I found that I will be needing to format the text, say for example male/female or putting some values from the DB. So I thought that simple strings might not do the trick for formatting?
I know #define might have worked in C as the string translates to code, but I don't know how php does that. For example:
define ($lang['en']['credit_left'],'you have $credits_left');
define ($lang['sp']['credit_left'],'tienes $credits_left creditos mas');
Any suggestions?
