help: PHP module - mod_php using str_replace() 3 Years, 2 Months ago Karma: 0  
hi everyone,

I need help using mod_php in my joomla 1.5 site. I want to use this module for finding and replacing some tag on the head section of joomla by using str_replace() and they vary on different pages. The problem is i have little knowledge on PHP but basically this is what i want to achieve, first I want to find the "<head>" tag and insert this "<script src="somejavascript_1.js" type="text/javascript" />" tag below the "<head>" tag.

I'm using a module for the reason i want to insert javascript to specific pages only and I have 3 different javascript that i would insert in different pages of my site.

e.x.
"HOMEPAGE" uses javascrip_1.js
"PRODUCT PAGE" uses javascrip_2.js
"ABPOUT US PAGE" uses javascrip_3.js

If you have some Idea that wouldn't use this technique but would achieve same result. I Open to it!

Thanks guys!

Hi,

All the output from Joomla1.5 is available through:

JResponse::getBody();

And can be changed and modified, then reset using:

JResponse:etBody();

For example:

$body = JResponse::getBody();
$body = str_replace('your string', 'your replacement', $body);
JResponse::setBody($body);
This is better suited for a plugin however, since the module will still display an empty module position.

OK, I'm also a PHP newbie. It makes sense that you would have to actually apply the results after str_replace changed the variable. Would you help me with the syntax of my particular situation? What I'm trying to do is to be able to type something like {username} or <<username>> in the content of a page and have it replace that with the actual username of whichever user is currently logged in. For example, I'd type "Welcome, {username}." and it would display "Welcome, Bob Wenzel." when Bob is logged in. I'm using Joomla 1.5 and here is my code so far:

$user =& JFactory::getUser();
$row->text = str_replace('{username}', $user->username, $row->text);

I assume that looking in $row->text (the content of the article?) is correct, but please feel free to correct me if that is the wrong place. So what would I do to apply the change? Something like:

JResponse:etBody($row->text);

or do I need to setContent or something else? Thanks in advance for your help.

Jacom

Or am I making it too complicated? Would I do it just the way you explained it using the getBody, str_replace, setBody?

Nope, tried that and nothing happened. hmmm.

You will want to use the content plugin: http://www.fijiwebdesign.com/products/joomla-php-plugin.html

Paste your code into the onprepare field. For Joomla1.5 use $article instead of $row. The variable $article (and $row in J1.0) only exist in the content plugins. They do not exist in a module scope.

The problem you had with accessing getBody() is that your module was loaded before the article loaded. It would work if you set the module in a position after the article. It is best however to use the plugin I linked.

Thank you so much for your help. I'm using the botphp_content plugin you suggested and I have this code in the OnPrepare:

$user =& JFactory::getUser();
$article->text = str_replace('<<username>>', $user->username, $article->text);
$article->text = str_replace('<<user>>', $user->name, $article->text);
JResponse:etBody($article->text);

And I have the plugin order set to last, but it's still not working. What am I doing wrong? Do I need to do a getBody before the str_replace or something?
