I am completely new to PHP (2 weeks) and I have created a simply script for Joomla that will save parameters from my my admin area options and put those values into a CSS format and save the file. It's a whole long script of CSS but here's an example of it...
<?php
ob_start();
?>
<?php
////////////// Custom colours set from the admin panel
if ($this->params->get('templateColor'))
{
?>
/* <?php echo($template); ?>: Custom Auto-Generated CSS Colors As Set in Admin Template Parameters */
body.site {
border-top: 3px solid <?php echo $this->params->get('templateColor');?>;
background-color: <?php echo $this->params->get('templateBackgroundColor');?>
}
<?php
}
?>
<?php
$googlefontcss = ob_get_contents();
ob_end_clean();
file_put_contents('templates/'.$template.'/css/googlefonts.css', $googlefontcss);
?>
Heres my problem, all of these things are stored in a helper file which is called from my index file, but this has the effect that the CSS file is created every time that the page is loaded rather than when I adjust and save my params in the backend. Surely, if I got a lot of traffic, this is going to stress the server even though the css file is quite short (its longer than shown here).
Being a newbie, I have no idea how I would avoid this problem and instead only have the file written when the options are changed and saved. Anybody suggest a better way?
I'm really confused about why you would do this at all. First, Joomla has a way to save parameters for a template and to use them, which you are doing. It also has a standard way to include a css file in your template. You can do this easily with a plugin if you don't want to addStyle() directly to the the template file. Also for google font api just look at how protostar does it.
I really think you need to look at how templates work in Joomla --- it's not modifying the core to modify your template index unless you are using one of the included templates --- in which case copy it, which you can do with one click in 2.5 and 3.
If you really absolutely have to do this, make a plugin. There are a lot of examples in the JED of plugins to include a file in a template. http://extensions.joomla.org/extensions/core-enhancements/coding-a-scripts-integration/head-code

i need to parse the final output contents (html) of all the pages of this CMS, (using PHP and my own class)
something like:
<?php
echo get_magento_output();
to:
<?php
echo parse_content(get_magento_output());
Can i create an extension that do this? if not, what files i must modify to modify the output in all pages?
To answer your question, yes, you can do it here:
magento/app/design/frontend/enterprise/themename/template/page/1column.phtml
subbing in 1column for whatever the name is for you. However, I would beg you not to do this. If you want to modify things on all pages, change the theme or template. Theres tons of documentation out there on Magento Themes, and there are plenty of places you can alter phtml files to change your output to be correct the first time around.
as example, we have the default header:
/app/design/frontend/enterprise/default/template/page/html/header.phtml
If you want to change css classes, of header for example, change:
<div class="header">
to
<div class="my-new-header">
the phtml functionality is strong, and you can accomplish a lot in these files.
i want to put variable inside css but i don't know how to do it. I have created a php file named style.css.php containing this simple example:
<?php $background = 'blue'; ?>
<style type="text/css">
body {background: <?php echo $background; ?>;}
</style>
But is this a good method? I need to create a customizable theme. The other universal stylesheets are in a normal css file.
Please help.
This question already has an answer.
By the way these link will help you to implement php inside css:

How do i run PHP inside CSS
I think your approach is already good enough, I'm guessing you are including your style.css.php in the head, potentially putting a lot of CSS there, which isn't necessarily a bad thing.
You don't really have to include your CSS files if you need them on every page anyway, putting them directly into the file saves a HTTP Request but makes your file bigger - but bigger file size doesn't matter if you would load the css file anyway. This way you have even finer control over what gets loaded and what does not, which usually shouldn't be necessary.
I am trying to make some changes to PHP files in Wordpress, but it is taking me a long time to find which PHP file to edit. Is there a way to know which PHP file generated a given page?
Thanks!
More information:
I understand the basic outline of Wordpress templates like header.php and single.php. However, I am having a hard time walking through the many theme-specific template files and finding which one serves what purpose. Specifically, I am looking at a generated webpage and attempting to edit it. And I am resorting to inserting tags inside each of the probable template files until I find the right one. Is there a way, perhaps through dev-tool, to see which php file generated the DOM?
It is possible to get a list of all the included files through the get_included_files() function in PHP.
Here is a PHP script to set in the footer.php file of your template :
// echo '<!--'; // you can display this code or show it in an HTML comment
$files = get_included_files();
if ($display_only_theme_files === true) {
$theme_folder = get_template_directory();
foreach ($files as $key => $file) {
if (strstr($file, $theme_folder) === false) {
unset($files[$key]);
}
}
}
print_r($files);
// echo '-->'; // you can display this code or show it in an HTML comment
This script will show you all the included files related to your template. In other words, you will have the possibility to know which file template is used.
Please, be sure to use this code only on your development mode and to delete it when you will be in production.
It is sometimes difficult trying to work out which template file within a theme is being used. First thing worth considering is the Wordpress template hierarchy. This page from the Codex and in particular the diagram should be helpful to you;
http://codex.wordpress.org/Template_Hierarchy
Secondly, it can help if you add the body_class method to your theme's header.php. It is designed to allow greater control of CSS through additional specificity, but by viewing the source through your browser dev tools you can quickly look at the classes added to the body tag and work out which template is being used;
http://codex.wordpress.org/Function_Reference/body_class
How about putting a unique HTML comment in each template file?
I was hoping someone could help. I have just started to dabble with PHP includes for time saving in the future. For example I want to change the footer and header on a web page once (using include) instead of copying and pasting the code 30 or 40 times - oh no... a typo start again.
Which brings me to the question(s) where is it best to place this script?
<?php include("includes/headernav.html"); ?>
Can it be placed in a div, or should it be placed at the top of your code under the body?
If I want to make an image/banner include module. Can I
<?php include("includes/image.jpg"); ?>
Or is best to wrap the image in html and apply like this?
<?php include("includes/imagewrapped.html"); ?>
Do not include .jpeg files directly, use a wrapper. Only use include with other PHP files.
As for including the header, do it any way that feels natural as long as it produces valid html. There is no particular reason to declare another div element.
Hope this helps:
<?php include("includes/ui_header.php"); ?>
My page content between header and footer
<?php include("includes/ui_footer.php"); ?>
You can probably save this as a function and call that function wherever you want to display.
It doesn't matter whether you put include in any place. However, it's better to put include in the top or bottom of your code
While including headers/footers/menus on the site, please keep in mind following things:
1) Your header/footer includes(blocks) should be wrapped inside a div.
2) This way then can be differentiated and any new change to them can be done easily.
3) Its always a good practice to include a wrapper div around an element as CSS can use it for styling.
4) Your header/footer includes (blocks) should have a flexibility that even we place them in header,footer or any sidebar, they should not disturb the UI.
1) Because you are including the HTML file, you probably need to include it where you want to display it.
2) Create a function in php where you send only image URL (maybe some other parameters) and function returns the HTML code (String) which you only echo on page where you want to display it. This way you can ensure, that all images will have the same code and styling.
for example
function generateImage($url=null) {
if (isset($url)) return '<img src='.$url.' style="width: 100px; height:100px; border: 1px;" />';
else return false;
}
The better way is to include always a php file.
Am sure the question is vague.
Let me try to explain.
Assume zend frame work - PHP - jquery combination.
I include jquery files in layout.phtml.
i include some files in controller.php.
some file in view.phtml
Atlast when i run and view the page . Is there any way or any tool to find which file is included through which file (layout controller or view) ??
In addition can some one explain which is the best way include js files and where . using zend framework in layout or controller or view
The only way to find where a public, static asset (JS, CSS, image, etc) is included is to trawl through the source code (using something that can "find in files" would save time).
In regards to how and where to include such assets... for global includes (common stylesheets, scripts, etc), include these in your layouts.
For specific page includes, place these in your views.
The best way to include a static asset is using the appropriate view helper. These are generally displayed in your layout file, for example
<?php echo $this->doctype() ?>
<html>
<head>
<?php
echo $this->headMeta()->prependHttpEquiv('Content-Type', 'text/html; charset=' . $this->getEncoding());
// I use "prepend" here so it comes before any page specific stylesheets
echo $this->headLink()->prependStylesheet($this->baseUrl('/css/common.css'));
echo $this->headScript();
?>
</head>
<body>
<!-- content -->
<?php echo $this->inlineScript() ?>
</body>
</html>
You can then add to these placeholders in your view scripts, for example
<?php
// index/index.phtml
$this->inlineScript()->appendFile('https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js')
->appendFile($this->baseUrl('/js/my-jquery-script.js'));
To "include" a file means very different things in PHP (where it is analogous to copying and pasting source code from another file into the current file) and HTML/JavaScript (where you are referencing another file, which the browser must make a separate HTTP request to download). What do you consider "including"? Are image tags "including" the images? At least we can easily count those references by examining HTTP requests; from the client side, it's impossible to tell what include()s went into the source code behind the rendered output. Even naive source code searching couldn't tell you thanks to autoloading. As is, your question is not well enough defined to provide a clear answer.
Controversal answer:
You don't need that.
If you need that then it's something wrong with the way your designed your application.
Note: I've learned (trial and error) that 90% of things I don't know how to do and that seem to be impossible in ZF are a result of wrong application design.
