I need to reference a particular functions.php file, that can be stored in the template directory of my Joomla template. WordPress seems to include this, but if I do something like:
Include the functions file
<?php require_once ( 'functions.php' ); ?>
In the functions.php:
<?php
function displaySomething() {
echo "Hello World";
}
?>
and then in the templates index.php:
<?php displaySomething(); ?>
The template breaks/is blank. For aguements sake, I just want to have a single referencable php case function.
Try this -
<?php require_once ($this->baseurl.'/templates/'.$this->template.'/functions.php'); ?>
However, chances are that you shouldn't do it this way. In general it's not a good idea to hard code anything in to your template because that removes the ability to select the pages that you want the code to be executed on and it removes the ability to easily edit what ever the code is doing.
You really should put your code in a module or plugin. Putting it in a module makes it easy to select the pages you want the code on, turn it on or off globally, or to change the output easily. Putting it in a plugin would make it easy to put it on pages based on one of the Joomla event triggers, and to turn it on or off globally.
For the amount of time it would take to turn it in to an extension, it is well worth it.
Try with (using the constant JPATH_BASE):
<?php
#Loading functions
require_once (
JPATH_BASE."/templates/{$this->template}/functions.php"
);
?>

I am working with wordpress.
I see that in my index.php there is a code called <?php get_footer(); ?> ..and I get it, it's simple. This code will pull footer.php.
It seems to me that the get_footer() is built in to wordpress that pulls anything that is named footer.php.
I have created my own page called page.php.
I want to be able to 'get' this page and show in my php code enabled 'sidebar widget'.
I have tried to paste this code, and I am more that certain that its wrong:
<?php
echo file_get_contents("side.php");
?>
What code would I need if I want my custom page called page.php to be shown?
The WordPress way to load a template file is get_template_part():
get_template_part( 'page' );
// loads page.php from the theme directory.
Note that page.php is a special filename in WordPress themes, this file is loaded as a template if a page is displayed. You should give your file a different name if you want to prevent this.
Details are in the already mentioned template-hierarchy.png
Edit:
After rereading your question: If your page.php is not from a template, but in a folder of a plugin you are developing as a sidebar widget, the also already mentioned include('page.php'); would be the way to go.
page.php is a special page of wordpress. See this diagram.
https://developer.wordpress.org/files/2014/10/template-hierarchy.png.
The wordpress way is to create a own template.
https://developer.wordpress.org/themes/template-files-section/page-template-files/page-templates/
try the following
include ('side.php');
OR
require ('side.php');
you may also use include_once / require_once
Please use require_once or include in php file like below.
require_once('side.php');
or
include ('side.php');
try this,
require( dirname( __FILE__ ) . '/page.php' );
if your page is in same level where is your parent page.
Add this code in your php page
<?php include_once('filename.php'); ?>
There are so many options that you can chose:
You can use get_template_part():
From the Docs: WordPress now offers a function, get_template_part(),
that is part of the native API and is used specifically for reusing
sections - or templates - of code (except for the header, footer, and
sidebar) through your theme.
Other solution is require_once() or include_once().
But if i compare both function include_once() is faster than to require_once() for smaller application.
For better understanding about the require and include you can read this Question.
I tried to include some php files in header.php. I use the script below :-
get_template_part( 'custom/tos_functions');
However get_template_part doesn't work for me, so I use include which works fine.
include (TEMPLATEPATH . "custom/tos_functions.php");
The issue is, if I put this line in header.php, I want to use some of the functions in custom template , say profile.php. In profile.php the file is as though not being called at all. I can't get the data I need in profile.php.
Then I tried to take out the include script from header, and place it in profile.php and the data I need can be called perfectly fine.
This will be an issue as there will be many custom php pages I need to create, thus every page will call the include script.
Question, why is it that the file cannot be called from header.php ? The data can only be retrieved within header.php and any custom page that calls the header, couldn't get the data from the include file.
Anyway I can fix this so that I can place the include file in the header.php?
Thank you!
Rather than including files in the theme template files (such as header.php), you should include them in the theme's functions.php file.
Including them in the template files is almost always too late in the WP run for it to be useful, and it may cause unexpected results and unexpected output in your templates.
Instead, in your functions.php file, do something like so:
require_once 'custom/tos_functions.php';
Then, your API code is available where you need it, and it is in the "right" place and consistent with the "WordPress way".
Is there an easy way to change the WP default template hierarchy?
For instance;
Say I want to change my theme directory structure so that it completely changes from the Template Hierarchy suggested here based upon conditionals:
http://codex.wordpress.org/Template_Hierarchy
if I wanted to make sure that for all page types (is_single() is_home() etc) it always opens one template file which then instigates my own pattern to provide the output?
Thanks very much!
I would do it like this:
Easy to read and works well
single.php:
<?php include_once('template-you-want.php');
home.php:
<?php include_once('template-you-want.php');
If you don't want to have these two files at all do it in index.php:
<?php
// at the very top
if (is_single()){
include_once('template-you-want.php');
die(); // don't continue
}
if (is_home()){
include_once('template-you-want.php');
die(); // don't continue
}
I want to create a php page on the website (CMS Wordpress), but I do not understand how to incorporate the template files, for example
<?php get_header(); ?>
And other content. I know that it is possible to create pages through the admin interface, but I do not fit... if you try to create a page of template files and then go for it the direct link:
http://local/wp-content/themes/mytheme/mypage.php
with pre-embedding the code
<?php get_header(); ?>
it will fail like:
Fatal error: Call to undefined function get_header()
What should I do?
How i can "say" this CMS that the page is important for me, and it performs some functionality? That is, in fact, get the full url to her and that did not give out errors…
You need to include wp-load.php in your script to use any of WP functions:
<?
require_once('../../../wp-load.php');
get_header(); ?>
try that. xD
I want to use the if statement to select specific pages that have <body class="section-category"> and output custom content for only those pages.
My PHP is not very good and I hope this is a very simple task to do. Can anyone give me a tip?
I would not check for the existence of a certain body class. Those classes are only the results of other if-else logic and they can easily be overridden or altered, breaking your page template. It's better to check the values those classes are based upon. If I were you, I would try to figure out how this body class was generated and re-use that code.
For example, if your theme's template.php does something like this:
$body_classes[] = 'section-' . form_clean_id(arg(0));
Then I would put this in my template.php:
<?php if (form_clean_id(arg(0)) == 'category'): ?>
// Do fancy stuff!
<?php endif; ?>
It sounds like you want a flag available for certain pages; one that you can read out and act upon in your theme.
In template.php:
function YOURTHEME_preprocess_page(&$vars) { //Many themes already have this function implemented
if (stripos($vars['foo-bar'], 'section')) {
$vars['is_section'] = TRUE;
}
else {
$vars['is_section'] = FALSE;
}
}
Then in your page.tpl.php
<?php if ($is_section): ?>
<p>I am in a section</p>
<?php endif; ?>
That way you keep logic where it belongs: in the preprocessors. And you keep logic out of the template, where it most certainly does not belong!
The if (stripos($vars['foo-bar'], 'section')) { can most probably be made a lot smarter, if you do a var_dump($vars) there, all available variables will dump on your screen (browser). I am certain you will find a variable that you can check against, and that is less 'fuzzy' then a body class. After all: that class is meant for one thing only: to serve as class in the body-tag. And not for checking if you are in some section.
You have the full Drupal available there too, so you can even use any function that (e,g, the section) modules provide.
I would look into a module like Context or Panels to do this- it will serve you better in the long run than coding it in.
