I'm trying to add a 'back' link within page.tpl.php (replacing a proper breadcrumb for a certain content type...).
My goal is to create a link that pulls in the current URL, but removes the final argument. So a page mysite/x/y would have a link mysite/x/ (or mysite/x).
Is this possible? (The URLs are aliased).
<?php
$path = ???
$my_link = l('Back', $path);
?>
<?php if (($node->type == 'marketplace_item')): ?>
<div id="breadcrumb" class="nav"><?php print $my_link; ?></div>
<?php endif; ?>
Cheers,
James
if this the case always you can build the URL manually
$my_link = $base_url . arg(0);
or count the args then remove the last one

I want to use PHP only, no jquery to include a page if a div contains the word YES. The reason for this is so that I can use CMS to change the content inside a div from YES to NO to include a page or not. I have tried preg_match, but it searches either a variable or exact phrase in the PHP itself. This is what I am looking for:
<div id="available">YES</div>
<?php if (preg_match("/YES/i", ID="available")) {
include 'page.php';
} else {
echo "Not Available.";
}
?>
I need the ID="available" to search the div id="available" and if YES is found, include the page, if not, echo "Not Available." Thanks for any help.
I figured it out. This will allow you to edit your PHP variable with cushycms to include a page. If the div id="available" is anything other than Yes, the page2.php will not be included on page1.php. The code is attached below.
Page1.php
<h1>This is Page1.php </h1>
<?php
// locate page you want to check div on - page2.php
$content = file_get_contents('page2.php');
// input your specific div id from - page2.php
$first_step = explode( '<div id="available">' , $content );
$second_step = explode("</div>" , $first_step[1] );
// name your variable - in this case - $available
$available = trim($second_step[0]);
// input your output variable - $available and word to match in div - 'Yes'
if(false !== stripos($available, 'Yes')){
// if word in div=id'available' on page2.php is Yes - include page or echo
include 'page2.php';
}
?>
Note: on page2.php for this and cushycms to work, you have to put the div id="available" inside another div to have classes or styles - see example below
Page2.php
<div id="wrapper" class="cushycms">
<div id="available">Yes</div>
</div>
<h2>Please include this rental into the page</h2>
how to print the content in wordpress by passing the string php.I have written the following code but it print all the content including image.I want it to print only particular text.
<?php
$content = get_the_content('Read more');
print $content;
?>
This depends on whether or not you're in the Loop - if you are then your code should work - see more here: https://codex.wordpress.org/The_Loop
However, if you are outside the loop and want to pass in a post ID as a paramter, you can refer to this post as everything is explained very well in there: https://wordpress.stackexchange.com/questions/51741/get-post-content-from-outside-the-loop
$page_id = 302;
$page_object = get_page( $page_id );
echo $page_object->post_content;
Use the_excerpt for only showing small content with read more
<?php $short_desc= get_the_excerpt();
echo substr($short_desc,0,200);?>
I would like to make a custom module with a list of tags. When a tag is clicked the visitor would be navigated to a category page that would show articles with that tag.
I am not a joomla expert, I was thinking about a solution like a hyperlink like this that I would add to the tags inside the module:
href="http://mywebsite.com/index.php/itemlist/tag/tokio%20city?category=places"
Is this possible? Or how could I achieve this result?
Thanks!
This is a bit more complicated than just a query string in the URL as you also need to tweak a template.
If you want to keep it as simple as possible, I'd would recommend creating a new K2 template using template overrides and editing the category template so that it would read the query string parameters and show only articles already filtered by the category and furthermore by the tag via a query string.
That's just a brief how-to, now with a lil bit more details:
1) Create a new K2 template using template overrides.
In your template, if it doesn't exist already, create a folder structure /templates/your_template/html/com_k2/templates/default. The "default" can be replaced with any name if you want to have more K2 templates, but you have to set the new template to each category you have manually.
Now take the content from "/components/com_k2/templates/default" and copy it to the new folder in your template. Now, K2 is using the templates from your /templates/your_template/html/com_k2/ folder. Feel free to google more details if you don't understand template overrides, it's pretty important thing when customizing a template.
2) Edit your category view file to accommodate the list to your query strings
The file that interests you now is in /templates/your_template/html/com_k2/templates/default/category.php. Open this file and try to understand what's important there:
Line 141
<?php foreach($this->leading as $key=>$item): ?>
Line 169
<?php foreach($this->primary as $key=>$item): ?>
Line 197
<?php foreach($this->secondary as $key=>$item): ?>
Line 226
<?php foreach($this->links as $key=>$item): ?>
This is what matters. In these four foreach loops, there are all the items. Then, you can wrap the content of each of these loops into an if-condition to check whether it has the desired tag that is specified in the URL.
To show you an example, this is the code for <div id="itemListPrimary">. You can replace this whole div in the category.php file with the following code and it will work flawlessly. I've just written and tested it.
<div id="itemListPrimary">
<?php foreach ($this->primary as $key=>$item): ?>
<?php
# Get the value of the "tag" query string
$jInput = JFactory::getApplication()->input;
$myTag = $jInput->get('tag', null, 'STRING'); // Joomla 1.6+
//$myTag = JRequest::getVar('tag'); // for Joomla 1.5
# If the tag is empty, the query string is not specified and we'll go standard way without any tag filter
if (empty($myTag)) {
// Define a CSS class for the last container on each row
if ((($key+1)%($this->params->get('num_secondary_columns'))==0) || count($this->secondary)<$this->params->get('num_secondary_columns'))
$lastContainer= ' itemContainerLast';
else
$lastContainer='';
?>
<div class="itemContainer<?php echo $lastContainer; ?>"<?php echo (count($this->secondary)==1) ? '' : ' style="width:'.number_format(100/$this->params->get('num_secondary_columns'), 1).'%;"'; ?>>
<?php
// Load category_item.php by default
$this->item=$item;
echo $this->loadTemplate('item');
?>
</div>
<?php if(($key+1)%($this->params->get('num_secondary_columns'))==0): ?>
<div class="clr"></div>
<?php endif;
# Otherwise the tag is set so we'll filter the articles by the tag
} else {
# Get an array of all the tags that the current article in the loop has
$articleTags = array();
foreach ($item->tags as $tag) {
$articleTags[] = $tag->name;
}
# Check if the article has the tag specified in the URL as a query string
if (in_array($myTag, $articleTags)) {
# Now the default content of the foreach loop comes as written in the default K2 category.php template
// Define a CSS class for the last container on each row
if ((($key+1)%($this->params->get('num_secondary_columns'))==0) || count($this->secondary)<$this->params->get('num_secondary_columns'))
$lastContainer= ' itemContainerLast';
else
$lastContainer='';
?>
<div class="itemContainer<?php echo $lastContainer; ?>"<?php echo (count($this->secondary)==1) ? '' : ' style="width:'.number_format(100/$this->params->get('num_secondary_columns'), 1).'%;"'; ?>>
<?php
// Load category_item.php by default
$this->item=$item;
echo $this->loadTemplate('item');
?>
</div>
<?php if(($key+1)%($this->params->get('num_secondary_columns'))==0): ?>
<div class="clr"></div>
<?php endif;
}
} ?>
<?php endforeach; ?>
</div>
3) Understand how the URLs will work
My typical category URL is:
http://mywebsite.com/category-name
To show only articles with a specified tag, use:
http://mywebsite.com/category-name?tag=your-tag
For instance, if you want to show only articles with the "Tokio City" tag, use:
http://mywebsite.com/category-name?tag=Tokio City
Done.
That's the basics of what you needs. It's all you need if you use primary articles only (no leading and secondary or links). Of course there are plenty more things you might want to take care of:
a notice if there is no article with the specified tag
no redundant code, I've written it like this for the sake of simplicity and readability
SEO - spaces and special characters in URLs
making sure no empty div will be printed
But that would be way more code and I wanted to keep it simple & readable for you. I think I gave you more than enough for a start, so go ahead and get it done, good luck :)
I have the following code to include pages dynamically:
<div id="content">
<div id="aside">
...
</div>
<div id="main">
<?php
$page = (isset($_GET['page'])) ? sanitize($_GET['page']) : 'home';
if (!include 'pages/'.$page.'.php') require 'pages/404.php';
?>
</div>
</div>
As you can see, the #aside has static content.
I want to include a specific content for the #aside depending on the page selected. For example, if the user goes to 'Home' and 'About', I want the 'default' aside. But if the user goes to 'Documents' I want a 'Sections' aside.
I know I can just include each aside from every page, but that's not effective. I also don't want the user to be hable to set the aside as the main content, so they have to be in different folders or something.
I'd like to know an effective and not so complicated way to do this.
Thanks for taking your time to read this.
You want to keep which sidebar goes on which page in a database, and then query that database for the correct sidebar to include.
A table structure may look like this:
Table sidebars: ID | path | name | more info on sidebar...
Table pages: ID | path | name | more info on page...
Table sidebars-to-pages: page_ID | sidebar_ID
This approach even allows you to place multiple sidebars on a specific page.
What if you did this?
<?php
ob_start();
$page = (isset($_GET['page'])) ? sanitize($_GET['page']) : 'home';
if (!include 'pages/'.$page.'.php') require 'pages/404.php';
$contents = ob_get_clean();
?>
<div id="content">
<div id="aside">
<?php include($aside); ?>
</div>
<div id="main">
<?php echo $contents; ?>
</div>
</div>
and $page.php would look like:
<?php $aside = "sidebars/default.php"; ?>
<p>HTML for #main<br />
goes here</p>
There are a few different ways to do this that are all more-or-less equal. I almost always use a config.php file for sites to hold whatever global information I want every page to have. At the top of every page, you just call
<?php
require_once('config.php');
?>
In that config.php file, you could have an array listing your page names and the file you want included for each page, as well as a function that returns the content, like so:
// this lets you call includes relative to the site root
set_include_path($_SERVER['DOCUMENT_ROOT']);
$defaultAsideContent = 'includes/default.php';
$asideContent = array(
'index.php' => 'includes/include-1.php',
'document.php' => 'includes/include-2.php'
);
function getAsideContent() {
global $asideContent;
global $defaultAsideContent;
$content = $defaultAsideContent;
// get the requested page
$pageFull = $_SERVER['REQUEST_URI'];
// strip URL variables
$pageParts = explode('?', $pageFull);
$page = $pageParts[0];
// loop throught the array and see if there is specific aside content for the page
foreach($asideContent as $key=>$value) {
if ($page == $key) {
$content = $asideContent[$key]);
}
}
include($content);
}
Lastly, wherever you want your aside content to show up, just do
<?php getAsideContent(); ?>
When you create a new page, if you want specific aside content, just edit your config file. Just FYI, didn't test this at all, probably has bugs, but you get the jist.
Thank you all for your answers and collaboration. Although none of the answers did exactly what I was looking for, they showed me other ways to approach this issue and guided me to decide what method to use.
I came up with what I think is the simpliest way to do this:
I set my folder structure as: pages/aside and pages/main
I set up an array($asides) with the aside files as the keys and the main content files as the values.
Then I check if the requested file exists in the main folder.
If it doesn't exist, I redirect the user to the 404 page. If it does exist, I loop through $asides to see which aside is asigned to that main content page.
If it doesn't belong to any of the establisged asides, then I include the default aside.
$asides = array(
'aside1' => array('page1', 'page2', 'page3', 'page4'),
'aside2' => array('page5', 'page6')
);
$page = (!empty($_GET['p'])) ? sanitize($_GET['p']) : 'page1';
if (file_exists("pages/main/{$page}.php")) {
foreach ($asides as $key => $value) {
if (in_array($page, $asides[$key])) {
$aside = $key;
break;
}
}
if (!isset($aside)) $aside = 'default';
?>
<div id="aside"><?php require "pages/aside/{$aside}.php"; ?></div>
<div id="main"><?php require "pages/main/{$page}.php"; ?></div>
<?php
} else {
header('Location: ?p=404');
}
The bounty goes to Madara Uchiha because in my opinion, his answer is simple an effective. Thanks again to all of you who helped me with this issue.
Normaly in Drupal 7 we have node.tpl.php:
<?php print render($title_prefix); ?>
<?php if (!$page): ?>
<h2<?php print $title_attributes; ?>>
<?php print $title; ?>
</h2>
<?php endif; ?>
<?php print render($title_suffix); ?>
It is taking $node_url and putting it on a Title in every Node.
I do have 5 nodes (pages) displayed:
First
Second
Third etc
I have created images First.gif, Second.gif and I want to load that images instead of Title.
I did check various implementation, but didn't find any resolution for me.
[Update] I did try to edit template.php file and to add functions for replacing title with image-if images exists. I need this in Drupal 7 - please see here - http://drupal.org/node/221854
Is there any help? Thanks..
Since each node has it's own id then what I'd suggest to you, is to have in your specific files folder images such as node-12, node-13 etc.
In your node.tpl.php
<?php
// path to our file depending on node id
$file = "path/to/file/node-{$node->nid}.gif";
// check if file exists
if (file_exists($file)) {
// theme $title as image with theme_image()
$title = theme('image', array('path' => $file));
}
?>
<h2<?php print $title_attributes; ?>>
<?php print $title; ?>
</h2>
However I'm sure this is not the best way of development but it work for your question.
