I developed a module which can display article details as newsfeed. By clicking that article title user can go to the full article link.
this newsfeed display in main page. but it display the full content of the article.
I want to display only the first paragraph and if there are images it also.
I used here joomla content table introtext column data.
But i want to only display first paragraph and images only.
This is the code i used.
<?php
$db = JFactory::getDBO();
$db->setQuery("SELECT * FROM #__content WHERE catid = 8");
$fullArticle = $db->loadObjectList(); ?>
..........
<?php foreach($fullArticle as $article){ ?>
<ul>
<li>
<h2><?php echo $article->title; ?></h2>
<?php echo $article->introtext;?>
</li>
</ul>
<?php } ?>
can anyone help me?
You need to put a readmore into the article itself, or joomla considers the entire article is introtext. This is where you'll find the read more button which you can split your articles with, in the article editor:

I have a menu of Home About Blog Templates Contact.
There is a table in my database called Categories.
The items in my table are Home About Blog Templates Contact.
These five items are being pulled from my database by my header.php file for my website.
What I want is to be able to click on each category and it display a specific .php file I have.
for instance if I click home it will display my index.php
clicking about displays my about.php
clicking blog displays my blog.php file etc.
I am not sure how to go about this ?
I am following a tutorial on Udemy as a guideline but, I need further assistance.
This is the php code at the top of my header.php file
<?php
include("includes/config.php");
include("includes/db.php");
$query = "SELECT * FROM categories";
$categories = $db->query($query);
?>
This is the code that is pulling my menu from the database
<?php if(isset($_GET['category']) || strpos($_SERVER['REQUEST_URI'] , "index.php") === false) { ?>
<a class="" href="index.php">Home</a>
<?php }else { ?>
<a class="" href="index.php">Home</a>
<?php } ?>
<?php if($categories->num_rows > 0) {
while($row = $categories->fetch_assoc()){
if(isset($_GET['category']) && $row['id'] == $_GET['category'] ){ ?>
<a class="" href="index.php?category=<?php echo $row['id']; ?>"><?php echo $row['text']; ?></a>
<?php } else echo "<a class='' href='contact.php?category=$row[id]'>$row[text]</a>";
} }?>
Essentially, what is going on in this code is when I click home it displays my index.php file and the code in my index.php file display code from another table I have.
However, when I click the about blog templates and contact categories it will only display the contact.php file for each category I have.
Thus, when I click About Blog Templates Contact only the Contact.php file displays.
I need a starting point on how to build on this where I can tell the code if about, blog, templates, contact is click on then display it's respective file.
The question is how do I use the categories in my database as my variables.
I was thinking using else if statements such as else if categories is = about then display. about.php
else if categories is = blog then display blog.php
If there are any free resources or books I can use to figure this out it would be much appreciated.
EDIT
The Table has only is called categories
ID Text
1 About
2 Blog
3 Templates
4 Contact
There no data stored in the table. All the table structure is ID & Text. The Text is being displayed as the menu and each Text has its associated ID. To be clear the HOME button is apart of the menu but, its not in the category table. I hope this is enough information.
Where you have this in the loop's else block:
} else echo "<a class='' href='contact.php?category=$row[id]'>$row[text]</a>";
Note the href has contact.php for all links.
What I believe that your trying to achieve, based on the categories, is:
} else echo '<a class="" href="' . $row['text'] . '.php?category=' . $row['id'] . '">' . $row['text'] . '</a>';
...so that you set the link's file name to match the category name in the link?
This question already has an answer here:
get child pages of parent ID and display custom image field with link to page in WordPress
(1 answer)
Closed 3 years ago.
I am very new to wordpress and php so excuse me in advance if maybe the answer were already posted, but I looked everwhere and couldnt find a solution to my problem. Or at least I never was able to make work any ideas I tried, and the wordpress documentation is still very complicate for me, when I look through the functions and hook to understand how it is working.
I basically made a slideshow on my home page which display the feature images of the children pages. I have the thumbnails of the images in my side navigation, and the slideshow in my main content section. Basically I am retrieving the ID of each child page by entering the specific id for each slide, but I'd like to make all this dynamic and loop the whole thing, but I don't manage to output the children pages ID dynamically. Here is the hard code I am using now :
<div id="contentContainer">
<div id="wrapper">
<div id="itemOne" class="content">
<?php
$image_id=get_post_thumbnail_id(192);
$image_url=wp_get_attachment_image_src($image_id,'full-size');
echo '<img src="'.$image_url[0].'">';
?>
</div>
<div id="itemTwo" class="content">
<?php
$image_id=get_post_thumbnail_id(196);
$image_url=wp_get_attachment_image_src($image_id,'full-size');
echo '<img src="'.$image_url[0].'">';
?>
</div>
<div id="itemThree" class="content">
<?php
$image_id=get_post_thumbnail_id(198);
$image_url=wp_get_attachment_image_src($image_id,'full-size');
echo '<img src="'.$image_url[0].'">';
?>
</div>
<div id="itemFour" class="content">
<?php
$image_id=get_post_thumbnail_id(200);
$image_url=wp_get_attachment_image_src($image_id,'full-size');
echo '<img src="'.$image_url[0].'">';
?>
</div>
</div>
As I will have more slides than this later on, and in case I need to change the images without going through code, I would like to get this code dynamic, and looping as much slides as it can be.
Thank you for your help!
You can get page id of children by using
get_page_children()
here is an example :-
<?php
// Set up the objects needed
$my_wp_query = new WP_Query();
$all_wp_pages = $my_wp_query->query(array('post_type'=>'page','posts_per_page' => '-1'));
// Get the page as an Object
$parent_page = get_page_by_title('parent_page_title');
// Filter through all pages and find page's children
$page_children = get_page_children( $parent_page->ID, $all_wp_pages );
// echo children page id from $page_children array
foreach($page_children as $children):
echo '<pre>';
print_r($children->ID);
echo '</pre>';
endforeach;
?>
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 :)
EDIT: I've updated this question with the working code, but I've left the content of the text alone so you can see what I was trying to do in the future and also because there were a few other things I wanted to do aside of the initial question.
I have an array that has an html list in it, the php is shuffling the list to echo a random order. Within the list items in the array, I want to include a php variable, right now this is what I have:
<?php include('includes/header_topright_content.php'); ?>
<ul data-options="animation:fade; slide_number:false; pause_on_hover:false; timer_speed:5500; navigation_arrows:false; next_on_click:true; timer:true; bullets:false;" data-orbit>
<?php
$links = array(
'<li data-orbit-slide="headline-1"><img /><div>'.$Slide1.'</div></li>',
'<li data-orbit-slide="headline-2"><img /><div>'.$Slide2.'</div></li>',
'<li data-orbit-slide="headline-3"><img /><div>'.$Slide3.'</div></li>',
);
shuffle($links);
foreach ($links as $link) { echo $link; }
?>
</ul>
I could have up to 10 or even 20 of these slides. The information the variables are linking to would be from a separate .php page that I "included." The information on that page is:
<?php
$Slide1 = "<h5>Slide 1</h5><h6>This is the content for slide 1!</h6>";
$Slide2 = "<h5>Slide 2</h5><h6>This is the content for slide 2!</h6>";
$Slide3 = "<h5>Slide 3</h5><h6>This is the content for slide 3!</h6>";
?>
If I scrap the variable idea and insert the html directly into the list item it works perfectly. If I try to put the variables in there, the slide will just be blank. I'm stuck on where to go from here, I'm great with html and css, but not so good with php, so any help is appreciated! I'm also open to any formatting tips and best practices, the cleaner the better.
Thanks in advance!
MORE INFO: There's a few complications behind as to why I'm looking to do this. The orbit image slider doesn't support a random order, and I found it much easier to just use php to randomize the order of the list items. The reason I want to use variables in these list items is because I'm using a cms (CouchCMS) to make that content editable - a simple solution would be to insert editable tags around that content, but that would only make one page editable, and this content is going to be 'included' in the header of every page. So I'm trying to find a way to put those variables on a separate page (I know 'including' it doesn't do that - maybe I can link it to the page like a css or js file?) to make that editable. If anyone has any ideas for this I'm open!
With string concatenation, your also need to include the variables file before assigning them variables to the array. You also dont need to wrap PHP variables in quotes when echoing.
<?php include('includes/variables.php'); ?>
<ul data-options="[orbit options go here]" data-orbit>
<?php
$links = array(
'<li data-orbit-slide="headline-1"><img /><div>'.$Slide1.'</div></li>',
'<li data-orbit-slide="headline-2"><img /><div>'.$Slide2.'</div></li>',
'<li data-orbit-slide="headline-3"><img /><div>'.$Slide3.'</div></li>',
);
shuffle($links);
foreach ($links as $link) { echo $link; } //<<< notice no quotes
?>
</ul>
Edit:
Can I make a suggestion to your code, by assigning to a slides array directly be it in an external file or not, you will be able to eventually dynamically or easily add new slides to the slider and not need to hard code into a second sub array before the loop. So something like. Also by changing to alternative syntax your keep a nice HTML structure.
<?php
$slide[] = "<h5>Slide 1</h5><h6>This is the content for slide 1!</h6>";
$slide[] = "<h5>Slide 2</h5><h6>This is the content for slide 2!</h6>";
$slide[] = "<h5>Slide 3</h5><h6>This is the content for slide 3!</h6>";
shuffle($slide);
?>
<ul data-options="animation:fade; slide_number:false; pause_on_hover:false; timer_speed:5500; navigation_arrows:false; next_on_click:true; timer:true; bullets:false;" data-orbit>
<?php foreach ($slide as $key=>$value):?>
<li data-orbit-slide="headline-<?php echo $key?>"><img /><div><?php echo $value; ?></div></li>
<?php endforeach;?>
</ul>
I have a WordPress site for a client. He owns a video store, and I made a site for him to update the list of movies, usually just the "new this week" movies.
I used PodCMS as an easy way for him to upload movies and then display them. No need for him to even create posts. Works really well, it's a great extension, I'm just having some issues.
The Pod has a field where you insert the release date. 2010-04-20
Then there is a Pod page/template combo that calls the movies with a certain release date like this:
$date = pods_url_variable('last');
He then just creates a blank WP page with the slug 2010-04-20
So when you open that page, the Pod page/template reads that slug and renders a list of the appropriate movies.
My problem:
I need these to be searchable. Is this possible.
I'm also open to suggestions on other ways to go about making this site work. I need it to be as simple as that. Uploads some movies and creates a new page. Then the rest is done automatically.
A PodsCMS search is nothing more than a mySQL table search for the search term. You can search the title, body, pretty much anything. Here's an example:
Note: I'm using "whatever" as the pod info. I'm also forming a string that goes into the $where position which comprises the various pods variables I want to search on. Also, I'm assuming pagination using the Pods pagination controls but I want that variable carried across the pages so I can offset.
<?php
$search_term = $_GET["s"];
$paged = get_query_var('paged');
$page_number = $_GET['pg'];
?>
<h1>
Results for "<?php echo $search_term; ?>"<?php if($page_number > 1){ ?> (Continued)<?php } ?><?php if($paged > 1){ ?> (Continued)<?php } ?>
</h1>
<?php if($paged <= 1){ ?>
<h2>Results in Whatever...</h2>
<?php
$whateverSentence = "(t.name LIKE '%" .$search_term. "%') || (t.whatever LIKE '%" .$search_term. "%')";
$whatever = new Pod('whatever');
$whatever->findRecords($orderby = 't.whatever DESC', $rows_per_page = 5, $where = $whateverSentence, $sql = null);
$total_whatever = $whatever->getTotalRows();
?>
<?php if( $total_whatever >0 ) : ?>
<?php while ( $whatever->fetchRecord() ) : ?>
<?php
// Set Variables
$whatever_ID = $whatever->get_field('id');
$whatever_Permalink = $whatever->get_field('slug');
$whatever_Name = $whatever->get_field('name');
?>
Code that echos the pods variables and represents the search result
<?php endwhile ?>
<?php else: ?>
<p>Sorry, no results found for that search.</p>
<?php endelse; endif ?>
<?php echo $whatever->getPagination($label = '<span class="pagination-text">Go to page:</span>'); ?>
<?php } ?>
So you need the WordPress page content - the list of movies - to be searchable?
