I have an array of user ids and I need to go through the a user: id field within a view, adding a bit of specific HTML for matching and non-matching results.
So I'm guessing something like this needs to go in views-view-field--uid.tpl.php:
<?php if (//Field content matches an array value): ?>
<span class="friend"><?php print $output; ?></span>
<?php endif; ?>
<?php if (//Field content doesn't match an array value): ?>
<span class="not-friend"><?php print $output; ?></span>
<?php endif; ?>
Can someone help me fill in the gaps, please? :)
Assuming $ouput is going to be only an integer representing the uid (and not HTML markup), you could do something like this:
<span class="<?php if(!in_array($output, $your_array)): ?>not-<?php endif; ?>friend">
<?php print $output; ?>
</span>
see php in_array()
However, $output might be HTML. If that's the case you should use $row instead of $output.
To see what $row contains I love doing this in template files:
<!-- <?php echo print_r($row,true); ?> -->
(then view source in browser)
Also, I'd recommend not doing this at all in your template file because it ties logic to the theme... Check out Views Customfield -- it will let you do PHP in a custom field... If you put it under the UID, and exclude UID from display, you can access the UID and execute the same code I've got above in the custom field, using the $data object instead of $row or $output.

Is it possible to only show the code below if there's a category description?
<h2>About <?php $cat = get_the_category(); echo $cat[0]->cat_name; ?></h2>
<?php $catID = get_the_category(); echo category_description ( $catID[0] ); ?>
I have these codes on my single posts in Wordpress but sometimes, I forgot to add descriptions on a new category that I added. So when a user visits the post, they will just see the word About Category and no description at all, making it looks like an incomplete article.
I'm not a developer and I'm also not familiar with PHP. I only added that code on the single.php to show the description. But I want it not to show when there's no description available.
Hope someone can give me the exact code to make it work.
Thanks!
Good practice to assign your values into variables at the top of your script before entering into HTML whenever possible. This will help prevent you making redundant calls and to debug your code better. Once you have your assigned values, you'll want to check if the value is empty. I am assuming the code you presented will always return some kind of value for index 0.
<?php
$cat = get_the_category();
$cat_0 = $cat[0];
$cat_0_name = $cat_0->cat_name;
$cat_0_desc = category_description($cat_0);
?>
<?php if(!empty($cat_0_desc)): ?>
<h2>About <?php echo $cat_0_name; ?></h2>
<?php echo $cat_0_desc; ?>
<?php endif; ?>
I should like to point out that I am choosing to use an alternative syntax for control structures versus the traditional brace control. This will make your code more readable and easily debugged when mixed in with HTML.
If your code is still throwing you errors, I would suggest you check your error logs as something would be happining during the get_the_cateory() call or that it's not returning any values resulting in error with $cat[0].
<?php if ($cat = get_the_category() && count($cat)>0) { ?>
<!-- <?php echo print_r($cat,1); ?> -->
<h2>About <?php echo $cat[0]->cat_name;?></h2>
<?php echo category_description ($cat[0]->cat_id); ?>
<?php } ?>
The Mysql command is set correctly, since the data is displayed correctly via print_r($ads). I pack the resulting array into $ads
Catch id
$id = htmlentities($_GET['id']);
Query DB.
SELECT
rent.id,
rent.run,
rent.year,
FROM rent
WHERE rent.id = '.$id.'
ORDER BY rent.time_upload DESC');
But through the isset function, they are not shown, no errors are displayed, nothing, just a blank page.
I output the data like this
<?php if (isset($ads)): ?>
<h3>
<?=$ads['id'];?>
<?=$ads['run'];?>
<?=$ads['year'];?>
</h3>
<?php endif; ?>
short_tags are included in PHP.
Please help solve the problem.
You're not going deep enough. $ads['run'] doesn't exist, only $ads['3625']['run'] does. Try:
<?php
foreach( $ads as $ad ) {
?>
<h3>
<?=$ad['id'];?>
<?=$ad['run'];?>
<?=$ad['year'];?>
</h3>
<?php
}
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 my data being output to a span currently... this is how it looks:
Now, when i remove the span and place a div there i am given this output:
This is desired, but I want to set a height to my page and have the data show up in as little as 3 columns. How would I do this? I have searched everywhere online but can't seem to find anything that shows a solution.
I did read that some use javascript for the format but i am still clueless on even this option.
My desired output would look like this:
If you know how many items you want in a column then you can seperate them out into individual divs and then float those divs to the left to get them to be next to each other.
<div style='float:left'>
//Items go here
</div>
<div style='float:left'>
//Items go here
</div>
etc.
If you figure out how many items your query returned, say using mysql_num_rows() and divide by 3 you can tell how many to put in each column.
Also be sure to clear the floats afterwards, so like this:
<div style="clear:both"></div>
Sometimes this is necessary as there will be random issues if this is not put there.
What you are describing can be solved with styling only. You have several divs that must be displayed in columns. The easiest way is floating them to the left, and setting the width for 1/3 of the parent. If you want 4 columns, set the with to 1/4 of the parent, and so on.
<div class='sqlResult' style="float:left;width:33%;">
<a href='#'>$key</a>
</div>
Also as other answers mentioned, don't use duplicated ids. Always use classes. If you need to target each div individually, give it a unique id, such as "category_1", "category_2", and so on.
This should work
<table><tr>
<?php $count=0; $total=mysqli_stmt_num_rows($sql)-1; $idxcount=0; $limit=10; while($row = mysqli_fetch_array($sql)): $key = $row['Keyword_Name']; ?>
<?php if($count == 0){ echo '<td>';} ?>
<span>
<?php echo $key; ?>
</span>
<?php if($total == $idxcount): ?>
</td>
<?php elseif($count == $limit): ?>
</td>
<?php $count=0; else: $count++; ?>
<?php endif; $idxcount++; ?>
<?php endwhile; ?>
</tr></table>
I'm using Views 3 in Drupal 7 to output a list of fields and using a grouping field to generate separate lists. I need each of the groupings to have a unique ID attribute applied to the < ul > but they don't by default.
As far as I'm aware I would need to edit the views-view-list.tpl.php template but I don't know how to achieve a unique ID per iteration.
Can anyone help please?
easiest way I can think of off the top of my head...
<?php print $wrapper_prefix; ?>
<?php if (!empty($title)) : ?>
<h3><?php print $title; ?></h3>
<?php endif; ?>
<ul id="<?php echo uniqid(); ?>">
<?php foreach ($rows as $id => $row): ?>
<li class="<?php print $classes_array[$id]; ?>"><?php print $row; ?></li>
<?php endforeach; ?>
</ul>
<?php print $wrapper_suffix; ?>
that would go in your views-view-list.tpl.php file.
For future reference:
Put a div around everyting in view-views-list.tpl.php. You can (ab-)use the $title to generate unique (but consistent) id's.
Do it like this:
<?php $id = str_replace('FOR ALL UNWANTED CHARS','',$title); ?>
<div id="<?php print strtolower($id); ?>">
You can use the $view->dom_id variable. It is a unique id for that views instance.
In your .tpl.php file:
<?php print $view->dom_id; ?>
From comments in modules\views\theme\theme.inc:
<?php
// It is true that the DIV wrapper has classes denoting the name of the view
// and its display ID, but this is not enough to unequivocally match a view
// with its HTML, because one view may appear several times on the page. So
// we set up a hash with the current time, $dom_id, to issue a "unique" identifier for
// each view. This identifier is written to both Drupal.settings and the DIV
// wrapper.
