WordPress Conditional PHP Question - php

I'm trying to call WordPress's 'the_time' using a conditional statement that checks the category. I want to call the custom field 'event_date' if the category is '3' and 'the_time()' if the category is '4'... This is what I have, and it echoes fine if I use "is_single()" instead of "is_category()" but for some I'm getting no echo when I use "is_category()"... any ideas?
<?php
if (is_category('4')) {
echo "<span>";
the_time('');
echo "</span>";
} elseif (is_category('3')) {
echo "<span>";
get_post_meta ('event_date');
echo "</span>";
} else {
echo "<p>Pedro offers you his protection.</p>";
} ?>

In this instance you want to use in_category instead of is_category.

Show url only if value is present

Goal:
Instead of showing simple YES or NO.
If value is found in record, show hyperlink with that value or else show text "No"
How to modify below code for this purpose:
<?php echo $row_RecordsetContacts['propertyFile'] ? '<strong>Yes</strong></br>' : 'No</br>'; ?>
View
</td>
<?php
$file = $row_RecordsetContacts['propertyFile']; # for readability only
if ($file)
{
?>View<?php
}
else
{
?>No<?php
}
I also suggest to avoid mixing echo and HTML markup. In 99% cases it makes the code better for understanding.
Try the following code:
<?php
$prop = $row_RecordsetContacts['propertyFile'];
if(empty($prop)) {
echo "No";
} else {
echo "<a href='propfiles/$prop'>View</a>";
}
?>

How to add php string that get category title in wordpress

I just wanted to know how to apply php string when you want to get the title:
ex.
<h1 class="page-title"><?php single_cat_title(__('category:','themename')); ?></h1>
so if the title is "Video's", the button in the content will change to "Watch now" instead of "Read more" which is the default.
something like
if title is = "video's" {
echo "<button>Watch now</button>"
}<button>Readmore</button>
You need false as second parameter to just return the value (not print). And then just compare it.
if (single_cat_title("", false) == "video's") {
echo "Watch now";
} else {
echo "Read more";
}
Simple PHP if/else
Here's the code which will work for you
if (single_cat_title("",false) == "video's") {
echo "<button>Watch now</button>"
} else {
echo "<button>Readmore</button>"
}
I am just assuming that title is actually titled video
Here is basic approach you can check video post by it's category id even with the category name. here is the example code.
$category_id = get_cat_ID('Category Name');
if( $category_id == 'your cat id'){
echo 'watch video';
{
else{
echo 'readmore';
}
Hope it helps. cheers!

Wordpress if condition is or has_tag

I'm trying to make an if condition if there's a tag then echo it if not just show the archive title.
$title_before = '<h1 class="archive_header">';
$title_after = '</h1>';
if(is_tag('tag_description')){
echo '<div class="archive_desc">';
echo tag_description();
echo '</div>';
echo '<div class="archive_border"></div>';
} else {
woo_archive_title( $title_before, $title_after );
}
I tried the code above and the tag description is not showing, though I'm not entirely sure if is_tag covers tag_description.
The is_tag function checks if a tag archive page is being displayed.
Is that what you want?
Found my way now, I wanted !empty. So if there is no tag/archive description it only shows the title, then if exist it shows both.
$tag_description = tag_description();
woo_archive_title( $title_before, $title_after );
if(!empty($tag_description)){
echo '<div class="archive_desc">' .$tag_description. '</div>';
echo '<div class="archive_border"></div>';
} else {
//
}
Now I need to do the styling.

WordPress breadcrumbs in search results

In WordPress i'm currently using Yoast's SEO Plugin to display breadcrumbs for my pages and posts, which is working fine when visiting a specific page.
Here is the function i'm using to display the breadcrumbs inside of my WordPress templates:
<?php if ( function_exists('yoast_breadcrumb') ) {
yoast_breadcrumb('<p id="breadcrumbs">','</p>');
} ?>
For example when browsing to Team Members which is a child of About Us I get:
Home > About Us > Team Members
However i'd like to be able to display the same breadcrumbs (for the individual pages and posts) inside the search results loop.
So far what displays when searching for Members is:
Your Search Results:
Team Members
Home > Search > Members
Members Area
Home > Search > Members
But I don't want breadcrumbs for the Search Results page, I want them for the individual pages and posts that are displayed as a result of searching for a keyword.
For example Imagine I searched again for Members I would like displayed the below:
Your Search Results:
Team Members
Home > About Us > Team Members
Members Area
Home > Members Area
I'm not fussed if this is or isn't integrated with the SEO plugin, however thus far it's the best solution I found to display breadcrumbs in WordPress!
Also incase abody requires it, here is my search.php file: http://pastebin.com/0qjb2954
Try this. That's my own working snippet that shows breadcrumbs inside search loop.
/*Begin Loop */
<?php
echo '<div class="b-search_result_list__item_breadcrumbs breadcrumbs">';
$current_type = get_post_type();
if ($current_type == 'page') {
$parents = get_post_ancestors(get_the_ID());
if($parents){
for($i=count($parents)-1;$i>=0;$i--){
echo '<span typeof="v:Breadcrumb">';
echo '<a rel="v:url" property="v:title" title="'.get_the_title($parents[$i]).'" href="'.get_permalink($parents[$i]).'">'.get_the_title($parents[$i]).'</a>';
echo '</span>';
}
}else{
echo '<span typeof="v:Breadcrumb">';
echo '<a rel="v:url" property="v:title" title="'.get_bloginfo('name').'" href="'.get_bloginfo('url').'">'.get_bloginfo('name').'</a>';
echo '</span>';
}
echo '<span typeof="v:Breadcrumb">';
echo '<span property="v:title">'.get_the_title().'</span>';
echo '</span>';
}else{
$current_obj = get_post_type_object($current_type);
echo '<span typeof="v:Breadcrumb">';
echo '<a rel="v:url" property="v:title" title="'.get_bloginfo('name').'" href="'.get_bloginfo('url').'">'.get_bloginfo('name').'</a>';
echo '</span>';
echo '<span typeof="v:Breadcrumb">';
echo '<a rel="v:url" property="v:title" title="'.$current_obj->labels->name.'" href="'.get_post_type_archive_link( $current_type ).'">'.$current_obj->labels->name.'</a>';
echo '</span>';
$current_taxonomies = get_object_taxonomies($current_type);
if($current_taxonomies){
$current_terms = get_the_terms(get_the_ID(), $current_taxonomies[0]);
if($current_terms){
$current_term = array_shift($current_terms);
echo '<span typeof="v:Breadcrumb">';
echo '<a rel="v:url" property="v:title" title="'.$current_term->name.'" href="'.get_term_link($current_term).'">'.$current_term->name.'</a>';
echo '</span>';
/*
var_dump($current_obj->labels->name); // Archive name
var_dump(get_post_type_archive_link( $current_type )); // Archive link
var_dump($current_term->name); // Term name
var_dump(get_term_link($current_term)); // Term link
var_dump(get_permalink()); // Post link
*/
}
}
echo '<span typeof="v:Breadcrumb">';
echo '<span property="v:title">'.get_the_title().'</span>';
echo '</span>';
}
echo '</div>';
?>
/*End Loop*/
try adding this line of code above the yoast breadcrumb function in your search.php file:
WPSEO_Breadcrumbs::$instance = NULL;
This would be line 22 I believe, and also make sure to use the Yoast breadcrumb function from your question, not the new breadcrumb() function that's there now.
Please let me know if this works!
Full explanation:
The Yoast plugin breadcrumbs functionality is build on the page load, based on the current page as the child. To make it load the right child and parents, you'd need to reset it before you run the function. There is no built-in reset function, however setting the static $instance to NULL should cause the plugin to re-generate its data based on the current global post object which is set while you're looping.
Building upon Yavor's answer I found a way. Been banging my head about it for hours. You can place the backup and restore otuside of the loop though. Here it is:
global $wp_query;
//backup
$old_singular_value = $wp_query->is_singular;
//change
$wp_query->is_singular = true;
//reset
WPSEO_Breadcrumbs::$instance = NULL;
//breadcrumbs
if (function_exists('yoast_breadcrumb')){
yoast_breadcrumb('<p id="breadcrumbs">','</p>');
}
//restore
$wp_query->is_singular = $old_singular_value;
It fakes the query to make it singular so the newly-refreshed breadcrumbs thinks that this is not the search page but a single post or page or whatever you are displaying as your search results.
Using a plugin to generate breadcrumbs is not really necessary. Here's a simple PHP function you can add to your functions.php file:
function breadcrumbs() {
global $post;
echo "<ul id='breadcrumbs'>";
if (!is_home()) {
echo '<li>Home</li>';
if (is_category() || is_single()) {
echo "<li>" . the_category(' </li><li> ');
if (is_single()) {
echo "</li><li>" . the_title() . "</li>";
}
} elseif (is_page()) {
if($post->post_parent){
foreach ( get_post_ancestors( $post->ID ) as $ancestor ) {
echo '<li>' . get_the_title($ancestor) . '</li>' . get_the_title();
}
} else {
echo "<li>" . get_the_title() . "</li>";
}
}
} elseif (is_tag()) {
single_tag_title();
} elseif (is_day()) {
echo "<li>Archive for " . the_time('F jS, Y') . "</li>";
} elseif (is_month()) {
echo "<li>Archive for " . the_time('F, Y') . "</li>";
} elseif (is_year()) {
echo "<li>Archive for " . the_time('Y') . "</li>";
} elseif (is_author()) {
echo "<li>Author Archive</li>";
} elseif (isset($_GET['paged']) && !empty($_GET['paged'])) {
echo "<li>Blog Archives</li>";
} elseif (is_search()) {
echo "<li>Search Results for" . the_search_query() . "</li>";
}
echo "</ul>";
}
along with some CSS to style it, customize as you desire
#breadcrumbs {
list-style:none;
margin:5px 0;
overflow:hidden;
}
#breadcrumbs li{
float:left;
}
#breadcrumbs li+li:before {
content: '| ';
padding:0 4px;
}
You can then implement those breadcrumbs on any page you like, including your searchpage.php file or whichever file you use to display search results with this call
<?php breadcrumbs(); ?>
The search pages have a conditional function that can be used. You could always apply that to loading the breadcrumbs. Here is an example:
if ( ! is_search() ) {
if ( function_exists('yoast_breadcrumb') ) {
yoast_breadcrumb('<p id="breadcrumbs">','</p>');
}
}
It depends where you are loading the breadcrumbs as well, but this should typically work unless your theme is very unique.

how to check if foreach loop empty when using json and php

i'm using JSON to get data and then PHP to display. so...
i'm showing everything available to a person and i want to echo a message when the loop is blank/empty that "there's nothing available" because right now it just shows a blank screen when there is no data... any ideas??
<?
foreach($json['available'] as $r) {
echo '<li>' .$r['item'].'</li>';
}}
?>
Just use an if statement and check if $json['available'] is empty with empty().
if( empty( $json['available'])) {
echo '<li>No items are available</li>';
} else {
foreach($json['available'] as $r) {
echo '<li>' .$r['item'].'</li>';
}
}
Use empty to check if $json contains something or not.
Assuming that $json['available'] is going to be an empty array at worst:
if (!$json['available']) {
echo "nothing to show!";
}
else {
// your current code
}
If it's possible that $json['available'] might not even exist, a more "heavy-handed" alternative is
if (empty($json['available'])) {
echo "nothing to show!";
}
