I'm trying to implement a custom functionality to a wordpress shortcode plugin that shows a tooltip for specified words by automatically calling for information from Wikipedia.
Currently my code snippet works fine, but it shows the tooltips for each occurrence of the word in an article. For example if I specified the word : "dessert" in an array it will show the tooltip for all 5 words "dessert" found in the post. I'm looking for a way to limit the tooltip shortcode to be applied only once per word ( in this case "dessert" which has been specified in the array).
Me code snippet is this:
function add_wikitips($content) {
if( is_single() && is_main_query() ) {
$arr = array('dessert');
for ($i = 0; $i < count($arr); $i++) {
$content = str_replace($arr[$i], '[wiki]'.$arr[$i].'[/wiki]', $content);
}
}
return $content;
}
add_filter('the_content', 'add_wikitips');
I tried adding ob_end_clean(); then
static $content = null;
if ($content === null) {
return $content;
}
, but these methods didn't work. Probably because I didn't implement them properly.
Thanks a lot in advance for any advice and suggestions.
Probably, you can try this: Using str_replace so that it only acts on the first match?
You want the first work to have Wiki link. So replace the first occurrence only when you are doing str_replace()
May be like:
function str_replace_first($from, $to, $content)
{
$from = '/'.preg_quote($from, '/').'/';
return preg_replace($from, $to, $content, 1);
}
echo str_replace_first('abc', '123', 'abcdef abcdef abcdef');
// outputs '123def abcdef abcdef'

I have an addition to url e.g. /products/myproduct/?v=iphone-x/transparent/*/Green
So what I need is for wordpress to add the ?v=iphone-x/transparent/*/Green to all links on the page (only '<a href="">'s, no 'img src=""' or others)
I have managed to do that, but it's a little "dirty". Is there any neat function to add the parameter to all links?
The code I have is as follows:
function callback($buffer) {
// modify buffer here, and then return the updated code
$temp = explode('href="', $buffer);
$buffer = $temp[0];
array_shift($temp);
foreach($temp as $t){
$tt = explode('"', $t, 2);
$buffer .= 'href="'.$tt[0].'?v='.$_GET['v'].'"'.$tt[1];
}
return $buffer;
}
function buffer_start() { ob_start("callback"); }
function buffer_end() { ob_end_flush(); }
add_action('wp_head', 'buffer_start');
add_action('wp_footer', 'buffer_end');
One way you can achieve this is to hook into "the_content" filter. By using regexp with preg_replace_callback function you can get decent results.
function add_para( $content ) {
$content = preg_replace_callback(
"/href=(?>'|\")([^\"']+)(?>'|\")/",
function($m) {
print_r($m);
return "href='".$m[1]."/additional-param'";
},
$content);
return $content;
}
add_filter( 'the_content', 'add_para', 0 );
However, you might run into some issues particularly if your content is not formatted probably (extra spaces, missing tags .. etc).
So the alternative is either to us a JS approach (jQuery for example), or using PHP DOM parser like: PHP Simple HTML DOM Parser
I have migrated my contents from a Yii site to Wordpress and I have all my posts filled with div tags with all kind of styles and ids and class and I want to use a pattern to remove them all. I searched the internet and came with this function, yet it does remove the closing tag, but not the opening tags which contains other attributes like style id or class:
function remove_divs($data) {
$filteredContent = preg_replace(array('/<\s*div.*?>/', '</div>'), '', $data['post_content']);
$data['post_content'] = $filteredContent;
return $data;
}
add_filter('wp_insert_post_data', 'remove_divs', 99);
Can you help me figure what isn't working?
Being inspired by the previous answer, I edited my function and it worked just fine. Here is the code:
function remove_divs($data) {
$filteredContent = preg_replace(array('/<\s*div[^>]*>/', '</div>'), '', $data['post_content']);
$data['post_content'] = $filteredContent;
return $data;
}
add_filter('wp_insert_post_data', 'remove_divs', 99);
Thank you for your answer!
You can try this pattern
$pattern = "/<div[^>]*>(.*?)<\/div>/";
$content = '<div class="test">Alpha Beta Gamma</div>Test<div class="best">Delta Gamma Eta</div>';
preg_match_all($pattern, $content, $match);
var_dump($match);
Almost sure that I'm not the first one that has this question but when I test my (WordPress) page on Google Snippet Test Tool I got hatom-enty errors like:
hatom-feed
hatom-entry:
Fout: At least one field must be set for HatomEntry.
Fout: Missing required field "entry-title".
Fout: Missing required field "updated".
Fout: Missing required hCard "author".
I found some tutorials about this but that is for standard WordPress themes. I'm using Inovado from ThemeForest and I can't figure out in which file I have to edit this data.
Someone familiar with this?
I also got problems with snippet review... Good in testresults but doesn't show up in de Google Search Results. Don't know why...
You can Add this code to the function.php file in your theme's directory and it will solve the problems.
//mod content
function hatom_mod_post_content ($content) {
if ( in_the_loop() && !is_page() ) {
$content = '<span class="entry-content">'.$content.'</span>';
}
return $content;
}
add_filter( 'the_content', 'hatom_mod_post_content');
//add hatom data
function add_mod_hatom_data($content) {
$t = get_the_modified_time('F jS, Y');
$author = get_the_author();
$title = get_the_title();
if(is_single()) {
$content .= '<div class="hatom-extra"><span class="entry-title">'.$title.'</span> was last modified: <span class="updated"> '.$t.'</span> by <span class="author vcard"><span class="fn">'.$author.'</span></span></div>';
}
return $content;
}
add_filter('the_content', 'add_mod_hatom_data');
The code contains 2 functions. The first function will use the WordPress filter hook for “the_content” to add the class of “entry-content” to the article. To add in the other essential hAtom fields, the second function will add a short sentence to the end of your post article, which contains updated time, post title and author, with required microdata.
I'm quite new to this (understanding the WP Guts), and I wanted to understand the Hooks and Filters better, I can't get it right from Codex.
I did a simple test,
the idea is to override the get_title() method in order to erase the "Protected: " sentence from the title if the page is protected, there is a protected_title_format filter, and I thought using it ...
that line in post-template.php specifies:
$protected_title_format = apply_filters('protected_title_format', __('Protected: %s'));
for what I could get from CODEX, I need to remove that filter and add my own, like
remove_action('protected_title_format');
apply_filters('protected_title_format', __('MY OWN PAGE Protected: %s'));
using, off course something like
// Removing action
function remove_title_action() {
remove_action('protected_title_format','get_the_title',3);
}
add_action('init','remove_title_action');
// Adding custom function
add_action('protected_title_format','fancy_title', 3, 4);
function fancy_title($id = 0) {
$post = &get_post($id);
$title = $post->post_title;
echo "I'm the king of the world!... >" . $title . "< & >" . $post . "<";
if ( !is_admin() ) {
if ( !empty($post->post_password) ) {
$protected_title_format = apply_filters('protected_title_format', __('MY OWN PAGE Protected: %s'));
$title = sprintf($protected_title_format, $title);
}
}
return apply_filters( 'the_title', $title, $post->ID );
}
I can get the echo to output, but I dont get the $id (and for that, no $title or $post), this method is a copy of get_title() stripping out everything but the protected part string.
Can anyone care to explain me how this works?
Thank you
P.S. I want to learn, this is the idea of this question, not someone to tell me "Hey, just go to post-template.php and change it", because then I would ask "How about when I update WP...?" !
You can actually do this much more simply than what you're trying. You're on the right track though.
Basically, what you want to do is create your own function that will strip out the "Protected: " part of the WordPress titles. The easiest way to do this is to simply create a function that uses preg_replace() to search for the "Protected: " text and strip it. You could just as easily have it auto-replace the string with your own text.
Here's a sample function that does that. We're taking the $title as a parameter and returning the modified version of it.
function remove_protected_text($title) {
$match = '/Protected: /';
$replacement = '';
$title = preg_replace($match, $replacement, $title);
return $title;
}
The next thing we want to do is actually add our function to a filter hook. The filter hook that we're interested in in this cases is 'the_title'. So, we add the following line below the function we just wrote:
add_filter( 'the_title', 'remove_protected_text', 10);
This adds our function remove_protected_text() to the 'the_title' filter. In this case I've used the third argument to give our filter a priority of 10. This is totally optional, but I figure this filter is a pretty low priority.
So all together our code should look like this:
function remove_protected_text($title) {
$match = '/Protected: /';
$replacement = '';
$title = preg_replace($match, $replacement, $title);
return $title;
}
add_filter( 'the_title', 'remove_protected_text', 10);
Adding that code to the functions.php file in your theme will allow it to work. You can write filters like this for most of the parts of WordPress that output text.
Update
Here's a revised version of the function that should get the translated string of "Protected: " and remove it:
function remove_protected_text($title) {
$protected = __('Protected: %s');
$protected = preg_replace('/ %s/', '', $protected);
$match = "/${protected}/";
$replacement = '';
$title = preg_replace($match, $replacement, $title);
return $title;
}
add_filter( 'the_title', 'remove_protected_text');
Basically the only change here is that we are using the __() function to translate the protected string and then striping out the extra bits. This is kind of hackish, and I'm sure there's a better way to do it, but it does work in my testing.
I tested this out on a Spanish version of WordPress and it worked, so let me know if it works for your project.
