WordPress tutorial, Show comments from custom post type in wordpress. we shows comments in sidebar. But what to do for show comments for custom post type.
Show comments from custom post type in wordpress
It’s not well documented, but according to the codex, you can pass a ‘post_type’ variable in the get_comments function.
<?php
$comments = get_comments('number=10&status=approve&post_type=YOUR_POST_TYPE');
foreach($comments as $comment) :
// comment loop code will go here

WordPress tutorial, Change image name to wordpress post slug during upload. If you want to rename files during upload and set their names to the post slug.
If you want to rename files during upload and set their names to the post slug the files are being attached to, plus some random characters (a simple incremental counter will be just fine) to make the filenames different.

Change image name to wordpress post slug during upload
In other words, if you are uploading/attaching images to the post whose page slug is “test-page-slug”, i’d like for the images to be renamed on the fly to test-page-slug-[C].[original_extension] — test-page-slug-1.jpg, test-page-slug-2.jpg etc (no matter what the original filenames were).
This is very easy. You just need to use following hook in functions.php file.
function wp_modify_uploaded_file_names($image_name) {
// Get the parent post ID, if there is one
if( isset($_GET['post_id']) ) {
$post_id = $_GET['post_id'];
} elseif( isset($_POST['post_id']) ) {
$post_id = $_POST['post_id'];
}
// Only do this if we got the post ID--otherwise they're probably in
// the media section rather than uploading an image from a post.
if(is_numeric($post_id)) {
// Get the post slug
$post_obj = get_post($post_id);
$post_slug = $post_obj->post_name;
// If we found a slug
if($post_slug) {
$random_number = rand(10000,99999);
$image_name['name'] = $post_slug . '-' . $random_number . '.jpg';
}
}
return $image_name;
}
add_filter('wp_handle_upload_prefilter', 'wp_modify_uploaded_file_names', 1, 1);
This is very easy.
if you have pretty permalinks enabled, so I’ve added a check to make sure there is a slug before renaming the file. You’ll also want to consider checking the file type, which I haven’t done here–I’ve just assumed it’s a jpg.
We just saw the issue with qtranslate slug with widget is not working for 0.5 version. URL is showing but URL is not opening and 404 page is opening. we solved the of qTranslate slug with Widget not working with pages.
Solved issue qTranslate slug with Widget not working with pages
The problem was exactly at the function qTranslateSlug_filter_request inside de file qtranslate-slug-with-widget.php, which is the only one of the plugin, so it’s easy to find.
We must take a look at this part of the code:
Solved: qTranslate slug with Widget not working with pages
With the last wordpress versions, mine is 3.3.1, has changed the way of passing the query to the request filter, changing the array slug position from ‘pagename’ to ‘name’, then the plugin didn’t have a way to find any page, since it expected to find in the array the position ‘pagename’, nonexistent for the current case.

WordPress is very easy to work on. PHP tutorial, how to integrate wordpress into php website. you can very easily integrate the wordpress with php or html site. Here we given code for same.
There may be only a few features of WordPress you want to use when integrating it with your site, or you may want your entire site run with WordPress. This tutorial will guide you through making your WordPress site look like your current design.
how to integrate wordpress into php website
How to start?
First you need to disable the wordpress theme. using following code.
open your header.php file from your wordpress theme and put following code in that file.
<?php
/* Short and sweet */
define('WP_USE_THEMES', false);
require('./wp-blog-header.php');
?>
Create any php file and put following code in that file.
In the event you want to show ten posts sorted alphabetically in ascending order on your web page, you could do the following to grab the posted date, title and excerpt:
Many times we use the custom post type in wordpress. Wordpres tutorial, In wordpress add tags and categories to custom post type. Some times we need to category and tags for custom post type which associated.
In wordpress add tags and categories to custom post type
you can use the following code in functions.php file.
We solved Allowed memory size of 33554432 bytes exhausted which for wordpress. Given solution for allowed memory. Change given for wordpress/wp-config.php file.
Solved Allowed memory size of 33554432 bytes exhausted
We got always following ERROR PHP Fatal error:
Allowed memory size of 33554432 bytes exhausted (tried to allocate 10485761 bytes)
This issue with old and new wordpress versions both. First you need to increase memory limit for your php package. Use following method for increase the memory for php.
Open php configuration file
# vim /etc/php.ini
Change following sections:
max_execution_time = 300 ; Maximum execution time of each script, in seconds
max_input_time = 300 ; Maximum amount of time each script may spend parsing request data
memory_limit = 128M ; Maximum amount of memory a script may consume (16MB)
After this dont forget to restart apache server.
I know on 2.5.1 i needed to increase the memdory, but i don’t know how in 2.6. in the wp-config.php there no define to increase memory. If you are using old wordpress version less than wordpress 2.6 version or you are using the wordpress MU then use following code. open your wp-settings.php file from root folder and change following line
if ( !defined('WP_MEMORY_LIMIT') )
define('WP_MEMORY_LIMIT', '32M');
to
if ( !defined('WP_MEMORY_LIMIT') )
define('WP_MEMORY_LIMIT', '128M');
If you are using the newer wordpress version greater than 2.7 then use following method. Following URL is also helpful http://codex.wordpress.org/Editing_wp-config.php
#Increasing_memory_allocated_to_PHP Edit wp-config.php and enter the following line
define('WP_MEMORY_LIMIT', '64M');
If you are using the shared hosting then use following method.
Create a file called php.ini in the root of your site (if you are using a hosted addon domain, this must be in the subdirectory of that site)
In php.ini, enter a line that says memory_limit = 64MB 3. In your site’s .htaccess (being a WordPress blog, I’m assuming there is one), enter the following line SetEnv PHPRC // (keep the slashes)
Edit wp-config.php and enter the following line
define('WP_MEMORY_LIMIT', '64M');
Upload the new files to the server Oh, and don’t tell your hosting provider you’ve done this… This will solve your issue.
Solved Allowed memory size of 33554432 bytes exhausted
From wordpress 3.0 version, wordpress started the custom post type functionality. There are API provided by wordpress for adding the pagination for custom post type. Some WP developers asked me about pagination of custom post type. That is very easy to add the pagination. Here in this article I given the code snippet for showing the pagination in custom post type.
solved wordpress custom post type pagination not working
For showing the custom post type we always use the query_post method.
Just use the following code in your template or theme file.
I struggled lot for this issue. Some times I only removed the first image. some times I removed first caption. Using following code you can easily remove the post first image and caption.
How to remove first image from wordpress post with caption if caption is present
I used the following code for first image removing.
/*
* Removing the first image from post
*/
function remove_first_image ($content) {
if (!is_page() && !is_feed() && !is_feed() && !is_home()) {
if (preg_match("/<img[^>]+\>/i",$content)) {
$content = preg_replace("/<img[^>]+\>/i", "", $content, 1);
}
return $content;
}
}
But I faced the some issues with that code. When first image has caption then only image get removed and caption will remain there.
After that I used the following code for caption remove.
/*
* Removing the first caption from post with image
*/
function remove_first_image_caption ($content) {
if (!is_page() && !is_feed() && !is_feed() && !is_home()) {
$content = preg_replace("(\)", "", $content, 1);
} return $content;
}
add_filter('the_content', 'remove_first_image_caption');
But if first image has no caption and second image image has caption then both the images will be get removed from post.
After some struggle I written following code. Following is the solution:
Final Code.
/*
* Removing the first image from post
* functionality added to delete caption is present to first image.
*/
function remove_first_image ($content) {
if (!is_page() && !is_feed() && !is_feed() && !is_home()) {
if (preg_match("/<img[^>]+\>/i",$content)) {
//find first image URL
$first_img = '';
$output = preg_match_all('/< *img[^>]*src *= *["\']?([^"\']*)/', $content, $matches);
$first_img = $matches[1][0];
//find first image caption inner text
$output = preg_match_all("/caption=['"](.*)/", $content, $matches);
//find first image present in first caption text or not
$pos = strpos($matches[0][0], $first_img);
// if image URL found in caption array then delete the caption and image
if ($pos !== false) {
$content = preg_replace("(\)", "", $content, 1);
} else {
$content = preg_replace("/<img[^>]+\>/i", "", $content, 1);
}
}
} return $content;
}
add_filter('the_content', 'remove_first_image');
solved: pagination for Custom post type not working
Some people asked me about pagination of custom post type. That is very easy.
For showing the custom post type we always use the query_post method.
Just use the following code in your template or theme file.
