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.

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.

For showing the custom post type we always use the query_post method.

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');
