Send email through wp_mail in html format with wordpress

We can use this code for contact form or in functions.php file

For html format email from wordpress. we just need to add following line in functions.php file.

add_filter('wp_mail_content_type',create_function('', 'return "text/html";'));

Sending HTML email has risks. It could be caught in spam filters. The client may not support HTML formatting (although that’s rare). The client may disable email HTML from using javascript, CSS or grabbing remote assets like images.

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.

<?php
require('/the/path/to/your/wp-blog-header.php');
?>

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:

<?php
require('/the/path/to/your/wp-blog-header.php');
?>

<?php
$posts = get_posts('numberposts=10&order=ASC&orderby=post_title');
foreach ($posts as $post) : start_wp(); ?>
<?php the_date(); echo "<br />"; ?>
<?php the_title(); ?>
<?php the_excerpt(); ?>
<?php
endforeach;
?>

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)

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 then 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 then 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.

1. 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)
2. 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 /<unix path to the directory where php.ini is>/
(keep the slashes)
4. Edit wp-config.php and enter the following line
define('WP_MEMORY_LIMIT', '64M');
5. Upload the new files to the server

Oh, and don't tell your hosting provider you've done this...

This will solve your issue.

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

Just use the following code in your template or theme file.

<?php get_header(); ?>

            <?php  query_posts( 'post_type=custom-post-type&paged='.$paged );
                                    if (have_posts()) : while (have_posts()) : the_post(); ?>

loop here

              			<?php endwhile; ?>
				  <div id="nav-below" class="navigation">
					<div class="nav-previous"><?php next_posts_link( __( '<span class="meta-nav">&larr;</span> Older posts', 'twentyten' ) ); ?></div>

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');
