wordpress are really useful things. here are some hacks that you can use for your wodpress cms development.
Get the fiirst image from the post and display it :
add these codes to your function.php, if you do not have this page, create 1.
function catch_that_image() {
global $post, $posts;
$first_img = '';
ob_start();
ob_end_clean();
$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i',
$post->post_content, $matches);
$first_img = $matches [1] [0];
if(empty($first_img)){ //Defines a default image
$first_img = "/images/default.jpg";
}
return $first_img;
}
global $post, $posts;
$first_img = '';
ob_start();
ob_end_clean();
$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i',
$post->post_content, $matches);
$first_img = $matches [1] [0];
if(empty($first_img)){ //Defines a default image
$first_img = "/images/default.jpg";
}
return $first_img;
}
then you call the function inside the loop:
<?php echo catch_that_image() ?>
however if you want to exclude the image from post here is the code :
<?php
ob_start();
the_content('Read the full post',true);
$postOutput = preg_replace('/<img[^>]+./','', ob_get_contents());
ob_end_clean();
echo $postOutput;
?>
ob_start();
the_content('Read the full post',true);
$postOutput = preg_replace('/<img[^>]+./','', ob_get_contents());
ob_end_clean();
echo $postOutput;
?>
If you want to use customer field for your posts is pretty easy too :
add these code to your function:
function get_custom_field_value($szKey, $bPrint = false) {
global $post;
$szValue = get_post_meta($post->ID, $szKey, true);
if ( $bPrint == false ) return $szValue; else echo $szValue;
}
global $post;
$szValue = get_post_meta($post->ID, $szKey, true);
if ( $bPrint == false ) return $szValue; else echo $szValue;
}
then you call your customer field:
<?php if ( function_exists('get_custom_field_value') ){
get_custom_field_value('featured_image', true);
} ?>
get_custom_field_value('featured_image', true);
} ?>
