— A couple of months ago I got requested to deliver a website that would let the client publish online brochures. These brochures featured image slideshows with a description text, tags, categories etc. Many of us use WordPress not only as a blog platform but also as a multifaceted CMS. There are many features WordPress give that go beyond the blog format and that with the right adjustments and/or plugins, can be used to provide a complete solid solution. Thats why we choose to build this up on WordPress.
At first I look around to see the wp plugins available but found that none of them suited the needs of this project. I wanted to keep this very simple and easy for the client, so the best solution I came up was to let client dump any image he wanted in the post’s content-box and deal with it later with regular expressions. This way I could manage the content and present it in a good looking slideshow I could style myself.
It didn’t took much time to do it once I figured out what I wanted it to do as it’s simple PHP code:
// Start the Loop
<?php if (have_posts()) : ?><?php while (have_posts()) : the_post(); ?>
<?php
// Set the post content to a variable
$szPostContent = $post->post_content;
// Define the pattern to search
$szSearchPattern = '~<img [^\>]*\ />~';
// Run preg_match_all to grab all the images and save the results in $aPics
preg_match_all( $szSearchPattern, $szPostContent, $aPics );
// Count the results
$iNumberOfPics = count($aPics[0]);
// Check to see if we have at least 1 image
if ( $iNumberOfPics > 0 )
{
// Now here you would do whatever you need to do with the images
// For this example I'm just going to echo them
for ( $i=0; $i < $iNumberOfPics ; $i++ )
{
echo $aPics[0][$i];
};
};
// ...finish the loop, etc
