How to add a "Read more" button to my blog? - php

Question

I have an HTML template which I convert to a Wordpress theme, but i can't add a "Read more" button to the home page.
I use the following code in functions.php:
function the_content_limit($max_char, $more_link_text = '(more...)', $stripteaser = 0, $more_file = '') {
$content = get_the_content($more_link_text, $stripteaser, $more_file);
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]>', $content);
$content = strip_tags($content);
if (strlen($_GET['p']) > 0) {
echo "<p>";
echo $content;
echo "</p>";
}
else if ((strlen($content)>$max_char) && ($espacio = strpos($content, " ", $max_char ))) {
$content = substr($content, 0, $espacio);
$content = $content;
echo "<p>";
echo $content;
echo "...";
echo "</p>";
}
else {
echo "<p>";
echo $content;
echo "</p>";
}
}
I also use the following code in index.php:
<div class="text_home"><?php the_content_limit(300); ?></div>
What can I do to solve my problem?

Answer 1

//keep this code in function.php
function get_excerpt($limit=10, $content) {
$content = explode(' ', $content,$limit);
if (count($content)>=$limit) {
array_pop($content);
$content = implode(" ",$content);
$content = $content.' ...';
} else {
$content = implode(" ",$content);
}
return $content;
}
where you want to call this function
$content = get_the_content();
$content = strip_tags($content);
echo get_excerpt(15, $content);
