我目前正在使用这篇教程中的以下代码,自动将WordPress文章内容拆分成两列。但是,我要如何改变这段代码以输出3列而不仅仅是2列呢?
functions.php 代码:
function content_split($text, $separator = '<hr/>', $start = false ) {
if ( $start === false) {
$start = strlen($text) / 2;
}
$lastSpace = false;
$split = substr($text, 0, $start - 1);
// if the text is split at a good breaking point already.
if (in_array(substr($text, $start - 1, 1), array(' ', '.', '!', '?'))) {
$split .= substr($text, $start, 1);
// Calculate when we should start the split
$trueStart = strlen($split);
// find a good point to break the text.
} else {
$split = substr($split, 0, $start - strlen($separator));
$lastSpace = strrpos($split, ' ');
if ($lastSpace !== false) {
$split = substr($split, 0, $lastSpace);
}
if (in_array(substr($split, -1, 1), array(','))) {
$split = substr($split, 0, -1);
}
// Calculate when we should start the split
$trueStart = strlen($split);
}
//now we know when to split the text
return substr_replace($text, $separator, $trueStart, 0);
}
index.php代码:
<div class="first-column my-column">
<?php $text = get_the_content(); $separator = '</div><div class="second-column my-column">'; echo apply_filters('the_content', content_split($text,$separator)); ?>
</div>
