Hello list,
I got a problem with displaying content in a "read more block" which
contains HTML code.
The problem is as followes:
I got a large piece of content, which contains HTML code (<b><u><i>
etc), but after 200 characters a read more link appears. At the moment
I strip al the HTML out of this piece of content, and display the full
set off content on another page.
But now i also want to display the bold text etc. in the first (200
chrs) content block. The only problem i have here, is that when I got
a bold tag opend in the first 200 chrs, and it's closed after 400
chrs, then the rest off the page is also bold.
You could try using http://php.net/substr_count and do something like:
$tags = array('<b>', '<i>', '<u>');
foreach ($tags as $p => $tag) {
$count = substr_count($string, $tag);
if ($count % 2 != 0) {
echo "Found a mismatch for tag " . htmlentities($tag) . "<br/>";
}
}
Not a great solution because you're hardcoding the tags you're looking
for but there aren't that many that change text appearances like these
do (but then again this method won't work for <span or <div tags because
you can place styles inside those tags)....
Unless you want to get into regex'es....
Actually that's not going to work at all.
You'd have to do something like:
$open_tags = array('<b>', '<i>', '<u>');
$close_tags = array('</b>', '</i>', '</u>');
foreach ($open_tags as $p => $tag) {
$open_count = substr_count($string, $tag);
$close_count = substr_count($string, $close_tags[$p]);
if ($open_count != $close_count) {
echo "Mismatch for tag " . htmlentities($tag) . "<br/>";
}
}
