Ok I have a blog that I've been working on for a couple weeks but I can't figure out how I would insert a tag such as <!--break--> into the blog entry and make it only display up to that <!--break-->. Anyone have any ideas?

I think what your looking for is the substr() function.

PHP Code:

echo substr('$blogpost', 0, 200);  // all the letters between 0 and 200.
echo "..."; 


Good idea Mike, but I think I know of a better way:

PHP Code:

$input = "Some really long <!--break--> bit of text";
$changed = explode("<!--break-->",$input,2);
echo $changed[0];
echo "..."; 


That way you don't need to know the length, just to put in a break where you want it to break.

Hope that helps!

Ah, smart

I guess I did not read the whole post

You could also use a preg. But I think in this case, it does not matter.

I don't think it does.

You way was good of course, if you know how many characters you want; eg in a list or something. It's about horses for courses I guess.

Thanks for the help guys, I actually figured it out shortly after posting this.

Heres the function I made to do it.

PHP Code:

function blogBreak($blogpost) {
    
        // Set the symbol for the break
        $break = '<!--break-->';
        
        // Find where the break is in the blog post
        $position = strpos($blogpost, $break);
        
        // Subtract only up to the break
        $blogshort = substr($blogpost, 0, $position);
    
        return $blogshort;
    
    } 


When I write a blog post in wordpress, I can cut off what I say with a <!--more--> tag, if that's your blogging software.

I'm actually using custom blog software that I created.

If it works, great. I still stick by my method, which is a tad simpler

Good for you for working it out though.
