Readmore

How would I make a read more to a news post? Right now it echos everything in the news_message table.

I'd probably just show the first few words of a given article, which could be achieved by exploding by a space, and echoing the first few words. For example:

<?php
$str = 'Here is my news arcticle that i only want to show the first few words of';
$num_words = 3;
$words = explode(' ',$str);
$i = 0;
$teaser = '';
while($i<$num_words){
$teaser .=' '.$words[$i];
$i++;
}
echo $teaser;
?>

 

You'd then include a link after that to read the whole article.

that is a nasty idea to explode that big string, instead way better idea is find the first  punctuation mark that falls greater than X characters in (like 10ish).  Then just echo out a cut string from 0-that mark, unless that mark is greater than Y characters (say y is 25ish) then it just shows the first Y characters. By exploding you going to make a lot of useless data.  Exploding this post alone is like a 50 item array, vs a test for that comma, and then simply displaying that portion up to it.

Indeed. But what happens when you get people who dont use punctuation?

 

Edit: Whoops. Didn't read your post properly. Perhaps that would be a better solution.

is there anyway I can make it so it only allows like 100 letters?

[darkfreaks]

if($str>100) { echo "there are too many words"; }

Um, darkfreaks $str would have to be an integer for that to be true.

 

strlen() would do what darkfreaks is showing.

 

<?php
$string = "i like to spam chats and have fun while randomly typing sentences using only my pointer fingers can this sentence have any more run ons?";

if(strlen($string) > 100){
$dot = " ...";
}else {
$dot = "";
}

echo substr($string,0,100) . $dot;
?>

 

Will show:

 

i like to spam chats and have fun while randomly typing sentences using only my pointer fingers can ...

[darkfreaks]

oh i see i forgot to check the length first thanks mc 

[unidox]

so for the $string I would put the news_message like

 

$string = $mysql[news_message];

 

?

[marcus]

Correct.
