Hi,
I am trying to create a page, which the used will be able to update herself using Power CMS.
On the index page, I only want to display part of the content, let´s say the first 200 characters, and then to read the remaining content, the user will have to click on "more".
I found a previous entry in this forum, concerning the same issue - your suggestion was to use the following entry:

<?php echo substr(WA_getCMSContent($database_localhost, $localhost,"Home Page", "Welcome"), 0, 150)."..."; ?>

Using my own settings, this should correspond to:
<?php include('cms102/WA_CMS/addtosite.php'); echo substr(WA_getCMSContent($database_localhost, $localhost, 'index.php' , 'content') "), 0, 150)."...";?>

However, when using this, I only get either a blank page, i.e. no content showing at all (not even background color or any design details) or error 500.
What am I doing wrong and how can I get the page to work?

I would actually do it like this:

First add this function at the top of your page:

php:

<?php

// CUTTEXT

function cutText($string, $length) {

if($length<strlen($string)){

while ($string{$length} != " ") {

$length--;
}

return substr($string, 0, $length);

}else return $string;
} 

?>

Then, where your content is:

php:

<?php 

include('cms102/WA_CMS/addtosite.php'); 

$content = (WA_getCMSContent($database_localhost, $localhost, 'index.php' ,  'content');   

$content = strip_tags($content, '<p><a>');

$content = cutText($content, 150);
    
echo $content;

?>

Now, I know this looks like a bit more code, but it will be better in the end because you will use the Strip Tags function to strip out any html tags - such as image tags or other tags that will actually eat up character length. The other problem if you don't strip tags is what happens when your substring ends in the middle of an open html tag such as an image.

In the example I provided, you'll notice after the strip tags command in the parenthesis, I have "<p><a>" as the second attribute. This means that all html tags EXCEPT the p and a tags will get stripped. I usually do this to leave the paragraphs and links in tact while getting rid of images and all other stuff for preview purposes.

After I strip the tags, I then call the custom Cut Text function to trim it down to what I want.

Regards,

Brian

Thanks for your reply! I have tried to do as suggested, but keep getting either a blank page or error 500. What am I doing wrong? I have literally copied the code you sent and pasted it in at the correct (I hope) place - still not working!
I'll be happy to send you the ftp/login details if you want to take a look.
Thanks again.

add the following to line 1 to turn error reporting on:

php:

<?php

error_reporting(E_ALL);

ini_set('display_errors','on');

?>

we will need to know the error that is occurring to have an idea about the cause.

It's impossible to tell what may be wrong without knowing the error message.

Perhaps if you could send a copy of the index3.php page, i could spot something, other than that, you should check with the host to see if they can look into the server error logs to find the error message.

Here is the code:

==========================

<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>
<?php

// CUTTEXT

function cutText($string, $length) {

if($length<strlen($string)){

while ($string{$length} != " ") {

$length--;
}

return substr($string, 0, $length);

}else return $string;
}

?>
