conclusion of the article

[Андрей]

the entire article is 300 characters in a certain field, you must first display 100 characters and a link to more details when clicked, to fully show the full article as to limit the number of characters

 thank you

[kongondo]

Actually, Andrew, I have just realised the above may not be what you want. The above limits how many characters you can type. If on the other hand, you are looking for something that will trim the amount of text entered to a certain number, there was some code posted here on the forums but can't find it at the moment...

Here it is, by Ryan

<?php
// make our own summary from the beginning of the body copy
// grab the first 255 characters
$summary = substr($story->body, 0, 255);

// truncate it to the last period if possible
if(($pos = strrpos($summary, ".")) !== false) {
    $summary = substr($summary, 0, $pos);
}

where to insert the code Ryan, below is my code that I use to display the

<div id="main"><?php echo $page->main; ?>

            

                     <?php foreach($pages->get("/sections/")->children as $child) : ?>

    <div class="one_third first column_container">

    <div class="portfolio-image-holder">

    <div class="portfolio-image">

            <a href='<?php echo $child->url; ?>'>

                <img src='<?php echo $child->images->first()->url; ?>'>

            </a>

        </div>

    </div>

    <?php  

    echo "<h1><a href='{$child->url}'>{$child->title}</a></h1>";

    echo "<p>{$child->text}</p>";     //  displaying text in the field

    ?>   

  </div>

<?php endforeach; ?>     

                </div>

does not work

Error: Call to a member function first() on a non-object (line 50 of C:\OpenServer\domains\localhost\site\templates\head.inc)
This error message was shown because you are logged in as a Superuser. Error has been logged.

error here

$summary = substr($child->text, 0, 100);

if(($pos = strrpos($summary, ".")) !== false) {
$summary = substr($summary, 0, $pos);
}

[adrian]

Well chances are that you don't have an images field in that template - that is why it can't find the first() image from it.

That code won't be a complete drop-in example for you. I don't imagine you need the entire  <div class="portfolio-image-holder"> xxxx </div>  section.

Start by removing that and see what you get.

happened now displayed

displays the full article

does not reduce the number of characters

What are the options?

[ryan]

The above code should work. Just make sure you are outputting the truncated version ($summary) and not $child->text. 

echo $summary; // do this
echo $child->text; // do not do this
