Truncating Text

[LewisP]

So I'm trying to truncate text for a datatable connected to a database so that entries that are long don't ruin the styling of the table

Example of untruncated text:

 

I found this documentation on a div class inside IPS suite for truncating, so I went ahead and edited my pages template to the following:

  	<div class='ipsDataItem_generic ipsDataItem_custom data-ipsTruncate'>
    	{$row['whatever']}
	</div>

And it had no effect (original 160 chars, new div style still 160)

 

Any help would be appreciated, I'm looking to truncate to 20 characters max

size
(Mixed; optional; default 100)

Specifies the height the element should be; the excess text is truncated. Three types of value are accepted:

• Selector, e.g. #someElementID
  When a selector is provided, the height of the widget element will be set to the outerHeight of the first element that matches the selector.
• Lines value, e.g. 3 lines
  Text can be truncated to a certain number of lines of text, taking into account current formatting applied to the text (Note: lines is always plural).
• Number e.g. 100
  A simple number value can be provided, which will truncate the text to that number of pixels.

 

So you can't use it to truncate by number of characters. You need to use php code instead if you want to do that.

@DawPi Actually that was what I tried originally

	protected function manage()
	{
		// This is the default method if no 'do' parameter is specified
		$table = new \IPS\Helpers\Table\Db( 'cms_pages', \IPS\Http\Url::internal( 'app=appnamehere&module=modulenamehere&controller=testdev' ) );
		$table->rowsTemplate = array( \IPS\Theme::i()->getTemplate('whatev', 'whateverrr', 'front'), 'rowssss' );
		$table->classes = array('ipsDataList_zebra');
		
		$table->include = array( 'page_id', 'page_seo_name', 'page_type', 'page_theme', 'page_default');
		
		$table->sortBy      = $table->sortBy ?: 'page_id';
		$table->sortDirection = $table->sortDirection ?: 'desc';
		
		$table->parsers = array(


			'page_seo_name'	=> function($val, $chars = 20)
			{
				    if(strlen($val) > $chars) {
        			$val = $val.' ';
        			$val = substr($val, 0, $chars);
        			$val = substr($val, 0, strrpos($val ,' '));
        			$val = $val .'...';
				}
				return $text;
			},
		);
		
		/* Display */
		\IPS\Output::i()->title		= \IPS\Member::loggedIn()->language()->addToStack('aaaa');
		\IPS\Output::i()->output	= \IPS\Theme::i()->getTemplate('donate')->outgoings((string) $table);

	}

 

The result was that it just hid the text entirely. I feel like I'm making a simple mistake here

			'page_seo_name'	=> function($val, $chars = 20)
			{
				    if(strlen($val) > $chars) {
        			$val = $val.' ';
        			$val = substr($val, 0, $chars);
        			$val = substr($val, 0, strrpos($val ,' '));
        			$val = $val .'...';
				}
				return $text;
			},

You're returning $text. Use $val instead. $text variable isn't specified.

return $val;

Oops 

 

returning $val puts us back to square 1 though

		$table->parsers = array(


			'page_seo_name'	=> function($val, $chars = 20)
			{
				    if(strlen($val) > $chars) {
        			$val = $val.' ';
        			$val = substr($val, 0, $chars);
        			$val = substr($val, 0, strrpos($val ,' '));
        			$val = $val .'...';
				}
				return $val;
			},

You are passing $chars=10 as the second parameter, however what is actually passed to the callback function as the second parameter is an array containing the entire row. Instead of trying to define this as a function parameter, you could do something like this instead

$chars = 20;

	$table->parsers = array(
			'page_seo_name'	=> function( $val ) use( $chars )
			{
				    if(strlen($val) > $chars) {
        			$val = $val.' ';
        			$val = substr($val, 0, $chars);
        			$val = substr($val, 0, strrpos($val ,' '));
        			$val = $val .'...';
				}
				return $val;
			},

Since 4.2 you can add classes to rows

Add 

$table->rowClasses = array('page_seo_name' => array('ipsTable_wrap'));
