Snippets and blank lines in the html

Hi everyone,

I am using MODx version 0.6.9.1, I am calling a snippet before the doctype tag of my template.

[[snippet1]]
<!DOCTYPE ...

The content of the snippet is:
<?php
$modx->setPlaceholder(’templatePath’, ’assets/templates/site_template/’);
?>

The snippet is not outputting any html, it is just setting a placeholder, but there is a blank line in the rendered html where the snippet was placed.
Does anyone know of any way to get rid of the blank line?

Thanks

Hi,

you could use a plugin for this with some php to remove blank lines

Here is a sample

$e = &$modx->Event;

switch($e->name) {
case ’Choose the best event’:
$output = preg_replace("/(^[\r\n]*|[\r\n]+)[\s\t]*[\r\n]+/", "\n", $modx->documentOutput);
$modx->documentOutput = $output;
break;
}

I’m not sure about the modx event to choose, perhaps OnWebPageComplete

:-)

P.S: all blank lines in your html will be removed

Try putting the snippet on the same line as the DOCTYPE, it it does not return anything then it should not be a problem.

Thanks for the replies guys.

I prefer to keep [[snippets]] or {{chunks}} on their own line to make it easier to read the code, but your suggestion worked like a charm dev_cw.

Calling the snippet at the start of the chunk still produced the blank line.

Heliotrope, your suggestion got me think about setting the placeholder with a plugin, so I came up with:

//with checkbox for 'OnWebPageInit' ticked. 'OnWebPagePrerender' didn't seem to work.
$e = &$modx->Event;
switch($e->name) 
{
    case 'OnWebPageInit':
        $modx->setPlaceholder('templatePath', 'assets/templates/template_name/');
    break;
}

If you’re not into switches

if ($e->name == 'OnWebPageInit')
{
    $modx->setPlaceholder('templatePath', 'assets/templates/template_name/');
}

-------- or

$modx->setPlaceholder('templatePath', 'assets/templates/template_name/');
$mySampleChunk = $modx->getChunk('mySampleChunk');
echo $mySampleChunk;

Thanks for the feedback guys. So many ways to do something in MODx

, really shows what a powerful and flexible framework it is!
