📝 How to Remove Carriage Returns from Output of a String 📝

Are you struggling with removing carriage returns from the output of a string? Don't worry, you're not alone! This can be a common issue, especially when working with CMS platforms like WordPress. But fear not! In this guide, we'll explore some easy solutions to help you tackle this problem and get your output back on track. Let's dive in! 💪

The Problem in Context:

So, you're using WordPress as a CMS and want to allow user inputs to populate info windows in a Google Map script. Everything seems to be working fine until there's HTML in the custom field - it breaks the script 😞. You've looked into htmlspecialchar and htmlentities, but stripping everything out is not the solution you're looking for. You would rather escape the HTML and keep it intact. Any suggestions? You're new to PHP and could really use some pointers.

Easy Solutions:

After some investigation and suggestions from helpful individuals, you've come across a few approaches that are worth trying. Let's take a look at them:

1. Escaping HTML with esc_js:

TheDeadMedic suggested using esc_js, which seemed promising. However, it printed all of the actual HTML code instead of rendering it. While this solution didn't work for your specific case, it might be useful in other scenarios.

2. A Better Alternative: strip_tags:

Thank you to nickfs for providing a slightly better solution! However, there's still an issue with carriage returns in the output, making it not so great for a CMS. But don't worry, we've got another trick up our sleeves.

3. Utilizing str_replace:

Let's try using the str_replace function to get rid of those pesky carriage returns. Here's an example snippet that demonstrates how you can remove carriage returns from the output string in your specific scenario:

<?php
$post_id = 207; // Wordpress Post ID
$my_post = get_post($post_id);
$mapTitle  = $my_post->post_title;
$mapIMG = get_post_meta($post_id, 'mapImage', true);
$snip = get_post_meta($post_id, 'mapExcerpt', true);
$lat = get_post_meta($post_id, 'lat', true);
$long = get_post_meta($post_id, 'long', true);
$pass_to = '<div class="span-8"><div class="mapTitle">'.$mapTitle.'</div><div class="mapContent">'.$snip.'</div></div>';
$trimmed = str_replace(["\r", "\n"], "", $pass_to);
?>
var point = new GLatLng('<?php echo $lat; ?>','<?php echo $long; ?>');
var marker = createMarker(point,"<?php echo $mapTitle; ?>", '<?php echo addslashes($trimmed); ?>');
map.addOverlay(marker);

In this example, we use the str_replace function to replace the carriage returns (\r) with an empty string. This effectively removes them from the output string, allowing the script to work seamlessly without any unwanted line breaks.
