If File Exists Post Image, if Not, post title.

It’s not a good idea to use the post title as it can contain characters that are not allowed in filenames and can change at any time.

Why not use custom fields to store the url or the filename of the image for the post?

Or a featured image?

If you still want to use the title and file_exists():
Use get_the_title() if you want to store the title in a variable.
I think file_exists() needs the path (not the url) to the image.
To get the path to your template directory use get_template_directory and if you are using a child theme use get_stylesheet_directory
And ask in a php forum how you can get it working with file_exists().

Genius, thanks man, with your direction I came up with this:

<?php
$image = get_template_directory() . "/images/" . get_the_title() . ".png";
$image2 = get_template_directory_uri() . "/images/" . get_the_title() . ".png";

if (file_exists($image)) {
		echo "<img src=" . $image2 . ">";
} else {
		echo the_title("<h1 class='title'>","</h1>");
}
?>

Works just fine, is there anything you see that can be condensed?

better yet, like you stated, on pages, is there a if(featured_image!=null) { echo “<img>”;
} else {
echo the_title();?
}

You can check for a featured image with:

Not sure if that’s what you mean though.

Thanks for the help, I’ve sorted all out with your direction, the perfect set up for me was

<?php
if (has_post_thumbnail()) {
	the_post_thumbnail('full');
} else {
		echo the_title("<h1 class='title'>","</h1>");
}
?>

Thanks!

You’re welcome. I’m glad you’ve got it resolved ??
