Child theme functions bug

Not sure what you mean by “anything”, what exactly are you trying?

Any random code that I want to change and put in functions.php in child theme.

You can’t put random code into functions.php, it’s PHP and you have to use PHP syntax. There are other reasons why it could break, but we’d need to see the code you’re using.

I have putted this:

`<script type=”text/javascript”>
// Check if first slider image is loaded, and load flexslider on document ready
jQuery(document).ready(function(){
var firstImage = jQuery(‘#flexslider-featured’).find(‘img’).filter(‘:first’),
checkforloaded = setInterval(function() {
var image = firstImage.get(0);
if (image.complete || image.readyState == ‘complete’ || image.readyState == 4) {
clearInterval(checkforloaded);

jQuery(‘#flexslider-featured’).flexslider({
animation: “slide”,
useCSS: false, // Fix iPad flickering issue
slideshow: true,
directionNav: true,
controlNav: true,
pauseOnHover: true,
slideshowSpeed: 4000,
animationSpeed: 400,
smoothHeight: true,
touch: false
});

}
}, 20);
});
</script>`

Yeah that’s JavaScript and not PHP, so that will break your site.

So this can′t go in functions.php in child theme? How can I edit this in child theme? I must create another stylesheet and put it in child theme folder oor?

Try putting your JavaScript into a ‘.js’ file, just this bit:

// Check if first slider image is loaded, and load flexslider on document ready
jQuery(document).ready(function(){
var firstImage = jQuery('#flexslider-featured').find('img').filter(':first'),
checkforloaded = setInterval(function() {
var image = firstImage.get(0);
if (image.complete || image.readyState == 'complete' || image.readyState == 4) {
clearInterval(checkforloaded);

jQuery('#flexslider-featured').flexslider({
animation: "slide",
useCSS: false, // Fix iPad flickering issue
slideshow: true,
directionNav: true,
controlNav: true,
pauseOnHover: true,
slideshowSpeed: 4000,
animationSpeed: 400,
smoothHeight: true,
touch: false
});

}
}, 20);
});

And then enqueue that ‘.js’ file through your Child Theme functions.php file: https://codex.www.ads-software.com/Function_Reference/wp_enqueue_script
