    Hi there! I am using wordpress, and I am unable to use php codes in my pages.
    Somewhere I found that using shortcodes, one can use php code anywhere.
    Please let me know how can I do it.
    I followed many guides, did some work in functions.php too, but still it shows Error 500.

    Please let me know, my php code – 

    
// Add Shortcode
function custom_shortcode_logincall() {

	<?php   global $current_user;
	                                $second_website_url = 'http://secondwebsite.com'; // put your second website url
	                                $user_email = $current_user->user_email;
	                                $user_login = $current_user->user_login;
	                                if($user_email != ''){
	 
	                                    $email_encoded = rtrim(strtr(base64_encode($user_email), '+/', '-_'), '='); //email encryption
	                                    $user_login_encoded = rtrim(strtr(base64_encode($user_login), '+/', '-_'), '='); //username encryption
	                                    echo '<a href="'.$second_website_url.'/sso.php?key='.$email_encoded.'&detail='.$user_login_encoded.'" target="_blank" rel="noopener noreferrer">Link to second website</a>';
	 
	                        }?> 

}
add_shortcode( 'logincall', 'custom_shortcode_logincall' );

    Any shortcode name will be appriciated!

    Shortcodes should not echo content — they return a string that’s printed as part of displaying a post’s content. So, change your echo lines to append content to a string and return that string at the end of the function. Also, you have a <?php there that’s unnecessary. That’s probably what’s causing the 500 error.

    Many thanks for the advice. Just please correct my syntax, your pleasure!
    Please post the syntax that should be pasted on functions.php

    What you’re asking me to do is rewrite your bad code for you. I already told you about the two problems with your shortcode’s code. Please give that a try and let me know if it works.

    In addition, you don’t need the ?> after the closing brace.

    Hey is that bad coded? I am totally a newbie of 14 years old and I have only 1 year of web development experience. Still I understood the error, soon I will tell you whether it worked or not?

    Yes, I tried.
    1. I removed ?> and <?php from the code.
    2. I replaced echo –> return “CODE HERE”;

    Now when I saved, it returned to Server Error 500. Whole website is not running. Kindly help.

    Hello @allroundernaman ,

    Please use this code:

    function custom_shortcode_logincall() {

	ob_start();

	global $current_user;
	$second_website_url = 'http://secondwebsite.com'; // put your second website url
	$user_email = $current_user->user_email;
	$user_login = $current_user->user_login;
	if($user_email != ''){
		$email_encoded = rtrim(strtr(base64_encode($user_email), '+/', '-_'), '='); //email encryption
		$user_login_encoded = rtrim(strtr(base64_encode($user_login), '+/', '-_'), '='); //username encryption
		?>
		<a href="<?php echo $second_website_url.'/sso.php?key='.$email_encoded.'&detail='.$user_login_encoded; ?>" target="_blank" rel="noopener noreferrer">Link to second website</a>
		<?php

	}

	$output_string = ob_get_contents();
	ob_end_clean();
	return $output_string;

}
add_shortcode( 'logincall', 'custom_shortcode_logincall' );

    This is working for me.

    Thanks,

    Ok very much thanks! Just I want to ask that seek in 14th line, you have written *<?php* so is that correct?
    I have not tested yet. Still asking!

    Yes that is correct because on line 12 we close the PHP tag( ?> ) and line 14 we start PHP tag again( <?php ). Line no 13 have HTML tag.
