How to echo script in php

Question

I am using the shortcode execute plugin in wordpress.

This simply allows me to write shortcode like this [email_spamproof]

But I am trying to echo a script.

Answer 1

It is easy. Save your javascript code in a new one file and then use this to load it:

include('myjavascript.php');

Then you will use the include option as a echo because the web will understand your code as HTML and you execute it when you want with php (like echo).

Answer 2

You could write " in your javasript code, and then only use single quotes(') in your php echo.

A more suitable method is to use escape characters in your javascript code "\'" (without the double quotes)

Answer 3

The \ character is the escape character. Prepend one to each internal use of the character used to delimit the string.

Alternatively, use a HEREDOC.

Answer 4

You can either escape them with a back slash: echo 'It\'s cold'; or use heredoc:

echo <<<END
lots of text here
END;

Answer 5

The right code:

<?php

echo "<script type='text/javascript'>
    <!-- 
    // spam protected email
    emailE=('enquiries@' + 'example.co.uk')
    document.write('<a title='E-mail Example' href='mailto:' + emailE + ''>' + emailE + '</a>')
     //-->
    </script>
    <noscript>
        <span class='spam-protected'>Email address protected by JavaScript. Please enable JavaScript.</span>
    </noscript>";

?>

Answer 6

You need to escape them and then concatenate the variables :

(Also I dont know if you realize, but you are echoing a commented out section of javascript)

echo '<script type="text/javascript">    
  <!--      // spam protected email     
  emailE=("enquiries@" + "example.co.uk")     
  document.write(\'<a title="E-mail Example" href="mailto:'.emailE.'">'.emailE.'</a>\')      
  //-->     
  </script>     
  <noscript>         
  <span class="spam-protected">Email address protected by JavaScript. Please enable JavaScript.</span>     
  </noscript>';
