return html button with onclick cookie value

Question

For a number of wordpress websites i am creating a cookiewall. So in the plugin file i created a shortcode like this:

function agreebutton($atts, $content = null) {
extract(shortcode_atts(array($atts),$content));
return '<button type="submit" onClick="SetCookie('clickagree','yes')">';
do_shortcode($content) . '</button>'; 
add_shortcode('button', 'agreebutton');

And in a custom template i set a SetCookie function, so if clicked on the button, the cookie would be placed:

<script>
function SetCookie(cookieName,cookieValue) {
var today = new Date();
var expire = new Date();
var nDays=365
expire.setTime(today.getTime() + 3600000*24*nDays);
document.cookie = cookieName+"="+escape(cookieValue)+";expires="+expire.toGMTString(); }</script>

Now the problem is that when i try to return the onClick="SetCookie ('clickagree', 'yes') i get a syntax error unexpected 'clickagree' (T_STRING). Escaping doesnt solve it, and for a shortcode to work you need to return instead of echoing.

Any ideas?

The sample PHP code you posted is not complete, I guess you made your example too short... But look how your code is rendered here, there's clearly an error with the quotes you're using.

You were right, after changing the quotations it did work. Thank you! — Webdever, May 18 '18 at 08:51

Ok so after changing the quotations this worked:

return '<button onClick="SetCookie( \'clickagree\',\'yes\')">' . do_shortcode($content) . '</button>';
