• PHP parse/syntax errors; and how to solve them? 17 answers

I know this is a dumb question but I don't know anything about php and I want to insert a list in php to use it late as a shortcode. Here is the code that I have problem with in functions.php

function optionalone_function() {
echo " <ul>
<li>5 pages Web</li>
<li><i class="icon-circle-check"></i> one</li>
<li><i class="icon-circle-check"></i> two</li>
<li><i class="icon-circle-check"></i> three</li>
<li><i class="icon-circle-check"></i> four</li>
<li><i class="icon-circle-check"></i> five</li>
<li><i class="icon-circle-Check"></i>six</li>
<li><i class="icon-circle-check"></i> seven</li>
</ul>
";
}
add_shortcode( 'optionalone', 'optionalone_function' );

</div>

Change the double quotes in the class part to the single quotes. PHP is getting confused. Do like this:

function optionalone_function() {
echo " <ul>
<li>5 pages Web</li>
<li><i class='icon-circle-check'></i> one</li>
<li><i class='icon-circle-check'></i> two</li>
<li><i class='icon-circle-check'></i> three</li>
<li><i class='icon-circle-check'></i> four</li>
<li><i class='icon-circle-check'></i> five</li>
<li><i class='icon-circle-Check'></i>six</li>
<li><i class='icon-circle-check'></i> seven</li>
</ul>
";
}
add_shortcode( 'optionalone', 'optionalone_function' );

Inside the double quotes (example: "this is inside"), you need to put the single quotes. If you put the double quotes inside, that means you have finished entering the string, double quotes have ended, and you are confusing the PHP. Do like I wrote to you, instead. If everything else you wrote is correct, you should be good.
