PHP into html <option...> code

Question

I'm trying to put this string that work fine as php:

if ($sortvalue == $sort[3]) { echo 'selected=' ;}

into this code:

echo '<select onchange="this.form.submit();" name="sort">
<option value="'.$sort[3].'" HERE_THE_PHP_CODE>Price</option>
[..]
</select>';

I tried a lot of syntax but I got always a blank page.

check your error log or add in the top error_reporting(E_ALL); ini_set('display_errors', 1); — Leandro Papasidero

$selected = '';

if ($sortvalue == $sort[3]) { $selected = 'selected'; }

echo '<select onchange="this.form.submit();" name="sort">
<option value="'.$sort[3].'" $selected>Price</option>
</select>';

This should do what you want. (the reply by Osama has an error in the if statement)

To keep the code clean you should use the ternary operator. It will allow you to do an if statement inside your echo.

echo '<select onchange="this.form.submit();" name="sort">
<option value="'.$sort[3].'" ' . ($sort[3] == $sortvalue ? 'selected' : '') . '>Price</option>
[..]
</select>';

Thanks! That worked! How is it possible just not to insert the "if" condition and make it works anyway??? I would never find this solution by myself..

@Rain_xx you are using the if condition by using the ternary operator, for more information, please check the link provided by Marwelln
