If statment to echo an image if var=EUR doesnt work - php

Question

This code added currency switcher to a menu,
But unfortunately I don't have access to MySQL database so I can't add image "flag" to each currency, then execute them
So I tried to use if statement.
This is my code:
$currency_switcher_enable = houzez_option('currency_switcher_enable');
$is_multi_currency = houzez_option('multi_currency');
if( $currency_switcher_enable != 0 && $is_multi_currency != 1 ) {
if (class_exists('FCC_Rates')) {
$supported_currencies = houzez_get_list_of_supported_currencies();
if (0 < count($supported_currencies)) {
$current_currency = houzez_get_wpc_current_currency();
echo '<li class="btn-price-lang btn-price">';
echo '<form id="houzez-currency-switcher-form" method="post" action="#" class="open">';
echo '<button id="houzez-selected-currency" class="btn dropdown-toggle" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true"><span>' . $current_currency . '</span> <i class="fa fa-sort"></i></button>';
echo '<ul id="houzez-currency-switcher-list" class="dropdown-menu" aria-labelledby="dropdown" style="display:none;">';
foreach ($supported_currencies as $currency_code) {
echo '<li data-currency-code="' . $currency_code . '">' . $currency_code . '</li>';
if (data-currency-code='EUR') {
echo '<img src="images/euro-flag.png"';
if (data-currency-code='TR') {
echo '<img src="images/turkish-flag.png"';
}
}
echo '</ul>';
echo '<input type="hidden" id="houzez-switch-to-currency" name="houzez_switch_to_currency" value="' . $current_currency . '" />';
echo '<input type="hidden" id="currency_switch_security" name="nonce" value="' . wp_create_nonce('houzez_currency_converter_nonce') . '"/>';
echo '</form>';
echo '</li>';
}
}
}
?>
But it doesn't work? What I'm doing wrong?
This is the original code:
$currency_switcher_enable = houzez_option('currency_switcher_enable');
$is_multi_currency = houzez_option('multi_currency');
if( $currency_switcher_enable != 0 && $is_multi_currency != 1 ) {
if (class_exists('FCC_Rates')) {
$supported_currencies = houzez_get_list_of_supported_currencies();
if (0 < count($supported_currencies)) {
$current_currency = houzez_get_wpc_current_currency();
echo '<li class="btn-price-lang btn-price">';
echo '<form id="houzez-currency-switcher-form" method="post" action="#" class="open">';
echo '<button id="houzez-selected-currency" class="btn dropdown-toggle" type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true"><span>' . $current_currency . '</span> <i class="fa fa-sort"></i></button>';
echo '<ul id="houzez-currency-switcher-list" class="dropdown-menu" aria-labelledby="dropdown" style="display:none;">';
foreach ($supported_currencies as $currency_code) {
echo '<li data-currency-code="' . $currency_code . '">' . $currency_code . '</li>';
}
echo '</ul>';
echo '<input type="hidden" id="houzez-switch-to-currency" name="houzez_switch_to_currency" value="' . $current_currency . '" />';
echo '<input type="hidden" id="currency_switch_security" name="nonce" value="' . wp_create_nonce('houzez_currency_converter_nonce') . '"/>';
echo '</form>';
echo '</li>';
}
}
}
?>

Answer 1

You have many fails here:
The first is as #kerbh0lz mentioned, the "=" and "==" is not the same purpose. here yours is wrong.
Second your second currency If is in the 1st Currency If so it wont ever pass by.
Third you are comparing a string without quote or a var without $ before data-currency-code so instead you should use $currency_code
Try this:
foreach ($supported_currencies as $currency_code) {
echo '<li data-currency-code="' . $currency_code . '">' . $currency_code . '</li>';
if ($currency_code =='EUR')
echo '<img src="images/euro-flag.png"';
elseif ($currency_code == 'TR')
echo '<img src="images/turkish-flag.png"';
}
