在PHP中使用echo后未显示HTML元素

Question

I am creating a form to update a database and used PHP to query the database and get current values before filling them in as the values already in the input boxes. I used echo to create the HTML elements while inserting the PHP variables however, the elements created aren't being displayed. Here are a couple of the inputs that I tried to make:

// Album Price
echo "<div class=\"row horizontal-center\">" .
"<input type=\"number\" step=\"0.01\" value=\"" . htmlspecialchars($albumPrice) . "\" name=\"albumPrice\"
" .
"</div>";

// Album Genre
echo "<div class=\"row horizontal-center\">" . 
"<input type=\"text\" value=\"" . htmlspecialchars($albumGenre) . "\" name=\"albumGenre\"
" .
"</div>";

Thanks in advance :)

Answer 1

Your input elements are not properly closed with a > character. This code should work:

"<input type=\"number\" step=\"0.01\" value=\"" . htmlspecialchars($albumPrice) . "\" name=\"albumPrice\" />
" 

Note the /> added in the end of the line. (the / due to <input> not having a closing tag)
